Strasburg's Injury

This was not a total surprise to baseball people as Strasburg was signed even though it was widely known that he had mechanical flaws. In some ways it's very similar to the signing almost twenty years ago of Todd Van Poppel, another pitcher with a plus, plus fastball. He had mechanical issues coming out of high school. In his case, his landing open and not using his lower body effectively would lead to arm problems as well. It was only a matter of time when scar tissue would build up in the rotator cuff group, and he would never throw with the stuff he had coming out of high school.
The next player on the break down list is Bryce Harper. The general consensus is that he'll develop potentially career ending back problems due to muscular imbalance, degenerative vertebrae, and arthritis caused by the thousands of reps of hitting in the cage and throwing at such a young age during his physical development.
As a person interested in the scouting and player development side of professional baseball, sometimes enthusiasm over prospects can make one forget that baseball, at least at this level, is a business.
