At the same time, you seem to be making this more complicated and more simple (comparing 2015 OPS figures) than it actually is. Sano will get days off from RF, that is sure. Plouffe will get days off from 3B, that is sure. On those days that Plouffe gets his days off, I'd like the option to shift Sano to 3B and use Arcia (or Kepler) in RF, OR you could use Nunez at 3B if you like. If Sano gets "days off" at DH, you'd have the further option to use Vargas or Park in his place at DH, OR you could still just use Nunez at 3B. And if you've got Nunez at 3B, you'd have the option of pinch hitting for him and shifting Sano there, even if Plouffe was unavailable. If you've got Sano at 3B and a late lead, you'd have the further option of shifting him to 1B or RF or wherever you were willing to de-prioritize defense. The point is, options. You could see who is hitting best (and/or fielding best) at the time and go from there. If you really trust the 2015 numbers, you might be right, it could be Nunez. But it might not be, the complete records of Arcia and Park make a compelling argument otherwise. I've understood since at least November that Sano wasn't a big priority at 3B, and I have no problem with that. The idea that he's only an emergency option, what Molitor said yesterday, seems unwise, though.
