The rules for our Rookies, Coach Pitch, Minors, and Majors divisions are put together and maintained by AYS&B. For all other levels, AYS&B follows the rules of Eau Claire Babe Ruth and the Chippewa Valley Girls Fastpitch League (CVGFL).
If your bat does not feature the USA Baseball stamp it will not be allowed for use in league play. Big barrel bats, up to a 2-5/8" barrel that feature the new stamp will also be allowed.
Effective January 1, 2018, with the exception of the -3 bat (BBCOR certified), all other 2-1/4” and 2-5/8” minus factor bats (-5, -7, -8, etc.) must be certified with the USABat licensing stamp on the bat in order to be used for league and tournament play. 2-1/4” and 2-5/8” minus factor bats (-5, -7, -9, etc.) used in 2017 will be illegal to use.
Below are a few resources that detail the new bat rule:
