Two years after his surgery, my son completed his high school athletic career with no lingering elbow problems. He finally got into lifting weights and the lifelong contact hitter suddenly discovered that he had power (2 home runs on senior night were special). He made first team all state for private schools. Rather than continue his baseball career at a D3 school, he chose a large state university and entered the Air Force ROTC, so I think he has joined a very good team and will do just fine.
Good wishes to all of you baseball parents. I hope you all treasure your sons' time in high school baseball; it goes quickly!
