Wang Xinyu reaches round of 16 at Australian Open for first time

Wang Xinyu ensured that China will continue to be represented in the round of 16 in the Australian Open women's singles draw, following a statement win over Czech 13th seed Linda Noskova in straight sets on Saturday.

The tournament's seventh day started an hour earlier than usual due to stifling heat. Play eventually needed to be suspended across Melbourne Park in the early afternoon, as temperatures soared to 40 degrees Celsius.

Wang's 7-5, 6-4 upset of Noskova was disrupted for several hours after being halted with the two players knotted at 2-2 in the first set.

The 24-year-old from China remained unaffected, however, and maintained her aggressive form to set up a last 16 battle with American fourth seed Amanda Anisimova.

"It's amazing. I feel like I have so much support here. It was tough, but I'm really happy to win," Wang said.

The World No. 46 is China's highest-ranked player in Melbourne after Zheng Qinwen, a former Australian Open finalist, withdrew ahead of the tournament.

Wang has been living up to her billing after reaching a second career final earlier in January, heading into the new season's first Grand Slam on the heels of a runner-up finish to Elina Svitolina in Auckland.

On the men's side, Novak Djokovic kept setting tennis records with his 400th overall Grand Slam match win and 102nd victory at the Australian Open, after beating Botic van de Zandschulp of the Netherlands 6-3, 6-4, 7-6 (4) in the third round.

The 24-time major champion became the first player to reach 400 wins in Grand Slam singles action and improved his record to 102-10 at Melbourne Park, pulling level with old rival Roger Federer's career haul for most match victories at the season's first major.

Djokovic has won the Australian Open 10 times, more than anyone else. At the age of 38, he's back in Melbourne aiming for a 25th career Grand Slam trophy that would make him the most decorated tennis player of all time.

"I must say, it's been a great start of the tournament," the Serbian legend said. "Last year I learned a lesson. I got too excited too early in some of the Grand Slams ... getting injured three out of four."

In other action at Melbourne Park, Stan Wawrinka's last match at the tournament was a 7-6 (5), 2-6, 6-4, 6-4 loss to the USA's Taylor Fritz.

After becoming the first man aged 40 or older to reach the third round of a Grand Slam since Ken Rosewall at the 1978 Australian Open, Wawrinka played his 49th five-set match at a major, also a record.

"Normally we talk on court after a final. Today is not a final, so I won't make it too long," Switzerland's three-time Grand Slam champion said. "Thank you for the wildcard invitation … to have one last chance to say goodbye to the people in Melbourne. It was my last time as a tennis player here, unfortunately. I had so many emotions here the last 20 years. I'm sad to leave, but it's been an amazing journey."
