The Athletic’s Matt Gelb reports that the Phillies have fired manager Rob Thomson.
Don Mattingly, who joined the team as bench coach this offseason, will take over as interim manager. Thomson becomes the second manager fired this month after the Red Sox fired Alex Cora over the weekend. In fact, many reports suggest that Thomson’s firing could be directly tied to that, since Dave Dombrowski, the Phillies’ president of baseball operations for the Phillies, has a close relationship with Cora from their time together in Boston. A potential manager swap was made easier with the Phillies’ getting out to a 9-19 start to the season, tied with the Mets for the worst record in baseball. Thomson ends his Phillies career with a record of 355-270 for a .568 winning percentage, which is second-best in franchise history. He took the Phillies to the World Series in 2022, but the team then lost in the NLCS in 2023, the Division Series in 2024, and the Division Series in 2025. Thomson will likely get another chance to manage if he wants one.
