Pérez played in six games and received 14 at-bats during the 2014 World Series. He was chosen to start Game 7 in left field over newly-converted first baseman Travis Ishikawa, due to his superior defense. In that game, Pérez made an impressive running catch near the foul line in the fifth inning to rob Norichika Aoki of a double. The catch preserved a 3–2 lead, and Giants eventually won the game and the World Series.
