The Yankee Torpedo
Jeff Passan, for ESPN:
An MIT-educated physics professor at the University of Michigan for seven years, [Aaron] Leanhardt left academia for athletics specifically to solve these sorts of problems. And as he spoke with more players, the framework of a solution began to reveal itself. With strikeouts at an all-time high, hitters wanted to counter that by making more contact. And the easiest way to do so, Leanhardt surmised, was to increase the size of the barrel on their bat.
Elongating the barrel – the fat part of the bat that generates the hardest and most contact – sounded great in theory. Doing so in practice, though, would increase the weight of the bat and slow down swing speed, negating the gains a larger sweet spot would provide. […]
The creation of the bowling pin bat (also known as the torpedo bat) optimizes the most important tool in baseball by redistributing weight from the end of the bat toward the area 6 to 7 inches below its tip, where major league players typically strike the ball. Doing so takes an apparatus that for generations has looked the same and gives it a fun-house-mirror makeover, with the fat part of the bat more toward the handle and the end tapering toward a smaller diameter, like a bowling pin.
There was much controversy about these bats over the weekend, certainly because this story involves the Yankees. But, these bats are entirely within the letter and the spirit of MLB’s bat regulations. I love seeing clever innovations in such an old game.
