The Tigers are dangling setup man Fernando Rodney, hoping to acquire a better closer. Jon Paul Morosi believes the Tigers might aim for a reliever they control for a year or two, as their in-house options should be ready by 2010.
Rodney got hit hard when he first came back from the DL, but was very good after that. He had control problems, but that could be a result of coming back mid season from an injury. I think between him and Burton, either one would be just as good as Cordero as a closer and a much better value. Switching leagues could definitely help him.
There would have to be more to the deal to make up the difference in salary, but it is worth looking into IMHO.
