As Tuesday's Australian Open match between Andy Roddick and Novak Djokovic was nearing an end, and Djokovic was moving around the court with the grace of a dump truck, the ESPN commentators asked an open question about the Serb's conditioning: "What will his peers say off the record?"It was the Serb's fourth retired match in a Grand Slam, and Djokovic (right) is only 21. Also, coincidentally, Roddick had called out Djokovic for being a little bit of an injury-milker at the U.S. Open last year, so this issue has been raised before. Well, no less an authority than Roger Federer spoke about the matter, and it wasn't off the record. He flat out said Djokovic needs to do something to be more fit.
