How’s That New Cutter Treating You?

Do you remember the springtime? We were so young and carefree, so full of hope. We hadn’t even breathed in our first lungfuls of Canadian wildfire smoke. Pitchers were full of hope, too. They’d spent the whole offseason in a lab, or playing winter ball, or maybe just in a nice condo, trying to figure how to get better.
Amazingly, a lot of them settled on the exact same recipe for success: start throwing a cutter. You couldn’t open up a soon-to-be-shuttered sports section without reading an article about some pitcher whose plan for world domination hinged on whipping up a delicious new cut fastball. Now that we’re in the dog days of summer, it’s time to check and see how those cutters are coming along. Are they browning nicely and just starting to set? Or have they filled the house with smoke, bubbling over the sides of the pan and burning down to a carbonized blob that needs to be scraped off the bottom of the oven with steel wool?
I pulled data on every pitcher who has thrown at least 400 pitches in both 2022 and ’23, focusing on the ones who are throwing a cutter at least 10% of the time this year after throwing it either infrequently or not at all last season. These cutoffs did mean that we missed some interesting players like Brayan Bello and Danny Coulombe, but we’re left with a list of 25 pitchers.
So did their new toys turn them into peak Pedro? The short answer is no. Taken as a whole, they’ve performed roughly as well as they did last season. As you’d expect from any sample, roughly half our pitchers got better, and half got worse. Of the pitchers who improved from last year to this year, I don’t think I can definitively say that any of them reached new heights specifically because of the cutter.
