In baseball, an out (also informally "away" or "down" when mentioning the number of batters currently out) occurs when the defensive, or fielding, team effects any of a number of different events, and the umpire rules a batter or baserunner out. When a player is called out, he is said to be retired. When three outs are recorded in an inning during a team's turn at offense, that team's half of the inning finishes, and it is said that "the side is retired."
