My future brother in law playing in the State Tournament in high school. They faced a kid who weighed all of 3 bills, pitched some major heat and hit over .600. It was a long time ago, but I could swear he didn't even have to run the bases because they were allowed to sub for him to run the bases without taking him out of the game - like he batted for himself but had a designated runner rather than a designated hitter. It was an unreal advantage. They lost of course but put up a hell of a fight.
