I have engaged in a number of formal and informal debates about pitching, pitching mechanics, and related topics with various people over the years.

Debates

The following pieces -- which are presentation in PDF form and webbooks -- give my side of the argument on a number of topics related to pitching and mechanics.

Xpert Summit

Most recently, I participated in a debate put on by Xpert Summit.

• Chris O'Leary Debates Pitching (REPLAY)

The topics I addressed included...

• Hooking the Rubber (PDF)
• Lead Leg Stability (PDF)
• Stride Length (PDF)

I also put together a short slide deck to adress one important topic that came up...

• Back Foot & Heel in Pitchers (PDF)

...as well as a short page that discusses...

• Back Foot & Heel: Koufax, Ryan, etc.

These presentations contain excerpts from my renowned...

• Flipbooks

Jeff Passan's The Arm

With the release of the hatchet job that is Jeff Passan's The Arm, and as I put together my thoughts about being part of The Arm, I want to be completely clear about my current position on the key topics related to the pitcher injury and Tommy John surgery epidemic, starting with the root cause of most problems...

• Timing

...and continuing on to the movement patterns that generally work by compromising pitchers' Timing...

• Flat Arm Syndrome 
• Premature Pronation
• Inverted W

Jeff Passan would have you believe my work has no basis in science, so you might want to read...

• The Science Behind The Epidemic
• Proper Pitching Mechanics?

For a guy who's work has no basis in science, my predictions are pretty accurate...

• The List: Pitcher Injury Predictions

Finally, in terms of the solution to the problem, I call it...

• Dominant & Durable

TIMING, INVERTED W, STRASBURG

The Inverted W is one of the chief culprits behind the epidemic because it tends to create a Timing problem, and Timing problems — not arm actions or positions — are one of the main reasons why pitchers get hurt. For example, Stephen Strasburg's pitching mechanics are problematic not (just) because of his Inverted W, but because his Inverted W predisposes him to something I call Flat Arm Syndrome. I discuss this topic at length in my Inverted W and Stephen Strasburg podcast.

PITCHER INJURY PREDICTIONS

I've made, and have become (in)famous for my pitcher injury predictions.

Alex Reyes makes me nervous. Elbow and also shoulder.
