Atlanta Braves star Ronald Acuña Jr. was the first to commit to the event, to be held at his home yard, Truist Park in Atlanta. However, one day after the field was finalized, MLB announced that his teammate Matt Olson would replace him.

Matt Olson is set to replace his Atlanta Braves teammate, Ronald Acuña Jr., in the 2025 MLB All-Star Home Run Derby.

It's a new era for MLB's Home Run Derby in 2025. As baseball's most iconic exhibition prepares to take over Truist Park in Atlanta next week, the field will not feature any players who participated last year.

The most-awaited event of MLB's All-Star Week, the Home Run Derby will take place at Truist Field, home of the Atlanta Braves, in 2025.

Ronald Acuña Jr. will be looking to become the first Brave to win the Home Run Derby, and he'll be doing it at home in Atlanta, too.

Acuña helped lead the Braves to a 9-2 win against the Athletics — just their third victory in 13 games — a day after an embarrassing 10-1 series-opening loss. The Braves hit a season-high five homers, with others from Drake Baldwin, Austin Riley and Marcell Ozuna, who hit his first in 22 games, since June 13.

Atlanta's own Ronald Acuña Jr. will represent the Braves and look to take home the chain in front of a home crowd. Though Acuña didn't make his season debut until late May, he's been on fire since returning to the field and is now up to 11 home runs, 20 RBI and a .336 batting average in 41 games.

The Athletics' Brent Rooker will be one of eight batters looking to win the home run derby ahead of Tuesday night's MLB All-Star Game in Atlanta.

Athletics slugger Brent Rooker became the latest entrant in the forthcoming Home Run Derby on Thursday. Just one spot remains vacant in the eight-player field. Rooker, 30, has hit .270/.346/.489 (130 OPS+) with 19 home runs in his first 94 games this season.
