Who Owns Your Player’s Development Data?

One of my players trained at three different facilities last year. Rapsodo sessions at one place, PitchLogic at another, some Trackman work at a showcase. He played on four teams with game data (a spring and 2 fall school teams, plus a summer travel team). He’s got other health and strength metrics in various apps. By December, his development story was scattered across six different logins, five different dashboards (no combined game data dashboard), and six different formats. He has even more if we start looking at his hitting.

Sound familiar?

This is the reality for most families in travel baseball. You’re investing serious money in player development, and the data that documents that development — spin rates, velocities, movement profiles, progress over time — lives in silos you don’t control.

The Tension Nobody Talks About

Here’s the uncomfortable truth: the facilities and technology vendors who create this data have little incentive to make it portable. Their business models reward stickiness. If your data lives in their system, you keep coming back to their system.

I don’t say this to vilify anyone. These are businesses, and businesses need to survive. But it creates a tension that families bear the cost of.

Facilities have the money to invest in tracking technology and analytics platforms. Families need the portability to maintain continuity as players move between facilities, change geography, or simply want to see their full development arc in one place.

Who funds it versus who owns it — that’s the question nobody’s answering clearly.

What If We Treated Player Data Like Medical Records?

Think about how healthcare handles this. Your doctor creates your medical records. The provider generates the data, maintains the systems, employs the staff. But you, the patient, have portability rights. You can request your records. You can take them to a new provider. Your history follows you.

The provider funds the creation. The patient owns the portable artifact.

What would this look like in baseball? A facility invests in Rapsodo, employs coaches who run sessions, pays for the analytics platform. During the time a player trains there, data aggregates into something useful. But when that player moves on — to a new city, a new facility, or just a different phase of their development — they take their history with them.

The next facility can add to that history. The player never loses what they’ve accumulated.

What This Means for Facilities

Some facility operators might read this and think: why would I pay for something that helps players leave?

But consider the alternative framing: you’re not paying for lock-in. You’re paying to be the place that gave families something valuable they’ll remember.

In a market where every facility has the same Rapsodo machines and runs similar programming, the ones that differentiate will be the ones that think beyond the transaction. Families talk. The facility that treated their data as belonging to them — that’s a story worth telling.

Where This Goes

I don’t have all the answers here. The economics are genuinely hard. Tracking system vendors need revenue models that don’t depend on data captivity. Facilities need value propositions that survive player mobility. Families need something that actually works without requiring a computer science degree.

But I think the medical records model points in a useful direction. Provider creates, patient owns. Funder and owner don’t have to be the same.

The families investing in player development deserve to see the full picture of that investment — not fragments scattered across a dozen logins they’ll eventually lose access to.


I coach high school baseball in western North Carolina and think way too much about data and player development. If you’re a facility operator or technology vendor working on this problem, I’d love to hear how you’re approaching it.

ABCA 2026 Downloadable Schedule

The American Baseball Coaches Association conference will be January 8-11, 2026, at the Greater Columbus Convention Center in Columbus, Ohio.

This is my second year creating a version of the schedule you can give to your coaching staff that the can fit in their pocket to decide which sessions to attend. The subject to modification, but this is the current compiled version. This is likely most useful if you’re bouncing between session types, but it can also be useful just to keep track of your own schedule. I find something useful in each type of session. If you’re not an ABCA member and want to join, click here!

How it’s organized:

All sessions – main stage, expo stage, youth sessions, panels, FCA events, and diversity workshops – are all listed on the 4-page spreadsheet. They are sorted by start time. Sessions are not all the same length. There is a column at the right, so that you can mark down who on your staff is going to which session.

What I did:

I used ChatGPT to build the spreadsheet, with guidance and editing by me. It was much easier than last year’s cut-and-paste.

Here it is as a PDF you could print:

As a spreadsheet you can edit:

ABCA Trade Show

This year, you also get easy access to the Trade Show floorplan. I highly recommend making your list of vendors to visit — you can print a list from the floorplan — and make sure you allocate plenty of time to walk the Trade Show floor to see what’s on offer and meet old & new friends.

Vendors, there are still spots available! Reach out to Juahn Clark, ABCA Trade Show Director
at (336) 821-3143 or jclark@abca.org, pictured here with small vendor Michael Dobre who sells a great breaking ball trainer (https://dobrebreakingballtrainer.com/)

Charting Consistency in Pitch Movement

As I dive deeper into data, the one thing I become more convinced of is that consistency is the most important thing for a pitcher. If you can get your delivery to be consistent, you’re going to be able to reliable put the ball where you want to. The most important thing in pitching is throwing strikes, and consistency makes that easier.

So, Sean and I had a bullpen with one of our guys this week. I got PitchLogic data on his pitches and I pushed it into the Python visualization code I’ve been working on. Among the charts it creates is one for movement by pitch type. On that chart, it creates a box that’s where about half the pitches would be if he threw with this consistency. So, for some players and some pitch types, it can be very large and for others, very small.

For these four-seam fastballs, that box is about 4 square inches. You can see most of his pitches are near it and a third of them are in it.

If Player One can get all of his four-seam fastballs to move 15 to 17.5 inches vertically and around 8 to 9 inches horizontally, he’s going to be consistently hitting his aim point.

Our goal isn’t for all of our pitches to put their pitches in his box, but, rather, that he consistently throws his four-seams this way. If he does, he can change his aim point and dominate hitters.

Every player is going to have a different box. Here’s a younger player whose box is about 10 square inches. As he gets more consistent, there will be fewer outliers and his box will get smaller (and he’ll throw more strikes).

I’ve only recently come up with this box – so recent that I don’t even have a name for it. It’s from the inter-quartile range of the movement data, so I could call it the IQR box, but that would get everyone asking why it’s called that instead of what it means and how it’s used. Maybe I could call it the MCB – Movement Consistency Box?

The PitchLogic ball auto-tags the pitches by type. I love this because it points out when players are not doing what they intend (throwing a cutter when they want to throw a fastball) or when they are mislabeling their pitches (throwing a cutter but calling it a fastball). The unintended variety tend to be younger players, while the mislabeling tends to come from high school players.

For our bullpen the other night, four pitches go auto-tagged as cutters. All four would have been down and to the left of the MCB for his four-seam fastballs. So, these wouldn’t have gone where he thought they would go. He also lost velocity on each of them. So, that high, hard inside pitch ends up slightly slower and out over the plate. Yikes!

Is it due to incorrect grip? Or a bad release? Is it lack of pronation? I honestly don’t know, but I know it’s something we’ll investigate and work on. I also need to check location on these pitches – time to get back to the code!


I’m not including any of the visualization posts in the Coaching Courses because they don’t really fit. They’re a bit esoteric and not really what you need to start coaching. It’s fascinating stuff, though.

Visualizing Pitching Data

I’ve been dumping my PitchLogic data into spreadsheets and manipulating it in HCL Notes databases, but I wanted to see some ‘visualizations’ to evaluate the data a little better. A picture is worth a thousand words, right? Or it “a pitcher is worth a thousand words”?

Within the PitchLogic app, you can get the vertical and horizontal movement for a single session. When you go look at your session reports, you see a little more. So, I’d used ChatGPT to help me create some visualizations from my downloaded data. Here’s a sample, showing those movement profiles by pitch type. This is only from about 50 pitches, so it looks interesting, but is a little less-than-actionable.

As you know from Coaching 203: Bullpen Pitch-Tracking Sheet, I’m collecting location data on my bullpen tracking sheets, so I decided to create some charts and graphs using that.

Now, that gives a very good visual impression of where the pitches are going. Fortunately for us, this is our hardest throwing pitcher and we’re going to have him for two more years. One of the things that pops out about this is that he’s missing high (1-2-3) more than he’s missing low (7-8-9) with 34% of his pitches being high and just 6% being low. Oddly, in this sample, nothing inside or outside at strike zone height. That could be just because it’s a small sample or might point out bad data collection (we might be categorizing those inside and outside pitches as high or low as well.)

The good thing is that I can also break this down into different pies for each pitch type, but the lack of data doesn’t make that real useful right now. When you have it, it can really bring home what the quality of the pitches really is.

I learned something new as well. I might have seen a boxplot a few times, but I never understood them. This uses statistical methods to place the velocity of the various pitches he’s thrown. Now, you must keep in mind that these are to auto-tagged pitch types. For any of you who are coaching young teens, you’re going to notice that how the PitchLogic ball tags the pitches is not always what the player intended to throw.

I’ve been telling other coaches that one of the things we need to work on with youth players is “grip discipline”. Most of them grow up with no instruction in how to grip the ball at all. Sometimes, they get instruction in how their fingers ought to be aligned, but rarely do they get instruction in how to line up the laces and their fingers the same every time. When I first started coaching Little League, I sent a Dad out to the mound to talk to our pitcher. He came back and said, “He was holding the ball with three fingers!” That was when I first realized that a lot of Dads and assistant coaches also need coaching and instruction.

Technology, and the PitchLogic ball in particular, give us a lot of numbers. As any old baseball guy will tell you, the only number that actually matters is balls and strikes. I don’t focus on how to improve those myriad numbers, like a player’s spin rate or velocity. The goal is consistency since moving the ball in a consistent way makes it easier to throw strikes. So, we look at how consistent is the arm slot, or whether the release makes it a cutter instead of a fastball. Then, we use the numbers as a gauge for ‘how consistent’ the pitches are.

How can you do this?

If you have a PitchLogic ball, you can get your data. Just go to the “hamburger” down in the lower left in portrait mode or upper right in landscape mode and then click on “Get CSV Data”. This will let you pick the dates for which you want data and then email you a file. You can drop it into ChatGPT and start asking it to make you some visualizations.

I plan on writing about the technical details on my software development blog, so for those who love that stuff, revisit here in a few days for a link!

Revisiting Vendors from Prior Years at ABCA 2025

Not only are there new vendors with new products, but also vendors we’ve met before that have created new products or modified existing ones with the experience they’ve gained.

Krato Sports

20250103_1054557152184359762417330

Back in 2022, we visited with Justin Kuhn and Rick Weaver to learn about their innovative bat weights. They screw onto any part of your bat and, like the RITEND weight we first saw yesterday, can be used in batting practice as well as dry swings. These have been upgraded, with plastic coverings and longer bolts to avoid breakage. They’ve also created some new products to save coaches money and provide more opportunities to improve our players.

20250103_1054267383939342699316398

They’ve got Tee Toppers (and tees), plyo balls (with or without “laces”) and nets to hit or throw into. Since it’s a few guys who coach together, they collaborate and they know that coaches/programs don’t have any money to waste. Check them out at Booth #105.

The Nexus Mount

I was very excited to see the latest products under development at The Nexus Mount, who we met last year.

Brandon Miller has an iPad mount in prototype (rumored to be used in MLB spring training) that I’ve been hoping for since I needed to get an iPad to maximize my PitchLogic data review. It looks really good to me, with all the design elements of the OG Mount, only big enough for an iPad. It is due for pre-orders in February or March, so you might have it during school seasons and certainly will be seeing it during summer ball.

There’s a new swivel ball mount they’re coming out with, since some cameras need that when used in the mount to keep the view level. I didn’t get a photo of this, but it is really cool.

20250103_1132254873445881770960057

Also available for pre-order soon is a stand for your mount, for when you’re not allowed to have it hanging from the screen or maybe even not touching the screen. You can have the stand on the wall of the backstop, which is way easier that doing that via tripod (which was part of the reason to use the Mount in the first place!) I know I’ll be getting one of these after my pre-order in February or March.

Less than 24 hours til the Trade Show Closes!

They’re on a break until 4pm, with the Coaches’ Social running until 6:30pm tonight, but you have to see and purchase your products either tonight or tomorrow. Otherwise, you won’t have this opportunity until we get to Columbus for ABCA 2026.

Meeting New Vendors at ABCA 2025

Every year, I hunt around the Trade Show floor trying to find innovative products and interesting vendors. I want something useful, and a story to go with it. This year is no different!

RITEND Bat Weight

Almost hidden in the corner of the Trade Show Floor is RITEND Bat Weight, staffed by new President, Jakob Lindemann, son of the founder, Skip Lindemann. Skip always stressed getting your hands through the ball when coaching his son and his teams. So, he developed a bat weight for the right end of the bat – the RITEND bat weight is down on the knob. Jakob’s recent engineering change to the weight was to go from aluminum to steel, allowing a more compact weight. It’s easy-on, easy-off and is worth a look to see if it’s the tool for you. See them in Booth #152, in the corner.

Dobre Breaking Ball Trainer

20250103_1343301553623602344846560

Back in Asheville, at Bob Lewis Ballpark, I ran into Michael Dobre, who was showing and selling his Breaking Ball Trainer. One of the things that sparked my interest was that Mike is a veteran. He was an Army Ranger (airborne-qualified, too) who was in the 2017 Best Ranger Competition (one of 53 teams of truly qualified soldiers). His trainers are baseballs with a ridge on them to allow players to learn the grips and how to throw the pitch with the best movement. He’s in Booth #118

20250103_1101201542383234793589012

I spent some extra time, talking to his Dad, who served in the Marines. I always carry my coin for Jordan Haerter, so I shared with him the story of Haerter and Yale in Ramadi – the “Six Seconds” speech that General Kelly gave. It was great to be able to share that story and talk about developing youth both through Scouting (I was a Scoutmaster before I was a baseball coach) and through baseball.

While I was there, Juahn Clark, who is the ABCA Trade Show Director, happened by to share how much his daughter enjoys using the trainers that Mike developed for softball. Designing his softball trainers involved a lot of research and Juahn testified that they both work AND are liked. He noted that a good tool that players don’t like might as well not exist.

Trade Show Coaches Social

Don’t forget, the Trade Show floor will shut down for an hour to give them a break before reopening for the Social Hour at 4:00pm. Your drink tickets are attached to your badge!

ABCA 2025 First Day

As the coach of Randolph-Henry baseball (VA), Josh Barmoy, said, “Off to Disney World for baseball coaches” when tweeting about his ride in. It truly is Disney for us.

Registration was a breeze once I figured out where it was (top floor of the atrium) and then I hit the Trade Show. As I’ve noted in prior years, like with ABCA 2022 First Day, there is a LOT to see. I’m committed to visiting as many vendors as I can and sharing their stories, especially the small ones!

But first, a story

In my final season coaching Little League baseball here in Alexandria before we moved to Asheville, I got a new player, who had never played baseball before. Our Young E. was a relatively good-sized kid, but there were probably no sports in his background. His arms were obviously strong and I knew there was potential.

When we brought out the PocketRadar to find out how hard everyone threw, Young E. couldn’t throw hard. He sometimes threw one that registered 25 mph or so, but it was in a random direction. Sometimes, in practices leading up to the season, he would get distraught with bad directional control and think he wasn’t throwing any harder.

By the beginning of the season, using both PitchLogic and PocketRadar to track his progress and provide encouragement, he was able to throw it 30 mph. By the end of the season, he clocked one at 41.8 mph and it was in the direction of his teammate and catchable.

Three years later, he’s getting ready for another baseball season. We showed him that the OUTPUT of his efforts was improving so that by the end of the season, his OUTCOMES were far better.

Why bring this up?

This afternoon, the CEO/Co-Founder of PocketRadar, Steve Goody was on the Expo stage talking on a panel about Integrating Evaluation Technology in youth baseball. On the stage with him, Neil Anderson from SkillShark Athlete Evaluations was explaining how his software helps organizations evaluate players using PocketRadar and eliminate all the paper-to-PC tracking of evaluations. Then, Alex Sumner of Fargo Youth Baseball and Jordan Draeger of GoingYard Baseball talked about how easy it is, how it provides objective feedback to players and helps shape player development.

Both PocketRadar and Skillshark are doing their share to “democratize the data.” By making data transparent to the players and parents, they encourage the players, show them their progress and give them guidance on how to get better. As with our own Young E, retention is much improved.

Great Conference, Like Always!

I’ve got my list of vendors and I’m stopping in to see a broad variety of them to hear what everyone has to say. I’m an Outgoing Introvert, so I use my outgoing times to meet as many as possible, especially the little ones or the folks who have no customers in front of them at the time. Then, I use my introvert times to share my experiences with all y’all. (Since I live in North Carolina now, “all y’all” isn’t awkward to my companions.) I do have some revisits planned (I spoke to Brandon and Morgan at Nexus Mount, so will have an update to share!)

ABCA 2025 Downloadable Schedule

Last year, I handed out spreadsheets with the schedule to our coaching staff in attendance. Since the schedule has already been released, but subject to modification, I thought I’d share the current compiled version. This is likely most useful if you’re bouncing between session types, but it can also be useful just to keep track of your own schedule. The three of us are in travel ball, so we find something useful in each type of session. If you’re not a member and want to join, click here!

How it’s organized:

All sessions – main stage, expo stage, youth sessions, panels, and diversity workshops – are all listed on the 3-page spreadsheet. They are sorted by start time. Sessions are not all the same length. There are a few columns at the right, so that you can mark down who on your staff is going to which session.

What I did:

I used simple copy-and-paste into a text file from the ABCA pages. Then, I moved the data around so that it’s in columns instead of boxes. That made sorting simple.

Here it is as a PDF you could print:

Coaching 310: Throwing On-ramp program

Here in Asheville, we have lost some time that we had intended to use as an on-ramp to velocity improvement. The hurricane devastated many towns and neighborhoods in our region, but we expect to be back underway in the next few months. Many of the local fields have been badly damaged, so we will likely have to improvise and travel more than we would normally.

As such, we plan on offering an on-ramp program to local high school players to get them ready for their tryouts and spring seasons. The greatest hazard to a young arm when looking at high school teams is that you’re trying to impress the coach on Day 1. Without a proper on-ramp, you could quite easily start the season with an injury. The best preventative method is to on-ramp yourself in the 4 weeks prior to those tryouts. For this, we turn to the Driveline Skills that Scale: The Complete Youth Baseball Training Manual.

We’re a twice-a-week team practice group, usually doing our practices on Mondays and Thursdays. This fits well with our plans for an On-Ramp, Powered by Driveline. The first practice date for NCHSA in 2025 is Wednesday, February 12th. So, we need to walk back four weeks, finishing on Monday, February 10th. Thus, we start on January 16th. That fits well with the ABCA Convention on January 2nd to 5th in Washington, DC.

Equipment

For the on-ramp, each player ought to have their own set of equipment or share it with a partner. This way, they can bring it to both team practices and do two other practices with that partner each week.

1 pair of 2.5kg wrist weights

1 set of plyo balls (Driveline youth set): Green 1000g, Blue 450g, Red 225g, Yellow 150g, Gray 100g

1 Jaeger bands

Workout Types

Recovery: This is our most common workout, used to get us started and repeated in between team workouts. It’s about 50 throws and should never exceed 50% intensity.

You can download a PDF of the plyo drills or watch the videos.

  • Warm Up
    • J-Bands: 10 of each of the 8 exercises (download PDF here)
      • Forward & Reverse Flys
      • Elevated Internal and External Rotations
      • Tricep Extensions with Pronation
      • Bicep Curls with Supination
    • Wrist weights: 10 of each of the 4 exercises (PDF here)
      • Pronation Swings (Spill the Cup)
      • Two Arm Throws
      • Cuban/Gorilla Press
      • Pivot Pickoff
  • Training
    • Plyo Reverse Throws: 10 each with Blue (450g) and Green (1000g)
    • Plyo Pivot Picks: 10 each with Blue (450g) and Red (225g)
    • Catch play: 30 throws with baseball, not to exceed 50% intensity

Hybrid B: In our on-ramp, this is actually the most common team workout. It’s basically double the workload of the Recovery workouts, with a bit more intensity — 70%. This is used to slowly ramp our arms up to the intensity we’re going to need for regular practices, bullpens and games. Driveline labels it “Hybrid B”, so we’ll stick with that, even though it is the most common workout in all Driveline youth throwing programs. Somewhere between 90 and 120 throws, up to 70% intensity

  • Warm Up
    • J-Bands: 10 of each of the 8 exercises
    • Wrist weights: 10 of each of the 4 exercises
  • Training
    • Plyo Reverse Throws: 10 each with Blue (450g) and Green (1000g)
    • Plyo Pivot Picks: 10 each with Blue (450g) and Red (225g)
    • Plyo Roll Ins: 10 each with Red (225g)
    • Plyo Step Backs: 2 each with Red (225g), Yellow (150g), and Grey (100g)
    • Plyo Walking Windups: 2 each with Red (225g), Yellow (150g), and Grey (100g)
    • Long toss: 40-70 throws with baseball, building to 70% intensity (check Long toss distances, keeping that 70% in mind)

Hybrid A: This is the most intense workout of the On Ramp, so we just do it once, near the conclusion of the cycle. Total throws are still 90 to 120, but our intensity can go up to 90%.

Get Training!

I’m very much looking forward to running this program in the new year and I’m sharing in hopes that others use it for their programs as well. Note that this program is the Driveline 13-14u program. The 9-12u program is a little less intense – 3 days instead of 4 (No Wednesdays) and no Green (1000g) plyo reverse throws. I heartily encourage everyone to purchase a copy of the Driveline Skills that Scale: The Complete Youth Baseball Training Manual. There’s loads more content like this as well as mentoring on how to coach, how to plan, and how to develop your players.

Coaching 302: Arm Slot and Spin Direction

This is the start of a multi-post series on how to use a PitchLogic ball to coach youth pitchers.

How do I use the ball?

You’ve just put down a few hundred dollars to get the latest pitching technology. Your ball came in the mail and you’ve charged it up. Now what? Get familiar with using it yourself. Check the player app video to get the basics.

Once you understand how to pitch the ball and see the data, you can bring it to a practice. Pick a few pitchers to throw your first bullpens with the PitchLogic ball. Make sure that you schedule a minute per pitch – so if you want to have 6 pitchers throw 10 pitches, you need to have an HOUR after they’ve warmed up. That includes getting them ready, some time discussing how to use the PitchLogic ball, showing them some of the data and letting them know what they did well or need to work on. I always think I can get 2 pitches per minute, but it never happens that fast.

Arm Slot and Spin Direction

This is where you start using the tech to coach your pitchers. Trained eyes will pick up the arm slot and spin direction on every pitch, as well as be able to tell you when they vary. Trained eyes are rare in youth baseball, but by using the PitchLogic ball, you get the equivalent of those trained eyes on every pitch. For trained eyes, it also lets you quantify those values and track them over time.

Your first tendency is going to be to change the arm slot to what someone told you it should be. Unless the player struggles to throw at all, you should concentrate on getting them to be consistent with whatever arm slot they use. If the spin direction varies, work on their grip to get it to be more consistent. I’ve usually urged them to have arm slot and spin direction match up, as that is the most efficient. I even have a computed column on my spreadsheets that shows me the difference between the two. Nonetheless, consistency is how they learn to throw strikes.

When you start looking at that arm slot and spin direction, you should share it with the player. Often, the grip is the source of the difference in the two. I’ve coached a number of players who throw with a cutter grip, with their fingers not quite on top of the ball, with the ball sliding out that gap between finger and thumb. A cutter moves similarly to the fastball they’re emulating (2-seam or 4-seam) but not as much. If the player is already throwing that for strikes, you might want to keep that grip while trying to create a fastball grip. That would give them two pitches that are very similar but different enough to confuse hitters.

You might notice that we haven’t mentioned anything about pitch type yet. That’s because the arm slot should be the same for every pitch. What you do with the grip and your wrist is what makes all the difference.
