Washington, DC -- (Sports Network) - Washington Nationals pitcher Shawn Hill will miss the rest of the season due to swelling in his right elbow, the team announced Thursday.

Hill, on the disabled list since June 25 with right forearm soreness, experienced the swelling during a throwing program and plans to have the arm examined by Dr. James Andrews in Pensacola, Florida.

The 27-year-old was projected to rejoin the club by mid-September before this latest setback.

The right-hander missed the entire 2005 campaign while recovering from reconstructive elbow surgery.

For the season, Hill had a record of 1-5 with a 5.83 earned run average in 12 starts for the Nationals, who are mired in last place in the NL East.
