Devin Williams and the Unicorn Changeup
The inspiration for a new pitch design can strike at any moment. Usually, it’s a coach or a teammate sharing their well-earned wisdom or tricks-of-the-trade. Sometimes a new pitch is developed during bullpen sessions as a pitcher tinkers with a new grip or finger placement. More recently, pitch design has been outsourced to technologically advanced pitching labs like Driveline, where pitchers try to harness all the data at their disposal to create the most effective pitch possible. But for Devin Williams, the design for his changeup didn’t come from any of the normal avenues. Instead, it was developed on the neighborhood fields of his childhood.
In a recent media session, he described how he had thrown a version of what is now his changeup since he was growing up:
“I started throwing like that as a kid. Like, when I played catch with my friends, just to mess with people, trying to make them miss the ball when I threw it to them. That’s what turned into my changeup. I’ve had that since I was maybe 10 years old.”
Changeups come in a variety of types and styles. There’s the classic change that relies on a high velocity differential off the fastball to create deception. The circle change adds tumbling vertical movement to further differentiate the pitch from a heater. Felix Hernandez’s cambio redefined what a modern changeup could look like without the trademark velocity differential. Williams’ changeup is an entirely different beast, making it a changeup unique in baseball — the unicorn changeup. Read the rest of this entry »
