CLEVELAND -- Jake Peavy took another step toward a Major League comeback from 2010 season-ending experimental surgery to reattach the tendon that anchors the latissimus dorsi muscle to the rear of the shoulder by throwing 59 pitches over four innings in a simulated Minor League intrasquad game at Camelback Ranch in Glendale, Ariz., on Sunday.
Next up for Peavy is a Friday start for Double-A Birmingham at Montgomery, Ala., where he hopes to work five innings and throw 75 pitches.
"I look forward to the rehab starts and having more adrenaline," Peavy told a pool reporter by phone.
Peavy threw in a similar simulated game last Tuesday, and at the time, targeted back-to-back efforts of at least 100 pitches before he could take the fifth spot in the White Sox rotation. That target also included a strong bounce-back between starts, putting this recent bout of rotator cuff tendinitis behind him.
As of Sunday, Peavy reported nothing but positive feelings in regard to his shoulder and the surgically repaired area.
"The throwing sessions and the treatments with anti-inflammatories have a lot to do with this," Peavy said.
Peavy worked the first inning out of a full windup and the next three from the stretch. He worked primarily on fastball command.
"Pitching out of the stretch is where you make your biggest pitches," Peavy said. "You want to feel comfortable in the stretch.
"There are a lot of young [Minor League] guys swinging, and I could get a lot of swings and misses. But pitching is about fastball command, and that's where it starts. Certainly, I could tell I started fatiguing in the fourth. But I did feel better than I did on Tuesday."
