Here is Dr. Mike Marshall's thoughts on this.... Dear Sir, That Dr. Raasch cares what Nolan Ryan has to say about anything proves that he is not a research scientist. That Dr. Raasch does not understand that baseball pitchers spend years to master their baseball pitching motion with regard to the height of the mound, such that, when they threw on lower mounds, their pitching rhythm would remain the same as they have used for years proves that he does not understand motor skill acquisition. Basically, this (research) study is ridiculous. The cause of the unnecessary stress on the pitching shoulder and elbow lies in the injurious flaws inherent in the 'traditional' baseball pitching motion, not the height of the baseball pitching mound. The cure for rupturing the Ulnar Collateral Ligament is for 'traditional' baseball pitchers to pendulum swing their pitching hand all the way up to driveline height in one smooth, continuous movement. The cure for irritating the front of the pitching shoulder is for 'traditional' baseball pitchers to move their pitching hand to driveline height at the same time that their glove foot lands. Therefore, lowering the mound would not decrease pitching arm injuries and practicing pitching off flat ground between pitching off the mound in competitive games, because of the muscle memory that baseball pitchers develop relative to pitching off mounds, would increase pitching arm injuries. Sincerely, Dr. Mike Marshall
