Fingers Always On Top Of The Ball?

 

A couple of times lately I have heard people talk about how important it is that pitchers always release the ball with their fingers on top of the ball (and that coaches should always change a pitchers arm slot to achieve this). I just completed an essay called fingers on top of the ball that examines the wisdom of this idea.

Kerry Wood And The Inverted L

Given that I've been spending a lot of time recently talking about the Inverted L, I thought I should put together an analysis of Kerry Wood's pitching mechanics.

Will Carroll Weighs In On My Ideas About Mark Prior

Will Carroll has weighed in on my thoughts about the root cause of Mark Prior's injury problems on Tango Tiger's blog. I can't say that I'm surprised that Will's more than a little skeptical about what I have to say.

All good...except wrong. The “video” he shows tells us nothing. Bad angles and poorer quality. Our eyes lie. Computer-aided models with motion capture and joint measurement are the state of the art. O’Leary’s pretty good with his eyes, but no ones eyes are good enough to see mechanics or calculate forces.

Needless to say, I disagree with a number of Will's points.
     First, the 3B angle I used in my analysis is pretty much the perfect angle (and height) to use when looking at a right-handed pitcher's mechanics. That's why I was so excited to get my hands on the clip.
     Second, I completely agree that the naked eye is simply not up to the task of breaking down a pitcher's mechanics. That's why I go through the video (and it is a video rather than a "video") frame by frame. While the frame rate (and resolution) isn't quite what I'd like, you can clearly see Mark Prior's arm action in the clip.

Third, you don't need a fancy computer system to observe the height of Mark Prior's Pitching Arm Side elbow relative to the level of his shoulders, especially in Frame 30. In fact, all of that fancy computer technology can mask as many things as it reveals and in some cases a nice clear photo is the best tool for the job. I can tell you as a veteran of the computer industry that the quality of the output of a system depends on how the system is designed and the assumptions that drive its design (i.e. garbage in, garbage out).

I’m as guilty as anyone of saying Prior’s mechanics were perfect. They were pretty damn good, but perfect was an exaggeration or a wishcast. Saying it in hindsight or Marshall’s “I told you so” when he predicted an elbow injury, not a shoulder injury, doesn’t count.*

* I would give Marshall more slack if he hadn’t been so specific as to the causation for what he said was the inevitable elbow injury, what he calls “forearm flyout.”

I'm not sure what Dr. Mike Marshall has to do with what I said about Mark Prior. I'm not simply parroting Dr. Marshall's ideas or saying things after the fact. Instead, in November 2005 in my photographic analysis of Mark Prior's mechanics PDF I expressed concerns about Mark Prior's shoulder (see page 2) rather than his elbow.
     It was that prediction that convinced me (and others) that I might be on to something and that this was a project that was worth continuing.

Scott Williamson and The Inverted L

I just completed an analysis of the pitching mechanics of Scott Williamson. His is an interesting story because it is similar to the stories of Mark Prior and Kerry Wood. Scott Williamson was a young pitcher who came out of the gate quickly but whose career was derailed by a serious mechanical flaw. In his case, that flaw was our old friend the Inverted L.

Mark Prior: A Different Perspective

I just completed an essay entitled Mark Prior's Pitching Mechanics: A Different Perspective. In this essay I compare and contrast the mechanics of Mark Prior, Greg Maddux, and Nolan Ryan using video clips of each.

Quick Look: Josh Beckett

Many people have been asking me for my opinion of Josh Beckett. At some point, I'm going to do a detailed video study of his mechanics. In the meantime, let me take a quick look at Josh Beckett's mechanics using some still photos.
     The bottom line is that Josh Beckett makes me somewhat nervous because of some suggestions of hyperabduction. Josh Beckett's elbow height is right on the borderline. What's more, what I think I see is that Josh Beckett's elbow starts out high and then stays high rather than starting out high and then dropping as Nolan Ryan's elbow does.
     However, Josh Beckett has had 7 solid, relatively injury-free years, which suggests that he may fall on the John Smoltz and Pedro Martinez side of the borderline rather than the Kerry Wood or Mark Prior side.
     What will be interesting is to see how Josh Beckett ages and whether he continues to stay injury-free or if, like Smoltz and Martinez, he starts to have injury problems as his career progresses.

In the photos above, you can see that Josh Beckett's elbows get relatively high after he breaks his hands. One thing to note is that this isn't a classic Inverted L with the forearm hanging down vertically. Instead, Josh Beckett's Pitching Arm Side (PAS) upper arm is starting to externally rotate.

As the photos above show, Josh Beckett's PAS elbow starts high as he breaks his hands. Josh Beckett's PAS elbow then stays high, in a position of hyperabduction, as his PAS upper arm externally rotates and his PAS forearm passes through the vertical, high-cocked position. I think this increases the risk that Josh Beckett will experience shoulder problems.

There are some similarities between the photos of Josh Beckett and the photos above of Freddy Garcia and Cole Hamels, both of whom have had shoulder problems, and those similarities make me nervous.

However, I will be the first to admit that this not a totally firm concern. If you look at photos of Tom Glavine, you will see that his PAS elbow gets, and stays, relatively high. This suggests that, to a degree, there is some variability in terms of whether hyperabduction is always bad. This may be explained by the fact that there is variability in the human body, such as 3 distinct types of Acromial processes. This may explain why hyperabduction is a problem for some people but not for others.
