Average exit velocity by age

For what it's worth, a quick Google search yielded the below:

D1 - Bat speed: 64 for slappers / 72 for hitters
D1 - Ball exit speed: 63 for slappers / 69 for hitters

11th grade - Bat speed: 66 (no info for slappers) and ball exit speed: 63
10th grade - Bat speed 67 and exit speed: 63
9th grade - Bat speed 67 and exit speed: 62
Junior High - Bat speed 65 and exit speed: 61

Has anyone else heard that a rule of thumb is 1 MPH equates to about 3 feet of carry? Ex - 60 exit speed = 180ft in distance? I understand launch angels have a lot to do with distance. Just curious if others have heard a similar rule of thumb.

That estimate is reasonably close. Like you said, many factors at play including altitude, humidity, launch angle, and spin rate.
 
10u I know about 5’0” about 100# put 2 over 200’ fence in tournament play last season. It was an 11” ball. It defys logic nothing about her stands out she is same size as everyone on her team she has a decent swing but nothing overpowering it blows my mind she had to have everything perfectly lined up. So my point is focusing on bat speed can only get you so far make sure you focus on solid contact or its just a really loud out.

Sometimes looks don't tell the whole story. Coaching 10U rec I had a girl that showed up with a bat she had out grew. She was probably 4'7"ish, maybe 70lbs. Her mother asked me how to figure out what size of bat to get her, so I suggested the ole hold the bat out with one arm for 15 seconds method. She shows up to the next practice with a 33 -11. I made her show me how she did the test. She did it in front of me with each arm, steady as a rock. We just had her choke up and went with it.

The point is, she was freakishly strong for her size, but did not stand out physically from girls that couldn't pass the one arm test with a 29 -12. The girl you are talking about is probably much stronger than those that appear to be her physical equals. Regardless, it's very impressive any time a legit 10U girl is putting balls over 200' fences.

Been the “radar guy” (pocket radar) at numerous 10u/12u and jr high/high school tryouts. I would suggest that the “average” could be tough to define because of a very wide range of abilities. IME - With a 12” ball from a tee I’d say the kids in the upper 20% (A class players) have the following exit speeds:

10u: 53-57
12u/junior high:63-65
HS: 65-68

Surely there are outliers above this as I have radared several. We would gun 6 swings off a tee into a cage with about 10feet from the tee to cage and another 5 feet from cage to pocket radar and take the average of the highest 3.

FWIW Some of the highest readings Ive gotten on girls - those girls were batting cage heros that could never get it to the field. Im a numbers geek but over the years Ive learned they really don’t mean much in translation to performance on the field alot of times.

A lot of girls can KILL IT in the cages, but transform somewhat into a shrinking daisy in a live batter's box - due to the mental pressures that don't exist until the game is LIVE. In other words: their monster cage swings turn "safe", and interested more in not missing than driving the ball deep.

A team full of 5', 100# 10U girls? That's not a normal 10U team. What are they feeding those girls!!

This is why they need live pitching in practice. I’ve never seen a game where someone was pitching from half distance behind a screen.
