PITTSBURGH (AP) _ Pittsburgh Pirates reliever Rich Loiselle had reconstructive right elbow surgery Thursday and will miss the rest of the season.

Loiselle, who had 29 saves as a rookie in 1997, threw three times on the sidelines last week but had pain each time. He was forced to cut short his final workout due to the pain.

The surgery was performed by Dr. James Andrews, the Birmingham, Ala., specialist who has operated on a number of major league pitchers.

Loiselle, 27, began the season as the Pirates' closer, but lost the job a week into the season. He was 3-2 with a 5.28 ERA, 14 strikeouts and nine walks in 15 games before going on the disabled list May 8.

The Pirates hope Loiselle can pitch again by the start of next season.
