HOUSTON - Astros left-hander Andy Pettitte has a strained muscle in his left forearm and will be evaluated by team doctors in the next few days, but he isn't expected to miss any time.
Pettitte left four innings into Wednesday night's game against the Cubs with discomfort in the forearm. He was clearly distressed by the end of the fourth, wincing in pain as he walked off to end the inning.
He allowed one run and two hits in four innings with four strikeouts.
Team officials said Pettitte is considered day to day but likely will be able to make his scheduled June 4 start against Pittsburgh.
"Maybe it's just a muscle strain, but after I threw a pitch it was grabbing me a little bit," Pettitte said after Wednesday night's game. "It's aggravating, and it's disappointing to have a 4-0 lead and go out there (after) four innings. I just want to go out there and contribute."
Pettitte injured his left elbow while trying to check a swing in his debut with the Astros on April 6 against San Francisco. He missed the next three weeks with a strained elbow.

Peavey, 4-2 with a 2.01 ERA in nine starts, was scheduled to start Saturday in Milwaukee. Right-hander Dennis Tankersley will pitch in his place. "This is more of a precaution than anything else," manager Bruce Bochy said. "We sent Jake home for an MRI and he wasn't going to pitch for a while anyway."

"He ran at about 75 percent and the word was that it was encouraging," manager Terry Francona said, "but he's not (ready) yet." Nixon is scheduled to be evaluated today and play Saturday.
