For the Babe Ruth league page on bat rules go to:  

For the list of USA Bat Standard approved bats go to:  




  • If the illegal bat is discovered prior to a batter completing his "at bat" the bat is simply removed from play and the "at bat" continues.
  • A player who uses an illegal bat or non-conforming barrel dimension and hits a fair ball will be ruled out.  No advancement on the bases will be allowed, and any outs during the play shall stand.  This is an appeal play.  The "at bat" will be considered legal once a pitch is thrown to the next batter.
  • Any bat discovered prior to the game that does not conform to the above rule shall be directed to be removed immediately and not be allowed for use during the game. 

If you have any questions on approved or non-compliant bats, do not hesitate to contact Babe Ruth Headquarters.
