 There are a number of named basic fielding positions, some of which are employed very commonly and others that are used less often.However, these positions are neither fixed nor precisely defined, and fielders can be placed in positions that differ from the basic positions.The nomenclature of the positions is somewhat esoteric, but roughly follows a system of polar coordinates – one word (leg, cover, mid-wicket) specifies the angle from the batsman, and is sometimes preceded by an adjective describing the distance from the batsman (silly, short, deep or long).
