JJ Santa Cruz

Alright JJ, here's your Road to 90. You're currently sitting at 87 mph, which means you need about 3.0 mph to hit your target of 90. Your overall profile is solid at the 60th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.

JJ, here's what jumps out at me — you're throwing 87 mph, but based on your physical profile, our AI model predicted you'd be around 83.6 mph. That's a +3.4 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.

Based on the AI analysis, here are your biggest opportunities to add velocity:

The AI also identified some mechanical variables from your motion capture data. There's about +3.5 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.

Here's the best part — the math works. You need +3.0 mph to hit 90, and the improvements above give you +6.4 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.

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.

The two biggest physical drivers for you right now are Left Hip Abduction and Left Hip External Rotation. Together, these account for about 0.2 mph of your velocity gap.

After that, it's about the supporting package: Left Hip Flexion, Left Hip Extension (mobility), Left Shoulder Flexion. These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.

Mechanically, the key focus is Dominate Arm External Rotation Front Foot Strike and Dominate Arm External Rotation Speed 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.
