B) Twist or snap your wrist: In this brief pitching video I explain this myth in greater detail. If you twist your wrist right before release of the baseball you will experience elbow problems in the long run. In fact, you will know that it is wrong to throw the ball like this to begin with because your arm will tell you it’s wrong. Why do pitcher’s continue to throw like this? Again, this method works for some pitcher’s because it does impart rotation on the ball. The wrong rotation, but pitchers find success with it so they continue to use it.
Both partners will begin in a standing position, facing forward so athletes are side to side, each with one end of the KB Powerbands. The athlete performing the shoulder prevention exercises will put their hand or a towel high in their armpit, bring their elbow to their side, and make a 90 degree angle at the elbow. Holding the KB Powerbands athletes will maintain this position with their arm and begin to rotate just the bottom portion of their arm (forearm and hand) away from their body. It is important athletes do not let their elbow move away from their body. Keeping the elbow tight will allow athletes to experience the full benefits of the pitching drill. Athletes will move the hand away from their body at a normal speed while taking 4-5 seconds to control the resistance as the hand moves back toward the body.
It is important when throwing a slider, or any breaking pitch in baseball, not to come "around" the baseball. When the pitcher "comes around" the ball, the pitcher puts extra tension on his pitching arm to throw that pitch. A slider is thrown with a regular arm motion, just like a fastball. Slider movement is a direct result of the fingertip pressure and grip. The pitcher may visualize throwing his fingers at the catcher in order to improve follow through and finish the pitching motion.
I learned this pitching drill from Coach Scott Birchler who was a high school coach at our rival high school but as I got older and made the transition from player to coach, he helped me a lot. This pitching drill that he taught me is great for any pitcher who wants to be more consistent with their curveball or slider and fixes two of the biggest problems in guys who throw these pitches, dropping that elbow and not finishing the pitch.
