PHOENIX, Ariz. (WTVA/AP) - Colorado Rockies starter Roy Oswalt left Sunday's game against Arizona with a strained left hamstring with two outs in the second inning.
The veteran right-hander ran to cover home plate after a wild pitch as the Diamondbacks' Eric Chavez came home from third. The throw from catcher Wilin Rosario sailed past Oswalt, who immediately indicated he was hurt.
Oswalt had difficulty walking as he was accompanied into the Colorado dugout. Right-hander Edgmer Escalona came on in relief.
Colorado Rockies beat writer Troy Renck tweeted that Oswalt said that he's never pulled his hamstring before and that he "heard it pop". While no formal announcement has come from the team as of yet, Renck added that "[Oswalt]'s out for awhile."
The team called the injury a left hamstring strain. MLB.com reports that it "seems likely" that the injury will force the 35-year-old veteran to be placed on the 15-day Disabled List.
The Weir native still took the loss in Sunday's game, a 6-1 Arizona win, falling to (0-4) this season.
