ANAHEIM, Calif. -- White Sox manager Ozzie Guillen made it official Monday, announcing that Jake Peavy will pitch in a major league game for first time in 10 months when he takes the mound Wednesday against the Los Angeles Angels.
Peavy has been recovering from surgery to reattach the latissimus dorsi muscle behind his right shoulder. He spent the entire offseason rehabbing the injury, then went through two setbacks since spring training began.
"He's going Wednesday and hopefully he stays there for good," Guillen said.
The former Cy Young Award winner with the Padres has been underwhelming over 20 starts with the White Sox since coming over in a trade midway through the 2009 season. He was dealing with an ankle injury then that led indirectly to the lat injury when his mechanics became altered.
Peavy is 10-6 with a 4.11 ERA with the White Sox, hardly representative of his career totals that are 102-74 with a 3.36 ERA.
He started spring training on time with the rest of the team, but experienced rotator cuff tendinitis once Cactus League games began. During a minor league rehab start on April 18, he had to leave the game when experiencing discomfort because of scar tissue.
He will pitch nearly 1½ months after the season began, but it still beats the original estimate after surgery that he wouldn't be ready until July of this season.
Just because he is back, though, doesn't mean Peavy is completely in the clear. Guillen said the club will keep a close watch on the right-hander.
"You always worry, I worry about anyone who goes on the field, but Jake, of course," Guillen said. "This guy has been working so hard and put a lot of hours and rehab. I'd love to see him pitch because that's the only reward he's going to get.
"Since last year, he's been checking doctors and rehab and the bullpens and minor league games. He went through everything and I bet you he can't wait to pitch and stay here and help us every five to seven days. I don't think nobody else wants to be out there more than him because I think he's tired of rehabbing and rehab assignments."
The plan is to go with a six-man rotation at least through this week. Phil Humber, who took Peavy's spot in the rotation when the season began, will start the day after Peavy, in Friday's series opener at Oakland.
