Hill, who has been on the 15-day disabled list since June 25,
was examined Friday in Pensacola, Fla., by orthopedic surgeon Dr.
James Andrews. Dr. Ben Shaffer, a Nationals team physician, said
Andrews discovered "bony buildup" behind Hill's elbow ligament
and recommended arthroscopic surgery to clean out the joint.
Before the surgery, Hill will see Dr. Tom Hunt, a hand and upper
extremity specialist, at the University of Alabama-Birmingham on
Wednesday. Shaffer said it is hoped the cause of the lingering
forearm soreness that has plagued Hill for much of his career can
be determined before the operation.
"It's a mystery. It's difficult to discern exactly what the
problem is ... It doesn't appear to be anything structural,"
Hill was 1-5 with a 5.83 ERA in 12 starts this season.
He missed the 2005 season after having Tommy John surgery, and
missed time in 2006 with soreness in his right elbow. Last season,
Hill was limited to 16 starts by a shoulder injury and a compressed
radial nerve in his right forearm.
