The 1997 American League Championship Series (ALCS) pitted the Cleveland Indians, who won coming back against the defending World Series champion New York Yankees in the AL Division Series, and the Baltimore Orioles, who went wire-to-wire and beat the Seattle Mariners in the Division Series. In a role reversal from their 1996 ALDS encounter, the Indians stunned the Orioles, winning on bizarre plays or remarkable comebacks, and won the Series four games to two, but went on to lose to the Florida Marlins in the well-fought, seesaw, seven-game battle of the 1997 World Series. The Orioles had home field advantage, which was predetermined and assigned to either the East Division champions or their opponents in the Division Series.
