What rule does the NCAA follow to decide if a ball is fair or foul?

The NCAA follows a rule that dictates a ball is fair if it lands in the field of play before the foul lines. This means that any batted ball must first touch the ground in the fair territory, which is designated by the foul lines extending from home plate to the outfield. Specifically, if the ball lands between the foul lines and is subsequently in play, it is considered fair. This rule is foundational in determining the status of a ball during gameplay and aligns with the principles of the game, allowing for fair play and competitive integrity.

The other options do not accurately encapsulate the criteria for fair or foul balls as recognized by the NCAA rules. For instance, a ball that is hit into the stands can be either fair or foul depending on where it was hit; simply being in the stands does not determine its status. Similarly, a ball rolling past the pitcher's mound does not inherently determine its fair or foul status, and the position of the ball after passing the last base is also not relevant in terms of determining whether the ball is considered fair or foul. The emphasis on where the ball lands before the foul lines is crucial to following the rules of play in NCAA Softball.
