Yankees' 'Torpedo Bats' Fuel Record-Breaking 9-Home Run Game

MLB confirms legality of innovative bat design as debates grow over its impact on baseball's competitive balance.

The New York Yankees hit a franchise-record nine home runs in a 20-9 victory over the Milwaukee Brewers on March 28, 2025, with several players using newly designed 'torpedo bats.'
The 'torpedo bats,' developed by former Yankees analyst and MIT physicist Aaron Leanhardt, feature a unique weight distribution to optimize the sweet spot and reduce mishits.
MLB has confirmed that the bats comply with league regulations, but their use has sparked discussions about fairness and innovation in the sport.
While players like Anthony Volpe and Jazz Chisholm Jr. have embraced the bats with notable success, Aaron Judge has chosen to stick with his traditional equipment, citing confidence in his established approach.
Speculation is growing that other teams may adopt similar bat designs if they remain permissible, potentially reshaping the competitive dynamics of MLB.
