Chewy... We play with 60 foot baselines starting in 8u in ASA, USFA, and USSSA travel ball.
Ha. Yes. About every year.
I think that 3.25 is decent speed for a 10U girl, to first base. Any faster than that and you will notice that she is fast.
You better teach them to hit, if they are really slow.
I saw a lady out exercising yesterday and she was about to twist herself into the ground. I don't understand why some females twist at the shoulders instead of driving their arms forward like a locomotive.
