    Little League Bats - Must be "USA Baseball" Certified

    This is a reminder to parents and players that all non-wood or laminated bats MUST display the "USA Baseball" certification logo (on the bat's handle) to be used in any Little League games or practices. 

    The only exceptions are in the Intermediate, Junior and Senior Divisions, for players age 13 to 16.

    Intermediate and Junior Divisions:  Bats with either the USA Baseball or BBCOR approved logos are permitted.

    Senior Division:  Non-wood bats must display the BBCOR certification logo. All bats must have a maximum -3 weight to length ratio (even if it's a solid one-piece wood bat).

    All Divisions:  Solid one-piece wood barrel bats are permitted without the USA Baseball logo in all divisions.

    Bats that are USSSA BPF 1.15 certified (used in 2017 and prior seasons) cannot be used in any games or practices.

    Length Restrictions:  USA Baseball-approved bats used in Rookie Ball Senior and above must be at least 27" long.

    USA Baseball-approved bats that are 26" and shorter are approved for use only with soft core (T Ball) baseballs, as indicated on the bat. These bats can only be used in the T Ball and Rookie Ball Junior divisions.
