Sunday Notes: Orion Kerkering Studies for a Doctorate in Sliders
Orion Kerkering enjoyed a meteoric rise to the big leagues last year. The 2022 fifth-round draft pick began the campaign in Low-A Clearwater, and when
October rolled around he was taking the mound for the Philadelphia Phillies in the postseason. His numbers along the way were eye-catching. Pitching out of the bullpen at four minor-league levels, the University of South Florida product logged a 1.51 ERA and a 38.9% strikeout rate over 53-and-two-thirds innings. Called up in late September, he proceeded to fan six batters and allow one run in three appearances comprising the same number of innings.
That Kerkering was then entrusted to take the ball in the playoffs was a testament to his talent — a big part of which is a bat-missing offering even more impressive than his 98.6-mph fastball.
“That’s hard for me to do,” Kerkering replied when asked to describe his signature pitch. “I call it a slider and everyone says it’s one of the best ones out there. To that, I’m kind of, ‘OK, whatever. That’s fine.’ I just trust it as much as I can.”
The 22-year-old right-hander started throwing a slider as a Venice, Florida prep. Velocity-wise, it was 78-81 mph early on, and from there it got “faster and faster” to where it is now a crisp 86-87. The shape is basically the same — “with maybe a little more movement” — as is the grip.
“It’s kind of like how you teach a 12-year-old a curveball,” he said of the grip. “But instead of spinning on top of it, I spin on the 1:20-2:00 o’clock axis. If you think of [Clayton] Kershaw’s curveball, it will spin and then drop. Mine is the same way. It has the gyro spin, then it takes off.” Read the rest of this entry »
