I know most of the topics are about older kids. I have a 9 yr old, will be ten the end of March. He's around 5 ft tall and weighs roughly 85 lbs. I have a radar gun (he has older brothers) and have clocked him at 52-53 mph. So, I'd say for his age and size he throws pretty hard. My concern is with him throwing as hard as he does is injuries down the road. His older brother, now a senior just had labrum surgery on his throwing shouler. He mainly played o/f, but also pitched some relief for the H.S and Legion team. Any recommendations as far as things I should be doing with him as far as physically, but also with how often he pitches. We live in North Central Arkansas, so the weather doesn't allow for year round ball like my older one played when we lived in So California. But, I do get em out and throw when the weather is nice after the season during fall and winter. Thanks for any input.
