Australian Open: Naomi Osaka out to Amanda Anisimova

Japan's Osaka, 24, was beaten 4-6 6-3 7-6 (10-5) at Melbourne Park.

Unseeded Anisimova, 20, will play Australian top seed Ashleigh Barty in the last 16.

Barty has still not dropped a set this week after a 6-2 6-3 victory over Italy's Camila Giorgi.

The 25-year-old Queenslander is carrying the hopes of a nation desperate to see a home Australian Open champion for the first time since Chris O'Neil in 1978.

Most expected Barty to face Osaka in the last 16 when the draw pitted two of the game's biggest stars in the same section.

Novak Djokovic flies out of Australia after court throws out visa challenge

Immigration Minister Alex Hawke announced on social media that the world's number one men's tennis player had left the country.

His flight out of Melbourne ended a dramatic 11 days in which the Serbian had his visa to Australia revoked twice.

The second time came when Hawke used his powers as Immigration Minister to cancel Djokovic's visa, after lawyers for the world number one overturned the original decision by Australian Border force.

A judicial review of Hawke's decision to cancel the Serbian's visa was heard by the full bench of the Federal Court on Sunday.

Novak Djokovic focused on Australian Open after winning court ruling

The 34-year-old Serb said he practised on court in Melbourne within hours of leaving an immigration detention hotel.

But Australia's immigration minister still has powers to re-cancel the visa and deport the unvaccinated player.

"Despite all that has happened, I want to stay and try to compete in the Australian Open," Djokovic tweeted.

The statement continued: "I remain focused on that. I flew here to play at one of the most important events we have in front of the amazing fans."

Novak Djokovic will compete at Australian Open with medical exemption

The tournament begins in Melbourne on 17 January.

"I've spent fantastic quality time with my loved ones over the break and today I'm heading down under with an exemption permission," the 34-year-old said on Instagram on Tuesday. "Let's go 2022.

"I am ready to live and breathe tennis in the next few weeks of competition."

Nadal and Barty into Australian Open fourth round as crowds banned

Barty overcame a stumbling start to claim a 6-2 6-4 victory over Ekaterina Alexandrova at an empty Margaret Court Arena on Saturday.

The 24-year-old would have expected the backing of a fiercely partisan crowd for a weekend evening match at her home Grand Slam, but Melbourne's five-day lockdown left her playing in front of officials, ballkids and coaches.

While most other players have seen plenty of empty courts on the WTA tour over the last year, it was a new experience for Barty, who elected to stay home while the COVID-19 pandemic raged around the world.

Djokovic, Federer and Ash Barty through to quarters

Djokovic continued his imperious progress through the men's draw, negotiating a potentially tricky encounter with Diego Schwartzman 6-3 6-4 6-4 to reach the last eight at Melbourne Park for the 11th time.

The seven-times champion only added to a strong feeling around the tournament that the Serbian is again the man to beat at the year's first Grand Slam as he ousted the Argentine in just over two hours at Rod Laver Arena.

Federer, chasing a record-extending 21st Grand Slam, came from behind to beat Hungarian Marton Fucsovics 4-6 6-1 6-2 6-2.

Injured Nadal out of Aus Open

Former US Open champion Cilic produced a hugely impressive display on Rod Laver Arena, his stinging, flat forehands a particularly potent weapon throughout a contest that was brought to a premature end after three hours and 47 minutes.

However, the Croatian was significantly aided by a clear deterioration in the fitness of Nadal, whose movement was compromised after he called for a medical timeout in the fourth set.

Chung shocks Djokovic to advance

Former world No 1 Djokovic, who has been playing with a sleeve over the troublesome elbow that sidelined him for six months, paid the price for a lack of competitive tennis as he suffered a 7-6 (7-4) 7-5 7-6 (7-3) defeat to relentless 21-year-old Chung.

Meanwhile, unheralded Sandgren added to his earlier victory over 2014 champion Stan Wawrinka by crushing fifth seed Dominic Thiem's hopes in five sets.

Nadal marches on in Melbourne

World No 1 and top seed Nadal took the opener before dropping a set for the first time in the tournament as 24th seed Schwartzman levelled the contest via a second set tie-break.

However, it was the Spaniard who claimed the quarter-final place on offer, closing out the match, despite typical belligerence from his Argentine opponent, with a 6-3 6-7 6-3 6-3 victory.

Also into the last eight is world No 3 and ATP Finals winner Grigor Dimitrovwho beat home favourite Nick Kyrgios in four sets.

Halep survives after Davis epic

The world No 1, who had won the pair's only previous meeting at Indian Wells in 2013, has endured her travails in the opening week in Melbourne, she suffered an ankle injury in her first-round victory, but remains in with a chance of a maiden Grand Slam title.

Halep, 26, served for the match on three separate occasions in the decider but was pushed all the way by her unseeded American opponent in a 4-6 6-4 15-13 victory, which lasted three hours and 44 minutes.
