Which signal indicates a foul ball or a dead ball?

The signal that indicates a foul ball or a dead ball is represented by both hands open above the head. This gesture serves as a clear communication tool for umpires to indicate to players, coaches, and spectators that the ball is no longer in play due to a foul or that a dead ball situation has occurred.

When the umpire raises both hands with open palms, it draws attention and helps ensure that everyone is aware of the stoppage in play. This signal is important in maintaining the flow of the game, as it clearly communicates significant moments such as when a ball goes out of play or when an additional ruling is needed.

The specificity of this signal helps to distinguish it from other calls, minimizing confusion during the game. Understanding the appropriate signals used in baseball is crucial for umpires to manage the game effectively and maintain clear communication with all participants.
