Sign a right-handed hitting outfielder
This one is a little complicated if the Twins end up bringing back Michael A. Taylor, as it could create a redundancy. If the Twins re-sign Taylor, though, he'll once again provide depth in center behind Byron Buxton -- who is expected to play a lot more than he did last season.
Minnesota would still have a need for corner outfield depth, but would also need someone who could provide more power hitting than Taylor. This branches the debate off into a few different possible directions.
Let's say the Twins do bring Taylor back. He's a right-handed hitting option, but one who lacks the power that someone like Adam Duvall might be able to bring. Duvall has plenty of offensive issues he needs to work through, but he's more of a traditional slugger than Taylor plus he can play either corner of the outfield.
If the Twins don't being Taylor back, that creates an even bigger need to find right-handed hitting. Austin Martin is expected to be on the Opening Day roster, but it's unclear where he'll spend the majority of his time. While he's capable of playing center and provides an alternative to Taylor, he might play the infield more than he does outfield.
Duvall becomes an even more intriguing option with the second scenario, but he's by no means the only right-handed hitting outfield option. Tommy Pham, Clint Frazier, and Enrique Hernandez would all be potential fits as well.
