Baldelli made an impact in his limited post-season playing time. In Game 3 of the 2008 American League Championship Series, Baldelli hit a three-run home run off Boston's Paul Byrd in the eighth inning to help the Rays take a 2-1 series lead. In the decisive Game 7 of the ALCS, his RBI single in the fifth inning gave the Rays their first lead of the game en route to winning their first American League pennant. And in Game 2 of the World Series against the Philadelphia Phillies, Baldelli made a double play by catching a fly ball and throwing back to first baseman Carlos Peña in time to beat Jayson Werth.
