How Sticky Was It?

Kirby Lee-USA TODAY Sports

So far this year, there have been two ejections and suspensions for sticky stuff, along with two notable non-ejections. In all four instances — two of them just in the last week — the umpires involved made themselves available to a pool reporter for comment after the game. I cannot for the life of me imagine that the umpires want to be making these statements, but here’s the thing: So far as I can tell, they’re not required to. There’s no way that on an umpire’s list of favorite things to do after a game, Describe How Sticky Max Scherzer’s Hand Was ranks anywhere near the top 10. And yet, whether to justify their actions or out of a sincere belief that sunshine is the best disinfectant, the umpires have dutifully attempted to answer that impossible question. Not that I’m complaining. I adore these explanations. I don’t know how anyone could actually do a good job of explaining how sticky a hand was, but watching big league umpires give it their best shot is a truly rewarding experience.

I spent a morning trying to look up how tackiness is measured. It turns out there’s no one answer, but there is an ocean of scientific debate to dive into. I can now tell you the difference between probe testing, loop tack testing, the rolling ball test, and the peel adhesion test. Each test needs to account for variables like dwell time, contact pressure, temperature, and test speed. There’s also something called the finger test, which isn’t as gross as it sounds (but also probably is).

There are five different commercial products — some of them huge industrial machines — named either the Tack Tester or the Tackiness Tester. Koehler Instrument Company’s Tackiness Tester K95200 is the size of a refrigerator, and is used solely for the purpose of “measuring the cohesive and adhesive tactile properties of greases.” The point is: None of these methods is perfect. Or comprehensive. Or designed to test human fingers.

Science has yet to determine a definitive way of measuring tackiness, so it would be unreasonable to ask umpires to do so. But again, I’m thrilled that we’re asking them anyway. Their answers are poetry. Given the welded-shut needle those answers are attempting to thread, they can’t help but be poetry. Tell me you wouldn’t shell out for a slim chapbook full of gems like this one:

It’s not rosin.
It was not rosin.
It was definitely not rosin
(Because I’ve felt hands with rosin).
That wasn’t rosin.
It was extremely sticky.

In sports, we’re accustomed to calling things we can’t quite measure “intangibles.” Stickiness has got to be the world’s most tangible intangible, and trying to describe it leaves perfectly intelligent people producing sentences like, “Phil then asked me to come in to verify that the hand was too sticky.”

In any other context, that sentence would leave me with a whole lot of questions about Phil. As a general rule of thumb, any time someone asks you to verify that a human hand is sticky, let alone too sticky, you should run away.

According to Bryan Hoch, crew chief James Hoye said on Tuesday that Domingo Germán’s hand was, “the worst hand we’ve ever felt during a game,” which sounds more like a qualitative assessment. If I were Germán, I might be a little hurt.

There is one thing that umpires have been nailing. “Not tacky, sticky,” said Dan Bellino of Max Scherzer’s right hand in April. “It sounds silly, but there is a difference between tackiness and stickiness.” On Tuesday, Hoye said of Germán’s hand, “It was extremely sticky. And rosin usually is kind of like a little tackiness. This was sticky.” On Friday, crew chief Brian O’Nora made the same distinction when describing something stuck to Clarke Schmidt’s wrist: “He noticed something just a little tacky… It wasn’t sticky, and it wasn’t a foreign substance.” The dictionary definition of tacky is, “somewhat sticky to the touch,” and umpires have been using it to mean exactly that. A tacky hand is fine, but once it’s made the leap from somewhat sticky to fully sticky, there’s a problem.

I checked his pitching hand;
It was slightly sticky,
A little tacky.
And it was dark in color–
Which really isn’t a surprise.

When I looked at it
And looked at him
He said,
“No, it’s just rosin.
I’m going to wash it off.”

I said, “Okay–
You got to wash that off.”

Unfortunately, that’s pretty much the only language umpires can use to place things on the spectrum of adhesion. Even the thesaurus isn’t much help, though I would love it if an umpire characterized a pitcher’s hand as agglutinative. It’s like quantum physics. You’re either tacky or you’re sticky, with nothing in between, and umpires really only have one way of illustrating the difference. Of Scherzer, Bellino said, “Our fingers were sticking to his hand, and whatever was on there remained on our fingers afterwards for a couple of innings where you could still feel that the fingers were sticking together.” Really, how can you describe something sticky, other than to say that it stuck to you? The Tackiness Tester K95200 could tell us exactly how many newtons of force it takes to pull away from a pitcher’s hand, but it would have to crush that hand into a millimeter-thin pancake first. The only thing an umpire can say is, “My fingers had a hard time coming off his palm.”

That being the case, I think that umpires have been a bit reckless in burning through the superlatives so quickly. When Scherzer got suspended a month ago, crew chief Phil Cuzzi said, “It’s far stickier than anything that we’ve felt, certainly today and anything this year.” Bellino went even further, saying, “This was the stickiest it has been since I’ve been inspecting hands, which goes back three seasons.” You can’t come right out of the gate and say the first offender was the absolute stickiest you’ve ever touched! That’s just poor planning. It doesn’t leave any room for expansion. Now Germán also possesses the “stickiest hand I’ve ever felt.” Whose hand was actually stickier? After just two infractions, we’re already suffering from stickiness inflation. This is the same logic that’s turned the last 20 minutes of every superhero movie into one continuous explosion. Whoever gets caught next will have to have the stickiest hand in the galaxy. There’s nowhere else to go.

That’s really my only quibble, though. In addition to the stickiness factor, umpires have given detailed and reasoned explanations of the logic that led them to ask a pitcher to wash their hands, to change their gloves, and finally, to hit the showers. Here’s Bellino on Scherzer:

We have a universal rosin bag that Major League Baseball provides that we inspect before every game. So when we check these pitchers’ hands, we know what the rosin typically feels like on a pitcher’s hand because everyone’s using the same rosin bag. So it’s really important to understand that when they claim it’s just rosin, every pitcher we check, we check every pitcher every single game, and every pitcher we check, we’re accustomed to what that rosin residue will be on a pitcher’s hand … So we’re trying to really make sure that it’s a level playing field out there and that no one’s gaining an unfair competitive advantage. I know that’s the goal … I would just say, the most important aspect is, we were not quick to remove him from the game, understanding that removal from the game is a very big penalty, a very stiff penalty. The fact that he was given many opportunities and he was told that it was getting too far and that it continued to be an ongoing situation…

I have really appreciated those explanations. They gave me a better sense of how the game works and made me more of a believer in MLB’s innovative hand massage accountability system. Still, my favorite part was the very next words Bellino said: “The level of stickiness, it was just too much.”

What’s the difference between “stickiness” and “yuckiness”. There should be an official MLB policy on the degree of “yuckiness” allowed. Nose picking comes to mind

So now pitchers will continue to search for the highest level of tackiness that doesn’t rise to the level of stickiness.

I think they just need to do with pitchers the same thing I used to do with Lunchables: throw them against the ceiling; if they stick, it’s clear too sticky.

We need a full analysis of the difference between sticky, tacky, gummy, and gooey.

What are the qualitative and quantitative dimensions of each?
How do we know for sure?
Can umpires reliably distinguish between them in a blind-touch test?
Are there particular qualities of some people’s skin or sweat that leads them to be more of one or the other?

It seems to me that MLB just needs to concoct an approved substance and have it be the only substance allowed. Make it glow under black light or something, I don’t know. But it’s clear that pitchers feel more comfortable being able to get a better grip — and sure there is a performance benefit there — but players also view it as a player safety issue. Just keep it a level playing field and make it easy to adhere to the rule. If you go outside of those parameters, then MLB should come down with an extra heavy ax.

This already exists. The rosin bag. It doesn’t glow under black light, but the solution is already there and many violate anyway. No matter how sticky the rosin bag is allowed to become, some will want stickier.

I thought so too, but then Scherzer was suspended for using rosin and nothing else (since he washed his hands and applied it while being watched by an MLB employee, we can be fairly certain of that). So it’s not actually an approved substance, it’s an approved substance in certain quantities which you can get suspended for using some unknowable amount that ends up being too sticky in some ill-defined way. It’s a mess!

Rex Manning DayMember since 2022

Ah, but Scherzer cleaned his hands with alcohol, which it turns out everyone in baseball except MLB officials knows can make rosin even stickier.

That was easily the most baffling of these stickiness events, imo. The fact that an MLB official watched a player “clean” his hands with something that was widely known to increase stickiness is genuinely wild.

If you’re going to make a player clean their hands in front of you to make sure they’re following the rules, the absolute least you could do is know whether the soap they use is actually going to, you know, clean their hands.

Yup. Given that there was no preexisting rule or language about alcohol, and that they apparently watched him use the alcohol directly before ejecting and suspending him for its effect, it sure seems like they’re making the “rules” up as they go along!

Everything Davy Andrews writes is a must-read.

He’s got a YouTube channel too if you want to hear his music. The stuff I checked out were basically all kids songs, but a few of them are baseball-themed too (kids baseball songs!). I fully expect to see the contents of this article turned into song lyrics.

Moments after reading this I encountered the following lede in the newspaper: “Elevated car prices have proved uncomfortably sticky.” The problem is spreading!!!

Jay Powell definitely has his own Phil Cuzzi on-field spectrometer.

So basically, his T was way out of line with his FIT and the leagues xT

I get that it’s probably not feasible to have an on-field test capable of measuring stickiness and/or the presence of foreign substances, and so while it’s not perfect, letting umps eject pitchers based on their subjective judgement of stickiness seems fair enough. Umps can already eject players essentially at a whim, and an ejection seems like a reasonable enough punishment for using a bit too much of a legal substance.

But suspensions are a different animal, and “you’re allowed to use rosin, but not too much, and no we can’t tell you how much is too much, but yes we’ll suspend you if you use too much” doesn’t seem like a great system. And it also seems like it should be feasible to wipe an ejected pitcher’s hand with a towelette or whatever and send the sample off to a lab after the game to see what’s on there, and then base the suspension decision on those results.

Obviously there would be some details to work out. You’d have to account for sunscreen, for one thing. So maybe you make ejectees provide a list of all their lotions and soaps and whatever else they put on their bodies, so the lab can account for them. And maybe you even take samples from every pitcher a couple hours before the game, too, before they’ve applied anything at all, to serve as a baseline.

Whatever the details, while it wouldn’t be perfect, it would at least inject a nominal bit of objectivity into the process. And heck, maybe multiple ejections can still trigger a suspension regardless of the lab results, on account of you can’t just keep pushing the envelope without getting a whack on the nose eventually. But at present, it appears entirely possible for a player to believe in good faith that they’re following the rules and yet still get suspended, and that just seems like it should be avoidable.

Does a kleenex/notebook page/piece of felt stick to it? Too much!

Not sure what material should not stick to properly applied rosin, but there’s probably something that they could keep on hand for this (so to speak.)

Why is MLB unable to produce the baseballs that are standard in Japan?

A nice article with a T.S. Eliot reference under the headline. Thank you Fangraphs.

The fact that the umps for Scherzer and German used similar phrasing in their public statements, “the stickiest I’ve ever felt”, makes me think they’re coached to speak this way publicly about it. “Stickiest I’ve ever felt” is purely subjective and thus cannot be challenged, whereas if you say something is X and then it turns out to be Y, that might make them look sillier on what is essentially a judgment call. What’s too sticky to an ump? A sticky material is allowed in that you can use rosin, but how much rosin is too much? A pitcher adds more rosin to their hand as the game goes on, so can their hand BECOME too sticky after not being sticky earlier?
