Rafael Nadal reached the Australian Open quarter-finals for the 13th time in his career with a straight-sets win over Fabio Fognini.
The Spanish star again looked in strong form in a 6-3 6-4 6-2 victory over Italian 16th seed Fognini behind closed doors on Rod Laver Arena on Monday.
Nadal, who is aiming to win a men's record 21st grand slam title in Melbourne, is yet to drop a set at the year's first major and beat Fognini for the 13th time in 17 meetings.
The world number two will face either Stefanos Tsitsipas or Matteo Berrettini in the last eight.
Nadal gave up an early break lead against Fognini but a powerful forehand return led to another and a 4-2 lead.
Despite serving at just 42 per cent, Nadal closed out the opening set.
Fognini was unable to consolidate a break lead in the second set, having led 4-2, before Nadal recovered from 0-40 down to hold in the eighth game.
That would prove a decisive hold, Fognini blasting a ball into the stands after netting a volley to give Nadal a break point, converted when a forehand went wide before the Spaniard secured the set.
Fognini handed Nadal his only loss from two-sets-to-love up at a grand slam at the US Open in 2015, but a break for 2-1 in the third saw the latter end any chances of a repeat on his way to a convincing win.
Data Slam: Nadal's fine Australian Open record
Only at the French Open, where he is a 13-time champion, has Nadal reached the quarter-finals more often (14) than at the Australian Open. Roger Federer (15) and John Newcombe (14) are the only men to have reached more Australian Open quarter-finals.

Brooklyn Nets star Kevin Durant will miss at least two games due to a mild left hamstring strain.
The Nets confirmed the injury on Sunday, a day after Durant returned from the NBA's health and safety protocols amid the coronavirus pandemic to help Brooklyn past the Golden State Warriors 134-117.
Durant, who posted 20 points against former team the Warriors in his first game back in the Bay Area, will sit out Monday's clash with the Sacramento Kings and Tuesday's game against the Phoenix Suns.
Former NBA MVP and two-time champion Durant is averaging 29.0 points, 7.3 rebounds and 5.3 assists per game for the Nets this season.
Durant, who sat out his first season in Brooklyn due to an Achilles injury sustained in the 2019 NBA Finals during his time with the Warriors, has missed nine of 28 games in 2020-21.
The star-studded Nets (16-12) are third in the Eastern Conference following back-to-back wins.
The Denver Nuggets ended the Los Angeles Lakers' winning streak in the NBA, while the Milwaukee Bucks slipped to another loss.
Inspired by a Nikola Jokic triple-double of 23 points, 16 rebounds and 10 assists, the Nuggets snapped the Lakers' seven-game winning streak with a 122-105 victory on Sunday.
Jamal Murray had a game-high 25 points for the Nuggets (15-11).
LeBron James managed 22 points, 10 rebounds and nine assists for the Lakers, who saw Anthony Davis (15 points in 14 minutes) suffer an Achilles strain.
The Bucks' losing run continued with a 114-109 defeat to the Oklahoma City Thunder.
Giannis Antetokounmpo finished with a triple-double of 24 points, 17 rebounds and 10 assists, but the Bucks were beaten.
Antetokounmpo has 100 points, 43 rebounds and 21 assists over the past three games, yet Milwaukee have lost all three.
He joined Russell Westbrook (November 2016) as the only players in the past 30 years to have 100-40-20 over a three-game span but lose all three.
Lillard lifts Trail Blazers, Towns shines
Damian Lillard scored 34 points and had 11 assists to see the Portland Trail Blazers end the Dallas Mavericks' four-game winning streak with a 121-118 success.
Luka Doncic led the Mavs with 44 points and nine assists, but he missed a jump shot that would have brough Dallas level with five seconds remaining.
Karl-Anthony Towns' double-double of 20 points and 11 rebounds helped the Minnesota Timberwolves overcome the Toronto Raptors 116-112.
The Washington Wizards upset the Boston Celtics 104-91 on the back of 35 points from Bradley Beal.
Lou Williams posted 30 points and 10 assists in the Los Angeles Clippers' 128-111 win over the Cleveland Cavaliers.
Celtics' slump continues
The loss marked Boston's 10th in their past 15 games. Star Jayson Tatum in particular struggled, going three-of-14 from the field for six points in 23 minutes.
Dynamic Doncic
Doncic hit an incredible three-pointer in the Mavericks' loss. He was five-of-eight from three-point range.

76ers at Jazz
The teams leading their respective conferences meet on Monday. The Utah Jazz (22-5) are on a seven-game winning streak ahead of hosting the Philadelphia 76ers (18-9).
Serena Williams is moving better than she has in years, according to her coach Patrick Mouratoglou.
Williams, 39, has looked in good form at the Australian Open as she eyes a record-equalling 24th grand slam singles title.
The American has dropped just one set on her way to the quarter-finals, in which she faces Simona Halep on Tuesday.
Mouratoglou said Williams' movement was the best it has been in several years.
"First of all, it's something that we have put the emphasis on because in tennis that's probably one of the most important things. If you are late on the ball, you can't do what you want to do. Sometimes you don't even touch the ball," he told a news conference on Monday.
"It's a sport where you have to be able to move fast from side to side and long enough. It's something that probably in the last two, three years, this had consequences for Serena.
"Even more, when you're not in a good day, you need a plan B. To be able to have a plan B, you have to be able to move well. If you can't move well, there is no plan B. The only plan is attack.
"I think it cost her a few important matches. So we have decided to find a way to bring back the footwork that she used to have in the past. I feel like she's done a great job. She's moving much better."
Williams last won a major title in Melbourne in 2017, losing four grand slam finals since then.
With all eyes on her as she aims to equal Margaret Court's record of 24 grand slam singles titles, Mouratoglou insisted that mark was not an obsession for Williams.
"Does she need that validation? I don't think she needs that validation. But, I mean, clearly she came back to tennis to win some other grand slams, so that's for sure the goal," he said.
"Now, she's not as obsessed with the 24 than most of the people in the tennis world, but definitely she wants to win grand slams. That's the only reason why she came back to tennis."
Kemba Walker is confident the Boston Celtics will overcome their form slump after falling to another loss on Sunday.
The Celtics suffered their 10th loss in their past 15 games with a 104-91 defeat to the Washington Wizards.
Walker, who posted 25 points in the loss, was upbeat about the Celtics' chances of turning their season around.
"We've got to change some things, and we will. We will," Walker said.
"I'm very confident that we will change things and we will continue to get better. It'll change because it's not a great feeling the way we're playing. It can't get no worse than this. We're going to fix it."
Jaylen Brown also posted 25 points, but Jayson Tatum struggled, going three-of-14 from the field for just six points in 23 minutes.
Walker said the Celtics, who are now 13-13, would work together, with their next outing coming against the Denver Nuggets on Tuesday.
"Teams go through adversity every single year at some point in the season," he said.
"It's all about how you overcome it. The only way you can overcome adversity is by doing it as a whole, doing it together. And that we will do."
Andy Farrell said Ireland are "hurting" physically and mentally after they suffered a 15-13 Six Nations defeat to France at the Aviva Stadium on Sunday.
Les Bleus ended a 10-year wait for a win in Dublin, digging deep to make it two wins out of two and consign the men in green to back-to-back defeats at the start of a Six Nations campaign for the first time.
France were clinical and defended brilliantly, with Charles Ollivon scoring a classy first-half try against the run of play and Damian Penaud crossing after the break.
Ronan Kelleher's first Test try after 57 minutes left a gripping battle in the balance and Ross Byrne's mammoth long-range penalty set up a tense finale, but France held on to leave Ireland's title hopes all-but over.
Ireland were already without Johnny Sexton, Conor Murray and James Ryan due to injury and their luck at the start of the tournament was summed up when Iain Henderson and Cian Healy had to go off with blood streaming from their heads after a collision.
Both players were able to return but they were unable to prevent another defeat in a game of fine margins, with James Lowe's first-half try ruled out by the TMO as his foot made contact with the touchline.
Ireland head coach Farrell said: "I thought we managed the game really well in the first half – even though the rain stopped it was still very wet, and obviously the French like to come with a lot of line speed.
"They defended really well in those last two minutes there. I thought the plan was going according to plan and we were doing very well set-piece wise, and our game management was very good. I thought we just lost our way a little bit in the third quarter there, and that got them back into the game.
"I suppose, really, when you look at it, if you give them set-pieces in your own half, they get over the gain line first phase, come round the corner second phase and get into their offloading game, then they're free-flowing. Some of that was a little bit soft from us.
"A lot of lads that are hurting in there – physically hurting as well as mentally. Because they put their bodies on the line for their country. The effort's not the problem at all, but it still hurts to lose this game."
Jamaican Olympian Alia Atkinson continued her winning ways at the multi-site Southern Zone Sectionals that got underway in Coral Springs and Sarasota respectively late last week.
In the 50m butterfly at Coral Springs, Atkinson was in a league of her own as she stopped the clock in 26.61. Second overall went to Olivia Peoples of the Bolles Sharks in Sarasota and Kathryn Giuffdra of Haines City Tritons in Coral Springs who both clocked 27.73.
The time was the Atkinson was under 27 seconds since 2018. It is also her third fastest ever performance and puts her national record of 26.54 in jeopardy.
In the 50m breaststroke Atkinson easily won gold in a time of 31.45.
Second place went to Marcela Scaramuzza of Trinity Prep in 33.10 and Taylor Grabenhorst won bronze in 33.15.
In winning, Atkinson easily demolished her 2021 season-best of 33.47 set last Saturday at Plantation. With her win on Thursday, the national record holder extends her unbeaten streak in the event in America to eight races.
Since 2017, she has turned back all challengers on US soil. She is the only CARIFTA region swimmer to make the World Championship final in the event. She also holds the accolade of being the only medalist in this sprint race.
Meanwhile, national teammate Morgan Cogle, who represents the Jupiter Dragons, lowered her personal best of 33.33 from 2018 in the 50m backstroke crushing it to record 32.67 and place 18th overall.
World Championship representative Keanan Dols who swims for the Gator Swim Club was 21st in the 50-metre butterfly stopping the clock in a time of 26.63.
Huge roars echoed around the Aviva Stadium as the ball sailed into an empty stand to end France's 10-year wait for a win in Ireland.
Time and again Les Bleus have suffered the agony of defeat in Dublin, but they showed a combination of style and substance to make it two Six Nations victories out of two.
Booming bellows of celebration and relief could be heard loud and clear on a wet Sunday as France held on to win an almighty battle 15-13.
Les Bleus have not won a Six Nations title for 11 years, consistently proving to be great entertainers but falling short with defensive fragility, indiscipline and a lack of clear thinking.
This is a different France in the Fabien Galthie era, though, with defence coach Shaun Edwards having worked wonders in a relatively short space of time to make them such a tough nut to crack.
Englishman Edwards has given France a strong backbone and that was essential as they frustrated a wounded Ireland, who were missing captain Johnny Sexton, James Ryan and Conor Murray due to injury.
A try in each half from inspirational captain Charles Ollivon and Damian Penaud proved to be decisive, with France providing the cutting edge that Ireland lacked.
Ireland had 59 per cent possession but were only able to break through a brick wall of a French defensive once, when Ronan Kelleher nipped in to set up a tense finale.
France made 180 tackles to 122 from Ireland, who will head into a rest weekend with two defeats from two, while their conquerors lead the way with Wales on nine points after making a big statement.
Billy Burns made a confident start as he set about trying to make up for his costly last-gasp kick in the loss to Wales and although he was off target with a poor first penalty, the fly-half made no mistake soon after to put Ireland in front.
The men in green were dominant and had an extra man when Bernard Le Roux was sin-binned 23 minutes in for tripping Keith Earls.
France were under the pump but stood firm, the excellent Brice Dulin grabbing slippery high balls as Ireland continued to knock at the door, missing out on an opening try when the TMO spotted James Lowe's foot touched the line as he was tackled in the corner.
Les Bleus were relishing the battle and showed their class with ball in hand to hit the front in style after 28 minutes.
The mercurial Antoine Dupont and Matthieu Jalibert featuring in a showreel of offloads before Gael Fickou tossed a clever pass over Jamison Gibson-Park, setting up captain Ollivon for a brilliant score.
Jalibert booted France into a 10-3 lead at the break and Ireland's luck was out again when Cian Healy and stand-in captain Iain Henderson went off with blood pouring from their heads following an unfortunate collision.
Penaud extended France's lead with another clinical try following a strong carry from the powerful Fickou and a fine Jalibert pass, but Kelleher scooped a loose ball from a lineout to score his first Ireland try with 56 minutes on the clock.
The nerves were jangling when Jalibert hit a post from the tee and a mammoth Ross Byrne penalty reduced the deficit to two points with 16 minutes to play.
Yet France defended for their lives to get the job done, showing fight and finesse to avoid more Dublin doom and gloom.
Ireland's Six Nations hopes are in tatters after they fell to a second successive defeat, a comeback attempt falling short in a 15-13 loss to France.
Andy Farrell's side were undone by an early red card for Peter O'Mahony against Wales, but it was their failure to capitalise in the 10 minutes when France were down to 14 that proved key this time around.
Charles Ollivon scored the first of two France tries while they were undermanned, giving the visitors an advantage they never surrendered.
They led 15-3 five minutes before the hour and, although a spirited revival gave Ireland hope, the hosts could not complete a turnaround, meaning their championship prospects are effectively over. France, by contrast, go into the first rest weekend top of the table.
Matthieu Jalibert and Billy Burns each missed early penalties before Burns knocked a simple one over to give Ireland a 3-0 lead.
The hosts were then boosted further when Bernard Le Roux was shown a yellow card for tripping during a kick-chase.
James Lowe looked to have taken an immediate advantage when he went over in the left corner but the TMO ruled he had been pushed into touch by the scrambling France defence.
Ireland were punished for not taking that chance in stunning fashion as a wonderful France attack, in which the ball was intricately worked to the right and then back left, ended with Gael Fickou sending Ollivon over.
Jallibert added the extras and landed a penalty shortly before the interval.
France wasted a golden opportunity to go further ahead following a superb carry from Julien Marchand before Ireland's task was made more difficult when Cian Healy and Iain Henderson clashed heads in a tackle.
Ed Byrne and Ultan Dillane entered the fray as replacements for their bloodied team-mates but could not help Ireland wrest control of the game away from France.
The visitors' command was strengthened in the 57th minute when Jallibert looped a long pass out to Brice Dulin, who shrugged off a defender and fed Damian Penaud for France's second try.
Yet Jallibert failed with the conversion and, after Ollivon was penalised from the kick-off, Ronan Kelleher marked his introduction by strolling over following a fortunate bounce at a line-out.
A long-range penalty from Ross Byrne trimmed the gap to two points and Jallibert failed to respond in kind nine minutes from time as he struck the upright from 51 metres.
But as in Cardiff last week, Ireland failed to produce a dramatic final say and will likely be playing for little more than pride for the rest of the tournament.
Novak Djokovic fought into the quarter-finals of the Australian Open despite concerns over a muscle injury, seeing off Milos Raonic in four sets.
Djokovic's hopes of defending his title appeared to be in doubt when he said he had a "muscle tear" and was unsure whether he would play the fourth-round clash.
But his history of dominance over Raonic was perhaps a motivating factor in him taking to the court and he stretched his head to head lead to 12-0 with his 300th grand slam win, becoming only the second player in history to reach the landmark.
He did not have it all his own way, a spirited Raonic levelling matters in the second set after losing the first on a tie-break.
However, Djokovic was in control thereafter, progressing 7-6 (7-4) 4-6 6-1 6-4, though a last-eight meeting with Alexander Zverev may prove a sterner test.
Djokovic made it eight wins in nine in tie-breaks with Raonic to take the first set and things looked bleak for the Canadian when he received treatment on his foot in the second set.
But that break proved just the tonic for Raonic as he went on to win a set against Djokovic for the first time in four grand slam meetings.
Yet the tide turned emphatically back in Djokovic's favour in the third – the Serbian winning five straight games to move into a 2-1 lead.
His success came through a familiar strategy against a player of Raonic's power on serve.
Djokovic wasted few opportunities to punish the second serve and consistently took Raonic out of his comfort zone by forcing him into long rallies.
Raonic, to his credit, did save four break points in the fourth set but the dam finally burst and he could not prevent Djokovic from snatching the fifth chance that came his way, the world number one ensuring there was to be no shock as he reached another milestone in a remarkable career.
Data Slam: Djokovic's delightful dozen

Simona Halep set up a quarter-final duel with Serena Williams after showing admirable character to battle back from a set down to beat Iga Swiatek 3-6 6-1 6-4 and seal her 100th grand slam match win.
Halep and Swiatek put on a thrilling show in the night session on Sunday, as the Romanian two-time grand slam champion demonstrated her fighting spirit to come from a set down and reach the last eight.
Swiatek took charge in the first set after saving the first two break points of the contest, eventually putting herself in a commanding position as she won the 10 of the final 11 points of the set, but Halep remained focused as her 19-year-old opponent began to wobble in the second.
Halep then snuffed out any threat of a turnaround by breaking back straight after losing on her own service in the decider and she went on to set up a meeting with Williams, who had overpowered Aryna Sabalenka earlier in the day.
Naomi Osaka also advanced, though she was by no means comfortable, while Hsieh Su-wei beat Marketa Vondrousova in straight sets.
HALEP'S REVENGE
Halep's clash with Swiatek was their first since the French Open last October, when Swiatek ran out a 6-1 6-2 winner and went on to claim her maiden major title.
Revenge was on the cards at Melbourne Park and Halep got the job done impressively, showing her mettle to return from a set down.
"Well, I thought before the match that I have to be a little bit more aggressive than Paris. In Paris I have been very far back, and my ball didn't go through the court," the second seed said. "So, I thought that it's a better chance to go and hit.
"The pressure came from the way I played the last match against her. I just expected a better game from myself, which I did, and I'm really happy about that."
Halep accepts facing Williams will be an entirely different challenge, but she remains confident despite lauding the American a "legend" in her on-court interview.
"Of course it's different, she's the only one with 23 grand slams, so you cannot compare Serena with all of us, because we do not have so many grand slams," Halep added.
"But when I step on the court, it's just another opponent, and always I'm focused on myself more than I focus on who I play. We played so many times. I know what to expect. I will just try to do my game, and I will be confident."
WILLIAMS ON COURSE
All eyes are on Williams yet again, as she hopes to equal Margaret Court's record of 24 grand slam titles – and on the evidence of her latest win, she will take some stopping as she won 6-4 2-6 6-4.
Williams revealed she had to cope with a little off-court stress this week with her clothing line, and Sabalenka certainly kept the pressure up as the 22-year-old took the second set.
But Williams responded well to the seventh seed, who became the first player to take a set off the former world number one. Williams said she remained confident despite that setback.
"Like I said on the court, I just felt like even games that I lost, I was so close to winning. Not all games, but probably most of those games," she said. "I just needed to play better on the big points. I knew that I could. I still hadn't reached my peak. I was like, 'Okay, Serena, you got this, just keep going.'"
OSAKA RELEASES HER ANGER
Osaka was in a real spot of bother against Garbine Muguruza, but saved two match points.
The 2019 champion Osaka steadied herself and felt more composed after a brief show of frustration, as she struck the ground with her racquet.
Ultimately, she emerged a 4-6 6-4 7-5 victor, and Osaka felt letting frustration get the better of her for a moment helped her cause.
"On the first match point, I was just thinking that I didn't hit a decent serve that entire game, so I should really focus on my serve," he said. "I feel like my serve stats were pretty good that set, so I was just telling myself to do better.
"Then on the second point, when the rally started, I just told myself not to push [the ball] but also don't do something crazy and make a really bad unforced error. I felt the entire match I was overthinking. There was a moment when I got angry and hit my racquet on the ground. I feel like I released a lot of the thoughts that I had. It just made me go more into instinct-based tennis."
She will face Hsieh next, the world number 71 having beaten Vondrousova – ranked 51 places higher – 6-4 6-2.
Kevin Durant was grateful for the warm reception and tribute video upon his first return to the Golden State Warriors as he led the Brooklyn Nets to a 134-117 win on Saturday.
Durant spent three seasons with the Warriors, winning two NBA Championships and was named Finals MVP twice.
He was absent last season after undergoing surgery on a torn Achilles tendon in Game 5 of the 2019 NBA Finals, and then opted to leave as a free agent in July that year.
Saturday's contest was his first return to face the Warriors after sitting out 2019-20, and he went on to play an important role with 20 points, second only to Kyrie Irving (23) on the Nets' side.
Durant was impressed with the focus the Nets displayed, but he went on to revel in the tribute and reception afforded to him by his former team.
"We came out and played a great game," Durant said afterwards. "We were focused from this morning in shootaround, and it was a good vibe all day.
"The tribute video was cool. I think about those moments daily. Every single moment that I have had in this league, I think about it and try to analyse it and get better.
"My time here in Golden State was so much fun. It was such a big learning experience, especially learning basketball in a different philosophy. I'm going take to that with me for the rest of my life."
Warriors coach Steve Kerr was in charge throughout Durant's three-year spell in the Bay Area and felt the tribute video was the least they could do, and a similar acknowledgement will take place once fans are allowed back in attendance.
"This is something that is such a no-brainer," Kerr said. "When Kevin came here and gave us three years of just incredible basketball, the least we could do is welcome him back with open arms.
"He's a guy that gave everything to us for three years then left with a devastating injury. There should be a lot of love, he did so much for us.''
Victory leaves the Nets third in the Eastern Conference.
Serena Williams calmed injured fears after coming through a thrilling back-and-forth against Arnya Sabalenka to reach the quarter-finals of the Australian Open.
Williams, who is pursuing a record-equalling 24th career grand slam and her first major victory in four years, prevailed 6-4 2-6 6-4 after more than two hours on court against seventh seed Sabalenka.
Her struggles during the second set appeared partly attributable to a fall but Williams recovered her poise and the 39-year-old does not expect any ill-effects in a last-eight showdown against either Simona Halep or Iga Swiatek.
"I don't think so. It didn't hurt at all. I didn't roll my ankle, so that was good," she told reporters.
"Yeah, I think it was just dramatic, me being dramatic.
"My first thought was, 'Not another ankle sprain in Australia'. But I knew immediately that it wasn't.
"Then I was more embarrassed than anything. I was like, 'Oh, my goodness'."
Williams moved well throughout the contest, assuaging any lingering concerns over Achilles problems that have dogged her of late - even manging to rally when Sabalenka reeled off three consecutive games from 1-4 down in the decider.
"I've worked really hard on my movement. Yeah, I like retrieving balls. I mean, obviously I like to be on the offense, but I can play defence really well, as well.
"I do get a lot of balls back when I need to. I didn't think about my Achilles. It's so good to not think about it. Oh, my goodness. It's been a problem actually since 2018.
"I just never want that problem again. It feels really good to just play and to run, to not feel that. It's a great relief."
Arguably Williams' greatest inconvenience around the match was not a physical one, after she had to participate in a Saturday conference call to avert an "emergency" at her clothing business.
"Tennis is a lot less stressful. I don't have to manage a team. I do manage a team actually, but it's different," she chuckled. "Even though I am the CEO of my tennis team, it's definitely different.
"I think a part of me loves being on the court because it's free-flowing. It's not like I have to kind of just manage and make sure everyone is able to perform.
"I have a second career and it's fun. One of our main players, our employees, had an emergency. You got to step it up when you got to step it up.
"I was smart about that. I scheduled a call directly after my practice. I was like, 'Okay, I can do it early and still have the rest of the day to relax'.
"And it was during [Williams' daughter] Olympia's nap, so it was perfect."
Dominic Thiem's bid to reach back-to-back Australian Open finals was dashed by Grigor Dimitrov as the US Open champion surprisingly crashed out in the round of 16.
Thiem lost a thrilling final to Novak Djokovic in last year's Melbourne Park decider before breaking through for his maiden grand slam title at Flushing Meadows later in 2020.
But Thiem failed to secure another second-week berth in Melbourne, where the third seed was stunned 6-4 6-4 6-0 by former world number three Dimitrov on Sunday.
Thiem was aiming to reach the Australian Open quarter-finals for the second time and become the second Austrian man to feature in the quarters in Melbourne on multiple occasions after Thomas Muster (1989, 1994 and 1997).
The 27-year-old Thiem was also bidding to reach his ninth slam quarter-final and equal Muster's record for most major last-eight appearances by any Austrian – male or female.
However, Thiem – who rallied from two-sets-to-love down to top Nick Kyrgios in the previous round – was no match for Dimitrov behind closed doors on Rod Laver Arena amid a coronavirus lockdown in Victoria.
Both players hit 25 winners, but Dimitrov only tallied 18 unforced errors to Thiem's 41 following just over two hours on court.
Dimitrov progressed to his fourth Australian Open quarter-final, extending his record for most last-eight appearances at Melbourne Park by a Bulgarian player – man or woman.
An Australian Open semi-finalist in 2017, Dimitrov will now contest his sixth grand slam quarter-final – the 29-year-old is third for most quarter-final appearances by a Bulgarian player, behind Manuela Maleeva (nine) and Katerina Maleeva (seven).
Wayne Pivac urged Wales not to get carried away with making it two wins from two in this year's Six Nations by beating Scotland 25-24 at Murrayfield on Saturday.
Darcy Graham and Stuart Hogg put Scotland 14 points ahead in the first half, only for Louis Rees-Zammit to reduce the deficit before half-time.
Liam Williams and Wyn Jones touched down either side of a red card for Zander Fagerson to put Wales in front for the first time, before Hogg went over again for the depleted hosts.
However, Rees-Zammit scored a brilliant solo try to seal a bonus-point victory, which followed a win over 14-man Ireland on the opening weekend of the tournament.
Prior to this year's Six Nations, Wales had won just three of Pivac's first 10 Tests at the helm and he urged them to remain grounded despite the upturn in results.
"From 17-3 down against a side full a confidence, it was very, very pleasing," said Pivac.
"There were some big moments from both sides so we are just happy to come away with a win.
"We are improving each week in certain areas of the game and we showed a lot of character today.
"The squad has changed a lot since autumn, and it's tournament rugby now, a couple months is a long time to reflect.
"We cannot get carried away with this, though, and we need to build on it."
Having also set up Williams' try, Rees-Zammit has been directly involved in six tries in just five starts for Wales (four scored, two assisted).
Pivac said of the Gloucester wing: "Louis Rees-Zammit is doing some very good things with the ball. He's got things to work on, he dropped a high ball earlier and he wasn't the complete package, but he has scored some really well-worked tries."
Hogg took his Test try tally to 22, with Ian Smith and Tony Stanger (both 24) the only players to have registered more for Scotland.
He was frustrated Gregor Townsend's men let the game slip through their fingers a week after a famous victory over reigning champions England at Twickenham.
"We're bitterly disappointed. For large parts of that game we were very much in control of it. We looked the dominant side, especially in the first half, and we started to be ill-disciplined," he told the BBC.
"For us, giving away a couple of penalties is fine, four on the bounce is unacceptable. We've gone from one end of the field to the other conceding seven points within a couple of minutes and that's international rugby. You can't let a team like Wales get easy, cheap field positions because they are going to punish you.
"I think, for us, it's a vital lesson to stay disciplined throughout. It hurts right now, and rightly so."
Louis Rees-Zammit's excellent second try gave Wales a narrow 25-24 bonus-point victory over 14-man Scotland in the Six Nations.
After claiming a first win at Twickenham in 38 years by beating England 11-6 on the opening weekend, Scotland stormed ahead with tries from Darcy Graham and Stuart Hogg on Saturday.
Rees-Zammit went over before half-time and set up Liam Williams to haul Wales back into the game, and they took the lead when Wyn Jones touched down after Zander Fagerson saw red.
Hogg put Scotland back in front despite their numerical disadvantage but a stunning solo effort from Rees-Zammit saw Wales follow up their win over 14-man Ireland last week with another success.
Scotland only conceded six penalties against England but had half that amount inside six minutes, with Leigh Halfpenny splitting the posts after the third.
Finn Russell restored parity and added the extras after Ali Price chipped the ball over the Wales defence for Darcy Graham to dot down in the 18th minute.
The hosts increased their advantage when Halfpenny spilled Hogg's kick over the top and the Scotland full-back took it over the line, but Rees-Zammit reduced the arrears before half-time.
Halfpenny sat out the second half due to a failed HIA and, after Gary Graham had a try ruled out for obstruction, Williams went over in the left corner.
Scotland were reduced to 14 men when Fagerson was dismissed for catching Jones on the head at the breakdown, and the Wales prop made them pay by scoring a third try.
The hosts responded with a sustained spell of pressure in front of the posts that culminated in Hogg evading Owen Watkin and Nick Tompkins to cross.
However, Rees-Zammit showed incredible pace to chase down his own kick and score the decisive points with 10 minutes remaining.
England are back to being themselves after recovering from last week's defeat to Scotland with a 41-18 victory over Italy on Saturday, according to captain Owen Farrell.
The reigning champions ran in six tries to claim a bonus-point victory at Twickenham, a week on from losing 11-6 to Calcutta Cup rivals Scotland.
Monty Ioane put Italy ahead early on but Jonny Hill gave England lift-off with their opening try and Anthony Watson crossed over either side of Jonny May's 32nd Test try.
Jack Willis touched down on his debut and, though Tommaso Allan added a second for Italy, it was plain sailing for the home side as Elliot Daly ran through down the left.
And while accepting England were far from their best against Italy, Farrell was pleased with the way they responded to their opening loss.
"We're back to being 'us' there," he told ITV. "It wasn't a perfect performance, not the best we've ever had, but in terms of the feeling, the energy and the intent, that felt back to 'us'..
"We had some honest conversations with ourselves during the week... there was excitement to get on the training field and put things right.
"And the way that we built up showed in the way that we played. I thought we attacked the game.
"Obviously they had an advantage to move the ball and they ended up scoring a try, which was probably a bit over over-eagerness from us
"But after that I thought our intent was brilliant. We got in behind them, probably not everything went our way, but we stuck at it and the game ended up going our way."
England have now won each of their 22 Six Nations fixtures against Italy, who have lost their last 29 matches in the competition in a run stretching back to February 2015.
The Azzurri offered promising glimpses, not least with their second-quickest ever Six Nations try through Ioane, but England ultimately proved too strong on home soil.
"Credit to Italy, they were tough, they never gave up, and we knew they were going to do that," said England prop Kyle Sinckler.
"Up front they were strong, their forwards carried hard, their backs had good energy... it was a tough, tough test match but our boys got stuck in there and got the win."
Echoing the thoughts of skipper Farrell, Sinckler hailed England's response to last week's rare home loss.
"I think it was a step in right direction. I think our intent was a lot better today, especially up front," he said.
"We probably didn't get the rewards we wanted, but in terms of the intent, and showing how much it means to us to play for our country, I think it was a step in the right direction.
"We were obviously very frustrated with the performance last week, and we knew we had to step up and play the England way, and the way we want to dominate up front.
"We did that at times today, but we know there's so much more to give. But like I said, it was a step in the right direction. The game's done, we move on to the next one."
Next up for England is a showdown with Wales at the Principality Stadium on February 27.
Rafael Nadal was able to offer a positive update on his fitness after easing into the second week at the Australian Open.
The 20-time grand slam champion is playing in his first tournament since November's ATP Finals and faced a battle to make the Melbourne major due to a back problem.
But Nadal has made the fourth round without dropping a set, seeing off Cameron Norrie 7-5 6-2 7-5 on Saturday.
"I did things well, [then there are] things that I need to improve. Something normal," the Spaniard said. "But, yes, happy, of course. Second week, straight sets. Can't complain."
PAIN RELIEF AT LAST FOR RAFA
Nadal might have been similarly dominant in his prior matches but revealed after beating Norrie he is only now feeling fitter.
"No, the back was not getting better each day; it was getting better today," he said. "But today is better, yeah, the first day I feel an improvement, and that's the most important thing for me today, more than any other thing.
"Of course, I was not serving my normal serve for the last 15 days. Today is the first day that I started to serve again my normal serve.
"But yesterday I didn't practice, so today was just warming up with the new, normal movement.
"So, of course, I didn't serve bad, but I can do better, I think. And I'm looking forward to doing it better. It has been an important victory for me.
"The biggest victory is the back is better for the first day. That's the most important thing."
Nadal will face Fabio Fognini next after he ended Australia's interest in the home grand slam with a 6-4 6-3 6-4 victory over Alex De Minaur, the host nation's final hope.
"It's one of those matches," an impressed De Minaur said. "You're out there leaving it all out there, but you can just feel that he's playing at another level."
MOODY MEDVEDEV MAKES AMENDS
There are three Russian men in the last 16 for the first time in Melbourne in the Open Era, but the country's biggest name survived a major scare.
Daniil Medvedev was cruising after taking the first two sets against Filip Krajinovic, only to drop the next two and engage in an angry back-and-forth with coach Gilles Cervara.
Cervara eventually left Medvedev's box as the fourth seed trailed 4-1 in the fourth set and did not return, but the 25-year-old recovered to get the job done in dominant fashion, a 6-3 6-3 4-6 3-6 6-0 victor.
Medvedev, with Mackenzie McDonald next, said of the incident with Cervara: "He said just before leaving that he's sure I'm going to win the match, but he's going to leave to let me be more calm.
"Sometimes maybe I will disagree but this time for sure it was a good thing to do.
"Today it helped, and definitely we're going to talk about it a little bit, but there is not a big deal."
Andrey Rublev joined Medvedev and compatriot Aslan Karatsev in the fourth round as he improved to 7-0 for the year with a three-set defeat of Feliciano Lopez. He will play Casper Ruud.
HISTORY CHANNEL OVER CHAMP
Defending champion Novak Djokovic's struggles with injury on Friday might have intrigued much of the tennis public, but Stefanos Tsitsipas was not overly concerned.
The fifth seed, who breezed past Mikael Ymer, did not watch the match and revealed he has little interest in keeping up with the exploits of his rivals.
"I might watch [Djokovic and Nadal] a little bit on TV if it happens that the TV is on or the right channel is on," he said. "Otherwise I just switch to History Channel.
"Definitely not tennis history. I think I have enough of tennis being in here every single day."
Tsitsipas will next play Matteo Berrettini, who is enjoying his best run at the Australian Open and saw off a side complaint to advance in three sets by edging Karen Khachanov, another Russian, in a trio of tie-breakers.
Ash Barty may have her focus on winning the Australian Open right now but suggested a career change could be on the cards in the future.
The world number one made sure she will still be competing during the second week of the tournament in Melbourne by beating Ekaterina Alexandrova in straight sets.
But, having played international cricket for Australia before switching to tennis, could the multi-talented Barty be considering trying another sport?
Elsewhere in Saturday's action, Karolina Pliskova lost her cool – and also a couple of rackets – as she slipped to defeat against the impressive Karolina Muchova in an empty Rod Laver Arena, with fans not able to be present due to a five-day lockdown in the state of Victoria.
Elina Svitolina had no such problems in her third-round match, while Elise Mertens was victorious in just over an hour against Belinda Bencic. Jennifer Brady ended Slovenian qualifier Kaja Juvan's run in the first grand slam of the year.
AUSSIE RULES, OK?
After winning 6-2 6-4 without ever needing to be at her peak, Barty was cheekily asked by former doubles partner Casey Dellacqua – now working in the media – whether she may be set to switch paths again, once her tennis career has come to an end.
Australian rules football was the answer – but Dellacqua maybe got more than she bargained for from her former playing partner during the on-court interview.
"I thought it was our deal, we're going to AFLW. It's ABCD [the nickname for the pairing from their doubles career]. We come as a package, and I know we will be going to the [Richmond] Tigers that is for sure," Barty said. "You can't go to Carlton. You have to come to the 'Tiges' with me."
Dellacqua replied: "I need to get out there and start practicing some kicking, but you are good. I would love to do that one day."
For Barty, though, the next challenge facing her is Shelby Rogers, who knocked out 21st seed Anett Kontaveit during the evening session.
MAKING A RACKET
A disgruntled Pliskova was not impressed when punished for smashing up a racket during her match with compatriot Muchova.
Having received a warning when throwing a racket to the floor during the course of the final game in the opening set, the sixth seed then vented her frustration again on another while in the players' tunnel.
An official witnessed the incident and reported it to chair umpire Alison Hughes, who punished the Czech with a point penalty before she began serving to open the second set.
"It's off court, I'm allowed to do what I want," Pliskova insisted when querying the decision to the official. She would go on to hold before recording two successive breaks, yet somehow failed to force a decider.
Muchova rallied from 5-0 down in sensational fashion, winning seven games on the spin to triumph 7-5 7-5 to make it through to the last 16.
CONTRASTING PROGRESS FOR SEEDS
Svitolina has still yet to drop a set in the tournament after overcoming 26th seed Yulia Putintseva by a 6-4 6-0 scoreline.
The fifth seed was twice down a break in the first set but, after eventually coming out on top to take a 1-0 lead, breezed through the second in a hurry.
"She has a very different game style from what I played my last two rounds, so it wasn't easy at the beginning to adjust," Svitolina said. "As soon as I was feeling better, I just stepped my game, and it was quite a comfortable win after."
Next up will be Jessica Pegula, who is through to the fourth round at a slam for the first time in her career after thrashing Kristina Mladenovic 6-2 6-1.
There was also success for another American in the main draw, Brady defeating Juvan in straight sets. Her reward is a clash with Donna Vekic, the 28th seed having to save a match point before eventually seeing off Kaia Kanepi 5-7 7-6 (7-2) 6-4 after two hours and 38 minutes on court.
