30.1 When out of his/her ground
30.1.1 A batter shall be considered to be out of his/her ground unless some part of his/her person or bat is grounded behind the popping crease at that end.
30.1.2 However, a batter shall not be considered to be out of his/her ground if, in running or diving towards his/her ground and beyond, and having grounded some part of his/her person or bat beyond the popping crease, there is subsequent loss of contact between the ground and any part of his/her person or bat, or between the bat and person.
30.2 Which is a batter’s ground
30.2.1 If only one batter is within a ground, it is his/her ground and will remain so even if he/she is later joined there by the other batter.
30.2.2 If both batters are in the same ground and one of them subsequently leaves it, the ground belongs to the batter who remains in it.
30.2.3 If there is no batter in either ground, then each ground belongs to whichever batter is nearer to it, or, if the batters are level, to whichever batter was nearer to it immediately prior to their drawing level.
30.2.4 If a ground belongs to one batter then, unless there is a striker who has a runner, the other ground belongs to the other batter, irrespective of his/her position.
30.2.5 When a batter who has a runner is striker, his/her ground is always at the wicket-keeper’s end. However, 30.2.1, 30.2.2, 30.2.3 and 30.2.4 will still apply, but only to the runner and the non-striker, so that that ground will also belong to either the non-striker or the runner, as the case may be.
30.3 Position of non-striker
The non-striker, when standing at the bowler’s end, should be positioned on the opposite side of the wicket to that from which the ball is being delivered, unless a request to do otherwise is granted by the umpire.
