Carl Prean’s constant twiddling of his
bat (racket) is to deceive opponents trying to read the different spin. One of the most
difficult players in the world to play against, constantly turning the
bat round in his hand, a technique referred to as twiddling. The two
surfaces, different material, vary the spin on the ball. The long pimples,
there – very good for hitting through the ball, giving no spin, very flat, very
awkward. The reverse side, the red side there – very good for imparting spin.
