Those of you who are familiar the analyses I have done of the pitching motions and mechanics of a number of professional pitchers know that I am not a fan of Mark Prior’s motion and mechanics.
I think they have contributed to his injury problems.
Just today I learned that Mark Prior is reported to be experiencing problems with his shoulder. Based on an analysis of his motion that I did of his motion back in December of 2005, this is something that I predicted would happen.
I believe that the problem is that, as he turns his pitching arm side forearm over, he bring his elbows both behind, and more importantly above, his shoulders. In the analyses I have done, I believe I have noticed a pattern of shoulder injuries in pitchers who do this.
