Cricket works the following: While one team is on the field, 2 players from the opposite team are on the pitch. These two are called batsmen. One of the batsmen is the striker while the other batsman is on the opposite end of the striker. The striker is the one who hits the ball, tries to defend the wicket.
A player from the fielding team, called bowler, will throw the ball at the striker. This action is called bowling. It is important that the bowler throws the ball over his shoulder; otherwise he will be called out. The bowler throws the ball so that it will hit the ground in front of the wicket and will jump of the ground.
While one fielder is bowler, another fielder is wicket-keeper. The wicket-keeper stands behind the striker and tries to catch the balls the striker is missing. The wicket-keeper wears webbed gloves, to protect his hands and help him catch the ball.
The wicket-keeper and bowler are elected by the team captain. The team captain is responsible for the strategies of the game. He tells every player his/her position. However, a bowler can only bowl a certain amount of balls/overs per inning. Therefore the position of the bowler changes during the inning. However, the batsman remains until the fielding team managed to get him out.
During the game, the batsmen try to score as many runs as possible. A run is scored when both batsmen arrive at their opposite wicket. The fielding team is responsible for bowling the ball against the striker and to get the batsmen out. There are several ways of getting them out. They are explained later on. If the fielding team managed to get a batsman out, a new batsman will come to replace him. This goes on, until the fielding team managed to get 10 batsmen out. Notice there will be batsman left, as there are always 11 players. However he/she will not have a partner and therefore the fielding team will get the position of the batting team and the batting team will become the fielding team.
