Astros 5, Diamondbacks 4 (10): Chris Carter blasted a lead-off home run in the 10th inning after Arizona's Miguel Montero's solo homer tied the game in the ninth and Houston completed a sweep of the brief two-game set against visiting the Diamondbacks.
Carter, who had two solo homers in Wednesday's contest, gave the Astros their first walk-off victory of the season by depositing a 2-2 offering from J.J. Putz (1-1) deep into the left-field seats.

Arizona forced extra innings when Montero homered on the first pitch from closer Chad Qualls in the ninth, ending Qualls' 19-game scoreless streak.
Singleton put the Astros ahead 2-1 in the third with a one-out solo homer off Wade Miley, who yielded four runs while striking out eight over five frames. Houston extended its lead in the fourth on Corporan's two-run blast after Robbie Grossman drew a leadoff walk.
Didi Gregorius scored on a wild pitch in the sixth to cut the deficit to 4-2 and Arizona moved closer on Chris Owings' solo homer in the seventh.
