People from most other countries think it is very, very slow, but the English think it is exciting. There are two teams with eleven players on each team in a cricket match. They play outdoors on a field. They play around two wickets. A wicket is three sticks in the ground with two sticks across them at the top. The wickets are twenty meters apart. One player is a bowler. He stands by one wicket and throws a ball at the other wicket. He tries to hit one of the top sticks and make it fall to the ground. Another player is a batsman. He holds a stick called a bat. He stands behind the second wicket. He tries to hit the ball before it hits the sticks. If he hits the ball, he runs to the other wicket. Sometimes he can run from one wicket to the other several times until a player in the field catches the ball and throws it back to the wickets. An important match can continue for 4 or 5 days. The players make hundreds of runs. Cricket began in England in the 1300s. It became a major sport in the 1700s. Englishmen taught the game to people in their colonies.
