Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Chandler Marsh
The Overview
Alright Chandler, here's your Road to 90. You're currently sitting at 78 mph, which means you need about 12.0 mph to hit your target of 90. Your overall profile is solid at the 69th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
What The AI Analysis Tells Me
Chandler, here's your reality check. You're at 78 mph, and the AI model predicted 80.2 mph based on your physical profile. You're pretty much right where you'd expect to be. This means you're efficiently converting your athleticism into velocity — no major mechanical leaks, but also room to grow both physically AND mechanically.
Your mechanics efficiency is at the 29th 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:
Broad Jump
+2.1 mph
Current: 98.0" (54th %ile)
→
Target: 106.0" (84th %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.
Vertical Jump
+1.8 mph
Current: 26.0" (50th %ile)
→
Target: 29.0" (80th %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.
Total Body Strength
+1.4 mph
Current: 440.0 lbs (66th %ile)
→
Target: 610.0 lbs (95th %ile)
Why it matters: Strength is the foundation everything else is built on. You can't be explosive if you're not strong first.
How we fix it: The 3X Program includes a complete strength protocol — squats, deadlifts, rows, presses with progressive overload. The TopVelocity Sled adds sport-specific strength that transfers directly to your delivery.
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 +9.9 mph, which would put you around 87 mph. That's a great interim target. The remaining 2.1 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 broad jump and left hip internal rotation. Together, these account for about 3.1 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:
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
