My son is a RHP and is 6'3"...with a weight of 160 pounds...His mechanics are sound. He continues to work out. He has been experiencing lower to side back pain...he had an MRI--nothing wrong. The orthopedic Doc said there is nothing wrong...except there is... He has been having some physical therapy on his glutes which are very tight....any advice or help on this would be great as he does not want to give up pitching; however he may have to if he cannot get this under control..
