Scott Olsen of the Washington Nationals has scheduled surgery Thursday to repair the labrum in his pitching shoulder and will miss the rest of the season.
Olsen, 25, was examined Monday in Birmingham, Ala., by noted sports surgeon Dr. James Andrews, who recommended the season-ending procedure.
It will be performed by Nationals physician Dr. Wiemi Douoguih at Washington Hospital Center.
Olsen made 11 starts this season, posting a 2-4 record and a 6.03 earned-run average in 62 2/3 innings pitched.
The promising left-hander is 33-41 with a 4.77 ERA in 113 appearances (112 starts) since he broke into the major leagues with the Florida Marlins on June 25, 2005.
