Paul, hey, I also just learned about the Speed selector from you. Thank you.
The videos work now. I think your son’s mechanics are decent, his speed also looks good. He is a little on the skinny side to be effective. He will also need to grow taller to give him more arm spans and the height of his recent. I like that his glove tucked into the chest and his chest was down after the pitch.
Just need to keep practice and grow. He will get to shine.
Good luck and enjoy.
