Events

January

January 6 – Ken Griffey Jr. and Mike Piazza are elected to the Hall of Fame by the Baseball Writers' Association of America. In his first year on the ballot, Griffey receives a record 99.3 percent of the vote, being named on all but three of the 440 ballots, to surpass the 98.84 percent Tom Seaver received in 1992. Piazza, in his fourth year on the ballot, receives 83.0 percent of the votes, up from the 69.9 percent he received in 2015. Griffey becomes the first player drafted #1 overall (1987) to be inducted into the Hall of Fame, while Piazza becomes the lowest draftee to be inducted, having been selected in the 62nd round, 1390th overall (1988).^[67] A player needs 75 percent to gain election. This time, the vote total dropped by 109 from last year, due to the new rules writers who have not been active for 10 years lost their votes. Falling shy of enshrinement was Jeff Bagwell (71.6%). The other players to be named on more than half the 440 ballots were Tim Raines (69.8%), Trevor Hoffman (67.3%) and Curt Schilling (52.3%).^[68]

February

February 12 – Relief pitcher Jenrry Mejía of the New York Mets is permanently banned from Major League Baseball for a third failed drug test. Mejía had received an 80-game suspension in April, after testing positive for use of stanozolol. On July 28, three weeks after serving the suspension, he failed a test for stanozolol again as well as boldenone, and was suspended for 162 games. Mejía is allowed to apply for reinstatement after one year of the ban, but must be out of Major League Baseball for a minimum of two years if he is to be reinstated.^[69]

March

March 15 – The United States Department of the Treasury announced that American employers would be allowed to hire Cuban citizens to work in the United States. This announcement theoretically means that Major League Baseball teams would be able to sign Cuban baseball players directly instead of requiring them to defect from Cuba and establish residence in another country before signing.^[70]

April

April 5 – At Petco Park, the Los Angeles Dodgers defeat the San Diego Padres 15–0 in the most lopsided shutout on Opening Day. According to STATS, the previous record was the Pittsburgh Pirates' 14–0 victory over the Cincinnati Reds in . The game also marks the managerial debut of the Dodgers' Dave Roberts, a former Dodger and Padre player and San Diego coach for the previous five seasons, as well as Andy Green guiding the Padres, resulting in the first Opening Day meeting of two rookie managers since Florida's Fredi González and Washington's Manny Acta in .^[71]
April 8 :
- At Coors Field, rookie Trevor Story of the Colorado Rockies becomes the fifth player in Major League history to hit home runs in each of his team's first four games of a season. He hits two home runs, his fifth and sixth of the season, in the Rockies' 13–6 loss to the San Diego Padres, off starter Colin Rea in the fourth inning and reliever Ryan Buchter in the ninth. Story, who had already made history by becoming the first player to hit two home runs in his Major League debut in an Opening Day game, and hit three in each of his first three Major League games, joins Willie Mays, Mark McGwire, Nelson Cruz and Chris Davis as players who have homered in each of their team's first four games of a season. He also breaks the record of five home runs in his team's first four games, held jointly by Lou Brock in and Barry Bonds in .^[72]
- The St. Louis Cardinals became the first team in Major League Baseball history to have three players come off the bench to go deep in the same game. Jeremy Hazelbaker, Aledmys Díaz and Greg Garcia pinch-hit solo home runs in the final three innings, as the Cardinals prevailed with a 7–4 win over the Atlanta Braves at Turner Field.^[73]
April 21 – At Great American Ball Park, Jake Arrieta of the Chicago Cubs no-hits the Cincinnati Reds 16–0. He walks four and strikes out six and is backed by five home runs: two by Kris Bryant, including a grand slam, and one each by Ben Zobrist, Anthony Rizzo and Arrieta's catcher, David Ross. Arrieta, who no-hit the Los Angeles Dodgers on August 30,, joins Ken Holtzman as the only Cubs pitchers to throw multiple no-hitters in modern history. The Arrieta no-hitter is also the first against the Reds in regular season play since the Philadelphia Phillies' Rick Wise on June 23,, though Roy Halladay had no-hit them during the 2010 National League Division Series. It also sets a modern-day record for most lopsided score in a no-hitter, topping the 15–0 score in Frank Smith's no-hitter on September 6, . Previously, Pud Galvin had pitched an 18–0 no-hitter on August 4, .^[74]
August 26 – Andrew McCutchen hit three home runs for the second time of his career to lead the Pittsburgh Pirates to a 9–4 victory over the Colorado Rockies at Petco Park. As a result, McCutchen is only the fourth player in Pirates history with a pair of three-homer games, being the others Hall of Famers Ralph Kiner, Roberto Clemente and Willie Stargell.^[75]
April 29 – At Chase Field, Colorado Rockies shortstop Trevor Story hit his 10th home run of the season, tying the Major League Baseball rookie record for most home runs in the month of April, set by Chicago White Sox slugger José Abreu in 2014. Story belted a two-run shot off pitcher Robbie Ray in the fifth inning, helping the Rockies cruise to a 9–0 victory over the Arizona Diamondbacks. In hitting his 10th home run in 21 games, Story tied Boston Red Sox first baseman George Scott in 1966 as the fastest player in major league history to reach that home run total.^[76]

May

May 6 – David Ortiz hit a two-run home run off Michael Pineda in the first inning for a 2–0 Boston Red Sox lead over the New York Yankees that was a milestone blast. It was home run No. 510 in Ortiz's career, moving him past Gary Sheffield and into 25th place on the all-time list. It was also the No. 452 home run for Ortiz in a Red Sox uniform, tying him with Hall of Famer Carl Yastrzemski for second in team history. Only the legendary Ted Williams has hit more homers (521) in a Boston uniform. Besides, the long ball was Ortiz's 50th all-time against the Yankees, placing him sixth all-time in that category, behind Jimmie Foxx (70), Williams (62), Manny Ramírez (55), Hank Greenberg (53) and Yastrzemski (52). But it was not enough to propel Boston to a victory, as Rick Porcello gave up a home run to Yankees outfielder Aaron Hicks in the bottom of the seventh that snapped a 2–2 tie and sent the Sox to a 3–2 defeat at Yankee Stadium. Next up on the career home run list for Ortiz is former New York Giants great Mel Ott, who ranks 24th with 511 homers.^[77] ^[78]
May 7 – Bartolo Colón hit his first Major League career home run at Petco Park, a two-run shot off the San Diego Padres' James Shields.^[79] It took Colón until the age of 42 to achieve the long-ball feat, which traveled 365 feet, making him the oldest player in major league history to finally break through with a home run, according to the Elias Sports Bureau.^[80] Previously, 40-year-old Randy Johnson belted his first homer in Milwaukee on September 19, 2003. At 42 years, 349 days, Colón also became the second-oldest New York Mets player to hit a homer. Julio Franco homered for the Mets on May 4, 2007, when he was 48 years, 254 days old. Furthermore, Colón pitched solid innings of three-run, six hits ball and struck out six in the 6–3 victory against San Diego.^[79]
May 11 – At Nationals Park, Max Scherzer of the Washington Nationals ties a nine-inning Major League record by striking out 20 Detroit Tigers in the Nationals' 3–2 victory. After striking out Justin Upton for the second out of the ninth inning, Scherzer, who had pitched for the Tigers from 2010 to 2014, comes within one strikeout of tying the all-time record set by Tom Cheney in 1962 (Cheney, while with the Washington Senators, struck out 21 Baltimore Orioles in 16 innings). However, James McCann, who had already struck out three times, grounds out for the final out. Scherzer ties the nine inning record shared by Roger Clemens (twice, in 1986 and 1996), Kerry Wood (1998) and Randy Johnson (2001, in a game that lasted 11 innings).^[81]
May 17 – Off to one of the worst starts in their history, the Atlanta Braves dismissed manager Fredi González. The Braves dropped to an MLB-worst 9–28 record after an 8–5 loss to the Pittsburgh Pirates. Brian Snitker, manager of Atlanta's Triple-A Gwinnett Braves, replaced González as the team interim manager through the end of the season. González was at the helm from 2011 and compiled an overall record of 434–413 during his tenure as Atlanta's skipper. He remained a loyal contributor as his rosters were weakened by the massive rebuild the Braves began last year, as they fell shy of expectations in 2014 and have not posted an average of .500 since. The Braves also dismissed bench coach Carlos Tosca, who had served in that capacity for González dating back to their time together with the Florida Marlins from 2007 to 2010. Terry Pendleton became the bench coach, while his previous duties as first-base coach were filled by Eddie Pérez.^[82]
May 20- It is announced that the 2019 season will be the Texas Rangers last season at Globe Life Park with Globe Life Field scheduled to open in time for the 2020 season. The Rangers have cited heat as the reason for low attendance at Globe Life Park.
May 31 – Boston Red Sox right fielder Mookie Betts belted three home runs, one to each field, and drove in five runs in a 6–2 victory over the Baltimore Orioles at Camden Yards. Betts opened the game with a home run to center field, added a three-run shot in the second inning over the fence down the left-field line, and a solo homer to right field in the seventh for his first three-homer career game. Betts also impressed in the field with a dazzling diving catch in right-center field, robbing Paul Janish of an extra-base hit in the seventh. In addition, Betts became the first Red Sox leadoff hitter to go deep three times in one game, according to research by Elias Sports Bureau.^[83]

June

June 2 – At Petco Park, the Seattle Mariners set a franchise record by erasing a 10-run deficit to defeat the San Diego Padres, 16–13. Trailing 12–2 after five innings, the Mariners score five runs in the sixth, then nine in the seventh, recording seven straight singles with two out in the latter inning. Their previous comeback record was an eight-run deficit, which they overcame to defeat the Anaheim Angels 11–10 on April 15, .^[84]
June 15 – At Petco Park, Ichiro Suzuki of the Miami Marlins collects two hits to give him 4,257 in his career combined in the Nippon Professional Baseball and Major League Baseball, surpassing Pete Rose who is the all-time MLB leader with 4,256 hits. After beating out an infield single in the first inning of the Marlins' 6–3 loss to the San Diego Padres, Suzuki doubles in the ninth inning for the record-breaking hit. The two hits give Suzuki 2,979 in his Major League career; he had collected 1,278 while in Japan's Pacific League.^[85]
June 17 – David Ortiz hit his 521st career home run in an 8–4 loss to the Seattle Mariners at Fenway Park. With his fourth-inning solo home run against pitcher Hisashi Iwakuma, Ortiz tied Hall of Famers Willie McCovey, Frank Thomas and Ted Williams for 19th place on the all-time list. At his present pace, Ortiz also could catch Jimmie Foxx (534) and even Mickey Mantle (536) on the MLB's most home runs list.^[86]
June 27 – Kris Bryant hit three home runs with two doubles and drove in six runs, leading the Chicago Cubs to an 11–8 victory over the Cincinnati Reds at Great American Ball Park. Bryant became the first player in MLB history to hit three homers and two doubles in a single game, as his 16 total bases also were a Chicago Cubs record, breaking the previous team's mark of 14 shared by Ernie Banks (1962), George Mitterwald (1974) and Aramis Ramírez (2004). Cubs starter Jake Arrieta gave up five runs and five walks in five innings but still was credited with the win.^[87]
June 29 – The Sonoma Stompers signed female pitchers Stacy Piagno and Kelsie Whitmore, making the Stompers the first professional baseball club since the 1950s to have women take the field, when Mamie Johnson, Constance Morgan and Toni Stone became the first women to play along men in the Negro leagues. Sonoma, a member of the independent Pacific Association of Professional Baseball Clubs, previously made international news when they signed pitcher Sean Conroy, who became the first openly gay player to ever play baseball at the professional level.^[88]
June 30 :
- The Coastal Carolina Chanticleers won the College World Series (CWS) at TD Ameritrade Park in Omaha, Nebraska, defeating the Arizona Wildcats, 4–3, in the deciding game of the best-of-three championship series. Chanticleers pitcher Andrew Beckwith was named the Most Outstanding Player of the CWS, while Coastal became the first team since the Minnesota Golden Gophers in 1956 to win the CWS in its first appearance in the event. The championship, the first national title for Coastal Carolina and also the first for the Big South Conference in any team sport, took place the day before Coastal joined the Sun Belt Conference.^[89]
- Carlos Carrasco struck out a season-high 14, while Jason Kipnis and Rajai Davis hit solo home runs, and the Cleveland Indians matched a franchise record by winning their 13th consecutive game of the season, beating the Toronto Blue Jays, 4–1, at Rogers Centre.^[90] The 13-win streak is the longest by any MLB team in the season, as well as the longest for the Indians since they won 13 straight in August 1951.^[91] Cleveland had also won 13 in a row between April and May 1942.^[92]

July

July 1 – Major League Baseball imposed unprecedented penalties on the Boston Red Sox organization for rules violations relating to their acquisition of several international amateur free agents for the 2016–17 period. Boston was limited last year to spending a maximum of $300,000 on international amateur talent after exceeding its spending limit near the end of the 2014–15 signing period by spending $62 million on Cuban prospect Yoan Moncada. Furthermore, Boston circumvented that limitation by packaging more premium prospects with lesser prospects, paying $300K for multiple prospects that employed the same trainers/agents and then allowing the players' representatives to divide the share of the collective sums to the top five prospect of the package, with the lesser prospects receiving a smaller portion of the money during the 2015–16 period. The five players declared free agents were pitcher César González, outfielder Albert Guaimaro, catcher Simon Muzziotti, and infielders Antonio Piñero and Eduardo Torrealba. As a result, they became free agents and were free to sign with other clubs, though each player will retain the initial bonus money he received from Boston. In addition, they will be required to hire new agents before they sign. As for the Red Sox, they will still be able to sign pool-exempt international players, but such players will be the only types of free agents able to be signed to contracts until next July 2, when the 2017–18 international signing period begins.^[93]
July 2 – The Cleveland Indians ended their franchise-record winning streak at 14 games with a 9–6 loss to the Toronto Blue Jays at Rogers Centre.^[94] Cleveland suffered its first loss since June 15 to the Kansas City Royals. Along the way, the Indians swept the Chicago White Sox, Tampa Bay Rays, Detroit Tigers and Atlanta Braves three times a piece, before taking the first two games from Toronto.^[95] The 14-game winning streak of the Indians was the longest in the American League since the Oakland Athletics won 20 consecutive games during the 2002 season. Josh Donaldson hit a go-ahead RBI single, as part of a three-run rally by Toronto in the bottom of the eight inning.^[94] Rajai Davis, who became the eighth Indians player to hit for the cycle, was also only the sixth player in MLB history to accomplish the feat in reverse fashion (home run first, then triple, double and single).^[96]
July 3 – Major League Baseball celebrates military appreciation day by staging a regular season game at Fort Bragg, North Carolina, the largest military base in the United States with more than 50,000 active duty personnel. The Florida Marlins defeat the Atlanta Braves, 5–2,^[97] in a temporary 12,500 seat ballpark with no paid admission, as all spectators are active servicemen and servicewomen and their families. It is the first professional contest of any sport to be played on an active U.S. military installation. Construction on the field began four months before the game, even though the ballpark will be torn down starting in a few days. Seating will be removed, but the playing surface, along with the foul poles, dugouts and bullpens will remain, because there are plans to convert the site into softball and multipurpose recreational facilities for use of those on the base.^[98]
July 6 – David Ortiz hit his 20th home run of the season, a two-run shot off Texas Rangers pitcher Martín Pérez in an 11–6 Boston Red Sox win at Fenway Park. It was his 523rd career homer, which also joined him with Babe Ruth, Hank Aaron, Willie Mays, Barry Bonds and Alex Rodríguez, as the only players in MLB history to hit at least 20 homers in 15 straight seasons or more. Ortiz has hit over 20 home runs in each of his 14 seasons for the Red Sox and belted exactly 20 in his final year with the Minnesota Twins in 2002.^[99]
July 10 – In the All-Star Futures Game, Boston Red Sox prospect Yoan Moncada delivered an upper-deck, two-run home run off Arizona Diamondbacks prospect Anthony Banda, to give the World team 4–3 lead over the U.S. team in the eighth inning.^[100] After taking the lead, the World team scored seven more runs in the ninth to turn a close game into an 11–3 blowout at Petco Park. The 21-year-old Cuban Moncada, who earlier had singled, stolen a base and made a sharp defensive play, earned MVP honors in the Game, as the World team was able to end a six-game losing streak.^[101]
July 12 – The American League defeated the National League, 4–2, in the 87th All-Star Game played at Petco Park in San Diego, California. In the second inning, Eric Hosmer hit a solo home run and Salvador Pérez belted a two-run homer against their former Kansas City Royals teammate Johnny Cueto. Hosmer added an RBI-single in the third to earn MVP honors.^[102]
July 18 – The Minnesota Twins relieved Terry Ryan of his duties as the team's executive vice president and general manager, ending an association that lasted 44 years. The Twins entered the day with a 33–58 record, 21 games out of first place in the AL Central Division. Only the Atlanta Braves (32–60) has registered a worse record in the majors. Ryan, who joined the organization as a player in 1972, formed part of the Twins front office since 1986, serving as their general manager from 1994 through 2007, and again served in this capacity from 2011 until his dismissal. Assistant GM Rob Antony will replace Ryan on an interim basis.^[103]
July 20 – Hanley Ramírez belted three two-run home runs, in the Boston Red Sox 11–7 interleague play victory against the San Francisco Giants at Fenway Park. Ramirez hit his first two shots in the second and third innings as the Red Sox built an 8–0 lead. The Giants answered with seven straight runs in the next two innings, and cut Boston's lead to 8–7. After that, Ramírez made a crucial defensive play starting a double play in the sixth inning, when, with the bases loaded and nobody out, he fielded a grounder and got the out at first base, then threw home to force out the potential tying run. He later responded in the bottom of the sixth with his third blast as the Sox held on for the win, which completed a two-game sweep of the NL West leaders and pushed the Sox into first place in the AL East by a half-game over the Baltimore Orioles. The three homers and six RBI were career-game highs for Ramírez.^[104]
July 22 – Miguel Cabrera went 4-for-4, including a go-ahead two-RBI single in the seventh inning, as the Detroit Tigers beat the Chicago White Sox, 7–5, at U.S. Cellular Field. With his decisive hit, Cabrera put himself into the annals of Major League history, making him the eight player to reach both the 400 home run and 1,500 RBI milestone in the first 14 seasons of his playing career. The others are Alex Rodríguez, Manny Ramírez, Albert Pujols, Lou Gehrig, Jimmie Foxx, Jeff Bagwell and Hank Aaron, according to ESPN Stats & Information.^[105]
July 23 – Nelson Cruz hit his ninth career grand slam and had a three-run home run, and the Seattle Mariners matched a season high with 19 hits, in an easy 14–5 victory over the Toronto Blue Jays at Rogers Centre. Cruz blasted his slam off R. A. Dickey in the third inning, and hit his three-run drive against Drew Storen in the eighth for his 20th career multi-homer game. This is the second time in Cruz's career that he has had at least two homers and seven RBI, the other coming on September 7, 2014, while playing with the Baltimore Orioles, as he has also collected two eight-RBI games.^[106] ^[107]
July 29 – The Washington Nationals pulled off a historic triple play en route to a 4–1 victory against the San Francisco Giants at AT&T Park.^[108] It was the first-ever 3–5 triple play in Major League Baseball history as well as the first in franchise history, according to the SABR Database.^[109] The feat started in the bottom in the eighth inning, with the bases loaded, nobody out, and Brandon Crawford hit a line drive off pitcher Sammy Solis. The ball was caught by first baseman Ryan Zimmerman, who stepped on the base for the second out and then threw to Anthony Rendon at third base, in time to force Denard Span for the third out.^[110]

August

August 3 – Albert Pujols hit his 12th career walk-off home run, breaking a 6–6 tie and giving the Los Angeles Angels an 8–6 victory over the Oakland Athletics. His two-run homer also was his 20th career walk-off hit, which tied him with David Ortiz for the most of any hitter since the 2000 season and the third most since 1969 in Major League Baseball. Besides, Pujols tied with Babe Ruth, Jimmie Foxx, Mickey Mantle, Stan Musial, and Frank Robinson in second place for the most career walk-off home runs. The all-time, walk-off home run hitter is Jim Thome, who hit 13 in his Major League career.^[111]
August 5 – Cleveland Indians catching prospect Francisco Mejía hit a double in the first inning in a Class-A game against the Salem Red Sox, to extend his historic hitting streak to 47 consecutive games, the longest in Minor League Baseball in 62 years. Mejía gave the Lynchburg Hillcats a quick 3–0 lead, but Salem used a big surge to claim a 13–6 victory at Lewis-Gale Field. The streak is also the seventh longest in Minor League Baseball history and the longest in the modern era, which began in 1963. The MiLB hit streak record is 69, set by Joe Wilhoit in 1919, while Joe DiMaggio, whose Major League record hit streak of 56 games is being celebrated for its 75th anniversary this season, had a 61-game Minor League hit streak in 1933, the second-longest of all time.^[112]
August 7 – At Coors Field, Ichiro Suzuki becomes the 30th member of the 3,000 hit club. He collects the milestone hit, a triple off Chris Rusin, in the eighth inning of the Miami Marlins' 10–7 victory over the Colorado Rockies. Suzuki, who collected 1,278 hits while in Nippon Professional Baseball, becomes the second player to triple for his 3,000th Major League hit, Paul Molitor having done so in .^[113]
August 12 :
- Alex Rodriguez plays the final game of his 22-year major league career as the New York Yankees beat the Tampa Bay Rays, 6–3. Rodriguez's final MLB hit was an RBI double in the first inning that tied the game at 1 while Starlin Castro delivered a game-winning 2-run home run in the 6th inning to power the Yankees to victory.^[114]
- Hanley Ramírez hit a pair of three-run home runs and David Ortiz went 3-for-4 with one double and a solo homer, as the Boston Red Sox beat the Arizona Diamondbacks, 9–4, in interleague play at Fenway Park.^[115] For his part, Ramírez recorded his 20th career multi-homer game and matched his career high with six runs batted in,^[115] while Ortiz, with his home run, reached 1,000 extra-base hits and became the third player – along with Carl Yastrzemski (1,157) and Ted Williams (1,117) – to record 1,000 extra base hits in a Red Sox uniform.^[116]
August 13 – New York Yankees prospects Tyler Austin and Aaron Judge hit back-to-back home runs in their first career at bat, as the Yankees defeated the Tampa Bay Rays, 8–4, at Yankee Stadium. Austin and Judge belted their homers against pitcher Matt Andriese in the second inning. It is the first time in Major League Baseball history that a pair of teammates hit consecutive home runs in their first career plate appearances.^[117] The feat was accomplished once before by opponents, when Heinie Mueller of the Philadelphia Phillies and Ernie Koy of the Brooklyn Dodgers each hit a home run in their first major league at-bats on April 19, 1938.^[118]
August 14 :
- The New York Yankees honored Mariano Rivera before their series finale against the Tampa Bay Rays at Yankee Stadium, officially dedicating a Monument Park plaque to the all-time saves leader and future Hall of Fame closer in a pregame ceremony. Rivera accepted his plaque and spoke at the Stadium, giving credit to the fans and everyone who helped during his 19-year career. Rivera was also joined on the field by his family, former teammates David Cone, Derek Jeter, Tino Martinez, Paul O'Neill, Andy Pettitte, Jorge Posada and John Wetteland, as well as his former managers Joe Torre and Joe Girardi, his former pitching coach, Mel Stottlemyre, and the Yankees former trainer, Gene Monahan.^[119]
- Mookie Betts hit three home runs over the Green Monster and posted a career-high eight RBI, as the Boston Red Sox crushed the Arizona Diamondbacks, 16–3, to sweep the three-game interleague series.^[120] Dustin Pedroia, meanwhile, recorded his franchise-record fifth five-hit game and Rick Porcello converted into the first Red Sox pitcher in 70 years to open a season 12–0 at Fenway Park, since Dave Ferriss won his first 12 decisions at Fenway in 1946.^[120] Additionally, Betts became the 21st player in Major League Baseball history to hit three home runs in a single game twice in the same season.^[121] He also joined Ted Williams as the only Red Sox hitters ever to accomplish the feat. Williams did it in 1957,^[121] while Betts blasted three homers against the Baltimore Orioles at Camden Yards on May 31.
- High Class-A Lynchburg Hillcats catcher Francisco Mejía halted his hitting streak at 50 games. A day after a controversial scoring change enabled Mejía to tie for the fourth-longest run in Minor League history,^[122] the Cleveland Indians No. 3 prospect went 0-for-3 with a walk and an RBI in a 6–0 shutout over the Winston-Salem Dash (CWS) at Calvin Falwell Field. It is the longest hitting streak since the Minor Leagues reclassified in 1963, and it's the longest by any player at any level since Román Mejías hit safely in 55 straight games for the Class-B Waco Pirates in 1954. Joe Wilhoit holds the record with 69 games (1919) and Joe DiMaggio is second with 55 games (1933).^[123]
August 15 – Mookie Betts belted two home runs, a three-run homer in the fifth inning to put the Boston Red Sox ahead, 3–0, and a two-shot in the eighth, accounting for all five Red Sox runs in a 5–3 win over the Baltimore Orioles at Camden Yards. Sox starter Eduardo Rodríguez departed with no outs in the fifth-inning of a no-hitter due to a tight left hamstring and, while Matt Barnes carried the no-hitter into the seventh, a combination of three relievers allowed three runs in the inning to tie the game.^[124]
August 19 – The Houston Astros defeated the Baltimore Orioles, 15–8, in a slugfest at Camden Yards. At the end, both teams combined for nine home runs. George Springer got things started, leading off the game with a home run off pitcher Wade Miley. But the Orioles set a modern Major League record by hitting four home runs before making an out in their first turn at-bat. Facing Collin McHugh, Adam Jones hit a home run on the first pitch he saw and Hyun Soo Kim delivered a single. Then Manny Machado, Chris Davis and Mark Trumbo all homered in succession, for a quick 5–1 lead. Nevertheless, the Astros scored five runs in the second inning, when José Altuve roped a two-out, two-run double, and kept going from there to win the game. After the teams traded five-run innings, Baltimore went up 7–6 in the third and Houston pulled even in the fourth and took a 9–7 lead in the fifth. Pedro Álvarez hit a solo shot in the bottom half before Houston pulled away with three runs in the sixth, thanks to a two-run homer by Altuve and a solo shot by Evan Gattis. Houston added three more runs the rest of the way, highlighted by a homer from Teoscar Hernández in the ninth. According to STATS LLC, the Orioles became the first team in the modern era (since 1900) to open a game with four home runs before making an out.^[125]
August 22 – Baltimore Orioles closer Zach Britton ended his remarkable streak of 43 consecutive games without allowing an earned run, but was able to hold off a late ninth-inning rally by the Washington Nationals to help Baltimore edge the host Nationals 10–8. Britton gave up a single to Bryce Harper and an RBI double to Anthony Rendon, but got Ryan Zimmerman to ground into a game-ending double play as the Orioles won its third game in a row against Washington.^[126] It was the first earned run Britton allowed since April 30. His string of 43 pitching appearances without allowing one is the longest since the earned run statistic became official, dating back more than 100 years.^[127]
August 24 – Boston Red Sox designated hitter David Ortiz reached a new milestone in his career, while hitting a two-run, home run against Tampa Bay Rays starter Matt Andriese in the first inning of a 4–3, 11-inning loss to the Rays at Tropicana Field. With the two-run blast, Ortiz recorded his 100th run batted in of the season and became the oldest player in Major League Baseball history to hit 30 homers in a single season, having managed the feat at 40 years and 280 days old. The two RBI also allowed Ortiz to join Hank Aaron, Barry Bonds, Jimmie Foxx, Lou Gehrig, Rafael Palmeiro, Albert Pujols, Manny Ramírez, Alex Rodríguez and Babe Ruth, as the only players with 10 or more MLB seasons with at least 30 homers and 100 RBI, which is also the most in Red Sox history. As far as the aforementioned players are concerned, Ortiz joined Aaron, Gehrig, Pujols and Ruth as the only ones to do it with the same team. Ortiz, who will retire at the end of the season, is additionally the first player to achieve the 30-HR, 100-RBI feat in his last MLB season.^[128] ^[129]
August 25 – At Dodger Stadium, Matt Moore of the San Francisco Giants has a no-hitter broken up with two out in the ninth in a 4–0 victory over the Los Angeles Dodgers. A single by the Dodgers' Corey Seager breaks up the bid, after which Moore, who records his first victory as a Giant after being traded from the Tampa Bay Rays at the trading deadline, is relieved by Santiago Casilla, who needs only one pitch to record the final out. The no-hitter would have given the Giants at least one in a record five consecutive seasons. Matt Cain had pitched a perfect game in, followed by Tim Lincecum's two no-hitters in the and seasons, and Chris Heston's in . They had entered the season tied with the – Los Angeles Dodgers with no-hitters pitched in four consecutive seasons; Sandy Koufax had pitched all four, the last of which was his perfect game in 1965. The Moore no-hitter also would have been the first by a Giants pitcher against the Dodgers since Rube Marquard, of the then New York Giants, no-hit the Brooklyn Dodgers in .^[130]

September

September 3 – Mike Trout, Albert Pujols and Kole Calhoun combined for five home runs to lead the Angels to a 10–3 victory over the host Seattle Mariners, with the trio hitting consecutive shots against Taijuan Walker in the first inning, and Calhoun and Pujols belting two homers apiece. For Pujols, it was his 587th career home run, which moved him past Frank Robinson into ninth place on the MLB's most home runs list. He later blasted his No. 588, completing the 55 multi-homer game of his career. Next up on the career home run list for Pujols is Sammy Sosa, who ranks eighth with 609 homers.^[131]
September 6 – The St. Louis Cardinals hit five home runs, three of them in the ninth inning, to defeat the Pittsburgh Pirates at PNC Park. Matt Carpenter connected a pinch-hit, solo home run to tie the game 6–6, while Randal Grichuk and Jhonny Peralta homered later in the inning, as the Cardinals went on to win 9–7. Carpenter's pinch-hit shot gave the Cardinals a Major League record 15 pinch-hit homers in a season. The previous record of 14 pinch-hit home runs was held jointly by the San Francisco Giants and the Arizona Diamondbacks in the 2001 season. Yadier Molina and Matt Adams homered early in the game, to give the Cardinals a National league lead with 201 homers in the season, a second-best behind the American League leaders Baltimore Orioles (218). Additionally, the Cardinals tied the National League record for most consecutive games with at least one home run at 25. The Major League record is held by the Texas Rangers, who homered in 27 straight games in 2002.^[132] ^[133]
September 7 – The New York Mets sign former Heisman Trophy winner and NFL quarterback Tim Tebow to a minor league contract. At age 29, Tebow is slated to begin his professional baseball career in the fall Florida Instructional League on September 19.^[134]

Austin, who hit a home run in his first at-bat on August 13, belted his second career homer on his 25th birthday, two days before, and gave the Yankees the lead in a win against the Toronto Blue Jays. According to the Elias Sports Bureau, Austin is the first player in the modern era to hit a home run in his first at-bat, hit a home run on his birthday, and hit a walk-off home run within the first three home runs of his Major League career.^[136]
September 10 – Los Angeles Dodgers pitcher Rich Hill hurled seven perfect innings against the host Miami Marlins, but was pulled by Dodgers manager Dave Roberts because of concern over a previous blister problem that caused Hill to miss significant time during the season. Hill had thrown 89 pitches and struck out nine before being replaced by Joe Blanton in the eight. But after two outs, Blanton allowed a single to Jeff Francoeur. Then, in the ninth, Dee Gordon added another single with two outs, as the Dodgers finally prevailed, 5–0. In the seventh, left fielder Yasiel Puig made an outstanding diving catch for the third out, depriving Martín Prado of a likely extra-base hit while preserving the perfect game for Hill.^[137] It is the second time Roberts removes a pitcher with a no-hitter bid going late in a game, having done the same to rookie Ross Stripling back on April 8. By then, Stripling had thrown 100 pitches and innings in his Major League debut, a game the Dodgers finally lost to the San Francisco Giants at AT&T Park, 3–2, in 10 innings.^[138]
September 11 – David Ortiz blasted a three-run home run against Joaquin Benoit in the sixth inning, as the Boston Red Sox went on to win the Toronto Blue Jays at Rogers Centre, 11–8, that restored their two-game lead in the American League East.^[139] The Red Sox had already blown two early leads and were now facing an 8–7 deficit.^[139] For Ortiz, it was his career 535 home run, moving him ahead of Jimmie Foxx into sole possession of 18th place on the MLB all-time home run list, and is now one homer behind Mickey Mantle for 17th in the list.^[139] It also brought back memories from the past, when Ortiz slugged a grand slam off Benoit,^[139] then with the Detroit Tigers, during the eighth inning of Game 2 of the 2013 ALCS with Boston in a 5–1 hole. The Red Sox won the game, 6–5, tied the series, and ended winning the AL championship in six games, en route to the 2013 World Series title. Heading into his 123rd and final regular season game ever at Rogers Centre,^[140] Ortiz already extended his own records for most career homers (41), runs batted in (108) and extra-base hits (76) for a visiting player.^[140] Ortiz also increased his RBI total to 110 in the season, the most by a player aged 40 or above since Dave Winfield had 108 for Toronto in 1992.^[139]
September 12 :
- Chicago Cubs pitcher Kyle Hendricks took a no-hitter bid into the ninth inning in a start against the St. Louis Cardinals at Busch Stadium, but Jeremy Hazelbaker led off the frame with a home run to break it up. Still, Hendricks earned his 15th victory of the season, 4–1, and lowered his ERA to 2.03, the best in Major League Baseball.^[141]
- David Ortiz hit his 536th career home run at Fenway Park to tie Mickey Mantle for 17th place on the MLB all-time home run list, as the Boston Red Sox crushed the Baltimore Orioles, 12–2, to maintain a two-game lead over the Toronto Blue Jays in the AL East Division. David Price improved his season record to 16–8, allowing two runs on two hits without walks, while striking out nine in eight innings for his seventh victory in as many starts to set the longest winning streak of his career.^[142]
September 14 – The Toronto Blue Jays announced the hiring of former Boston Red Sox general manager Ben Cherington as their new vice president of baseball operations. Cherington, who guided the Red Sox to the 2013 World Series title, left the organization after Dave Dombrowski was hired as president of baseball operations in August 2015. Since then, Dombrowski credited Cherington for helping to develop a talented group of young players for the Sox, including Mookie Betts, Xander Bogaerts, Jackie Bradley Jr. and Andrew Benintendi, among others. Cherington started his career as an advance scout for the Cleveland Indians in 1998, when Mark Shapiro worked as assistant general manager of the Indians. Shapiro joined the Blue Jays as their new president and chief executive officer (CEO) at the end of the 2015 season.^[143]
September 15 :
- The Chicago Cubs wasted its first chance to clinch the NL Central Division title after Scooter Gennett hit a two-run double in the seventh inning that lifted the Milwaukee Brewers to a 5–4 win at Wrigley Field. Nevertheless, the Cubs became the Major League first team to clinch their division, when the St. Louis Cardinals lost to the San Francisco Giants, 6–2, late at night. It was the first NLCD title for the Cubs since 2008, as well as its fourth overall.^[144]
- Hanley Ramírez hit a two-out, three-run walk-off home run off Dellin Betances in the bottom of the ninth inning, to finish off a five-run rally that gave the Boston Red Sox a 7–5 victory over the New York Yankees at Fenway Park. Boston was down, 5–1, before David Ortiz ripped a solo home run in the eighth for his career homer No. 537, which put him ahead of Mickey Mantle for 17th place on MLB all-time home run list. Both homers were mammoth shots to center field. Ramirez's homer was projected at 441 feet while Ortiz's shot had a projected distance of 442 feet, according to STATS LLC.^[145] ^[146]
- Major League Baseball announced that San Diego Padres general manager A. J. Preller was suspended for 30 days without pay for submitting false medical records in the trade that sent Drew Pomeranz to the Boston Red Sox in exchange for top prospect Anderson Espinoza earlier this season. This is not the first time that Preller has been reprimanded by MLB. In 2010, Preller was suspended while serving as an assistant general manager for the Texas Rangers. That case involved the international signing rules, for negotiating and presenting a false age for Rafael De Paula, an amateur pitcher from the Dominican Republic. De Paula was also suspended and the Rangers fined.^[147] ^[148]
September 17 – Colorado Rockies pitcher Jon Gray set a team record by striking out 16 batters in a four-hit, complete game shutout over the San Diego Padres at Coors Field. Gray etched his name into the Rockies' book in surpassing the previous 14-strikeout performance of Darryl Kile, set on August 28, 1998. Gray also became the second Rockies pitcher to strike four batters in an inning, doing so in the second frame on a passed ball, and posted another team mark with six consecutive strikeouts.^[149]
September 18 :
- The Detroit Tigers defeated the Cleveland Indians, 9–5, while Miguel Cabrera collected his 2,500th career hit. Cabrera, a two-time American League MVP and triple crown winner, became the 100th player in Major League history to reach the milestone with his single off Indians starter Trevor Bauer in the third inning. Besides, the Venezuelan slugger also became the eighth player to do so by his age-33 season. The others on that short list include Hank Aaron, Ty Cobb, Jimmie Foxx, Rogers Hornsby, Mel Ott, Alex Rodriguez and Robin Yount. According to the Elias Sports Bureau, Cabrera is the youngest to reach the 2,500 hits mark since Aaron did it in 1967.^[150]
- Hanley Ramírez hit two home runs and drove in four runs, to give the Boston Red Sox a 5–4 victory over the New York Yankees, while completing a four-game sweep at Fenway Park. The Yankees took a 4–0 lead in the fifth inning, but for the third time in four days, they were unable to lock it down. In the bottom of the frame, Ramírez belted a two-out, three-run homer off CC Sabathia and Jackie Bradley Jr. tied the score with an RBI single in the sixth on what wound up being the 112th and final pitch of the game for Sabathia. Then in the seventh, Ramírez hit his second homer of the game and fourth of the series against reliever Tyler Clippard that snapped the 4–4 tie, as the Red Sox swept a four-game series from the Yankees for the first time since June 4–7, 1990.^[151]
September 20- Marlins pitcher Jose Fernandez strikes out 12 batters, allowing 3 hits and no walks in a 1–0 victory over the division-leading Washington Nationals. This was the final game of Fernandez's career as he is killed in a boating accident 5 days later.
September 22 - Brian Dozier made history in the Minnesota Twins 9–2 loss to the Detroit Tigers at Target Field, as he blasted his 42nd home run of the season and his 40th while playing second base, which set a new American League single-season record for homers hit by a second baseman.^[152] Alfonso Soriano held the previously AL record for a second baseman with 39 homers while playing for the New York Yankees in the 2002 season. The Major League Baseball season record for a second baseman is shared by Rogers Hornsby, who connected 42 homers for the St. Louis Cardinals in 1922, and Davey Johnson, who slugged 42 homers for the 1973 Atlanta Braves.^[153]
September 23 :
- The Texas Rangers secured their second consecutive American League West Division title, becoming the first AL team to reach the playoffs with a 3–0 win against the host Oakland Athletics. This is the seventh ALWD title for the Rangers, and fourth since the 2010 season.^[154]
- David Ortiz hit a 411-foot home run to right field in the first inning that supplied the necessary runs in the Boston Red Sox' 2–1 victory over the Tampa Bay Rays at Tropicana Field.^[155] Ortiz, who will retire at the end of the season, delivered his shot against starter Chris Archer and raised his runs batted in total to 124, one more than Shoeless Joe Jackson collected in his final season of 1920, when the RBI became an official statistic.^[155] It was the 37th home run for Ortiz in his farewell season. Three days previously, he had passed Dave Kingman for the most homers ever by a major league player in his final season. In 1986, Kingman hit 35 homers for the Oakland Athletics.^[155] This homer also tied Ortiz with Hall of Famer Lou Gehrig for the 10th most career extra-base hits (1,190).^[156] In addition, Ortiz hit a single in the seventh inning for his 2,465 career hit, putting him one hit shy of tying another Hall of Famer, Harry Hooper, for the 109th place on the all-time list.^[157]
September 24 – The Washington Nationals defeated the visiting Pittsburgh Pirates, 6–1.

Boston made history when their pitchers set a team record with 23 strikeouts, including a major league record of 11 in a row. The 23 strikeouts overall were the most in a 10-inning game since at least 1913 and the most in a game of any length since 2004. Starter Eduardo Rodríguez had a career-high 13 strikeouts through innings, including the final six batters he faced. Rodríguez was relieved by Heath Hembree, who struck out all five Rays he saw in innings.^[161] The New York Mets held the previous mark when Tom Seaver struck out 10 in a row against the San Diego Padres on April 22, 1970.^[162] Matt Barnes did strike out one and Joe Kelly fanned four to complete the feat. Dustin Pedroia, who sealed the previous game with a grand slam, hit a solo home run in the third inning and aggressively scored the winning run with an RBI-double by David Ortiz in the tenth. The relay throw from outfield beat Pedroia to the home plate, but he avoided catcher Luke Maile's first tag and past the plate. Then Pedroia went back to touch it and Maile was charged with an error when the ball dropped out of his glove on another tag attempt. Meanwhile, Mookie Betts extended his hitting streak to 11 games with an RBI single in the first. The Red Sox' one-run lead disappeared in the eighth inning when Fernando Abad allowed an RBI single to Brad Miller, but Kelly was able to come on and induced a 4–6–3 double play to end the eighth.

Furthermore, Jaso became just the second catcher in Major League Baseball history to hit a cycle and catch a perfect game, joining Hall of Famer Ray Schalk, who caught the Charlie Robertson's perfecto in 1922 while playing for the Chicago White Sox. Jaso did so for the Seattle Mariners, along with Félix Hernández in 2012.^[166]
September 29 :
- The Chicago Cubs announced that president of baseball operations Theo Epstein was signed a five-year contract extension that will run from 2017 through 2021. The Cubs also gave extensions to general manager Jed Hoyer and vice president of amateur scouting and player development Jason McLeod. Epstein, 42, resigned as general manager of the Boston Red Sox to join the Cubs in October 2011. While the early stages of his tenure were mired with losing clubs, the Cubs were transformed from a mediocre cellar dweller team to a powerhouse that has posted the best record in Major League Baseball this season after finishing with 97 wins a year ago.^[167]
- For the first time since the 2005 season, a Major League Baseball game ends in a tie as rain stops the final scheduled contest of the year between the Chicago Cubs and the Pittsburgh Pirates in the sixth inning with the score tied at 1–1. The game will not be resumed as its result has no bearing on the postseason results. Instead of becoming a suspended game, the statistics count and it was declared a tie, the first since the Houston Astros and Cincinnati Reds went seven innings on June 30, 2005, before rain halted them.^[168]
September 30 – The Cincinnati Reds announced that Bryan Price will return as the team's manager for the 2017 season. His new deal includes a club option for 2018.

October

October 1 – The New York Mets beat the Philadelphia Phillies, 5–3, and secured a berth in the postseason, qualifying for the playoffs in consecutive seasons for just the second time in franchise history. As the No. 1 seed in the National League wild card game, they will host the No. 2 seed on October 5 at Citi Field. The Mets last reached consecutive postseasons in 1999 and 2000, both times as the wild-card entry.^[170]
October 2 – The Baltimore Orioles beat the New York Yankees, 5–2, to clinch an American League Wild Card spot, while the Toronto Blue Jays assured a berth in the postseason when the Detroit Tigers lost to the Atlanta Braves 1–0. Later, Toronto defeated the Boston Red Sox, 2–1, to earn the No. 1 wild-card spot and will host the Orioles on October 4. The winner move on to face the Texas Rangers in the AL Division Series. Furthermore, the San Francisco Giants were the last National League team to reach the playoffs, securing the second NL wild card with a 7–1 win over the Los Angeles Dodgers, during what turned out to be the last game behind the mike for legendary Hall of Fame broadcaster Vin Scully. San Francisco, which won World Series titles between 2010 and 2014, plays at the defending NL champion New York Mets on October 4 in the NL wild-card game, with the winner advancing to the NL Division Series against the Chicago Cubs.^[171]
October 3 :
- The Chicago White Sox named Rick Renteria as the 40th field manager in club history, replacing Robin Ventura, who managed the Sox during the last five seasons. Renteria served as bench coach under Ventura this past season and previously managed the Cubs in 2014,^[172] joining Johnny Evers as the only people in the history of the Chicago franchises to manage both.^[173] Besides, Renteria spent six seasons on the San Diego Padres' coaching staff, including 2011–2013 as their bench coach and 2008–2010 coaching at first base. In between, he managed the Mexico Team in the 2013 World Baseball Classic.^[172]
- Walt Weiss resigned as Colorado Rockies manager after four seasons at the helm, even though his departure was not entirely unexpected, as he was in the last year of a three-year contract and there were no negotiations to extend that during the season. Weiss posted a 283–365 record in his four-year managing tenure and never had a winning season. An All-Star shortstop and Rookie of Year Award winner, he played for four teams in 14 seasons spanning 1987–2000, four of them with the Rockies in the mid-1990s, including their wild card-winning season of 1995. Weiss later served in the organization as a special assistant to the general manager for seven years from 2002 to 2008.^[174]
- Coming off another disappointing season, the Arizona Diamondbacks announced that general manager Dave Stewart and field manager Chip Hale will not be back in 2017, as Stewart was told his contract would not be renewed and Hale was dismissed. The role of chief baseball officer Tony La Russa had not been resolved. Arizona finished with a 69–93 record in 2016, 22 games out of first place, and missed the playoffs again. La Russa was hired in May 2014 to oversee the baseball operations department and he spent the rest of that season evaluating the organization. As a result, La Russa dismissed GM Kevin Towers and manager Kirk Gibson in September that year and then hired Stewart and Hale to replace them. The Diamondbacks clinched the 2001 World Series and won three National League west division titles between 2002 and 2011, but the team has been in a steady decline since then, posting five consecutive non-winning seasons.^[175]
October 4 – Edwin Encarnación hit a three-run home run in the bottom of the 11th inning at Rogers Centre, to send the Toronto Blue Jays to a 5–2 victory over the Baltimore Orioles in the American League Wild Card Game. Toronto now advances to the AL Division Series for a best-of-five rematch against the Texas Rangers at Globe Life Park in Arlington.

October 5 – The San Francisco Giants defeated the New York Mets, 3–0, behind the pitching of Madison Bumgarner and a three-run home run from Conor Gillaspie off reliever Jeurys Familia in the ninth inning, to win the National League Wild Card Game at Citi Field. With their victory, the Giants advanced to face the heavily favored host Chicago Cubs in the best-of-five NL Division Series beginning on October 7. Bumgarner, who allowed four hits with two walks and struck out six in his third career postseason shutout, completed 23 consecutive innings pitched in the postseason without giving up a run, setting a new MLB record. In a losing effort, Mets starter Noah Syndergaard carried a no-hitter with two outs into the sixth inning before taking a no-decision after seven shutout frames and 10 strikeouts.^[177]
October 6 :
- Troy Tulowitzki hit a bases-loaded triple that capped a five-run third inning and Marco Estrada pitched a gem as the Toronto Blue Jays crushed the host Texas Rangers, 10–1, in Game 1 of the American League Division Series.

Roberto Pérez, Jason Kipnis and Francisco Lindor homered in a four-batter, nine-pitch span, which marked the first time the Indians achieved the feat in a postseason game since Manny Ramírez, Jim Thome and Mark Whiten did it against Andy Pettitte in the 1998 American League Championship Series. Andrew Miller worked two shutout innings of relief for Cleveland starter Trevor Bauer and was credited with the win.^[179] ^[180]
October 7 :
- The Toronto Blue Jays smashed four home runs to take a 5–3 victory over the Texas Rangers in Game 2 of the American League Division Series. All four homers came off Texas starter Yu Darvish, which provided the Blue Jays with a 2–0 lead in the best-of-five format and pushed the Rangers to the brink of elimination. For Troy Tulowitzki, who delivered the big hit for Toronto with a bases-loaded triple in Game 1, his two-run shot in the top of the second inning was his fourth career postseason home run. The Blue Jays then broke the game wide open in the fifth with three solo homers from Kevin Pillar, Edwin Encarnación and Ezequiel Carrera. Toronto starter J. A. Happ pitched five-plus innings and allowed just one run. He scattered nine hits and had five strikeouts with a walk, while closer Roberto Osuna came from the bullpen for a five-out save. Now the series moves to Toronto's Rogers Centre, where a win will propel Canada's team into a second consecutive AL Championship Series.^[181]
- Cleveland Indians starter Corey Kluber pitched seventh scoreless innings to set up a 6–0 home win against the Boston Red Sox. Showing no signs of a late-season groin tightness,^[182] Kluber allowed only three singles along with seven strikeouts and three walks. After that, Dan Otero and Bryan Shaw combined for two perfect-innings of relief, which moved the Indians to within one win of a place in the American League Championship Series for the first time in nine years. For his part, Lonnie Chisenhall connected for a three-run home run in the second inning off Boston starter David Price, who fell to a 0–8 record with a 5.74 earned run average in nine career playoff starts. Price lasted just innings, allowing five runs on six hits in only 65 pitches, as the Red Sox fell into a 2–0 deficit in the series and will face elimination in Game 3 at Fenway Park.^[183]
- Los Angeles Dodgers pitching ace Clayton Kershaw was not at his best form but did enough to lead the Dodgers to a 4–3 win over the host Washington Nationals in Game 1 of the National League Division Series. Kershaw, who was backed by early home runs from Corey Seager and Justin Turner, gave up an uncharacteristic eight hits but did strike out seven and walked one in his five innings of work, throwing 101 pitches in the process. At the beginning, Kershaw had a 4–0 lead in the bottom of the third inning but gave up a two-run, RBI single to Anthony Rendon, followed by an RBI sacrifice fly from Trea Turner in the fourth to cut the Nationals' deficit to 4–3. Then four Dodgers relievers combined to pitch four scoreless innings and close out the game.

- The Chicago Cubs–San Francisco Game 1 of the National League Division Series was a classic pitchers' duel between Cubs' Jon Lester and Giants' Johnny Cueto, with the game scoreless into the bottom of the eighth inning at Wrigley Field. Cubs second baseman Javier Báez supplied the only run of the game with a solo home run that just made it to the restricted basket above the left field wall. As a result, the run ended the Giants record of not giving up a run in 23 innings of postseason play, dating back to the 2014 World Series. Lester spaced six hits and strike out six batters without allowing a walk, guiding the Cubs to a 1–0 record in the best-of-five NL Division Series. In the ninth, Cubs closer Aroldis Chapman allowed a two-out double to Buster Posey in the ninth, before retiring Hunter Pence on a ground out to Báez for the final out of the game. Cueto was the hard luck loser as he went the distance for San Francisco, allowing only three hits and striking out ten while walking none.^[185]

- The Chicago Cubs beat the San Francisco Giants, 5–2, taking a 2–0 advantage in the best-of-five National League Division Series in front of a sellout crowd of 42,392 at Wrigley Field.

Hendricks was replaced by Travis Wood, who retired the last out of the inning and then in the bottom half hit a home run off George Kontos to the left field bleachers. It was the first home run by a relief pitcher in the postseason since New York Giants' Rosy Ryan hit one in Game 3 of the 1924 World Series. Moreover, Wood joined Rick Sutcliffe (1984 NLCS) and Kerry Wood (2003 NLCS) as the only Cubs pitchers to hit a home run in the playoffs.

Nationals starter Tanner Roark allowed two runs and seven hits in just innings, but five relievers combined to shut out Los Angeles for the final innings. The light-hitting and rarely used Lobatón, who is playing as a replacement for injured All-Star catcher Wilson Ramos, became an unlikely hero in the rain-postponed game when his shot served to erase an early deficit and evened the best-of-five series at one-all. Blake Treinen was credited with the win while Mark Melancon earned the save. Dodgers starter Rich Hill gave up four runs and six hits in innings and was charged with the loss. The series will resume on Monday 10 at Dodger Stadium.^[188]

Both teams then traded zeroes until the top of the ninth, when Wertz delivered his solo shot and Ryan Zimmerman added a two-run RBI double. Zimmerman then scored an insurance run on a sacrifice fly RBI from Chris Heisey. Nationals starter Gio González allowed all three runs by the Dodgers in innings, but four relievers preserved the rest of the way, with Sammy Solis being credited with the win. The losing pitcher was Kenta Maeda, who lasted just three innings while allowing four runs on five hits and two walks alongside four strikeouts.

On the other hand, Josh Tomlin pitched five strong innings of four-hit ball and two runs for Cleveland. He then was backed by relievers Andrew Miller and Bryan Shaw, while closer Cody Allen got four outs as the Indians advanced the AL Championship Series for the first time since 2007. Red Sox designated hitter David Ortiz collected an RBI sacrifice fly in before walking on four pitches during his final career plate appearance in the eight inning. Through 14 seasons of top notch ranking, Ortiz guided the Red Sox to its first three World Series titles since their 1918 season. Ten minutes after the final out, when most of Cleveland's players had moved the field celebration into the visitors' clubhouse, the Boston faithful demanded to see Ortiz one more time. Chants of "We're not leaving!" and "Thank you, Papi!" finally drew Ortiz back onto the field, where he lumbered out to the pitching mound and tipped his cap in all directions. The Indians advanced to the AL Championship Series for the first time since 2007, when they beat the New York Yankees in the ALDS and then wasted a 3–1 lead over the Red Sox in the ALCS. As a home club, Cleveland will wait for the Toronto Blue Jays to open the best-of-seven championship series on October 14.^[192]
- Joe Panik doubled Brandon Crawford with the winning run to snap a tie in the bottom of the 13th inning, sending the San Francisco Giants to a 6–5 victory over the Chicago Cubs in Game 3 of the National League Division Series at AT&T Park.

October 11 :
- Chase Utley delivered a tie-breaking RBI single with two outs in the eighth inning to give the Los Angeles Dodgers a 6–5 victory over the Washington Nationals at Dodger Stadium.

The Dodgers held a 4–2 lead after three innings and 5–2 after five, when the Nationals loaded the bases against Los Angeles starter Clayton Kershaw with two outs in the top of the seventh. Kershaw was removed after throwing 110 pitches, being replaced with Pedro Báez, who promptly hit Jayson Werth with his first pitch, before Daniel Murphy followed with a two-run single off Luis Avilán to tie the score at 5–5. Kershaw, who was pitching on three days' rest for the fourth consecutive postseason, struck out 11 but was charged with five runs on seven hits and two walks in innings of work.

- Javier Báez slashed an RBI single that capped a four-run rally in the top of the ninth inning to lead the Chicago Cubs to a 6–5 victory over the San Francisco Giants at AT&T Park and a 3–1 National League Division Series win. As a result, the Cubs uprising against five San Francisco relievers denied the Giants an 11th consecutive win in an elimination game, which would have extended their own MLB record. Giants starter Matt Moore limited the Cubs to two runs and two hits over eight innings and Conor Gillaspie went 4-for-4 in an 11-hit effort, as the Giants were three outs away from forcing a fifth and deciding game when they took a 5–2 lead into the ninth. But Ben Zobrist hit an RBI double and Willson Contreras contributed with a two-run, game-tying RBI single with none out, before Báez singled in the go-ahead run two batters later. Cubs starter John Lackey allowed four runs in four innings and Héctor Rondón, who worked a scoreless eighth inning, was credited with the win. Rondón was followed by closer Aroldis Chapman, who blew a save in the 13-inning loss the previous game, but now earned his third save of the series by striking out the side in the ninth, sending his team into the next round. Giants reliever Will Smith was charged with the loss, even though the run off him was unearned. Next up for the Cubs will be Game 1 of the National League Championship Series, set for Saturday 15 at Wrigley Field against either the Washington Nationals or Los Angeles Dodgers.^[195]
