Nationals' pitcher Shawn Hill had surgery on his non-throwing shoulder, completing the pair of procedures needed for him to return as the potential ace of the staff next season. The right-hander had a partially-torn labrum in his left shoulder repaired Thursday by Dr. James Andrews in Birmingham, Ala. Hill pitched most of the season with the injury, which occurred April 20 when he dived back into third base in a game against Florida. On Sept. 27, Hill had surgery to decompress the radial nerve in his throwing arm and to clean up scar tissue in his right elbow. Hill is scheduled to begin a throwing program in two months and is expected to be ready for spring training.
