During a game, if an umpire is certain a fly ball is foul but another umpire signals it a home run, what should the plate umpire do?

In this scenario, the plate umpire should consult with the third-base umpire (U3) to clarify the situation. When two umpires have conflicting calls, it is essential to resolve the discrepancy through communication. The plate umpire has the authority to seek clarification without a formal request if they feel that the other umpire's judgment needs to be evaluated due to the certainty of the foul ball.

This course of action ensures that the right decision is made based on collaboration and the rules of the game. It is important for umpires to communicate effectively to maintain the integrity of the game and to provide fair outcomes. Each umpire has a unique perspective, and consulting with U3 allows them to utilize that perspective to arrive at the correct resolution.

Continuing to play without addressing the conflicting calls could lead to further confusion and potential disputes among players and coaches, which is why a collaborative review is essential in this case.
