Melbourne's worst heatwave in more than 100 years played havoc on Tuesday as defending champion Novak Djokovic joined the list of casualties. Djokovic pulled out of his quarterfinal with Andy Roddick looking pale and sickly after two-and-a-half hours of toil in hot and muggy conditions with the mercury rising to 35 C (95 F).
The dramatic withdrawal comes a day after Belarus's Victoria Azarenka pulled out in tears after falling ill during her match with Serena Williams. Azarenka, who was a set up, was staggering around crying before she gave up playing and was helped from the court. "Conditions were extreme today. It did affect me more than him, as you could see," said Djokovic.
Dokic makes mum proud
The mother of Australia's Jelena Dokic spoke of her pride at her daughter's return to big-time tennis but revealed the troubled player is still sometimes "sad" when they speak. "I am very proud of my daughter, I'm very proud she's come back," Liliana, now reconciled with Jelena, said. "I always expect my daughter will win."
