I believe the rationale, based on what I have read, is that Parra will be the main PH and having Schafer will allow RR flexibility to use Parra as such. If the choice is between Herrera and Schafer and the role is specifically being late inning OF replacement, give me Schafer. I hate that reasoning, and that logic. Braun can play CF for 3 innings if Gomez gets hurt and you need to pull him after Parra pinch hits. This is the same idiocy that keeps coaches from using their backup C as a pinch hitter. You can "Well, what if" yourself into not doing a LOT of things. The probability of them happening is pretty darn slim, however.
