The Incomparable Adam Wainwright
I’ll forgive you if you thought Adam Wainwright was cooked in 2018. He landed on the IL after three middling starts (12 strikeouts in 15.2 innings, a 3.45 ERA and 5.20 FIP), made a single short start in May, then didn’t pitch again until September. His sinker had never been slower; his curveball had never had less bite. At 37, that’s a scary combination, and it hadn’t come out of nowhere; he posted an ERA of 5.11 in his previous season, along with career-worst marks in K%, BB%, and FIP.
Three years later, Wainwright is a down-ballot Cy Young candidate. He’s accrued as much WAR as the next five Cardinals starters combined. St. Louis probably won’t make the playoffs, but it won’t be because of the once and current ace, a timeless wonder having his best season since before tearing his Achilles in 2015. How has he done it? I’m glad you asked.
Major leaguers are so good these days, on both the pitching and hitting side. Batters have never hit the ball harder on contact or tried so hard to hit home runs. It’s scary out there for a pitcher; any contact could leave the park at the drop of a hat. Pitchers have compensated in the obvious way: throwing pitches that avoid contact. Swinging-strike rate and strikeout rate are both marching inexorably higher, with occasional step changes (the sticky stuff crackdown, for example) fighting the tide.
Wainwright doesn’t have that option, though. If you asked him candidly, I’m sure he’d love to throw 95 mph and snap off sliders that turn into Pitching Ninja GIFs. But that was never his game, and he wasn’t going to suddenly turn into that kind of pitcher at age 39. In fact, when Wainwright began to decline, that was the common diagnosis. An aging sinker-first pitcher in the age of four-seamers? Sounds like a recipe for failure.
That’s all true! Wainwright’s sinker virtually never induces an empty swing. That’s not even a new thing; he’s only had one year in his entire career with a swinging-strike rate above 5% on the pitch. He’s only had a whiff rate higher than 10% in two of his 14 seasons. When batters take a cut, they mostly hit the ball.
