The Red Sox might be a team to deal with for a lefty reliever, with Miller, Breslow, and F. Morales.
Their bullpen is overstuffed right now, with 7 righties (Bailey, Hanrahan, Uehara, Bard, Tazawa, Aceves, and Melancon) along with the 3 lefties. Figure they go 5R & 2L. I don't know Bard's option status, but I think Bailey might be the only other guy with options.
I'd like Morales for the Nats as pitcher capable of multiple roles.
