Bat Rules - Updated for 2018

New bat rules go into effect on 1/1/18

UpdatedSaturday January 6, 2018 byTLBR.


The TLBR league adopts the new USA Standard Babe Ruth International bat rule which specifies that bats must have the USA Baseball marking OR BBCOR .50.  Maximum barrel diameter of 2 5/8''.

. . . with the following local option limitations:

  • Maximum length/weight differential is 5 ("drop-5").
  • Maximum length is 34''

Wood barrel bats conforming to the specifications of Official Baseball Rule 1.10 are allowed.




Any player using a nonconforming bat will immediately be called out and the bat confiscated for the remainder of the game. Repeat offenses may result in suspension.
If you have any questions about the bat rule, or allowable bats, please contact a TLBR Board member.
