Events

 * May 8 – Philadelphia Athletics manager Connie Mack needed a substitute outfielder in the sixth inning of a game against the Boston Americans and called on pitcher Chief Bender to fill in. Bender hit two home runs, both inside the park.
 * May 17 – Ty Cobb hits a bunt to break up the no hitter being thrown by A's pitcher Rube Waddell. The A's go on to defeat the Tigers 5–0.
 * July 4 – Mordecai Brown of the Chicago Cubs defeats Lefty Leifield of the Pittsburgh Pirates 1–0, in the first game of a doubleheader, in which both pitchers throw a 1-hitter. Leifield collects the Pirates only hit off Brown and loses his own bid for a no-hitter by giving up a single in the 9th inning that ends up scoring the only run of the game.
 * July 20 – Mal Eason tosses a no hitter for the Brooklyn Superbas, as they defeat the St. Louis Cardinals, 2–0.
 * August 1 – Brooklyn Superbas pitcher Harry McIntire would not allow a hit to the Pittsburgh Pirates through 10 innings, only to allow a single with two outs in the 11th inning. McIntire would allow three more hits before the Pirates outlasted the Superbas, 1–0, in 13 innings.
 * August 3 – At Sportsman's Park, Long Tom Hughes of the Washington Senators and Fred Glade of the St. Louis Browns entered the 10th inning with a scoreless tie, until Hughes decided the game with a solo home run to a 1–0 victory, becoming the first pitcher in major league history to pitch a shutout and hit a home run which accounted for the only run in the game.
 * September 1 – The Philadelphia Athletics Jack Coombs and the Boston Americans' Joe Harris each pitch all 24 innings of the A's 4–1 victory over the Pilgrims at Boston's Huntingdon Avenue Grounds. Coombs and Harris still hold the American League record. The major league record is held by the Brooklyn Dodgers' Leon Cadore and Boston Braves' Joe Oeschger, who battled to a 26-inning, 1–1 deadlock on May 1, 1920.
 * October 14 – In perhaps the greatest upset in World Series history, the Chicago White Sox (93 wins) defeated the Chicago Cubs (116 wins), 8–3, in Game 6, winning the World Championship, four games to two, despite hitting only .198 and committing 15 errors in the series.
