Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Dylan Verdonk
The Overview
Alright Dylan, here's your Road to 90. Your overall profile is strong — you're in the 78th percentile across all metrics. This is a refinement phase, focusing on the small gaps that add up to big velocity.
What The AI Analysis Tells Me
Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Vertical Jump
+1.8 mph
Current: 25.0" (40th %ile)
→
Target: 27.0" (70th %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.
Right Grip Strength
+1.7 mph
Current: 113.0 lbs (66th %ile)
→
Target: 135.0 lbs (95th %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.
10-Yard Sprint
+1.5 mph
Current: 1.6s (64th %ile)
→
Target: 1.5s (94th %ile)
Why it matters: Your 10-yard sprint measures acceleration — first-step explosiveness. Pitching is all about that initial burst of power, not sustained speed.
How we fix it: The TopVelocity Sled is built for this — resisted sprints that develop first-step explosiveness. The 3X Program includes specific sprint protocols to improve your acceleration.
These three priorities alone = +5.0 mph potential
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 right shoulder external rotation and vertical jump. Together, these account for about 50.5 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: left ankle dorsiflexion, right ankle dorsiflexion (mobility), 10-yard sprint (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:
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
