HOUSTON -- If anyone needed a shot in the arm and a boost of confidence, it was Astros shortstop Jonathan Villar. He came into Friday's game against the Orioles having been held hitless in his previous seven games and needing something -- anything -- to get him going.

How about a game-winning hit?

The Astros rallied for their seventh win in a row on back-to-back RBI doubles by Robbie Grossman and Villar, who snapped an 0-for-26 drought with his go-ahead hit, in a 2-1 victory over the Orioles in the Civil Rights Game before 38,482 fans at Minute Maid Park.

It's the Astros' longest winning streak since reeling off seven in a row July 27-Aug. 3, 2010.
