Dallas Keuchel tossed seven innings and allowed just one run on four hits Saturday to propel the Houston Astros past the Pittsburgh Pirates, 4-1, at Minute Maid Park. The loss extended the Pirates (74-77) losing streak to five games and drops the Bucs to five games back in the NL Wild Card race.
Astros catcher Jason Castro delivered the decisive blow in the seventh inning when he hit a three-run home run. The blast came off Pittsburgh starting pitcher Kevin Correia (11-10), who allowed four runs on seven hits in six innings of work.
The Astros' bullpen cemented the victory as Hector Ambriz and Wilton Lopez combined to toss two scoreless innings. Lopez pitched in the ninth and collected his seventh save of the season.
Gaby Sanchez's leadoff homer in the second inning was the Pirates' lone score.
