Leg spin

From Cricipedia

Leg Spin is a style of spin bowling in cricket. A leg spinner bowls right-arm with a wrist spin action, causing the ball to spin anti-clockwise at the point of delivery. When the ball bounces, the spin causes the ball to deviate sharply from right to left (as seen by the bowler) — that is, away from the leg side of a right-handed batsman, which is the origin of the name "leg spin". The same action when performed by a left-arm bowler is known as left-arm unorthodox spin or "chinaman" bowling.
