Being from Houston and watching pretty much Oswalt pitch every game since he started, I think he can pitch a no-no through about 6 or 7 but not the full game. In his current later years, Oswalt has a tendency to get tired around the 6 inning and teams started banging him around. In his first 4 years, I would say yes but not currently. This year, I would probably say Dontrelle Willis.
