National Baseball League (Alternity)

Major League Baseball (MLB) is the primary professional baseball league in the United States. It was founded in 1869 and is one of the oldest professional sports leagues in the Americas. Before 1869, the MLB was comprised of many small teams that competed in other baseball leagues, and it wasn't until the late 1800s that the MLB established mainstay franchises to exclusively play in their league.

The MLB is currently divided between two leagues, the American League (AL) and the National League (NL), with each league consisting of three divisions: the East, Central, and West Divisions. The MLB is currently composed of 30 teams, with 2 more planned to start by 1998. The MLB competes in a 162 game season starting on the first Sunday in April and ending on the first Sunday of October. Each team competes to earn a spot to compete in the playoffs to earn a chance to play in the MLB World Series.
