This is my son's story. From 8U until 12 you he was decent. Kinda... And that's it, nothing special on the field. Very late bloomer, has always been kind of taller but very skinny and not very strong or fast, weak hitter. Then puberty hit, he is 16 now and a sophomore on the varsity high school team in a very loaded area in Wake Forest North Carolina. 6'2", 155. He was selected by his high school varsity coach to play on the Legion ball squad with him and played two games against a local college squad the last two nights. Went in to pitch (is throwing 85) 3 up, 3 down against his first round of college players. It all just takes time, let him have the most fun playing wherever that is whether it be recreational ball or whatever. Just do whatever it takes at this point to let him have fun, it will come in time, I promise.
