MELBOURNE — It was very much business as usual for Novak Djokovic and Serena Williams at the Australian Open on Monday, even if allegations of widespread match-fixing cast a shadow over the opening day of the year's first grand slam.
As the sun shone and more than 70,000 fans streamed through the gates at Melbourne Park, the great and the good of tennis officialdom filed into a room in the bowels of Rod Laver Arena to defend their record on battling corruption.
On the pristine blue showcourt only a few meters away, however, first Williams, then Djokovic gave notice that they had no intention of relinquishing lightly the dominance they exerted over tennis last year.
