There are two teams who take turns batting and fielding on the ground. Each of them has nine players and works(第三人称单数) together to create exciting games to the audience.

Firstly ,one team is at bat and the other one is in the field. Eachteam constitutes aninining, and a game consists of nine innings. The batting team attempts to score runs by hitting a ball that is thrown by the pitcher with a bat swung by the batter, then running counter-clockwise around a series of four bases: first, second, third, and home plate. A run is scored when a player advances around the bases and returns to home plate. Then an opposing batter of the home team attempts to hit the pitches and safely reach base, and the fielders attempt to put the batter out through various plays. A batter who misses three pitches, or fails to swing at three judged hittable, is out on "strikes"; but if the pitcher first throws four pitches out of the strike zone, the batter obtains a base on balls, or "walks" to first base. When the fielding team puts out three batters, the teams exchange places. If the score is tied at the end of nine innings, play continues into extra innings until one team has scored more runs than the other in an equal number of turns at bat.

As audience, we usually take a closer look at the special players. These people are employed with a skillful contact hitter: the runner takes off with the pitch drawing the shortstop or second baseman over to second base, creating a gap in the infield for the batter to poke the ball through.

 In baseball games, the umpire is the person charged with officiating the game. This umpire calls balls and strikes, calls fair balls, foul balls short of first/third base, and makes most calls concerning the batter or concerning baserunners near home plate.
