Leg spin

Leg spin is a type of spin bowling in the sport of cricket. A leg spinner bowls right-arm with a wrist spin action, causing the ball to spin from right to left in the cricket pitch, at the point of delivery. When the ball bounces, the spin causes the ball to deviate sharply from right to left, that is, away from the leg side of a right-handed batsman. The same kind of trajectory, which spins from right to left on pitching, when performed by a left-arm bowler is known as left-arm orthodox spin bowling.

As with all spinners, leg spinners bowl the ball far slower (70–90 km/h or 45–55 mph) than fast bowlers. The fastest leg spinners will sometimes top 100 km/h (60 mph). Leg spinners 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 (usually called "turning") sharply. While very difficult to bowl accurately, good leg spin is considered one of the most threatening types of bowling to bat against, since the flight and sharp turn make the ball's movement extremely hard to read and the turn away from the batsman (assuming he or she is right-handed) is more dangerous than the turn into the batsman generated by an off spinner.
