Right-hander Zac Gallen has a hairline fracture in his right arm, an injury that seems certain to sideline him for Opening Day but still was received as good news for a Diamondbacks club that had been bracing for the worst.
Gallen’s injury was described a day earlier as “forearm soreness,” a term that often can be code for ligament damage, but the Diamondbacks said Tuesday their prized young pitcher does not have any ligament, tendon or muscle issue in his arm.
Instead, a battery of tests, including an MRI, an X-ray and a CT scan, revealed an injury the club described, in clinical terms, as a “hairline stress fracture of his right lateral forearm at the radial head,” manager Torey Lovullo said.
