There are two batsman up at a time, and the batsman being bowled to (the striker) tries to hit the ball away from the wicket. A hit may be defensive or offensive. A defensive hit may protect the wicket but leave the batsmen no time to run to the opposite wicket. In that case the batsmen need not run, and play will resume with another bowl. If the batsman can make an offensive hit, he and the second batsman (the nonstriker) at the other wicket change places. Each time both batsmen can reach the opposite wicket, one run is scored. Providing they have enough time without being caught out and dismissed, the batsmen may continue to cross back and forth between the wickets, earning an additional run for each time both reach the opposite side. There is an outside boundary around the cricket field. A ball hit to or beyond the boundary scores four points if it hits the ground and then reaches the boundary, six points if it reaches the boundary from the air (a fly ball). The team with the highest number of runs wins a match.
