Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Jaxson Black

📊 The Overview
Alright Jaxson, here's your Road to 90. You're currently sitting at 79 mph, which means you need about 11.0 mph to hit your target of 90. Your profile is in the 42th percentile overall, which means there's significant room to grow. The good news? Every improvement you make will translate to velocity.
🤖 What The AI Analysis Tells Me
Jaxson, let me break this down for you. You're sitting at 79 mph right now, and our AI model — which has analyzed over 800 elite athletes — predicted 76.4 mph based on your physical metrics. You're actually beating that prediction by 2.6 mph. That means your mechanics are doing their job. You're not leaving velocity on the table from inefficiency.
Your mechanics efficiency is at the 70th percentile — that's excellent. You're converting your athleticism into velocity very well. There may be small refinements we can make, but the big wins will come from improving your physical profile.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Broad Jump +2.1 mph
Current: 96.0" (44th %ile) Target: 102.0" (74th %ile)
Why it matters: Your broad jump is one of the best predictors of pitching velocity because it measures your ability to produce horizontal force — exactly what you need off the mound.
How we fix it: The Stride Excelerator is perfect for this — it trains the exact horizontal force production pattern you use in your delivery. Combine that with plyometrics, bounds, and the TopVelocity Sled for resisted stride work.
Lateral Broad Jump +2.0 mph
Current: 140.0" (11th %ile) Target: 152.0" (41th %ile)
Why it matters: This measures your lateral power — critical because pitching involves a massive lateral push off the rubber before you rotate.
How we fix it: The Stride Excelerator trains this lateral drive pattern specifically. Combine it with lateral bounds and the TopVelocity Sled for lateral resisted work.
Left Grip Strength +1.8 mph
Current: 105.0 lbs (49th %ile) Target: 120.0 lbs (79th %ile)
Why it matters: Grip strength is the end of the kinetic chain. All that force you generate has to transfer through your hand to the ball.
How we fix it: Farmer carries, dead hangs, wrist work, and specific grip training in the 3X Program. This also helps with spin rate and command.
These three priorities alone = +5.9 mph potential
⚙️ The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +3.6 mph worth of mechanical improvements available. These are things like trunk rotation speed, pelvis rotation, and arm timing — exactly what the 3X Pitching Velocity Program is designed to fix. The Trunk Excelerator specifically trains that rotational sequencing, and the Stride Excelerator grooves the lower half mechanics. This is where the real velocity unlocks.
🏆 Can You Hit Your Target?
Here's the best part — the math works. You need +11.0 mph to hit 90, and the improvements above give you +12.8 mph of potential. This is achievable. It's not going to happen overnight, but if you commit to the training and stay consistent, 90 mph is absolutely in reach.
🚀 My Recommendation
Based on everything I'm seeing here, here's what I recommend: The 3X Pitching Velocity Program is exactly what you need. This isn't just a throwing program — it's a complete system that addresses mechanics, strength, power, and motor learning all in one. You've got some physical development to do, and the 3X Program includes the strength and power protocols to build that foundation while you're learning elite mechanics. To accelerate your results, I highly recommend using the TopVelocity training devices that are built into the program: The Trunk Excelerator teaches you to generate and transfer rotational power through your core — this is where velocity lives. The Stride Excelerator builds explosive leg drive and proper stride mechanics, which is the foundation of the 3X approach. The Impulse Ground Force Trainer develops your ability to create force into the ground, and the TopVelocity Sled builds the specific strength patterns you need for a powerful delivery. These aren't gimmicks — they're tools designed to train the exact movement patterns that separate high-velocity pitchers from everyone else. Combine them with the 3X Program and you'll see results faster than training alone.
💪 Your Top Physical Priorities
The two biggest physical drivers for you right now are broad jump and Body Height. Together, these account for about 0.6 mph of your velocity gap.
Broad Jump +0.6 mph
Current 96 in
Percentile 50th
Target 102 in
To Gain +6 in
Body Height +0 mph
Current 72.5 in
Percentile 63th
Target 72.8 in
To Gain +0.3 in
🔧 Supporting Work
After that, it's about the supporting package: left ankle dorsiflexion, Left Hip Abduction (mobility), Left Lateral Broad Jump, Left Grip Strength (power/stability). These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
⚙️ Mechanical Focus
Mechanically, the key focus is Dominate Arm External Rotation Maximum External Rotation and Dominate Arm External Rotation Speed Maximum External Rotation. Most of the energy to the ball comes through the trunk, so trunk acceleration and sequencing are the big rocks to move.
Dominate Arm External Rotation Maximum External Rotation +0.3 mph
Current Percentile 58th
🎯 Your Action Plan
Movement Cues:
"Shin down, leverage, drive — use the ground."
Training Priorities:
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
🚀 What's Next
At your age, development is rapid and everything helps. Train consistently across all areas — as your profile climbs, the plan will become more specific. Re-test every 3-4 months to track your progress.
