Logan Allen Is Again within the Majors, and I’m a Little Freaked Out

Logan Allen

If you bear in mind my writing earlier this season about Brent Honeywell Jr.’s changeup-screwball combo or Hurston Waldrep’s splitter, you may in all probability think about how a lot I like a weird-ass changeup-like factor. So a lot so I’m beginning to surprise if it is perhaps price it to ask Meg for a “Weird-Ass Changeup World Tour” tag within the CMS.

Until then, contemplate Logan Allen. No, the opposite Logan Allen. The one who got here again up from the minors to exchange Shane Bieber in Cleveland’s rotation and utterly barbecued the Pirates on Tuesday night time. Seriously: Five innings, no runs, one hit, one stroll, eight strikeouts. That’s some heavy stuff.

The key to Allen’s entire shtick is his changeup, which is not like another pitch in baseball. It’s sluggish, 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 onerous by trendy requirements, that’s not as excessive a quantity because it appears on first look. What is excessive is the best way the pitch strikes.

Baseball Savant likes to check pitch motion to choices inside a sure velocity band. A pitch with the identical title might need completely different traits primarily based on how onerous it’s thrown, and a pitch that’s thrown at the next velocity is within the air longer than a slower pitch. That means it can drop extra, as gravity has extra time to behave on it. But let’s simply have a look at motion in absolute phrases: How many 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 price. Breaking balls transfer throughout from the pitcher’s arm aspect to the glove aspect, and changeups fade to the arm aspect. This makes the changeup a useful weapon towards opposite-handed hitters; by extension, it’s vital for a left-handed beginning pitcher like Allen.

The pitcher with probably 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 certainly one of whom throws a changeup with a minimum of 6.7 inches of arm-side motion.

Then there’s Allen. When I pulled up the plot of each pitcher’s changeup motion, Allen was to this point off to the aspect that I put my cursor over his dot and stated, “this one goes wee, wee, wee, all the way home.” He will get a median 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 median. About 1 / 4 of Allen’s changeups this season have both had impartial motion or damaged towards the glove aspect. Stop! You’re going the improper means!

So far this season, Statcast has recorded 101 changeups with both impartial or glove-side motion. Allen is liable 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 truly is — a changeup or a splitter? But if it had been a splitter, the low velocity could be much more of an outlier, and the shortage of arm-side motion simply as mystifying.

You know what doesn’t assist with the confusion? When you google “Logan Allen changeup grip,” one of many prime outcomes is an article from our personal David Laurila, with a close-up picture of Logan Allen demonstrating a Vulcan change grip. The solely downside: It’s the improper Logan Allen. Our Logan Allen denies throwing a splitter of any form 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; tons of of pitchers throw a circle change, and it runs to the arm aspect prefer it’s presupposed 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?

Here’s Williams. Notice him pronating his wrist as he releases the ball, virtually yanking the ball down together 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. At the purpose of his launch, it virtually appears like he’s placing backspin on the ball. A distinct spin axis means a distinct path of motion — or on this case, a visit straight down.

The different main distinction is that Williams is certainly one of three pitchers to common greater than 2,500 rpm on his changeup, however Allen is certainly 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? Well, within the context of the remainder of his repertoire, it’s virtually just like the changeup is fading again to his arm aspect 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 every part throughout his physique. His different three pitches are a four-seamer that’s additionally close to the underside of the league by way of arm-side motion, a cutter with above-average glove-side horizontal motion, and an enormous, sluggish sweeper with large horizontal break. Our man simply doesn’t just like the left aspect of the X-axis. So compared to the cutter and the sweeper, perhaps the changeup does appear like 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, often, that come out of the oven utterly underspun. And usually 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 means of his load, the ball modified to a paper airplane. Sometimes the hitter is unperturbed, reads the ball appropriately, and hits it 400 ft. In that case, the backup breaking ball is known as a “cement mixer,” and it’s a foul 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 on occasion about how if a pitcher had been by some means in a position to systematize the backup breaking ball — to throw it constantly quite than encounter it as a random error — he’d be unhittable, as a result of batters would don’t have any clue what to do with it. I’m questioning if that’s what Allen has accomplished right here. He’s constantly 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 price and lowest opponent wOBA and xwOBA. It is perhaps a weird-ass changeup, but it surely’s working.
