USA Baseball Bat Standard: Frequently Asked Questions

Last Updated on December 13, 2017

USA Baseball

Testing and evaluating of youth baseball bats has evolved into a science. So much so that the standard has also evolved to where USA Baseball, the national governing body for the sport of baseball in the United States, is adopting a new method for measuring bat performance in the testing of youth bats that will go into effect on January 1, 2018. The new USA Baseball bat standard (USABat), was developed by a USA Baseball committee of scientific experts.

Effective on January 1, 2018, Little League Baseball® will adhere to the new USABat standard. No bats previously approved for use in Little League Play (Junior League Baseball and below) will be permitted to be used in any Little League game or practice, or other Little League function, event, or activity. For more information on the USABat standard and a complete list of bats approved through the USABat Standard, visit usabat.com.

What this means for local Little Leagues, and Little League baseball players in the Tee Ball through Junior League Divisions, as well as Little League Challenger Division®, is that all current Little League-approved bats can be used during the 2017 Little League regular season and throughout tournament play, but can no longer be used starting in 2018. All of Little League’s current bat regulations will remain in effect until December 31, 2017. Be aware that this new bat standard effects Little League Baseball only. There are no changes to the bat standard or regulations for Little League Softball®.

The new “approved” USABat label is as follows...
