  • Cricket jargon - a team declares when they voluntarily end an innings. Such an act is a declaration. Usually a declaration is made because a team considers it has an adequate lead in runs and wishes to save time in the game. Sometimes declarations are made to throw open a game that would otherwise be heading for a draw.
