Jake Peavy exits with strained groin

CHICAGO -- White Sox right-hander Jake Peavy now has a new injury issue to deal with after he lasted just four innings and 75 pitches of Sunday's start against the Detroit Tigers.

Peavy was removed because of a strained right groin. He will be re-evaluated Monday and there is no estimate on when he might be able to pitch again, although he is expected to miss at least one start and probably more.

"I can feel it when I walk so I can't imagine in four days or five days from now it being completely gone where I can go out and drive off a mound and pitch in a game," a dejected Peavy said after Sunday's outing. "That's just me but certainly nothing's etched in stone."

Peavy said the injury first started to bother him during his previous start in Boston on Monday. It started to flare up on him in the second inning Sunday, enough to get it wrapped and to take some pain medication.

Peavy struck out the side in the first inning and was perfect over the first three innings. He struggled mightily in the fourth, though, and wasn't helped by the defense's failure to turn a double play early in the inning when Alexei Ramirez's relay throw to first base went wide. That was the play that Peavy said did him in as he tried to sprint to cover first base.

"After that, it was hard for me to stay mechanically anywhere close to what I was previously," he said. "I didn't make a whole lot of pitches after that. I came in here and talked it through with those guys and I don't think it was smart to even go back out there and try."

A previously struggling Ryan Raburn delivered the big blow in the fourth with a grand slam that gave the Tigers a 6-2 lead. Detroit went on to win 7-3. Peavy threw 38 pitches in the first three innings and 37 in the fourth when he gave up three hits, three walks and six earned runs.

Peavy was replaced at the start of the fifth inning by Will Ohman. It was the least amount of pitches he has thrown in a start this season, not counting his three-inning rain-shortened outing against the Texas Rangers on May 24.

Peavy was making just his fifth start since surgery last July to reattach his latissimus dorsi muscle.

"I don't know what to say. I'm frustrated as you can imagine," Peavy said. "I felt so good to start the game and then to have something nagging to turn into what it turned into, to cause me to come out of the game and let alone to not be able to make pitches to even give my team a chance to win today when I really felt I had it today. Today could have been a special day and I could have gone out and helped this team win."

The groin is just the latest in a series of injuries Peavy has dealt with since coming to the White Sox in a 2009 trade with the San Diego Padres. When he was traded he was dealing with a strained right ankle. That injury is believed to have led to altered mechanics that was at least partly to blame for his lat detachment.

During spring training, as he rehabbed from the lat surgery, Peavy had two setbacks. One was for rotator cuff tendinitis while the other was because of discomfort while breaking through scar tissue from the surgery.

The White Sox have been in a six-man rotation since Peavy returned from the disabled list on May 11 and will return to a five-man staff for the time being.

"We want Peavy on the mound every five, six days, but as a manager you can't control that," Ozzie Guillen said. "He was doing everything fine between starts and everything was good until today's game."
