Waguespack (shoulder) has been shut down from throwing due to a lower-back issue, Steve Carney of StPeteNine.com reports.
Waguespack has been shelved since May 6 due to inflammation in his right shoulder but was given the green light June 24 to begin a rehab assignment. However, he's picked up a lower-back injury that will require him to be shut down for an unspecified period of time.
