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.
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.
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!
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
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.
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.
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.
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.
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!)
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.
As I continue my evolution as a coach, my use of my tools, especially the PitchLogic ball, in bullpens has gotten more refined and the quality of the training and the information gained has increased dramatically.
Several weeks ago, PitchLogic hosted a webinar for ABCA, “What Pitching Data Really Means & How to Use It at the High School, College and Professional Levels“. It was a terrific webinar that delved into the experiences of pitching coaches at all levels. Truly enlightening, but not as focused on using the technology as I’d hoped. So, as a step toward improving our own bullpens, I’ve decided to share out how we’re doing it. I suspect this will provoke feedback and allow an iterative process to improve this for everyone.
Our environment
I’ve implemented the use of technology in our practices and in in-game bullpens over the course of the last 4 years. The pitchers involved are probably significantly younger than most PitchLogic users, ranging from 10-year-olds up to 15-year-olds. Since I started in Virginia and moved to North Carolina, no individual player has been in the system for more than 2 years. In 2024, it will be the first time that more than 3 of the pitchers involved has been tracked for more than a year. In every case, I’ve been the only person with regular access to the data (and the only one who understood it for most of that time!) For most of the time, I was the head coach. The past six months, I’ve been just a pitching coach and more focused on the process and data. I’ve also started sharing the spreadsheets with one of the players who envisions a career in engineering, since it’s good to have another set of technical eyes on the data.
The tools
For our bullpen tracking, we’re utilizing the Smart Coach Pocket Radar, F5 Sports’ PitchLogic ball, my own bullpen tracking sheets, Microsoft Excel, iCloud Notes, and the apps for PitchLogic and Pocket Radar.
The SmartCoach Pocket Radar was the first piece of technology that I acquired to help me coach my pitchers. While some of the old men that I play with contend that it’s not accurate (they think they throw 75mph while in their 60s), it shows readings matching the stadium signs when we use it at minor league ballparks. It doesn’t read speeds below 25mph, but unless you’re coaching 9u, that won’t be a problem. The best use of this is in-game to track velocity. We use it in bullpens for immediate feedback on the pitches. This is the velocity that we record on the bullpen tracking sheets.
The PitchLogic ball provides the detailed feedback on your pitches, to the extent that it provides far more information than you can use at first. I’m up to using 9 of the 23 columns of data returned after using it for 4 years. At first, we only used velocity, spin direction and arm slot. Then, we added more as we understood the use of each and saw patterns in them.
During the bullpens, we use my own bullpen tracking sheets. Each has room for 20 pitches, which is our standard bullpen. (MLBs PitchSmart guidelines have 20 pitches in a game as the max for pitching the next day, without rest.) For every pitch, we record pitch type, velocity, and location. The pitch location gets marked with an X and for pitches with movement, we draw a line indicating how it moved. There is a spot for any notes on a pitch. At the end of a bullpen session, we take a photo of the bullpen tracking sheet for our records and hand the paper copy to the player.
The data that gets collected by the PitchLogic ball can be downloaded as a CSV file (comma separated variable) and opened in Excel. Over the course of a season, I dump all the data for my pitchers into a spreadsheet and then create tabs for every player. Each of the columns that I use has formulas in it for highlighting good and bad results. By reviewing player data over time, it’s easier to see their improvement and find areas that need more work.
After the bullpen, we upload the photo of the bullpen tracking sheet to the player’s Note on iCloud. This way, all bullpen tracking sheets are in the same place, easily accessible and comparable. Any notes on the bullpen get added, then game stats, commentary or notes on usage get added to the same note. This single location for data collection and commentary ensures that guidance, practice results and game results can be understood.
Coach ‘Em All
Since we’re coaching 13u and it was fall, everyone threw some bullpens, and several players caught them. We discovered a couple of pitchers we didn’t realize we had – one of whom threw a 4-inning, one-run “complete” game win. As a Little League coach, I started every season believing that had 12 pitchers on the roster and you had to prove me wrong. I also started every season with a one or two catchers and finished with four or five, since everyone had to catch some bullpens and some ended up liking it a lot.
By allowing everyone to throw bullpens, you can discover those unknown pitchers and work on the arms of your fielders directly, rather than as part of a broader drill. When you’re coaching kids, you can’t know their potential. You can guess, but you’re likely to be wrong. The USA 12u National generally only contains 1 or 2 kids who make the National team in high school. Early growth and early success do not necessarily lead to continued interest or success. The move from the 60’ diamond to the 90’ diamond ends the youth baseball careers of many young all stars.
Setting up for the Bullpens
Depending on the facility, we might have a full bullpen with two mounds and two plates, or we might have an open space at the field that we have to lay out ourselves. It’s good to have a hard pitching rubber and a throw down plate and your measuring tape (or pre-cut string) handy when you don’t know what you’ll get.
Probably the most important thing to keep in mind is what happens when the catcher can’t stop the ball. I’ve lost a PitchLogic ball in the underbrush and had players chase another down a hill. If you can have a backstop, net or 60′ of open ground behind the catcher, that’s good.
Initializing the PitchLogic Ball
Before the bullpen, connect your PitchLogic ball to whatever mobile device you prefer. We generally get the best connection and display of data on an iPad. Once connected, you need to select the pitcher in the PitchLogic app so that their data is stored properly and, if they have the app, shared with the player. Lary Sorensen of F5 Sports gives a good intro to using the roster.
Remember, for any throw to be recorded, the PitchLogic ball needs to be held stationary for a half second. This reminds players to “make sure you don’t balk”.
Sometimes, we have the camera on for the bullpen and sometimes not. Usually when we do, it’s on the arm side behind the player facing home plate. This allows visual feedback of the movement and location. Sometimes, we have used arm side, 3 quarters in front to provide a different view of the pitch mechanics. When video is used, it’s best to have the iPad or phone on a tripod to keep the video consistent and to allow everyone to focus on the pitcher.
Setting up the Pocket Radar
For bullpens, I usually do not launch the PocketRadar app to record the velocity of pitches or to do the video. Sometimes, there seems to be interference on Bluetooth when I try using both the PitchLogic ball and the PocketRadar. So, I either hold it in my hand, connect it to the fence or have it on a tripod, always behind the pitcher. When there are no problems hooking both devices up with Bluetooth, I’ll put it on a fence using a Nexus Mount – either behind the pitcher or behind the catcher.
The most critical accessory you can get for your PocketRadar is a Power Bank. Relying on the batteries in the PocketRadar itself is a recipe for disaster. When using the app or just running continuously, the batteries die quickly. Better to have the power bank or plug it directly into an outlet at the field. (Often, you can plug in behind home plate, but I’ve never run across at outlet at the bullpens where we’ve practiced or played.)
If you can use the app, it allows you to tag which player is throwing the bullpen. When I use the app with video during a game, I will usually tag the pitches after the game, removing throws from the catchers and hits. Since you can set the threshold for minimum velocity on recording, you can usually prevent the app from recording catchers’ throws. This season, we’re going to start using it with GameChanger when streaming the games.
I wish that I had an application that would create pitch video season collections online for each of my pitchers so that we could easily review that online. If I had employees or interns, they might be able to manually execute that.
Timing
After players do their individual warmups (bands/weights/plyos), they will do their “every days”, throwing and fielding. This is typically followed by a team warm up, with team captains running the show. Coaches don’t necessarily intervene until 20 minutes into the practice. This allows us to validate the rest of our practice plan and finalize assignments, including the order of bullpens.
Each bullpen consists of 20 pitches and takes about 10 minutes of elapsed time. This includes the player throwing to loosen up a little, resetting all the technology and paperwork, some conference time after 15 pitches and assessment at the end. I keep thinking it can be two throws a minute, but there’s a lot of process around it.
Additional prep
Sometimes, we have a few players allocated to the bullpen session before they toe the rubber there. There are a number of additional tools that they might employ and tasks they might perform to help run a bullpen session.
The easiest tool for us to use is the CleanFuego. Our youth players of any age never have any trouble figuring out how to use the CleanFuego. When I pull it out in a group of old men playing baseball, they spend a lot of thought on how to throw it. It’s honestly as easy as the kids make it. When you throw a pitch with no gyro spin, the ball flies smoothly. When your spin direction is not right, it wobbles. Sometimes, it wobbles crazily. Kids adapt to it in 2 or 3 throws. It’s been great for getting them to impart backspin on their fastballs. So, when we have a couple of extra pitchers getting warm before their bullpen, we break out the CleanFuego.
We expect to start using our Core Velocity Belt this year and I think we will be integrating it into bullpens for warm ups at the start. Having just one Belt, we’ll start cautiously and expand it’s use as we get more comfortable with it.
We also occasionally have players do the tracking. This has ranged from having them just monitor and report on velocity to having them fill out the tracking sheets. As we train them in the process, I do expect that we will eventually be able to have players running the bullpens with coaches able to simply focus on coaching instead of dual-hat work as a data-recorder and coach. When we get to that point, we will likely also run more than one bullpen at a time which will greatly increase our data collection.
The Bullpen Tracking Sheet
Every bullpen is recorded, whether we have technology to provide velocity and other details or not. Simply tracking location, type of pitch and the number of pitches is going to useful over the long haul. In fact, if you don’t want to record or track velocity, just tracking the base data is going to help.
We start by filling out the top part of the bullpen tracking sheet. It’s straightforward to name the pitcher and catcher. Date is also an obvious one.
When I coached Little League, we’d have 2 games a week and I had a pitcher throwing a bullpen every inning. At the start of the season, that pitcher was always the one throwing the next inning. By the end of the season, with players throwing 2, 3 or 4 innings, some of those pitchers were just getting work in. Whether we had 1 or 2 practices in addition to the games, there was never enough practice time. By throwing a bullpen during the game, the player got focused attention and practice one more time. Some coaches will argue that the time is better spent in the dugout learning ‘situational baseball’, but we’d rather have them develop their physical skills whenever we can.
”Record By” was added when it was realized that if a player was marking balls and strikes in the bullpen, they might not have the same criteria as the pitching coach.
The initial version of the sheet didn’t number every pitch, so when left to untrained hands (parents or players) sometimes the pitches weren’t recorded in the order that we expected. So, every cell now has its number from 1-20.
I recommend new pitchers or fielders who may not pitch throw exclusively from the stretch. Learn one thing at a time.
For pitch #5 in this bullpen, the Changeup (CH) was thrown from the windup and came in at 52mph. It started high and inside but finished in the top of the strike zone. Needless to say, this was good movement (GD MVMT). You can mark it any way that makes sense to you. I know my own notations have changed in the last year and will continue to evolve. For example, I’ll likely move that W over below the pitch type.
Not every bullpen is the same, but once the pitcher is loose, we have a quick conference on what the pitches are going to be. We might script 5 pitches of three types (FF, CH, CB) and try to throw 60% from the stretch. With some players, like me, it can 100% from the stretch, for simplicity.
The person recording marks the pitch type and whether it’s from the windup or stretch before each pitch, so everyone is on the same page.
At the bottom of the sheet, there is a section for Session Notes. We record the ball/strike ratio for each pitch type here, showing the velocity range (outliers in parentheses). We add comments about the bullpen session, such as a summary or praise or a cue that might be useful. Since the player gets this paper copy of the sheet, they’re likely to retain it to understand their own capabilities and progress.
At the end of the session, we take a photo of the tracking sheet so it can be loaded onto the iCloud page for that pitcher.
iCloud Notes
We create an iCloud Notes page for each pitcher on our team. As pitch tracking sheets are created, each gets added to the bottom of the page. We add notes on the session, evaluations of the player and plans for future use (in games or in bullpens) at the top of the page. For both sets of information, the most recent image or text is placed at the top to allow quick reference.
Thus far, having them stored on the same page, but with images and text separated seems to provide the most value for us. Since we’ve just had this in use for a single fall season, we’re not yet sure whether to have new pages for new seasons or if all the data for a single pitcher should remain on one iCloud Notes page.
Finally
Hopefully, this gives you a good idea of the logistics, technology and paperwork to set up and record information about your team’s bullpens. I do expect to write more on the process and on what we’ve done when evaluating the data. For me, probably the greatest asset is being able to review objective data and recorded video of our pitchers, rather than just relying on my memory of how well their bullpens went.
As I began using my pitch-tracking sheets, I found that I was feeling a little blind about the pitchers that I had warming up in the bullpen each inning. At my most organized, I had one assistant coach that served as the bullpen coach and I would ask him how the session went. Even though it was recorded using the PitchLogic ball, I wasn’t looking at any data when I considered sending in the reliever.
I had good data collection and some guidelines for number and type of pitches, I was only able to use it in retrospect to do an after-action review of the game and bullpen. I was able to discover and share insights with my pitchers – for example, that a high spin rate from one of my pitchers would coincide with a good outing. I didn’t have them use video because that got a little too complicated. I never knew how accurate they were throwing, other than generalities.
I came up with a basic bullpen pitch-tracking sheet. Room for 20 pitches and comments if necessary. It’s simpler than the pitch-tracking sheet for games, since there are no game details (count, runners, result) to worry about.
I’m now helping at practices with a 13u travel team and brought the sheets to a practice in which we did some short bullpens. The most important thing I learned was that it didn’t have enough guidance to how to fill it out. I had 4 pitchers and they rotated between camera, radar, pitching and the tracking sheet. It was a good session and it got me to improve the bullpen pitch-tracking sheet.
Sheet Header
In the header, it provides space to record your pitcher and catcher, as well as the inning and date for reference. It hadn’t occurred to me until our head coach, Sean Willingham, had a look at it that it was REALLY important to know who filled it out. It will almost always be our players recording the data and some players will record the strike zone far tighter or looser than others. If you don’t have them mark down who recorded the session, you might interpret the results incorrectly. It also forces some accountable when recording.
Pitch cells
There are four sets of five pitch cells to allow 20 pitches in a bullpen. While that’s more than I had the 11-year-olds throwing, a little extra seemed merited for older players. For bullpens that happen at practice, 20 pitches feels good for me, even when we’ve got the 14u practicing with us. If they’re throwing a bullpen instead of pitching, it would probably be useful to use two or more sheets. Then, have the pitcher take a break after each sheet, as though he was sitting while his teammates hit. Pairing pitchers on bullpens like this is a good way to simulate game usage.
Pitch type follows the little guide in the upper right (if you prefer FF and FT for 4-seam and 2-seam….) and the next big box is the velocity. Then, the important one for in-game bullpens is the 9 cells for the pitch location. The middle is the strike zone and I prefer they use an X to mark the location, being as granular or vague as their understanding merits. When recording pitches that have good movement, you can always use an arrow to show where it started and where it ended. At the bottom of each pitch cell is a grey box in which a note could be made, like “GRT MVMT” or track the virtual count (2-1, 0-2, etc).
Let me know if you find this useful or if you have editing suggestions. I am probably going to have the good folks over at Always Grind 365 print me some books full of them before the next ABCA. If you’ve read this far, you obviously like recording data on paper like I do, so make sure to check out their Pitcher’s Notebook and Catcher’s Notebook. I use both for myself when I play and will be working with getting our 13-year-olds to try them out this year.
and came in at 52mph. It started high and inside but finished in the top of the strike zone. Needless to say, this was good movement (GD MVMT). You can mark it any way that makes sense to you. I know my own notations have changed in the last year and will continue to evolve. For example, I’ll likely move that W over below the pitch type.
