In conjunction with USA Baseball and its other participating national member organizations, PONY Baseball has adopted the new USA Baseball bat standard (USABat). Effective January 1, 2018, with the exception of -3 (BBCOR certified), all other minus factor bats (-5, -7, -9, etc.), must be USABat certified with the USABat licensing stamp on the bat in order to be used for league and tournament play. Minus factor bats -5, -7, -9, etc. used in 2017 will be illegal to use in 2018.

For the 2018 Spring Baseball Season, Fountain Valley Pony Baseball suggests you use the new USA Baseball Standard bats for the season but will not be making it mandatory. The new Pony bat rule will be mandatory for post-season play (All-Stars). Beginning in the 2018 Summer Baseball Season, the new USA Bat Standard will be enforced.
