The American League East is one of Major League Baseball's six divisions (An East, Central, and West Division for each of the two leagues). This division was created before the start of the 1969 season along with the American League West Division. Before that time the American League had existed as a single league of 10 teams.
During its 46-year existence, an East Division team has gone on to play in the World Series 25 times, and 14 of those teams have been crowned World Series Champions. Since the 1995 season when the wild-card playoff berth was introduced, the AL East has produced the wild-card team for the American League in 13 out of the 17 years (the West Division three, and the Central Division just one).
B Washington franchise moved to Dallas/Ft. Worth, became Texas Rangers and moved into AL West. Either Milwaukee or the Chicago White Sox would have had to move to the East, eventually it was decided that Milwaukee make the switch.
‡ - In 1978, the New York Yankees ended up in a tie with the Boston Red Sox for the division championship, and won a 1-game playoff against Boston.
* - Due to the players' strike, the season was split. New York won the first half and defeated second-half champion Milwaukee (62–45) in the postseason.
§ - Due to the 1994 baseball strike starting August 12, no official winner was awarded. New York was leading at the strike.
†† - The Boston Red Sox and New York Yankees finished the 2005 season tied for first place with identical records. New York won the season series against Boston and was awarded the tie-breaker; Boston was awarded the wild card berth. Had a team from another division won the wild card, a one-game playoff would have decided the division champion.
* – Starting with the 2012 season, there will be two Wild Card winners in each league. The qualifiers will play a single-game playoff to determine who will face the top-seeded team in the American League Division Series.
** In 2013, the Texas Rangers and the Tampa Bay Rays finished the season with the identical records of 91–71. A one-game playoff was held and the Rays won it 5–2 over the Rangers to capture the second Wild Card berth.
