(known as a "single") can be scored after the bowler, who is in one batsman's ground, has thrown the ball to the batsman in the other ground. That batsman (known as the "striker") can hit the ball away from the fielders. Both the striker and the non-striker then run the length of the pitch, while running to the other ground. They will cross each other. To complete a run, both batsmen must "make their ground", meaning some part of their person or held bat touches the ground behind the crease (line) at the other end of the pitch. If the wicket in either ground is knocked off by a fielder with the ball when no batsman is in that ground, then the ball becomes dead and one of the batsmen (usually the one nearest to that ground) is run out of the game for the rest of the innings.
