The Seattle Mariners’ offseason to-do list is pretty straightforward: solve first base for the long haul (with a strong lean toward re-signing Josh Naylor), find a real third base answer to replace Eugenio Suárez, reinforce the bullpen with a trustworthy left-hander, and decide what to do at backup catcher.
That’s the board. And right as Seattle stacks those priorities, the market quietly offered a piece that can check multiple boxes without forcing a prospects-for-rentals trade. Ha-Seong Kim, newly back on the open market, represents an efficient way to stabilize third while preserving flexibility everywhere else on the dirt.
