The Phillies fired Rob Thomson after a 9-19 start and handed the dugout to Don Mattingly, a blunt reset for a club that has spent the first weeks of the season looking nothing like a contender. The change came this week, after a stretch that left the Phillies with more questions than answers and pushed Trea Turner and the rest of the lineup into a new era under an interim manager.
For now, the expectation is simple: the Phillies should play better for Mattingly than they did for Thomson, if only because they cannot play worse. That is not a projection built on optimism. It is a verdict on how far the team had fallen, even as the roster still carried the burden of a club that won 95 and 96 games over the past two seasons and reached the playoffs for four consecutive years.
John Middleton approved the move, and Dave Dombrowski now has to explain why this roster needed a jolt before it began to collapse beyond repair. He had the same justification last offseason if he wanted to shake up the team then, when the front office kept the group mostly intact instead of making the kind of broad changes that might have addressed obvious flaws. Instead, the Phillies entered this season with a lineup built around four regulars who were 33 or older, a point Jayson Stark flagged in March when he noted the club was trying to become only the third team to win a World Series with that kind of age profile.
The biggest hole was visible before the firing and has only grown more obvious since. The Phillies tried to sign Bo Bichette with a seven-year, $200 million offer, then watched the Mets land him on a three-year, $126 million deal. Without that right-handed bat, the roster has been described internally as seriously flawed, and the club’s only significant right-handed hitting addition was right fielder Adolis García. Felix Reyes, a rookie right-handed hitter, batting cleanup last Tuesday was a symptom of how thin the lineup has become.
The numbers against left-handed pitching make the case even sharper. The Phillies were 0-10 in games started by left-handers, not counting openers, and entered Tuesday with a.179/.270/.293 slash line against lefties. Those marks were the worst in the majors in each category at that point, a staggering collapse for a team that had already played 13 straight games against the Chicago Cubs and Atlanta Braves and still could not find a workable offensive rhythm.
That is why the managerial change is only part of the story. Dombrowski is expected to try to hire Alex Cora again once the season is over, a familiar name for a front office that sees him as a mentor. Cora passed on jumping back into managing just days after getting fired by the Boston Red Sox, but the Phillies have long history with him: Dombrowski and Cora led Boston to the 2018 World Series title. If the season is already a rescue project, Cora looks like the target for the next one.
For the moment, Mattingly gets the job of stabilizing a team that has lost its edge and its credibility in the same stretch. The Phillies are supposed to look better under him. The real measure will be whether the new voice does more than mask a roster that, at 2026’s early edge, has not been Dombrowski’s finest work so far.
