Nadia Petrova stunned the Rod Laver arena audience into silence as she dismantled reigning US Open princess Kim Clijsters, 6-0, 6-1. Clijsters played poorly throughout, but Petrova deserves credit for playing a magnificent match when it mattered most. Nothing seemed to go right for the Belgian and this is a big setback in her climb back into the top ten. For Nadia Petrova, she will now go into a match against Svetlana Kuznetsova in full confidence of causing another upset.
Kuznetsova was a set and a break down in her 3rd round match with qualifier Angelique Kerber, before battling her way to victory in 3 sets, the winning scoreline reading 3-6, 7-5, 6-4. Sweating profusely, she showed why she is a Grand Slam champion by turning around this match as it was beginning to slip away.
In the mens draw, Rafael Nadal encountered an intense match with German Philip Kohlschreiber, who was going for winners all over the court. Nadal fought out the first two sets, but Kohlschreiber's persistence was repayed when he pulled one back. However, Nadal also put on a powerful show and emerged with the victory in 4 sets to set up a clash with Giant Croat Ivo Karlovic.
Andy Roddick and Fernando Gonzalez both won and will meet in a mouth-watering clash in the last 16. Andy Murray enjoyed another easy win and big-serving American, John Isner, overcame the charismatic Gael Monfils of France. Murray and Isner will meet in the last 16 in what should be the Scot's first big test in Melbourne.
Sadly, Britain's Elena Baltacha came to the end of the road when she was comprehensively beaten by Dinara Safina, who herself has been quietly making her way through the draw, as she looks for her first Grand Slam title.
