"Before the White Sox's game with the Twins was postponed Tuesday night because of rain after a 50-minute delay, Jake Peavy volunteered his services as a reliever once he has recovered fully8 from a right groin strain.

"We're sitting here talking about me coming back, and I'm telling (pitching coach) Don Cooper and these guys, 'I'll do whatever needs to be done,'" Peavy said. "If I need to go to the bullpen to help out there, we have five starters doing their thing. I certainly think I can be a leader in the rotation as well and be as good as these guys have been.

"But I'll do whatever it takes because there is no weak link right now on the team. We're swinging the bat offensively. We're starting to catch the ball and play fundamentally a lot better than we did early in the year."

After discussing Peavy's offer with Cooper and general manager Ken Williams, manager Ozzie Guillen said after the postponement that Williams thought it was wiser for Peavy to get through his first minor league rehabilitation start Thursday for Triple-A Charlotte before projecting Peavy's role.

"Kenny wasn't sure about that," Guillen said. "We appreciate (Peavy's offer), but I think it's too early to concern our thinking about bullpen stuff. We appreciate that because he wants to help."

Williams and Guillen are mindful of Peavy's injuries. Peavy missed 10 months because of a detached latissimus dorsi muscle near his right shoulder, and the groin strain occurred in his fifth start since returning from the injury."
