MacDougal undergoes hip surgery

Nats closer expected to be ready by Spring Training

WASHINGTON -- Nationals closer Mike MacDougal had arthroscopic surgery on his right hip on Tuesday. The surgery was performed by Dr. Marc Philippon in Vail, Colo.

Philippon is the same doctor who performed similar surgery on Yankees third baseman Alex Rodriguez earlier this year.

MacDougal should begin a throwing program in six to eight weeks and should be fully recovered by Spring Training.

MacDougal had problems with his hip since late August, but pitched until the end of the season. In 52 games for the Nationals, MacDougal had 20 saves and a 3.60 ERA.
