Batters Can’t Stand A.J. Minter’s One Simple Trick

Even if you aren’t a Braves fan, you probably have a general idea of how their season is going so far. Max Fried? He’s still good, and still the ace for the defending world champions. Kyle Wright has taken a step forward and Charlie Morton has taken a step back. The hitters? You pretty much know them all; Dansby Swanson, Austin Riley, Ronald Acuña Jr., and Matt Olson lead the offense this year.
If you’re paying the barest bit of attention, you’d already know all of those names. They either starred in last year’s postseason, made headlines in a big offseason trade, or starred early in this season. When you get to the bullpen, though, you might be lost. Remember that stalwart relief crew from the playoffs? Will Smith has been abysmal, half a win below replacement level. Tyler Matzek has an ERA above 5, a FIP above 5, and an xFIP above 6. Luke Jackson hasn’t even pitched this year; he tore his UCL before the season and will miss the entire year.
Some of that slack has been picked up by new names. Kenley Jansen has been solid. Spencer Strider is electric, though he’s now a starter — nice problem to have. But the fourth member of last year’s bullpen quartet, A.J. Minter, is making up for the rest of his cohort’s absence. He’s off to the best start of his career, and one of the best starts of any reliever in baseball.
In some ways, Minter is like a lot of other relievers you’ve seen. His best pitch is a high-spin, high-velocity fastball. He backs it up with a breaking pitch that’s somewhere between cutter and slider, 90 mph with a touch of horizontal break. To keep righties honest, he also has a hard changeup. There are a lot of relievers who fit that general mold, and until this year, you might have easily lost Minter in the crowd.
Why bring him up, then? Surely, he’s just on a good streak, a few weeks and home runs away from just being another plus reliever instead of an unsolvable hitting riddle with an ERA around 1. Maybe that’s true. Maybe this is as good as Minter will ever be — and to be clear, it’s as good as most pitchers will ever be. But I’m interested in something else:
Year | Zone% | BB% |
---|---|---|
2018 | 43.5% | 8.5% |
2019 | 39.6% | 15.6% |
2020 | 42.3% | 10.6% |
2021 | 44.9% | 9.0% |
2022 | 37.2% | 4.4% |
Yes, Minter is throwing fewer pitches in the strike zone than ever. He’s also walking batters at a career-low rate (excluding a 15-inning cameo in 2017 that I’m leaving off my charts). That makes about as much sense as clicking on a pop-up ad, but let’s see if we can disentangle what’s going on here.
