DHYS Bat Rules – Effective September 2017
********
NOTE: Beginning January 1, 2018, USA Baseball will implement a new method for measuring bat performance in the testing of youth baseball bats. The new "USA Bat Standard" will create wood-like performance in youth baseball bats. Beginning September 1, 2017, bat companies will sell bats that meet the new standard. Beginning in the fall season of 2018 the new bat rules will apply to DHYS and USSSA 1.15 BPF bats will no longer be allowed.
