Oswalt heading to Houston to have hamstring checked
Astros general manager Ed Wade said Friday ace right-hander Roy Oswalt will head to Houston to have his left hamstring examined by team medical director Dr. David Lintner. Oswalt left Friday’s game against Pittsburgh after four innings with a hamstring strain.
“Sunday’s rainout after he left the mound after the rain delay he went in the cage and felt a tug in his glut, and since it’s the same leg and had two things now occur, we’re going to get him to Houston and let Dr. Lintner look at him,” Wade said.

Maybe we should rename the team to the Houston DLs.
