Shawn Hill's arm problems continue. His elbow is suffering from overuse:

"It's gotten mildly worse, but it's not terrible," Hill said Saturday. "I'll treat it day by day, and they just want to make sure that moving forward we're not pushing through something that should be stopped."

Nationals manager Manny Acta said Hill will seek a second opinion Sunday at Duke University.

"I feel bad for the kid," Acta said. "For the last five years he hasn't been able to pitch a full season in the big leagues or the minor leagues."

Hill missed the entire 2005 season after undergoing Tommy John surgery.

Hill pitches well when he's healthy. He walks few batters, 2.5 per nine since returning from Tommy John surgery. The Nationals can use that kind of control over a full season.
