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



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). However, in 2010 Shahid Afridi of Pakistan bowled the fastest spin delivery of 134  km/h in a T20 match against New Zealand


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

  • Off break – Right-handed with finger spin technique. (e.g. Muttiah Muralitharan, Saqlain Mushtaq)
  • Left-arm orthodox spin – Left-handed with finger spin technique. (e.g. Daniel Vettori, Shakib Al Hasan)
  • Leg break – Right-handed with wrist spin technique. (e.g. Shane Warne)
  • Left-arm unorthodox spin – Left-handed with wrist spin technique. (e.g. Brad Hogg)
  • 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.

    This variety of trajectories achievable by a spin bowler can bewilder inexperienced or poor batsmen.

    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.


    Both finger spin and wrist spin bowlers use a range of different angles of spin to confuse the batsman and dismiss him. Many of these variations have direct equivalents in the other discipline, but the names used for the various deliveries may be different.


    In recent times, spin bowling has been a forte of the bowlers from the South Asian sub-continent. The primary reason for that is that the pitches in the sub-continent provide more help to the spin bowlers. The faster the pitch degenerates, the earlier the spinners come into the picture. Australian and South African pitches are usually very hard and bouncy, helping the fast bowlers more. They do not break up very much during the duration of the match. In contrast, pitches in the sub-continent are not that hard. They are not usually held together by the grass as much; hence they break up more quickly and help spin bowlers. In general, leg-spinis considered to be one of the toughest types of bowling in which to keep control of the ball, but it is very effective in picking off wickets.

    Flight, turn, bounce, drift, dip

    It is customary among cricket commentators to describe and judge the quality of spin bowling in terms of the characteristics flight, turn, bounce, drift, and dip. All these are arts to deceive the batsman and require lots of practice. The basic trajectory of spin bowling is two-lines-at-an-angle, but the above characteristics (described below) modify this 'normal' trajectory into more complex shapes.

    Turn: How much the ball turns after pitching (e.g. 5 degree deviation after meeting the ground). It depends on the number and direction of revolutions of the ball. The movement and rotation of the ball varies, depending on the position of the wrist and the finger. An occasional unexpected straight ball can usefully be included in an attack, but spin variation is the main technique used to deceive the batsman and take wickets.

    Bounce: Getting the ball to bounce more than normal, so that the ball meets the batsman at a greater height than expected. Sometimes, if the ball spins horizontally (e.g. a slider), the batsman will not be able to make contact with the ball and it may hit the stumps before the second bounce.

    Drift: Getting the ball to move sideways while in air. Late drift causes the batsman to cover the wrong line and the ball may catch the edge of the bat.

    Dip: Getting the ball to pitch (meet the ground) at a shorter distance than normal. Late dip causes the batsman to misjudge the length of the ball.

    Flight: throwing the ball up a bit more than normal, so that its time in the air before pitching is longer. A slow ball with extra flight may deceive the batsman into thinking it is slower than it is and therefore mistiming his shot. This is very effective for offspinners. Usually a spin bowler relies on tricks during flight to produce turn, bounce, drift and dip, or combinations of them.
