When you bear in mind my writing earlier this season about Brent Honeywell Jr.’s changeup-screwball combo or Hurston Waldrep’s splitter, you may most likely think about how a lot I like a weird-ass changeup-like factor. A lot so I’m beginning to marvel if it is likely to be value it to ask Meg for a “Bizarre-Ass Changeup World Tour” tag within the CMS.
Till then, think about Logan Allen. No, the opposite Logan Allen. The one who got here again up from the minors to interchange Shane Bieber in Cleveland’s rotation and fully barbecued the Pirates on Tuesday night time. Critically: 5 innings, no runs, one hit, one stroll, eight strikeouts. That’s some heavy stuff.
The important thing to Allen’s complete shtick is his changeup, which is in contrast to another pitch in baseball. It’s gradual, even by the requirements of a pitch that’s outlined by its slowness: simply 82.9 mph on common, although since he doesn’t throw very laborious by trendy requirements, that’s not as excessive a quantity because it appears on first look. What’s excessive is the best way the pitch strikes.
Baseball Savant likes to match pitch motion to choices inside a sure velocity band. A pitch with the identical title may need totally different traits primarily based on how laborious it’s thrown, and a pitch that’s thrown at a better velocity is within the air longer than a slower pitch. Meaning it’s going to drop extra, as gravity has extra time to behave on it. However let’s simply take a look at motion in absolute phrases: What number of inches does Allen’s changeup drop, and the way a lot does it transfer laterally?
See, that’s the opposite factor that defines a changeup, or makes it distinct from a breaking ball at any charge. Breaking balls transfer throughout from the pitcher’s arm facet to the glove facet, and changeups fade to the arm facet. This makes the changeup a useful weapon in opposition to opposite-handed hitters; by extension, it’s vital for a left-handed beginning pitcher like Allen.
The pitcher with essentially the most arm-side motion on his changeup is Devin Williams, writer of the airbender, which is mainly a screwball. The airbender will get 20.3 inches of arm-side motion, or 30% extra break than common. After Williams comes a cohort of 259 different pitchers, each single considered one of whom throws a changeup with no less than 6.7 inches of arm-side motion.
Then there’s Allen. After I pulled up the plot of each pitcher’s changeup motion, Allen was up to now off to the facet that I put my cursor over his dot and stated, “this one goes wee, wee, wee, all the best way house.” He will get a mean of 1.8 inches of horizontal motion on his changeup, which is 12.4 inches — a full foot — lower than is to be anticipated. His changeup is so bizarre it defies the very which means of what a changeup is. And that determine, 1.8 inches of arm-side motion, is simply a mean. A couple of quarter of Allen’s changeups this season have both had impartial motion or damaged towards the glove facet. Cease! You’re going the mistaken manner!
To date this season, Statcast has recorded 101 changeups with both impartial or glove-side motion. Allen is accountable for 79 of these. No different pitcher has greater than 4. The bizarre motion sample (or lack thereof) to his changeup has led to some confusion over what the pitch really is — a changeup or a splitter? But when it had been a splitter, the low velocity can be much more of an outlier, and the dearth of arm-side motion simply as mystifying.
You realize what doesn’t assist with the confusion? Whenever you google “Logan Allen changeup grip,” one of many high outcomes is an article from our personal David Laurila, with a close-up picture of Logan Allen demonstrating a Vulcan change grip. The one drawback: It’s the mistaken Logan Allen. Our Logan Allen denies throwing a splitter of any sort and holds his changeup with a extra frequent circle grip. (How did these guys not provide you with nicknames to keep away from this sort of confusion? They had been in the identical group for some time, for God’s sake!)
That makes even much less sense; lots of of pitchers throw a circle change, and it runs to the arm facet prefer it’s imagined to. The airbender, which might be the changeup that resembles Allen’s least in the whole world, is mainly thrown off a circle change grip. So what makes Allen’s so bizarre?
Right here’s Williams. Discover him pronating his wrist as he releases the ball, virtually yanking the ball down along with his fingers as he lets it go. The ball spins counterclockwise and strikes from left to proper, from Williams’ perspective.

Allen pronates his wrist too, however later within the supply. On the level of his launch, it virtually appears like he’s placing backspin on the ball. A distinct spin axis means a distinct course of motion — or on this case, a visit straight down.

The opposite main distinction is that Williams is considered one of three pitchers to common greater than 2,500 rpm on his changeup, however Allen is considered one of 4 pitchers to common much less than 1,000 rpm. As I discussed within the Waldrep article, excessive low spin on a changeup results in an unstable, virtually knuckleball-like flight sample.
So why does Allen’s work? Effectively, within the context of the remainder of his repertoire, it’s virtually just like the changeup is fading again to his arm facet in spite of everything. Allen is a relatively quick (6-foot) pitcher who throws from a low arm slot, a bit shy of three-quarters. (Let’s name it a seven-twelfths arm slot.) He pulls all the things throughout his physique. His different three pitches are a four-seamer that’s additionally close to the underside of the league when it comes to arm-side motion, a cutter with above-average glove-side horizontal motion, and an enormous, gradual sweeper with large horizontal break. Our man simply doesn’t just like the left facet of the X-axis. So compared to the cutter and the sweeper, possibly the changeup does appear to be it’s fading in spite of everything.
My different principle is that it’s so bizarre hitters don’t know what to do with it. We’ve all seen pitchers get away with backup breaking balls earlier than. These are sliders, normally, that come out of the oven fully underspun. And sometimes as not, the hitter reacts to such a pitch with full psychological vapor lock, as if he anticipated to come across a baseball however partway by way of his load, the ball modified to a paper airplane. Typically the hitter is unperturbed, reads the ball accurately, and hits it 400 ft. In that case, the backup breaking ball is named a “cement mixer,” and it’s a nasty factor.
ESPN colour analyst Kyle Peterson, who covers largely school baseball and due to this fact has seen extra crappy breaking pitches than you or I’ll witness in 10 lifetimes, goes on every so often about how if a pitcher had been one way or the other capable of systematize the backup breaking ball — to throw it persistently reasonably than encounter it as a random error — he’d be unhittable, as a result of batters would haven’t any clue what to do with it. I’m questioning if that’s what Allen has carried out right here. He’s persistently throwing this distinctive, slow-rotating turducken of a pitch, and it’s freaking opposing hitters out. Of his 4 pitches, the changeup has the best whiff charge and lowest opponent wOBA and xwOBA. It is likely to be a weird-ass changeup, however it’s working.
