10 days to go, and everyone is circling each other but almost nothing has happened. It is hard for me to find a deal that makes sense for both NY and the other team, but here is one, I think.
Robbie Ray to NY
Clint Frazier, Jordan Montgomery and a third piece to ARI
ARI is at 50-50 currently and a few games out of the wild card, but they are desperately thin in the outfield, playing Jarrod Dyson and Adam Jones and Tim Locastro in the corners currently with no good prospects anywhere near. Frazier would fill a huge need for them immediately and long-term and Montgomery can replace Ray by the start of next season at the latest (maybe sooner) as he is very close to being back from Tommy John. Ray is only under control through 2020, Frazier and Montgomery both through 2023.
Those two by themselves are more than enough according to baseballtradevalues.com (Ray-22.9, Frazier-19.4, Montgomery-6.8) but Cashman has so much depth that he could afford to throw in a third piece if needed. This could be a MLB-ready reliever (like Gallegos who they sent to STL last year), one of their many utility infielders who are blocked (Estrada, Wade, Valera), one of their many high-ceiling pitching prospects, or one of their many tempting teenage position players.
Teams aren't always rational about their own players, but that seems like it makes sense all around. Make it so, Brian.
