Actually, he hasn’t been able to maintain his velocity deeper into games, losing velo after just 3 innings or so, which tells me he’s far from starting for the big-club even if he continues to make command improvement.
I think the focus will be on building-up his stamina which could take time, maybe 1-2 years. He can’t start out at 97-100, and sit 94-95 by the 4th inning if he going to eventually rotation.
Hes worth taking our time with.
