Per Marc After The Game:
MILWAUKEE -- Following the game, the Reds optioned Justin Germano back to Louisville.
Narron said Germano was going back no matter how he pitched, so there obviously is something going on here. The fifth starter's spot won't be needed again until next Saturday, if my math is correct. That start could go to Brandon Claussen, who would be on regular rest if he makes his Monday rehab start as scheduled, and the Reds could use the roster spot in the meantime for another bullpen arm or bench help.
Still, as conservative as the Reds tend to be with rehab assignments and seeing how things play out, I'm surprised they would commit to a schedule like that without knowing how Claussen performs Monday. Which raises the possibility that a trade is in the works. I don't think that would surprise anyone, though I haven't heard anything specific today.
I'm sure it'll all become crystal clear by tomorrow, but this one's got me a bit confused at the moment.
