These ARMory guys are putting up NUMBERS 🔥

Through 36 innings this year Parker Messick has been a lockdown arm every time he touches the rubber.

Nick Riedel has not let his foot off the gas for the entire season at Newberry going 10-0 over 86.1 innings.

Aidan Knaak has cemented himself in the history books with 300 career K’s at Clemson.

Tate McKee has been on an absolute tear since arriving at Georgia Tech in the fall of 2023. Now he’s in the history books with 200 career strikeouts.

What makes Parker special is his consistency. Perfect example of sticking to a plan and executing it. Day in and day out this guy came ready to work. Stoked to see his hard work this offseason paying off. Only the beginning 🧱🧱🧱

[Randy Sullivan MPT, CSCS @RandySullivanPT]

In 2014, I was speaking at a pitching coaches conference in Texas

The feature speaker was a track & field/rugby guy from The Netherlands named Frans Bosch.

Baseball crowd

Biomechanics nerds

Room full of coaches who make their living telling people how to move

He walks up, clicks to slide one, and opens with:

“The body shows very little interest in what the coach has to say.”

The room went silent

I literally leaned forward in my chair

By the time he was done, my world had tilted on its axis

I didn’t understand a lot of it

But I knew, deep down, “If he’s right… this changes everything.”

I was the next speaker

Topic: The anatomy of deceleration in pitching.

That’s like following Eddie Murphy with a knock‑knock joke

I gave my talk, quietly terrified that everything I was saying was garbage in light of what he’d just presented

Next morning, 8:00 a.m.

Drury Inn & Suites lobby

I’m building my gourmet continental breakfast: powdered eggs, waffle, bad coffee.

Conference restarts at 9

I see Bosch in the corner with fruit and yogurt

We make eye contact

I give the classic awkward coach nod

“Mr. Sullivan,” he says, motioning me over.
“I liked your talk.”

I sit down

We start talking motor learning and training at a level I didn’t know existed

He’s supposed to be on the way to the airport

His ride?

Trevor Bauer

Trevor is late

I don’t mind

We talk

And talk

Two hours go by like ten minutes

A few months later, his book “Strength and Coordination: An Integrated Approach” lands on my desk

I read it 6 times

Then I read every reference in the bibliography

I wasn’t just trying to learn the concepts

I wanted to know how he learned to think that way

I receive an invitation to Amsterdam to work with the Dutch National Program

We go even deeper

That trip led to the creation of our Annual Baseball Skill Acquisition Summit

It has been attended by hundreds of representatives from every MLB team

When he wrote “Anatomy of Agility,” Frans asked me to edit the English translation before it came out in the U.S.

He later wrote the foreword to my book “SAVAGE Revolution” and collaborated as I wrote “Integrated Anatomy of Pitching.”

That one delayed airport ride turned into:

A friendship

A new way of seeing movement

SAVAGE Training

The ARMory

And, ultimately, thousands of pitchers around the world training differently

All because Trevor Bauer was late to pick someone up

We call it hustle

Planning

Strategy

Networking

But underneath all of it, there’s this quiet, unpredictable force nudging things into place

It’s the missed flight, the awkward lobby breakfast, the “Hey, come sit with me” moment that changes your entire trajectory

You can’t manufacture it

But you can do this:

Show up

Stay curious

Sit in the front row

Say yes to the conversation

And be ready when your “Trevor is running late” moment shows up

Because from the outside it looks like an inconvenience

From the inside?

It’s the hinge your whole career swings on

Serendipity isn’t random luck

It’s what happens when preparation collides with one small, unexpected delay

It all happened because Trevor Bauer was late

Serendipity

[Ari Silverstein @ARMory_Ari]

Struggling with off-speed pitches?

“Pulling down the lampshade” won’t help.

What will is becoming a more efficient mover. Being able to train around universal movement attractors.

Hinge, Hip lock, close the front door. Become a better mover, not a better manipulator.

[Ari Silverstein @ARMory_Ari]

🧵 The best off-speed pitches, specifically CB/SL, don’t come from manipulation of the arm and hand but from rotation of the trunk.

The arm unwinds in an Iso-elastic state resulting from an optimal combo of flexion and rotation. So train elite rotation, not manipulation.

[Ari Silverstein @ARMory_Ari]

Verbal cues can:

•Disrupt kinematic sequencing of the body.

•Prohibit efficient transfer of energy up the chain and ultimately into the arm.

These inefficient movements can then lead to the need for manipulation. Remember, the movement creates the data.
