Spin bowling is a bowling technique in cricket and a bowler is referred to as spinner .

Destination

The main purpose of spin bowling is to wet the ball of cricket with rapid rotation so that when bouncing on the field it will deviate from its normal straight line, making it difficult for the batsman to hit the ball cleanly. The speed of the running ball is not important, and significantly slower than that for fast bowling. The typical spin delivery has a speed in the range of 70-90 km/h (45-55 mph). However, in 2010 Shahid Afridi of Pakistan launched the fastest round of delivery of 134 × km/h in a T20 match against New Zealand

Technique

Spin bowling is divided into four different categories, depending on the particular physical technique used. There is almost no overlap between the two basic biomechanical techniques of the wrist and the rotation of the fingers.

• Rest - Right hand with finger spin technique. (eg Muttiah Muralitharan, Ravichandran Ashwin, Nathan Lyon)
• Left hand orthodox rotation - Left hand with rotating finger technique. (eg Daniel Vettori, Rangana Herath, Shakib Al Hasan)
• Rest legs - Right hand with wrist technique. (eg Shane Warne, Anil Kumble, Shahid Afridi)
• Unusual left rotation - Left with wrist technique. (eg Brad Hogg, Paul Adams, Chuck Fleetwood-Smith)

Depending on the technique, the spin bowler uses the dominant finger or finger movement to give a spin to the ball around the horizontal axis that is at an angle to the pitch length. This sort of spin is also possible for the Magnus effect causing the ball to deviate sideways through the air, before bouncing. Such deviations are called drift . The combination of drift and spin can make the ball trajectory complex, with a change of direction on the bounce.

These trajectories can be achieved by a bowler spin can confuse inexperienced or poor batsmen.

Spin bowlers are generally given the task of bowling with old cricket balls that are outdated. A better new cricket ball suits a quick bowling technique rather than a spin bowling, while those who wear grip are better and reach a larger round. Spin bowlers are also more effective later on in the game, as the pitch dries up and begins to crack and collapse. This again provides more purchases for spinning balls and resulting in larger deviations. Spin bowlers that open bowling are rare, but are becoming a more viable option with the introduction of Twenty20 cricket when their favorable pitch conditions, and the ball is also generally more drifting in the air.

Equivalence

Both the finger spin and the wrist bowlers use different spin angles to confuse the batsman and fire him. Many of these variations have a direct equivalent in other disciplines, but the names used for different shipments may vary.

Terms

In recent years, spin bowling has become a skill of bowlers from the sub-continent of South Asia. The main reason for that is that pitches in the sub-continent provide more help to the spin bowling players. The faster the pitch slumps, the earlier the spinners come into the picture. Australian and South African pitches are usually very hard and bouncy, helping the bowlers fast. They did not break up much during the duration of the game. On the contrary, pitches in the sub-continent are not that difficult. They are not usually put together by the grass; therefore they break up faster and help the bowling players. In general, leg-spinis is regarded as one of the toughest types of bowling in which to maintain ball control, but is very effective in picking up wickets.

Flight, rotate, reflect, float, immerse

It is a habit among cricket commentators to describe and assess the quality of spin bowling in terms of flight characteristics, turning, bounce, floating , and dipping . All of this is the art of deceiving the batsman and takes a lot of practice. The basic bowling spin path is two-on-an-angle lines, but the above characteristics (described below) modify this 'normal' trajectory into a more complex form.

Turn: How many balls rotate after throwing (eg 5-degree deviation after meeting ground). It depends on the number and direction of the ball revolution. The movement and rotation of the ball vary, depending on the position of the wrist and fingers. A straight ball that is sometimes unpredictable can be useful inserted in the attack, but spin variation is the main technique used to deceive the batsman and pick up the wicket. The high turn rate is above 33 rev/sec, or 2000 rpm, which Graeme Swann consistently spins more than 2000 rpm, the most among British spinners to Liam Dawson also reaching 35 rounds/sec, or 2100 rpm. Also, the slower the balls, tend to deviate more. For offspinner, you have to bowl from wider off-stump to get the ball to turn into a right-handed batsman and force them to nick off the edge into the fielder or to the top off the stump.

Bounce: Get the ball to rise more than usual, so the ball meets the batsman at a greater than expected height. Sometimes, if the ball spins horizontally (eg a slider), the batsman will not be able to make contact with the ball and may hit the stump before the second club.

Drift: Make the ball move sideways while in the air. Slow shifts cause the batsman to cover the wrong line and the ball can catch the edge of the bat.

Dip: Receive the ball to the ground (fill the ground) at a shorter distance than usual. The final immersion causes the batsman to misjudge the ball's length.

Flights: throw a few more balls than usual, so time in the air before throwing longer. A slow ball with an extra flight can fool the batsman by thinking it's slower than that and therefore wrong in shooting him. This is very effective for offspinners. Usually spin bowlers rely on tricks during flight to produce lap, bounce, drift and dip, or a combination of them.
