Who is first up after Nate?
Depends on where they are in the game, I think.
Sawamura, Whitlock, and Taylor are possibilities. I think we won't see Matt Barnes until later in the game. Ditto Ottavino.
If the game is tight and it has gone smoothly into the 6th or 7th, I don't expect Garrett Richards. Robles may well make an appearance in the 9th.
