Flash Gordon might be the best bet for the Reds to improve there bullpen. He has been very effective as the Phillies' closer and is third in the NL with 21 saves and a 2.12 ERA. The Phillies are out of it so maybe they'd be interested in moving him and his three year $18 million dollar contract.
How about Chris Denorfia, Ryan Wagner, and Travis Chick for Gordon and Rheal Cormier.
The trade adds depth to the pen as Cormier has been pretty effective this season but is about a hundred years old and can't be in the Phillies future plans.
