The carrom ball is a style of spin bowling delivery used in cricket, where the ball is held between the thumb and a bent middle finger in order to impart spin. The grip is unusual and the ball can spin to either the off or leg sides or travel straight, depending on the degree of grip. The carrom ball can cause serious confusion for the batter when the bowler gets it right, as it is difficult to pick. The carrom ball was first used by the Australian Jack Iverson from Victoria, who used it throughout his Test cricket career in the period after the Second World War, although he did not use the name "carrom ball". The method was almost forgotten by the end of the 1970s, but it was revived by Sri Lanka’s Ajantha Mendis and India’s Ravichandran Ashwin in the modern days of spin bowling. Sri Lankan Rangana Herath is believed to be the first left-handed spin bowler to have used the method in international cricket, dismissing Australian opener David Warner with a delivery in the carrom ball style during a test match.
