2019 just pitched at Ft Myers a week or so ago, and had his second game recorded this year on trackman. I LOVE THIS TECHNOLOGY! Am learning lots of stuff about his stuff on the hill. This outing has video posted of all 10 of his 3rd strike pitches from his strikeouts and also shows his extension and angle for each of those pitches.  He is 6'2" and his extension is 7'1-7'2".....what should it be? Also is there a place we can see the extension for all his pitches? Most of his angles are from 11:15 to 11:45 on fastballs...what does this tell me? Any insight is great....also learned for his 5 inning 61 pitch outing velo was in a tight range of 80-84 whereas his previous PG high was 81, so moving on up for a 15 year old!

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.

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.

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.

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.  

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...

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.

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

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.
