Rotation Stability or Why Pitching Injuries Matter

I just came across and interesting article in Sports Illustrated online entitled Starting Point: Stability by Tom Verducci. It explains why pitcher injury prevention is so important at the major league level. Basically, it reduces your uncertainty and increases your odds of being successful.

Chris Carpenter's Inverted L

I just completed an analysis of the pitching mechanics of Chris Carpenter. While Chris Carpenter's pitching mechanics aren't as obviously bad as BJ Ryan's, Carp has a major Inverted L in his arm action. I believe that this is the root cause of Chris Carpenter's elbow and shoulder problems.

BJ Ryan: The Worst Timing In The World

I just completed an analysis of the pitching mechanics of BJ Ryan. BJ Ryan has the worst timing I have ever seen, due largely to a major Inverted L in his arm action. This is the root cause of BJ Ryan's elbow problems and will lead to problems with his rotator cuff and labrum.

Quick Look: Brandon Webb

I have been meaning to take a look at Brandon Webb for a while, and a recent e-mail by a D-Backs fan pushed me into action. I love the tailing, sinking action of Brandon Webb's fastball because it implies significant pronation which should help to protect his elbow.

I can't make up my mind about Brandon Webb's arm action, in part because I don't have enough information (e.g. no side view). His Pitching Arm Side (PAS) elbows gets somewhat high after he breaks his hands. It looks like it may then drop to below the level of his shoulders, but that is hard to say for certain from this view.
     I am concerned that I see signs of Hyperabduction in frame 20, but it's hard to say for certain. That Hyperabduction does seem to be less prominent in the 2006 version, which is good. However, I have to say that I am somewhat nervous about the health of Brandon Webb's PAS shoulder and wouldn't be surprised if it gave him some trouble in the next couple of years.
     You can see the same basic things in still photos of Brandon Webb.

The photo above shows how high Brandon Webb's PAS elbow gets after he breaks his hands.

The photo above demonstrates my concerns about possible Hyperabduction. Notice that Brandon Webb's PAS elbow is at, or just above, the level of his shoulders as his PAS forearm passes through the vertical, high-cocked position.

The photo above shows something that I didn't notice in the video. Brandon Webb locks his Glove Side knee as he releases the ball. I don't like this because it definitely increases the risk of knee and hip problems, and may increase the risk of arm problems.
     To sum things up, I have to admit that most of these things are pretty borderline; few are definitely bad. However, I will say that if I had to choose between Brandon Webb and Dan Haren, I'd take Dan Haren.

Why Mark Prior's Problems Persist

I am frequently been asked, both out of curiosity and skepticism, why I think I have been able to understand the root cause of Mark Prior's injury problems better than anyone else. I have long suspected that the difference is the approach I have taken, and last night I stumbled across this YouTube video clip of Mark Prior speaking to a group of Cub fans that confirms what I have come to believe. In this video clip, Mark Prior is asked what he is doing to try to fix the problems he has been having, and he replies with...

I've been watching a lot of film. I've been watching film back to almost high school, looking at different things, looking to see where things have gone wrong, to see where I kind of got off track as far as mechanics. That's probably led to a lot of problems.

In other words, Mark Prior and his coaches have been spending all of their time comparing the Mark Prior of today to the Mark Prior of the past.
     When you are troubleshooting a system -- and understand that I have spent much of my career troubleshooting complex computer systems -- there are a number of different approaches that you can take.
     The first approach, and the one that Mark Prior and his coaches have apparently taken, is to compare a thing to itself; to see if anything has changed over time. For example, if you have a computer that isn't working, the first thing to try is to see if some switch is, or isn't, flipped that used to be flipped. The problem with this approach is that it won't reveal the root cause of certain problems, especially those that take a while to develop and/or are due to fatigue and repetitive stress.
     A second approach is to compare a thing that is broken to a similar thing that is not broken and look for any differences. For example, if you have one computer that is broken, one way to try to fix it is to compare it to a similar, working computer and see if there are any differences between the two computers that might explain why one is working while the other isn't.
     During the course of my Pitcher Injury Analysis Project, I started out taking the first approach and compared pitchers to themselves. However, that approach didn't yield much in the way of clear results, so I shifted tactics and instead started comparing relatively injury-prone pitchers like Mark Prior to relatively injury-free pitchers like Greg Maddux.
     That immediately produced results.
     It turns out that there are obvious differences between the pitching mechanics of Mark Prior and Greg Maddux, and in my opinion those mechanical differences explain their very different fates.
     Until people in major league baseball stop using the first approach of comparing pitchers to themselves, they won't come to understand the root cause of many of the problems that pitchers face. That is because the root cause of many of the problems that pitchers face is not due to the fact that their mechanics have changed over time. Instead, the root cause of their problem is that those pitchers' mechanics have remained the same over time. In the case of pitchers like Mark Prior, their mechanics are slowly destroying their arms over the course of months or years, and the only way to restore those pitchers to health is to change their mechanics.
     Of course, to get to that point, you first have to get beyond the myth that Mark Prior has, and has always had, perfect pitching mechanics.

Cliff Politte's Inverted L

The Cardinals recently picked up pitcher Cliff Politte. A while back I did a photographic analysis of Cliff Politte's pitching mechanics to see if I could determine the root cause of his arm problems. It turns out that, like Chris Carpenter, Cliff Politte comes to the Inverted L position, with his Pitching Arm Side (PAS) elbow at or above the level of his shoulders and his PAS forearm hanging down vertically beneath it.
