Which section would you study to understand obstruction and defensive interference penalties?

• A. Pitching, Substitutions, and Batting Order
• B. Scoring, Umpires, and Time
• C. Base Running, Interference, and Obstruction
• D. Fielding, Equipment, and Safety

Answer: (C)

Focus on where obstruction and defensive interference are covered in the rules. In NFHS Baseball Part II, these topics appear together in the Base Running, Interference, and Obstruction section. That section lays out what constitutes obstruction (when a fielder impedes a runner who doesn’t have the ball) and defensive interference (when a defender hinders a batter-runner or runner in a way that affects the play), and it explains the corresponding penalties and base awards. Because obstruction and defensive interference involve runners on base and the actions of fielders during live play, they’re grouped with base-running and related interference rules rather than in pitching, scoring, or safety-focused chapters. So studying that specific section is the best way to understand how these penalties are called and enforced.
