Fielding in the sport of cricket is what fielders do to collect the ball when it is struck by the batsman, in such a way as to either limit the number of runs that the batsman scores or get the batsman out by catching the ball in flight or running the batsman out. A fielder may field the ball with any part of his person. However, if while the ball is in play he wilfully fields it otherwise (e.g. by using his hat), the ball becomes dead and 5 penalty runs are awarded to the batting side unless the ball previously struck a batsman not attempting to hit or avoid the ball.
