- February 27 - The National League Rules Committee decrees that all fouls are strikes, except those hit after two strikes. In order to prevent balls from fouled and lost, the committee urges that "batsmen who foul off good strikes are to be disciplined." Also, now a ball will be called if the pitcher does not throw to the ready batter within 20 seconds, or if the pitcher hits the batter with a pitch.
- March 2 - Jimmy Collins, Hugh Duffy, and Billy Sullivan jump the NL for the new AL. Collins will manage the Boston Americans, Duffy will manage the Milwaukee Brewers, and Sullivan will catch for the Chicago White Stockings.

- April 25 - History is made in just the second day of play in the new American League. The Milwaukee Brewers are leading the Detroit Tigers 13-4 going into the ninth innning, when the Tigers rally and score 10 runs to win, 14-13. This game is the greatest Opening Day rally in Tigers history.
- April 26 - Christy Mathewson makes his major league debut in the New York Giants' opener, beating the Brooklyn Superbas 5-3.
- May 2 - This was the date of the American League's first forfeit, with the Detroit Tigers playing the Chicago White Stockings. The Tigers scored five runs in the top of the ninth to put them on top, 7-5, and the White Stockings began stalling for a rainout. However, the umpire forfeited the game to the Tigers.

- May 21 - Andrew Freedman, owner of the New York Giants, refuses to allow umpire Billy Nash inside the Polo Grounds, accusing him of incompetence. Players from both teams umpired the rest of the game.
