Baseball is a team game played by two teams of nine players each on an enclosed Baseball field under the direction of a manager in accordance with rules under jurisdiction of one or more umpires.

An offending player tries to hit the ball away from the reach of the defenders and score runs by running around the bases. Players of the defending team try to out the player who is batting. Both the teams take turns at batting and fielding. Three consecutive outs from each team make an innings, and nine innings make a game. The objective of each team is to win by scoring more runs and try to prevent opponents from scoring runs.

The baseball field, also called the baseball diamond, is a specially-designed field composed of two basic parts − the infield and the outfield.

The infield:

In baseball the physical infield is where most of the action in a baseball game occurs, as it includes that area where the all-important duel between the pitcher and batter takes place. ... Together, home plate and the three bases form a diamond around the pitcher, with each side of the diamond measuring 90 feet. The infield depth at which you can play certain hitters depends on the inning, the score, how fast a runner is, and where runners are on the bases.

The outfield:

The outfield is covered by three players, the center fielder, right fielder, and left fielder. These players are responsible for catching fly balls, running down hits to the outfield, and getting the ball back to the infield as quickly as possible.

Baseball, usually considered the national sport or pastime of the United States, originated in the country and quickly spread to Netherlands, Italy, Belgium, England, Spain, Australia, Tunisia, and other parts of the world.Baseball was popularized heavily.
