Leg spin

Leg spin is a type of spin bowling in cricket. A leg spinner bowls right-arm with a wrist spin action. The leg spinner's normal delivery causes the ball to spin from right to left (from the bowler's perspective) when the ball bounces on the pitch. For a right-handed batsman, that is away from the leg side, and this is where it gets the name leg break.[1]

A leg spin or leg break delivery bowled from over the wicket.
A leg spin or leg break delivery bowled from around the wicket.

Leg spinners bowl mostly leg breaks, varying them by adjusting the line and length, and amount of side spin versus topspin of the deliveries. Leg spinners also typically use variations of flight by sometimes looping the ball in the air, allowing any cross-breeze and the aerodynamic effects of the spinning ball to cause the ball to dip and drift before bouncing and spinning or "turning", sharply. Leg spinners also bowl other types of delivery, which spin differently, such as the googly.

The terms 'leg spin', 'leg spinner', 'leg break' and 'leggie' are used in slightly different ways by different sources.

The bowlers with the second and fourth highest number of wickets in the history of Test cricket, Shane Warne and Anil Kumble, were leg spinners.[2] One famous example of leg spin is Warne's Ball of the Century.
