Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Caden Letcher

📊 The Overview
Alright Caden, here's your Road to 90. You're currently sitting at 81 mph, which means you need about 9.0 mph to hit your target of 90. Your overall profile is solid at the 51th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
🤖 What The AI Analysis Tells Me
Caden, let me be real with you — this is actually exciting news. You're throwing 81 mph, but based on your physical metrics, the AI model says you should be around 85.9 mph. That 4.9 mph gap? That's not a problem — that's POTENTIAL. It means once we clean up your mechanics and movement patterns, you've got velocity sitting there waiting to be unlocked.
Your mechanics efficiency is at the 13th percentile — and honestly, this is where the opportunity is. Your physical tools are there, but your delivery isn't converting them efficiently. The good news? Mechanical improvements often come faster than physical gains. Once we optimize your sequencing and timing, you'll see immediate velocity jumps.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Right Grip Strength +1.8 mph
Current: 105.0 lbs (44th %ile) Target: 118.9 lbs (74th %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.
Left Grip Strength +1.8 mph
Current: 100.0 lbs (36th %ile) Target: 110.0 lbs (66th %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.
Body Weight +1.5 mph
Current: 74.0 lbs (1th %ile) Target: 165.9 lbs (31th %ile)
Why it matters: Mass equals gas. Bigger athletes generally throw harder because they have more tissue to generate and transfer force. It's physics.
How we fix it: The 3X Program includes nutrition protocols for adding functional mass. Structured calorie surplus with adequate protein, paired with the strength training to make sure every pound you gain is useful.
These three priorities alone = +5.1 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 +9.0 mph to hit 90, and the improvements above give you +11.5 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. Your mechanics efficiency score tells me there's velocity sitting on the table right now. The 3X Program will teach you how to sequence your body properly and transfer all that force into the ball. 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 Left Grip Strength and Left Hip Abduction. Together, these account for about 0.5 mph of your velocity gap.
Left Grip Strength +0.4 mph
Current 100 lbs
Percentile 42th
Target 113.8 lbs
To Gain +13.8 lbs
Left Hip Abduction +0 mph
Current 48 °
Percentile 65th
Target 49 °
To Gain +1 °
🔧 Supporting Work
After that, it's about the supporting package: Left Hip Flexion, Left Hip Extension (mobility), Left Rotational Power (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 Front Foot Strike and Dominate Arm External Rotation 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 Front Foot Strike
Current Percentile 64th
🎯 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.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
🚀 What's Next
Hit these targets, re-test, and the system will update the next set of variables to chase. This is iterative — each evaluation narrows the focus as your profile improves. Plan to re-evaluate in 8-12 weeks.
