From ctrosecrans:
Today the Reds signed David Ross to a two-year deal plus a club option for 2009, avoiding arbitration with the catcher.The team also reached a minor league deal with Paul Wilson, who was also invited to major league camp.
I like this. Even if Ross falls off a cliff I think he'd make a fine backup, which I think mitigates the risk a little. His power alone makes him a solid offensive option for the position.
I'm going to assume the Reds are just being loyal to Wilson, and that's not a bad thing. Maybe he'll be able to help out of the bullpen or something, but I wouldn't count on it.
