Brooks Raley on Being a Pitching Nerd

Brooks Raley has been an effective reliever since returning to MLB in 2020 after five seasons as a starter with the KBO’s Lotte Giants. He’s been especially good for the past two. Taking the mound for the Tampa Bay Rays in 2021 and for the New York Mets this past season, the 35-year-old left-hander has logged a combined 2.74 ERA and a 3.21 FIP over 126 relief appearances. Moreover, he’s allowed just 81 hits and fanned 122 batters in 108.1 innings. Working primarily in a setup role, he’s been credited with a pair of wins and nine saves.
Raley is also a bona fide pitching nerd. That wasn’t the case when he got cups of coffee with the Chicago Cubs in 2012 and ’13, but then came a career-altering adoption of analytics when he was overseas. Looking to optimize his talents, the Texas A&M University product schooled himself on how his pitches played best, and what he could add, subtract or tweak in order to attack hitters more effectively. The result was a successful return to the big leagues, and not only has he put up a good FIP and a solid SIERA, but he also knows exactly what those acronyms mean.
Raley discussed his analytics-influenced evolution as a pitcher when the Mets visited Fenway Park this summer.

David Laurila: You played five years in Korea. What was that experience like?
Brooks Raley: “I loved it. I learned a lot. We’re talking analytics, and I went over there not very polished. I was a starter but didn’t have a changeup or a cutter, so I started watching YouTube videos of all the different shapes, spin rates, tilts, extension — all that stuff. For a little bit, I tried to throw like Chris Sale. I kind of leaned over and tried to create some different angles and see what kind of shapes I could get. I really got into that side of the sport. I found my cutter, found my arm slot, and then the sinker got better. My slider also got better. That all happened when I was in Korea. It’s how I got back [to MLB].”
Laurila: Why hadn’t you gotten into analytics and begun making changes prior to going to the KBO?
Raley: “I wouldn’t change anything about my career, but coming across analytics and what defines your strengths better… when I was coming through the minors, it was ‘sinkers down and away are safe’ and ‘ground balls over strikeouts.’ But I actually and naturally pitch better inside. That’s to both sides. To righties, I throw the cutter and the slider and have the changeup and sinker to keep them honest. To lefties, I’ve got the running sinker. It’s been inconsistent this year, I can’t really figure that out, but it’s been between 14 to 19 horizontal and probably anywhere from eight to two vertical. It’s kind of a unique pitch because it spins 2,400 [RPMs] or so. It’s got some life and late dart to it.
“I always struggled with changeups before I went over there, because I’d always try to throw the 10 miles an hour off [from the fastball]. Now I throw a Viulcan change, so I don’t really kill spin but I put it on the horizontal axis. I get around 19 and I’m either on the line or under the line. Basically, I found some unique shapes to really broaden my left and right, because I can throw a slider at 22 inches of horizontal and a changeup at 20 [in the opposite direction].” Read the rest of this entry »
