He's actually very athletic, even with the size. His hand-eye coordination and concentration are excellent (you can see him still focused on the ball in the first pic) and he can pick up the spin on the ball very early. I test him by throwing curves and making him call the pitch out as soon as he can.
There are a few kids on his team bigger than he is but he hits it harder than all of them. He's never had a formal hitting lesson. We've just focused on 2 or 3 key things for him to work on and it's worked great to this point. But for him to play high school baseball like he wants to he will have to continue to work to improve. The great thing is he is receptive and wants to learn. But I only know so much and so I think perhaps it's time for me to take him to someone who knows the swing better than me.
Thanks for your help.
