A bat would be considered legal for the game if which of the following marks is present?

• A. BBCOR certification mark.
• B. BESR certification mark.
• C. The temperature of the bat had been artificially controlled.
• D. It had been altered from the manufacturer's original design and production.

Answer: (A)

In current play, bats must carry a certification mark that shows they meet the approved performance standard. The BBCOR certification mark indicates the bat has been tested and certified to the BBCOR limit for the batted-ball coefficient of restitution, which standardizes safety and performance for NFHS/WVSSAC games. A bat with this mark is legal because it has been approved under the current standard. The BESR mark comes from an older standard and is not acceptable today, so a bat with that mark would not be legal. Temperature adjustments or altering the bat from its original design also violate the rules and would not make a bat legal, even if it had a mark.
