Pretty sure he's going on a rehab assignment soon. He's done 1, if not 2, sim games in the last weekish. Again, he hasn't pitched since 2016. Even if he goes on the rehab assignment in a week, you don't miss almost two full seasons, go throw 20 innings in A ball and then come up in a pennant race and help/make a playoff roster. The smyly signing was good, but for reasons beyond 2018. If he can be pitching by middle of August in the minors or MLB he absolutely could make the roster if he's throwing well and they've said so much as that when he signed and as he's progressed lately.
