I'd say they're all available. Payamps is a vet who threw 17 pitches today and 14 the day before. I'd almost guarantee if they need him tomorrow, he's available. Ross threw 12 pitches today and had yesterday off. Can't see any reason at all that he wouldn't be available.
The only one I could actually see maybe not being available is Civale just because asking him to go in 1 day of rest after a multi inning relief appearance is definitely changing his role up significantly, especially for a guy used to starting. But push comes to shove, if he feels fine and they need him, who knows.
Now of course they probably have certain guys they'd "like" to have off if they can help it, but this is an October elimination game. Regular season rules are out the window. All hands on deck.
