Baseball is a game played by two teams of nine which compete to earn “runs” by hitting the ball and running a circle from the home base through the first, second, third base and back to the home base.

The territory of it is within a fan-shaped area of 90 degrees. The square area is called the “diamond” and also the infield. The area between the diamond and the outer fence is the outfield. The offense team appoints one batter each time. If the batter hit a legal ball, he or she will be a runner to the first base. And runners can proceed to the next bases if other batters hit a legal ball. The defence team deploys 1 player as the pitcher, 1 as the catcher, 4 in the infield, and 3 in the outfield.

An inning is two teams take turns to bat and earn runs. A game has nine innings but more of them if there is a tie.
