Triston Casas

The Mariners have also approached the Red Sox about trading for Triston Casas, so they appear to be serious about upgrading at first base this off-season. For the Guardians, trading Naylor makes sense if they are getting a big enough return. The 27-year-old is set to be an unrestricted free agent after this season and may be out of Cleveland's price range. The team could look to trade him now when they are likely to get more in return than if they waited for the trade deadline. With Kyle Manzardo on the roster, the team also has a built-in replacement at first base, so this is a situation that's worth monitoring.

The four biggest names when it comes to free agent first basemen are Pete Alonso, Christian Walker, Paul Goldschmidt, and Carlos Santana and all of them carry significant concerns. For starters, Alonso is the youngest of the bunch at 30 years old. It seems that none of them four are yet willing to lower their asking price or the number of years they're looking for, and teams are willing to wait them out rather than commit lots of money over a long-term deal to the aging power hitters. Complicating factors is also that teams still believe all of Triston Casas, Josh Naylor, and Lamote Wade Jr. could be had in a trade, so teams are willing to wait and see how that plays out as well.

Morosi doesn't specify which one of Seattle's arms the Red Sox are targeting. However, The Seattle Times' Adam Jude notes that the two sides have engaged in trade talks this offseason before adding that a Luis Castillo for Triston Casas swap would make sense for both sides. It doesn't sound like anything is imminent, but it's a developing situation fantasy managers should monitor following the Winter Meetings.

The Mariners’ pitching depth over the last few seasons has drawn many teams into trade talks and it was almost exactly a year ago that reports surfaced about Boston’s interest in the Seattle rotation. Nothing materialized between the two teams then, but Ryan Divish and Adam Jude of the Seattle Times report that earlier this…
