Jake Peavy hopes he doesn’t have to start from the beginning from a physical standpoint by the time he returns from a fractured left rib.

Therefore any activities he can perform while he’s on the 15-day disabled list are seen as positive -- even if it is only 30 minutes spent on an exercise bike and participating in the team’s shoulder program.

Despite some of the pain he felt, Peavy was encouraged by his first activity since he was placed on the DL retroactive to June 5, he said Thursday.

“It wasn’t exactly pain free, but a step in the right direction,” Peavy said. “It was fun to be active again after not being able to do anything for two weeks. The thing for me is to stay active enough to not lose everything you have and have to start from the bottom. I haven’t done any cardiovascular exercises, throwing, shoulder work. That can set you back quite a while if you don’t get back on the horse. To do some stuff with my legs, keep them strong, my shoulder too, I am able to throw a ball here soon. Hopefully won’t lose too much.”

Peavy is expected to miss at least two-to-four more weeks with the injury. When he was placed on the DL, the White Sox said they believe Peavy will be back on the mound after six weeks. The team has a second MRI planned for either the end of this 10-game road trip or shortly after the team returns home to ensure Peavy is healing properly.

Because of the location of the injury, Peavy was told to rest and those orders have been strictly enforced.

“At this point, anything is encouraging,” manager Robin Ventura said. “It’s unique, just something you can’t really exert yourself. He’s happy to actually be doing something, which is good.”

Peavy is 6-4 with a 4.30 ERA in 11 starts this season. He has struck out 66 batters in 67 innings only one season after he led the White Sox with 219 innings pitched. Peavy trusts that he remains on schedule and should be back in a month but isn’t sure what the next step is in his rehab process or when he might next take the mound.
