Sandoval took three different San Diego relievers deep, capping off his big day with an opposite-field three-run blast off of Dale Thayer in the top of the ninth inning. It was the Giants' sixth long ball of the game, setting a new single-game Petco Park record for home runs by a visiting team.
Sandoval finished the game 4 for 5 with six runs batted in. It was the second three-homer game of his career; the first came in Game 1 of the 2012 World Series. Sandoval was voted the most valuable player of that series, and became the first World Series MVP to hit three home runs in a game in the following season, per ESPN Stats and Info.
Sandoval now has seven career multi-home run games.
