Weiss spent the previous eight years as the Braves' bench coach after spending four years (2013-2016) as the manager of the Colorado Rockies, where he finished with a record of 283-365.
The Atlanta Braves finished the year with a 76-86 record under the final year of Brian Snitker as manager, who personally decided to step down after the 2025 season ended.
Under Snitker, the Braves went 811-668, including a World Series in 2021. This past season was the Braves' first losing record under Snitker since his second season in 2017, when the team went 72-90.
From 2018 to 2024, Snitker led the Braves to seven straight postseason appearances and six straight National League East division pennants.
He ends his tenure with a Manager of the Year Award and the third-most winningest manager in Braves history.
