USA Baseball Bat Standard

In conjunction with USA Baseball and its other participating national member organizations, Dizzy Dean, Little League, Cal Ripken, and PONY Baseball have adopted the new USA Baseball bat standard (USABat). Effective January 1, 2018, with the exception of -3 (BBCOR certified), all other 2 1/4" and 2 5/8" barrel bats with a minus factor of (-5, -7, -9, etc.), must be USABat certified with the USABat licensing stamp on the bat in order to be used for league and tournament play. All 2 1/4" and 2 5/8" minus factor bats -5, -7, -9, etc. used in 2017 will be illegal to use in 2018.

Tee ball bats are not required to undergo lab testing to receive approval under the USABat program. However, to be approved for play, tee ball bats must carry the USA Baseball mark accompanied by the following text: "Only For Use With Approved Tee Ball Bats." If you already have a tee ball bat you would like to continue using, all you have to do is purchase a USA Bat sticker directly from USA Baseball and place it on your bat. You can purchase a USA Bat sticker, click here. Tee ball bats manufactured after the new rule was adopted will already include the USABat Baseball mark. 


All new bats that bear the USABat licensing mark will be permissible for play in the leagues and tournaments of the participating youth baseball organizations.


So why the change to a wood-like standard? USA Baseball's national member organizations believe that a wood-like performance standard will best provide for the long-term integrity of the game. However, wood is a scarce resource. The new bats will be designed to perform much like wood, where its performance will be limited to the highest performing wood.
