If a player has a 3-2 count and the plate umpire calls a ball, but the base umpire then reverses it to a strike, what happens to the batter/runner when they overrun first base?

In this scenario, when a player has a 3-2 count and the plate umpire initially calls a ball but the base umpire then changes the call to a strike, it is important to understand the implications for the batter when they overrun first base. When a batter receives a strike call in this situation, they become a runner once they are put out by the strikeout. However, since the call is changed during the at-bat, the status of the batter is crucial.

If a player overrun first base after being called out on a third strike that is later deemed to be a ball but is reversed to a strike by another umpire, the player is considered to be in a new situation, with the bases clear. In this particular context, since the revised strike is solidified, if they overrun first base and do not attempt to advance toward second or are not tagged while off the base, they are considered safe at first base in this instance under specific rule interpretations.

This understanding aligns with the nature of how plays involving overruns are handled, meaning that if the overrun does not lead to any interference or attempt to advance, the player retains their safe status at first base. This illustrates how the rules of baseball support
