While you can make the argument Riley needs to go down and get everyday ABs, platooning him with Shaw could make sense - especially if they believe there's a bounceback coming for Shaw. Drop Duvall and use the money saved to pay Shaw - Riley becomes Shaw's platoon-mate, gives Freddie more rest than Snitker's been giving him, and becomes your primary pinch-hitter against lefties. Sign Ozuna to hit behind Freddie and Markakis becomes your primary pinch-hitter against righties. Bring Joyce and Hechavarria (or Jose Iglesias) back to fill out the bench. You've upgraded the bench (Joyce and Riley instead of Duvall and Culberson), maintained Snitker's precious L/R balance in the middle (Freeman/Ozuna/Shaw/d'Arnaud), and kept the Waters/Riley/young arms powder dry in the event AA can swing a deal for an Ace.
