Carlos Pena drilled a walk-off three-run home run to right field in the 10th inning Thursday afternoon, giving the Astros a 7-4 victory over the Brewers on an afternoon that featured more errors than clutch hits.

Both teams gave up three unearned runs, but Carlos Corporan’s leadoff home run in the eighth tied the score at 4 Thursday afternoon.

Two innings later, Pena rewarded the crowd of 17,083 at Minute Maid Park to help the Astros win three-game interleague series against their former NL Central rivals, 2-1.
