NEW YORK -- Rehabbing Pirates starter Charlie Morton threw a bullpen session as scheduled on Friday and emerged with no pain or problems in his right shoulder.
Morton, who underwent Tommy John surgery on his right elbow in June, had experienced tightness in his shoulder after a rehab start.
The next test of the elbow is undetermined, but the Pirates anticipate no problem with Morton's elbow.
