I think i've posted this or the results of this before. 2014 Jupiter spin rates and velo. My son was the 4th highest SR with highest velo. They say that portends more fly balls & swing and miss strikes.. I guess the ball stays up longer and that is probably why he got swing and miss Ks. He also throws a 4 seam so i dont know if that affects anything vs a 2 seam.

I see great possibilities here.

"Hope" for lower velo pitchers.  A low(er) cost mass-produced TrackMan that measures velo and spin rate only.  Player resumes sent to colleges with spin rates gathered at events highlighted.  More attendance and dollars for events that give dads their son's spin rates.

But remember, we can say we want as much data as we can get - on our sons - but data cuts both ways.  Trend up/trend down?  Spin rate high/spin rate low?  Or spin rate just average. 

This will soon exist, and will be better than you think. Rapsodo will be releasing a spin rate + velocity + spin direction/break unit soon. I have one and I am testing it and improving it with them. The unit costs $3000. They have agreed to let Jerry Weinstein use it in the bullpen in Wareham (Cape) this year, too. It's very promising.

You should all know Trackman and Rapsodo have serious flaws with them that must be addressed. Trackman data that comes from games almost universally needs to be cleaned and checked before it is presented. If organizations are not hiring consultants to help correct the noisy data, the data is misleading and potentially useless. I have hired Dan Brooks and Harry Pavlidis from BrooksBaseball.net (a great site if you have never been there) to help me. It has been money very well spent.

Thanks Kyle!  Just forwarded this information to our facility owner/operator. We are getting a brand new facility - just now breaking ground. Will be very similar to hitters in Racine maybe not quite as elaborate. Considering some of this technology. A $3000 unit might be a nice inexpensive dry run!

If you had access to a Trackman during bullpens, you could learn fast enough how to adjust your grip/release to raise/lower your spin rate.  Kyle needs to pony up $40k for one of these.

I have one.

To answer a few questions posed in this thread:

Yes, the faster the ball is thrown, the higher the spin. In our tests, spin rate is directly correlated with velocity BUT the coefficient seems to be static for a pitcher. In other words, spin rate is innate in some way. If you throw a 70 MPH fastball your spin rate will be proportionally the same as your 92 MPH fastball. Trevor Bauer was the first to posit this theory and after extensive data collection it seems to hold up.

That being said, hitters probably adjust to this. It is not your gross spin rate specifically but rather the difference in your spin rate vs. the league average for your size, build, etc. How hitters perceive pitches is still rather unknown, so more research needs to be done.

For spin rate on breaking balls... well, this is a very complicated subject. More is not necessarily better. Applicable/useful spin is important. Imagine a slider that spins 3000 RPM (high) but it is all gyroscopic in nature. In theory none of this spin affects the movement of the pitch (a true high spin gyroball) and the pitch "hangs." This is the mythical (0,0) pitch that PITCHf/x is calibrated to, a pitch with no magnus effect due to spin.

Dr. Alan Nathan writes the most on this subject. I suggest reading this.

The answer, like most in baseball, is that "it depends." Most theories out there on how spin rates are useful or how they should effect pitching are just that - theories. Untested, unproven. It will take many months and years of testing with a Trackman unit in a controlled setting to really uncover how it will be useful for player development, not just scouting.

And that's what I intend to do with mine, anyway.

Kyle, please open a facility in Southern California!

...and in Georgia too! LOL
