What is a flipper?

A flipper is a relatively slow ball that acts more or less like a top-spinner. It is produced by gripping the ball mainly with the tips of the first and third fingers, and squeezing, of ‘flipping’ it out, so that it emerges from the back of the hand with some amount of top spin on it. If this has been effectively performed, it will hurry through without deviation, gaining pace as it pitches and keeping low.
