Pitching with injuries to other areas of the body will also affect a player’s biomechanics and change the way he delivers his pitch.  An ankle, knee, hip, or spinal injury can cause changes in the biomechanics of how a player throws and will put more stress on his arm.  Be cautious with these injuries, because at times the changes in the mechanics of the player can be very subtle; however, they can cause a significant amount of strain on a player’s pitching arm.

Rest is key. Overuse on a daily, weekly, and annual basis is the greatest risk to a young pitcher’s health. Numerous studies have shown that pitchers that throw a greater number of pitches per game, as well as those who don’t get enough rest between outings, are at a greater risk of injury. In fact, in little league baseball, pitch count programs have shown a reduction in shoulder injuries by as much as 50%. Setting limits for pitchers throughout the season is vitally important to their health and longevity in the game.
