Oswalt Hurts Back Running The Bases

One of the Philadelphia Phillies "Four Aces" has folded.

Roy Oswalt had to leave tonight's game against the Florida Marlins after six innings with a lower back strain. Oswalt was hurt running to first after he laid down a bunt in the bottom of the sixth. He stayed in and ran the bases but left the game after attempting some warm up pitches.

This could affect the Phillies if Oswalt has to miss any significant amount of time. I don't think he'll miss anything beyond his next start, but with sports injuries you never know.
