I wouldn't quite see he should be that half of the platoon, but with Braun/Thames at 1b, he would clearly be a better option as an emergency 1b. With Braun and Thames you have two guys who can be borderline regulars at 1b, and one of them will be available to pinch-hit almost every game. There's no reason to waste a roster spot on such a limited guy like Aguilar as a 3rd-string 1b and pinch-hitter. Vogt can be the emergency LHB 1b and Perez the emergency RHB 1b. Both of those guys are infinitely better uses of a roster spot because of what else they can do. Perez's value on defense and the basepaths is so much better that it could almost close the gap with Aguilar even regardless of the fact that he can play 4 other positions well. You can probably even add 2 more positions that he plays about as well as Aguilar plays 1b. They need the extra reliever, period. Suter (or Hader) won't give you many innings per start, and guys like Anderson, Davis, and Chacin aren't exactly big innings-eaters either. Woodruff will probably have an innings limit as a young player, and Nelson will too when he comes back. This is one of the easiest offseason choices they will make. My post was made with the assumption that Santana gets traded
