PITTSBURGH – Our PitchTracker Metric Analysis Series featuring Dr. Buddy Clark, Diamond Kinetics co-founder and Professor of Mechanical Engineering at the University of Pittsburgh, and former University of Cincinnati and Lincoln Memorial University catcher Russell Clark continues with Spin Direction.
Throughout this series we will tell you what each metric is, why we measure that particular metric and why you should care about utilizing and understanding the metric, as it applies to your pitching motion.

PitchTracker Metric Analysis: Spin Direction
What Is It
Spin Direction is defined as the direction of motion of the leading edge of the ball – the direction of the ball’s spin after release as it travels to the plate.

Spin Direction App Display
To quantify spin direction, a spinning arrow is shown around a baseball inside a clock face
The spin direction points to the time nearest to the spinning arrow as it comes into view from the leading edge of the ball pic.twitter.com/czZU3vfmiF

"What players often see … is their pitch doesn't break in the way the 'classic pitch' says it would."
A look at how arm slot (and other variables) can impact the spin direction on your fastballs and curveballs.
