CHICAGO -- Jake Peavy will begin a rehab assignment with Triple-A Charlotte on Thursday after throwing off the mound Saturday, and the Chicago White Sox's recently acquired right-hander could be back in the big leagues this month.
Peavy is scheduled to start Thursday for Charlotte and is expected to throw two to three innings. On the disabled list since June 13 with a strained right ankle tendon, Peavy was acquired from the San Diego Padres on July 31.
"It went well. I think we threw 50, a little bit over 50 pitches maybe. But things went well. It was the first time on the mound with batters in," Peavy said. "I've still got a long way to go, but [it was] a good first step. The biggest thing is pain free and just trying to get my arm strength back, get my legs out under me."
He is hoping to make three rehab starts before being activated from the disabled list, but White Sox general manager Ken Williams won't be surprised if Peavy only needs two starts before his return to the majors.
"I've expressed to him a desire that I would like to see him get three rehab starts," Williams said. "I suspect after watching him today, I suspect at some point he is going to come to me that he doesn't need it, based on what I saw today. But I am more concern with him being healthy, being strong, going out there being the guy he can be."
Peavy is tentatively scheduled to pitch in the minors on Aug. 18 and 23.
Williams also noted veteran right-hander Bartolo Colon is no longer part of the White Sox plans. Colon is on the disabled list with right elbow inflammation. Colon is 3-6 with a 4.19 ERA.
Williams did not comment on speculation that the White Sox claimed Toronto outfielder Alex Rios on waivers.
"I am not confirming or denying any interest or any claims or anything," Williams said. "But if these things get out on a daily basis, boy, it's going to be a heck of an August around here around in terms of how many players you claim and how many you don't claim."
