3. What are the main aims of Fielder?

There are twofold aims of a fielder. One is to stop or minimize the runs of the opponent batsmen. This is best done by collecting the ball after it has been hit by the batsman  and returning it  to the wicket keeper as fast as doable, to stop scoring runs. The other aim is to retire  or dismiss the batsman either by catching the ball before it touches the ground or throwing the ball to fall the bail bonds on the top of the stumps. The successful execution of either of two wouldn’t allow the batsman to score run.
