That's a very good number but again--so is his size. Coaches are more likely to notice his size first, then notice that his exit velocity matches his size (meaning he knows how to square up the ball off a tee), But none of that matters unless he can actually hit live pitching. That's the most important thing and the other factors (size, exit velo) are secondary and in support of his ability to hit in a game.
I agree; there is a much better chance of him hitting and pitching at the D3 level. Coaches will still recruit position players (bonus if they can pitch) and pitchers (they don't really care whether they can hit). If a kid can really hit and he can also play adequately on defense, the coach will find a spot for him in the lineup. If a primary pitcher is good enough to be in the lineup everyday, he's likely also going to be on the field playing defense. And then pitch when needed.
