Trackman

Make sure you take a quick look at spin rates - those are about the only measurements that I have some familiarity with.  As for extension, that should be a common comparable so maybe there is some good data on 6-2 MLB pitchers floating around as a gauge.  Given the relative newness of Trackman outside of MLB, the next few years ought to be very interesting as folks start to look for indicators in the data.  I would not be surprised in five years kids will be sending out "video" along with a few game "data sets" when contacting colleges - "I throw upper 80's with a top quartile speed of 88 with an average spin of 3200."

There is some very basic information on the Trackman baseball website.  Some of the data is directly comparable (assuming you can find some averages out there) with something like extension being one of them.  Others are a little more nuanced like FB spin rate.  Some folks like the high spin ("rising" FB swing/miss) and others appreciate the low spin (sort of a sinking effect).  i would say there is not an "optimum" angle but a full data set might help point out variability in pitches during any given outing and maybe highlight outliers.

Thanks for your input! I really need to compare his full set of data from July vs his full set from October. Velo went from 81-84 and strikeouts from 6-10 both over 5 innings....need to look at spin and s/m % too I guess

Can you tell me whether you can download the data or whether you simply have to review online?  I think my son has a single game on Trackman from last year and I saw some of the numbers but never say anything like a full set of data for each pitch.

I don't know if you can download the data, but can see each pitch thrown during the game.  Go to your sons profile and select games from the middle of the page.   After clicking on the game just select show game and you can see every pitch from that game.

We will be doing things with TrackMan this week at the PG WWBA championship in Jupiter that has never been done before at any event outside of the Major Leagues. 

What would that be? Dying to learn more! Learned lots of things about how my son pitches! Also leaned that PG still has to have someone who recognizes types of pitches as they happen...love there is still human element involved. In my son's last outing they couldn't differentiate his changeup from fastball so they showed no change ups when he obviously had some pitches 15-18 mph slower than his fastball still shown as fastballs....not complaining at all!! Just saying it is an evolving technology for sure! 

Spin rates - its all about spin rates these days.  With decent velo, just wanna be significantly off-nominal on the spin rate.

Actually the TM unit calls the pitches.  The tagger just keeps track of the lineup.  We have noticed change ups being marked as fastballs.  Might be better having a person tag the pitch types.  So far, that is the only problem we have had with TM.

Very interesting for sure. He had one "fastball" clocked in at 68.2 when he was mostly 80-83.6. Just assumed that hat to be a human factor....had a young lady tagging that day....no sexist comment or inference! She was just fun to talk to a couple times between innings!lol

PG....his pitch slot was very tight that game.( see attached image)...might that have something to do with tripping up the unit on pitch type?

Will all fields in use be utilizing Trackman in Jupiter?

Also effective spin rate. Nathan has written a lot about this. Involving not only RPM but spin axis. Wonder if tracman will start incorporating that more too?  Exciting times we live in. And it benefits my son who has a very low spin rate and lots of sink on his two seemer so I personally am in favor lol!

All fields will use TM and now I've been told, in ways never before available anywhere, including MLB.  Should be very interesting!  Not sure, but I think  it will include video.

BTW, Daron Sutton (HOFer Don's son) who works for PG, also does stat cast for MLB.  He will be in Jupiter and is very much Into all the new technology.

I absolutely love the technology! Like I said the very next day after he threw there were video of all 10 of the third strikes of his strikeouts posted online from Ft Myers....that was really cool to see that video that quickly!!

Hi - my 2020 just pitched in Lakepoint last weekend.  I saw the pitch velocities posted on the scoreboard...is there more info available?

Go to trackman.com sign up and explore. Tons more info out there and available if your son pitched. You will have to sign up, find your son and link him to your account....pitch speeds, pitch results, spin rates, extension, angle, arm slot...lots of information!

Lefty, Here's a cool article on PV, Perceived Velocity:

http://grantland.com/the-trian...r-data-carter-capps/

This Trackman info was very interesting after Jupiter 2014, can't wait to see what comes this year. I believe they are using something similar at son's school this year for training.

Sounds like TrackMan will be free of charge for this event in Jupiter, starting  tomorrow. Read below...

I'm not sure that things like Extension and those measurements have that much meaning by themselves. it might be usefull as a Training tool for example if your stride is too short but it doesn't say much directly about Performance (albeit harder throwers tend have more Extension because they move down the Mound more explosively).

Just got around to taking a look at some live action.  Some really nice information.  It does include EXTENSION, however I believe the definition that Trackman includes in a link is incorrect - says it is distance from tip of home plate - not distance from front edge of rubber.  This measurement seems to be running low at 5.2 feet.

Love the Effective velocity as well as the zone velocity.  Don't really understand how all the measurements sync up, but imagine someone will soon put out some good findings on how all the data relates to pitching effectiveness.  Probably lots of 3D graphs showing combinations of mph, spin and some third factor they find significant.

Extension is not about stride length.  It is about arm extension.  Stride length would be something else.  

Yeah but is extension not the number of feet towards the plate from the rubber where the release point of the ball occurs? My 2019 had 10 strikeouts and his extension was over 7' on all but one strikeout pitch. If extension is not what I think it is pleasee tell me what a measurement of 7.2 means?!

Isn't Extension the distance from the rubber to the release Point? arm Extension (and Body Forward lean) would of course have some influence but most of that distance is covered with the stride, right?

Bumping this along...

Lefty, what are his spin rates? FB and CB?

Maybe I was not clear.

From the front of the rubber to the finger tip release, is extension!

Their are some with a shorter stride that have a larger extension than those with a longer stride.  Could be due to heighth or odd delivery.  That is what I meant saying it is not a stride measurement.

With TrackMan extension is one of the main things that determines effective velocity.

So it was wrong  for me to say it has nothing to do with stride, because in many cases stride length would increase extension.

Thought I was Lefty for a second. Thinking you meant 2019.

2278 FB.  1967 CB.....not a good sample for breaking stuff tho as they only showed like 6 breaking balls and no changeups which I know was wrong as they showed some fastballs in the 69-71 range and I'm sure those were changes. Plus he was getting s/m % in the 60% range on fastballs so didn't throw many breaking balls. Also, son throws spike curve and I'm not sure what spin rates on that would be like vs traditional curveball. His has a pretty sharp downward break.
