Sunday Notes: Verticality in Mind, Casey Mize Has Designs on Being Better
Casey Mize plans to be a different pitcher in 2021. Not just in terms of results — the rookie right-hander had a 6.99 ERA and a 6.47 FIP in seven starts with the Detroit Tigers last year — but also with how he employs his arsenal. Not surprisingly, data will be playing a role. Mize has a history with pitch design that dates back to his days at Auburn, and those efforts have only increased in pro ball.
I asked the first-overall pick in the 2018 draft what technology has taught him about his pitches, and how it’s shaping his efforts to improve.
“It’s pretty much a horizontal profile,” Mize responded. “We’re starting to take the four-seamer up a little bit to add a little more vertical, because it played so well last year. My splitter is super vertical, and we’re trying to really maximize that, because my slider has more of a horizontal break.”
Mize acknowledged that his two-seamer profiles as horizontal as well, getting more arm-side run than depth. It’s a pitch he’s favored, but that’s one of the changes currently in the works.
