Philadelphia Phillies pitcher Kris Benson has been scratched from his rehab start because of tightness and soreness in his right biceps muscle.

Benson is attempting to work his way back from rotator cuff surgery, which he had the prior offseason while a member of the Baltimore Orioles.

The Phillies picked up Benson in the offseason, hoping he could be an effective starting pitcher sometime around the All-Star break.

Philadelphia could really use a No. 5 starter given the struggles of Adam Eaton.
