Over the last few days, I’ve been processing the results of a case study I just finished on the decline of @MLB starting pitchers.

I made this video to speak directly to pitchers, especially aspiring professional pitchers, because you deserve to hear this.

Case study: Top 3 pitchers drafted/signed each year since 2013 (all 30 orgs). In-org only (stop tracking once they leave).

• 1,134 pitchers | $1.27B bonuses
• 25.7% reached MLB (with drafting org)
• 6.4% reached 200+ MLB IP
• 38% arm injury | 28% major

The Top High School pitching prospects in this study undergo a major arm injury after just 159 professional innings.

Is your throwing pattern allowing you to reach your full potential?

And is your training program helping you improve that pattern?

A pitcher can become stronger, faster, and more powerful. Yet if the throwing pattern doesn't let them use those improvements effectively, how much has he truly gained?

Strength has value. So does speed. But neither guarantees that the body knows how to use them.

That is why I always go back to the timing of the throwing arm at foot strike; it is crucial to using leverage into the throw.

I define timing by the relationship between the throwing forearm and the spine at foot strike. Ideally, the two are closely aligned as the front foot meets the ground.

Why does this matter?

As the pitcher approaches foot strike, the throwing wrist accelerates upward. When the front foot lands, a properly timed arm can begin to slow and lag as the upper body's mass continues forward.

The lag allows the wrist to lay back as the shoulder approaches maximum external rotation.

The shoulder serves as a critical fulcrum, connecting the body's mass to the throwing arm. With proper timing, the arm is positioned to take advantage of that leverage as the elbow moves forward and the wrist accelerates toward ball release.

The throwing arm should not have to chase the body. It should be in position to receive its energy. This is why timing matters.

And why training should do more than build strength. It should help a pitcher make better use of the strength he already possesses.

Because the goal is not merely to become a better-trained pitcher.

It is to become a better pitcher.

TO THE NEXT GENERATION OF PITCHERS.

At 20 years old, I was pitching at Virginia Commonwealth University, on my way to becoming a first-round draft pick. My numbers were consistent, my execution was consistent, and I knew how to compete. By nearly every measure, what I was doing worked.

But that delivery had a shelf life.

Like many talented young pitchers, I understood how to produce results, but I had much more to learn about the movement responsible for producing them.

When my playing career ended in 2011, I began studying the deliveries of some of baseball's greatest pitchers throughout history. Over the next five years, I sought to understand the principles behind their movement, eventually developing the Delivery Value System. Since 2016, I've had the opportunity to apply and refine that methodology with pitchers at every level of baseball.

At 43, my delivery looks entirely different. Not because the task has changed, but because my understanding of it has.

We often hear there is no one way to throw a baseball. I agree. Every pitcher is an individual, with different physical characteristics, abilities, and experiences.

But individuality doesn't change the laws of physics. Understanding sequencing, true rotation, leverage, and energy transfer allows us to discover more effective ways of accomplishing the same task.

To the young pitcher throwing 90, 95 or 100 mph, don't confuse your ability to produce an extraordinary result with a complete understanding of how you produced it.

Be proud of your success. But remain curious. Study those who came before you, question what you think you know, and seek to understand the principles behind your movement.

Never allow what you can accomplish today to limit what you're willing to learn tomorrow.

I wish I'd understood these things when I was younger. My hope is that sharing what I've learned might help the next generation discover them sooner.

Built to Last.

This video is worth a watch, especially for pitchers, coaches, and anyone involved in managing a pitcher's workload.

Should a pitcher's arm really feel worse as the season progresses?

It's something we've almost come to accept in baseball. But does it have to be that way?

After throwing 40 innings in college and another 25 innings in the @uspbl , Kerry Collins was experiencing something different.

His shoulder range of motion was improving. His velocity was increasing. His arm felt better than ever.

How did he get there?

In this video, Will Fox sits down with Kerry to review three months of shoulder range-of-motion data and discuss what changed along the way.

Great work guys.

Dante Zamudio’s season changed dramatically during the 2026 @uspbl season.

Over his first 24.1 IP:
9.25 ERA | 2.05 WHIP | 53.9% strikes | 7.03 BB/9

Over his final 37.2 IP:
1.67 ERA | 1.14 WHIP | 61.6% strikes | 3.82 BB/9

So how did he do it?

In this video, Dante answers that question in his own words.

He talks about finding consistency, understanding his process from week to week, being willing to ask questions, staying open-minded, and continuing to make adjustments until he found what worked for him.

And that leads to the bigger question:

What does it take to be successful in the @uspbl ?

Dante’s season is a great example of what that can look like.
