Gallo went 1-for-3 with a three-run home run Thursday's loss to the Cubs.
Gallo jumped on a hanging sinker from Drew Smyly in the top of the sixth and launched it into the stands for a three-run shot to give Washington a 6-5 lead. It marked the veteran slugger's third home run this month and the second in his last four games. However, he's still batting a putrid .086 (3-for-35) in September with seven RBI and three runs scored.
