That's been my impression of him too from the MiLB times I've seen him. He seems a bit more shy/aloof. Not the center of attention extrovert type like the crew ahead of him (Adley, Westburg, Cowser, evem Hunnar). Nothing wrong with it either. One can hope it means he won't seek out a large market team...
Though the relational dynamics in the minors that can be a bit more 'stars' and 'scrubs' if that's how one views things...
