Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Johnathan Kasten
The Overview
Alright Johnathan, here's your Road to 90. You're currently sitting at 76 mph, which means you need about 14.0 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
Johnathan, let me be real with you — this is actually exciting news. You're throwing 76 mph, but based on your physical metrics, the AI model says you should be around 79.4 mph. That 3.4 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 22th 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:
Vertical Jump 225
+1.8 mph
Current: 19.0" (41th %ile)
→
Target: 22.0" (71th %ile)
Why it matters: This metric has a direct correlation to pitching velocity based on our data from over 800 athletes.
How we fix it: The 3X Pitching Velocity Program includes specific protocols to target this. Combined with the TopVelocity training devices, you'll see improvement quickly.
Right Grip Strength
+1.8 mph
Current: 110.0 lbs (53th %ile)
→
Target: 125.0 lbs (83th %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.
Broad Jump
+1.7 mph
Current: 102.0" (71th %ile)
→
Target: 112.0" (95th %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.
These three priorities alone = +5.3 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 +10.1 mph, which would put you around 86 mph. That's a great interim target. The remaining 3.9 mph will require elite-level development — we're talking about pushing past 90th percentile on multiple metrics. Set 86 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. 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 hip internal rotation and Total Body Strength. Together, these account for about 4.7 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: left ankle dorsiflexion, Left Hip External Rotation (mobility), Left Rotational Power (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.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
