 As fields get progressively more defensive, fielders will move out of the slip and gully area to cover more of the field, leading to 6–3 and 5–4 fields.If a bowler, usually a leg spin bowler, decides to attack the batsman's legs in an attempt to force a stumping, bowl him behind his legs, or induce a catch on the leg side, the field may stack 4–5 towards the leg side.It is unusual to see more than 5 fielders on the leg side, because of the restriction that there must be no more than two fielders placed behind square leg.
