Shane Greene on His (Hard-to-Classify) Repertoire
Last year, Eno Sarris wrote that Shane Greene “features a cutter and a slider, but where one begins and the other ends is tough to decide.” Sarris concluded his article by opining that the Detroit Tigers right-hander “has four breaking balls.”
PITCHf/x shows something different. They don’t have the 28-year-old reliever throwing a cutter at all. What they have is a combination of sliders and curveballs, with a notable flip-flopping of usage. Per PITCHf/x, Greene threw 46.6% sliders and 7.9% curveballs last year. This season, the pitch-tracking algorithm has him at 13.3% sliders and 30.1% curveballs.
And then there’s his heater. Greene has been two-seam heavy since moving to the bullpen last year, but while PITCHf/x has him throwing just 1.8% four-seamers this season, the system indicates he threw 19.6% four-seams (versus 25.2% two-seams) in 2016.
Intrigued by these conundrums, I went directly to the source. Greene, who has a 1.71 ERA and a 10.2 strikeout rate per nine innings over 33 appearances, broke down his repertoire when the Tigers visited Fenway Park last weekend.

Greene on his repertoire: “The pitch that’s 88 to 91 [mph] and is moving like a slider, I call it a cutter. I call it that because when I earned the pitch, I already had something I called a slider. It’s harder, so I try to use it more as a cutter — not so much as a swing-and-miss pitch, but to miss barrels with. And sometimes it gets big, and sometimes it stays smaller.
“The pitch that is 82 to 84-ish, sometimes 85, is what I call my slider. A lot of people think it’s a curveball, but that’s been my slider since I was in high school. Same pitch.
