Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Jace Newkirk
The Overview
Alright Jace, here's your Road to 90. You're currently sitting at 85 mph, which means you need about 5.0 mph to hit your target of 90. Your overall profile is solid at the 62th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
What The AI Analysis Tells Me
Jace, here's what jumps out at me — you're throwing 85 mph, but based on your physical profile, our AI model predicted you'd be around 78.8 mph. That's a +6.2 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 in the 91th percentile — that's elite level. You're maximizing what your body gives you. At this point, adding velocity is about building a bigger physical engine because your delivery is already dialed in.
Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Left Grip Strength
+1.8 mph
Current: 110.0 lbs (58th %ile)
→
Target: 125.0 lbs (88th %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 (60th %ile)
→
Target: 1.5s (90th %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.
Body Weight
+1.5 mph
Current: 173.0 lbs (39th %ile)
→
Target: 195.3 lbs (69th %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 = +4.8 mph potential
The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +2.8 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 +5.0 mph to hit 90, and the improvements above give you +7.6 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're already in a good spot physically, so the 3X Program will help you refine and maximize what you've got. 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 Body Height and Left Grip Strength. Together, these account for about 0.3 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: Left Hip Abduction, Left Plantar Flexion (mobility). 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.

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.
