Baseball writers have long posited that the American League East is the toughest division in MLB; during its 50-year existence, an AL East team has gone on to play in the
World Series 28 times, and 16 of those teams have been crowned World Series champions. Since the , when the
wild-card playoff berth was introduced, the AL East has produced 20 of the 32 wild-card teams for the American League, with the AL West sending seven teams, and only five coming from the AL Central. When MLB split into divisions for the , the American League, unlike the
National League, split its 12 teams strictly on geography. The six teams then located in the
Eastern Time Zone were all placed in the AL East, with the other six teams making up the AL West.
Realignment of 1972 In September 1971, American League owners approved the move of the second
Washington Senators franchise to
Arlington, Texas, to become the
Texas Rangers. With the Rangers moving to the AL West, the owners then debated whether the
Chicago White Sox or
Milwaukee Brewers should move to the AL East for 1972. The White Sox requested they be moved to the East under the argument of being an original AL franchise and playing most of their longtime rival teams, of which five were in the East. The
Oakland Athletics (formerly from
Kansas City and
Philadelphia) objected to moving the
White Sox to the East; owner
Charlie Finley was a
Chicago native who wanted to continue to make three trips per season with his club to the Second City. The
Minnesota Twins went a step further and objected to switching either the White Sox or Brewers out of fear of losing their closest geographic rivals and the Twins, citing the National League's lack of geographic accuracy (which placed the
Atlanta Braves in the NL West) in forming its divisions as a reason why the Rangers should not have been shifted out of the East. The Twins also argued that the
National Football League's
Dallas Cowboys played (and still do play) in the
NFC East despite being far from the
Northeast. The White Sox' pleas notwithstanding, the Brewers, who began as the
Seattle Pilots in and had to endure long divisional road trips to Oakland and
Anaheim (and vice-versa) in the AL West, were moved to the AL East. ==Division membership==
