I’m on board with the responses. As a lefty D1’s are probably looking for him to hit 87/88 consistently. If he was right handed it would be 90.
It’s great your son is dominating the hitters he ‘s facing. It’s good for his confidence. But the college coaches aren’t necessarily gauging him against those hitters. They’re looking at his tools and trying to project if he will get college hitters out.
And you’re right about if he were 6’2”. Is he done growing? Are his growth plates still open?
This summer is only his post soph summer. Relax.
It’s fun to tell others to relax now that my kids are done playing. . But the reality is it all works out for any kid with the will to make it work.
