Volquez scheduled for elbow surgery

CINCINNATI -- Cincinnati Reds right-hander Edinson Volquez is scheduled to undergo elbow surgery Monday.

It was not immediately clear if he will have a ligament-replacement procedure, known as Tommy John surgery.

On the disabled list since June 2, Volquez, who made just nine starts this season, could throw only 20 pitches of a simulated game scheduled for 80 on Friday before complaining of tightness in a muscle.

Volquez is 4-2 in his second season with the Reds after being acquired from Texas for outfielder Josh Hamilton before the 2008 season. Volquez was Cincinnati's only All-Star last year, which he finished with a 17-6 record.
