Major League Baseball (MLB) is a professional baseball organization, the oldest of the four major professional sports leagues in the United States and Canada. A total of 30 teams now play in the American League (AL) and National League (NL), with 15 teams in each league. The AL and NL operated as separate legal entities from 1901 and 1876 respectively. After cooperating but remaining legally separate entities since 1903, the leagues merged into a single organization led by the Commissioner of Baseball in 2000.
