This is one of those small moves that could help us in the long run. Berroa can play 3b/ss/2b and has some pop in his bat, but has been basically thrown in the trash pile by the Royals. He's 29 and would be a better bench option than Castro. we could probably land him pretty cheap, but instead I would prefer to go this route instead:
Reds trade: Todd Coffey, BJ Symanski, and Brad Salmon
Royals trade: Angel Berroa, and Joel Peralta
KC gets two hard throwers in their pen, and an OF prospect that may or may not pan out, while the Reds get a replacement for Castro and an arm for the bullpen for the 7th-8th inning thoughts?
