Proper Pronation Prevents Pitching Pain And Injury

by Brent Pourciau · June 15, 2011

Pitching Pronation Prevents Pitching Pain and Injury Pitching pain and injury, along with most elbow problems come from overuse and poor mechanics. If we narrow it down to elbow pain then proper pronation is usually the determining factor. Proper pronation of the arm at release is when the thumb finishes down. Notice here in the picture of me in my last minor league season I am finishing with goo pronation.

Improper pronation at release can be the result of poor mechanics and aggressive off speed pitches. For proper pronation to occur in the throwing arm at release the pitcher must extend the arm to release. The improper release of the throwing arm which would prevent proper pronation would be to pull the arm down to release. I find this to be a major misconception in the conventional wisdom of the game. Physics proves that during the velocity phase of the throwing arm, the pivot or elbow, must remain stationary until after release. This means the elbow must extend to release to prevent the elbow from moving down during the throw. This not only supports pitching velocity but protects the elbow from resisting high amounts of deceleration forces. Extending the elbow to release also protects the rotator cuff during the deceleration of the arm. This will allow more of the back muscles to get involved during the deceleration phase.

Pitching Pain and Injury Solutions

Dr. Mike Marshal built his entire coaching career around proper pronation of the throwing arm. He even went as far as to develop and entire approach to pitching based around this throwing arm pronation. This is because he ended his Major League career with a UCL tear before the famous “Tommy John” surgery. I believe Dr. Marshall went to far with this discover of proper pronation by turning it into a style of pitching. I do believe his pitchers who use this style or approach to pitching are protecting their elbows from injury but their pitching velocity is taking a beating in return. Using the 3X approach to proper pronation pitching will occur because the 3X mechanics trains the body to finish first and the arm to extend and finish last. The picture of me here illustrates the 3X approach to proper pronation. These mechanics will increase pitching velocity and protect the elbow and shoulder from extreme abuse.

I highly recommend replacing the baseball in the 3X Velocity System throwing drills with a football, if you are having issues with finishing with proper pronation. This is because you can not throw a spiral, with the nose down, with a football, if you do not finish with proper pronation.

Off speed pitches can also cause improper pronation because the wrist is usually rotating the opposite way at release during these pitches. This combined with the misconception of pulling down to release would compound the impact on the elbow and make a pitcher more vulnerable to elbow injury. It first starts with elbow pain and then it progresses into an injury. This is exactly how my arm began to breakdown. I had poor pronation along with an addictive curveball because it was almost unhittable. After 6 shots of cortisone in my elbow and rotator cuff surgery at 18, I never threw that damn thing again. I have even tried throwing it today and I can still feel the old wound from the many years of improper pronation. This is why I recommend less aggressive breaking balls for pitchers along with proper pronation training through the 3X mechanics.

This article is for every athlete out there. I am an athlete, who overcame a career ending rotator cuff tear in college, to pitch again and make it to minor league ball. I was told, I would never pitch as hard as I did before the tear. Over six years later, I topped out at 94 mph my last season for the San Diego, Surf Dawgs. That was more than 8 mph from before surgery. It was a long road and I am...

The curveball that you experienced problems with was the "traditional" supinated curve, not the Maxline Pronation Curve.

Honestly, I don't bother throwing either (I throw a good fastball, a very good sinker, and an occasional screwball)

Wow! I'm sorry if I came across as an arrogant coach, or having a chip on my shoulder. Seriously, that wasn't my intent at all! Please feel free to delete my comments if you disagree.

But, at the risk of ticking you off further…

You can find the other ways to throw the football as a training device here: http://drmikemarshall.com/BaseballPitchingInstruc…

-Click on "Football Training Program"

Note: It does involve the Marshall Arm Action, but generally speaking, it's worth look-see.

I realize that technically you didn't make the claim that pronation prevents UCL damage. I must have read too much into the last paragraph of your post. You mentioned how a badly thrown (although nasty) curve ball was the beginning of your elbow and shoulder problems. My bad.

Maybe this is a debate better suited for a private email?

  Brian, I am not a big fan of Dr. Marshalls approach to pitching. His football drills do not use his entire arm action but it does use a modified version of it which I feel these drills only work for those who use his pitching mechanics.
  
  Paul, I threw a supinated curve not the maxline. I have never used Dr. Marshalls pitching mechanics personally.

1. I do apologize for the broad generalization of Dr. Mike Marshal's career and the inaccuracy. I do appreciate your ego on my site though. It helps remind the pitchers reading this page how arrogant coaches really are.

2. I am happy to read that you agree with the use of a football to coach proper pronation but you forgot to give us the other ways to coach this pronation.

3. Can you support this claim with some evidence because I have not found any online?

4. "Pronation, while essential, does not prevent UCL ruptures, or shoulder injuries. Those injuries occur at different points in the delivery."

I never made this claim. I have only stated outside of this article that it helps prevent UCL damage.

If you would like to continue this debate it would be appreciated if you could remove the chip from your shoulder. Thank you!

Brent – I get a kick out of reading your thought and beliefs on pitching, but I have to call you out on this post. There are a few inaccuracies.

1. Dr. Mike Marshall did not rupture his UCL. His career did not end due to injury. He was actually in the Dodger dugout the day Tommy John ruptured his UCL.
2. While I agree that using a football to teach proper rotation of the baseball provides better feedback than a baseball, throwing a spiral with a football is not the only way to utilize the football in order to teach proper pronation. This is a Tom House generalization of something Dr. Marshall came up with a long time ago.
3. As a whole, Dr. Mike Marshall's pitchers have not "taken a beating" in the velocity category. I happen to know more than a few of "his" pitchers that have experienced a jump in their release velocity.
4. Pronation, while essential, does not prevent UCL ruptures, or shoulder injuries. Those injuries occur at different points in the delivery.

Sorry for calling you out on this one, but the mistakes are too glaring to ignore.
