Clarke Schmidt Throws a Baby Whirly

Clarke Schmidt has added an important weapon to his arsenal since he was first featured here at FanGraphs in January 2021. Given the organization he plays for, it isn’t much of a surprise that that addition is a sweeping slider — or, in New York Yankees vernacular, a “whirly.” The 26-year-old right-hander is throwing his version of the pitch 37.2% of the time this season, and with great success: Opposing hitters are batting just .148 against the offering, with a .164 SLG and a .186 wOBA.
His overall numbers are likewise impressive. The 2017 first-round pick has made 23 appearances this year — all but three out the bullpen — and boasts a 2.82 ERA and a 3.17 FIP. He’s allowed 41 hits and fanned 51 batters in the same number of innings.
Schmidt discussed his “baby whirly” when the Yankees visited Fenway Park earlier this month.

My usage has been high, and I’ve had some really good results with it. Beyond that, I’ve cleaned up some things — some arm path stuff — and there has probably been more maturity in my pitch selection. But I’d say that the slider has been the number one change.”
Laurila: I recall you saying in January 2021 that some people considered your curveball more of a slider.
Schmidt: “For sure. I’ve always had a big breaking ball, but it’s hard — it’s 84-85 [mph] — so even though people are throwing harder curveballs now, it does get considered a slider sometimes. But now that I’m throwing both, there are distinct differences. I have two different shapes. Read the rest of this entry »
