The MLB offseason has officially begun — and the Mariners kicked it off by locking up Josh Naylor on a five-year deal. Adam Weinrib and Robert Murray break down what comes next for Seattle, whether other first base–hungry teams have to pivot, and how this sets the tone for the winter.

They also dive into the early-moving relief market, with names like Raisel Iglesias, Edwin Díaz, and José Alvarado surfacing in trade and signing chatter. Plus: the Phillies’ bullpen depth, Royals-Cardinals trade buzz around Kris Bubic and Brendan Donovan, and what kind of moves the Cardinals might make to reshape their roster.
