Yes, indeed. Rafaela in CF is a no brainer, The data shows he is farsuperior.
Abreu is a fantastic defender in an extremely difficult Fenway RF. He barely gets a chance to hit lefties, unless as RP'ers. He still needs to prove he can hit them to become a FT'er, but it's not like Duran has done well vs lefties in a far larger sample size. He's looked better than Abreu v L, but got worse, this year as Abreu seems to be improving. Since we have Ref, Abreu's weak area is covered, and it's not like we'd cut or bench Ref, if Anthony caused Abreu to be traded away.
To me, vs RHPs:
Abreu is our best OF'er (O+D) Duran is second and Rafaela looks 3rd, right now, but Anthony needs to be playing FT. I have no idea who to sit to get Anthony playing v R, but it's not Abreu.
vs LHPs, assuming Ref DHs vs lefties...
Rafaela is probably our best, followed by Anthony, then Duran slightly over the better defender in Abreu.
When you consider we face RHPs about 70%, this looks like a very close call, all around, with Anthony's ceiling carrying a lot of weight.
Tough call, but someone needs to go, if Yoshida-Ref DH.
