American League

American League. One of the two leagues that constitute Major League Baseball (MLB), the American League (AL) was established in 1901 as a major professional baseball circuit. Under the leadership of its founder, Ban Johnson, it challenged the established National League and achieved major league status. The league is distinguished by its use of the designated hitter rule, which was adopted in 1973. Its champion, determined through the American League Championship Series, meets the National League champion in the World Series.

History

The league was founded on January 28, 1901, in Chicago as a rival to the older National League, with its first president, Ban Johnson, aggressively recruiting talent from existing leagues. Early franchises included the Baltimore Orioles, Boston Americans, Chicago White Sox, Cleveland Blues, Detroit Tigers, Milwaukee Brewers, Philadelphia Athletics, and Washington Senators. A pivotal peace agreement, the National Agreement of 1903, ended hostilities with the National League and established the framework for the modern World Series. The league survived challenges like the Federal League and expanded westward, adding teams like the Los Angeles Angels in 1961. Key moments include the 1969 expansion that created two divisions and the 1994 realignment into three divisions, culminating in the introduction of the Division Series.

Organization

The league operates under the umbrella of Major League Baseball, with its rules and governance unified under the office of the Commissioner of Baseball, currently Rob Manfred. A key distinguishing rule is the use of the designated hitter (DH) in all games, a practice adopted in 1973. For most of its history, the league used a single league president, such as Will Harridge and Lee MacPhail, but that office was largely absorbed by the Commissioner's office in 1999. The 15 teams are divided into three divisions: the American League East, American League Central, and American League West. This structure determines qualification for the Major League Baseball postseason, with division winners and wild card teams advancing.

Champions and postseason

The league champion is crowned by winning the American League Championship Series (ALCS), a best-of-seven series that began in 1969. The ALCS winner advances to face the National League champion in the World Series. The most successful franchise is the New York Yankees, with 40 AL pennants and 27 World Series titles. Other multiple champions include the Oakland Athletics (9 pennants), Boston Red Sox (14 pennants), and Detroit Tigers (11 pennants). The postseason format has evolved, now featuring the American League Division Series (ALDS) and the Wild Card Series. Recent champions include the Houston Astros (2022) and the Texas Rangers (2023). Individual postseason excellence is recognized with awards like the ALCS Most Valuable Player Award.

Rivalries

Intense rivalries are a hallmark, often defined by geographic proximity, postseason meetings, and historical significance. The most famous is the rivalry between the New York Yankees and Boston Red Sox, intensified by the Curse of the Bambino and dramatic playoff series like the 2004 American League Championship Series. Other historic rivalries include the Chicago White Sox versus the Cleveland Guardians (formerly Indians) in the AL Central, and the Oakland Athletics versus the Los Angeles Angels on the West Coast. Interleague play, introduced in 1997, has fostered new rivalries, such as the Subway Series between the Yankees and the New York Mets and the Freeway Series between the Angels and the Los Angeles Dodgers.

Teams

The league currently consists of 15 member clubs. The American League East comprises the Baltimore Orioles, Boston Red Sox, New York Yankees, Tampa Bay Rays, and Toronto Blue Jays. The American League Central includes the Chicago White Sox, Cleveland Guardians, Detroit Tigers, Kansas City Royals, and Minnesota Twins. The American League West is made up of the Houston Astros, Los Angeles Angels, Oakland Athletics, Seattle Mariners, and Texas Rangers. Franchise histories vary, with the Yankees (originally Baltimore Orioles) and Tigers maintaining continuous operation in their current cities since 1901, while others like the original Washington Senators relocated to become the Minnesota Twins.
