The American League Championship Series serves as the second MLB playoff round and determines the winner of the AL pennant. The AL champs following the series move on to face the National League Champions in the World Series. Both the ALCS and NLCS showcase a best-of-seven series in a 2-3-2 format since expanding the rounds in 1985. Games 1, 2, 6, and 7 if necessary are annually played at the higher seeds ball field with all other games hosted by the contenders.
2009 featured the New York Yankees and Los Angeles Angels. Both clubs swept their respective opponents (Red Sox, Twins) in the ALDS on their way to fight for AL Championship rights. The Yankees eventually took the pennant after defeating LA in Game 6 at Yankee Stadium. New York is back to compete in 2010 against the AL West champion Texas Rangers, who will be making their first ALCS appearance in club history.
