first preference is going to be to get something for the position player who must go when Doo is ready, so no DFA / waiver / release yet. Work on a deal. 6 man bench is not stable in the modern, 5 man rotation, heavy bullpen usage era.
They are rolling the dice a bit with a 6 man pen against the Braves, but with Stras, Gio, and Scherzer, they are hoping for 2 deep starts. If either Miller or Grace has options (I forget), they may get sent down for Solis if they have to pitch long in either the Gio or the Strasburg starts.
