Biometric scanning is coming to the ballpark. It’s a really bad idea.

It was announced last summer to relatively little fanfare, but after a few years in which only a couple of teams have done this on a small-scale basis, several more teams will be introducing biometric ticketing and concessions purchases in 2019. It’s a pilot program between Major League Baseball and Clear, the company behind fingerprint and facial recognition technology at airports and other places. As described in a typical story about it from last summer:

Clear members can link their profiles with their accounts, entering Comerica Park or Yankee Stadium or AT&T Park with just the tap of a finger—or maybe even facial recognition technology in the near future. The tech is still developing.

With the nod to people who like to say things like “the future is cool,” etc. etc., may I ask why anyone would willingly give their biometric over to get into a ballpark?

At the outset let me say that I am not one of those people who lose sleep at night worrying about data security. It’s a serious matter, yes, but I tend to think that the concerns about it can, at times, be overstated. I know Facebook, Twitter my mobile phone and all manner of other apps and devices are collecting data and are studying my habits. I don’t think it’s a good thing, but I also try to exercise as much common sense, employ enough password and security measures, and share as little truly critical personal information as I can. There is a real danger of data misuse and theft, yes, but at times some of the talk about it can, I think, be a tad overwrought and alarmist.

But biometric data is a bit different than, say, a social media profile or a record of the online retailers I like to browse. I can change my passwords and go incognito online. I can’t change my fingerprints. I can’t change my retinas. Once that data is collected, the collector can, theoretically, hold it forever. Or sell it to anyone. They may say they have no interest in doing that — and perhaps it’s bad for business to be seen as a company that shares your information with others — but there is nothing legally stopping them from doing it. There are no federal laws covering this and only three state laws about it at all. Only one of which, in Illinois, has anything approaching teeth.

The bigger question I have: why in the heck does baseball think this is necessary?

A glimpse of it can be seen in the quotes given by an MLB official last summer:

“Developing a partnership that will unify emerging identity technology and ticketing is reflective of our commitments to always improving ballpark accessibility and maintaining critical security standards.”

Like everyone else in post-9/11 society, baseball seems to think that using the word “security” as some sort of magical incantation explains everything that needs to be explained. That’s far from the case, of course.

You can read a good bit of why that is in this article at Vice from 2015, which reported on the first installation of Clear’s biometric technology in baseball, at Yankee Stadium. The upshot: while biometric technology can mostly assure that the person entering a stadium is who they say they are, baseball has never cared, one iota, that the person entering the stadium is who they say they are. You’re not ID-checked at the turnstile and you never have been.

There is, at present, the extraordinarily rare case of keeping out people who have otherwise been banned from the ballpark, but going forward this gives MLB the ability to know who is there and who is not. Is there a compelling security reason for that? Maybe there’s an argument for that, maybe there isn’t, but if MLB simply wanted to know that it could’ve required ID checks for everyone at either point of sale or point of entry a long time ago and it has never done that. I suppose it’s possible they want that but it’s too cumbersome to check IDs and Clear makes it all easier. But it’s not like MLB is mandating the use of Clear, so it’s still an opt-in process. If the need for knowing fan identity were truly compelling, it would not be opt-in, right?

Even with Clear, I’m not sure what kind of security enhancements will be realized. Fine, you know who’s in the ballpark. But there is no screening function achieved simply by giving your fingerprint to get in unless it’s linked to a hotline to the Department of Homeland Security or the FBI or something, and I feel like that would a whole different story. As it stands, a registration with Clear — which is free of charge for sports purposes — an ID and a set of fingers can get you into the ballpark, which anyone can get. As for the mechanics: before now there have been various stadium-by-stadium versions of Clear and there is mixed information about what security processes people who use Clear go through. The Vice article from 2015 had the user bypassing the metal detectors completely. I’m told that’s no longer the case, but a Yankees fan I spoke with who has used the service as recently as last year said that you’re still subject to security, but it’s an express line with a more lax wand-wave and bag check. 

So if there’s no obvious security enhancement why do this?

A source at Major League Baseball tells me that it’s mostly about streamlining the game-going experience. Specifically upon entering the park. Rather than scan tickets, one’s fingerprint basically takes care of that. It seems like a very, very small amount of streamlining if you ask me. You still have to go through the metal detectors or a wand and bag check, which is the real bottleneck, and the time it takes to get your fingerprint is not that much faster than the time it takes for the old guy with the little scanner to scan the bar code on your ticket. Major League Baseball corrected my earlier assumption that it holds on to the biometric data that is scanned — it does not keep that information; it merely confirms with Clear that you bought a ticket — but it has to be getting something out of this deal in order to allow Clear to set up shop at its ballparks and have access to its ticketing database. I speculated to my source that maybe it’s just money — the Doosans and the Camping Worlds and, perhaps, the Clears of the world make the league go ’round — but neither Major League Baseball nor Clear would comment about the specifics their business arrangement. Which, fair enough.

Then I reached out to Clear to ask them why a baseball fan should use the service.

A spokesperson for the company says that Clear wants fans to have access to a “trusted identity platform,” and that it wants fans to have “faster, predictable experiences from the time they arrive at the stadium until the time they leave.” Over time it envisions providing more services, such as “touch points at stadiums, biometric ticketing and concessions that fans can choose to take advantage of.” That’s a seemingly reasonable pitch and your mileage may vary as to whether you think that provides you value as a fan.

But there’s no escaping the fact that the mechanics of its system also provides Clear with a rich source of data. Via registration of its users and via the ability to pair up its users personal and biometric information with its commercial habits — in this case, going to baseball games, buying concessions or whatever — Clear is gathering data on its users. What they do with that data may not be anything to be concerned about — Clear is, well, clear, in stating that it “never rents or sells member data, biometrics or personally identifiable information of members to third parties.” Still, it’s worth noting that Clear for sports is free of charge, and as the old adage goes, if you’re not paying for the product, you ARE the product. There is value in the data you are giving to Clear in order to use it to get into the ballpark. And that’s before one acknowledges that even the best-designed data security operations can fail. There are a lot of people who would love to get into a database of fingerprints and retina scans tied to your address, email address and, possibly, your credit card data. I take the Clear spokesman at his word regarding their desire to safeguard user information — it’s terrible for business if they don’t — but no one is perfect and there are a lot of bored, greedy hackers in the world.

MLB’s partnership with Clear will, if you take advantage of it, cause you to turn over your biometric data. Maybe they do nothing with it, but huge swaths of the modern economy are based primarily on data and information and that has a big effect. Sometimes that effect is negative, sometimes it is beneficial, but it’s rarely neutral. Biometric access to the ballpark will change things for baseball fans, sooner or later. How you feel about that is up to you.

For now, I’m sticking with paper tickets and the old guy with the scanner.

That article has been removed since this post was published. The information regarding the number of states regulating biometric data and the lack of federal regulation regarding biometric data was and is, however, accurate. 

* The earlier version of this post referred to Major League Baseball “holding” your data or otherwise storing it. Major League Baseball stated to me, however, that it does not, in any way, hold or retain customers’ biometric data pursuant to its partnership with Clear. It merely confirms that fans who use Clear are ticketed to ballgames.

Olson blasts two HRs, Acuña has 4 hits as Strider, Braves overpower Phillies 11-4

Dale Zanine-USA TODAY Sports

ATLANTA – Given a seven-run lead in the first inning, Atlanta right-hander Spencer Strider could relax and keep adding to his majors-leading strikeout total.

“That game felt like it was over pretty quick,” Strider said.

Ronald Acuña Jr. drove in three runs with four hits, including a two-run single in Atlanta’s seven-run first inning, and the Braves beat the Philadelphia Phillies 11-4 on Sunday night to split the four-game series.

“Getting a lead first is big, especially when you get that big of a lead,” Strider said. “… When we’re putting up runs, my job isn’t to be perfect. My job is to get outs.”

Following the game, Braves manager Brian Snitker announced right-hander Michael Soroka will be recalled to make his first start since the 2020 season on Monday night at Oakland.

Matt Olson hit a pair of two-run homers for Atlanta, and Strider became the fastest pitcher in modern history to reach 100 strikeouts in a season.

“It’s incredible,” said Acuña through a translator of Strider. “Every time he goes out to pitch it seems like he’s going to strike everybody out.”

Acuña hit a run-scoring triple in the fifth before Olson’s second homer to center. Acuña had two singles in the first when the Braves sent 11 batters to the plate, collected seven hits and opened a 7-0 lead. Led by Acuña and Olson, who had three hits, the Braves set a season high with 20 hits.

Strider (5-2) struck out nine while pitching six innings of two-run ball. The right-hander fired a called third strike past Nick Castellanos for the first out of the fourth, giving him 100 strikeouts in 61 innings and topping Jacob deGrom‘s 61 2/3 innings in 2021 as the fastest to 100 in the modern era.

“It’s cool,” Strider said, adding “hopefully it’ll keep going.”

Olson followed Acuña’s leadoff single with a 464-foot homer to right-center. Austin Riley added another homer before Ozzie Albies and Acuña had two-run singles in the long first inning.

Phillies shortstop Trea Turner and left fielder Kyle Schwarber each committed an error on a grounder by Orlando Arcia, setting up two unearned runs in the inning.

Strider walked Kody Clemens to open the third. Brandon Marsh followed with a two-run homer for the Phillies’ first hit. Schwarber hit a two-run homer off Collin McHugh in the seventh.


Michael Harris II celebrated the one-year anniversary of his major league debut by robbing Schwarber of a homer with a leaping catch at the center-field wall in the second. As Harris shook his head to say “No!” after coming down with the ball on the warning track, Strider pumped his fist in approval on the mound – after realizing Harris had the ball.

“He put me through an emotional roller coaster for a moment,” Strider said.


Soroka was scratched from his scheduled start at Triple-A Gwinnett on Sunday, setting the stage for his final step in his comeback from two torn Achilles tendons.

“To get back is really a feather in that kid’s cap,” Snitker said.

Soroka will be making his first start in the majors since Aug. 3, 2020, against the New York Mets when he suffered a torn right Achilles tendon. Following a setback which required a follow-up surgery, he suffered another tear of the same Achilles tendon midway through the 2021 season.

Soroka suffered another complication in his comeback when a hamstring injury slowed his progress this spring.

Acuña said he was “super happy, super excited for him, super proud of him” and added “I’m just hoping for continued good health.”

Soroka looked like an emerging ace when he finished 13-4 with a 2.68 ERA in 2019 and placed second in the NL Rookie of the Year voting and sixth in the NL Cy Young voting.

The Braves are 0-3 in bullpen committee games as they attempt to overcome losing two key starters, Max Fried (strained left forearm) and Kyle Wright (right shoulder inflammation) to the injured list in early May. Each is expected to miss at least two months.

RHP Dereck Rodriguez, who gave up one hit in two scoreless innings, was optioned to Gwinnett after the game to clear a roster spot for Soroka.


Phillies right-hander Dylan Covey (0-1), claimed off waivers from the Los Angeles Dodgers on May 20, didn’t make it through the first inning. Covey allowed seven runs, five earned, and six hits, including the homers by Olson and Riley.


Phillies: 3B Alex Bohm was held out with hamstring tightness. … LHP José Alvarado (left elbow inflammation) threw the bullpen session originally scheduled for Saturday. Manager Rob Thomson said there was no report that Alvarado, who was placed on the injured list on May 10, had any difficulty.


Phillies: Following an off day, LHP Ranger Suárez (0-1, 9.82 ERA) is scheduled to face Mets RHP Kodai Senga (4-3, 3.94 ERA) in Tuesday night’s opener of a three-game series in New York.

Braves: Soroka was 1-2 with a 4.33 ERA in eight games with Triple-A Gwinnett. He allowed a combined four hits and two runs over 10 2/3 innings in his last two starts. RHP Paul Blackburn (7-6, 4.28 ERA in 2022) is scheduled to make his 2023 debut for Oakland as he returns from a finger injury.
