He seems to have good form, form that's sustainable. I really like his complete pithing cycle - he stays with the pitch all the way through his release phase.
By the way, one of the reasons why his pitch is so hard to pick up sometimes, is that his finish has him down, and not popping up during his release. This downward bending into the pitch, actually blends his body as background to the incoming ball, thus giving the batter a slight focusing reflex. This focusing reflex is the batter's eyes uncontrollably - just for a split second, on him then on the ball, and possibly repeating itself. This focusing reflex is one of the reasons why a pitcher can not have a white sleeve or similar item/apparel on his pitching arm/hand. In fact, the uniforms for a club I was on had to reorder because the emblem on the upper right sleeve had a logo on it that looked like reflective tape when under the lights during night games.
Overall he looks good. What is his repertoire? Would you mind telling me his height/wt/age and what part of the country he lives in? If this is too personal for general posting, you could PM me. I'd be very interested in passing that along. He looks mature, good presence, and worth looking at by others.
