USA Baseball Bat Standard
Baseball Bat 2018 Rule Change
Updated Monday January 22, 2018 by Kelsey Clements.
As of January 1, 2018 Little League® will require the new USA Baseball Standard be implemented. Little League-approved baseball bats approved for use for the 2017 season will no longer be acceptable for use in any Little League game or activity starting on January 1, 2018.
Rule 1.10 - Baseball
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, Junior League divisions, and Challenger division 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. Additional information is available at LittleLeague.org/batinfo.
Under the USABat standard, certified Tee Ball bats (26" and shorter) will feature the USA Baseball mark and text which reads ONLY FOR USE WITH APPROVED TEE BALLS. All Tee Ball bats must feature the USA Baseball mark and accompanying text. Tee Ball bats that were produced and/or purchased prior to the implementation of the new standard can be certified using an Approved Tee Ball Sticker via the USA Baseball Tee Ball Sticker Program (USABaseballShop.com) beginning September 1, 2017.
It shall not be more than 33 inches in length; nor more than 2⅝ inches in diameter, and if wood, not less than fifteen-sixteenths (15/16) inches in diameter (7/8 inch for bats less than 30") at its smallest part. Wood bats taped or fitted with a sleeve may not exceed sixteen (16) inches from the small end.
NOTE: Solid one-piece wood barrel bats do not require a USA Baseball logo.
An illegal or altered bat must be removed.
In all divisions, non-wood bat must have a grip of cork, tape, or composition material, and must extend a minimum of 10 inches from the small end. Slippery tape or similar material is prohibited.
NOTE 1: The traditional batting donut is not permissible.
NOTE 2: The use of pine tar or any other similar adhesive substance is prohibited at all levels of Little League Baseball and Softball. Use of these substances will result in the bat being declared illegal and removed from play.
NOTE 3: Non-wood bats may develop dents from time to time. Bats that have cracks or sharp edges, or that cannot pass through the approved Little League bat ring for the appropriate division must be removed from play. The 2¼-inch bat ring must be used for bats labeled 2¼. The 2⅝-inch bat ring must be used for bats labeled for 2⅝.
NOTE 4: An illegal bat must be removed. Any bat that has been altered shall be removed from play. PENALTY - See Rule - 6.06(d).
