I think Didi's outlook is better than that. You'd get something for him picking up salary, or you might get a more useful sunk cost type piece if the money matches. You could also trade Segura (who you can't necessarily assume will be this good again) and hope Didi's bat bounces back as a 2B.
Gotta confirm there's a DH, make a decision about Bohm, and then address the rest of the infield from there. Who knows, maybe Freddy returns.
I guess if they wanted to be done with Herrera (and let Williams be the other CF) that would open up a spot on the 40 and the 26. But I kind of doubt they'll do that. And Kennedy and Gibson are already on the 40 - the space is there until Falter and Jankowski come back. I assume they will release Joyce, and then probably DFA Hammer or De Los Santos, unless they are finally ready to DFA Anderson or Vince. But probably not.
