The term 'struck out, in baseball' can be summarized as a situation in which a batter is unable to hit the ball and is thus called out. This is also referred to as 'fanned' (6 letters). In baseball, a strikeout occurs when a pitcher throws three strikes to a batter before the batter puts the ball in play. A strikeout is recorded as an out for the defensive team and a failure for the offensive team.
