While I'm probably best known for my research into the Inverted W, the problematic but common arm action with the pretentious name, that is only a tiny fraction of my work.

ABOUT JEFF PASSAN'S THE ARM...
Jeff Passan's The ArmWith the imminent release of the hatchet job that I fear 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...

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

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

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

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

DOMINANT & DURABLE
While it's widely criticized, my approach to studying and developing pitchers is time-tested.
   Here's an overview.
   First, question everything the pitching mechanics industry says. Don't take anything for granted. Go back to the original sources. Read everything you can on biomechanics, kinesiology, and related fields. Keep up on the journal articles. Buy a high speed camera. Hell, buy four.
   Second, study great pitchers who had long careeers. Pitchers like Nolan Ryan, Tom Seaver, Mariano Rivera, Greg Maddux, and David Price. Look for commonalities. How do they move? Is it similar?
   Third, study pitchers who have had injury problems. Pitchers like Mark Prior, Jaime Garcia, Stephen Strasburg, Matt Harvey, and Jose Fernandez. Look for similarities. Do they tend to move similarly. Do they have similar flaws? Look for differences between the two groups.
   After 10 years of studying the similarities and differences between the Nolan Ryan's and the Mark Prior's, I have detected a number of patterns, patterns that I sum up in a new series of ebooks called Dominant & Durable.

TIMING, INVERTED W, & STRASBURG
Stephen Strasburg Flat Arm SyndromeThe 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.

DOMINANT & DURABLE
The best way to sum up my philosophy and my approach to studying and developing pitchers is with two words.

Dominant and Durable.

While most of the industry -- knowingly or now -- is focusing on developing relievers, my focus is on creating great major league starting pitchers; pitchers who throw hard with nasty stuff while also staying healthy. While some would say that's impossible, I am driven by the success of pitchers like...

  • Mariano Rivera
  • Nolan Ryan
  • Tom Seavers
  • David Price

...and my focus is on discovering and explaining how they became as good as they were and are, while still staying healthy.
   Along the way, I have come to understand the main causes of the pitcher injury and Tommy John surgery epidemic and why pitchers like Jose Fernandez, Matt Harvey, and Stephen Strasburg and others can't stay healthy.

DOMINANT & DURABLE: DAVID PRICE
Dominant and Durable: David PriceDavid Price's pitching mechanics are breathtaking. He is one of a shrinking number of pitchers who still generate velocity in the classic manner; with their entire body and not just their arm. Dominant and Durable: David Price, is a nearly 600 page breakdown of his pitching mechanics. I spent 2015 travelling around the country and collecting 120 fps video clips of David Price's pitching mechanics and assembling them into a exhaustively detailed flipbook analysis of David Price's pitching mechanics.

DOMINANT & DURABLE: NOLAN RYAN
Nolan Ryan: Dominant and DurableNolan Ryan was one of the most dominant pitchers of all time and maintained that dominance for 27 years. Dominant and Durable: Nolan Ryan is a nearly 700 page, extremely detailed photographic study and analysis of his pitching mechanics.

THE EPIDEMIC
The EpidemicThe Epidemic is my ongoing investigation into the root causes of the pitcher injury and tommy john surgery epidemic. It grew out of my efforts to keep my sons and their friends healthy -- to keep what happened to me from happening to them -- by applying my experience troubleshooting large computer systems to the problem of pitching injuries. Along the way, I also happened to learn a lot about troubleshooting hitters.

TIMING, INVERTED W & STRASBURG
Stephen Strasburg Flat Arm SyndromeThe 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.

JOSE FERNANDEZ
Jose Fernandez Flat Arm SyndromeA month before his elbow failed, I saw something in Jose Fernandez's pitching mechanics that I believed put his elbow at risk and tweeted my concerns. A month before his shoulder failed, I saw that Jose Fernandez was still doing those same things, and worse, and tweeted my concerns.

PITCHER INJURY PREDICTIONS
In addition to my tweets about Jose Fernandez, I made a number of pitcher injury predictions during 2015.

THE SOLUTION
I understand the current emphasis on velocity. It makes everything easier. The problem is, there is a difference between how modern pitchers are being taught to create velocity and how great, durable pitchers like Tom Seaver and Nolan Ryan created velocity. That difference explains the injury problems of Mark Prior, Matt Harvey, Stephen Strasburg, Jose Fernandez, and many others.

I have spent the past 10 years studying the pitching mechanics of Tom Seaver, Nolan Ryan, David Price pitchers who were both Dominant and Durable and incorporating those lessons into my DVDs and eBooks.

THROWING MECHANICS 101
As I explain in The Epidemic, one reason why pitchers are increasingly getting injured, and needing Tommy John Surgery, at increasing rates is due to how they were taught to throw. Throwing Mechanics 101 discusses proper throwing mechanics and how to develop them.

HITTING & THROWING BASICS
I am constantly asked if I have any products for younger players. As a result, I have created Hitting & Throwing Basics which is designed to get young baseball and softball players on track and, just importantly, help their parents and coaches keep them from getting off track.
