The emerald ash weevil strikes ash bats in Major League Baseball

Imagine a baseball season without the iconic crack of an ash bat. This could be a reality thanks to Agrilus planipennis, a small beetle that is causing massive destruction of ash trees across North America.

For decades, ash has reigned supreme in baseball bats. From legendary players like Babe Ruth to modern hitters like Mark McGwire, ash has been the material of choice for its feel and performance. Companies like Hillerich & Bradsby, makers of Louisville Slugger, churned out hundreds of thousands of ash bats each year.

However, the emerald ash borer has changed the game. This invasive insect, about the size of a grain of rice, attacks ash trees by laying eggs under the bark. The larvae then feed on the tree’s vital nutrients, eventually killing it. Since arriving in the United States in 2002, the ash borer has spread rapidly, leaving a trail of dead and dying ash trees in its wake.

The impact on baseball has been rapid. Finding quality ash lumber is becoming increasingly difficult. Companies like Hillerich & Bradsby have had to adapt, now producing mostly low-end ash bats for occasional use. Major League Baseball players, once loyal to ash, have switched to maple bats, which offer advantages in hardness and consistency.

The future of ash in baseball looks grim. Even if scientists could control agrilus planipennis, it would take generations for ash trees to recover. While other woods like birch are being explored, they have yet to capture the hearts (or ears) of players.

This change marks the end of an era for baseball. The sound of the ash bat hitting the ball, a sound synonymous with the game for so long, may be gone. The future of baseball bats belongs to maple, for now, leaving ash bats as a relic of a bygone era.
