An average 11 year old can pitch from 30-45 mph and 50 mph. I pitch 65 mph and I'm 11 but I realized that I pitch pretty fast compared to other league members. would say the average 12 year old pitches about 55-65 mph with 65 being the upper range for tournament players. In the Little League World Series you may see a kid pitch 70+ â¦ mph but that is exceptional.
