National League (Major League Baseball)

History and development

The league originated in the late 19th century as professional baseball organized into a single, stable circuit. The annual championship series pitting the National League winner against the American League winner dates to the early 20th century and is known as the World Series. Over many decades the NL has seen changes in rules, team locations and playoff formats while remaining a central institution in North American professional sports.

Structure and competition

Teams in the National League are grouped into divisions (East, Central and West) for scheduling and postseason qualification. As of 2016 the NL comprised 15 teams; a current list of teams shows historic franchises and newer additions. During the regular season clubs play a schedule that determines division winners and additional qualifiers for the playoffs. In the 2010s several formats sent five teams from the NL into the post-season, though the precise number and arrangement of wild-card berths has varied with later rule changes.

Characteristics and notable traditions

• Because of its long history the NL includes some of baseball's most storied franchises, rivalries and ballparks.
• Traditionally the National League did not use the designated hitter, so pitchers batted; recent rule changes have affected that practice in some seasons.
• The NL champion earns the right to represent the league in the World Series, with the series winner recognized as Major League Baseball champion.

Importance and legacy

The National League has shaped the development of professional baseball in North America through its teams, innovations and rivalries. Its place alongside the American League creates the cross-league championship and a structure that has supported both local fan cultures and nationwide baseball traditions.
