But do you really think that is what the gap would actually be? ZIPs are great and all, but I'm guessing when the 2016 version comes out, there might be a more sizable gap between the two. Real or imagined, I would prefer not to give away ABs late in games that might end up going to extra innings and I think it's a safe bet there's less of a chance that happens with Shaw than it does with Marrero. Which is to say nothing of the fact that Marrero has never even played 1B. Projecting him to be a plus defensive player there might seem logical, but it's less than guaranteed that he has a sizable edge on Shaw to begin with.
I believe this is now the fourth time I've stated clearly that if either Ortiz or Hanley were to need to miss more than one game, the logical and appropriate thing to do is to play Shaw during the absence.
Any talk about "giving away at-bats" completely misses the point that the job of a defensive specialist is only to play the best defense possible, and if he's coming to bat at all, it probably means something else has gone wrong. But it's probably not something gone wrong that would be likely require the Sox just keep throwing Marrero into the batter's box game after game, while a superior option is readily available.
All I'm suggesting, is that the Sox should break camp next spring with Marrero as the 25th man on the bench, who can be expected to get about 30 PA over the course of the first 50 games, in his limited role as Hanley's defensive replacement.
Hitting-wise I don't expect there to be any relevant gap at all, as it impacts to the Sox' early record. And I say that even though I really do think Shaw would easily prove to be a better hitter than Marrero over 500 AB.
But 30 PA over two months is entirely statistically meaningless. Anything could happen (see JBJ, Aug. 2015). Either Shaw or Marrero could hit 5 HR over those at bats, and either of them could go 0-30.
But chances are, neither of them would do either of those things, and instead each guy would collect a few singles, take a few walks, strike out a few times, and maybe hit a double or home run.
The Sox will staff the bench with a pinch-hitter for JBJ, but to start the season that will probably be the acquired RHH vet. The Sox will staff the bench with a utility player, but to start the season that will probably be Holt (who can also PH for Castillo). The Sox will staff the bench with a second catcher, whomever it is. So the only remaining "job" to be done that reasonably foreseeable, at least to me, is Hanley's caddy.
Marrero is a great glove SS and played really well at 3B down the stretch. He certainly looked smoother than Shaw in the field to me. And should any events such as injuries or trades or extended suckitude occur, it's not like I'm suggesting the roster be carved from stone. I expect the bench to evolve along with the Sox' needs.
I'm just suggesting this move because I think it would help the Sox build the best team, and not just trying to fill the roster with the best group of individual players, regardless whether the different parts fit together.
