So far, most rumors surrounding a possible Seattle trade have focused on acquiring an infielder, which makes sense given who they lost this offseason.

Recent reports have suggested that Seattle will rely on their in-house options at third base, a strategy the front office could also deploy for second base.
But while there are only a few true vacancies in the current roster, incremental upgrades could be made in several places.
