Penalty If the umpire is notified of such an infraction immediately after a batter completes their appearance, then the umpire considers that batter and the previous one. If the batter who just finished batting does not follow the previous batter in the written order, their plate appearance was improper, any advances or scores due to their action are nullified, they are removed from the bases, and the proper batter is called out. If batting out of turn is appealed, the entire play is nullified under Official Baseball Rule 6.03(b) and MiLB Umpire Manual 4.3. Any runners who advanced on the play would be returned to the base they occupied at the time of the pitch. However, an advance on a stolen base or wild pitch is not a result of the batter's illegal action, and would stand. If the improper batter hits into a double play in which they are put out along with another runner, the defense can still appeal an improper batter. If this is the case, the proper batter is declared out, the other runner called out on the double play is returned to the base they occupied at the time of the pitch, and the batter that follows the proper batter who was declared out will come to the plate. Under high school (NFHS) rules, any additional outs recorded on the play stand - the other out on the play would not be nullified, and the defense could still benefit from the double play. If the umpire is notified of such an infraction during a plate appearance (that is, a pitch has been thrown to the current batter, who has not yet been put out or become a runner), then the umpire considers the current batter and the previous one. If the current batter's name does not follow the previous actual batter's name in the written order, the current batter is improper. There is no penalty, but the situation is rectified — the proper batter comes to bat and assumes the improper batter's current count. In this situation, if the proper batter is on base, then they are skipped in the order, and the next batter in the order is now the proper batter. Example situations Suppose the batting order is: Abel, Baker, Charles, Daniel, Edward, Frank, George, Hooker, Irwin. Example: A proper batter fails to bat and is called out Abel bats and is put
