Cubs reliever Guzman has successful shoulder surgery

SURPRISE, Ariz. - Cubs reliever Angel Guzman has had arthroscopic surgery to repair a career-threatening injury to his right shoulder.

The procedure performed Tuesday by noted orthopedist Dr. James Andrews was not as extensive as the Cubs anticipated, meaning he has a better chance to pitch again than first expected.

Guzman had several screws inserted to repair a torn ligament, another in a series of injuries for the right-hander since he debuted in 2006.

The Cubs were hoping he'd be their right-handed setup man after he pitched in a career-high 55 games last season and posted a 2.95 ERA.

• In Tuesday's Cactus League game, Chad Tracy hit a 3-run double and Sean Marshall threw 4 strong innings to lead the Cubs to a 12-1 victory over the Texas Rangers.

Marlon Byrd added an RBI single, and Kosuke Fukudome was 3-for-3 with an RBI double, a walk and 2 runs scored for the Cubs.

Marshall, battling for a spot in the rotation, scattered 3 hits and gave up an unearned run with a walk and 5 strikeouts.

"I'm not saying I'm the perfect candidate for it, but I love to start. I want to start," he said.

Manager Lou Piniella said earlier this week he will announce his rotation Friday. Marshall, who has allowed 3 runs (2 earned) on 7 hits over 11 innings this spring, remains in the mix along with fellow lefty Tom Gorzelanny.

"My attitude is always to keep a positive attitude whatever role I'm in and help the team win some games," Marshall said. "We'll see what happens."
