The USA Baseball bat standard (USABat), which applies to bats that are classified below the NCAA and NFHS level of play, was implemented on January 1, 2018.
Similar to the NCAA and NFHS BBCOR standard, which helped to eliminate discrepancies with different length bats and thus provide a more direct measure of bat performance, the USA Baseball bat standard establishes a wood-like performance standard for youth baseball bats, a standard that will provide for the long-term integrity of the game.
