According to that story on Reds.com, the rumored call ups will be: Ramirez, Coffey, Herrera, Bailey, Livingston, Janish and Richar. Maybe Drew Stubbs.
A move would have to be made for the 40-man roster, but Maloney and Pettyjohn are also candidates.
Personally, I'd just say no to Pettyjohn, Richar, Janish, Bailey, Coffey, and Livingston. The guys I'd like to see aren't on the 40 man yet.
