The New York Yankees have ignited a significant shift in Major League Baseball with the introduction of “torpedo bats,” a revolutionary design that has contributed to their explosive start in the 2025 season.

Torpedo bats feature a distinctive shape, with a thicker barrel positioned closer to the handle, resembling a torpedo or bowling pin. This design redistributes mass toward the area where hitters most frequently make contact, optimizing the “sweet spot” for better energy transfer and reduced vibration upon impact.

The mastermind of the torpedo bat is Aaron Leanhardt, an MIT-educated physicist and former University of Michigan professor. Leanhardt transitioned from academia to baseball, joining the Yankees’ coaching staff to apply scientific principles to the sport. His design aims to enhance hitting performance by aligning the bat’s mass with players’ contact points.

The Yankees’ adoption of torpedo bats has coincided with a remarkable offensive surge. In their opening series against the Milwaukee Brewers, the team hit a record-tying 15 home runs over three games, with nine of those homers coming from players using the new bat design.

Key players utilizing torpedo bats include:

• Jazz Chisholm Jr.: .417 AVG, 3 HR, 6 RBI
• Cody Bellinger: .400 AVG, 1 HR, 6 RBI
• Paul Goldschmidt: .417 AVG, 1 HR, 2 RBI
• Anthony Volpe: .167 AVG, 2 HR, 4 RBI
• Austin Wells: .200 AVG, 2 HR, 3 RBI

While some players, like Aaron Judge, have opted to stick with traditional bats, the overall impact of the torpedo bat on the team’s performance has been significant.

Despite initial skepticism, torpedo bats comply with MLB regulations, which stipulate that bats must be a smooth, round stick not more than 2.61 inches in diameter and not more than 42 inches in length. The success of the Yankees has prompted other players across the league to experiment with the design, indicating a potential shift in batting equipment standards.

The introduction of torpedo bats represents a fusion of science and sport, showcasing how innovative design can influence performance in baseball. As more players adopt this technology, it may herald a new era in batting strategy and equipment design.

Time to make bigger stadiums or perhaps double the size of the green monster!
