Former Major League Baseball player Michael Morse experienced a rare sequence of events involving an overturned grand slam [1, 2].
The incident highlights the complexities of umpire reviews and the unusual physical requirements that can result from correcting a play in real time. Because the ruling changed after the initial action, the game's flow was interrupted to satisfy the technical requirements of the corrected call.
According to reports, the play was initially ruled in play [1, 2]. However, an umpire review subsequently corrected the original call, overturning the play to a grand slam [1, 2]. This reversal created a unique situation for Morse, who had already participated in the initial sequence of the play.
To properly record the grand slam following the review, Morse was required to repeat the action. This forced him to swing without a bat, and run the bases again [1, 2]. The requirement ensured that the official record reflected the corrected ruling of the home run.
Such occurrences are uncommon in professional baseball, where review processes typically result in a simple change of the scoreboard or a player being returned to a base. The necessity for a player to mimic a swing without equipment serves as a physical manifestation of a rulebook correction. Morse's experience remains a notable example of the intersection between modern replay technology and traditional baseball rules [1, 2].

This incident illustrates the tension between the desire for absolute accuracy via replay and the theatrical nature of baseball. While the review ensured the correct statistical outcome, the requirement for a player to reenact a play without a bat demonstrates how rigid rule interpretations can lead to surreal moments on the field.
