TRAINER'S ROOM

Red Sox: RHP Clay Buchholz had a platelet-rich plasma injection in his right elbow from Dr. James Andrews on Wednesday. Buchholz was placed on the 15-day DL with a strained flexor muscle on July 11. He will be shut down for a while and the Red Sox aren't sure when he will resume baseball activities.
