I don’t see Yelich being DH more than occasionally.
To get their best lineups they need to use that spot some times to keep Contreras’ bat in when he gets days off from catching, and to keep Hoskins from playing 1B every day.
Frelick would get his playing time when Yelich, Contreras, Hoskins, Chourio or Perkins get complete days off. But for now I think Perkjns should be ahead of Frelick in the pecking order.
