Tsk, why are people bothering with these clownish Djokotards. Let me get this thread back on topic.
I reckon Fed might take a WC in MC after all. He (apparently) hasn't lost as early in Miami since 2004 and in his preliminary schedule he had DC (they may have beaten the US after all). So all in all, he excluded MC because he would have had a total of one week's rest. Now he has had 3. It'd be interesting to see how Fed decides to proceed from here.
However, if he plays, it means he's feeling well so the retrieving duo better watch out
