High School Baseball Umpire Practice Exam 2026 - Free Umpiring Practice Questions and Study Guide

Interference in baseball occurs when a player's actions disrupt the normal course of play, and option C describes a situation where a player’s equipment unintentionally causes a play to be disrupted. This can include instances such as a player's helmet or bat inadvertently impacting a fielder's ability to make a play, ultimately affecting the outcome of the game.

This is an important aspect of the game as it emphasizes the responsibility players have to manage their equipment during play, similar to how players must maintain awareness of their actions to avoid interfering with other players. Understanding this definition of interference helps umpires make appropriate decisions during games, ensuring fair play and maintaining the integrity of the game.

In contrast, stepping out of the box does not disrupt the play while the pitch is being executed; obstruction is more specific and relates to the actions of a fielder rather than a player’s equipment; and taking too many steps by the pitcher pertains to a violation of the rules regarding the pitching stance, which is not classified as interference.
