Fay later says a reliever will be brought up, to replenish the bullpen, but I'm not sure who would it would be, or who would be sent down. Maybe Fisher up, Smith down. Just a guess.–The Reds just announced that Russ Springer had surgery today for a herniated disk. He is done for the season. That opens a 40-man spot. Wladimir Balentien could be added and be here for tomorrows game.
Also, would have been nice to know this before they lost Ownings. Oh well.
