Major league baseball final standingsEdit
- January 4 – The Baltimore Orioles club incorporates. John McGraw is manager and part-owner.
- January 27 - Hugh Duffy Jumps from the Boston Beaneaters to the Milwaukee Brewers.
- 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.
- 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.
- March 11 - John McGraw, manager of the Baltimore Orioles of the American League, attempts to sign infielder Charlie Grant, a black man, and attempt to pass him off as a Cherokee Indian named Tokohoma. However, Chicago White Sox president Charles Comiskey recognizes Grant and McGraw's attempt to integrate major league baseball falls apart.

- 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.
