A 15-16 year old Sophmore has the advantage there. The body is still young, and able to repair itself easier. Just wait, soon you will be an old fart like some of us, and wonder how someone can throw 50 pitches, without needing a new arm... lol

Not to mention, that was 160 pitches, then a week later throwing 130. A lot of the time, Major league pitchers will throw 2-3 games in one week...
