Important Bat Information from LLIUpdated Sunday March 25, 2018 by SLL.
The following information was obtained from Little League International's website
Little League® International has assembled an online resource page dedicated to baseball bat information, that includes the latest bat information, current Little League Baseball® rules and regulations governing bats, and a series of frequently asked questions.
As of January 1, 2018, the new USA Baseball Bat Standard was implemented. 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. Little League-approved baseball bats that were approved for use for the 2017 season will no longer be acceptable for use in any Little League game or activity as of January 1, 2018. For more information on the USABat standard and a complete list of bats approved through the USABat Standard, visit usabat.com.
Important Note: These changes only affect baseball divisions and don’t affect any divisions of softball.
