Marathon moment
While not in the same league as John Isner's epic win over Nicolas Mahut at Wimbledon last year, Francesca Schiavone and Svetlana Kuznetsova sealed their place in the record books with the longest women's grand slam match in the open era. The Melbourne crowd were treated to four hours and 44 of scintillating tennis and a gritty third set in which Schiavone saved six match points en route to a 4-6 6-1 16-14 victory. To put this into perspective, Schiavone's next opponent, top seed Caroline Wozniacki has spent just five and a half hours on court in her opening four matches.

A tall tale
It seems Wozniacki's new approach to the media seems to have gone to her head. Just two days after her light-hearted press conference in a bid to shrug off her 'boring' tag, Wozniacki claimed she was attacked by a kangaroo in Sydney last week. "It was lying there so I wanted to go over and help it out," she claimed. "As I went over to it, it just started to be aggressive and it actually cut me. But I learned my lesson and I just started running away". However, she later admitted she had just been having a bit of fun: "The kangaroo story, I made it up because it sounded better than what actually happened. I walked into the treadmill," she admitted. "That's my blonde. I'm sorry if I caused an inconvenience. I really didn't mean to. I didn't think you would believe it."

Serving up a cracker
Simply holding serve seems to be the crux of winning a tennis match - if you can guarantee to win your service games you'd give yourself a pretty good chance against anyone. Not content with simply winning his service games, defending champion Roger Federer didn't concede a single point on serve in the opening set of his 6-3 3-6 6-3 6-2 win over Tommy Robredo. Not bad, even for the great man.

Audience participation
The women's draw lost one of its real grunters as Na Li knocked out Victoria Azarenka, but not before the Aussie crowd had a bit of fun at the Belarusian's expense. As Azarenka sat down for her first break, an impersonator in the stands let out a pitch-perfect grunt that brought laughs from the rest of the crowd. Even Victoria must have appreciated the quality of the delivery - the jokester only had one shot - and they nailed it!

Dancing queen
Andy Murray pumps his fist, Maria Sharapova blows kisses to the crowd, Mikhail Youzhny favours the salute - but perhaps the most original match-winning celebration is that of No. 30 seed Andrea Petkovic. The German continued her stunning run in Melbourne, seeing off a misfiring former champion Sharapova in straight sets, and after impressing the crowd with her footwork on the court, produced her signature dance to celebrate sealing her place in the quarter-finals. Can she dance her way through another upset against No. 9 see Na Li?

Eye didn't cheat
Novak Djokovic cruised into the last eight with a 6-3 6-4 6-0 win over Nicolas Almagro, but he was given a rap on the knuckles for a code violation in the second set. The third seed was sanctioned by chair umpire Fergus Murphy after Djokovic glanced up at his supporters in his box, and Murphy felt cause to warn the Serb, believing he had received advice from coach Marian Vajda after fluffing a forehand. "I turned to my coach as you always make as a player an eye contact with your team," Djokovic admitted. "But I didn't ask for any advice, you know, because they can't help too much. You've got to do what you got to do. "
