In the spring of 2025, baseball fans were treated to a surprise when the New York Yankees began the season with a unique style of bat.

Dan Russell from Pennsylvania State University presented his acoustic analysis of torpedo bats at the 190th Meeting of the Acoustical Society of America, running May 11–15.
