Rafael Nadal survived a fourth-round test at the Australian Open, but Daniil Medvedev fell to Stan Wawrinka in Melbourne on Monday.

Nadal overcame Nick Kyrgios in a huge battle on Rod Laver Arena, reaching the quarter-finals at the year's first grand slam for the 12th time.

The man he conquered in last year's US Open final, Medvedev, fell short in a five-set thriller against Wawrinka.

Meanwhile, Alexander Zverev's impressive run continued and Dominic Thiem also advanced to the last eight.

 

NADAL GETS PAST KYRGIOS

Nadal needed three hours, 38 minutes and a fine performance to edge past Kyrgios 6-3 3-6 7-6 (8-6) 7-6 (7-4).

The world number one, who has endured a frosty relationship with the Australian, hit 64 winners and made just 27 unforced errors in his win.

A visibly emotional Kyrgios warmed up for the blockbuster clash in a Kobe Bryant jersey, paying tribute after the Los Angeles Lakers great's death on Sunday.

The 23rd seed fought hard as the pair put on a show, but was left to rue costly errors in the two tie-breaks.

Nadal will face Thiem, who powered past Gael Monfils 6-2 6-4 6-4 in under two hours, as the Spaniard's bid to join Roger Federer on 20 grand slam titles continues.

Thiem, 26, reached the quarter-finals of the Australian Open for the first time.

 

RESURGENT WAWRINKA OVERCOMES MEDVEDEV

Champion in Melbourne in 2014, Wawrinka produced what was the only upset of the day – at least by ranking – as he eliminated Medvedev.

The Swiss three-time grand slam champion claimed his first win in three meetings with the Russian fourth seed, winning 6-2 2-6 4-6 7-6 (7-2) 6-2.

After failing to go beyond the third round of any major in 2018, Wawrinka reached two quarters in 2019 and is into the last eight in Melbourne for the first time since 2017 – the year he underwent knee surgery.

The loss saw Medvedev fall to a 0-6 win-loss record in five-setters in his career.

"As I say, I don't like to play five sets," he told a news conference. "I get tired. Even though I'm there, I want to win it. As I say, at this moment, didn't win one in my life. We'll try better next time."

 

ZVEREV'S CLASSY RUN CONTINUES

Next up for Wawrinka is Zverev, who is yet to drop a set after impressively brushing past Russian 17th seed Andrey Rublev 6-4 6-4 6-4.

Zverev, the German seventh seed, did not face a break point on his way to the Australian Open quarter-finals for the first time.

It also marked the first time Zverev has reached the quarters at a major other than the French Open, where he lost in the last eight in 2018 and 2019.

"He showed why he's a grand slam champion, beating Medvedev, coming back from two sets to one down, playing great tennis," Zverev said about Wawrinka.

"He's still one of the toughest players to play, especially here in Australia."

Rafael Nadal encouraged Nick Kyrgios to continue with the same attitude he showed at the Australian Open after the Spaniard won their fourth-round clash on Monday.

World number one Nadal survived a test against Kyrgios, reaching the quarter-finals courtesy of a 6-3 3-6 7-6 (8-6) 7-6 (7-4) win on Rod Laver Arena.

The pair have endured a frosty relationship in the past but were largely respectful throughout, while Kyrgios' latest performance looked another step in the right direction for the volatile Australian.

Nadal said the 24-year-old was one of the best players on the ATP Tour and needed to continue with his improved attitude.

"What can I say again about Nick? When he's playing like today with a positive attitude, he gives lots of positive things to our sport," the Spaniard said in an on-court interview.

"I encourage him to keep working like this because he's one of the highest talents we have on our tour.

"I like the Nick Kyrgios of this tournament."

Kyrgios had warmed up for the clash in a Kobe Bryant jersey after the Los Angeles Lakers great's death.

Nadal also paid tribute to Bryant, who died alongside his 13-year-old daughter Gianna and seven others in a helicopter crash in Calabasas, California on Sunday.

"He always wanted more, he always wanted to increase his level," he said.

"He was a true inspiration for the world of sport and for a lot of kids, so it's one of these days that you want to forget.

"But of course, Kobe Bryant will be in our hearts and minds for the rest of our lives."

Rafael Nadal survived a test from Nick Kyrgios to move into the Australian Open quarter-finals with a four-set win on Monday.

The world number one was pushed by Kyrgios on Rod Laver Arena before completing a 6-3 3-6 7-6 (8-6) 7-6 (7-4) victory after three hours, 38 minutes in the fourth round.

Nadal produced the strong performance he needed to overcome the talented Australian, who warmed up in a Kobe Bryant jersey to honour the Los Angeles Lakers great following his death on Sunday.

The Spaniard remains on track to match Roger Federer's men's record of 20 grand slam titles after reaching a 41st major quarter-final and 12th in Melbourne, where Dominic Thiem awaits.

Nadal would land the first blow of a high-quality start in the fourth game.

Highlighted by a ripping forehand passing winner, Nadal broke for 3-1 in an error-riddled game by Kyrgios, including two poor drop shots.

The first set belonged to Nadal in slightly windy conditions, the single break and 14 winners helping him take it in 36 minutes.

Nadal was booed as he made Kyrgios wait to start the second set before the latter saved three break points in the opening game.

The importance of that hold was amplified when Kyrgios, pumping up the crowd after setting up break point, produced a forehand winner down the line to take a 3-1 lead.

Facing some pressure at 30-30 serving for the set, the 24-year-old delivered two huge aces to level the match.

No early blow was forthcoming in the third set, a brave drop shot from Kyrgios seeing him save a break point in the eighth game.

A tense tie-break followed, Kyrgios and Nadal trading double faults from 5-5 before a forehand error from the Australian – who also broke a racquet – gave his opponent the set.

Coming off his epic five-setter against Karen Khachanov, Kyrgios looked beaten when he was broken to love following a double fault in the third game of the fourth set.

To his credit, Kyrgios hung in there, breaking back when Nadal was serving for the match in the 10th game, much to the appreciation of the Rod Laver crowd.

Kyrgios dug himself out of a 15-40 hole in the following game as another tie-break followed, a terrible drop shot handing Nadal a 5-3 lead he would not relinquish before the pair shared a respectful handshake at the net amid what has been a frosty relationship.

Simona Halep continued her imperious form at the Australian Open as she secured a quarter-final spot at the expense of Elise Mertens.

Yet to drop a set at these finals, the fourth seed produced another commanding performance to book a meeting with Anett Kontaveit.

Garbine Muguruza felled another seed, Kiki Bertens beaten in just 69 minutes by the Spaniard, as she reached the last eight in Melbourne for only the second time.

Anastasia Pavlyuchenkova also progressed after a tense battle with 2016 champion Angelique Kerber.

 

KONTAVEIT WINS EPIC TO EARN HALEP SHOWDOWN

Beaten in their previous meeting in Doha last February, Halep had to work hard for a 6-4 6-4 victory over Mertens as she reached the quarter-finals in Australia for the fourth time.

After Mertens recovered from a 3-1 deficit to lead 4-3, Halep went on a six-game winning streak to take the opening set and move 3-0 up in the second.

Mertens rallied again to recover a double break, but Halep battled to move 5-4 ahead before serving out to love.

"Mentally, I think I did a great job today at four-all with those break points, game points," she said. "But in the end, I got the game and then I served very well the last game. I feel like I played a better match than all the matches since I'm here."

Halep now faces Kontaveit, who came through a punishing three-set clash against Polish teenager Iga Swiatek.

Kontaveit recovered to win 6-7 (4-7) 7-5 7-5 to become the first Estonian to reach the quarter-finals of a major.

MUGURUZA POWERS PAST BERTENS 

Muguruza claimed back-to-back wins over top-10 players by beating Bertens 6-3 6-3 to reach a grand slam quarter-final for the first time since the 2018 French Open.

The 26-year-old, who knocked out world number five Elina Svitolina in round three, has an eye on the big prize already after showing too much power for ninth-seed Bertens, hitting 19 winners and six aces. 

"It is very good to be back here," she said. "It is one of the grand slams that one day I would like to win. It's exciting." 

Next for Muguruza will be Pavlyuchenkova, who triumphed 6-7 (5-7) 7-6 (7-4) 6-2 over Kerber in two hours and 41 minutes. 

Having lost the first set after surrendering a double break, the Russian fought back to edge a tight second with a thumping return winner on her fifth set point.

The third set was more one-sided as Pavlyuchenkova moved 5-2 up and serving out the match with an ace.

Margaret Court received a surprisingly warm ovation during a special ceremony at the Australian Open on Monday.

The controversial 77-year-old Australian was honoured during a ceremony to celebrate the 50th anniversary of her Grand Slam, winning all four majors in 1970.

Court has previously been criticised for comments on race, homosexuality and the transgender community.

However, the 24-time grand slam singles champion was greeted by applause and cheers during the presentation on Rod Laver Arena.

She was presented with a replica Australian Open trophy by Rod Laver, who received a huge cheer.

Court remains the record holder for most grand slam singles titles, with Serena Williams stuck on a tally of 23 that she will not add to in Melbourne this year.

Another tennis great, John McEnroe, criticised Court in a video posted by Eurosport on Twitter earlier on Monday.

"It's the 50th anniversary of Margaret Court's Grand Slam, and Tennis Australia is facing a dilemma: what do they do with their crazy aunt?" the seven-time major champion said.

"They finally decided to invite her, but it came with a twist, 'we will recognise what she did in 1970, but we won't celebrate the person'.

"Huh? Well it doesn't work that way. You can't separate the person from her achievements."

Nick Kyrgios paid tribute to Kobe Bryant before his Australian Open fourth-round clash with Rafael Nadal on Monday.

The Australian, a huge basketball fan, wore a Los Angeles Lakers jersey with the number eight Bryant made famous to begin his career.

A visibly emotional Kyrgios received a fine ovation as he entered Rod Laver Arena in the jersey.

Lakers great Bryant, 41, and his 13-year-old daughter Gianna died in a helicopter crash in Calabasas, California on Sunday.

The sporting world celebrated and mourned Bryant after his shock death.

Lionel Messi and Cristiano Ronaldo were among the football stars paying their respects, while the NBA world mourned Bryant's passing.

It is getting to the business end of the Australian Open for Roger Federer, who meets Tennys Sandgren in the quarter-finals on Tuesday.

Federer banished the demons of last year's shock fourth-round exit by topping Marton Fucsovics in Melbourne on Sunday.

A 20-time grand slam winner and six-time champion at Melbourne Park, Swiss maestro Federer is eyeing his first major title since the 2018 Australian Open.

As Federer prepares for the last eight, we look at the 38-year-old's form.

 

Form and results

Like his five-setter with John Millman, Federer dropped the opening set against Fucsovics on Sunday. However, third seed Federer managed to avoid going the distance as he steamrolled his unheralded Hungarian opponent in two hours, 11 minutes. The veteran used 44 winners to vanquish Fucsovics under the Rod Laver Arena lights.

R1: bt Johnson 6-3 6-2 6-2
R2: bt Krajinovic 6-1 6-4 6-1
R3: bt Millman 4-6 7-6 (7-2) 6-4 4-6 7-6 (10-8)
R4: bt Fucsovics 4-6 6-1 6-2 6-2

Next up

Sandgren finds himself in a familiar position. The 28-year-old will contest his second Australian Open quarter-final following his 2018 run. Sandgren upstaged 12th seed Fabio Fognini in four sets on Sunday. This will be the first meeting between Sandgren and Federer.

Draw

A blockbuster semi-final against defending champion Novak Djokovic is on the horizon for Federer. Djokovic must see off Milos Raonic to make that happen. The iconic pair played out a remarkable Wimbledon final, won by Djokovic, last year.

What he said

"I'm very happy how I'm feeling considering my age, considering everything I've gone through throughout my career. The toughness of the first real tough match of the season for me after having not played these kinds of matches for some time, it's nice to see that the work I did in the off-season paid off."

Novak Djokovic's form is ominous as the Australian Open champion prepares to face Milos Raonic in the quarter-finals on Tuesday.

After a wobble in the opening round, second seed Djokovic has dominated his last three opponents en route to an 11th quarter-final appearance at Melbourne Park.

Eyeing a record-extending eighth Australian Open title, Djokovic once again looms as the player to beat in Melbourne.

We take a closer look at Djokovic as the 16-time grand slam champion prepares to meet 32nd seed Raonic on Rod Laver Arena.

Form and results

Stop Djokovic if you can. The world number two swept aside 14th seed Diego Schwartzman on Sunday. While the Argentinian proved a tougher test than Tatsuma Ito and Yoshihito Nishioka, Djokovic was far superior in the Melbourne sun. Hitting 38 winners and 31 unforced errors, the Serbian star closed out proceedings in just over two hours.

R1: bt Struff 7-6 (7-5) 6-2 2-6 6-1
R2: bt Ito 6-1 6-4 6-2
R3: bt Nishioka 6-3 6-2 6-2
R4: bt Schwartzman 6-3 6-4 6-4

Next up

Former world number three Raonic stands in the way of Djokovic and another trip to the semi-finals - a repeat of the 2015 quarter-final clash in Melbourne. Raonic blitzed Marin Cilic in straight sets to advance on Sunday. However, the Canadian's 0-9 record against Djokovic is a concern.

Draw

It is the match everyone is dreaming of. Djokovic against 20-time slam winner Roger Federer in the semis. That mouthwatering showdown could happen if Djokovic maintains his perfect record against Raonic and Federer gets past Tennys Sandgren.

What he said

"It obviously helps when you have a success on a global level. Of course, it has a very positive impact in your country. Serbia didn't really have a successful or long tennis tradition, before [Slobodan] Zivojinovic and Monica Seles. That was probably the first generation of successful tennis players coming from our country."

Rafael Nadal led tributes from the ATP Tour following the tragic death of Los Angeles Lakers great Kobe Bryant.

Bryant, 41, and his 13-year-old daughter Gianna died following a helicopter crash in Calabasas, California on Sunday, NBA commissioner Adam Silver confirmed.

Five-time NBA champion Bryant transcended basketball after his selection in the 1996 draft, going on to spend his entire 20-year career with the Lakers, where he claimed two Finals MVPs to go with his 2008 Most Valuable Player honour.

As the sporting world mourns his death, 19-time grand slam champion and world number one Rafael Nadal tweeted: "I woke up this morning with the horrible news of the tragic death of one of the greatest sportsman in the world. Kobe Bryant, his daughter Gianna and other passengers. My condolences to his wife and families. I am in shock."

Rod Laver - one of the greatest tennis players of all time with 11 major titles - wrote: "Terribly sad to wake up to this news today. RIP Kobe Bryant. Too young. Deepest condolences to family and friends of the sporting legend."

Australian Open champion Novak Djokovic had only spoken about Bryant - who attended last year's US Open - and his impact last week.

Prior to Sunday's fourth-round win over Diego Schwartzman at Melbourne Park, 16-time slam champion Djokovic provided an insight into Bryant following a difficult spell in 2018, which saw the Serbian star drop out of the top 20 due to an elbow injury.

"Kobe has been one of my mentors," Djokovic told ESPN. "I've had several phone conversations with him and also of course when we see each other live in the past couple of years. 

"When I was going through the injury with my elbow and struggling to mentally and emotionally handle all of these different things that were happening to me and dropping in the rankings and then having to work my way up, he was one of the people who was really there for me to give me some very valuable advice and guidelines to kind of believe and trust in myself, trust the process that I'll be back.

"I'm very grateful to him for being there for me, for being very supportive. I love Kobe, who doesn't? He's an amazing guy and one of the best basketball players and athletes of all-time."

Roger Federer is preparing to face an enigma when he tackles Tennys Sandgren in the Australian Open quarter-finals, and the American even admits: "Maybe I shouldn't be here."

Sandgren is the world number 100 but has an unusually strong record against top-10 opponents, scoring wins over Stan Wawrinka, Dominic Thiem, Fabio Fognini and, earlier in this tournament, Matteo Berrettini.

The 28-year-old from Tennessee only made his grand slam main-draw debut in 2017 and is, by modern tennis standards, a late developer.

In 2014, he lost a Challenger Tour match to Britain's Marcus Willis, who famously chomped on a chocolate bar and sipped a cola drink rather than elect for snacks more usually associated with professional sport stars.

That match was highlighted, raking up bad memories for Sandgren, when Willis made a name for himself in 2016 at Wimbledon, the genial home player taking on Federer in a highly entertaining but one-sided second-round match on Centre Court.

Now, though, it is Sandgren's turn to tackle the 20-time grand slam winner, and their clash should be competitive.

"I wonder why he's not ranked higher, to be honest," Federer said of Sandgren. "Every time I see him play, I feel like he plays very well. He's got a lot of stuff in his game that [means] he's deserving of being higher.

"I'm looking forward to that match because I've seen him play a lot but never played him."

Sandgren repeated his 2019 Wimbledon win over Fognini to sink the Italian's hopes over four sets in Melbourne on Sunday, and Federer took the chance to watch, predicting "a tough one" next.

For his part, Federer overcame a sluggish start to see off Marton Fucsovics 4-6 6-1 6-2 6-2, with any effects of his late-night battle with John Millman in the third round seemingly shaken off.

Sandgren was asked why he has shown himself capable of doing well on the big occasion.

"Maybe because I haven't had that many," Sandgren said. "Maybe I haven't had that many looks or wasn't supposed to.

"Maybe I shouldn't be here. The fact that I am, I get kind of amped up. I want to perform. I want to do well. I don't want to take the time on the court for granted.

"Getting to play in a big stadium, getting to play in front of a lot of people, because I've played a lot of tennis in front of very few people, that seems to bring out the best tennis in me."

Sandgren's big shot is his serve, as Federer has observed.

The Swiss has taken down many a player with a booming serve in the past, yet he has also been struck by other areas of Sandgren's game, saying: "He can counter-punch but also likes to go on the attack."

Sandgren spoke of how he spent his early years in tennis "not sniffing these opportunities" and claimed: "There are better players than me that I played with in Futures and Challengers that have stopped playing because they just ran out of money or got injured.

"There's definitely a world where it didn't work out [for me]. Some of the margins were pretty small for me to have some of these opportunities. I definitely don't take it for granted."

He was also reminded of the Willis match, which took place on an indoor court in front of a spartan crowd.

"I did not feel great after that one. He downed an RC Cola and a Snickers and took me out," Sandgren recalled. "I had a few of those where it's like, 'What are you doing? Is this ever going to be worthwhile?'"

Juan Martin del Potro will undergo knee surgery on Monday after a previous operation failed to rid him of pain, leaving the former US Open winner struggling even to walk up stairs.

The injury-blighted Argentinian suffered a fracture of his right kneecap at Queen's Club last June, a repeat of an injury he suffered in Shanghai in October 2018.

He had hoped to return to action before the end of 2019, but initial surgery did not bring results to the extent Del Potro had hoped, and he has not been able to return to the tennis circuit.

A statement from his communication team declared on Sunday that Del Potro, absent from the ongoing Australian Open, would have an operation in Miami.

The statement said 31-year-old Del Potro had taken advice from doctors in Argentina, Europe and the United States, with the majority of verdicts determining "a new intervention" in his right knee was required.

"After analysing the options, Delpo trusted Dr Lee Kaplan to perform the surgery scheduled for Monday, January 27th in Miami," the statement said.

"We hope that this is the definitive solution to eliminate the pain that not only has prevented Delpo from playing tennis, but also making it difficult for him to perform daily activities."

The statement added that pain has endured through Del Potro's attempts to get back on court, preventing him "from running and jumping, and even activities such as walking up stairs".

Del Potro, one of the most popular players with crowds on the men's tour, hoped to have been back in competition by last October.

His camp thanked well-wishers for their patience, as the statement added: "The situation is never easy when it comes to the physique of an athlete and, more importantly, the health of a person."

Tennys Sandgren will play Roger Federer in the Australian Open quarter-finals after beating Fabio Fognini in a tense affair on Sunday.

The American triumphed in four sets - three of which went to tie-breaks - to knock out the 12th seed and book a meeting with Federer, who dispatched Marton Fucsovics after a nervy start.

There were few signs of the jitters for Novak Djokovic against Diego Schwartzman, while Milos Raonic's relentless serving strength saw him power past 2018 finalist Marin Cilic.

Canadian Raonic said he felt "pretty damn good" after a straight-sets win that included 35 aces, although he admitted he will need even more to beat defending champion Djokovic next.

 

SANDGREN FIGHTS THROUGH FOGNINI FRUSTRATION

Sandgren traded winners and barbs with Fabio Fognini before prevailing 7-6 (7-5) 7-5 6-7 (2-7) 6-4 to seal his second Australian open quarter-final berth.

Tempers frayed across four entertaining sets on Melbourne Arena, with the American becoming upset at his opponent's stalling tactics.

Fognini, the 12th seed, argued with the umpire, took a lengthy bathroom break and asked for a medical timeout to treat blisters all before the third set, leading Sandgren frustrated.

"He gets his own rules because you're afraid to step on his toes," the world number 100 told the umpire after taking the opener.

Sandgren, who lost to Chung Hyeon in the last eight two years ago, regained his composure and went on to complete the upset in three hours and 27 minutes.

FEDERER FINDS FORM AFTER EARLY WOBBLE

Federer seemed to be feeling the effects of his epic five-set victory over John Millman as Fucsovics took an early lead on Rod Laver Arena.

However, the 38-year-old recovered in supreme style and seemed somewhere close to his best tennis at the end of a 4-6 6-1 6-2 6-2 victory.

As the full repertoire of shots from Federer began to paint the lines, Fucsovics had little response.

The 20-time major champion is now looking forward to a first meeting with Sandgren. "I have played a lot of tennis in my life, but never against Tennys," he said.

DJOKOVIC POWERS PAST SCHWARTZMAN

Djokovic produced another dominant display to dismantle Schwartzman 6-3 6-4 6-4 on Rod Laver Arena, where the world number two kept his title hopes alive.

While Schwartzman fought hard, it was another routine outing for Djokovic - who reached his 11th Australian Open quarter-final.

Djokovic was broken for the first time since the opening round but was never really in danger, hitting 38 winners and 31 unforced errors.

"Today was a good test because Diego was in form, he hasn't dropped a set in three rounds," the Serbian said afterwards.

"Obviously he can be a very dangerous opponent from the baseline if you give him time. I knew that. I stepped out on the court with a clear game plan what I need to do."

RAONIC TAKES DOWN CILIC

It rained aces as 32nd seed and former world number three Raonic beat former runner-up Cilic 6-4 6-3 7-5.

Raonic progressed to his fifth quarter-final in Melbourne after firing down 35 aces and winning all of his service games in two hours and 19 minutes.

His reward? A showdown with Serbian superstar Djokovic, who boasts a dominant 9-0 head-to-head record.

"I'm going to have to serve well clearly, and then I think I'm going to have to get my return at a high percentage, make him play a lot of those points, and then try to be efficient on my service games," Raonic said in his news conference.

"I think we play quite opposite from each other, and he's done a good job in the past neutralising my serve. So I have really got to focus on my things well and be the one dictating."

Roger Federer again recovered from a poor opening set to progress to the quarter-finals of the Australian Open on Sunday.

The 20-time grand slam champion lifted his game after a sluggish start to beat Marton Fucsovics 4-6 6-1 6-2 6-2 on Rod Laver Arena.

Federer battled back from the brink in round three to defeat John Millman in a final-set tie-break, and many were left wondering whether playing more than four hours and finishing at 0048 local time on Friday would take its toll.

He certainly seemed several steps off the pace in a lacklustre first set, but Federer duly responded to produce some of his best tennis of the tournament to claim his 101st Australian Open match win against the world number 67.

Federer will face Tennys Sandgren in the last eight, with a semi-final showdown against Novak Djokovic still on the horizon.

Too many wayward shots saw Federer give up the first set to Millman, and Sunday's match followed a similar pattern as Fucsovics threatened an upset.

The Hungarian appeared untroubled by the Federer backhand slice and looked comfortable when trading blows from the baseline before breaking in game seven after a series of errors from the Swiss.

With the crowd clearly left uneasy by his pedestrian start, Federer raced into control of the second set, holding to love and breaking for the first time when Fucsovics sent a forehand long.

Having survived a scare on serve, Federer moved 5-1 ahead after a useful net cord before serving out the set with more customary precision.

By now in full flow, Federer began the third with a showcase of his variety, a thumping winner and a sublime drop shot - both from the backhand - teeing up a break that Fucsovics handed to him with a foolhardy slice.

Two break points came and went for Fucsovics after a brilliant Federer forehand yielded the most emphatic fist-pump of the evening from the 38-year-old, whose movement across the court belied the marathon match he played just 48 hours earlier.

Fucsovics did move back to 4-2 after a loose game from Federer, but he mistakenly let a mishit lob land on the line to hand back another break, and the six-time champion closed out with a crisp volley.

With everything falling into place for Federer - he was even four from four on Hawk-Eye challenges - Fucsovics lost heart as a first double fault of the match and some overhit ground strokes left him 2-5 down.

Fucsovics had seemed troubled by the tension of his racket strings as the evening waned, but there was no such anxiety within the packed crowd, the roars a fitting way to end Australia Day as Fucsovics sent a forehand into the net on the third match point.

Ashleigh Barty avenged her fourth-round defeat at Wimbledon to Alison Riske by overcoming the American in three sets in the Australian Open fourth round.

The world number one battled to victory in an hour and 36 minutes to book a quarter-final meeting with Petra Kvitova, who came from a set down to beat Maria Sakkari.

Coco Gauff saw her brilliant week end in disappointment as she lost to compatriot Sofia Kenin, who is into the last eight of a grand slam singles tournament for the first time.

Qiang Wang, who stunned Serena Williams in round three, was defeated in straight sets by Ons Jabeur – another woman making major history in Melbourne.

NO REWARD FOR RISKE AS BARTY BATTLES ON 

Australia's hope for a home champion continues after Barty recovered from a miserable second set to defeat Riske for the first time. 

Riske won their first encounter in Eastbourne in 2016 before taking victory at Wimbledon last year, but Barty ended that losing streak with a 6-3 1-6 6-4 success. 

Barty was clinical in the opening set against too many errors from Riske, but the 29-year-old rallied in the second, breaking twice and dropping just five points on her own serve to force the decider. 

At 5-4, Barty set up match point with a backhand pass and Riske produced just her second double fault to hand victory to the favourite. 

"It was third time's a charm for me tonight," said Barty. "I just had to hang in there. It was very tough from both ends playing very differently. I just had to give myself a chance." 

Barty will face Kvitova next in a repeat of last year's quarter-final, the Czech having fought from a set down to defeat Sakkari.

"I love Petra, but let's hope she doesn't break my heart again on Tuesday!" said Barty, who was beaten 6-1 6-4 at Rod Laver Arena in 2019.

  

COCO MANIA DEPARTS MELBOURNE​, JABEUR MAKES HISTORY

Gauff's fairytale run came to an end at the hands of countrywoman Kenin, who steamrolled the 15-year-old 6-7 (5-7) 6-3 6-0 on Melbourne Arena.

American sensation Gauff dethroned defending champion Naomi Osaka in the previous round and she looked on track to reach the quarters in Melbourne.

However, fellow rising star and 14th seed Kenin blitzed Gauff to reach her first grand slam quarter-final.

Next up for Kenin is Jabeur after the Tunisian beat Chinese star Qiang Wang 7-6 (7-4) 6-1.

Wang eliminated 23-time slam singles champion Williams in the third round, however, she was unable to back it up on Sunday.

Jabeur, who hit 29 winners, became the first Arab woman to ever make a slam quarter-final.

KVITOVA RETURNS TO QUARTERS

Australian Open runner-up Kvitova avoided a major upset as she rallied past Sakkari 6-7 (4-7) 6-3 6-2 on Rod Laver Arena.

After losing a tight first set, two-time Wimbledon winner Kvitova hit 33 winners and broke Sakkari eight times en route to a fourth quarter-final in Melbourne.

Playing in front of a vocal Green contingent supporting Sakkari, Kvitova said: "When I was shaking the hand with the umpire, I told him it was like a soccer match today. I mean, it's nice on one side. On the other side, it's the tennis, and it's not a Fed Cup. It's strange. But it didn't bother me at all."

Coco Gauff said playing at the Olympic Games in Tokyo this year is "definitely the goal" following the 15-year-old's Australian Open exit.

Gauff's fairytale run in Melbourne came to an end at the hands of fellow American Sofia Kenin, who rallied past the teenage sensation 6-7 (5-7) 6-3 6-0 in the fourth round on Sunday.

After dethroning defending champion Naomi Osaka, highly rated Gauff was unable to get past Kenin to reach her maiden grand slam quarter-final.

But the world number 67 was in good spirits post-match as she looks to qualify for Tokyo 2020.

"That's definitely the goal," Gauff told reporters when asked about the Olympics, which gets underway in July. "Hopefully I can get my ranking up and qualify. I'm sure the cutoff is French Open. 

"I'm pretty sure I only have like three tournaments before French Open, so… it will be difficult. But I'm going to try as hard as possible. I definitely do want to play the Olympics. I mean, it would be pretty cool."

Gauff dazzled in her first Australian Open main draw appearance, upstaging Venus Williams, Sorana Cirstea and Osaka en route to the last 16.

"My short-term goal is to improve," Gauff added. "That's the main thing. I'm doing well right now at 15. I still have so much I feel like I can get better on. Even my parents, my team, they all believe I can get better.

"I don't even think this is close to a peak for me, even though I'm doing well right now. The goal is just really to get better, you know, have these good runs at tournaments, building up my experience and playing more tournaments just so I can be ready for matches like this today."
