We are going to have a ridiculous bench next year if Moncada cracks the roster, which there's no reason he can't. If Shaw is sitting on the bench because there's no better place to put him, then our 4 man bench is probably one of Vazquez, Swihart or Leon, plus Holt or Hernandez, plus Young, plus Shaw.
Most likely as follows:
C: Leon (he's earned the right to at least start next year as the presumptive starter, whatever happens)
1B: HanRam (I'm satisfied with his performance, if he loses that job it will be to Shaw)
2B: Pedroia
3B: Moncada (I think he's ready, the question is, can Shaw make a case for making Moncada wait?)
SS: Bogaerts
RF: Betts
CF: JBJ
LF: Benintendi
DH: rotational, probably mostly Young and Shaw
Bench UT: Holt
Bench C: Vazquez (Swihart, with the higher offensive potential, gets his swings in in the minors until he's needed)
Bench IF: Shaw (if we crowd Shaw into the bench role with Moncada and Hanram starting, we'll have the best depth at the corners we've had since 05 when Kevin Youkilis was on the bench)
Bench OF: Young
If we don't make a big acquisition to play DH full time, then we have 2 opportunities that could both be worth our time
1: HanRam as full time DH. He's our biggest defensive liability, replacing him in the field with a defensive asset (Shaw) might be worth our time
2: Young/Shaw platoon at DH. If HanRam feels he needs to play defensively to be effective, and this is a stunt I feel he might pull, running a platoon of our best platoon hitters might be the best way to go. Neither Young or Shaw should be given the DH spot on their own, but a platoon of the two has potential to be highly effective
Of course all that fancy schmancy overthinking goes out of the window if Ortiz decides to play another year. I don't think he could have expected to play this well, I'd love to have him back if he's willing to come back.
