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 (not applicable to the Senior Division) as well as Little League Challenger Division®, is that all current Little League-approved bats can no longer be used starting in 2018.
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®.
