I coach a 13U traveling team made up of the best 12 and 13 year olds in the city of 1.2M where I live. The first thing you have to do when it comes to pitching speed is distinguish between "crow hop" speed and "live batter" speed. Crow hop is taking a few steps and launching the ball with maximum velocity, but without much regard for location control. The best 12 year old I coached could hit 70mph on crow hop, and I expect he'll be closer to 80mph when he's about to turn 14 years of age. No one throws that fast when pitching against a live batter, either in a game situation or in pens, because you need control to ensure you are efective in getting batters out. So, the 12 year old who crow hops 70mph will hit 63-65 mph with decent control in games. I expect when he's 13 he'll pitch with control in the low-mid 70s. This kid is tall and skinny, very dedicated to the sport, and has a competitive streak second to none. If he keeps it up, and avoids injury, he's solid college material.
an 11 year old should pitch in the range of 48-63
A 10 year old girl should pitch about 40-55mph.
Should pitch at least 75 at high 80
A 12 year old girl should be anywhere from 40-47mph.
anywhere from 45-60 mph if they are decent.
a 12 year old boy should be able to throw anywhere between 55-65mph
if your 8 year old does not pitch 35 mph or higher he's not that great. Just saying but 35 to 45 is about were a very good 8 year old should be.
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.
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.
they pitch from 65mph to around 80mph
