Major Leagues

The Major Leagues, also known as Major League Baseball or "MLB," are the two major professional baseball leagues in North America; the National League, founded in 1876, and the American League, founded in 1901. Once bitter competitors, the two are now amalgamated into the same general organizational structure. The champions of the two leagues face eath other in the World Series every October, a best-of-seven games series that determines the overall MLB champion.
