I spent the early part of my career developing, testing, and troubleshooting large, complex computer systems. Since 2005, I have been applying those skills to the epidemic.

A Guided Tour of The Epidemic

I am best known for my research into the Inverted W, the problematic arm action with the pretentious name. However, since 2007, starting with my analysis of Mark Prior's pitching mechanics and contrary to pretty much everything Jeff Passan says about me in The Arm, I have been trying to make it clear that the root cause of the problems that pitchers so often experience, is NOT the Inverted W or other positions and arm actions.

Rather the problem with the Inverted W is the impact it can have on the thing studies have shown is critical to pitchers' health...

Things are getting worse due to the rise of a particularly severe Timing problem I call...

Aside from the Inverted W, which continues to get pitchers' elbows, the other most prevalent and problematic tricks and shortcuts are...

While Jeff Passan refuses to acknowledge it, there is in fact significant...

The scariest part? The hockey-sticking incidence of a serious problem called Thoracic Outlet Syndrome resulting from what I call the...

Pitching/Throwing-Induced Thoracic Outlet Syndrome is particularly troublesome because it causes blood clots, and blood clots can lead to strokes (or worse), as they did in the case of J.R. Richard.

Matt Harvey's pitching mechanics are a perfect example of all of these problems, and that explains his elbow and shoulder problems.

Why hasn't the pitching mechanics establishment come to see what I see? I discuss this topic in my piece on...

Why should you believe what I say?

I have a long track record of successfully predicting injuries to pitchers, including the injuries of...

Why am I the only person writing and talking about the epidemic?

At a minimum, a major problem is what Stuart Smalley would call...
