Pitching Is a Skill and a Force Transfer Event

Pitching is one of the most precise and complex skills in all of sports. It demands rhythm, coordination, proprioception, and the ability to stabilize and sequence through the entire body under high load. But it's not just a skill expression. It is one of the most extreme acts of force transfer in athletics.

The kinetic chain, from the ground up, is responsible for redirecting thousands of newtons of force through the body and into the baseball. If you cannot produce force or manage how it moves through your body, you will break down or plateau. As Dan Cleather writes in Force: The Biomechanics of Training, the foundational principle of athletic movement is force. Skill does not happen in a vacuum. It is constrained by what your body is physically prepared to handle.

This is why I believe pitching is unique. It is both a high-skill movement and a high-force movement. You cannot fully separate the two. And you cannot express skill efficiently if the body cannot first absorb and redirect the force that pitching requires.

Why General Capacity Is Non-Negotiable

At the bottom of the Bondarchuk pyramid is general physical preparation. That base supports everything else. Without it, anything you layer on top, mechanics, drills, weighted balls, becomes fragile.

Hans Selye’s General Adaptation Syndrome and Verkhoshansky’s work on supercompensation show that capacity must be built through stress and recovered from systematically. Adaptation does not happen just because you do something “specific.” It happens because the body has the ability to respond to the training it is given.

A weighted ball is not dangerous because it is a weighted ball. It becomes dangerous when the athlete does not have the force tolerance, tissue quality, or technical organization to handle it. Without sufficient mobility, strength, tendon capacity, and joint integrity, the specificity of throwing becomes a liability.

Throwing is asymmetrical, rotational, violent, and it requires full-body sequencing. That level of complexity breaks down if the athlete does not have the physical foundation to support it. So before you ask how specific your training is, ask whether your system is ready for the stress that the specific skill demands.

The Problem With “Pitching-Specific”

Throwing is the most specific way to get better at throwing. That much is true. But not everything that looks like throwing actually develops the skill of pitching.

As Rob Gray explains in How We Learn to Move, motor learning improves through exposure to meaningful variability. This is the foundation of differential learning. The athlete becomes more skillful by solving different versions of the same problem under changing constraints. That is what builds robust movement patterns that hold up under pressure.

If a drill mimics the delivery but does not challenge the system to adapt, it may look specific but accomplish nothing. Specificity is not about resemblance. It is about transfer.

This is where the concept of affordances, originally introduced by James Gibson, becomes relevant. Athletes learn to move through interaction with their environment. Their perception and action evolve together. If the environment does not create real decisions and demands, it is not specific. No matter how much it “looks” like pitching.

“Repetition without repetition” is the phrase Gray uses to describe real motor learning. You are not trying to groove one pattern. You are trying to build the capacity to adapt within a pattern.

That is why physical capacity matters so much. Without it, you cannot execute the skill under fatigue, stress, or constraint. No drill will fix that.

Mechanics Emerge From Constraints

Mechanics are not installed. They emerge.

Every pitcher comes into the game with their own structure, their own movement history, and their own constraints. Trying to force an athlete into a pre-determined model ignores the reality that movement is an emergent property. Even when outcomes are consistent, the exact pattern used to achieve them is never identical.

As Bernstein famously showed in his study of blacksmiths, there is always variability. That variability is not a flaw — it is part of how movement solves problems.

Our job as coaches is not to impose mechanics. It is to influence them. To guide them. To create the conditions for the athlete to self-organize more efficient solutions based on who they are and what they need.

When you improve force tolerance, you expand movement options. When you build joint control, you clean up sequencing. When you design good constraints, the body starts to figure out better answers. You are not chasing a look. You are chasing an outcome

.

So, Should Pitchers Train Differently?

Yes, but probably not in the way it’s often presented.

Pitchers should train differently because the demands placed on them are unique. Throwing a baseball at game speeds, with precision and intent, over and over again, is one of the most physically and neurologically demanding actions in all of sport. It’s not just about throwing more. It’s about preparing the body to handle what the skill actually requires.

Training differently is not about adding more drills or tools. It’s about making better decisions, doing less with more intention. It is building a foundation that allows skill to emerge.

It means:

• Building general physical qualities first

• Developing the capacity to tolerate and transfer force

• Using constraints and variability to shape movement, not force it

• Respecting the mechanics are the result of individual structure

The question shouldn’t be what’s specific, but instead “what transfers?”

Because at the end of the day, if it doesn’t transfer, it doesn’t matter.

Thanks for reading.

For anyone looking to go deeper into the science and theory behind what I wrote about above, here are the books, blogs, and thinkers that influenced my perspective.

There’s a lot of noise in the baseball development space right now.
Everyone’s got a fix, a system, a drill that promises velocity. There’s endless talk about mechanics, tools, and hacks. And while some of it has value, a lot of it distracts from the only thing that really matters: on-field performance.

This blog isn’t about chasing the next new thing.
It’s about stripping away the excess, getting back to what actually transfers, and building pitchers who get on-field results, not just test well in a facility.

I’m relaunching this blog because I want to challenge myself to think more deeply, write more clearly, and sharpen what I believe.

What’s Changed

Two years ago, I started writing publicly because I wanted to explore ideas and share what I was learning as a coach.

Since then, I’ve coached more athletes, asked better questions, learned from coaches I respect, and refined the way I think about performance. The biggest shift has been internal. I’m more confident in how I view development, and much more focused on building systems that actually improve results where it counts.

I don’t care as much about what looks good in a vacuum. I care whether it shows up on the field. That mindset will guide everything I write here moving forward.

Who This Blog Is For

This is for serious pitchers who want to train in a way that reflects the actual demands of the game.

It’s also for coaches and performance staff who care about building systems that work over time. Systems that respect the individuality of each athlete, that scale, that evolve, and that don’t rely on gimmicks or shallow methods.

And honestly, I’m writing this for myself. I want to push my own thinking, hold myself accountable to my ideas, and to keep asking better questions.

What You Can Expect

This isn’t going to be a blog full of drills, mechanics screenshots, or oversimplified “keys” to velocity.

I’m going to write about the things I believe actually matter:

• Force production, skill acquisition, and how movement emerges under constraint

• The role of physical capacity and why general prep still underpins high performance

• How to integrate strength, throwing, and athlete individuality into a cohesive model

• And how to design development systems that are based in principles, not hype

I’ll over-explain. I’ll cite ideas from outside of baseball. I’ll contradict myself at times. And I’ll write like someone who cares more about understanding the truth than winning an argument.

Why This Matters

I’m tired of seeing young athletes get pulled into systems that chase complexity instead of building the fundamentals. I’m tired of seeing coaches prioritize drills that look specific over training that actually transfers. And I’m tired of seeing people confuse information with insight.

What we need is clarity.
What we need are systems built on first principles: force, adaptation, skill, and context, not on marketing.

Pitching is hard. Coaching it well is harder.
But if we’re going to do this the right way, it starts by being more honest about what works and what doesn’t.

What Comes Next

I’ll post when I have something worth saying. This is meant to be a place for depth, not frequency.

The first full post coming soon is titled “Should Pitchers Train Differently?” and it’s about rethinking what “specificity” actually means for the throwing athlete.

If you want to read about the deeper side of performance, and if you’re not afraid to challenge your own thinking, then I think you’ll get a lot out of what’s coming.

Let’s build something better.
