Major League Baseball

MLBMajor LeagueMajor Leagues
The American League of Professional Baseball Clubs, or simply the American League (AL), is one of two leagues that make up Major League Baseball (MLB) in the United States and Canada. It developed from the Western League, a minor league based in the Great Lakes states, which eventually aspired to major league status. George Herman ("Babe") Ruth (1895–1948), noted as one of the most prolific hitters in Major League Baseball history, spent the majority of his career in the American League with the Boston Red Sox and the New York Yankees (plus his first year with his hometown team, the Baltimore Orioles of the minor level International League).
A total of 30 teams play in the National League (NL) and American League (AL), with 15 teams in each league.

Western League (1885–1899)

Western LeagueAmerican Leagueearliest progenitor
It developed from the Western League, a minor league based in the Great Lakes states, which eventually aspired to major league status.
In 1900, the league was renamed the American League, and declared its major league status in 1901 against the older National League of 1876, which was centered in the American Northeast states.

World Series

championship seriesFall ClassicWorld Championship
At the end of every season, the American League champion plays in the World Series against the National League champion; two seasons did not end in playing a World Series (1904, when the National League champion New York Giants refused to play their AL counterpart, and 1994, when a players' strike prevented the Series).
The World Series is the annual championship series of Major League Baseball (MLB) in North America, contested since 1903 between the American League (AL) champion team and the National League (NL) champion team.

National League

NLNationalNational League of Professional Baseball Clubs
It is sometimes called the Junior Circuit because it claimed Major League status for the 1901 season, 25 years after the formation of the National League (the "Senior Circuit"). Originally a minor league known as the Western League which existed 1885 to 1899, with teams in mostly Great Lakes states, the newly organized Western League later developed into a rival major league after the previous American Association (1882–1891) disbanded after ten seasons as a competitor to the older National League of Professional Baseball Clubs (usually known as the National League) which was founded in 1876. The American League has one notable difference versus the rival National League, in that in modern times since 1973 it has had the designated hitter rule.
Founded on February 2, 1876, to replace the National Association of Professional Base Ball Players (NAPBBP) of 1871–1875 (often called simply the "National Association"), the NL is sometimes called the Senior Circuit, in contrast to MLB's other league, the American League, which was founded 25 years later and is called the "Junior Circuit".

Under the rule, a team may use a batter in its lineup who is not in the field defensively, replacing the pitcher in the batting order, compared to the old rule that made it mandatory for the pitcher to bat.
Starting in 1973 with the American League and spreading to further leagues throughout the 1980s and 1990s, the hitting duties of the pitcher have generally been given over to the position of designated hitter, a cause of some controversy.
