The Downright Filthy Pitching Series is a very in depth study of speed as it relates to the hitter's reaction time. Initial velocity is the speed of the ball as the radar gun sees it, perceived velocity is the speed of the ball as the minds eye sees it and Effective Velocity is the speed it actually is. Effective Velocity is the initial velocity plus the location effects of the pitch due to different locations having different reaction times. When a pitch is thrown at 90 MPH of initial velocity, it has 9 different possible speed zones it will enter depending on the location of the pitch. Within the strike zone, there are 5 time zones. A 90 MPH pitch can and does equal many different speeds, depending on where the pitch is located. This Series is about learning how to use that information to the fullest degree to maximize all of the ingredients that make pitchers truly Filthy. Over 10 years of study and testing of amateur hitters and two years of intense study of major league at bats in a 4 million pitch database have lead to some astonishing finidings. Hitters have an attention (an expectation of what pitch they are prepared for) that can be measured, tracked, predicted and even thrown around. Through the study of time based statistics or the statistics that are directly related to how well timed the hitter is to the pitch, we can show you how major league hitters statistics are dramatically affected when pitchers throw pitch sequences that take advantage of the optimum Effective Velocities and locations.
