Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Jaxson Mayo

📊 The Overview
Alright Jaxson, here's your Road to 90. You're currently sitting at 65 mph, which means you need about 25.0 mph to hit your target of 90. You're early in your development journey at the 24th percentile. At this stage, almost everything you work on will help — mobility, strength, power, and motor control all move the needle.
🤖 What The AI Analysis Tells Me
Jaxson, let me break this down for you. You're sitting at 65 mph right now, and our AI model — which has analyzed over 800 elite athletes — predicted 62.8 mph based on your physical metrics. You're actually beating that prediction by 2.2 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 67th percentile — that's solid, right around average for our database. You're neither leaving a ton on the table nor maximizing everything. This is a good sign because it means improvements in BOTH your physical profile AND your mechanics will translate to velocity.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Broad Jump +2.1 mph
Current: 62.0" (1th %ile) Target: 90.0" (31th %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: 120.0" (2th %ile) Target: 149.6" (32th %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.
Vertical Jump +1.8 mph
Current: 15.0" (1th %ile) Target: 24.0" (31th %ile)
Why it matters: Vertical jump measures your explosive power — your ability to generate force quickly. This directly translates to how hard you can drive off the rubber.
How we fix it: The Impulse Ground Force Trainer develops your ability to create force into the ground explosively. Pair it with box jumps, depth jumps, and Olympic lift variations in the 3X Program.
These three priorities alone = +5.9 mph potential
🏆 Can You Hit Your Target?
Let me be honest with you — getting to 90 mph is a big goal. The improvements I've outlined give you about +13.2 mph, which would put you around 78 mph. That's a great interim target. The remaining 11.8 mph will require elite-level development — we're talking about pushing past 90th percentile on multiple metrics. Set 78 mph as your first milestone, crush that, then we'll re-evaluate and map out the next phase.
🚀 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 vertical jump. Together, these account for about 5.8 mph of your velocity gap.
Broad Jump +2.9 mph
Current 62 in
Percentile 4th
Target 102 in
To Gain +40 in
Vertical Jump +2.9 mph
Current 15 in
Percentile 4th
Target 28 in
To Gain +13 in
🔧 Supporting Work
After that, it's about the supporting package: left hip internal rotation, left shoulder external rotation (mobility), Left Grip Strength, Right Grip Strength (power/stability). These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
🎯 Your Action Plan
Movement Cues:
"Shin down, leverage, drive — use the ground."
Training Priorities:
Build Mass
Calorie surplus + structured strength phases. Mass equals gas — you need more raw material.
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.
