Well, off the 40 man.
He is an easy choice to DFA at some point, and he is likely to go unclaimed and he can then be sent to Worcester. He does not have the service time required to refuse assignment and declare free agency, unless that changes in the new CBA(which is possible, but very unlikely).
pBest case scenario for Gray is he becomes one of those guys every team wants but no one wants to commit a 40 man roster spot to, so he goes through a long, repetitive cycle of being claimed and DFAd by several teams and gets mention MLBTR weekly…
