What is the ruling when a player hits a home run but trips while rounding third base, and is assisted by the third-base coach?

In this scenario, the correct ruling is that the player is allowed to score the run despite receiving assistance while rounding third base. When a player hits a home run, they are generally entitled to complete their trip around the bases without penalty, even if they stumble or fall. The role of the third-base coach is to provide help and guidance, so if the player trips and that coach assists them in any minor way, it does not invalidate the run.

This ruling recognizes the nature of the play and the circumstances surrounding it—while outside assistance can lead to issues in other contexts, the crucial factor here is that the player was already in the process of scoring a home run. The home run is recognized as a completed play as long as the player legally touches all bases.

In this case, the assistance provided by the third-base coach does not classify as interference or a violation that would nullify the run. Therefore, the run counts, and the play is allowed to continue without any penalties being applied.
