Nelson Cruz belted a grand slam home run in the bottom of the 11th inning to give the Texas Rangers a 7-3 victory over the Detroit Tigers on Monday and a 2-0 lead in the best-of-seven American League Championship Series.

Cruz, who tied the game at 3-3 with a seventh-inning blast, connected off reliever Ryan Perry with the bases loaded for the first walk-off grand slam ever in postseason play to thrill the home crowd at Rangers Ballpark in Arlington, Texas.

Ryan Raburn had put Detroit 3-2 ahead with a three-run home run in the third inning before Cruz, who also homered in Game One, got the Rangers back on level terms with a solo shot.

Both teams squandered bases-loaded chances in the ninth before the Rangers made the most of a second opportunity to finish off the Tigers.

The series shifts to Detroit for Game Three on Tuesday, with Texas expected to start Colby Lewis against Doug Fister.
