USA BAT RULES
USA Baseball, the national governing body for the sport of baseball in the U.S., in conjunction with participating national member organizations announced today the decision to adopt a new method for measuring bat performance in the testing of youth bats. Informed by the research of leading scientists on the USA Baseball Bat Study Committee, and supported by its NMOs, -- including the American Amateur Baseball Congress (AABC), Amateur Athletic Union (AAU), Babe Ruth Baseball/Cal Ripken Baseball, Dixie Youth Baseball, Little League Baseball and PONY Baseball -- USA Baseball has concluded that recent advancements in science, engineering, technology, and the materials available to fabricate non-wood bats, now allow the manufacturers to construct youth bats that can perform at a wood-like level through the entire range of lengths and weights of youth bats.
Bat manufacturers will be making the new USA Baseball Approved bats available to the public in the Fall of 2017. Only bats with the stamp below will be approved for play in Little League during the 2018 season and beyond.
