The Seattle Mariners aren't being cute about how they want to fill their hole at first base. Josh Naylor was the guy they had at the end of 2025, and Josh Naylor is the guy they want to be there in 2026 and beyond. It's not rocket surgery.
And yet, it doesn't take much to imagine dominoes falling in such a way that the Mariners are forced to take another look at Boston Red Sox slugger Triston Casas.
The Mariners had to seriously consider Casas last winter, precisely because the Red Sox asked them to in trade talks centered on starting pitching.
