2018 Bat Size Changes

Updated Thursday January 25, 2018 by Stephanie McMurray.

Effective on January 1, 2018, Little League Baseball® moved to the new USABat standard which means all bats must be marked with the USABat label as shown in the picture below. 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. All bats marked with BFP 1.15 will not be permitted to be used in any Little League Activities, including practices or games. For more information on the USABat standard and a complete list of bats approved through the USABat Standard, visit usabat.comAdditionally, starting in 2018, the bat diameter shall not exceed 2 inches for Little League (Majors) and below. Additional information is available at LittleLeague.org/batinfo.

Tee Ball:

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. Also, please refer to the attached for more information.

Minor/Major Divisions:

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.
