Semien went 2-for-5 with a grand slam and a second run scored in Friday's 9-8 win over the Astros.
His seventh-inning blast, Semien's sixth home run of the year, tied the game at 7-7 to set up some ninth-inning heroics by Jed Lowrie. It was Semien's first home run since Aug. 16, but he's still been productive despite the power outage, slashing .295/.348/.443 with 11 runs and 11 RBI over his last 14 games.
