Jake Peavy gets extra rest

DETROIT -- The All-Star break isn't the only extra rest Jake Peavy will get as the second half begins in earnest for the Chicago White Sox.

Originally expected to pitch Sunday against the Detroit Tigers, Peavy's first start of the second half has been moved to Tuesday at Kansas City. Phil Humber will be moved into the series at Detroit and start Sunday.

Peavy hasn't been sharp of late, closing out the first half for the White Sox with a disappointing outing against the Minnesota Twins. His last effective outing was a relief appearance June 25 against the Washington Nationals.

"I may have been riding a little high after the relief effort and wanted to pitch a couple more times (before the All-Star break)," said Peavy, who had his latissimus dorsi muscle reattached last July. "I thought my body and arm would respond better than it did. The last few starts was a grind physically. I don't think that was any secret if you watched. I'm looking forward to getting pushed back and getting back on my feet."

During the All-Star break, Peavy worked with a physical therapist near his Alabama home.

"They said stuff we already know," Peavy said. "I just wanted to make sure the arm was as good as it can be. It wasn't anything crazy. You're asking your arm to do something that people would have a hard time doing if they were healthy and have a young, good arm. The arm's on the mend and you have to treat it like that."

Since returning from the disabled list, Peavy is an underwhelming 4-3 with a 5.27 ERA.

The White Sox will go with Gavin Floyd, Edwin Jackson and Humber in that order during the weekend series against the Tigers. They will then use Mark Buehrle, Peavy and John Danks at Kansas City.

Danks will be making his first start since coming off the disabled list. His return marks the return of the six-man rotation the White Sox have used since Peavy made his season debut.

"Just to get back to the routine and throwing, the six-man rotation is probably going to be better for me than the other guys, just because of where I'm at coming off of major surgery," Peavy said.
