4/28/2026, 11:41:49 PM
The Firing and Interim Appointment
On April 28, 2026 the Philadelphia Phillies terminated manager Rob Thomson after the team fell to a 9-19 record, tying the New York Mets for the worst mark in Major League Baseball. Bench coach Don Mattingly was named interim manager for the remainder of the season. Third-base coach Dusty Wathan was promoted to bench coach, and Triple-A manager Anthony Contreras assumed third-base duties.
Recent History of the Franchise
Thomson assumed interim managerial duties on June 3, 2022 after the club dismissed Joe Girardi. He guided the Phillies to a 65-46 finish, a National League pennant, and a World Series appearance that year. The team posted 90-72 (2023), 95-67 (2024) and 96-66 (2025) seasons, winning the NL East in 2024 and 2025. In December 2025 Thomson signed a contract extension through the 2027 season.

Implications for the Club
The Phillies entered 2026 as preseason NL East favorites and hosts of the All-Star Game, yet the early collapse threatens their playoff outlook and raises questions about roster construction, aging contracts, and front-office strategy. The interim appointment creates the first MLB father-son manager/GM pairing, a historic novelty that may influence future hiring decisions.
Official Statements
President Dave Dombrowski said Thomson “has been a good manager for us since 2022” and that the organization “always looks at everything that’s taking place.” The club’s release announced that “Don Mattingly will serve as interim manager through the end of the 2026 season.”
Criticism and Opposition
Analysts highlighted the roster’s rapid aging, under-performance of key hitters (Harper, Schwarber, Turner) and starters (Nola, Luzardo, Painter), and the lack of offseason moves to address payroll-heavy underachievement. Alex Cora’s decision to decline the managerial offer was cited as evidence that the club’s challenges extend beyond the bench.

- ERA is reported as 5.13 by some outlets and 5.80 by others.
- Payroll figures range from $284 M to $315 M.
- Run-differential numbers differ between –54 and other unspecified values.
