In the NL Division Series (NLDS) against the Braves, Posey batted .375 as the Giants won the series in four games. In Game 4 of the NL Championship Series (NLCS) against the Philadelphia Phillies, he became the first rookie to get four hits in an NLCS game as the Giants won 6–5. He batted .217 with five hits and three RBI in the series as the Giants defeated the Phillies in six games. In Game 4 of the World Series against the Texas Rangers, Posey and Madison Bumgarner formed the first rookie starting pitcher-catcher tandem in a World Series since Yogi Berra caught Spec Shea in Game 1 of the 1947 World Series. Posey hit his first postseason home run against Darren O'Day in the 4–0 victory, making him the fifth rookie catcher to hit a home run in the World Series. The Giants won the series four games to one, giving Posey (who batted .300 with a home run and two RBI in the Series) his first World Series ring. Posey caught every inning of the playoffs for the Giants.
