Until the 2014 season, every season's postseason had featured one or both of the AL East rivals since the inception of the wild card format and the resultant additional Division Series; they have faced each other in the AL Championship Series (ALCS) three times. The Yankees won twice, in 1999 and 2003; while the Red Sox won in 2004. The two teams have also met once in the AL Division Series (ALDS), in 2018, with Boston winning 3-1, a series which included a 16-1 Red Sox win in Game 3 at Yankee Stadium, the most lopsided postseason loss for the Yankees in their history. In addition, the teams have twice met in the last regular-season series of a season to decide the league title, in 1904 (when the Red Sox, then known as the Americans, won) and 1949 (when the Yankees won).
