The field for the upcoming 2025 Home Run Derby underwent a late-hour change Saturday, as Matt Olson of the host Atlanta Braves was announced as a replacement for teammate Ronald Acuña Jr., who will no longer participate.

Ronald Acuña Jr. won’t participate in the Home Run Derby, replaced by Atlanta teammate and fellow All-Star Matt Olson.

Olson hit in the 2021 derby while a member of the then Oakland Athletics.Acuña was expected to make his third appearance.Olson is not as popular a player as Acuña, so it's definitely disappointing for the home crowd that Acuña will not be in the event.
