Important news for parents looking to purchase baseball bats for 2017. Little League and USA baseball are implementing a new standard (USABat) for bats at the youth levels next year in 2018. This standard will create wood-like performance in youth bats, which is less than the performance of current bats on the market.
Please know all of the current legal composite / metal / aluminum bats available in the stores today will not be legal in 2018. Bats that are regulated by the new USABat standard will be available to purchase by September 1st, 2017.
Through 2017, Little League will require the use of a 2 1/4 inch diameter barrel on all of their bats for youth baseball players. Starting 2018 , the new USABat standard will allow for bats with either a 2 1/4 inch or 2 5/8 inch barrel diameter (as long as they carry the new USABat stamp). One thing to keep in mind, however, is the sweet spot will be much smaller on the new bats than the sweet spot on the current big barrel bats available on the market.
USSSA Baseball (NVTBL Travel Baseball) will not be affected by the USABat standard, so bats will still be produced with the USSSA BPF 1.15 certification. Little League will require the USABat "Stamp" certification.
