The Red Sox acquired catcher Brent Rutschman from the Orioles at the deadline, addressing a long-standing weakness behind the plate. Boston gave up prospects to land one of baseball's best young catchers, a move that signals serious postseason ambitions despite their middling regular season record.
The Mets dealt closer Edwin Diaz to the Cubs, a blockbuster that reshapes both bullpens heading into October. New York gets younger assets and flexibility. Chicago adds a dominant late-inning arm to protect leads, something the Cubs desperately need.
The trade market moved quickly this year. Teams knew what they wanted and acted. Rutschman changes Boston's offensive ceiling. The Diaz deal gives the Cubs a legitimate shot at closing out games they should win.
Both moves carry risk. Rutschman has injury history. Diaz performed unevenly down the stretch last season. But these are the kinds of bets contenders make when they believe they can win now. The Red Sox and Cubs both committed real capital to their rotations and bullpens, banking on October baseball.
