Major League Baseball (MLB) uses instant replay review to allow league officials to review certain types of plays in order to determine the accuracy of the initial call of the umpires on the field. Reviews may be initiated either by a team's manager with limitations or by the umpires themselves. All instant replay reviews are examined by umpires at the Replay Command Center in New York City, who have the final decision as to whether to uphold or overturn the initial call.
In a Major League Baseball game played on June 2, 2010, at Detroit's Comerica Park, Detroit Tigers pitcher Armando Galarraga nearly became the 21st pitcher in Major League Baseball history to throw a perfect game. Facing the Cleveland Indians, Galarraga retired the first 26 batters he faced. His bid for a perfect game was ruined one out short when first-base umpire Jim Joyce incorrectly ruled that Indians batter Jason Donald reached first base safely on a ground ball. Galarraga instead finished with a one-hit shutout in a 3–0 victory. He faced 28 batters and threw 88 pitches, striking out three. The game is sometimes referred to as the "28-out perfect game", the "almost perfect game", the "extra perfect game", the "imperfect game", or simply the "Galarraga game".
