One possibility is that they have another trade they can make involving righthander Jon Lieber that would bring an outfielder in return. Another would be that the talks with San Diego would be expanded with Lieber being packaged with Rowand and the Phillies also receiving an outfielder (maybe Sledge or Mike Cameron).
I don't see the Padres giving up Mike Cameron for Jon Lieber. We need to hold on to what little offense we have at this point. Our starting rotation and bullpen look good. I don't think adding Lieber would sweeten the deal for the Pads.
