He didn't do well last year at a lower level, presumably due just to lingering effects, so starting him at high-A wasn't controversial in my book. Let him achieve some comfort and success to start out. But, as I said in a different thread, I think moving him up quickly this season could easily be in the cards, for exactly the reasons you state. A cameo appearance in AAA near season's end, if all has gone well and if an innings limit allows it, could still have him knocking on the big club's door by the middle of next year.
