Austin Adams Is Slider-Reliant and Learning To Leverage Seams

Austin Adams threw a higher percentage of sliders than any pitcher in baseball last season. In 56 relief outings comprising 41 1/3 innings, the 33-year-old right-hander relied on his signature offering 73.8% of the time. The heavy usage wasn’t an outlier for Adams. Since breaking into the big leagues in 2017, his 77.2% slider percentage is tops among hurlers to throw at least 100 innings.
His overall numbers have been solid. Pitching for five teams, including the Athletics last year, Adams has a 4.10 ERA, a 3.98 FIP, and a 31.6% strikeout rate over 155 2/3 career innings. He’s challenging to square up consistently, and he’s held opposing batters to a .199 batting average. Command has been the fly in the ointment, and not just because of his higher-than-ideal 13.9% walk rate. Adams plunked 13 batters last season, and in 2021 with the Padres, he outlandishly logged 24 HBPs in 52 2/3 frames.
Now in big league camp with the Red Sox after signing a minor league deal in January, Adams sat down to talk about his slider(s) at Boston’s spring training facility in Fort Myers.

David Laurila: You throw a ton of sliders. Why?
Austin Adams: “The reason I throw so many sliders is because I enjoy having a job in baseball. It’s my best pitch. I try to take each one of my pitches, individually, in a vacuum. For me, it’s not necessarily about setting things up. I’m not saying that’s not a thing. What I’m saying is that it’s harder to quantify. My highest-graded pitch is my slider — metrically it’s a really good pitch — so I’m going to throw it the majority of the time. It’s what gives me the best opportunity to get outs.”
