MLB

Major League Baseball - the catch-all term for the two top-level leagues of pro baseball in North America. Consists of 14 teams in the American League, and 16 in the National League. The National League has been in existence since 1876, with the American league having been established in 1901.
Since 1903, the champions of both leagues have met at the conclusion of their seasons to determine the MLB champion, in the (often accused of bearing a false name) World Series.

MLB.com is the place to go for baseball higlights, scores, and analysis.
