AL East Division
From BR Bullpen
The American League East Division, often abbreviated AL East, was created in 1969 when Major League Baseball expanded and split the American League and National League into two division each. The AL East division has had the following constructs:
1972-1976: Baltimore Orioles, Boston Red Sox, Cleveland Indians, Detroit Tigers, Milwaukee Brewers, and New York Yankees.
1977-1993: Baltimore Orioles, Boston Red Sox, Cleveland Indians, Detroit Tigers, Milwaukee Brewers, New York Yankees, and Toronto Blue Jays.
1994-1997: Baltimore Orioles, Boston Red Sox, Detroit Tigers, New York Yankees, and Toronto Blue Jays.
1998-2007: Baltimore Orioles, Boston Red Sox, New York Yankees, Tampa Bay Devil Rays, and Toronto Blue Jays.
2008-present: Baltimore Orioles, Boston Red Sox, New York Yankees, Tampa Bay Rays, and Toronto Blue Jays.
 Division Champions
- Season shortened by the 1972 strike; as a result, the Detroit Tigers won the Division title by only 1/2 game over the Boston Red Sox.
- The New York Yankees won a one-game playoff with the Boston Red Sox for the Division title.
- Split-season format adopted because of the 1981 strike. The New York Yankees won the first-half title and the Milwaukee Brewers won the second half title. The Yankees defeated the Brewers in the Division Series to represent the AL East in the 1981 ALCS.
- The 1994 postseason was cancelled because of the 1994 strike; first season played under three-division format.
- The New York Yankees and Boston Red Sox finished with identical records, but New York was awarded the Division title due to its better head-to-head record against Boston.
