During the offseason, the Giants had Sandoval work on losing weight. Sandoval, however, saw a sophomore slump in 2010. He struggled all season to come close to his 2009 totals and saw himself dropped to eighth in the batting order in a game on June 5. One bright spot in the season came on August 12, when Pat Burrell and Sandoval hit back-to-back home runs against Randy Wells of the Cubs in an 8–7 victory. Sandoval's home run snapped a 46-game home run drought. Sandoval finished the season with a .268 batting average, 13 home runs, and 63 RBI. He saw his batting average, as a right-handed hitter, plummet over 150 points from his 2009 batting average; he dropped from .379 to .227. His batting average with runners in scoring position also dropped during this period, from .301 in 2009 to .208 in 2010. Overweight and unproductive, he was benched during the 2010 National League Championship Series for Juan Uribe and limited to three at-bats in the 2010 World Series. However, Sandoval earned his first World Series ring as the Giants won their first World Series since 1954, securing the championship in five games over the Texas Rangers.
