Part of the problem the medical practioners are dealing with that they don't understand is the "hormonal macho complex" that is so embedded in the game of baseball.
You see it with the idea that a player never shows "pain" when they are "hit" by a pitched ball.
What are the players graded on, read the pro scout rating system. Isn't it about how fast, how far, and how hard a ball can be thrown, hit or, how fast a player can run.
None of these measurements are in themselves detrimental to an adult athlete who has reached his full growth, but when it is being applied to youngsters whose growth plates are just reaching maturity, and HS players are being measured by radar guns, with a urgency to "push it" with draft status and rankings on the line, you can see why players are coming more under the surgeons knife.
What is causing all of this?...money. Money is the motive behind all of these injuries. Money for sholarships, money for bonuses, and money for big contracts.
The reality...you are not going to reduce any of the increases in player injuries as the money gets more attractive and the competition for it gets stiffer. In fact, I predict that player injuries will increase more with the younger players as has already been experienced by the data presented in this article.
My recommendation is for youth associations to pass rules that prevent children from competing for more than one sport and one team per season. That would be a start in the right direction.
