If your son is a confident pitcher I don't believe there's a bubble to burst. As a couple of others noted, everything that matters is in front of him. Everything behind him is development.

BBfam's son is a great kid. He is an unbelievable teammate and a great competitor. He certainly wouldn't know his stats from his team because his team (and coach) doesn't keep stats (I don't like them and they are irrelevant in the development process IMO).

What I would say is that, although it's fun to have good stats, it's more important to concentrate on doing the right things the right way- attitude, work ethic, fundamentals, etc.

The process is more important than the result at this point. Keep working on the right things and the results take care of themselves. BTW- BBfam's son does that. He is very grounded and an absolute pleasure to coach.
