The crowd at Yankee Stadium witnessed history Saturday as the New York Yankees demolished the Milwaukee Brewers 20-9 in an offensive showcase featuring a franchise-record nine home runs. But beneath the cheers and fireworks, controversy brewed over the Yankees’ unique bat technology that has some fans crying foul.
The offensive onslaught began immediately when Paul Goldschmidt, Cody Bellinger, and Aaron Judge smashed consecutive home runs on the first three pitches thrown by former Yankee Nestor Cortes. Judge dominated the day with three homers—including a second-inning grand slam—and eight RBIs, establishing himself as an early MVP contender for the 2025 season.
Austin Wells, Anthony Volpe, and Jazz Chisholm joined the home run parade, with the Yankees launching eight bombs by the fourth inning to build a commanding 16-4 lead. A ninth homer later cemented a new franchise record.
Broadcaster’s revelation sparks Yankees blame game
The power display took a controversial turn when YES Network’s Michael Kay drew attention to something unusual about the bats wielded by Volpe and Chisholm.
“You see the shape of Chisholm’s bat?” Kay remarked during the broadcast. “The Yankees’ front office, the analytics department, did a study on Anthony Volpe, and every single ball it seemed like he hit on the label. He didn’t hit any on the barrel, so they had bats made up where they moved a lot of the wood into the label so the harder part of the bat is going to actually strike the ball.”
The Yankees made newly-shaped bats that moved more of the wood into the label, so the hardest part of the bat strikes the ball.
This casual observation triggered an immediate social media storm, with fans flooding MLB’s accounts demanding an investigation.
“@MLB gonna need the Yankees bats checked. Thank you kindly,” demanded one Twitter user.
Another complained, “Wow, I guess Rob Manfred should put a stop to these cheaters,” while others sarcastically called for New York’s disqualification from postseason contention.
The uproar grew loud enough that many expected MLB to launch an official inquiry, though the league has remained silent on the matter.
Innovation or rule-bending?

Despite the outcry, the Yankees appear to be operating within MLB guidelines. According to MLB Rule 3.02, bats must be “smooth, round sticks not more than 2.61 inches in diameter at the thickest part and not more than 42 inches in length.” On-field inspections confirm the Yankees’ bats meet these specifications.
The innovation lies in the internal weight distribution—specifically, concentrating wood in areas where players frequently make contact. This data-driven approach emerged after analytics revealed Volpe consistently hit balls off the label rather than the barrel, prompting equipment modifications to enhance his performance.
Currently, only Volpe and Chisholm have fully implemented the new design, while Bellinger uses a modified version.
According to Chris Kirschner of The Athletic, the MLB has also given the bats a go-ahead. “Just to put this to bed, MLB says the new bats the Yankees are using are legal,” he wrote.
The man behind Yankees’ new bats
Ex-Yankees infielder Kevin Smith has provided more details about the origin of these bats. According to him, MIT physicist Aaron Leanhardt, who is on the Yankees payroll, created these “torpedo” bats for the team.
Yes, the Yankees have a literal genius MIT Physicist, Lenny (who is the man), on payroll. He invented the “Torpedo” barrel. It brings more wood – and mass – to where you most often make contact as a hitter. The idea is to increase the number of “barrels” and decrease misses. pic.twitter.com/CsC1wkAM9G
“They also feel a little lighter, there’s more weight closer to your hands so you can swing a heavier bat,” he said. “It kind of feels like those old Wiffle ball bats you used as a kid, the barrel feels MASSIVE the first time you pick it up. But it’s really not THAT big …
“It looks really big because the cup of the bat is smaller. Taking some of the wood away from the end (where you don’t really want to hit it anyways) and putting more in the barrel (where you want to hit it more) makes it look even bigger. It makes sense to everyone who plays, the hard part is getting over how weird it looks in your hands. Looking down at it in the box made me laugh almost every time and most catchers noticed it. Players love feel, and it throws off all your feels initially. Obviously, it’s not going to make you an elite hitter if you aren’t already (I tried). But for the best in the world, any slight advantage could be the difference. It’s cool to see more people using them, Lenny was always amazed it wasn’t already a thing.”
Data-driven equipment evolution
This equipment customization reflects baseball’s broader trend toward analytics-based optimization. Teams now routinely employ bat tracking, swing path modeling, and biomechanical analysis in player development at all levels.
The results for Volpe and Chisholm were immediate and dramatic. Both players launched towering home runs Saturday, validating the scientific approach to equipment design.
This strategy aligns with the Yankees‘ offseason philosophy of blending young talent with cutting-edge methods. While the acquisitions of Chisholm and Goldschmidt demonstrated competitive intent, it’s the behind-the-scenes technological innovations that might provide the organization’s true competitive advantage.
Baseball’s evolving equipment landscape

The bat controversy underscores the constant evolution of baseball equipment. Throughout history, the sport has seen knobless bats, cupped ends, handle flares, weighted knobs, altered balance points, and customized grips—all within rule parameters.
An anonymous AL executive told Pinstripes Nation that without a clear violation of Rule 3.02, these modifications were comparable to using custom gloves or modified cleats. The executive added that this situation highlighted how innovation in baseball extends beyond analytics into equipment development.
However, in baseball’s post-Astros scandal environment, even minor equipment modifications face heightened scrutiny. The Yankees, as baseball’s most recognizable franchise, naturally attract additional attention when pushing boundaries.
Power surge creates PR Challenge
Saturday’s victory gave the Yankees a perfect 2-0 start to their 2025 campaign but also placed them at the center of a developing controversy about equipment innovation.
Major League Baseball has not announced any formal review, and no official statement addressing the bat designs has been issued.
For now, the Yankees’ innovative approach remains legal though highly scrutinized. If offensive production continues to surge—particularly if more players adopt similar equipment—expect the debate to intensify throughout the season.
One certainty remains: the Bronx Bombers have returned with a scientifically-enhanced vengeance.
Fans stands for Yankees

A lot of people are criticizing the Yankees for re-designing bats, where more wood is placed on typical points of contact based on data obtained via analytical research.
