Starting in 2018, Little League® International Board of Directors will formally adopt USA Baseball’s new standard for bat performance testing. Developed by a USA Baseball committee of scientific experts, Little League Baseball® has decided to adopt the new bat standard for mandated use effective January 1, 2018. Little League-approved bats can be used through December 31, 2017, and all current bat regulations will be in effect until then. That includes the moratorium prohibiting the use of all 2 ¼ inch barrel baseball bats constructed with composite material in the barrel, unless approved.
