Cox went 2-for-4 with a solo home run in Sunday's 5-4 loss to the Red Sox.
Cox connected on a solo homer in the second inning to extend the Giants' lead to 3-0, though the club would ultimately relinquish the advantage. It marked his first RBI since being recalled from Triple-A Sacramento on Aug. 14, with the 25-year-old going 5-for-21 (.238) with two extra-base hits and two runs across seven games since rejoining the big-league club. Overall, Cox is slashing .255/.255/.489 with five extra-base hits (two homers), four RBI, seven runs and four stolen bases in 50 plate appearances this season.
