5/13/2026, 1:08:15 PM
Background & Context
The Boston Red Sox and Philadelphia Phillies opened a three-game series at Fenway Park on May 12 after each dismissed its season-opening manager. Boston terminated Alex Cora on April 25 and released his staff the same day. Two days later, the Phillies fired Rob Thomson. Interim managers Chad Tracy (Red Sox) and Don Mattingly (Phillies) assumed control, creating the first matchup since 2002 in which two clubs with interim managers meet within their first 45 games of a season.

- Starting Pitchers: Boston’s opener Jovani Morán (followed by Brayan Bello); Philadelphia’s ace Zack Wheeler
- Notable Players: Boston’s Jarren Duran, Willson Contreras, Trevor Story; Philadelphia’s Bryce Harper, Kyle Schwarber, Trea Turner
Data & Statistics
- Records Under Interims: Red Sox 7-6 (versus 10-17 under Cora); Phillies 10-3 (versus 9-19 under Thomson)

- Pitching Matchups: Wheeler 2-1 with a 2.81 ERA against Boston; Bello tossed seven innings, allowing one run in a recent win over Detroit
Why It Matters / Impact
The series is historically notable: the Elias Sports Bureau confirms it is the first such convergence in 24 years. Both clubs view the games as a litmus test for their interim leadership and a potential catalyst for postseason positioning. Strong performances could cement Tracy’s and Mattingly’s roles; poor results may prompt further front-office moves.
Official Statements & Responses
Phillies interim manager Don Mattingly said the club is “moving in the right direction,” citing improvements in pitching, defense, and offense. Red Sox interim manager Chad Tracy stressed the need to convert more scoring chances, noting that “nothing can go wrong” when the team capitalizes. MLB.com analyst Thomas Harrigan highlighted the rarity of two interim-managed teams facing each other so early in a season. Both clubs reported better win-loss records since the managerial changes.
Criticism & Opposition
Analysts continue to question Boston’s offensive strategy. The team’s low power output—29 homers in 40 games—and reliance on stolen bases have drawn criticism, with commentators noting that “they can’t slug their way to second base, so they’re running their way there.” Persistent struggles to drive in runners with runners in scoring position have limited the Red Sox’s ability to win close games.
