Whether you follow Ted Williams, Charlie Lau, or even Coop DeRenne’s hitting approach, the hitter must understand his/her strengths and weaknesses. As stated, each approach has certain elements, but in the end a hitter will combine many of the elements into his/her own kinetic energy.
DeRenne states that when a hitter is successful, components such as visual, biomechanics, and exercise science are the contributing factors (DeRenne, 1993). A major league hitter swings a bat at 1000 meters/per second. The only way that this happens is if the hitter has a sound kinetic swing chain. This chain has links and each link relies on both the previous and post connections. Once a hitter ends his/her weight shift and the lead foot lands and begins to rotate around a firm front leg, one kinetic link ends and another starts.
