Testing and evaluating of youth baseball bats has evolved into a science. So much so that the standard has also evolved to where USA Baseball, the national governing body for the sport of baseball in the United States, is adopting a new method for measuring bat performance in the testing of youth bats that will go into effect on January 1, 2018. The new USA Baseball bat standard (USABat), was developed by a USA Baseball committee of scientific experts.
Effective on January 1, 2018, Little League Baseball® will adhere to the new USABat standard. No bats previously approved for use in Little League play (Junior League Baseball and below) will be permitted to be used in any Little League game or practice, or other Little League function, event, or activity. As of January 1, 2018, USABat Standard bats must be used in the Little League Major Baseball Division and below. Either USABat Standard bats or BBCOR bats must be used at the Intermediate (50/70) Baseball and Junior League Baseball Divisions. At the Senior League Baseball Division, all bats must be meet the BBCOR standard.For more information on the USABat standard and a complete list of bats approved through the USABat Standard, visit usabat.com.
Be aware that this new bat standard effects Little League Baseball only. There are no changes to the bat standard or regulations for Little League Softball®.
