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.

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.
The year was 1991
38-45 mph
A good time is anything under 14 minutes
average pitcher-70 mph; good pitcher-75 mph; stud-80+mph
In my opinion, 12 year old shouldn't pitch the ball fast. Hard but not fast! In other words, don't hold back but don't strain either. You have plenty of time to develop speed once your body is developed. Concentrate on good fielding and ball contact when batting and your set for huge future in fpsoftball. A glove is 10 times better than a bat or a pitch.
