Peter Abraham just wrote that Farrell said 11 pitchers and that Bradley is out.
That makes sense because the 14 positions players are pretty easy to pick: Salty, Ortiz, Napoli, Pedroia, Drew, Middlebrooks, Nava, Ellsbury, Victorino, Ross, Carp, Gomes, Bogaerts, and Berry. Berry over Bradley because you can be pretty sure he will get a chance to pinch run late in a close game.
4 starters are even more obvious--Lester, Lackey, Buchholz, and Peavy.
7 relievers are tougher: Uehara, Breslow, Tazawa, Dempster, Thornton, Workman, and Morales--4 righties and 3 lefties--I think.
I theorized 6 relievers to make room for Bradley (or McDonald) and because the Sox don't have 7 good relievers. But I guess that's the point: when the bullpen is unreliable, the manager needs more options.
