Exit speeds

74 off a tee? 90% of all men and college women can't hit that hard. That's a strong 12 year old. A 74mph softball should carry about 270ft

You can typically add 10%-15% of the pitched speed to exit speed depending on how the ball was hit

Like I said, I walked away not sure about all the exit velocity stuff. It was off a tee and with a pocket radar and I was looking at it with the other coach.

Coach Lisle touches on it in this podcast- from memory they came up a ball hit at 26 degrees with an exit velocity of 68? Mph would be otf at S.C. and most other college parks.

You can easily measure angles with an iPhone and the measure app. I’m sure android has a similar app. I have marked all of my nets with approximate line drive launch angles and in my home cage I ran a red string across the top to mark what is “not a pop up” for a well struck ball. It was surprising to dd how steep she could hit a ball after years of having a goal of “hit the back of the cage” as a goal.

SC worked quite a bit on this under Lisle. Seem to recall Jake telling me about an 80mph club. Was all about hitting bombs, and it seemed to work. That said I do not think he will be missed at SC.

Went back and looked DD at 11 years old hit at a facility with the tossing it at 19 mph. Her exit speed was 61. When we hit off the tee it was a couple of months later with a pocket radar. we had used the pocket radar a few times and she was around 60 on her best swings. That day she hit one ball 64. Maybe something was wrong with the pocket radar that day.

I can tell you the numbers do not line up with the hitters with the most pop as far as I'm concerned.

I think these tools are great at measuring and comparing in controlled environments, but performance off a tee in practice is very different that playing live. We've all seen players loosey goosey in practice and then "squeeze the bat to sawdust" during a game.

It's all physics and no magic. Set up a pitching machine and find out what speed, spin, and angle it takes for a ball to go over the fence. It's very simple

a lot more variables vs a live pitch.

A kid can kill the ball off the tee,
and still mis-time, mis-hit... chase balls out of the zone, make contact without squaring the ball, etc. vs a live pitch

When it comes to the free Blast Vision app, that gives hitters info after contact. So exit velo, launch angle, estimated distance. The Blast Softball app (still free, but can choose to purchase other options) is what hitters use with the knob sensor, and gives info on what is happening before contact. Things like hand speed, attack angle, and connection. All good info, but like others have said, it has to transfer to the game.

To answer Coach James' initial question...how much emphasis do I put on it? I guess I would answer that by saying "some". It's not that I'm daily talking about exit velo and attack angle, but we do have stations occasionally where their metrics are measured and we chat about it. It lets me know if they are improving and if what we're teaching is actually working.

I also like that the Blast Sensor is approved for game use. I can have a kid put it on their bat, open the app, and compare those swings to the ones in practice. I don't have those conversations during the game, obviously I want their minds clear at that time. But the next day, we can have a conversation about "so this is what you're doing in practice, vs what is happening in games."

RB - been curious about that. Specifically wondered if he had been applying his philosophy of staying back in the box to everyone and how what was received by them?

Using pocket radar for exit speed, exit speed will be off. Blast, hittrax, and whatever On Deck uses is much more accurate.

74 off of a tee is much more common than you think.

Exit speeds can be much higher off a tee. You can load up and swing from your rear.

Big power hitters in woman's slowpitch can hit the ball 300 feet. A 300 ft shot is extremely rare in fastball.
