1. I am hoping for a bullpen addition or two, but right now the Sox have Barnes, Brasier, Hembree, Workman, Thornburg, and Johnson and (if healthy) Wright.They also have Poyner, Brewer and Lakins on the 40-man roster and still have one open space.
2. Hopefully Pedroia can play. This surgery can go either way. It ended the career of Grady Sizemore prematurely, but it also didn't affect Justin Turner much at all.
3. It looks like Vazquez and Leon split catching duties, which is fine with me. Swihart falls into the category of supersub utility players, of which the Sox have 4 if you count Pearce. If Pedroia cannot go, one of Holt or Nunez probably handles 2b, leaving the team at 25 active players. If Pedroia can play, someone has to go. The only player with an option left is Holt, but I really doubt he gets demoted. So maybe Swihart is moved or released at some point?
Chavis and Lin will both play at some point this year as needed for injuries. But that's probably the only way they make the 25 man roster at all this season. Dalbec is not even on the 40 man roster yet, and isn't likely to be the next player added from within. Erasmo Ramirez probably is, as he has an opt out but if he pitches like he is capable, he might be in the pen. Durbin Feltman is another player likely added before Dalbec, but I do think they want Feltman to get some innings above A-ball first...
