Sometimes, a pitcher throws an off-speed pitch so well that you're led to question whether or not it's even possible for a ball to move the way it just did. Chicago White Sox fans are in luck, as 2019 All-Star Lucas Giolito has given them treat by describing the art and science behind his changeup in a recent interview with Rob Friedman, a.k.a. "Pitching Ninja."
Giolito will surely be Chicago's staff ace if/when the 2020 MLB Season gets started. In 2018, Giolito disappointed with a 6.13 ERA in his first full season in the bigs. That number was almost halved to a 3.41 ERA with a huge turnaround in 2019.
That leap was largely due to an increase in use and accuracy of his changeup.
It's a gift for White Sox fans to peek behind the curtain and see how Giolito works his magic. By releasing the pitch like it's a fastball and letting the ball hang more, he leaves batters whiffing and wondering what hit them.
Looking at his fastball and changeup side by side, there's not a lot of differences between the two as they approach the plate. That similarity make it difficult for batters to discern what's coming at them, leading to plenty of sneaky strikes.
