1. Judging a Wide
(a) If the bowler bowls a ball, not being a No ball, the umpire shall adjudge it a Wide if, according to the definition in (b) below, in his opinion the ball passes wide of the striker where he is standing and would also have passed wide of him standing in a normal guard position.
(b) The ball will be considered as passing wide of the striker unless it is sufficiently within his reach for him to be able to hit it with his bat by means of a normal cricket stroke.
2. Delivery not a Wide
The umpire shall not adjudge a delivery as being a Wide
(a) if the striker, by moving,
either (i) causes the ball to pass wide of him, as defined in 1(b) above
or (ii) brings the ball sufficiently within his reach to be able to hit it with his bat by means of a normal cricket stroke.
(b) if the ball touches the striker's bat or person.
