Left-arm orthodox spin

Left-arm orthodox spin, Left-arm off spin also known as slow left-arm orthodox spin bowling, is a type of left-arm finger spin bowling in the sport of cricket.[1] Left-arm orthodox spin is bowled by a left-arm bowler using the fingers to spin the ball from right to left of the cricket pitch (from the bowler's perspective).

Left arm orthodox spin bowlers generally attempt to drift the ball in the air into a right-handed batsman, and then turn it away from the batsman (towards off-stump) upon landing on the pitch. The drift and turn in the air are attacking techniques. The stock delivery of a left-arm orthodox spin bowler is the left-arm orthodox spinner.[2]

The major variations of a left-arm orthodox spin bowler are the topspinner (which turns less and bounces higher in the cricket pitch), the arm ball (which does not turn at all, drifts into a right-handed batsman in the direction of the bowler's arm movement; also called a 'floater') and the left-arm spinner's version of a doosra (which turns the other way).
