That really sucks, but on the plus side, we do appear to still have money available this offseason. We should be able to pick someone up.
Who knows if Boston would trade within the division, but Craig would be a fantastic target. JBJ could be a possibility too I suppose.
Guerrero would be a perfect target from the Dodgers, especially since he's blocked everywhere on that team, and can't be sent to the minors without his permission. He could also slot in to 2nd once Saunders comes back.
Ethier might be a good target as well, and he wants to be traded. If the Dodgers were willing to take maybe Navarro and eat 5M / year off Ethier's contract, that could work rather well.
As someone else said, Inciarte could be a good fit from the D-backs.
Bourjos from the Cards could also be a nice fit.
From our own team, aside from those mentioned, I could see Kawasaki as a potential guy too.
