Braves reliever Joe Jiménez is expected to miss much of the 2025 season and possibly all of it after surgery to repair cartilage in his left knee.

The team confirmed Monday night that Jiménez is likely to be sidelined for approximately eight to 12 months following the operation last week.

Jiménez was expected to open next season as one of Atlanta’s top setup men. The 29-year-old right-hander posted a 2.62 ERA with three saves in 2024. He established career highs by pitching 68 2/3 innings in 69 games.

The surgery came about a year after the Braves re-signed Jiménez to a $26 million, three-year contract on Nov. 2, 2023. Jiménez, who began his major league career by pitching six seasons for the Detroit Tigers, has been one of Atlanta’s best relievers the last two seasons.

The Braves acquired Jiménez from Detroit in a trade before the 2023 season, sending two minor leaguers to the Tigers. He was an All-Star with Detroit in 2018.
