ANAHEIM, Calif. (AP) _ Philadelphia Phillies ace Curt Schilling had surgery on his right shoulder Monday and is expected to be sidelined until mid-May.

The Phillies, who announced Friday that Schilling had a problem with the capsule in his pitching shoulder, said the arthroscopic surgery in Wilmington, Del., was successful.

``Curt's range of motion was where they wanted it to be post-op. Today was encouraging,'' Phillies general manager Ed Wade said.

Schilling, 33, missed most of the final two months last season because of shoulder trouble. He was 15-6 with a 3.54 ERA and started for the NL in the All-Star game.

The Phillies traded for San Francisco pitcher Chris Brock on Sunday at the winter meetings to help take up some of Schilling's innings.
