ANAHEIM, Calif. (AP) – Angels slugger Troy Glaus had surgery on his right shoulder Friday, an operation that might sideline him for the rest of the season.

Glaus’ arm will be in a sling for the next 10-to-14 days before he’s examined by team physician Dr. Lewis Yocum, who performed the operation.

The three-time All-Star third baseman and 2002 World Series MVP is scheduled to begin physical therapy after that. Anaheim said no timetable has been set for his return, but if there is one this season, it almost surely won’t happen before September.

Glaus, 27, was placed on the 60-day disabled list Tuesday, a day after Anaheim announced he had decided to have surgery because, he said, his shoulder “hurt on every swing.”

“If the pain was bearable, I would deal with it,” Glaus said. “But it got worse. We’ve done everything we can do to try to make the pain go away, and it’s not. This is the right decision.”

Glaus was leading the AL with 11 home runs when he was forced out of the lineup. He had been the Angels’ designated hitter recently.

Glaus is hitting .296 with 28 RBIs in 29 games. He is in the final season of a four-year, $23 million contract, and eligible to become a free agent after the season.

The Angels took the majors’ best record into the weekend despite a number of injuries to key players. Outfielder Garret Anderson, designated hitter Tim Salmon, first baseman Darin Erstad and reliever Brendan Donnelly already were on the disabled list.
