I think the 2 D and 1 F votes were cast by Masterson, Hagadone, and Price.

I voted B. I like the move fine, but I don't see huge upside unless Tek gets hurt or really goes in the toilet offensively. I think people are over-rating Martinez's offense somewhat. .850 OPS from a catcher is excellent, but the same from a 1B is only decent. My guess is that he only catches 3 times per week for us, so that reduces the value of the trade a little, imo. It sounds like he is only an adequate defender at both positions (his catcher ERA the last 3 years is 4.01, 4.31, 5.78, compared to Shoppach's 4.16, 4.37, 4.84). To evaluate where the gains come from, I think it's most helpful to looks at L/R OPS splits.

Varitek:
'09: vsL: vsL: .914; vsR: .753
3-year: vsL: .777; vsR: .710

Martinez:
'09: vsL: .809; vsR: .842
3-year: vsL: .827; vsR: .840

Lowell:
'09: vsL: .951; vsR: 761
3-year: vsL: .812; vsR: 842

Ortiz:
'09: vsL: .771; vsR: 740
3-year: vsL: .885; vsR: 1.066

Youkilis:
'09: vsL: 1.063; vsR: 913
3-year: vsL: .854; vsR: 874

Baldelli:
'09: vsL: .817; vsR: 573
3-year: vsL: .822; vsR: .800

Laroche:
'09: vsL: .643; vsR: .830
3-year: vsL: .790; vsR: .872

Kotchman:
'09: vsL: .660; vsR: .808
3-year: vsL: .785; vsR: 751

Gains vs LHP: None? An argument could be made that there would be a gain replacing Lowell or Tek with Martinez, but since I don't think it will happen, I don't think there's any gain there. Unless Lowell and Tek will be benched entirely, it makes sense to play them vs lefties. This means VMart sits unless he DHs in place of Ortiz, which could be a gain or loss depending on who Papi really is at this point. Regardless of whether it's a gain or loss, it appears the same gain/loss could have been achieved by platooning Ortiz with Baldelli.

Gains vs RHP: Ortiz and Youks should play, so the gains to be had here are by replacing either Lowell (largely because of his defensive problems this year) or Varitek. Against RHP, Laroche has similar offensive numbers and is probably a similar defensive 1Bman, so I think the gains of Martinez over Laroche against RHP is small. Most of the gains from the trade, therefore, come from Martinez replacing Tek against RHP. I would guess this happens about 3 times per week if they DFA Kottaras, and 2 times per week if Kottaras stays.

Overall, then, I see the primary gains as 100 to 150 OPS points at one position 2-3 times per week, plus some very nice injury protection depth, plus additional ability to keep Tek fresh. We gave up some real value, but nothing extreme. Looks like a B trade to me.
