Buster Posey struggled in his first few at-bats Saturday night, so he switched to a different bat for his final plate appearance. The move worked for the Giants' catcher as he had the game-winning hit that gave San Francisco a little more breathing room in the NL West. Joe Panik hit a game-tying single off Los Angeles closer Kenley Jansen with one out in the 10th inning and scored on Posey's RBI single, and the Giants beat the Dodgers 5-4 on Saturday night.
