It is an imperfect roster construction now no matter how you slice it (even though every team has similar imperfections.)
There are FIVE starting players who you may want to platoon in Gimenez, Sanchez, Clement, Barger, and Varsho, and of course you cannot platoon them all and given the current roster you can really only sensibly platoon Sanchez, so you have to hope Barger figures out lefties.
