The 2018 Seattle Mariners season was the 42nd season in franchise history. The Mariners played their 19th full season (20th overall) at Safeco Field, their home ballpark. After the Buffalo Bills of the NFL clinched a playoffs spot for the first time since 1999, The Mariners entered this season with the longest active playoff drought in the four major North American professional sports, failing to make their first postseason appearance since 2001. At several points in the season, the Mariners were 10 games ahead of the Oakland Athletics in the AL Wild Card race, but ended up finishing eight games behind them. The Mariners were eliminated from playoff contention on September 22 with the Athletics win against the Minnesota Twins. The Mariners began the season on March 29, 2018 against the Cleveland Indians and finished the season on September 30 against the Texas Rangers.
The Mariners were led by manager Scott Servais in his third year as manager.
On December 7, 2017, the Mariners traded three minor leaguers to the Miami Marlins for Dee Gordon and $1 million in international slot money. General manager Jerry Dipoto stated he planned to use Gordon in center field instead of his usual second base.[1]
On March 6, 2018, the Mariners signed free agent Ichiro Suzuki for a $750k salary with incentives up to $2M. He returned to the Seattle Mariners after five years being with the New York Yankees and the Miami Marlins, respectively.
