William Joseph "Barry" McCormick (December 25, 1874January 28, 1956) was a professional baseball player and later a Major League umpire.
As a player, he played infielder in Major League Baseball from 1895 to 1904. He would play for the Louisville Colonels, Chicago Colts/Orphans, St. Louis Browns, and Washington Senators. McCormick was the last player to have eight at-bats in a nine-inning game, achieving this feat on the 29th of June, 1897.[1]
After retiring as a player, he took up umpiring, making his Major League debut in 1917 and winding up his second career in 1929.[2] He was behind the plate for the longest extra inning game in Major League history, the 26-inning contest between the Brooklyn Dodgers and Boston Braves on May 1, 1920.
