Moore could just use this as leverage to get a bigger AAA salary. He would also get $100K automaticallly though I think him triggering the opt-out might close that off already (and, in fact, maybe it requires the Phillies to either DFA him or put him on the 40, no other negotiated option).
But they could also just put him on the 40 and DFA him in a week. If there's really another team out there ready to give him a spot, good for him.
It seems like what the Phillies like about Moore over De La Cruz is he can play the infield, but so can Kemp.
