- April 11 – At the Polo Grounds, Babe Ruth of the Boston Red Sox pitches a three-hitter in shutting down the New York Yankees on Opening Day, 1–0. Ruth's performance marks the start of good things to come. He will win 24 games this year, while leading the American League with 35 complete games.

- May 2 – In one of the most outstanding pitching duel's in baseball history, Cincinnati Reds pitcher Fred Toney tosses a 10-inning no-hitter in a 1–0 win over the Chicago Cubs. Opposing pitcher Hippo Vaughn did not surrender a hit until a one-out single in the 10th inning.
- May 5 – Ernie Koob pitches a no-hitter to lead the St. Louis Browns to a 1–0 victory over the Chicago White Sox.

- May 7 – Babe Ruth pitches a shutout and drives in the game's only run on a sacrifice fly as the Red Sox top Walter Johnson and the Senators, 1-0.
- June 23 – Ernie Shore of the Boston Red Sox pitched the most notable game of his career leading his team to a 4–0 win against the Washington Senators. Babe Ruth started the game for Boston but walked the leadoff hitter, Ray Morgan. Ruth then engaged in a heated argument with home plate umpire, Brick Owens, who tossed Ruth out of the game. Then Shore came into the game to relieve Ruth. Morgan was caught stealing, and Shore retired the next 26 Senators he faced. At the time, Shore was credited with a perfect game, but since then, the criteria have been revised, and Shore's name has been removed from the record books, although he still gets credit for a combined no-hitter.
