Was curious to see how many people here ever set up the gun for exit velocity readings? If you do, how does it compare with tee velos and the like. Thanks for your time.

My grandson took part in an NCTB Showcase this past weekend and posted 95mph Exit Velocity during BP. After his 1st swing they started videoing him and Tweeted the video. He is only 15 and we were told this velocity was near the best in the nation for Sophomores.

Something I found: So I Measured my Exit Velocity, NOW WHAT? (Average exit velocity by age) Now that you know your exit velocity, you can see where you sit among your peers. Here’s the breakdown of what is considered an exceptional exit velocity among each age group: Ages 8-10: 55-65 mph Ages 11-13: 60-70 mph Ages 14-15: 75-80 mph Ages 15-16 (High School JV): 80 mph aluminum/ 75 mph wood Age 16-18 (High School Varsity): 90 mph aluminum/ 85 mph wood Collegiate: 95 mph aluminum/ 90 mph wood...

Interesting, but this doesn't paint the whole picture. First, who is categorizing these exit velos with the level of play, because there are quite a few guys in the MLB currently who, by this chart, would be somewhere between JV and Varsity ball players. Just saying, this needs context. Is this average exit velo or maximum exit velo? For many batters, the difference between average and maximum is 20-25 MPH, sometime more. That is a pretty sizeable difference, and no disrespect to anyone on...

Average exit velo on statcast for an MLB player has a much wider range because it's being taken in game against elite pitching. In my experience recording exit velos off a tee, the range is usually 3-5 mph from their max out. Someone who tops at 95 off the tee is sitting in the 89-93 range, 75 mph would be a pop up to the pitcher. The OP asks about bp. It's been studied that 1 mph of pitch velocity equates to .20 added exit velo. So bp exit velos should be about 6 mph harder. From evaluating...

So, instead of using the available data from statcast, which is pretty much the gold standard, we should speculate? My point is this: sure, all of these players are capable of generating exit velos off a tee in an artificial setting with no real variables. But a pitched baseball is the biggest variable of them all, and the average exit velo for these players tells me that it really doesn’t matter what is measured off the tee, because on average you aren’t going to produce that during a game.

The stat cast average ev is irrelevant because peaches grandson isn't facing 90mph sliders. 15u pitching has far less variables, and thus the average exit velo will be much closer to max. No matter what stat cast measurement your sort by, there is almost no correlation with top players. Guys who hit 35 home runs have ev 10 points lower than AAAA players. You might not have read my post; I refer to stat cast data several times. I simply deduced ev off a tee by subtracting the help of the...

My point is it doesn't matter how you measure exit velocity, and it doesn't matter whether the players are MLB. You are choosing to ignore the trend based on the level the trend is measured at. I think the trend is probably true at any level. The facts are that the players are facing typically similarly talented competition. 15U players face 15U pitching, MLB caliber players face MLB caliber pitching. 15U hitters have 15U experience and strength...MLB players have...well..you know. Sso to...

PG PBR and any college camp all measure it. The pools of talent MLB scouts look at have already been weeded out from those with weak measurables. Figuring out ev from a tee is useful as a comparison tool, and a progression stat. Gained 5 ev in a year? Studies say you can hit the ball 25 feet further, and those grounders in the hole might get through. Good luck finding me a player at a P5 with below an 88 ev from a tee.

average or maximum? In game or off a tee? This is why scouts and coaches watch players play in games before offering or signing them.

I am sure as the tech becomes more affordable and easily deployable, we will see it part of the recruitment game like the radar gun

Due to the speed of the incoming pitch, exit velocity should be slightly higher. Not sure what it would really tell you though. Off a tee it gives you a baseline/metric for improvement.

Does anyone know of a resource that provides info about catcher pop time and throwing velo FROM SQUAT by age? I see charts floating around with throwing velo, but obviously a catcher coming out of a squat shouldn't compare their throwing velo against a pitcher or outfielder who has the luxury of a completing the full, long throwing motion.

@playhard314 The C velo you see in in PG stats is from the crouch. Also, it doesn’t necessarily correlate with the pop time listed. They will take the best velo, often regardless of whether the ball ends up in the glove or somewhere in center field. As for timing, Coach’s Eye is the app we use. Import the video into the app, then you can timestamp glove to glove. Also helps with transfer time. I’ve attached an example from a game. Recorded on GoPro, imported to phone, add time stamp.

Yup, that’s Sennason. And thanks for the kind words. BTW, his is probably a good example of focusing on technique, ignoring the raw numbers at showcases, and letting the body catch up as his matures. He’s never been gunned accurately higher than 73 from the crouch in showcases. And he’s never had a pop at a showcases lower than 2. But in game, he’s regularly under 2 and gets guys out. We hope that ultimately that will be what matters.

I don’t know how old your son is but I would argue for keeping it as fun for as long as possible. Focus on good technique to prevent injuries, playing multiple positions and playing multiple sports. That will keep him athletic, valuable to his teams, and eager to get back to baseball ( if that is his love!). I was just looking at a Fall 15U picture of my son’s team and so much has changed with those kids even in the past 2 and half years in terms of growth, development and trajectory.

I wouldn't worry about it until he's on the big field and well into puberty with man-muscles. Every kid is different.

Thanks for the video! Is the catcher your son? He looks great!

Can’t cheat the start on electronic times.

I am not aware of a chart that summarizes what you are looking for, but there's a lot of data out there. PG ranks players of every age and position and they publish results of the top performers at their showcases. You may have to pay money to get access to this, I can't recall. It's been a couple years since I looked this up, but they have velo and other stats by position. You can look at pop times and velo for catchers within each age group. The data is just data, and there are problems...

Yes, they measure velo for catchers coming out of the squat on a throw down to 2nd base, with the caveat stated above that they've got a bit of a running start (i.e., not representative of what a catcher can really do in game action). I used my iPhone to capture the video and then imported it into Coaches Eye, which is a free app that applies timestamps to each frame. The resolution at 60 frames per second is 0.016, so plenty accurate for this use case. You didn't say how old your son is,...

How are you cheating the start with electronic timing?

@Smitty28 wrote, “ it’s gotten so bad that kids are literally stepping across home plate as they catch the ball and have a running start. Look at the videos and you’ll see what I mean. So how do you use this data to evaluate and make a meaningful comparison? I don’t think you can.” Bingo! Same is true for EV readings that are generated from Happy Gilmore swings, and 60 times that are artificially low due to kids jumping the start. None of this is speculation. I see it at every showcase - and...

Do you know if they measure general throwing velo? Or do they actually measure velo for catchers coming out of a squat on a throw to 2nd base? And thank you so much for your reply. It definitely seems like you've had some experience in this area. I can definitely see what you mean about maturing at different ages (I would love to find some stories to better illustrate this point) Question - When you say "Use video with timestamp so you can break things down, not stop watch" what tool do you...

We were at a showcase in June and the timer told the dad what the kid’s time was and asked the dad if it was accurate! The dad said he’s usually .2 faster so that’s what they recorded. At that moment I stopped paying attention to showcase numbers. We were at another last weekend and a kid was doing the old jump out and throw pop. My son was .1 slower than him but I heard a coach say my son’s was more like a live game pop. One of the biggest areas my son has improved is getting the back foot...

You just made a perfect argument for why you should wait until age 17 to commit.

What age would you say is a good time to start paying more attention to your "measurables"? Going into high school? Or maybe when starting to think about college?
