Pitching instruction is moving in a "more is more" direction.

Instructors are trying to impress people with huge volumes of information and tens or even hundreds of drills.

The problem -- as I know from my own experience and from talking and listening to parents and new coaches -- is that, instead of being impressed, most people are feeling overwhelmed, and increasingly so. What most people want, at least to start, is a 30,000 foot overview of pitching, not to immediately get down into the weeds.

Knowing that I literally wrote the book on the elevator pitch, one day at a family dinner my brothers challenged me to put together an elevator pitch for pitching.

Chris O'Leary's Pitching Primer

While I presently spend most of my time thinking, talking, and writing about hitting mechanics, I got my start in baseball instruction researching pitching mechanics. I didn't want what happened to me to happen to my boys, both of whom are pitchers.

Chris O'Leary's 1-Word Pitching Clinic

If you asked me to give a pitching clinic, but limited me to one word, I'd have to choose this word.


I can't tell you how many pitchers I know and/or have worked with who threw in the mid-90s in high school and, now that I know them in college of the pros, are just trying to get back to 90 after experiencing an injury.

The body isn't designed to handle the rapid velocity increases that are being sold.

Chris O'Leary's 1-Pitcher Pitching Clinic

If you asked me to give a pitching clinic, but limited me to discussing just one pitcher, that pitcher would be Justin Verlander.

Justin Verlander

While I am a fan of David Price, I believe Justin Verlander has the best pitching mechanics of any active pitcher, and his return to those pitching mechanics explains his recent return to dominance.

Chris O'Leary's 1-Picture Pitching Clinic

If you asked me to give a pitching clinic, but limited me to one slide, this picture would be on that slide.

Justin Verlander

The reason I like this picture so much is because it illustrates a number of things...

  • That I think are important.
  • Are being coach out of kids.

Chris O'Leary's 1-Phrase Pitching Clinic

If you asked me to give a pitching clinic, but limited me to one phrase, I'd have to choose this phrase.

Pitching is throwing with less margin for error.

As a result, there is considerable overlap between what I teach in terms of pitching in throwing. In fact, I even go so far as to teach girls how to pitch like baseball players.

Chris O'Leary's 1-Sentence Pitching Clinic

If you asked me to give a pitching clinic, but limited me to one sentence, I would say the following.

Focus on the glove and let it rip.

I once ran out of pitchers in a game and had to talk a kid -- who had a good arm but who had never pitched before -- into pitching. Literally the only thing I told him was to, "Focus on the glove and let it rip." He got a couple of strikes on the first batter and then walked him. He did the same for the second batter. He managed to strike out the third batter and started to trust me. He then walked the fourth batter to load the bases, but struck out the next two to close out the game.

Chris O'Leary's 1-Concept Pitching Clinic

If you asked me to give a pitching clinic, but only let me talk about one concept, it would have to be this one.

Bottom-Up, not Top-Down.

People don't know how to teach throwing any more. Instead of teaching pitchers to throw with their hips, I see more and more throwing and pitching "gurus" teaching a top-down, glove-driven movement pattern that runs counter to how the body naturally wants to move.

Chris O'Leary's 10-Minute Pitching Clinic

There are a number of things I focus on when talking to pitchers of all ages, after I discuss all of the topics above.

First, Do No Harm

There are a number of cues and positions that people are selling out there that in truth are dangerous and are driving the pitcher injury and Tommy John surgery epidemic. These problematic cues and positions include...

A movement that I call the Tommy John Twist is an example of one such problematic movement pattern that is created by these cues.

Jose Fernandez's pitching mechanics are a perfect example of how and why this happens.

Jose Fernandez

Matt Harvey's pitching mechanics provide another example of an arm action that was ruined by the conventional wisdom about pitching mechanics.

Matt Harvey

Tragically, these cues are too often sold as Proper Pitching Mechanics by organizations like ASMI and the Mayo Clinic when they are anything but.

The Epidemic

Before I get into what pitchers should do, let me first address the elephant in the room, the pitcher injury and Tommy John surgery epidemic.

You know how pitchers are throwing harder than they used to? And at younger and younger ages? The root cause of the epidemic lies in the tricks that people are employing to create those velocity increases. They work by overloading the arm. In the short term, that yields a quick and significant velocity boost. In the long term, that dramatically increases the risk of injury.

As a result, if you care about more than just velocity, and are interested in creating starting pitchers and not just relievers, you need to be EXTREMELY careful when it comes to the cues you use or let be used with your pitcher(s).

Jeff Passan's "The Arm"

I discuss Jeff Passan's The Arm at length. One thing that he seems hell-bent on doing is spreading disinformation about the Inverted W. As a result, I have put together a piece that discusses The Truth About the Inverted W.

They Aren't Genetic Freaks

Dominant and durable pitchers aren't genetic freaks. They move similarly to each other and differently than pitchers who can't stay healthy.

Tom Seaver, Jose Fernandez & Nolan Ryan

To see this, just compare pictures of each at the same moment in time, like foot plant.

The Primacy of Timing

While there is still much unsettled debate about which, why, and whether arm actions are problematic, a recent study found that Timing problems do cause injuries.

Scott Kazmir

To stay healthy, it is critical that pitchers' pitching arms get up to what I call the Ready Position by foot plant.

David Price

Insisting on playing the role of the Tobacco Institute, Jeff Passan would have you believe the Inverted W is benign.

Nick Tropeano

In truth the Inverted W has and continues to destroy arms due to its tendency to create Timing problems.

Flat Arm Syndrome

If a pitcher's arm is flat when their front foot plants and/or their shoulders start to rotate, the load on the arm, and the risk of injury, increase dramatically.

Henderson Alvarez's pitching mechanics

Henderson Alvarez

For obvious reasons, I call this Flat Arm Syndrome.

Drop & Drive or Tall & Fall

The greatest trick Tom House ever played was convincing the world that Tom Seaver and Nolan Ryan moved differently.

That Tom Seaver was a drop and drive pitcher and Nolan Ryan was more tall and fall.

In truth, Tom Seaver and Nolan Ryan moved basically the same. 

Pitchers to Study

There are a number of active pitchers who I would, and in many cases have, literally driven hundreds or thousands of miles to see pitch so that I can film them with my high-speed camera.

The best of the best are...

  • Aroldis Chapman
  • David Price  
  • Justin Verlander  

Carlos Martinez has excellent natural pitching mechanics, but the Cardinals keep teaching him some problematic things and I sometimes see things that concern me as he goes out of his natural mechanics and into what the Cardinals think are proper pitching mechanics.

Aroldis Chapman

There are a number of other pitchers whose mechanics I like a LOT, and who I have also driven long distances to see, but who I rate a tick lower. Their Timing is good but not excellent, due to some hints of the Tommy John Twist.

  • Scott Kazmir  
  • Adam Morgan  
  • Tanner Roark  
  • Carlos Rodon  

In terms of the history of the game, pitchers I study obsessively include...

  • Mariano Rivera  
  • Nolan Ryan  
  • Tom Seaver  

In my opinion, Sandy Koufax had perfect pitching mechanics. However, he was also horribly overused and abused, and he makes the case that, no matter how good your pitching mechanics are, overuse will still get your arm.
