The game is played in "innings". Professional baseball games have 9 innings. In an inning, each team has one turn to bat and try to score "runs", adding one point. When one team hits the ball, the other team defends and tries to get three players on the other team "out". The team that is playing defense always has the ball. This is different from other team sports. When the team on defense gets three players out, it is their turn to try and score runs. Then the team that was batting starts playing defense, and the team that was playing defense starts batting. After nine innings, the team that has the most runs is the winner. If the teams have the same number of runs, they play more innings until one team wins. At the start of the game, the home team pitches, while players on the visiting team bat. Only one player can bat at a time.
