"Jake Peavy admitted Friday that adrenaline might have got the best of him and his right arm as the result of pitching four innings of relief against Washington on June 25.

Peavy shrugged off the option to receive an extra day of rest and made three starts, posting an 0-2 record and 7.72 ERA and complaining of a lack of arm strength that pushed back his next start from Sunday to Tuesday night at Kansas City.

"I may have been riding a little high after the relief effort and wanted to pitch a couple more times," Peavy said. "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. My arm is now at that (point of the) year. I did some good things and not so good things. You realize what your body can and can't take at this point. I hope from here on out I'll be a contributing factor for the rest of the season."

Peavy said he was about about 70 percent strength in each of his past three starts."
