AI-powered bat tracking could give baseball players the edge
NEWYou can now listen to Fox News articles!
Baseball teams have long searched for a way to study the entire swing without sensors or complex lab setups. Today, a new solution is entering the picture. Theia, an AI biomechanics company, debuted a commercially available video-only system that analyzes bat trajectory and full-body biomechanics together. This new approach works in real baseball environments and needs no reflective body markers, wearables or special equipment.
The system has been field-tested by Driveline Baseball and the San Diego Padres Biomechanics Lab, and the tests show it delivers high-quality results in both cages and on the field.

A new chapter in baseball biomechanics
Theia’s platform relies on deep-learning models trained on millions of movement data points. It captures the full 3D bat path, attack angle, sequencing and body motion in one workflow that teams can run with standard high-speed video. This makes advanced biomechanics more accessible to coaches and players who train in normal environments.
Dr. Arnel Aguinaldo of the PLNU Biomechanics Lab tested the system with the Padres. He said, “Theia’s markerless technology represents a breakthrough in how we capture and analyze swing mechanics. It removes the barriers of traditional setups, letting us gather quality swing data directly from the field or the cage. That’s a game changer for both research and applied development.”
Independent testing across more than 2,000 swings showed median bat-plane angle differences of less than 3 degrees compared with marker-based systems. As a result, teams can evaluate roster-sized groups in routine cage or field sessions without slowing players down.
Why video-only tracking works in real baseball settings
Many existing tools rely on sensors or suits that can change how an athlete moves. Marcus Brown, CEO of Theia, explained to CyberGuy why video-only tracking matters.
“Using only video means teams get lab-grade biomechanics data that previously required a full lab setup, but without special suits, reflective markers, or hardware mounted to the bat or the player,” he said.
The system runs in the background once cameras are placed and calibrated. Coaches record sessions as usual, and the analysis processes automatically. Because of this, training routines stay the same, and players move naturally.
Brown added, “Until now, full swing analysis meant choosing between bat-only tools or biomechanics labs that couldn’t scale. Our new markerless technology changes that. Teams can now see the complete swing picture for every hitter using one system in an environment that matches their individual needs.”
How AI bat and body tracking improves player performance
A complete swing view gives coaches the chance to link body motion to bat results. Brown described why this matters for player development.
“Theia’s new bat tracking feature helps players improve because it gives coaches a complete and more accurate picture of the swing. Many tools today either measure the bat or the body, and many rely on wearables or sensors that can influence how an athlete moves,” Brown said. “When coaches can connect a player’s sequencing, posture, timing, and rotation to the bat’s path, speed, and contact quality, they can identify the specific movement patterns that drive results. That makes mechanical adjustments more targeted and much easier to track over time, leading to more consistent and meaningful improvements.”

What players experience when teams use Theia’s system
Players will not need to attach anything to the bat or their bodies. They swing in their regular training spaces without changing behavior. Brown said, “For athletes, the biggest change is the level of precise personalized feedback they get. Coaches can isolate whether an issue is coming from sequencing, posture, timing, or how the hitter is delivering the barrel to the ball. That level of detail helps translate mechanical work in the cage into more consistent, reliable results in the field.”
Independent testing shows consistent bat and body data
Driveline Baseball and the PLNU x Padres Biomechanics Lab tested the system in both professional and collegiate settings. Brown said, “Our work with Driveline and the PLNUxPadres’ Biomechanics Lab showed the system could deliver high-quality bat-and-body data in the same environments where hitters actually train. What those tests demonstrated was consistency: the ability to capture the full swing automatically, link the bat and body with the precision needed for player development, and fit seamlessly into a normal training session.”
Why Theia’s system fits seamlessly into normal cage sessions
Sports tech can create workflow friction, but Theia aims to avoid that. Brown said, “We designed the system so coaches can use it without changing anything about their normal training routine. Once the cameras are in place, coaches simply record the session the same way they normally would, and the analysis happens automatically in the background.”
There are no extra steps, no equipment put on the players, and no training interruptions.

The road ahead for AI sports performance
Brown believes this breakthrough sets the stage for future innovation.
“Player development is ultimately about understanding what drives performance, and this technology gives coaches a far clearer way to see that,” he said. “When you can connect a player’s movement to the result of the swing with objective repeatable data, you can build training plans that are far more individualized and precise.”
He also added: “This work builds on more than a decade of research and over 50 peer-reviewed validation studies focused on highly accurate markerless human motion tracking. It reflects where the field as a whole is headed toward integrated markerless solutions that give athletes and coaches clearer insight with far less friction.”

The future of local TV news has taken a Trumpian turn
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.”

Chinese robot breaks human world record in Beijing half-marathon
NEWYou can now listen to Fox News articles!
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.

The RAM shortage could last years
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.
