Downright Filthy Pitching - The Science of Effective Velocity (EV) is the study of baseball pitch speeds and how location changes the reaction time of the hitter. This science answers why pitchers are great one day and awful the next and why hitters fall into slumps with no answers. For the first time there is scientific proof that will teach pitchers how to go from having 'Nasty Stuff' to becoming 'Downright Filthy'. This book series shows you how to maximize the effects of every pitch in your arsenal, like time management for pitch speed usage. This is the first provable explanation for why certain pitches are swung on and missed one day and hit out of the yard the next. EV gives pitchers a detailed plan to help them maximize their deception............and yes, deception is now measurable and can be practiced. The only scientific pitch calling method has been implemented by Collegiate programs in baseball and softball throughout the country and with many Major League pitchers, catchers and coaches. EV has uncovered the truth behind some longtime myths about pitching. Find out why: 'Shorter Pitchers' may actually be far more deceptive' - 'Outside fastball is not the best pitch in baseball' - 'Keeping the ball down is killing you' and many other myths explained through this new set of goggles that has changed the game. You will never look at the game of baseball the same way again.
