DSG I think was brought in for his versatility, so I imagine he may stay a while. They are going to need to add a position player by 6/19. You could see them doing a gimmick and keep Adrianza and Escobar on the IL until then, then add back one. I see Thomas as the 4th OF. Without him, the only pop off the bench is Adams.
Just spit ballilng - bench of Adams, Thomas, DSG, and one of Adrianza or Escobar when the team must carry no more than 13 pitchers. Adrianza will also involve removing someone from the 40 man roster, and Voth and Sanchez are gone already. Stras does not need to bump anyone because he was never put on the 60 day IL.
