I keep hearing that they want to pursue an extra infielder and a centerfielder. The way the team is constructed right now, the math won't work. And trading a pitcher won't make it better.
We can assume they carry 12 pitchers and 2 catchers. That leaves 11 spots.
Victorino, Bradley, Gomes, Nava, Ortiz, Napoli, Pedroia, Bogaerts, Middlebrooks, Carp make 10.
That leaves one spot, so if they resigned Drew and rotated him, Middlebrooks and Bogaerts they would not be able to bring in a righthanded hitting outfielder like Gutierrez or Davis.
Unless they traded someone. And that does not mean Middlebrooks, because they would still need a backup infielder, like Holt. It would have to be an outfielder. We know it's not going be Victorino. It is probably not Bradley, because the whole point of a RH hitting outfielder is to complement him, not replace him. Trading Bradley would mean a bigger deal, like Kemp. That leaves Nava, Gomes and Carp.
It is unlikely that they would trade Nava. He is worth a lot more to them than anything they could get in return and he is just a pefect guy given his attitude for this team. I don't think they would get much for Gomes. Again worth more to them. Carp possibly but he is just 27 years old and looked like he did his first year in the bigs. If anyone, it would be him to trade and open that spot.
So what is better, having Carp or Gutierrez or Davis. Might they be better served to slide Victorino over when they need to and put Nava in right and still have Carp and/or Gomes in left.
The other path is not to have another infielder, but that is cutting it short. Right now, they have no backup shortstop for Bogaerts. No backup for Pedroia either, but that isn't critical, since he never comes out. If he got hurt we are talking innings and middlebrooks can move over for a couple. But then who plays third for those innings, probably Gomes. They would make a move the next day.
As I see it, if Drew comes back, they have that rotation and mIddlebrooks is the in game emergency man for Pedroia. If he doesn't and they bring up Holt, he can play all three as a backup. There would be no rotation. It would be Bogaerts and Middlebrooks straight out.
The point is the math doesn't work for an infielder and an outfielder.
