Roy Oswalt's back gets an evaluation today after it forced him to miss a start yesterday:

Oswalt is unsure whether the hamstring injury had anything to do with the back problems that sidelined him Sunday.

"(The strained hamstring) may have changed my mechanics in St. Louis, but it seems like I would have felt it the next day or two," Oswalt said. "I really didn't feel it until the fourth day."

After Sunday's game, Oswalt was unsure whether he would be placed on the disabled list. Garner said the team's doctors will determine that in the next couple of days.

Nieve was scheduled to start tonight's game against the Chicago Cubs, but Garner said rookie Taylor Buchholz will start instead and Wandy Rodriguez will get the nod Tuesday.

It's almost always the case that pitching through an injury is the wrong thing to do (unless you're Curt Schilling).
