At best, he’s a mid-season call up. He’s not on the 40 man roster and his minor league deal guarantees Pawtucket to start.
If the Sox deal Bradley - which I would call unlikely - that could clear up a bench spot for Swihart. Although I would expect the Sox to get a OF//DH type before the season, because I don’t think the plan is to make Steve Pearce the everyday DH with JDM moving to LF. At least I hope not. And I don’t think Swihart gets that role, either...
