Tag out
In baseball and softball, a tag out, sometimes just called a tag, is a play in which a baserunner is out because a fielder touches him with the ball or with the hand or glove holding the ball, while the ball is live and the runner is in jeopardy of being put out (usually when he is not touching a base). A baserunner is in jeopardy when any of the following is true: He is not touching a base (excluding overrunning of first base or when advancing to an awarded base, such as on a base on balls).
