Bat Rule Updated: 2/1/18
FMYSA will permit the usage of bats that meet USSSA and USA bat standards. Along with these, we will also continue using the BBCOR bats. Please see the following explanation and guidelines for USSSA, USA, and BBCOR bat standards.
USSSA bat standard: USSSA has a formal 1.15 BPF standard for baseball bats used in 14U and below (allowing diameters of up to 2 ¾"). FMYSA will continue to allow the use of these bats in all FMYSA sanctioned events in 14U and below.
USA bat standard: The new USA baseball bat standard (USABat) applies to bats that are classified below the NCAA and NFHS level of play. This was implemented January 1, 2018. All bats used in Little League, Babe Ruth & Cal Ripken, PONY, Dixie or AABC will only accept bats stamped with the USA Baseball stamp. All players 14U and below must have 2-5/8" barrels and be marked with the USABat stamp. This new bat standard has created a new "wood-like" response in aluminum bats.
BBCOR (Bat-Ball Coefficient of Restitution): BBCOR is the standard currently governing adult bats used in high school and collegiate baseball play. BBCOR measures the trampoline effect of the bat. All BBCOR bats carry the "BBCOR Certified .50" mark on the bat. These bats must carry a length to weight ratio that is no greater than -3 and a barrel diameter that does not exceed 2 -5/8".
FMYSA will permit usage of USSSA and USABat for play 14U and under. BBCOR certified bats are required for play 15U and above. This applies to all bats used during play of all events sanctioned by FMYSA.
