Baseball is a bat-and-ball game played between two teams of nine players who take turns batting and fielding.
The offense attempts to score more runs than its opponents by hitting a ball thrown by the pitcher with a bat and moving counter-clockwise around a series of four bases: first, second, third and home plate. A run is scored when the runner advances around the bases and returns to home plate.
Players on the batting team take turns hitting against the pitcher of the fielding team, which tries to prevent runs by getting hitters out in any of several ways. A player on the batting team can stop at any of the bases and later advance on a teammate's hit or other means. The teams switch between batting and fielding whenever the fielding team records three outs. One turn at bat for both teams, beginning with the visiting team, constitutes an inning, and nine innings a game. The team with the most runs at the end of the game wins.
Evolving from older bat-and-ball games, an early form of baseball was being played in England by the mid-18th century. This game was brought by immigrants to North America, where the modern version developed. By the late 19th century, baseball was widely recognized as the national sport of the United States. Baseball is now popular in North America and parts of Central and South America and the Caribbean, East Asia and Europe.
