It’s no secret that the Seattle Mariners desperately need an everyday first baseman and a hefty righty to support Julio, JP, and Cal in the lineup. While the Mariners still have the option to bring back Justin Turner, and I think he would be good to keep around, they should prioritize signing Pete Alonso, whom the Mets seem ready to move on from after he reportedly turned down a three-year deal. Seattle has been linked by national reporters to Alonso all winter, and while it seems like a longshot given the club’s unwillingness to try and win on anything other than hard (cheap) mode, the fit is easy like a first baseman’s glov-, er, mitt.
