What is the correct sequence for whistling for a serve?

The correct sequence for signaling a serve is to extend the arm first, followed by whistling, and then beckoning the server to proceed.

This order is important for ensuring a clear and organized communication with the players. By extending the arm first, the official is indicating readiness and that they are about to signal for the serve. Whistling serves as the auditory signal that the serve can begin, while beckoning afterward directs the player to take their serve, confirming that they have the go-ahead.

This sequence helps maintain the flow of the game, allowing players to understand when they can serve without any ambiguity. The clarity in signaling also assists in maintaining proper officiating standards. In this context, other sequences would confuse players about when to initiate the serve, which could disrupt the rhythm of the game.
