Stumped is a method of dismissing a batsman in cricket, which involves the wicket-keeper putting down the wicket while the batsman is out of his ground. (The batsman leaves his ground when he has moved down the pitch beyond the popping crease, usually in an attempt to hit the ball). The action of stumping can only be performed by a wicket-keeper, and can only occur from a legitimate delivery (i.e. not a no-ball), while the batsman is not attempting a run; it is a special case of a run out.
