Philadelphia Phillies Fire Manager Rob Thomson After 4 Years

Action has been taken. The Philadelphia Phillies have fired manager Rob Thomson in the wake of the team’s 9-19 start, the team announced on Tuesday morning. Bench coach Don Mattingly, who was previously the manager of the Los Angeles Dodgers and Miami Marlins, will be Philadelphia’s interim manager, while third base coach Dusty Wathan is now the team’s bench coach. The Phillies recently lost 10 consecutive games, have lost 10 of their last 12 and their 9-19 mark is tied with the New York Mets for the worst record in MLB (32.1% winning percentage). Philadelphia’s starting rotation has the worst ERA (5.80), WHIP (1.64) and opponent batting average (.307) in the sport. Meanwhile, its offense is 29th in batting average (.219) and on-base percentage (.294), 28th in runs (102) and hits (208) and 27th in slugging percentage (.362). Thomson was Philadelphia’s bench coach from 2018-22 and promoted to interim manager when Joe Girardi was fired in June 2022. The Phillies then proceeded to reach the 2022 World Series and kept Thomson on a long-term deal. Philadelphia made the playoffs in each of the following three seasons (2023-25), with the Phillies posting a combined 355-270 record in the regular season and 21-17 in the postseason under Thomson from 2022-26. They won the NL East in 2024 and 2025.​The Philadelphia Phillies have fired manager Rob Thomson in the wake of the team’s 9-19 start to the 2026 MLB season.
