Blue Jays Reddit is of the opinion that Floyd is the 5th starter, while Sanchez goes to AAA to start and work on his not fastball pitches.
Sanchez's problem, as I understand it, is that he'll get behind on pitch count/give up hits or runners or runs, and thus turn to his heater while ditching his other pitches. In other words, until he gets his breaking ball and 3rd pitch (forget which one) down pat, he's essentially a one pitch pony. That one pitch is just stupid good. If he's a starter at this level,he won't improve his other pitches nearly as well if the pressure is on to win (rather than triple A, where the focus is "work on your changeup!" of whatever).
This is what I've read/gleaned from others, not through watching games or through stats...but has Sanchez's other pitches improved drastically? It's nice to reward a talented, hard working home grown guy, but is it worth having Sanchez as the 5th guy versus 3 months of focusing on increasing his repertoire?
