Well, Maton is already off the roster with Didi also off the roster, so Didi not returning to the roster isn't likely to change that. They want Maton to play regularly in AAA and they wanted Williams' RHB off the bench w/ both OF being LHB.
Of course, if Didi ends up on the 60-day they may finally cut the cord on Jankowski or Joyce in order to have another IF glove, especially since Williams and Maton can play the OF too.
Though I also suspect if Didi goes on the 60-day SS also becomes a trade target.
