I was pretty impressed with Hall today and he moved up a few notches on my prospect list. Decent velocity on the fastball with sinking movement, ultra-simple delivery. Like I said, the slider definitely had its moments, with sometimes nasty tilt. As long as he continues to pound the bottom of the zone and refine his chanegup, he'll be more than fine on the mound. Just about the only times the ball was hit hard was when he left a pitch up in the zone. I wouldn't worry about the K rate yet, as long as the BB rate stays down. If he adds/gets back to his old velocity while maintaining the sink on his fastball, he'll become a very good prospect very quickly.
