Sunday Notes: Jacob Misiorowski Throws a Sinker-Like Changeup… Only Sometimes
Jacob Misiorowski has a fastball that consistently reaches triple digits, and he augments it with an effective curveball-slider combination. Usage-wise, the 24-year-old Milwaukee Brewers right-hander is throwing his high-octane heater at a 62.3% clip, while his breaking-ball percentages are 16.6 and 17.3 respectively. Given the lethality of those pitches — his xBA is a paltry .168, and his K-rate an MLB-best 41.8% — he has little need for a changeup…
… but there is one in his arsenal. From time to time, he will even show it to a batter. Of the 289 pitches Misiorowski has delivered so far this season, 11 (3.8%) have been changeups. The story behind his only-sporadically-used weapon?
“I’ve had a changeup my whole career,” Misiorowski told me prior to throwing three of them in a 101-pitch start at Fenway Park on Tuesday. “That was one of the first pitches I truly learned. But then as I started throwing harder, I began going away from it, and it obviously got worse and worse the less I threw it. By the time I got drafted [63rd overall in 2022], I basically didn’t have a changeup any more. I had to relearn it, re-figure it out. So, yeah, it’s always been there, but it hasn’t always been there.”
Misiorowski went on to tell me the grip was originally a more conventional four-seam circle, but that he now has his pointer and middle fingers together, and his thumb underneath. He also said that he likes the amount of horizontal he gets on it, which is generally around 18 inches and has been up to 20. When I told him that the movement profile sounds a little like a two-seam sinker, he agreed that it does.
A few more things Misiorowski told me about the pitch are unfortunately lost, due to glitches I’ve recently encountered on my iPhone’s recording app (I mentioned this teeth-gnashing, hopefully-resolved-soon, issue in Monday’s piece on Padres’ broadcaster Mark Grant.) Fortunately, I was able to grab a few minutes with Brewers pitching coach Chris Hook, who made up for the missing words with his own perspective.
How would he describe Misiorowski’s changeup? Read the rest of this entry »
