Legal Bats

Baseball Bat Rule

Beginning January 1, 2012, all bats not made of a single piece of wood shall meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard, and such bats shall be labeled with a silkscreen or other permanent certification mark. The certification mark shall be rectangular, a minimum of a half-inch on each side and located on the barrel of the bat in any contrasting color. Aluminum and composite bats shall be labeled as approved tamper evident, and be marked as to being aluminum or composite. This marking shall be silkscreen or other permanent certification mark, a minimum of one-half-inch on each side and located on the barrel of the bat in any contrasting color.

A bat without the BBCOR marking is illegal for use in games or practices. Coaches are responsible for making sure all bats meet the NFHS standard.

Bats that are altered from the manufacturer’s original design and production, or that do not meet the rule specifications, are illegal (See 7-4-1a). No foreign substance may be inserted into the bat. Bats that are broken, cracked or dented or that deface the ball, i.e., tear the ball, shall be removed without penalty. A bat that continually discolors the ball may be removed from the game with no penalty at the discretion of the umpire.M.

Rationale: Recent bat products have circumvented the intent and spirit of the current rule. Improvements in science and technology now allow this change that will require bats to be within performance limits during the life of the bat. In addition, this change will minimize the ability for the bat to be tampered or altered.
