On April 28, 2026, Don Mattingly was appointed as the interim manager of the Philadelphia Phillies after Rob Thomson was dismissed from his position following a challenging start to the season. The Phillies began their campaign with a disheartening record of 9-19, prompting the front office to make a change in leadership.
The decision to hire Mattingly comes as a surprise given his previous statements regarding his reluctance to manage again due to the time-consuming nature of the role. In December 2025, Mattingly had remarked that he had no interest in returning to management, yet circumstances have led him back into the dugout.
The timeline of events leading up to Mattingly’s appointment reveals significant shifts within the organization:
- Rob Thomson was hired as manager on June 3, 2022.
- The Phillies started the 2026 season poorly, with a record of 9 wins and 19 losses.
- Thomson was fired on April 28, 2026, after this disappointing start.
- Mattingly was named interim manager on the same day.
Mattingly brings with him managerial experience from his tenures with both the Los Angeles Dodgers (2011-2015) and Miami Marlins (2016-2022). His overall career record stands at 889-950, along with a postseason record of 10-14.
Interestingly, Mattingly’s son, Preston Mattingly, currently serves as the general manager for the Phillies, adding another layer of familial connection to this transition. This managerial change marks the fourth time in thirteen years that the Phillies have opted for a midseason managerial change—an indication of ongoing struggles within the franchise.
The implications of this shift are significant for both Mattingly and the team. As he steps into this role, he becomes the 58th manager in Phillies history, tasked with revitalizing a struggling squad. His ability to navigate these challenges will be closely scrutinized by fans and analysts alike.
