Major League Baseball (MLB) maintains strict regulations regarding equipment, including the bats used by players. The league periodically reviews and updates these standards, sometimes leading to changes in approved bat manufacturers and models. A shift in the officially sanctioned bat for a given season can significantly impact player performance and game dynamics. For example, adjustments to bat composition or design can influence bat speed, exit velocity, and the overall balance of offense and defense within the game.
The selection process for approved bats involves rigorous testing and evaluation to ensure fairness, safety, and adherence to specific performance criteria. Historical shifts in approved bats have often reflected advancements in materials science and engineering, with a focus on enhancing both player performance and safety standards. These changes can influence the strategies employed by both hitters and pitchers, ultimately shaping the evolution of the game itself. Understanding the history and rationale behind bat regulations provides valuable context for appreciating their impact.
