The 2004 American League Championship Series was the Major League Baseball playoff series to decide the American League champion for the 2004 season. It was played between the Boston Red Sox and New York Yankees, at Fenway Park and the original Yankee Stadium, from October 12 to 20, 2004. The Red Sox became the first, and still only, team in MLB history to come back from a 0-3 deficit to win a seven-game series. The Red Sox, who had won the AL wild card, defeated the Anaheim Angels in the American League Division Series to reach the ALCS, while the Yankees, who had won the AL East with the best record in the AL, defeated the Minnesota Twins.
