Doube base question

[Dave9819]

ASA rules:

Batter hits ground ball to infielder. Infielder throws the ball to first base. The runner beats the throw, but uses the white portion of the double base. I know the rule states that the defense must appeal that the runner used the white portion of the base prior to the runner returning to the base. Does the appeal by the defense have to come from the players on the field, or could one of the coaches appeal that as well?
