Andy Murray set to rally to his cause

Hewitt, who played his first Australian Open in 1997, never achieved his ambition of winning the national championship.

Stepanek took a 4-2 head-to-head edge into the match, although Wawrinka has now won their last three matches.

Konta will now face the Czech Republic's world number 66 Denisa Allertova, to whom she lost in three sets in the French Open first round previous year.

Murray remembered being "in a bit of trouble" against Sousa at Roland Garros.

The veteran lefthander was beaten 4-6, 6-3, 6-3, 7-6 (4) on Thursday by Dudi Sela of Israel.

After his second-round win, he was asked about an Italian newspaper report casting doubt over his performance in a match against Fabrice Santoro in Paris in 2007.

Meanwhile, Chardy made 39 unforced errors to hand Kuznetsov a third-round place. There was nothing he could do, though, about Murray's 10th and final ace.

After following up his opening win over Alexander Zverev with an impressive 6-0 6-4 6-1 victory over the big-serving Sam Groth, Murray will face a very different challenge tomorrow against Portugal's Joao Sousa.

The two players, Richard Gabb and Scott Clayton, were confronted at a tournament in Turkey two years ago by Russian player Andrey Kumantsov.

Hewitt won the U.S. Open in 2001 and Wimbledon the following year.

Two-time Australian Open champion Victoria Azarenka too continued the incredible start to her 2016 title campaign, notching a swift win over Montenegro's Danka Kovinic to advance to the third round. "But I can get better, for sure".

She beat Alison Van Uytvanck 6-0, 6-0 in the first round at Melbourne Park.

"I had a bad serving day against the No. 2 player in the world and that's probably not going to cut it", he said. I was really shaking, because the sound of the lady falling was really loud. "It keeps me focused".

Azarenka is seeded 14th but on form is shaping as Serena Williams' biggest challenger at Melbourne Park. The four-time Australian Open champion, playing his 65th consecutive major, advanced 6-3, 7-5, 6-1 over Alexandr Dolgopolov.

Elsewhere Konta followed her stunning victory over Venus Williams with a 6-2 6-3 win over China's Zheng Saisai.

Prior to their second-round match in Melbourne, his opponent Sam Groth quipped: "Be nice if his wife went into labor overnight".

Isner lost to Lopez in the third round in 2012. Not among them was perennial upset victim Ana Ivanovic, although there was some drama in her win over Anastasija Sevastova.

As for Jamie, he is in the second round of the doubles with new Brazilian partner Bruno Soares after they beat Sheffield's Johnny Marray - his co-habitant - and Pakistan's Aisam Ul-Haq Qureshi 6-3, 6-4.

The 24-year-old has had problems in the past controlling her composure on court but says she is enjoying the extra tension as she goes deeper in the draw.

Play was suspended on Rod Laver Arena early Thursday when a spectator fell on a stairwell in the upper level of the 15,000-seat stadium. "It's always a pleasure to play on this court". In 2008, he played Marcos Baghdatis in a third-round match that started before midnight and finished at 4:34 a.m. There was still a big crowd in Rod Laver Arena when he won it.

The Australian began to get his game together but Murray still grabbed his fifth service break to take a two sets to love lead when Groth's crouching volley was wide on break point.
