Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Mac McSwain

📊 The Overview
Alright Mac, here's your Road to 90. You're currently sitting at 56 mph, which means you need about 34.0 mph to hit your target of 90. You're early in your development journey at the 29th percentile. At this stage, almost everything you work on will help — mobility, strength, power, and motor control all move the needle.
🤖 What The AI Analysis Tells Me
Mac, let me be real with you — this is actually exciting news. You're throwing 56 mph, but based on your physical metrics, the AI model says you should be around 59.2 mph. That 3.2 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 24th 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: 60.0" (1th %ile) Target: 90.0" (31th %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.
Lateral Broad Jump +2.0 mph
Current: 118.0" (2th %ile) Target: 149.3" (32th %ile)
Why it matters: This measures your lateral power — critical because pitching involves a massive lateral push off the rubber before you rotate.
How we fix it: The Stride Excelerator trains this lateral drive pattern specifically. Combine it with lateral bounds and the TopVelocity Sled for lateral resisted work.
Left Grip Strength +1.8 mph
Current: 50.0 lbs (1th %ile) Target: 95.0 lbs (31th %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.
These three priorities alone = +5.9 mph potential
⚙️ The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +7.0 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?
Let me be honest with you — getting to 90 mph is a big goal. The improvements I've outlined give you about +20.9 mph, which would put you around 76 mph. That's a great interim target. The remaining 13.1 mph will require elite-level development — we're talking about pushing past 90th percentile on multiple metrics. Set 76 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 broad jump and vertical jump. Together, these account for about 6.2 mph of your velocity gap.
Broad Jump +3.1 mph
Current 60 in
Percentile 4th
Target 102 in
To Gain +42 in
Vertical Jump +3.1 mph
Current 12 in
Percentile 3th
Target 28 in
To Gain +16 in
🔧 Supporting Work
After that, it's about the supporting package: left hip internal rotation, right hip internal rotation (mobility), Left Grip Strength, Right Grip Strength (power/stability). 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 Pelvis Rotation Speed Front Foot Strike and Trunk Rotation Speed Front Foot Strike. Most of the energy to the ball comes through the trunk, so trunk acceleration and sequencing are the big rocks to move.
Pelvis Rotation Speed Front Foot Strike +1.5 mph
Current Percentile 27th
🎯 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.
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
🚀 What's Next
At your age, development is rapid and everything helps. Train consistently across all areas — as your profile climbs, the plan will become more specific. Re-test every 3-4 months to track your progress.
