The 2013 American League Championship Series was a best-of-seven playoff pitting the Boston Red Sox against the Detroit Tigers for the American League pennant and the right to play in the 2013 World Series against the St. Louis Cardinals. The Red Sox won the series 4 games to 2. The series was the 44th in league history, and was the first postseason meeting between the two teams. Fox aired all games in the United States. This is, to date, the final League Championship series to air in its entirety on broadcast television; all of Fox's subsequent LCS series have been primarily broadcast on FS1.
