Nationals outfielder Bryce Harper will be out until July after tearing ulnar collateral ligament in his left thumb and will have surgery.
Harper has already missed time this season with a strained quad muscle. The 21-year-old outfielder missed 44 games last season with a knee injury from running into the wall at Dodger Stadium. To replace Harper, the team will look to Nate McLouth and Kevin Frandsen who have each started a game since the young star injured his thumb.
Harper was hitting .289/.352/.422 with one homerun, nine RBI and and a stolen base on the season until the injury.
