I think not playing Ender has probably been blessed, considering that I've seen it rumored that it was not Snitker's decision to start Keuchel game 1 of the NLDS, and he's been using Nick correctly so far. It's likely his decision here to not play Ender, but if the organization had any problems with it, I'd figure they'd have already stopped it.
The only thing that would be confusing here is if you're choosing to not play Ender, why not try Pache. Maybe that time will come soon though.
I can't imagine Newcomb's leash is going to be much longer either.
