Which section would you consult for rules about defensive interference during a running play?

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

Answer: (B)

When a run is in progress and the question involves what the defense can or cannot do to a baserunner, you turn to the section that handles base running, interference, and obstruction. This part of the rulebook covers how runners advance, what counts as defensive interference, and how plays are ruled when interference occurs. It’s the most relevant place because it specifically addresses running plays and the actions that can affect a runner’s advancement.

The other sections focus on different areas: pitching, substitutions, and batting order deal with pitcher rules and lineup changes; scoring, umpires, and time covers how plays are scored and umpire procedures; fielding, equipment, and safety addresses defensive fielding and equipment. None of these concentrate on the interference rules during running plays like the base running section does.
