Pittsburgh, PA Ė Paul Maholm twirled a three-hit shutout to pitch Pittsburgh past Houston, 9-0, and finish off a three-game set at PNC Park.
Maholm (6-7) did not walk a batter, struck out one and did not allow a runner to advance past first base in his second career shutout for the Pirates, who took the last two games of the series by outscoring the Astros, 21-6.
Garrett Jones belted a two-run homer, Ronny Cedeno had four hits -- three doubles -- and scored twice and Ryan Doumit added three hits, a run scored and a run batted in for Pittsburgh, which banged out a season-high 19 hits to win a third straight home series.
Roy Oswalt (6-11) took the loss after yielding two runs on seven hits while fanning five over four frames. He left the game with a left ankle contusion after being struck by a Pedro Alvarez batted ball in the second inning.
