Pittsburgh at Houston

In his last ten starts vs. the Pirates, Roy Oswalt has gone 7-1 with a 1.46 ERA. He had a rough May but is off a win in his last start, allowing just one run. Paul Maholm has been average overall for Pittsburgh and has put up a 5.82 ERA on the road this season. Houston doesn't score a lot but that shouldn't be a problem here as Maholm is just 4-16 the past two seasons when facing a team that scores under 4.4 runs per game! The Pirates lost last game 9-1 and this team is just 6-30 the past three seasons on the road after a game in which they allowed 9+ runs. Meanwhile Houston is 11-2 over the past two seasons after scoring 9+ runs. Oswalt and the Astros get the call here.
