Marquez cleared waivers and was outrighted to Triple-A Charlotte as the White Sox finalized their 25-man Opening Day roster.
As expected, Peavy was placed on the 15-day disabled list, retroactive to March 22. He will remain in Arizona until he's ready to rejoin the Sox.
He is scheduled to start Sunday in an extended Spring Training game, followed by what he hopes will be an April 8 rehab start at Triple-A Charlotte against Norfolk. Peavy would possibly join the White Sox in Chicago on April 9, missing the season opener and home opener, the first time that has happened in his big league career.
"I'll try to get to where I can throw 100 pitches," Peavy said. "When I can do that and bounce back and do it again five days later, I'm going to say I'm ready to pitch in the big leagues and give it all I can to get back to Chicago. When I get to Chicago, I want to stay there."
One of the more compelling stories in camp over the past six weeks was Peavy's comeback from experimental surgery last July 14 to reattach the tendon that anchors the latissimus dorsi muscle to the rear of his right shoulder. Peavy not only was climbing pitch count-wise with each of his four Cactus League starts, but looked effective in getting the work done.
Manager Ozzie Guillen will start the season with 11 pitchers, two catchers, eight infielders and four outfielders.
The Sox also put outfielder Dayan Viciedo on the 15-day DL, retroactive to March 22, with a fractured right thumb; reassigned catcher Donny Lucy to Minor League camp and purchased the contract of outfielder Lastings Milledge from Charlotte.
