Key takeaways
- Scouting phrases are useful observations, but observation isn’t diagnosis.
- Turn every label into a better coaching question.
- The same miss can come from any of the 4 pillars. Check them all.
- Data and video give the coach better questions. They don’t replace the coach.
“He has a fast bat.”
Scouting describes what a hitter does; coaching figures out why it happens and what to do next. Turn every scouting label into a better question, check all four pillars and give the hitter one problem, one feel and one test.
Train it: Hitting Coach Certification →“She’s athletic in the box.” “He can flatten the bat.” “He holds his own against spin.”
Those can all be useful observations. But they aren’t coaching yet.
1. How scouts talk
FanGraphs’ Fall Instructional League notes are a good reminder of how baseball people describe hitters. About one 17-year-old outfielder: a fast bat, feel for hitting, athletic in the box, able to flatten the bat on a hard fastball up, holding his own against spin, sometimes expanding the zone.
The language is short because it has to be. That’s valuable information. But the coach’s job begins where the scouting phrase ends.
2. Observation is not diagnosis
If a hitter has a fast bat, what does that mean? Maybe he can catch up to velocity. Maybe he creates force. Maybe he has speed but doesn’t square the ball often enough. Maybe he has speed because he rushes, which makes him vulnerable to spin.
“Fast bat” doesn’t tell us which one is true. At AHD, we turn every observation into a better question.
| Scouting observation | Better coaching question |
|---|---|
| Fast bat | Can the hitter bring that speed to the right pitch and location? |
| Flattens the bat | Where does the hitter create his best contact window? |
| Long swing | Is he late, disconnected or making a poor decision? |
| Great athlete | Does the athleticism stay present through contact and finish? |
| Pull power | Can he still cover spin, velocity and the opposite-field window? |
| Expands the zone | Is it a recognition problem, a timing problem or a plan problem? |
LABEL → QUESTION
SCOUTINGIS NOT COACHING.
- Fast bat → on the right pitch?
- Long swing → late or disconnected?
- Great athlete → through contact?
- Expands → recognition or plan?
OBSERVATION ISN’T DIAGNOSIS.
3. The 4-pillar diagnosis
When we coach a hitter, we don’t reduce him to one phrase. We check all 4 pillars.
- The Swing: movement, sequence, bat path, adjustability and Mechanically Advantaged Angles (MAA).
- Strength & Explosiveness: force, speed, power and athleticism.
- The Hitting Processor: see it, recognize it, time it, decide and attack it.
- The Mental Approach: confidence, approach, focus and resilience.
The same miss can come from different pillars. A hitter late on fastballs may need a better forward move. He may need more strength. He may need an earlier visual plan. Or he may be afraid to be early because he’s still thinking about his last strikeout.
Assume the answer from one clip, and you coach the wrong thing very confidently.
4. Use data without being ruled by it
Bat speed, exit velocity, launch angle and video are powerful tools. They make coaching more honest. They catch patterns our eyes miss.
But tools don’t replace the coach. They give the coach better questions. The important one is always: what gives this hitter the largest margin for error for solid contact while creating maximum force and an effective bat-to-ball angle? That answer won’t be the same for every hitter.
5. A better video-review conversation
Instead of, “Your barrel is flat,” try this:
“On pitches at the top of the zone, you lose the barrel below the ball early. Let’s see if you can hold your athletic position, keep the hands and barrel above the ball a little longer, and attack the high heater without getting early on the breaking ball.”
Now the hitter has a specific problem, a specific feel and a specific test. That’s coaching.
THAT’SCOACHING.
- See it: scouting.
- Ask why: diagnosis.
- Check all 4 pillars.
- One problem, one feel, one test.
- Build the plan.

Quick answers
What is the difference between scouting and coaching a hitter?
Scouting describes what a hitter does. Coaching figures out why it happens and what the hitter should do next, then builds a plan and tests it.
What does “fast bat” mean in scouting?
It means the hitter shows good bat speed. It doesn’t tell you whether he brings that speed to the right pitch, squares the ball or rushes, so a coach still has to diagnose.
How should coaches use bat speed and exit velocity data?
Use data to ask better questions and catch patterns your eyes miss, but don’t let one number replace a full 4-pillar diagnosis of the hitter.
How do I give a hitter better video feedback?
Name a specific problem, a specific feel and a specific test, for example losing the barrel below the ball on high pitches, holding the athletic position longer and attacking the high heater.
Why is my hitter late on fastballs?
The same miss can come from different pillars. He may need a better forward move, more strength, an earlier visual plan, or he may be afraid to be early after his last strikeout. Check all four before you coach the fix.
