News: Our Pitching Philosophies

Here at Driveline Mechanics, our inspiration for what constitutes safe and effective pitching mechanics comes from Dr. Mike Marshall, Chris O'Leary, and RPM Pitching. I've done a lot of research myself, and though I hold no advanced degree in any biology-related field, I've come to believe that some derivative of the above pitching analysts/coaches are what I should be teaching at the high school level and what maximizes performance while keeping arms healthy.

However, there are many people out there who disagree - the analysts at The Hardball TimesSaber-Scouting, and other writers that I'm not aware of. And that's fine! Recently, the people at Lookout Landing (an SB Nation blog about the Seattle Mariners) have responded quite negatively to a FanShot I posted about Brandon Morrow. Their main source for believing that analyzing a pitcher's mechanics for predictive value for injury is worthless comes from a post entitled Biomechanics and You, by Graham of USS Mariner.

In the aforementioned post, Graham says:

I’d say it’s more likely that we should all be taking commentary on pitching mechanics and their relationship to injury with a boulder of salt.

And I responded with:

I’ve said over and over again that my analysis of pitching mechanics and injuries that I predict as a result of those mechanics are subject to small sample size – in this case, the n-value is literally always 1. Yes, people share similar traits in anatomy, but we are all built differently enough that the mere definition of acromial line is subjective. However, I do think I have a strong concept of correlation between the two, and with my pitcher risk database project forthcoming, we’ll eventually know if my theories are on the right path.

Nick Mueller pointed out in a recent post that no one should take our work as the gospel, and I couldn't agree more. Our work is something that should be compared to the work that everyone does out there as well as combined with independent research on your own.

Sabermetrics took over baseball because a few intelligent and brave individuals dared to question the validity of batting average, RBI, and HR totals as gospel. They were eventually right on a lot of things, and research continues to this very day - the most recent tool being the wonderful PITCHf/x data that MLBAM releases to the public for free. Our writers study and analyze it and hope to make useful conclusions from the data, just as I research pitching mechanics and hope to quantify what causes (and by extension, how we can prevent) injuries to pitchers while not sacrificing the performance required to make the grade in the MLB.

We at Driveline Mechanics encourage you to come to your own conclusions, and we definitely don't want you taking anyone's word at face value, including our own.

EDIT: I would like to add that Graham lives in Seattle, where I also currently reside. I have sent him an email and hope to communicate with him in the near future, with perhaps a joint interview for our respective sites, as I'd love to expand my knowledge on the topic.

One thing

I don’t understand is the backlash associated with injury risk when it comes to pitching mechanics. I have no doubt that poor mechanics will lead to injuries. The hatred towards the study and understanding is the hardest thing to overcome.

Denial is not just a river in Egypt...

I can understand it from a certain point of view. Here’s Morrow, the great hope for the future, they see him throwing 99 mph with sick movement and a great breaking pitch…oh yeah, this guy has to be an ace!

Then along comes Kyle saying “this guy’s arm action is risky” (note that he did not say “Morrow will blow his elbow out” or or “this guy’s a lock for labrum surgery”) and first they think to themselves “well, wouldn’t the front office have caught that?” Then comes “the front office had to have caught it!” And finally, we get “the front office had to have caught it; therefore, Kyle must be wrong!” All the while not realizing that the Mariners may have fully realized he was risk when they drafted him (remember, even though it was for different reasons, Aaron Crow was considered high-risk by even the Nymanites and he went in the first round this year). I was EXACTLY like this about Pedro Martinez a few years back with a different individual (my old baseball coach who got me into pitching mechanics) and a different team (New York Mets).

But what gets me though is that Graham says there is no correlation between pitching mechanics and injuries. Even Paul Nyman thinks there’s a correlation between pitching mechanics and injuries (though it is vastly different from our concept, it is out there). You have it from both sides…there’s a correlation between mechanics and injuries. His statement is (excuse the terrible pun) straight out of left field. With that said, I don’t want to insult the guy and would welcome him aboard at this site and others so he can learn about pitching mechanics and their correlation to arm injuries.

Strawmen are pushed around easily.

Read Graham’s article. There are a lot of things that no one knows about how the tendons and muscles work, down to we don’t even know enough about the materials that compose them. Pitching mechanics is a “big picture” application of biomechanics work that hasn’t been done yet.

All that’s being done right now is assuming. It’s like the dark ages of medicine, you look at someone and try to tell what they have wrong with them by where it hurts and what the wounds look like. It may work some of the time, but all it is is uneducated assumptions. You’re the witch doctors of baseball.

All Graham pointed out is that none of you know at all what you are talking about when you make assumptions. Not Kyle, not Marshall, not Nyman, not even Graham. No one.

Until scientists figure out the basics of what our bodies are made out of and how they interact, talk about “mechanics” relating to injury is all junk science waiting for the next new age movement.

One fallacy deserves ad hominem

"All Graham pointed out is that none of you know at all what you are talking about when you make assumptions. Not Kyle, not Marshall, not Nyman, not even Graham. No one.

Until scientists figure out the basics of what our bodies are made out of and how they interact, talk about "mechanics" relating to injury is all junk science waiting for the next new age movement."

Just because we don’t know the tensile strengths of every ligament or tendon (by the way we do know what they are made of), it’s not as though you’re going to talk us down by saying “you don’t have enough data to make assumptions.”

Pitchers are, as of this very second, pitching, and because some people prefer to be pragmatists rather than idealists, they’re going to analyze that pitching and use the information that is available to them to form conclusions about it. It’s true that before modern medicine people often made asinine attempts to cure diseases or made wild assumptions about their roots. That didn’t stop advances in medicine occurring every century from zero AD on and before that intermittently since ancient egypt. It’s also true that despite the fact that modern medicine dominates treatment of illness now, people (idiots) still turn to superstitious and ineffective medicines that were made up and have no basis in evidence. We now have modern medicine and science to help us in our work toward biomechanical progress, and we also have evidence.

When, for example, a pitcher like Mark Prior is labeled as mechanically perfect (even bringing this like up shows the weakness of Graham’s argument: It was uttered by Prior’s own coach and is contradicted by all evidence) and that pitcher breaks down, something must be wrong. If a common mechanical element is repeatedly correlated with arm injuries (inverted w in this case) then we have evidence against its effectiveness. Often, correlation does not require causation, however, because we are acting pragmatically, this is the kind of evidence we have to use.

That doesn’t mean we are just making blind guesses about what “looks right” or what motion has the best results. This is not made up. This is based on evidence, and if you present evidence to actually argue a point made by Kyle, that would really strengthen your case. Instead you’ve made a personal attack, judging credentials that you aren’t privy to (judging by your numerous posts of inane one-liners in lame chat threads on USS Mariner, I doubt you’re a mechanical expert yourself).

Space.

It's a problem we face.

So we never go anywhere.

We just stay in one place.

Wow.

A lengthy post that waffles back and forth between arguing for and against your point. Let’s rebut it point by point, just because I have to wait for my code to compile.
1) I’ve seen nothing that shows we have any data on how living connective tissue reacts under stress, but I will concede your second point. Labs in the past few years have been growing their own tissues that are close to what the human body produces, and they do have the base materials they are made of, and can in fact make their own.

they’re going to analyze that pitching and use the information that is available to them to form conclusions about it

Just like the dark ages. It’s not like you’re getting measurements or extracting data on what is going on inside a joint. You’re analyzing pictures and video. Great for looking for tweaks or gives or patterns, but not so good for telling whats happening that the video can’t see.

people (idiots) still turn to superstitious and ineffective medicines that were made up and have no basis in evidence.

Replace medicines with diagnosis and this is much like your so-called studies.

we also have evidence.

No you don’t. Show me the numbers. Show me something besides this looks like someone else that got hurt here, so he will.

even bringing this like up shows the weakness of Graham’s argument:

Way to prove that you didn’t read Graham’s post.

pitcher breaks down, something must be wrong.

That something could very well have absolutely nothing to do with the mechanics he uses. You don’t know any better.

If a common mechanical element is repeatedly correlated with arm injuries (inverted w in this case) then we have evidence against its effectiveness.

Incorrect. You have assumptions. It might be evidence if every pitcher that did a particular thing had the same problem. I would imagine you’ve never worked with scientists, because your justification for calling something evidence is appallingly low.

because we are acting pragmatically, this is the kind of evidence we have to use.

This is the point where you declare your evidence is bunk. Good work.

This is based on evidence, and if you present evidence to actually argue a point made by Kyle

So I’m supposed to counter the evidence that you yourself implied is assumption based with what exactly? More assumption based evidence? Sure. I’m sure I can find two pitchers with the same motions that have different injury outcomes (or even 4 or 5).

judging credentials that you aren’t privy to

Aren’t privy to? Do you even know what privy means? He has more credentials he’s hidden that aren’t on his bio page that he’s posted? I’ve seen them, and sorry if I don’t think that someone that hasn’t done any peer-reviewed work into the subject, worked for long stretches as an “analyst”, and otherwise has read up on the works of one Dr. Marshall, is qualifications on a subject like this.

judging by your numerous posts of inane one-liners in lame chat threads on USS Mariner, I doubt you’re a mechanical expert yourself

I’ll concede that I’m not an expert, but that’s sort of the point. No one today can qualify as an expert. I would argue that I know just as much about injuries as you do, maybe more so, because I’ve been the subject of a few knee injury studies over the course of my years, and I tended to ask a lot of questions of my doctors.
 And I don’t post as USSM, I post on a fellow SBN blog, Lookout Landing, as you could probably see if you actually read the things you say you have. And those “inane one liners” are called banter and discussion. There are threads on LL that are a chat room of sorts, and being those are the ones that have people in them when I am up (time difference and work schedule means I don’t catch many games and I’m not often around when the exciting stuff is posted), those are the ones the majority of my comments are in.

Congratulations. You’ve proven yourself to be just the creationist-in-a-baseball-hat that your first comment implied.

Don’t worry, I won’t be back to argue with your assumptions anymore. After reading most of the postings, it’s clear that many of you are in it just to be believers, and don’t really care if the “evidence” that is used it real or not. See you in the reality-based part of the world.

Sorry for the lack of reply on this.

I’m sure that those few reading can follow this 6 comment thread and can tell who I’m responding to.

Good luck with your “analysis”.

“Congratulations. You’ve proven yourself to be just the creationist-in-a-baseball-hat that your first comment implied.”

It’s funny that you use this line, because you are the one here acting like a religious nut. For instance, religious nuts are often seen arguing from ignorance: You might hear them saying that scientists didn’t know about radio waves until recently to prove that some other bullcrap waves exist. Or you can see them saying they have personal experiences to back up their outrageous claims.

“No one today can qualify as an expert. I would argue that I know just as much about injuries as you do, maybe more so, because I’ve been the subject of a few knee injury studies over the course of my years, and I tended to ask a lot of questions of my doctors.”

Sounds like an argument from ignorance backed up by bullcrap anecdotal evidence to me. That one is no religious nut: It’s you. Another favorite of the religious nut is that once they’ve used up all their tactics is to say that skeptics are too sad/stupid/closed-minded to be argued with:

“Don’t worry, I won’t be back to argue with your assumptions anymore. After reading most of the postings, it’s clear that many of you are in it just to be believers, and don’t really care if the "evidence" that is used it real or not.”

Wow, that’s pretty mature of you. By the way it’s also nice that you conflated “many of you” with me, hazel, the one person arguing with you. If you had gone so far as to look at the VERY LAST FANPOST that I’ve written, you’d have seen that it goes on at length lamenting the limitations of ASMI’s latest study. I want the numbers, and I want to throw them in your face, and it’s you and Graham that are making arguments from ignorance to back up a view that boils down to: We don’t know enough so no one knows anything.

Do you know what a theory is? It’s a model that is capable of predicting empirical observations or outcomes of testing.

So if someone were to say, form a theory that the inverted W contributes to shoulder impingement, well it would be a terrible theory because it contains too many arbitrary elements. However, once again, pragmatically speaking, because pitchers are throwing and getting injured every day we are forced to form theories and simply eliminate as many ambiguities as possible. The point is that falsifiable predictions are made exactly as they have been. Granted, this is really not quite scientific, because as you and I have said the numbers simply are not available, however this is as close as we’re going to get as of now (assumptions can only be limited), and you taking an analysis of Morrow personally and declaring the entire process pointless is not productive.

Space.

It's a problem we face.

So we never go anywhere.

We just stay in one place.

The article in question...

Whilst I did skim it enough to get a gist of what Graham was saying, I wrongly assumed that it was in direct response to Kyle. For that I am sorry. However, 1) Faux just proved that there are EXACTLY people who I described in my post and 2) reading Graham’s article carefully, it comes across as too light to make a conclusion and a tad hypocritical. He himself concludes that there is no correlation between pitching mechanics and injuries. But yet, he just wrote an entire article on how “no one can be sure of x, y, and z.” How then can he himself be sure that there is no correlation?

He seems to back down in the comments section…for example agreeing with one poster that while stating “Francisco Liriano has a risky arm action” is fine, stating “Brandon Morrow will probably get hurt in the rotation” is not. Thing is, there’s such a thin line between those two statements that it may as well not exist. Yes, Liriano had an arm injury, but why then does Graham agree with pointing out the arm action (and ignore tempo, finishing, etc.)? You can also hurt your arm by just having a terrible conditioning regimen. That in and of itself is acknowledging that something must be wrong with Francisco Liriano’s arm action; else why would it be “risky”?

Further, there’s a few comments where some are accusing people interested in pitching mechanics of making it sound “science-y” and putting up a boatload of data that makes their opinion valid. Well, I hate to ask this, but how is Graham any different? I’m sure Faux or someone like him will come back and point out his academic credentials. Sound familiar? Yes, that’s right, that’s the exact same thing that the Nymanites and the Marshallites do. Graham’s opinion is as valid in its presentation as Nyman’s, Mills’, Ellis’, Gomez’s Marshall’s, O’Leary’s, Kyle’s…you name it. But like all of them, he’s just one of many differing opinions out there. What makes him any different or “right-er”? He’s one of the very people he points out as having an opinion on pitching mechanics.

His opinion is simple, really; that there may or may not be a correlation between mechanics and injuries. But his dismissal of proper pitching mechanics as being the domain of internet gurus is patently absurd. Is Brent Strom an “internet guru?” Is Rick Peterson? Jim Hickey? Dan Warthen? Tom House? These are MLB pitching coaches (or in the case of Strom and Peterson, former pitching coaches that have gone on to other things and in the case of House, a college pitching coach at a rather prominent college). They believe in a correlation between mechanics and injury, even if some seem to be wrong about it based on their results. This is not the cult-like internet movement that Graham makes it out to be.

Honestly I just think Graham's frustrated with the tone of the debate and most of the people involved

Often, academic credentials are bogus, and often followers really are totally blind and utterly committed to an unquestioning loyalty to “the best system.” The evidence is dubious at best (especially the “evidence” of Marshalites and other internet types who make utterly outrageous claims like “an end to all arm injuries”), however, I agree that Graham is absolutely arguing both sides when he takes a Morrow analysis on an internet site that he supposedly doesn’t give any credence to personally while he talks about other pitchers as injury risks. Either we know nothing or we are on to something, every answer can’t be right

Space.

It's a problem we face.

So we never go anywhere.

We just stay in one place.
