Cole Hamels...Dead Arm?

[bobnerns]

Cole Hamels said he was dealing a dead arm during Friday's start against the Nationals.Hamels showed diminished velocity Friday while allowing three runs on six hits and four walks over five innings in a loss to the Nationals. While the southpaw said he wasn't dealing with any pain, Phillies manager Charlie Manuel said he was having trouble getting loose before the game due to "shoulder stiffness." Be sure to track his status over the next couple days

Is this something to be worried about? My H2H league's playoffs start tomorrow and Hamels is my ace.

Hamel's BP session did not go well today. He is being placed on the DL.
