Which rule governs the compliance of equipment used by players, such as bats?

The NFHS Equipment Compliance Rule specifically addresses the standards and regulations regarding the equipment that players are permitted to use during games, including bats. This rule ensures that all equipment meets the safety and performance standards set forth by the National Federation of State High School Associations, which is crucial for maintaining fairness and maintaining player safety on the field. By adhering to this rule, players and coaches can ensure that all equipment is appropriate for competition and complies with the specific guidelines laid out for high school baseball.

The other options focus on different aspects of the game. The NFHS Gameplay Standards primarily deal with the rules of play during competitions, while the NFHS Sportsmanship Code emphasizes the behavior and conduct expected from players and coaches. The NFHS Player Eligibility Rules are concerned with the criteria players must meet in order to participate in high school sports, such as age, residency, and enrollment status. Thus, the Equipment Compliance Rule is the most relevant and correct answer regarding the compliance of equipment used by players.
