National League final standings
- January 4 – The Baltimore Orioles club incorporates. John McGraw is manager and part-owner.
- January 28 – The American League formally organizes. The eight original clubs were the Chicago White Stockings, Milwaukee Brewers, Indianapolis Hoosiers, Detroit Tigers, Kansas City Blues (reconstituted as the Washington Senators (1901–1960)), Cleveland Lake Shores, Buffalo Bisons, and Minneapolis Millers. The Hoosiers, Bisons, and Millers are contracted; the Boston Americans, Baltimore Orioles, and Philadelphia Athletics are admitted. Teams are limited to 14 players and will play 140 games per season.
- February 8 – Philadelphia Phillies second baseman Nap Lajoie, along with pitchers Chick Fraser and Bill Bernhard, jump to the new American League Philadelphia club, the Athletics.
- February 27 – The National League Rules Committee decrees that all foul balls are to count as strike balls, except after two strikes. To cut the cost of lost foul balls, the committee urges that batters who foul off good strikes are to be disciplined. The American League will not adopt this rule for several years. Other new rules: catchers must play within 10 feet of the batter; a ball will be called if the pitcher does not throw to a ready and waiting batter within 20 seconds, and players using indecent or improper language will be banished by the umpire. A ball will be called when a batter is hit by a pitch, but, in a mail vote, the owners will rescind this in April, and a HBP will earn a batter first base.
- 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 17 – The Philadelphia Athletics are beating the Washington Senators 7-6 in the bottom of the ninth when Senators player Bill Coughlin hits an apparent game-ending home run. However, under the rules of the time, Coughlin is credited with just a single, as that is all that it would have taken for the Senators to beat the Athletics.
- May 21 – Andrew Freedman, owner of the New York Giants, refuses to allow umpire Billy Nash inside the Polo Grounds, accusing him of incompetence.
- May 23 – Nap Lajoie, on his way to hitting a record .426 for the Philadelphia Athletics, is considered such a dangerous hitter by the Chicago White Stockings that he is intentionally walked with the bases loaded.
- May 27 – Third baseman Jimmy Burke of the Milwaukee Brewers sets an American League record by committing four errors in an inning. This record will be tied in 1914 by the Cleveland Naps' Ray Chapman, and in 1942 by the Chicago Cubs' Lenny Merullo.
