NFHS Baseball Rules Book 2019
Rule 1 Section 3 Art.2c3 states, the bat shall have the following characteristics and components.
3. Not weigh, numerically, more than three ounces less than the length of the bat (e.g. a 33-inch-long bat cannot be less than 30 ounces).
The Rule Book also states, “In order to make NFHS rules skill-level and age-level appropriate, the rules may be modified by any organization that chooses to use them. Therefore, the MHSAA is modifying the bat rule for seventh and eighth graders only, to allow the bat not weigh, numerically, more than FIVE ounces less than the length of the bat. This policy goes into effect for this 2019 season. Please forward to all baseball officials in your association.
