Over 15 years ago, Dr. James Andrews, stated that there was an alarming epidemic of pitching injuries among high school players. In Andrews' opinion, it was the result of kids pitching too much--regular season, travel ball, fall leagues. My son, then a college freshman, was one of his patients. But, my son did not play summer ball or travel ball, and he never threw over 90 pitches in a game. IMO, the rash of injuries was primarily the result of the rise of biomechanics in pitching instruction that really took hold around 2000, pioneered by Paul Nyman. Nyman, an engineer, did detailed bio-mechanic studies of major league pitchers and initiated programs to help young pitchers gain speed. His star pupil, a Juco pitcher from Seattle, went from 78 to 92 MPH in less than a year. Pitchers changed their mechanics to increase speeds, but their bodies were not conditioned for the increased speed. My son changed his mechanics using Nyman's program to get the extra speed, gaining 7-8 MPH on his fastball in less than 18 months, but his shoulder muscles were not conditioned to handle the extra speed, particularly the strain on the labrum when the arm decelerated. Result: torn labrum. Nyman called me when he found out about the injury. We talked about it and I could tell that Nyman was almost as distraught as we were. A few months later, Nyman shut down his pitching instruction website. I think Nyman decided that he might get sued because of the alarming number of injuries incurred by his students. But, others used Nyman's studies, starting "pitching academies" that churned out flame-throwing pitchers. A few years later, I remember Harold Reynolds saying that when he was in the majors, you could count on one hand the number of pitchers that threw 95+. In the 2006 draft, 19 pitchers taken in the first round threw 95+. IMO, Paul Nyman was the driving force that initiated the dramatic increase in pitching velocity.
