Velocity is great but so much more to pitching.what pitches does he throw successfully? How is location, off speed pitches? You will find very good players at all ages that can get bat on FB. Location, location, location is so important. Who cares if kid is throwing heat if he throws too much where it can be hit. Being a P who is in control and can get ball where coach/catcher calls for it to be imo is most import.
