Spin bowling
Spin bowling is a bowling technique in cricket, in which the ball is delivered relatively slowly but with rapid rotation, giving it the potential to deviate sharply after bouncing. A bowler who uses this technique is called a spinner, a spin bowler, or a slow bowler.
It is one of the two main approaches to bowling, the other being fast bowling.
A spinner may bowl with their right-arm or left-arm, and with a finger spin or wrist spin action. Therefore, there are four types of spin bowling: off spin, leg spin, left-arm orthodox spin and left-arm unorthodox spin.
The bowlers with the highest, second-highest and fourth-highest number of wickets in the history of Test cricket, Muttiah Muralitharan, Shane Warne and Anil Kumble, respectively, were spinners.
The main aim of spin bowling is to bowl the cricket ball with rapid rotation so that when it bounces on the pitch it will deviate from its normal straight path, thus making it difficult for the batsman to hit the ball cleanly. The speed the ball travels is not critical, and is significantly slower than that for fast bowling. A typical spin delivery has a speed in the range 70–90 km/h (45–55 mph).
Spin bowling is divided into four categories, depending on the physical technique used. There is virtually no overlap between the two basic biomechanical techniques of wrist spin and finger spin.
Depending on technique, a spin bowler uses either predominant wrist or finger motion to impart spin to the ball around a horizontal axis that is at an oblique angle to the length of the pitch. This sort of spin means it is also possible for the Magnus effect to cause the ball to deviate sideways through the air, before it bounces. Such deviation is called drift. The combination of drift and spin can make the ball's trajectory complex, with a change of direction at the bounce.
Spin bowlers are generally given the task of bowling with an old, worn cricket ball. A new cricket ball better suits the techniques of fast bowling than spin bowling, while a worn one grips the pitch better and achieves greater spin. Spin bowlers are also more effective later in a game, as the pitch dries up and begins to crack and crumble. This again provides more purchase for the spinning ball and produces greater deviation. Spin bowlers that open the bowling are rare, but became a more viable option with the introduction of Twenty20 cricket when pitch conditions are in their favour, and the ball also generally drifts more in the air. Spin bowlers can also be used tactically in shorter forms of the game, to 'take the pace off the ball'. This strategy is especially effective to slow down the scoring rates of batsmen who specialise in making use of the pace of faster bowlers to score runs quickly. The lower inherent momentum of a spin bowler necessitates more power exerted by the batsman to achieve the same results.
