Diamondbacks Manager Torey Lovullo gave his first press conference today, speaking for 25 minutes. Within that time he revealed that Zac Gallen was feeling shoulder discomfort during his off season throwing program. Unable to work with team doctors he had an MRI on his own, and that revealed Bursitis in the shoulder. That link mentions “impingement syndrome”, which apparently can lead to rotator cuff tears if not allowed to heal properly.
Torey said that Zac would be throwing a bullpen thursday, and that he is behind in his progression. He stopped short of saying he would miss opening day, but this is not the way you want things to start.
