Brandon Woodruff Has Leveled Up His Changeup

Brandon Woodruff has been good for years now, but he’s always flown a bit under the radar. In some ways, he can thank his rotation-mates for that: Corbin Burnes has overshadowed him with his ascension to ace status, and Eric Lauer and Freddy Peralta have taken big steps forward of their own. The lack of attention directed Woodruff’s way might also have something to do with him being a little boring. He’s been a polished pitcher with a diverse arsenal since his major league debut in 2017, and nothing has really changed about him since he broke out as a full-time starter in ’19; his performance, velocity, mechanics, and arsenal have all remained consistent. And while having the seventh-best ERA- and fifth-best FIP- in baseball since 2019 unequivocally makes him a great pitcher, he doesn’t seem to have been as big a part of the “best pitcher in baseball” conversations that happen around hypothetical water coolers as those numbers might suggest.
His start to 2022 isn’t helping him much in that regard, with a 5.18 ERA through five outings, though there’s some small-sample funkiness behind that number. Woodruff’s BABIP is 25 points higher than his career average, his LOB rate is an unsustainably low 60%, and his ERA estimators are all around where they typically have been (2.83 FIP/3.25 xFIP/3.07 xERA). I’m not worried about his long-term performance, and regardless, that’s not what this article is about. Instead, I want to focus on Woodruff’s changeup, a pitch that has been anything but boring this season and that was on full display in his most recent start against the Reds:
Most of the talk surrounding Woodruff focuses on his pair of elite, high-velocity, whiff-inducing fastballs, which he throws over 60% of the time. Otherwise, he mixes in a curve and a slider that have both served him well, even if they’ve never quite reached the level of his heaters. Woodruff’s changeup, though, has started to become a serious weapon:
| Year | Sample | Usage | SwStr% | GB% | wCH/C | wOBA |
|---|---|---|---|---|---|---|
| 2019 | 280 | 14.2% | 15.4% | 41.7% | -1.15 | .359 |
| 2020 | 213 | 17.6% | 15.0% | 59.0% | -0.46 | .260 |
| 2021 | 400 | 14.2% | 21.5% | 40.6% | 1.09 | .229 |
| 2022 | 82 | 17.7% | 30.5% | 71.4% | 1.22 | .182 |
