start off slow then gradually go faster for more fun ;)
A 10 year old girl should pitch about 40-55mph.
It depends on how much they practice and workout. So anywhere from 45-55 miles an hour.
Should pitch at least 75 at high 80
Honestly, It depends on the girl. Some don't even pitch 40, while others pitch nearly 60.
boy- 100m in less than 17 girl- 100m in less than 20
Pitching a fast ball at 69 mph will not harm a 13 year old. A 13 year old should not be allowed to pitch a curve ball or any other pitch that may hurt his pitching arm. Curve balls should never be pitched by any boy under the age of 16.
