Justin Verlander's injury.

What happened?

In sum, JV broke as a result of an ill-conceived effort by pitching coach Ron Wolforth to fix a phony flaw called Forearm Flyout. An effort that was TWICE preceded by episodes of Triceps pain.

Warning signs that were ignored.

Justin Verlander's Injury

If it ain't broke, don't fix it.

It's such a basic rule of thumb.

Yet it was violated, breaking Justin Verlander, my favorite pitcher.

Justin Verlander

JV's the pitcher I tell pitchers to study and emulate, if not copy.

Or he used to be.

So what happened?

Why did Verlander have Triceps problems?

Twice?

In 2015 and 2020?

Why does Verlander now need Tommy John Surgery?

The answer can be found in my tweets.

And in the Conventional Wisdom about pitching mechanics.

Ron Wolforth

After coming off of a Cy Young season in 2019, Justin Verlander was told by a pitching instructor named Ron Wolforth that he needed to change his pitching mechanics — to become more consistent with the Conventional Wisdom about pitching mechanics — if he was going to last.

Wldorth's rationale was that JV had a flaw called Forearm Flyout that he had to fix if he wanted to keep pitching beyond 40 years of age.

The problem is that was a complete misdiagnosis.

And, generally, a TERRIBLE idea.

And I said as much, starting in November 2019.

I immediately noticed those changes in March 2020.

Completely predictably, that led to arm problems.

Twice now.

Verlander & Duffey

The change was initiated by an instructor named Ron Wolforth, who has the ear of Verlander, and who thought JV did the same thing as Tyler Duffey.

Tyler Duffey

So Wolforth told JV he needed to change before he broke.

Justin Verlander

The problem is Wolforth's analysis was — obvously — flawed.

Tyler Duffey

As a result, Wolforth moved Verlander from an ideal pattern to a problematic one. A problematic pattern that is entirely consistent with the Conventional Wisdom about pitching mechanics.

The same Conventional Wisdom that explains why modern pitchers throw harder but can't stay healthy.

As a direct result.

Verlander vs. Duffey

Justin Verlander's arm problems start with Ron Wolforth and his concept of (Pitching) Forearm Flyout, which Wolforth illustrates using Tyler Duffey of the Twins.

Tyler Duffey

Wolforth a few years ago diagnosed Verlander with (Pitching) Forearm Flyout and prescribed the Connection Ball as the cure.

The problem is that, like prescribing antibiotics to a patient who doesn't have an infection -- an anology I use in Pitching MRSA to explain the problem with the Tommy John Twist -- Wolforth's prescription didn't FIX the problem.

Because the problem didn't exist.

And, worse, but as a result, CREATED a problem.

Justin Verlander had problems with his Triceps.

Twice.

Long-Arming

Historical photos of Justin Verlander, from his time with the Detroit Tigers, show that, while JV WAS a Long-Armer, he NEVER had a problem with (Pitching) Forearm Flyout.

Justin Verlander

Ron Wolforth, I guess, confused Verlander's Long-Arming -- which many people are prejudiced against for reasons most can't explain -- with (Pitching) Forearm Flyout.

As for why people don't like Long-Armers like JV, I can't find a reason, much less a good one.

Tyler Duffey's Problem

Don't get me wrong.

What Tyler Duffey does is BAD.

Tyler Duffey

But it's not (Pitching) Forearm Flyout.

Tyler Duffey

Rather, Tyler Duffey has a Timing problem as a result of a particularly bad version of what I call the Tommy John Twist.

Tyler Duffey

See how Tyler Duffey Points the Ball at Second Base? While his pitching arm is extended?

That's bad.

And creates a major Timing problem.

His arm is LATE.

Ridiculously late.

Disastrously late.

But it's not Pitching Forearm Flyout.

And it's VERY different than what Justin Verlander does.

Or did.

Justin Verlander's Mechanics

As I discuss at length in my analysis of Justin Verlander's pitching mechanics, at no time has Justin Verlander ever employed the Tommy John Twist.

Justin Verlander

JV has never Pointed that Ball at Second Base.

Justin Verlander

Instead, and as pictures show, Verlander points the ball at THIRD BASE, which is what pitchers do naturally.

Justin Verlander

What got Justin Verlander into trouble is the elbow angle changes -- flexion rather than extension -- that Wolforth had JV make.

How Wolforth took Justin Verlander from Long-Arming to Short-Arming.

For reasons that are historically indefensible.

And that led to his elbow problems.
