Jeff Karstens is coming back to Pittsburgh for an evaluation after feeling pain in his right shoulder while throwing Friday, according to a report by Travis Sawchik of the Pittsburgh Tribune-Review.
Karstens had been rehabbing the injured shoulder with Triple-A Indianapolis when the setback occurred. Pirates general manager Neal Huntington told Pirates Prospects he would have a decision to make about what role Karstens would have when he returned from the disabled list but now it appears that decision could be pushed back.
