Baseball Pitches: A Modern Data Definition Book available on Amazon

Perfect for player development , amateur scouting , advance scouting , and broadcasters.

Pitches Clearly Defined

The main purpose of this course is take a first principles approach to defining distinct pitch types independent of the specific pitcher or the pitcher method, that can be detected when only using data. It also avoids the current ambiguity in pitch names, subjective names of pitches, and intent or technique-based pitch names, as used today.

Whether the pitcher is a RHP, LHP, high arm slot, ¾ arm slot, side arm, submarine, holds the ball for 2 seams, 4 seams, 1 seam, it doesn’t matter, the pitch definitions in this course apply to them all the same because they are based only on the shape of the trajectory of the ball.

New Way of Detecting & Defining Pitches

This course defines each distinct pitch type independent of the specific pitcher or the pitcher method, in a way that can be detected when only using ball tracking data. It also avoids the current ambiguity in pitch names, subjective names of pitches, and intent or technique-based pitch names, as used today. The definitions of pitch types in this course can help greatly in analytics, amateur scouting, advance scouting, broadcasting, and player development.

Working with pitch tracking data it becomes quickly obvious that everyone has been avoiding the elephant in the room, that the pitch names assigned to a pitch in the data are often wrong or missing. That means that stats such as "Average Slider Velocity" for example, won’t be accurate because there may be curveballs, changeups, fastballs, etc. mixed in with the "Sliders". Also, for example, if the pitch is tagged a “Slider”, you’re not guaranteed that it is in fact a “Slider”. When examining the metrics for this “Slider”, you could be looking at the metrics for example, of a Changeup.

Up until now, everyone has been trying to classify pitches from the point of view of the Pitcher and speed. The method in this course classifies pitches from the point of view of the Batter and trajectory shape. Different points of view. 

This course defines each pitch type with data metrics and shows a visual of the pitch flight path from the batter’s point of view. There is no subjectiveness in the way they are defined, meaning everyone who looks at the pitch data will arrive at the same pitch type name using these formulas and definitions. The pitches are defined in terms of their trajectory shape, not their speed, and not how the pitcher intended to throw them. How the pitcher produced the trajectory shape, or intended to produce that shape, are irrelevant for classification because from a Batter’s point of view, the Batter only knows the pitch shape that was produced.

This course doesn't write about how to throw these pitches, as there will be many ways to throw the same pitch shape, and besides, that’s not the purpose of this course. In fact, linking the method or intent for how to throw a pitch type is partly what has caused the current ambiguity and subjectiveness of calling pitches today..

What the Pros are saying

Scott Emerson - Oakland A's MLB Pitching Coach

I am very much a baseball information seeker. I want information from the physical, mental and data aspects. Using all 3 aspects are needed, as you need to use the different ways to look at things. When it comes to what’s being called as the strike zone , or advanced ball tracking metrics and pitch classification, Wayne Boyle and Pitchgrader are giving you advanced ways to use the information you need to make good decisions. The courses provide you with the skills to evaluate data information and will help you or your player try to reach your potential. Again , I look forward to what Wayne does next.

Miguel Bonilla - NY Mets Pitching Coach

As a pitching coach with more than 30 years of experience in professional baseball, I found the information in these courses useful because it allows me not to rely on my eyes and experience alone and gives me a data driven vocabulary I can use with my players when explaining the things I see in their performance.

Carlos Chavez - San Diego Padres Pitching Coach

Wayne, Awesome job with Pitchgrader and the courses! Great info and tremendous work you put together! Will recommend to anybody willing to get better!

Tim Doherty - Washington Nationals Hitting Coach

The Pitchgrader courses are an absolute must take. They detail state of the art metrics and analytics in a way that makes it easier to apply them and maximize their effectiveness. With where the game of baseball is today and the analytics and metrics that are being used by every team, I highly recommend enrolling in these courses to keep up. Wayne has done a phenomenal job with such informative courses.

Dustin Glant - Indiana University Pitching Coach

former Yankees AAA pitching coach

“The Fundamentals of Ball Tracking Metrics" course from PitchGrader is an essential development tool for any coach or player that is looking to better understand the basics of ball tracking technologies and that factors that influence pitch movement. With this gained understanding of Magnus force, pitch shape, spin tilt, and approach angles for the various pitches, a coach or player can have a better roadmap for where their pitches currently stand and what changes can be made for optimal success. Understanding PitchGrader’s "Modern pitch classifications", as an alternative to the basic pitch classifications used today, will allow for a deeper understanding for the nuances that exist within each pitch type. This deeper understanding for the metrics that define each pitch type allows for better informed decisions to be made in terms of pitch design and sequences for each players pitch packages.

Gil Patterson - Oakland A's Pitching Coordinator

I’ve had a chance to take the courses from Pitchgrader and I am fascinated with their potential. Pitchgrader’s Pro level baseball pitch analysis and pitcher profiling might completely change the way a coach approaches making adjustments to a pitcher’s repertoire. The 3D analysis, charts, graphs, heat maps, and many other evaluation examples provide a vast perspective, but fast actionable meaning for game review, opponent scouting, and game planning, while still allowing you to separate result from process for a deeper connection between the use of data and the goal of winning.
