New Bat Rules for Little League baseball Beginning January 1, 2018

Posted by Murphy Ranch Little League on Oct 05 2017 at 09:31AM PDT in Fall 2017

As of January 1, 2018, Little League Baseball will implement the new USA Baseball Bat Standard. A “Bat Standard” is a measuring tool that is used within the bat manufacturing industry to ensure that all commercially available bats meet a certain performance level.

Little League approved baseball bats that were approved for the 2017 season will no longer be acceptable for the 2018 season. This new rule is mandatory for all Little League programs world-wide.

What you need to know…
Rule 1.10: The bat must be a baseball bat which meets the USA Baseball Bat standard (USABat) as adopted by Little League. It shall be a smooth, rounded stick, and made of wood or of material and color tested and proved acceptable to the USA Baseball Bat standard (USABat).

Beginning with the 2018 season, non-wood and laminated bats used in the Little League (Majors) and below, Intermediate (50-70) Division, and Junior League divisions shall bear the USA Baseball logo signifying that the bat meets the USABat – USA Baseball’s Youth Bat Performance Standard. All BPF – 1.15 bats will be prohibited beginning with the 2018 season. Additionally, starting in 2018, the bat diameter shall not exceed 2⅝ inches for these divisions of play.
