Cade Horton's Spin is Like a Magnet, But His Movement Covers the Whole Compass

The moment when Cade Horton's potential first jumped up a level came last year with Triple-A Iowa, when he first began to find the changeup he now sports in the majors. Even by his own reckoning, though, the pivotal moment for him came when he found that he could trust that pitch against big-league bats, last month in Miami.

"I thought it was in a good place in Triple A, and then got here, and it was really the Miami start where I got a good feel for it," Horton said earlier this month, during the Cubs' trip to Minnesota. "From there, it's just kind of taken off, to where I'm able to repeat that pitch. It's been huge for me."

Since then, that pitch has been a staple in Horton's arsenal to lefties, and it hasn't stopped dominating opposing batters. On the contrary: an eye-popping 59.6% of swings at the pitch have come up empty. The changeup was virtually non-existent when the Cubs drafted Horton in the first round of the 2022 MLB Draft, but now, it's a vital weapon. Did that change how he has to think about himself as a pitcher, and how he operates?

"Not necessarily. I think it's more, I just use the changeup more to lefties," he said. Indeed, 112 of the 116 he's thrown in the majors have been to left-handed batters; he's not (yet) the type of hurler who will go to the changeup right-on-right. "So that's been the big key, is being able to have that pitch that runs away from them. That opens up fastballs in and fastballs away. The slider's more for righties, and that's why I've been working on the sinker and trying to set up the pitch away from them."

In other words, Horton prefers to use his fledgling sinker to attack righties inside, setting up the slider. The changeup, coming from his high three-quarters slot and with his natural tendency to supinate (the direction of forearm movement that better facilitates breaking balls, rather than arm-side movement), has more run than tumble, which makes it the type of change that's harder to throw with conviction to same-handed batters.

As Horton alluded to, his slider (Statcast, as shown above, labels most of those as sweepers, but the ones labeled sweeper and slider are both what Horton calls his slider) is the go-to pitch against righties. However, he's not kidding around when it comes to making the sinker a meaningful part of his arsenal to them. In two starts this month, the sinker has emerged as a key third pitch to righties, with his fastball becoming less predominant.

He's had to do that, of course, because his fastball isn't a traditional four-seamer at all. It's much closer to being a power cutter—and indeed, some classification systems call it one. Horton didn't set out to create this type of heater, but now that he has one, he understands the value of steering the sinker in on righties to set up both the fastball and the slider away.

"I think it just naturally happened," Horton said of his change in fastball shape, which happened after the Cubs selected and signed him but isn't the product of conscious pitch design. "Just getting around the ball more and creating that cut action—which I don't think is a bad thing. I think it plays against lefties, and then it runs off the barrel to righties."

The fascinating thing is that, now that he has the changeup (and his curveball, which stands in for the slider against lefties), he offers three different looks to hitters of each type—but they all come from one basic spin axis. Horton's changeup, sinker and slider each rely on considerable seam-shifted wake. They start on similar spin-based movement paths as his four-seamer and curve, but are deflected based on the orientation of the seams and the action of the air on the ball.

The chart above shows, on the left, initial spin direction, meaning what the pitcher actually imparts on the ball. Bars at the top of the clock graphic indicate the frequency of pitches thrown with backspin, which will "rise" (drop less than gravity would normally dictate) en route to the plate. Bars at the bottom show the frequency of pitches with topspin, like a true overhand curveball. Bars on the nine o'clock side show the frequency of pitches whose spin would push them toward the first-base side of the plate, away from a righty batter; bars on the three o'clock side show the frequency of those with spin pushing them toward a righty batter.

On the right, instead of spin direction, we see the actual movement direction of pitches. The difference between the two is explained by seam effects. Notice how, on the left, Horton's pitches cluster mostly around the 12:30 and 7:30 parts of the clock. That means that it's relatively hard for hitters to distinguish even between, say, his four-seamer and his slider, because they enjoy "spin mirroring"—the ball is spinning along very close to the same axis, so even though the directions of spin on the two offerings are opposites, it's hard to see the difference. A change in spin axis can make a visual difference for a batter, but telling which direction a ball is spinning along a similar axis is very hard.

Compounding that difficulty, though, is that Horton also has pitches that diverge from each other in ways spin can't explain. Thus, even for a lefty batter (who rarely sees the slider and only needs to worry about the curve), there are mutliple layers of trouble. He could be throwing the fastball or the curve, and spin mirroring would make it hard to tell which. He could also be throwing the changeup, and because it has a similar spin axis to the fastball (and a near-identical arm angle; Horton has worked hard to match release points on those two offerings) and the two pitches veer opposite directions due to release angle and seam effects, they end up in very different spots. That's how you miss bats with your changeup almost 60% of the time, without elite movement on the pitch.

The slider is an especially nasty version of the same problem, because for a righty, it's like dealing with the curveball problem and the changeup problem for lefties, rolled into one pitch. It's shielded by spin mirroring, especially now that he has the sinker working, but it also has the seam-effect sweep that mirrors the changeup's run. Unlike the changeup or the fastball shape, the slider has been like this since Horton was an amateur.

"It's kind of always been that way," he said. "I don't think too much about metrics. I think more about executing a pitch. I know where my slider works, and it's down and away, so it's just about executing to that spot."

That's really what it comes down to, for him. He's only gotten hurt in the majors when he's made mistakes over the heart of the plate. With that blooming movement spread from such a tricky set of spin orientations, he's one of the game's more deceptive hurlers, and he also happens to throw 96-98 with life on the fastball.

"It's just all about executing: Where are my misses? The hits I'm giving up, where are the fastballs?" he said. To him, the next step is simply to eliminate those, and to continue honing his feel for putting batters away with the heater. "Just execution. Two-strike execution is big, maybe getting to the top of the zone, making quality pitches."

Over time, if he can sharpen his command a bit, Horton could jump another level and become an ace by learning to use all of his pitches to both left- and right-handed batters in certain situations. For now, though, if he can avoid the worst of the missed locations he's had over his first two and a half months in the majors, he can be a solid mid-rotation starter on a playoff-bound Cubs team. For a rookie, that's plenty.
