In Major League Baseball, the American League Championship Series (ALCS), played in October, is a round in the postseason that determines the winner of the American League pennant. The winner of the series advances to play the winner of the National League Championship Series in baseball's championship, the World Series.
It started in 1969, when the American League was reorganized into two divisions, East and West. The winners of each division played each other in a best-of-five series to determine who would advance to the World Series. In 1985, the format changed to best-of-seven. In 1994, the league was restructured into three divisions, with the three division winners and a wild-card team advancing to a best-of-five postseason round, known as the American League Division Series (ALDS). The winners of that round then advanced to the best-of-seven ALCS. in 2012, the playoffs were expanded again so that two wild card teams face off in a one game wild card round to determine which team advances to the division series, with the playoffs then continuing as it had before 2012 (though with the possibility of a fifth seed being in the playoffs and a fourth seed being out) after the end of the wild card round. This is the system currently in use.
