First and foremost, it is important to understand the strengths and weaknesses of the Mariners farm system. For example, one would consider the outfield as a strength for the team. With players such as Jared Kelenic, Julio Rodriguez, Luis Liberato, Kyle Lewis, Jake Fraley, Dom Thomson-Williams, Braden Bishop and plenty of others in the mix, there isn’t much of a need out in the grass for the Mariners.
Therefore, it’s unlikely that they would add an outfielder with at least the first pick. Of course, that doesn’t mean that they won’t if a player they like falls to them.
