If a base umpire calls R1 safe while the plate umpire calls R1 out, what will happen?

In this situation, the correct course of action is to uphold the base umpire's call after consultation. This scenario arises under specific guidelines set forth in baseball rules, where it is acknowledged that umpires may have differing perspectives on a play. The base umpire’s proximity to the play gives them a clearer view of the situation regarding R1's status on the base.

Consultation among the umpires aims to clarify and ensure that the most accurate decision is rendered based on their observations and interpretations. If it is determined that the base umpire had a better view and a more accurate call regarding R1’s safe status, then that call will stand. This approach maintains the integrity of the game by respecting the judgment of the umpire closest to the action.

The other options generally do not address the umpires' authority and process effectively. For instance, while appeals may be a part of gameplay, they do not apply in this case where two officials have made conflicting calls. The emphasis on precedence from the plate umpire doesn't hold as both umpires serve distinct roles and neither automatically supersedes the other without consultation. Lastly, playing under protest would be unnecessary if the umpires can resolve the disagreement through conversation and uphold the call.
