First, there are the guys already getting a look-see. Dickerson has a good chance. Wilkin Castillo good chance as a 25th man type. Ramon Ramirez will likely compete for a long relief spot, maybe with Nick Massett. Hanigan should be with the Reds. Rosales (now back at AAA) would seem a possibility to ride the interstate between AAA and Cincy next year.
Next, the guys at AAA. Main area is bullpen. Herrera and Pelland from left side; Roenicke and Fisher from the right side. I doubt that most will be at Louisville next year. One or more may be traded. One or more may be Reds, or at least will get a real shot in the spring.
Homer or Maloney? I don't see either of them starting out with the Reds out of spring training next year. (Maybe Homer breaks through next year and comes up when a starter is injured or struggles.)
Micah Owings -- expect him to compete for a long relief or fifth starter spot with the Reds. Massett, Ramirez, Owings gives the Reds some new depth in that area.
AAA position players. IMO Janish will either be on the Reds' bench next year or gone. I've been a big supporter, I'd like to see him on the Reds' bench as a defensive utility guy.
Danny Richar? My guess is he gets a spring look-see and could hang on, but only with a great spring.
Stubbs? Probably starts at AAA next year. Cumberland? AAA to begin.
AA players? I don't think any have serious chances to make the Red since the team has aggressively moved them up to AAA if near ready. If Valaika or Turner move to AAA and do well, either could be an early call up.
