A leg spin bowler spins the ball from a right handed batsmans leg stump towards their off stump. The bowler grips the ball with the top joint of the index and middle fingers lying on the seam and the third finger bent along it.
As the bowlers arm moves forward the fingers are straightened and the wrist is flicked forwards, with the palm finishing facing downwards. The 3rd finger is the one that imparts most of the spin.
