Peavy, who will be making his third start since returning from surgery last year, allowed three hits and no walks against the Indians. It was his first win since June 25, 2010.
He said on Monday that he feels better than ever after throwing his bullpen session on Saturday. The White Sox are currently using a six-man rotation, so Peavy is probably the biggest beneficiary of an extra day off.
"I threw a nice little side," Peavy said. "The extra day is so big. Today should be my day. I have no problems pitching on this day. That extra day is big in recovering and it's just one more day for you to feel even better than you already do."
It's strange to be pitching in a six-man rotation -- the Red Sox are the only other team to do it this season -- but Peavy said it might help out all of the starters later in the season.
"When you have six guys who are throwing the ball as well as we have, knock on wood, we have six guys who give us a chance every time we go out," Peavy said. "I can't see us staying in this the rest of the season, but I can't see us not having a little bit of an advantage over guys in August and September when we have to be 'whip hard,' so to speak, going out of the back stretch. At that point in time, you're letting it all hang out. I can see us being a little bit ahead of the pack."
