The BBCOR (Batted Ball Coefficient of Restitution) standard is a set of rules that govern the performance of baseball bats used in high school and college baseball in the United States. Bats that meet the BBCOR standard are designed to reduce the trampoline effect, which is the tendency of a bat to propel a baseball farther than it would if it were hit with a bat that does not meet the standard. The new BBCOR bats for 2025 are designed to further reduce the trampoline effect and improve the safety of the game.
The new BBCOR bats for 2025 are made with a variety of new materials and technologies that are designed to reduce the trampoline effect. One of the most significant changes is the use of a new alloy that is stronger and more durable than the alloys used in previous BBCOR bats. This new alloy allows the bats to be made with thinner walls, which reduces the trampoline effect. In addition, the new bats feature a new design that helps to disperse the energy of the ball on impact, which also reduces the trampoline effect.
