Baseball is changing forever with robot ump challenges
NEWYou can now listen to Fox News articles!
For generations, baseball has followed a simple rule. The umpire calls balls and strikes, and that call stands. That changes now. This season, Major League Baseball is introducing something that once felt unthinkable. Players can challenge an umpire’s call and let technology decide the outcome.
It is called the Automated Ball-Strike Challenge System, or ABS. Most fans already know it by another name. The robot ump. And whether you love it or hate it, the game is stepping into a new era.

What is the MLB robot ump challenge system?
At a basic level, ABS uses advanced cameras to track every pitch with precision. It creates a digital strike zone that removes guesswork. But MLB is not handing full control to machines just yet.
Instead, this is a hybrid system. Human umpires still make every call on the field. Players now have a limited way to challenge those calls when they believe something was missed. So the umpire still runs the game. Technology simply keeps them honest.
How the robot ump actually sees every pitch
The system uses a network of high-speed cameras placed around the stadium to track the baseball in three dimensions. It measures the pitch as it crosses home plate and compares it to a digital strike zone that is customized to each batter’s height.
All of that happens in milliseconds. The result is sent almost instantly to the scoreboard, which is why the challenge feels fast and seamless instead of disruptive.
Scott Jacka, Sr. Director of Technology Development Strategy at T-Mobile, told CyberGuy:
“T-Mobile’s private 5G network enables the real-time transmission of pitch data to the ABS operator during ABS challenges. As pitches are tracked by cameras around the field, that data is transmitted quickly and reliably to the ABS system operator in the press box, who can then deliver the results back to the field within seconds.”
Jacka added:
“ABS depends on fast, reliable data transmission in a live game environment. T-Mobile’s private 5G network is designed to provide secure, low-latency connectivity through a dedicated spectrum in every U.S. MLB stadium. This helps pitch data move quickly and consistently so decisions can be delivered without disrupting the rhythm of play.”
How the challenge system works during a game
The process is surprisingly simple and fast. Each team starts with two challenges per game. Only the pitcher, catcher or batter can call for one. No dugout help. No replay delays.
The player signals by tapping their head. Within seconds, the stadium screen shows the pitch location and whether it was truly a ball or a strike. If the challenge is correct, the team keeps it. If not, they lose one.
That quick moment has already become one of the most intense parts of the game. Teams may also receive additional challenges in extra innings, giving them a bit more flexibility in longer games.
What happens if the tech gets it wrong
One big concern with any new system is reliability. MLB designed ABS to deliver results almost instantly, without slowing down the game.
If anything ever goes wrong, the human umpire is still there as the final authority. That built-in fallback helps ensure the game keeps moving smoothly without long delays or confusion.
Who is powering the robot ump tech?
The system behind MLB’s robot ump is powered by Hawk-Eye Innovations, the same camera tracking technology used in tennis and soccer for line calls and goal decisions. That alone gives the system a proven track record for accuracy.

Why MLB decided now was the time
Bad ball and strike calls have always been part of baseball. Sometimes they even become part of the story. But fans, players and teams have grown less patient with mistakes that technology can easily fix. MLB sees this system as a way to clean up the most frustrating part of the game without removing the human element entirely.
It is not about perfection. It is about fairness in the biggest moments.
Why fans might end up loving it
You might expect this to slow things down. It does the opposite. Every challenge creates a moment. The crowd pauses. The screen lights up. Everyone waits for the answer.
It adds tension without dragging out the game. Even better, it removes the endless arguing. Instead of debating calls for hours, fans get a clear answer almost instantly. It turns controversy into drama.

Why timing and emotions matter more than ever
One of the biggest lessons from early testing is that when you challenge matters more than what you challenge. Players who use challenges too early may regret it later in high-pressure moments.
There is also a human factor. Players admit emotions can get the best of them, leading to impulsive challenges that cost their team later in the game.
Some pitches are harder to judge than others
Not every pitch is easy to challenge. High-velocity pitches and those with heavy movement, like sinkers, can be extremely difficult to judge in real time.
Even experienced players can misread a pitch by inches, which makes deciding whether to challenge even more difficult.
How MLB players feel about robot umps
This is where things get interesting. Hitters with elite plate discipline could gain an edge. Players like Juan Soto are known for recognizing the strike zone better than almost anyone. That skill now has real strategic value.
Catchers face a different reality. Pitch framing has long been one of the most valuable defensive skills in baseball, where catchers subtly position their glove to make pitches look like strikes to the umpire. With ABS, framing is not disappearing. Instead, it is evolving into a more strategic tool while still influencing live calls from the human umpire.
Pitchers are the least likely to use the system. Many do not believe they have the best view of the strike zone in real time. Veterans like Max Scherzer have also raised a bigger question. How much technology should be allowed to shape the game? That debate is far from settled.
The hidden data boom behind robot umps
Beyond making calls, ABS is generating a massive amount of data. Teams can now analyze pitch accuracy, player tendencies and challenge success rates in real time.
This opens the door to deeper analytics, from evaluating hitters’ strike zone awareness to measuring how effective catchers are at identifying missed calls. Over time, this data could influence coaching decisions and even player value.
Could this lead to full robot umps?
That question is already on the table. MLB has tested fully automated strike zones in the minor leagues. Other sports like tennis have already moved in that direction.
But baseball is different. Many players and fans still want a human behind the plate. They believe the personality, judgment and even the imperfections are part of what makes the game special.
Right now, the challenge system feels like a middle ground. It fixes the worst mistakes while keeping the human touch.

What this means to you
If you watch baseball, you will notice the difference right away. Games could feel fairer. Big moments are less likely to hinge on a missed call. You will also see more strategy. Players must decide when to challenge and when to hold back. One wrong decision could matter later in the game.
Teams are already treating challenges like a limited resource, often saving them for the most important moments late in the game. If you are a casual fan, this may actually make baseball easier to follow. The strike zone becomes visible and understandable in real time. In short, the game becomes more transparent, more strategic and more engaging.

Kurt’s key takeaways
Baseball has never stood still. From instant replay to pitch clocks, the game keeps evolving while trying to protect what makes it unique. The robot ump challenge system fits that pattern. It does not replace umpires. It simply gives players a voice when something looks wrong. And in a sport built on inches, that voice could change everything.

A long time ago, in 2004, the Federal Communications Commission laid down a rule designed to prevent a monopoly: No one company could broadcast to more than 39 percent of all the TV households in the United States. But then Donald Trump returned to the White House in 2025. Brendan Carr became FCC chairman and immediately kicked off a deregulatory initiative called “Delete, Delete, Delete,” in which Carr vowed to get rid of “every rule, regulation, or guidance document” that placed “unnecessary regulatory burdens” on companies. And within months, Nexstar, which already owned over 200 stations nationwide and had hit its ownership cap, announced that it had entered an agreement to purchase its rival, Tegna, for an estimated $6.2 billion — something that could only happen, however, if Carr agreed to change the FCC’s rules.
If you ask Nexstar why it’s pursuing a merger that would give it control of over 80 percent of the market, it’d point to Big Tech as the culprit. As advertisers take their money to Netflix, YouTube, and other digital streamers, linear television — the local television news, the broadcast affiliates, the basic cable networks — has suffered, forcing them to consolidate and shut down newsrooms. In that sense, Nexstar argued, the merger would help it compete for ad revenue with the streaming services, thereby building more robust local journalism. However, the merger’s opponents believe that this is a basic violation of antitrust laws and principles — not to mention the danger of letting one company have editorial control over the vast majority of America’s local television newsrooms.
But the second Trump administration handles regulatory hurdles a little differently than others, and companies have found that it’s faster to get what they want if they bypass the agencies and talk (read: suck up) to Trump directly. And when Nexstar did so publicly, it confirmed its opponents’ fears about political influence. Last September, in the fraught weeks after the fatal shooting of Charlie Kirk, Nexstar announced it would no longer broadcast Jimmy Kimmel Live! — a response to Carr’s claim that the FCC could revoke the broadcast licenses of TV stations that aired the comedian’s comments related to Kirk. It briefly led to ABC suspending Kimmel’s show, though ABC and Nexstar soon reversed their decision after a massive nationwide backlash and an ABC boycott.
However, Nexstar’s loyalty to Trump himself was not enough to win over his most powerful MAGA supporters. Newsmax, a cable news network with a deeply pro-Trump bent, and its CEO, longtime Trump donor and outside adviser Chris Ruddy, filed a lawsuit objecting to the merger, claiming that Nexstar’s anticompetitive behavior would force channels like his off the air with steeper carriage fees. He specifically accused Nexstar of jacking up the fees for stations to carry Newsmax, while offering its similar network, NewsNation, for much cheaper.
The Nexstar-Tegna MAGA makeover then took a more subtle turn. NewsNation hired the pro-Trump Fox News commentator Katie Pavlich and gave her her own primetime show. (The network had already hired a slew of former Fox journalists as well.) Around this time, a political group called Keep News Local began airing ads in DC that seemed to directly address Trump, praising him for having “defeated the fake news monopolies before through independent voices and local news” and claiming that the Nexstar-Tegna merger was “crucial for MAGA to survive.” (A little self-contradictory and mildly illogical, but it’s the kind of stuff that Trump likes to hear.) When I last spoke to Ruddy in February, I asked if he’d worried that the dark money going into Keep News Local would sway Trump, and he chose his words carefully: “I think at the end of the day, Trump makes up his own mind. I’m not sure he’s going to be influenced by an ad campaign.”
For months, no one could accurately predict if Trump would override Carr’s wishes and bless the deal, as he’s often done for other companies facing regulatory scrutiny. Trump’s Truth Social posts about the merger have been a good indicator of how precarious the merger has been and who’s been able to influence him at any given moment: Last November, he blasted the deal as an “EXPANSION OF THE FAKE NEWS NETWORKS,” but by February, he posted that the deal would “help knock out the Fake News because there will be more competition.”
Several current and former NewsNation employees told Status at the time that they feared that the parent company was steering NewsNation away from the centrist, “unbiased” reputation they’d long cultivated. “A lot of people within the network believe that the network has gone hard right to appeal to Trump and Brendan Carr,” one former employee told Status. Coincidentally, days before the deal was finalized, NewsNation began ramping up its explicitly pro-Trump content, tweeting a clip of CNN’s Kaitlan Collins being berated by White House press secretary Karoline Leavitt, along with the comment “Just going to leave this here.”
When Trump greenlit the merger in mid-March, but before the FCC’s three commissioners could vote on whether to waive the ownership cap, Nexstar and Tegna immediately announced a new complication: Tegna and Nexstar had already started merging. Tegna was no more and CEO Mike Steib had already sold $22.6 million of his company stock.
In response, eight state attorneys general and satellite TV operator DirectTV, which had already been planning to file separate federal antitrust suits against the merger, asked US District Judge Troy Nunley in Sacramento for an emergency restraining order that would prevent Nexstar from taking over Tegna’s assets. The order was granted on March 27th and on April 17, Nunley issued a formal injunction, ruling that Tegna must be operated as an independent financial entity, and Nexstar must take steps to ensure it remains separate from Tegna before further legal proceedings.
For now, Nunley has allowed the states and DirecTV to combine their cases, in which both argue that the merger was a clear violation of antitrust laws and would crush news competition.
Meanwhile, Republicans and Democrats in Congress are furious at Carr. On March 30th, Sens. Ted Cruz (R-TX) and Maria Cantwell (D-WA) sent the chairman a joint letter admonishing him for allowing his staff to waive the regulations to let the merger pass, instead of having the full commission of political appointees — one from the Biden administration — vote on it. “Under these circumstances,” they wrote, “any subsequent vote risks being largely procedural rather than a genuine exercise of commission responsibility.” They also pointed out that their hasty approval without the commission’s approval would now complicate the merger financially: “In a transaction of this scale, where integration proceeds quickly and unwinding becomes impractical, delay in judicial review can insulate the decision from meaningful challenge.” Notably, though they share similar ideological views on the media and deregulation, Cruz and Carr have frequently clashed over how to achieve their objectives. Cruz previously slammed Carr as a “mafioso,” for instance, for the way he’d used the FCC to silence Kimmel.
But even if it’s legally paused, the journalistic merger’s fallout has started to hit local news. NPR’s David Folkenfirk reported on Tuesday that Tegna journalists had already started receiving orders to stop broadcasting content from major broadcasters like ABC, CBS, and NBC — media outlets being targeted by Carr — and instead begin airing content from Nexstar’s NewsNation.
- Brendan Carr’s views on using the FCC to punish major broadcasters was outlined pretty extensively in the chapter he authored in Project 2025, an initiative led by the conservative Heritage Foundation on how to reform the federal bureaucracy to be more favorable to the American right.
- Exactly how much is local television losing to digital? According to industry publication NewscastStudio, in an investor call defending the purchase, Nexstar chairman Perry Sook cited a market research study from Borrell Associates, which found that “digital advertising in local markets exceeds $100 billion, compared to just $25 billion for local linear television advertising, with nearly two-thirds of digital ad dollars flowing to five major technology companies.”

A Chinese-built humanoid robot beat the human half-marathon world record in Beijing on Sunday, marking a breakthrough moment in a high-stakes global race for technological dominance.
A robot developed by Chinese smartphone maker Honor completed the 21-kilometer (13-mile) race in 50 minutes and 26 seconds, beating the human record of about 57 minutes set by Uganda’s Jacob Kiplimo last month.
The performance marked a dramatic improvement from last year’s inaugural event, when the top robot finished in more than 2 hours and 40 minutes.
Dozens of humanoid robots competed alongside about 12,000 human runners, navigating a parallel course to avoid collisions.

Nearly half of the robots ran using autonomous navigation, while others relied on remote control, organizers said.
Despite the breakthrough, the race still saw glitches, with some robots stumbling at the start or veering into barriers.
Engineers said the winning robot was designed to mimic elite athletes, featuring long legs of about 37 inches and advanced cooling systems to sustain performance.

“Looking ahead, some of these technologies might be transferred to other areas,” said Du Xiaodi, an engineer with the Honor team. “For example, structural reliability and liquid-cooling technology could be applied in future industrial scenarios.”

Spectators reacted with a mix of amazement and unease at the machines’ rapid progress.
“It’s the first time robots have surpassed humans, and that’s something I never imagined,” Sun Zhigang, who attended the event with his son, told The Associated Press.
HUMANOID ROBOTS HIT MASS PRODUCTION IN CHINA
“The robots’ speed far exceeds that of humans,” spectator Wang Wen told the outlet. “This may signal the arrival of sort of a new era.”

Experts say the race highlights China’s accelerating push to dominate robotics and artificial intelligence, even as widespread commercial use of humanoid robots remains limited, according to Reuters. The experts said Chinese robotics firms are still working to develop the AI software needed for humanoids to match the efficiency of human factory workers.

According to Nikkei Asia, even as suppliers ramp up DRAM production, manufacturers are only expected to meet 60 percent of demand by the end of 2027. SK Group chairman has even said that shortages could last until 2030.
The world’s largest memory makers — Samsung, SK Hynix, and Micron — are all working to add new fabrication capacity, but almost none of it will be online until at least 2027, if not 2028. SK opened a fab in Cheongju in February, but that is the only increase in production among the three for 2026.
Nikkei says that production would need to increase by 12 percent a year in 2026 and 2027 to meet demand. But according to Counterpoint Research, an increase of only 7.5 percent is planned.
The new facilities will primarily focus on producing high-bandwidth memory (HBM), which is used in AI data centers. With the companies already prioritizing HBM over general-purpose DRAM used in computers and phones, it’s not clear how much these new fabs will help alleviate the price crunch facing consumer electronics. Everything from phones and laptops, to VR headsets and gaming handhelds have seen price increases due to the RAM shortage.
