USA Bat Standard (Little League)

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. The new bat standard effects Little League Baseball only. There are NO changes to the bat standard or regulations for Little League Softball.

One of the stamps below must be on the bat in order for it to be legal in 2018.

Travel Organizations are NOT adopting the USA Bat Standard. They will continue to use the 1.15 BPF Bat Standard.


USA Baseball believes that a wood-like performance standard will best provide for the long-term integrity of the game. The new bats will be designed to perform much like wood and BBCOR bats.

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.

Which national member organizations are implementing this new standard?

Along with Little League Baseball®, the following organizations are participating (in alphabetical order): American Amateur Baseball Congress (AABC), Babe Ruth Baseball/Cal Ripken Baseball, Dixie Youth Baseball, and PONY Baseball.
