Philadelphia, PA – April 28, 2026 – The Philadelphia Phillies organization has parted ways with manager Rob Thomson, the team announced Tuesday. Bench coach Don Mattingly has been named interim manager for the remainder of the season. This move follows a disappointing 9-19 start to the 2026 campaign, leaving the club languishing in the standings. Thomson departs with a regular-season record of 355-270 during his tenure.
Thomson's dismissal marks a significant shift for a team that had reached the playoffs in each of his four seasons at the helm, including two division titles and a pennant appearance. Despite the recent struggles, a segment of opinion suggests the team's roster construction, particularly its defensive shortcomings, under President of Baseball Operations Dave Dombrowski, might bear equal scrutiny.
Third base coach Dusty Wathan has been elevated to bench coach. The timing of this managerial change places Philadelphia in the midst of a league-wide trend, with the Boston Red Sox having recently dismissed Alex Cora.

Roster Woes and Managerial Shifts
The Phillies' current performance, marked by an abysmal stretch that saw them lose 11 of their last 12 games, has fueled widespread fan dissatisfaction and internal discussions about personnel changes. Even after snapping a 10-game losing streak, the team has struggled to gain consistent footing. Concerns have been raised about the team's offensive output against left-handed pitchers, with right-handed hitters posting a .505 OPS in such situations.
Speculation regarding Thomson's future had been building for days, with some analyses even placing him among the more likely managers to be fired in Major League Baseball. Thomson himself had indicated that, amidst the team's struggles, thoughts of his dismissal were not at the forefront of his concerns.
A Pattern of Change
This decision represents the second instance of Dombrowski parting ways with a manager during his tenure in Philadelphia. The team's current slump is particularly jarring given the high expectations that preceded the season. The Phillies are noted to have had the third-best record in baseball since Thomson initially took over the managerial position, a detail that adds a layer of complexity to the recent upheaval.

Don Mattingly, whose son Preston Mattingly serves as the team's general manager under Dombrowski, now steps into the interim role. This arrangement is reportedly intended to last through the season's end.
Background
Rob Thomson assumed the managerial duties in Philadelphia after previously serving as bench coach. His initial tenure saw a period of consistent postseason appearances, a stark contrast to the team's current standing. The broader context of the Phillies' performance includes notable losses to division rivals like the Atlanta Braves, contributing to the pressure for change.
