When a runner misses third base while scoring, how must the defense handle the situation?

When a runner misses third base while scoring, the correct approach for the defense is to physically tag the runner. This action is crucial because the rules state that a runner is required to legally touch all bases in order for a run to count. If the defense is aware that the runner missed a base, they have the opportunity to appeal the missed base. Physically tagging the runner serves as a valid appeal, which can result in the runner being called out if the appeal is made properly.

The rationale behind this method is that it provides the defense with a tangible way to contest the run that could have potentially counted. Simply because the runner reaches home does not guarantee that the run will be considered valid if bases weren't legally touched. This method allows the game to be played fairly and according to the rules, maintaining the integrity of the sport.

Verbal appeals may not be sufficient in cases where physical evidence is shown that a rule was violated. Ignoring the situation or assuming a run counts just because the runner scores, despite missing a base, undermines the defensive team's right to enforce the rules. Stopping the game for an appeal is also not necessary as play can continue until the defense decides to make the appeal through a tag.
