Littell looked really good. Arreaz has looked really good.
Adrianza has performed the worst, but he has been steady and solid.
Astudillo's bat has been flagging for a while. But he continues to be an asset to the team.
With Duffy's new veliocity and his usual awesome breaking balls, how could you possibly send him down?
Gun to my head, I would choose Adrianza or Arraez, and probably Littell. I would not be happy about it.
I suspect it will actually be Arraez and Littell.
Good problem to have, GREAT problem to have, but this just plain sux.
