MLB Needs to Put a Stop to the Yankees' Torpedo Bats
The Yankees’ Secret Weapon: Are Their New ‘Torpedo Bats’ Giving Them an Unfair Advantage?
The New York Yankees may have just discovered the closest thing to a legal performance enhancer in Major League Baseball—but it’s not in the form of a pill or injection. It’s a baseball bat.
On Saturday, the Yankees made history by launching a franchise-record nine home runs in a win over the Milwaukee Brewers. They followed that up on Sunday with homers from Aaron Judge and Ben Rice, securing a perfect 3-0 start to the season. But while the Bronx Bombers’ power surge is making headlines, it’s the bats they’re using that have become the biggest story in baseball.
A Game-Changing Innovation
These aren’t just any bats. The Yankees have reportedly developed a new, slightly unorthodox design that shifts the majority of the bat’s weight toward the barrel—specifically, around the label. This tweak optimizes the area of contact, allowing hitters to generate more power and consistency at the plate.
For the skeptics out there, yes, these bats are perfectly legal. But it’s not as simple as showing up with an oversized Wiffle ball bat. The mastermind behind this innovation? Former MIT physicist-turned-bench coach Aaron Leanhardt, who worked with Yankees hitters to develop custom-designed bats tailored to each player’s swing mechanics and contact tendencies.
“Where are you trying to hit the ball? Where are you trying to make contact?” Leanhardt told The Athletic in a recent phone interview. By analyzing each hitter’s tendencies, the Yankees created bats with an optimized weight distribution, making it easier for their sluggers to square up pitches with force.
Leanhardt has since moved on to the Miami Marlins as a field coordinator, but the impact of his invention is still being felt in New York. According to Cody Bellinger, at least five Yankees hitters are currently using these so-called “torpedo bats,” and early results suggest they are game-changing.
Innovation or Unfair Advantage?
Let’s call it what it is—this is straight out of a baseball mad scientist’s playbook. The Yankees saw Juan Soto walk in free agency, knew they needed an edge, and found one in a lab. Chess, not checkers.
But while the bats are technically within MLB’s rules, their introduction raises serious questions about fairness and competitive balance. Unlike a simple swing adjustment or a new training method, these bats provide a tangible, mechanical advantage that other teams don’t yet have access to. In order for other clubs to catch up, they would need to conduct their own research, develop their own variations, send them to a manufacturer, and wait for them to be produced before their players could even start testing them.
“I’ve never seen anything like it before,” said Brewers closer Trevor Megill. “It might be bush league. It might not be. But it’s the Yankees, so they’ll let it slide.”
The issue here isn’t just the bats themselves—it’s the precedent they set. If the Yankees can legally create an enhanced bat that gives them a competitive advantage, what’s stopping other teams from pushing the limits even further? If every team starts crafting their own custom bat designs, MLB could soon find itself in a Wild West-style arms race of bat technology.
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

MLB Needs to Step In
Major League Baseball has already had to crack down on pitchers using illegal substances for enhanced grip and spin rates. Now, they might need to take a similar stance with hitters. If these torpedo bats prove to be as impactful as early results suggest, the league must step in before the situation spirals out of control.
At the end of the day, baseball is built on the idea of a level playing field. The Yankees’ latest innovation might be the hottest topic in the sport right now, but if the league doesn’t act fast, it could lead to a new era of controversy over equipment regulations and unfair advantages.
For now, the Yankees have figured out how to maximize their firepower legally. But don’t be surprised if MLB steps in soon to rewrite the rules—because right now, New York might be playing chess while everyone else is stuck playing checkers.
