Downright Filthy Pitching Book 1 introduces you to the world of Effective Velocity.  In a recent SABR Analytics Convention, Bill James (The Godfather of Sabermetrics) told the audience of researchers & media that if you want to change the game, you have to ask ‘Big’ questions.  Perry asked the biggest question of all, what causes hard hit balls? Effective Velocity answers that question using real ‘Science’.  Over a decade of empirical testing of hitters’ visual skills, reactionary abilities and Ev Tunnels showed hitters had a very limited ability to simply ‘See it & Hit it’ as they are instructed.

Book 1 teaches you the science behind what causes hard hit balls to happen and…… to avoid them.  90% of all hard hit balls are explained by Effective Velocity concepts.  Ev Tunnels, as described on MLB Network shows, is an Ev concept that was discovered at a time when MLB pitching coaches thought pitchers just ‘had’ deception……….or not.  There are many more elements discussed in this 1st of a 4 book series, that answers this biggest of all baseball questions.

Downright Filthy Pitching Book 2 – Hitters’ Attention is the second book of the Downright Filthy Pitching Series, describing the incredible discovery of the science of Effective Velocity.
Every hitter that ever stepped into a batters box is limited by the human condition. A fastball at the Major League level at 95 MPH travels to home plate in under .395 seconds. The average MLB hitter takes about 1/3 of that time or about .13 to .15 seconds to swing the bat, leaving only .267 seconds to see, identify the direction, identify the spin, which leads to identifying the pitch type, which leads to identifying the true reactionary speed of the pitch and finally to the decision to swing or not. When you factor in the time it takes for the brain to process the 2-5 possible pitch choices it could be, needless to say hitters are at a massive disadvantage.

Couple all of this with the fact that Ev efficient pitchers hide the identity of pitches even further by what they learned in Book 1 about Ev Tunnels. This refers to the fastball and the off speed pitches being in the same vertical and horizontal planes for 1/3 to 1/2 of the way to the plate. It is all but impossible for hitters to accomplish all of this and maintain their optimum swing mechanics. Of course hitters can ‘make contact’ with elite offerings but their production goes down dramatically.

After testing hitter’s reactionary abilities for many years, Inside Edge, the first data collection service for MLB teams, opened their database to see if the same things were happening at the highest levels. The statistics backed the findings in the reactionary tests at every point. Hitters’ Attention is very real and very misunderstood. Let’s shed some light on that subject and ‘Get Downright Filthy’.

Downright Filthy Pitching Book 3 – The Science of Pitch Sequencing is the 3rd book of the series on Effective Velocity. Book 1 is the introduction into the science and understanding of what Effective Velocity is all about. Book 2 describes the Hitters’ Attention or the human limitations of reacting to a pitch at such high velocities and the MLB studies that back the findings.

Book 3 describes how to implement Effective Velocity into your pitching approach in the simplest and most innovative and creative ways. This is the first book to show you how the baseball actually works to create different types of movements, to aid in deception. This is the first book to scientifically show how to gain a significant advantage against hitters by learning to sequence pitches in the most deceptive way possible. This book shows pitchers how to design their most effective pitch assortment and how to use them at maximum efficiency.

“I’m an old history teacher. In the history of man some innovations were so revolutionary that they forever changed the course of history. I believe Perry’s study and innovation of EV is changing and will change the game of baseball…it has certainly changed the way we attack hitters at Pitching Central.  Every day we have a choice. We can choose to stay current and ride the wave as the change alters the landscape…or stubbornly choose to be the cynic and swear the earth is flat…and be at the bottom
of the wave when it moves through. Regardless, an innovation of this magnitude will affect us either way.”
