We already know the 4 starters, that Farrell will go with 11 pitchers including Doubront, and that Bradley and McDonald are headed to Florida to stay in baseball shape. So the likely roster is--
4 starters--Lester, Lackey, Buchholz, Peavy
7 relievers--Uehara, Breslow, Doubront, Dempster, Tazawa, Workman, Morales
14 positions players--Salty, Ortiz, Napoli, Pedroia, Drew, Middlebrooks, Gomes, Ellsbury, Victorino, Nava, Carp, Ross, Bogaerts, and Berry
And today's lineup against lefty Moore could be: Ellsbury, Victorino, Pedroia, Ortiz, Napoli, Gomes, Drew, Saltalamacchia, Middlebrooks. It's possible Farrell will move Middlebrooks up to 6th or 7th, but Gomes and Drew have a big experience edge, plus Middlebrooks hitting has tailed off somewhat.
