To continue off of this....
Projected 25 man (assuming Lester is not here):
Buch, Lack, Demp, Doub, Morales, Webster (AAA?), Bailey, Uehara, Tazawa, Breslow, Miller, Aceves(AAA?) or Mortensen
Pedey, Papi, Vict, Iggy, Lava, Nava, Carp, Gomes, Ross, JBJ, Brentz, Middlebrooks, Bogaerts
The other 15:
(Webster or Aceves), Wilson, de la Rosa, de la Torre, Workman, Ranaudo, Britton, Kalish, Bard (?), Holt, Vazquez, Cecchini, de la Cruz, Linares, Vinicio
Possible players dropped from the 40 man via trade or DFA: S Wright, D Butler, A Hassan, B Holt, P Beato, or B Snyder
Possible players lost to rule 5: Linares, Vinicio, de la Cruz or one from the list in an above post.
Realistically, Ben is going to sign some players or trade for others. Let's assume this:
Ben takes Lester's option or signs a starting pitcher, even if just as insurance, in case Buch gets hurt or Doubront, Webster, Dempster or Lackey falter. Ben signs or trades for a coner IF'er, in case Middlebrooks and/or Bogaerts falter. Ben signs a 1B/OF'er in case Carp, Nava or an OF'er falters. Ben signs a CF'er in case Victorino or JBJ falter. That's 4 players added without looking to add a pen arm. I am pretty certain that Ben will add at least 3 players.
So, adding 3-5 players to the list above, you can see the crunch we will be facing. Now, it might be easy to make room for some of these additions by trading players like Aceves, Bailey, Morales, Mortensen, Miller, Gomes, Ross, or other 25 man roster players plus some of these: S Wright, Butler, Hassan, Holt, Beato, Snyder, Linares, Hazelbaker, de la Cruz, de la Torre, Vinicio, or Brentz.
It could look more like this:
+4 to 25 man roster:
Lester or FA SP
CF'er or Pen arm or vet catcher
and these other 21 (assuming Aceves, Mortensen, :
Buch, Lack, Demp, Doub, Bailey, Uehara, Tazawa, Breslow, Miller, (Morales or Webster)
Pedey, Papi, Vict, Iggy, Lava, Nava, Carp, Gomes, Ross, JBJ, (Middlebrooks or Bogaerts)
(+3) Brentz, Webster and Middlebrooks or Bogaerts are added to AAA (the "other 15") leaving just 12 slots for these players:
6 de la Rosa
12 de la Cruz
13 de la Torre
14 Bard (?)
15 Holt (?)
DFA or Rule 5: Almanzar, Linares, Vinicio, S Wright, D Butler, A Hassan, P Beato, Hazelbaker, Balcom-Miller, B Snyder, or others.
