In Test and first-class cricket, to win you need to do two things: outscore your opponent and bowl them out twice. If you only manage to outscore them, but fail to cause their last innings to come to an end, the game will end in a draw, no matter how large your lead.
Are there any other sports where you need to achieve two different objectives like that within a set period of time (Or some other limitation on the duration of the game) to win, barring which it becomes a draw?
