Baseball's Batting Out Of Order
Batting out of Turn (or out of order) occurs when the official batting order is not followed in sequential order. When all nine batters have batted, the order is repeated from the top of the lineup.
According the Major League Base Official Rules 6.07 BATTING OUT OF TURN. (a) A batter shall be called out, on appeal, when he fails to bat in his proper turn, and another batter completes a time at bat in his place. (1) The proper batter may take his place in the batter's box at any time before the improper batter becomes a runner or is put out, and any balls and strikes shall be counted in the proper batter's time at bat.
Rule 6.07 (a) A batter shall be called out, on appeal, when he fails to bat in his proper turn, and another batter completes a time at bat in his place.
1.The official batting order is Joe, Bob, Mark & Tom
2.Joe gets up and grounds out to the shortstop (6-3)
3.Mark then bats out of turn (Bob should have been up).
4.Mark reaches first base safely on a single (1B) to center field (noted by the thin line drawn from home to center field)
5.Then Bob gets ready to hit.
6.But before a pitch is thrown the defense notices they are batting out of turn and inform the umpire.
1.Bob is ruled out because he should have been the batter prior to Mark. In this instance the catcher gets credited with the Putout (PO-2). I've added a "+" as a bookmark to reference a complete explanation at the bottom of the scorecard.
2.Since Mark already completed his at bat, resulting in a single, he remains on first base
3.The next batter after Bob is Mark, but Mark has already batted so Tom is the next batter.
The footnote for this play might say something like this:
+ Mark batted out of order before Bob. The defense discovered it after Mark singled but before any pitch to a subsequent batter. Bob was ruled out for batting out of order for the second out and Tom became the new batter.
