Given Lewis' injury history, it's likely he gets the Buxton treatment of playing the field 4-5 times per week, max.
Lots of room.
Who goes to AAA? This is overly dismissal, but does it matter that much? Twins Daily acts like every transaction is final when, in truth, there will be a second promotion/demotion of another player within a week.
I personally don't think it will be Margot, since his whole purpose on the team is to play OF and neither Miranda nor Lewis does. And if they do cut Margot, I predict they make a second move within the week and promote somebody who plays OF.
