When at full strength, I think my bench would be: Amaya, Peralta, Cooper, Mastro, Tauchman
That may be too many lefties on the bench, but we're a bit right handed in the lineup. I wanted to slot Peralta in for Tauchman entirely, but someone has to back up CF. But Peralta is my primary LHH pinch hitter & DH when not resting guys. Tauchman for OF defense. Mastrobuoni for pinch running & IF defense. Cooper is DH vs lefties or short-sided platoon 1B.
