In cricket, to score a run, a striker must hit the ball and run to the opposite end of the pitch, while his non-striking partner runs to his end. Both runners must touch the ground behind the popping crease with either his bat or his body to register a run. If the striker hits the ball well enough, the batsmen may double back to score two or more runs. At times, four or more runs may be scored off a single ball in this fashion. This is known as running between wickets. However, if a fielder knocks the bails off the stumps with the ball while no batsman is grounded behind the nearest popping crease; the nearest batsman is run-out. (See: Dismissal of a Batsman for more details.) The batsmen will elect to run only when they believe they have a good chance of scoring runs without getting out in this fashion. If the striker hits the ball to a nearby fielder, the batsmen may simply choose not to run.
