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 when the ball bounces on the pitch. For a right-handed batter, that is away from the leg side, and this is where it gets the name leg break.

Spin bowling is a bowling technique in cricket, in which the ball is delivered relatively slowly but with the potential to deviate sharply after bouncing. The bowler is referred to as a spinner.
