In
baseball,
batting out of turn or
batting out of order refers to an event in which a
batter makes a
plate appearance out of sequence from the
batting order specified in the lineup card submitted by the
manager to the home plate
umpire before the start of the game. The initial batting order is a list of the nine
position players selected by the manager to play that game, indicating the sequence in which they will bat and the position to which they have been assigned for the game. During the game, batters make a plate appearance in the order specified by the batting order, repeating the sequence once the ninth batter has made a plate appearance.
