Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Declan Stevens
The Overview
Alright Declan, 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 57th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
What The AI Analysis Tells Me
Declan, here's what jumps out at me — you're throwing 82 mph, but based on your physical profile, our AI model predicted you'd be around 78.7 mph. That's a +3.3 mph difference, which tells me your mechanics and motor patterns are already working in your favor. You're squeezing more velocity out of your body than most athletes with similar builds. That's a huge positive.
Your mechanics efficiency is at the 75th percentile — that's excellent. You're converting your athleticism into velocity very well. There may be small refinements we can make, but the big wins will come from improving your physical profile.
Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Vertical Jump
+1.8 mph
Current: 27.0" (63th %ile)
→
Target: 31.2" (93th %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
+1.8 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.
Vertical Jump 225
+1.8 mph
Current: 18.6" (40th %ile)
→
Target: 22.0" (70th %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.
These three priorities alone = +5.4 mph potential
Can You Hit Your Target?
Here's the best part — the math works. You need +8.0 mph to hit 90, and the improvements above give you +10.4 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. 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 Left Grip Strength and Left Hip External Rotation. Together, these account for about 0.8 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: Left Hip Flexion, left shoulder 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.
