Size vs speed


What’s the average velocity for a 10 year old boy? He is 4 ft 3 in and weighs approximately 60lbs. His fastball averages 50-55 mph


This chart should help you.


One thing here, his fastball isn’t that fast


And he’s also 10 but is the size of an 8 year old. He has something the other kids in his age group don’t have and that’s accuracy and control. You can throw fastballs all day, but without those two things your fast ball isn’t shit


You basically answered your own question… It doesn’t matter. He’s 10. I’m betting you are just curious, and that’s fine, but seriously don’t worry about it.
Being able to move the ball around, hit his spots and change hitters eye levels is far more important to learn
young than velocity. He’ll grow, hopefully. You need velocity, but not at 10. And it can come from training and dedication.
Charts, especially those that come from some Velocity Camp, often measure speed out of hand. On the big diamond that on average translates to an 8 MPH drop by the time it get’s to the plate. Don’t know what it is on 46 or 50 ft distance, cause nobody cares. Pitchers who succeed have carry, the ability to maintain speed through the plate.
Some kids can throw really hard at a young age, whether it be size or just naturally great mechanics and separation, etc. Everyone get’s all excited about them because nobody can hit them, but that doesn’t always translate to later down the road for them. Sometimes, not always. The kid who maybe doesn’t throw as hard and gives up pop ups and ground balls that are hits now, are outs when he’s older and he throws less pitches per inning. A successful pitcher doesn’t need to blow hitters away, it helps, all those swings and misses, but those that do that are called short relievers.

I bet I can guess the scenario with your son, often the team starts a real hard throwing stud, but by the third inning he’s gassed, and has given up several runs on walks and steals and his teams down 5 runs, etc. They go to your son, he calms everything down by throwing strikes, get’s some weak ground balls, a pop up or two and a strike out, next thing you know your teams back in the game. Worth his small weight in gold. But often goes unnoticed cause everyone is still awed by the first kid.

Seriously, don’t worry about it, he’s 10, he’ll grow. :wink:

PS. Sometime go watch the older kids, a legion game or high school… you’ll see pitcher that have real gas, and they still get hit hard, now days everyone can hit… not everyone can pitch.


Actually with my son it’s the opposite he’s their main man. He doesn’t run out of gas quickly and he’s consistent. His coach is happy with his change ups and trusts my son’s decisions on the plate. You were right though it was more or less curiosity. His coach is impressed because he freezes hitter at the plate and goes with his gut and knows when to throw a change up. Another thing is my son listens to his coaches and takes everything in and applies it. This is his second season as starting pitcher for Allstars and it’s hard not to get excited when you see him play especially for a kid who hasn’t been playing that long compared to his teammates. He started playing at the age of 8.


That’s the thing though. What u do at age 8 doesn’t mean anything. You keep throwing him like he is expect tj.


Here’s some good advice…don’t listen to Salty… you probably weren’t anyway.

Pitching in All Stars is nice. Little league has rules for pitch count. Make sure you follow that.

When it comes to Travel ball, be careful not to overwork the young man. Teams that throw him a lot, and he plays little league or what not, can cause over use. Good travel teams have lots of pitchers and the kids often only throw 3-4 innings max. It is not uncommon to see kids swap out every two innings.


Lots of good advice here (for the most part). It’s so hard just to sit back and enjoy watching your kid play at this age. You start getting so excited about getting to that next level that you miss out on what’s going on now. I’m not saying this is happening with the OP, but I’ve seen it and been guilty of it myself.

The key for kids who have success early on is to make sure they continue working hard on their skills (hitting, fielding, base running, pitching, etc). I know quite a few kids who had early success and didn’t work as hard as the other kids and got passed by somewhere between their freshman and sophomore years in HS. Keep getting better every day because there is always going to be someone gunning for your spot!
