2020 Bat Standards
All Player Pitch Divisions in SIYB must use USA Baseball Bats. Legal bats must have the USA Baseball Stamp on the bat or be a wood bat.
In conjunction with USA Baseball and its other participating national member organizations, SIYB 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 YBBCOR certified with the USABat licensing stamp on the bat in order to be used for league play.
All divisions (aside from coach pitch and tball) must follow the USA Bat Standards in 2020.
SIYB will still allow BPF 1.15 bat standards for all three of its tournaments: Cinco de Mayo, Memorial Day Super Bash, and Best in the Northwest.
