They aren't DFA'ing Richards after one start, so when ERod is back, I think they will.
They will also likely gain an extra year of team control by keeping him in AAA for a few weeks.
He looked real good, last start, so I can understand keeping him around, but Pivetta & Eovaldi looked good, too.
If Perez sucks, tonight, there will be a more heated debate about demoting Houck.
