Baseball is a
bat-and-ball sport played between two teams of nine players each. The aim is to score
runs by hitting a thrown
ball with a
bat and touching a series of four
bases arranged at the corners of a ninety-foot
diamond. Players on the
batting team take turns hitting against the
pitcher of the
fielding team, which tries to stop them from scoring 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 via 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 each team constitutes an
inning and nine innings make up a professional game. The team with the most runs at the end of the game wins.
