Baseball is a bat-and-ball sport in which two rival sides of nine players alternate batting and fielding duties. The game begins when a pitcher from the fielding side throws a ball that a batter from the batting team attempts to hit with a bat. The offensive team's (batting squad) goal is to hit the ball into the field of play, allowing its players to advance counter-clockwise around four bases and score "runs." The defense group's (fielding player's) goal is to keep hitters from turning runners and runners from advancing all around bases.
When a runner legitimately moves all around bases in sequence and hits the home plate, a run is recorded (the place where the player started as a batter). The winning side is the one that scores its most runs by the conclusion of the match. The batting squad's first goal is to have a player safely touch first base.
If a batter gets first base before being ruled "out," he or she might try to move to the next base as a runner, either immediately or during teammates' turns at-bat. The fielders seek to avoid scores by getting hitters or runners "out," or removing them from the game.
Pitchers and fielders have different techniques for getting batters out.
The batting and fielding teams exchange turns, with the hitting team's turn finishing once the teams have recorded three outs.
Each side gets one inning of batting session. A match usually lasts nine innings, with the victorious side being the one who scores the most runs in the end. Extra innings are frequently performed if the score is tied after nine innings. Baseball does not have a game clock, despite the fact that most games terminate in the ninth inning.
