Alex Lange was asked about his breaking ball on a Zoom call yesterday, and the more he said about it, the more I wanted to know. Initially, the fast-rising, 25-year-old Detroit Tigers prospect told the small cadre of reporters that he doesn’t consider the pitch a slider, as it’s often categorized. Rather, he considers it a curveball “because of the spin axis.” Lange added a few details, albeit without getting especially nerdy.
I asked Lange — a likely Top 10 in our forthcoming 2021 Tigers Top Prospect rankings — if he’d like to nerd-out on the plus offering. He was happy to oblige.
“Analytically, you look at the pitch and it’s not very good,” said Lange, who was drafted 30th overall by the Chicago Cubs in 2017 and subsequently dealt to Detroit two years later as part of the Nick Castellanos deal. “The spin efficiency is anywhere from 45% to 55%, and when you think of a breaking ball, or a curveball, you’re like, ‘Nah, that’s not very good.’ The depth on it is negative-10 to negative-12 inches of vertical break, so you’re like, ’Nah, it’s not very good.’ But when it’s thrown hard with the spin axis being as close to six as it gets sometimes, that’s where we’re getting the swings-and-misses and takes on it. That’s because you’re not seeing the dot. You’re seeing the ball rotate just like my four-seam rotates, but in the opposite direction. And it’s hard, and it’s late. I think that’s why it’s effective. I just try to stay on top of it, rip it straight down, and get 12-to-six action on it, and try to pair it with the heater.”
As expansive as that answer was, followups were order. I asked the right-hander about the spin rate on his curveball. Read the rest of this entry »
