Philly Fires Thomson, Taps Mattingly as Interim After 9-19 Start

Phillies president of baseball operations Dave Dombrowski delivered the news to Thomson early Tuesday morning at Citizens Bank Park, relieving him of duties after a 10-game losing streak capped the team's brutal opening to 2026. The move came one day after Cora, freshly dismissed by the Boston Red Sox, turned down Philadelphia's offer on Monday. Dombrowski then elevated Mattingly, whose son Preston serves as the Phillies' general manager, reconfiguring the coaching staff in a Monday off-day meeting.[1][3][4][5] Thomson's tenure boasted a 355-270 record (.568 winning percentage), including four consecutive playoff runs and a World Series appearance in 2022, but the 9-19 mark—Philadelphia's worst start since 2003—proved too much for the front office. Owner John Middleton stayed out of the decision, which Dombrowski called final. The Phillies now chase an NL wild-card spot from their South Broad Street home.[1][2][4][5] Thomson expressed no animosity, stating he understands the firing and would welcome staying with the organization. Star slugger Bryce Harper shared his reaction, underscoring the clubhouse shock. Mattingly, a Yankees legend and bench coach, inherits a talented roster needing revival in the competitive NL East.[1][7][9] Fans in Philly's sports bars and tailgates outside Citizens Bank Park buzz with debate: Can Mattingly steady the ship for a playoff push, or signal deeper issues under Dombrowski? The interim skipper's first test looms soon, with Pennsylvania baseball faithful hoping for a turnaround.[2][6]
