Baseball Analytics For U15 Coaches: Useful Data Without Trackman

Why I Stopped Chasing Pro-Level Data

I coach U15 baseball. I also build web stuff and love numbers, so of course I went down the baseball analytics rabbit hole.

For a while I obsessed over the same metrics pro teams use. Attack angle. Spin rate. Hard hit percentage. I had spreadsheets that looked like NASA mission control.

The problem: I did not have Trackman. Or Rapsodo. Or Hawkeye. I had a beat-up field, limited practice time, and kids who still forget their belts.

So I stripped everything back. What can I track with almost no budget that still moves performance? Three things made the cut.

• Exit velocity
• Strikeout rate
• Walk rate

Everything else is optional. These three actually change how I coach, how players train, and how we talk about progress.

The Only Tech I Actually Use

Here is my full "analytics stack" for U15:

• Pocket Radar Smart Coach (you can use any basic radar gun)
• Printed scorecards I made in Google Sheets
• A cheap clipboard and a pen
• Occasionally, my phone for slow-mo video and to photograph the scorecards

That is it. No subscriptions. No laptops at the field. No one waiting for an app to sync before the next pitch.

The constraint is good. It forces you to decide what you will actually look at during and after a game. You cannot track everything, so you pick what matters.

Exit Velocity: The Most Useful Number In Youth Hitting

I think exit velocity is the most honest feedback a young hitter can get. The ball does not care how pretty the swing looks. It only cares about how fast it leaves the bat.

For U15 I am not chasing college numbers. I just want to know:

• Is this kid consistently hitting the ball harder than last month?
• Does their game performance match their practice numbers?
• Do swing changes show up in exit velocity, or just in how the swing looks on video?

How I Actually Measure Exit Velocity

I use the radar in three specific contexts.

1. Controlled cage sessions

Setup:

• Coach or machine throwing at a steady speed
• Player gets 10 swings that count
• Radar behind a net or L-screen, directly in line with the ball flight

Rules:

• No swinging at obvious balls
• Any complete miss still counts as one of the 10
• We only write down the top 3 exit velocities and the average of those 3

I track it on paper like this:

Player: Noah (U15)
Session date: 2026-04-20
Top 3 EV: 79, 76, 75 mph
EV-Top3 Avg: 76.7 mph
Swings: 10
Contact: 8

That last line matters. A kid who hits one ball at 82 and whiffs 5 is not a better hitter than the kid who hits 75 all day with barrels.

2. Tee and front toss benchmarks

I know tee work can be a lie. Kids groove a perfect pitch, swing out of their shoes, hit big numbers, then disappear in live ABs.

I still measure it, but I treat it as a "raw power" number. Not a game performance indicator.

For each player I keep three simple benchmarks:

• Max tee exit velocity
• Max front toss exit velocity
• Max live toss or machine exit velocity

If the gap between tee and live gets too big, that tells me something. It usually means timing and pitch recognition, not strength or swing mechanics.

3. Game contact samples

Live games are messy. You cannot get every ball. You do not want a radar gun in kids' faces between pitches.

So I keep it simple. Every once in a while, when a kid gets a real barrel, one of us on the coaching staff is ready and gets the number.

I do not announce it to the whole dugout. I just jot it down on the back of the lineup card:

Game EV notes:
Noah: 2B to LF line, 77 mph
Lars: F8 deep CF, 73 mph

Over a season that gives me enough data to answer one key question. Does this player hit the ball in games as hard as they do in practice? If not, I know where to look.

What I Ignore About Exit Velocity

I do not chase average exit velocity for every ball put in play. Too much admin for youth ball.

I rarely talk about launch angle with U15. If they consistently hit the ball hard in the air, I consider it a win. I can see it with my eyes. I do not need a perfect number.

I also never compare kids to pro benchmarks. That is a trap. I just compare each player to their own history.

Strikeout Rate: The Truth About Your Approach

When I look at a U15 player’s stat line, the first number I check is not batting average. It is strikeout rate.

Strikeouts tell me more about approach and pitch recognition than almost any other stat we can track cheaply.

How I Track Strikeouts Without Extra Work

I do not use an app for this. I use a printed scoresheet that forces the scorekeeper to mark how each plate appearance ends.

Simple notation:

• K = strikeout swinging
• ꞱK = strikeout looking (we draw a little T or backwards K)
• BB = walk
• HBP = hit by pitch
• IP = ball in play (with normal scoring 6-3, 1B, F8 etc.)

After each game I spend 5 minutes with the scoresheet and mark a tiny dot next to each plate appearance that ended in a strikeout or a walk.

Then I tally it in a season log like this:

Player: Noah
Game 1: PA 4, K 1, BB 1
Game 2: PA 3, K 0, BB 0
Game 3: PA 3, K 2, BB 0
Season to date: PA 10, K 3, BB 1

Now I have the one number I care about:

Strikeout rate = K / PA

For this example: 3 / 10 = 30% strikeout rate.

What Is “Good” At U15?

I think anything under 15% strikeout rate at this age is excellent. Under 20% is solid. Over 30% is a red flag that absolutely needs attention.

The cutoffs are not scientific. They are just from watching years of youth games and tracking this stuff. Different leagues and pitching quality will move the numbers around, but the ranking holds.

The main thing is trend. If a kid starts at 35% and ends the season at 22%, that is a huge coaching win. Regardless of what their batting average looks like.

How Strikeout Rate Changes What I Coach

Here is a typical pattern.

• Kid has a pretty swing in practice.
• Exit velocity is fine in the cage.
• Game stats show 35% strikeout rate.

If I only looked at their mechanics, I might start tinkering with bat path or load. The strikeout rate pushes me in a different direction.

I ask questions like:

• Are they swinging at strikes, or chasing up and away?
• Do they understand the strike zone at all?
• Do they have any two-strike approach or is every swing max effort?

Then our work changes. More mixed BP. More tracking-only rounds. Situational hitting games where a strikeout costs the team.

Mechanics still matter. But if the ball is never contacted, exit velocity is just theory.

Walk Rate: The Free Offense Youth Teams Ignore

Walks are boring to talk about. Kids want doubles off the wall. Parents want hard contact. Pitchers want strikeouts.

I like all that too. But U15 pitchers give away so many bases for free. If your hitters simply learn to collect some of them, your offense jumps.

How I Track Walk Rate

Same system as strikeouts, same scoresheet. I do not make this complex.

Walk rate = BB / PA

For youth I think a healthy range is roughly 10 to 20% walk rate, depending on the league. Below 5% and I start asking if the kid is too aggressive or chasing junk. Above 25% and I check if they are freezing on hittable pitches.

What Walk Rate Actually Tells Me

Walk rate is not just “plate discipline.” It is also:

• Pitch recognition
• Confidence to take a pitch with two strikes
• Understanding counts and game situations
• Whether they are guessing instead of reading the ball

If a player has a low strikeout rate and a healthy walk rate, I am happy. They see the ball well and they own the zone. Now I push for more damage on pitches in their spot.

If a player has a high strikeout rate and a high walk rate, I get curious. They are clearly willing to take pitches, but still missing a lot. That usually points to timing issues or fear of swinging aggressively.

Combining The Three: A Simple Player Profile

When I put these three metrics together for each hitter, I get a simple picture.

Example player:

Max tee EV: 80 mph
Max live EV: 73 mph
Strikeout rate: 32%
Walk rate: 5%

I see a strong kid. Decent bat speed. But the game is moving too fast for him.

Plan:

• Less tee hero swings, more mixed BP
• Specific work on recognizing high fastball vs low fastball
• Count-based approach: forcing him to hunt a specific zone in advantage counts
• Game goal: reduce strikeout rate over the next 4 weeks, not chase batting average

Another player:

Max tee EV: 72 mph
Max live EV: 70 mph
Strikeout rate: 12%
Walk rate: 18%

This kid sees the ball. Makes contact. Just does not hit it very hard yet.

Plan:

• Strength and speed work tailored to rotational power
• More intent in the swing instead of just "touching" the ball
• Exit velocity tracking once per week to check if the strength work shows up

Same sport. Different problems. Without the numbers, you tend to coach both players the same way. That wastes time.

How I Keep Tracking Sustainable

Coaches burn out on analytics because they try to be an MLB analytics department on top of throwing BP, managing parents, and dragging the field.

Here is how I keep the process light enough to actually stick with it.

1. One radar session per week

We have one hitting practice where exit velocity is the focus. We rotate kids through the radar station. The rest of the week I leave it in the bag.

That single day still gives me more than enough data over a season.

2. One sheet per player for the season

I print a simple A4 for each player. It has:

• A small table for exit velocity benchmarks across dates
• A grid where I write PA, K, BB totals after each game

It lives in a folder in my bag. I update it after games and the weekly radar session. No apps. No logins. No dead batteries.

3. One focus per month

I do not hit kids with all three metrics at once.

Some months I talk mostly about strikeouts and walk rate. Other months I focus on exit velocity and quality of contact. The spreadsheet always has all the data, but the conversation stays simple.

What I Tell Parents And Players About The Numbers

Youth baseball can get weird with stats. You have parents filming everything, kids obsessing over showcase metrics, teams posting leaderboards like they are a pro academy.

I am not against posting numbers. I just want the kids to understand what they mean.

I explain it like this.

• Exit velocity is about how hard you hit the ball. It mostly reflects strength, bat speed, and contact quality.
• Strikeout rate is about your approach and your ability to put the ball in play.
• Walk rate is about how well you see the ball and whether you can stay patient in the zone.

Then I add the part they hate to hear. I do not actually care about any single game. I care about how the numbers move over weeks and months.

Once kids get that, they stop treating a bad day as a disaster. They start seeing it as a data point.

You Do Not Need Trackman To Coach With Data

Would I use a full ball-tracking system if the club bought one? Of course. I enjoy that stuff.

But I think a lot of youth coaches use the lack of tech as an excuse. You can do real, useful, actionable analytics with three cheap tools and a bit of consistency.

Track:

• Exit velocity a few times per month
• Strikeout rate every game
• Walk rate every game

Write it down. Look for trends. Coach the specific problem in front of you, not some generic idea of a "better swing."

The kids do not need a pro-level setup. They need a coach who pays attention.
