New Bat Rules for 2018
Existing composite and aluminum youth bats will not be legal for Little League play after the Fall 2017 season. The new rule is aligned with the high school and college bat rules, which create a more ‘wood-like’ performance standard. Wood bats and high school level bats are not impacted.
For Junior League Baseball divisions and below, as well as all Challenger divisions, 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).
Little League and USABat have released a list of bat suppliers that are approved: https://usabat.com/
