Reading the tea leaves of DD's latest comments it looks like they will probably only add one big bat - 1B or DH to be determined - with Hanley occupying the other position.Now, this may have been a smokescreen but I doubt it. DD seems to be a far from devious GM. He lays out a plan and is pretty direct about accomplishing it.
So - J.D. had to be the primary FA target , Abreu as the top trade target. Please stay far away from Hosmer. He's not a bad player but you don't want to pay 100+m for a "not a bad player". As for Santana, he has the QO albatross - he would have to have been considered prior to that being applied I think. Maybe Duda?
So - for me ..
Sign J.D Martinez as DH/4th OF
Hanley to 1B
Sign Nunez as supersub - replacing Holt on the roster
Regulars: Vazquez, Hanley, Pedroia, X, Devers, Betts, JBJ, Benentendi, Martinez
Bench: Nunez, Swihart, Travis, Brentz
I would be surprised if they add any bullpen pieces - maybe a loogie. As for SPs, I could see Fister brought back considering the health of ERod and Wright.
