Major League Baseball (MLB) is a professional baseball organization and the oldest major professional sports league in the world.[B] MLB is composed of 30 teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. Formed in 1876 and 1901 respectively, the NL and AL cemented their cooperation with the National Agreement in 1903. They remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball. MLB is headquartered in Midtown Manhattan. It is considered one of the major professional sports leagues in the United States and Canada. 

Each team plays 162 games per season, and six teams in each league advance to a four-round postseason tournament that culminates in the World Series, a best-of-seven championship series between the two league champions first played in 1903. The New York Yankees have the most championships: 27. The reigning champions are the Houston Astros, who defeated the Philadelphia Phillies, 4–2, in the 2022 World Series.<|im_end|>
