Major League Baseball has no shortage of storylines to open the 2025 season, but none are stirring more debate than introducing the so-called “torpedo” bat. The innovative design has already made an impact, with the New York Yankees, early adopters of the bats, matching an MLB record by smashing nine home runs in their first three games.
Aaron Leanhardt, a Miami Marlins field coordinator, created the bats. Before this season, he was relatively unknown. Now, he’s at the center of controversy as MLB debates allowing the bats. Speaking publicly for the first time, he stayed humble. He deflected praise back to the players.
The Science Behind The Swing

Leanhardt’s torpedo bat alters the traditional weight distribution, shifting mass toward the center rather than the end of the bat. The effect? It’s a more balanced swing with potentially more power. While MLB rules technically permit the bats, their rapid success has sparked debate among players, coaches, and analysts.
“There’s a lot more cameras here today than I’m used to. It’s definitely been surreal for the last couple of days,” Leanhardt said ahead of the Marlins’ matchup against the Mets on Monday. “At the end of the day, it’s about the batter and not the bat. It’s about the hitters and their hitting coaches, not their hitting implement.”

Despite the attention, Leanhardt downplayed his role in the breakthrough, emphasizing that the innovation was born from hitters questioning their own performance. “You show up every day, put on the glove you’re given, swing the bat that you’re given, put on the spikes you’re given. And you go about your day as best you can. Every now and then, it takes a little bit of time to question what you’re doing,” he explained.
