Just like to update, he is now 5'9" and 123lbs, we went to our customary tryout for his mid level club team. He was cruising at 76-77 on his fast ball and -10 - -12 on his off speed. Clocked 7.07 in the 60.
This year we did little of weight lifting, squats and dead lift, not more than 100lbs, little bit of plyometrics, a little long toss and cardio.
He is 5'11 and half, almost 6', weighs 135!!! Doctors says he had a late growth spurt and he may grow another 2-3, we will see. But he is throwing 78-83, consistently in the 80s, one tryout he was clocked 84, I didn't see it so. We are trying to gain weight. He has try this and that on his own. If anyone has some ideas, I would love to hear.
