Complete Red Sox trade deadline grades following massive top prospect purge

Key Points:

• Boston Red Sox chief baseball officer Craig Breslow made several significant trades at the 2026 deadline, aiming to address team needs ahead of a playoff run, earning an overall grade of B for his efforts.
• The trade for Curtis Mead was disappointing due to a fractured wrist injury shortly after joining the team, though Mead's solid performance prior to injury offers hope for a positive impact upon return (Grade: B).
• The acquisition of catcher Adley Rutschman and Jake Rogers cost Boston three top-five prospects but added offensive improvement and depth, with some risk due to Rutschman's recent offensive struggles and a potentially shortened 2027 season (Grade: B-).
• A smaller trade brought veteran outfielder Eli White for minor league pitcher Tyler Uberstine, providing needed right-handed hitting depth in the outfield and earning high marks (Grade: A-).
• Trading Marcelo Mayer to the Giants for reliever Erik Miller and prospect Carlos Gutierrez surprised fans but added valuable bullpen strength and future potential, though it sacrificed a promising shortstop (Grade: B+).
