Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Caleb Sampen

📊 The Overview
Alright Caleb, here's your Road to 90. You're currently sitting at 82 mph, which means you need about 8.0 mph to hit your target of 90. Your overall profile is solid at the 59th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
🤖 What The AI Analysis Tells Me
Caleb, let me break this down for you. You're sitting at 82 mph right now, and our AI model — which has analyzed over 800 elite athletes — predicted 81.9 mph based on your physical metrics. You're actually beating that prediction by 0.1 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 48th percentile — there's definitely room to improve here. This isn't bad news, though. It means that as we work on your movement patterns and delivery, you'll see velocity gains without even getting stronger. The 3X Pitching Velocity Program addresses exactly this.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Body Weight +1.5 mph
Current: 187.0 lbs (57th %ile) Target: 212.9 lbs (87th %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.
Hip Rotation (Left) +0.7 mph
Current: 45.0° (3th %ile) Target: 60.0° (33th %ile)
Why it matters: Hip mobility determines how much separation you can create between your hips and shoulders — that's where velocity comes from.
How we fix it: The 3X Program includes daily hip mobility protocols — 90/90 stretches, hip CARs, and dynamic mobility drills. The Stride Excelerator also helps groove proper hip mechanics.
Hip Rotation (Right) +0.7 mph
Current: 45.0° (3th %ile) Target: 60.0° (33th %ile)
Why it matters: Hip mobility determines how much separation you can create between your hips and shoulders — that's where velocity comes from.
How we fix it: The 3X Program includes daily hip mobility protocols — 90/90 stretches, hip CARs, and dynamic mobility drills. The Stride Excelerator also helps groove proper hip mechanics.
These three priorities alone = +2.9 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 +5.6 mph, which would put you around 87 mph. That's a great interim target. The remaining 2.4 mph gap can be closed through consistent training, mechanical refinement, and maturation. It's going to take time and work, but it's doable.
🚀 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 ankle dorsiflexion and Left Hip Abduction. Together, these account for about 0.3 mph of your velocity gap.
Left Ankle Dorsiflexion +0.1 mph
Current 10 °
Percentile 50th
Target 14 °
To Gain +4 °
Left Hip Abduction +0.1 mph
Current 45 °
Percentile 50th
Target 49 °
To Gain +4 °
🔧 Supporting Work
After that, it's about the supporting package: Left Hip External Rotation, left hip internal rotation (mobility). 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:
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.
