Stewart went 1-for-4 with a three-run home run in Wednesday's 5-3 win over Seattle.
Stewart's three-run shot in the seventh inning was the winning knock for the Reds. It was his second three-run homer in the last four games and the 21st homer overall for the rookie. He's just 3-for-23 (.130) over six games since the All-Star break, but he's contributed nine RBI during that stretch.
