Punch, I personally witnessed a few 10's throwing over 50 mph. Not saying they did it all the time. I know the Classics, Hawks, Laser Red, Inferno and I believe a couple other teams had girls throwing over 50 mph last year. There were several girls in 11u that threw over 50 mph as well. Doesn't mean a whole lot unless you have movement and accuracy to go with it, but they're out there.
