Stefanos Tsitsipas battled through to the Miami Open round of 16 and he was joined by Andrey Rublev on Monday.

Greek star and second seed Tsitsipas got the better of 2014 US Open runner-up Kei Nishikori in Miami.

Rublev continued his fine 2021 with a straight-sets demolition of Marton Fucsovics at the ATP 1000 tournament.

In-form Aslan Karatsev, however, bowed out following a surprise loss to Sebastian Korda.

 

TSITSIPAS HALTS NISHIKORI

Despite a mid-match wobble, Tsitsipas overcame Nishikori 6-3 3-6 6-1 to reach the fourth round.

Former world number four Nishikori forced a deciding set but Tsitsipas withstood the Japanese's comeback.

Tsitsipas, who hit 32 winners, will meet Lorenzo Sonego for a place in the quarter-finals after the 24th seed defeated Daniel Elahi Galan 7-6 (8-6) 6-3.

 

RUBLEV STAYS HOT

Russian fourth seed Rublev made light work of Fucsovics 6-2 6-1 in just 52 minutes.

Rublev leads the ATP Tour with 18 victories this season after eliminating the in-form Hungarian, ahead of top seed Daniil Medvedev (16-2).

The result secured a third win for Rublev over 29th seed Fucsovics this month.

"I was laughing, because of [the] situation and plus Marton also told me, 'I don't want to see you. I don't want to see you'," Rublev said, cracking a laugh. "[It was] just a situation that [was] fun, and I feel sorry."

Awaiting Rublev is 2014 US Open champion and former world number three Marin Cilic, who beat Lorenzo Musetti 6-3 6-4.

 

KARATSEV CONQUERED

For only the third time this year, Australian Open semi-finalist and Dubai Tennis Championships winner Karatsev tasted defeat following a 6-3 6-0 loss at the hands of Korda.

American sensation Korda became the first player outside the top five to beat Karatsev this year, with the latter's previous two losses coming against world number one Novak Djokovic and world number four Dominic Thiem.

"It is super special [to reach the Round of 16], especially playing a guy who was as hot as he was," said Korda. "I just took the tactics that I used [against him] at Roland Garros and it worked out really well today."

Diego Schwartzman stands in the way of Korda and the quarters after the fifth seed accounted for Adrian Mannarino 6-1 6-4.

Elsewhere, Denis Shapovalov – the sixth seed – was upstaged by Hubert Hurkacz 6-3 7-6 (8-6).

Another Canadian awaits Hurkacz after 12th seed Milos Raonic was a 6-4 7-5 winner against Ugo Humbert.

Stefanos Tsitsipas continued his strong run of form en route to the Miami Open third round, while Aslan Karatsev's maintained his fairytale run in 2021.

Greek star Tsitsipas flexed his muscles in a straight-sets win over Damir Dzumhur on Saturday.

Australian Open semi-finalist and Dubai Tennis Championships winner Karatsev enjoyed a victorious Miami debut.

Andrey Rublev, Diego Schwartzman, Denis Shapovalov, Marin Cilic and Milos Raonic also progressed at the ATP 1000 tournament.

 

TSITSIPAS STAYS HOT

World number five Tsitsipas eased past Dzumhur 6-1 6-4 in his first appearance since losing in last week's Mexican Open final.

Tsitsipas (15-4) became the third player to reach 15 wins this season, the second seed following in the footsteps of Russian duo Rublev (17-3) and Daniil Medvedev (15-2).

"It was a great match, especially against a guy that I probably don't have a good record playing against in the past," said Tsitsipas. "I started the match very strong, breaking him twice and taking a big lead in the score, and I think the things worked out by themselves after that."

Tsitsipas will face Kei Nishikori after the Japanese outlasted Aljaz Bedene 7-6 (8-6) 5-7 6-4.

 

NO STOPPING KARATSEV

Karatsev's Miami Open debut ended in a 6-4 6-3 win for the 17th-seeded Russian over Mikhail Kukushkin.

Already in the ATP's top 100 and set to keep climbing, Karatsev broke serve four times en route to the next round, where Sebastian Korda awaits after upstaging 10th seed Fabio Fognini 1-6 6-4 6-2.

"Of course it gives me confidence to win my first title, but you arrive here and it’s a different surface and new tournament," said Karatsev, who ended last season ranked 112th before bursting into the top 30 behind his semi-final run at Melbourne Park. "So you try [to think of it] as a new tournament and new place, but of course it gives me a lot of confidence."

Karatsev owns a 13-2 record this year, with his only two losses coming against world number one Novak Djokovic and US Open champion Dominic Thiem.

 

RUBLEV ROLLS ON

Fourth seed Rublev has proven to be remarkably consistent, highlighted by his crushing 6-1 6-2 rain-interrupted victory against Tennys Sandgren.

Having equalled his previous best run in Miami, Rublev will play 29th seed Marton Fucsovics who took down Thanasi Kokkinakis 7-6 (7-3) 6-7 (4-7) 6-4.

Rublev has won a Tour-leading 17 matches this year.

Elsewhere, fifth seed Schwartzman was a 6-3 6-3 winner against Yasutaka Uchiyama, Shapovalov – the sixth seed – trumped Ilya Ivashka 6-7 (5-7) 6-4 6-4 in a marathon, 12th seed Raonic accounted for Jordan Thompson 6-2 6-1, former US Open winner Cilic surprised 13th seed Christian Garin 3-6 7-5 7-6 (7-5), while 15th seed Alex de Minaur was eliminated.

Top seed Stefanos Tsitsipas and fellow star Alexander Zverev progressed to the Mexican Open quarter-finals on Wednesday, but Milos Raonic bowed out.

Tsitsipas was too good for big-serving American John Isner in a 6-3 6-2 victory in Acapulco midweek.

A two-time Australian Open finalist, having also reached the French Open final four last year, Tsitsipas excelled on serve against Isner.

Greek star Tsitsipas only dropped one point on his first serve – not facing a break point throughout the last-16 contest – while firing down eight aces.

Standing in the way of Tsitsipas and a semi-final spot at the ATP 500 tournament is Canadian sensation Felix Auger-Aliassime.

In a battle of the NextGen, seventh seed Auger-Aliassime saved four of five break points in a 6-3 6-4 win over wild card Sebastian Korda.

Zverev will feature in his third Mexican Open quarter-final in four years after the second seed took down Laslo Djere 6-4 6-3.

Runner-up in 2019, Zverev will next face eighth seed Casper Ruud – who topped Tallon Griekspoor 4-6 6-3 7-6 (7-3) in the quarters.

"I think today what showed the most is that I got better with the match," Zverev said. "I started off extremely sloppy, started off with a lot of unforced errors.

"The longer the match went on the better I started playing and this is something that is very important for me. When I get into a rhythm I feel very comfortable on court and that's how I felt today."

Elsewhere, Lorenzo Musetti's giant-slaying run continued following a 2-6 6-3 7-6 (7-1) victory against Frances Tiafoe.

Musetti earned his first ATP 500 quarter-final as the Italian prepares to meet fifth seed Grigor Dimitrov, who eased past Miomir Kecmanovic 6-4 6-2.

There was an upset after fourth seed Raonic crashed out 6-4 6-2 at the hands of Dominik Koepfer, while sixth seed Fabio Fognini lost 6-4 6-3 against Cameron Norrie.

Italian qualifier Lorenzo Musetti may be ranked 120th in the world but he claimed his maiden top-10 scalp on Tuesday, beating Diego Schwartzman in the first round of the Mexican Open.

Musetti, the Australian Open boys' singles champion in 2019, secured a 6-3 2-6 6-4 win over ninth-ranked Schwartzman in a stunning success.

"There is a lot of work, a lot of sacrifice and I think some tears left in my eyes," the 19-year-old said during his on-court interview.

"I'm really proud of myself, but now I'm going to work harder and focus on the next days."

Musetti, whose forehand was excellent, defeated both Stan Wawrinka and Kei Nishikori at the Internazionali d'Italia in Rome last year.

Top seed Stefanos Tsitsipas had no such trouble, easing into the second round, where he will face big-serving American John Isner.

The Greek world number five beat France's Benoit Paire 6-3 6-1, aided by a strong display on serve.

"I didn't know what to expect from Benoit today," Tsitsipas said. "I think it's kind of tricky playing a tournament you haven't played before."

On facing 27th-ranked Isner next up, Tsitsipas added: "He's a guy that serves really well so that's going to be the biggest element and the one thing that I'll really have to resolve during that match."

Fourth seed Milos Raonic sent down 13 aces as he defeated American Tommy Paul 7-6 (8-6) 6-4.

In the late match, fifth seed Grigor Dimitrov got past Adrian Mannarino, who retired when trailing 6-4 3-0.

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

Djokovic is through to a 12th quarter-final in Melbourne, the eight-time winner last failing to reach the stage in 2018, when he lost to Hyeon Chung.

WINNERS/UNFORCED ERRORS
Djokovic – 41/25
Raonic – 50/35

ACES/DOUBLE FAULTS
Djokovic – 10/3
Raonic – 26/3

BREAK POINTS WON
Djokovic – 3/11
Raonic – 1/3

Novak Djokovic insists there is a real danger he may withdraw from the Australian Open, with an ultrasound on an abdominal injury planned for Saturday.

The eight-time champion at Melbourne Park pulled off a dramatic five-set win over American Taylor Fritz to reach round four, but it came at what could prove a high cost.

After battling through two tight sets to forge ahead in the match, Djokovic was jolted early in the third by a sudden "tear", as he put it.

Although painkillers allowed him to continue and fend off a Fritz comeback, the world number one might be advised by doctors that his race in Australia is run for this year.

He is due to face Milos Raonic on Sunday in round four, and the Canadian is a player that Djokovic holds an 11-0 winning career record against. This time Raonic could be gifted a walkover.

Explaining the injury blow, and what comes next, Djokovic said: "Everything was working fine for me, and then beginning of the third set I made this quick move on the return going to the forehand, rotating there, and I just felt a tear, I felt something happen.

"Went out for medical timeout when I was tested, evaluated. I have huge pain, I took the highest dose of anti-inflammatories possible.

"It did kick in end of fourth, beginning of the fifth when I actually started to move and I could actually start to rally with him from back of the court.

"Until that moment, it was only serve for me and kind of hoping and praying that I'm going to get an easy ball after my serve so I could just go for it. That's what I've done.

"I honestly don't know how I won this match. I'm very proud, at the same time sad and worried, because it's definitely something serious happening with my injury.

"I don't have much time to recover for the next match. Definitely not training tomorrow [Saturday]."

The 33-year-old Serbian would not want to risk worsening the problem, given he has plenty to play for over the rest of the year.

However, he is chasing grand slam success wherever he can get it, given he trails Roger Federer and Rafael Nadal by three on the all-time list.

Djokovic's disqualification for hitting a ball that struck a line judge at the US Open last year was followed by defeat to Nadal in the French Open final, and now his luck may be out again.

Once the tests take place on Saturday, there should be a greater sense of clarity in Djokovic's mind.

Setting the scene for what should have been a relaxed day of practice but is now a crucial day in his championship, Djokovic stressed he hoped to be able to continue.

He said of his Saturday plan: "I'm coming here to evaluate more with the doctor and medical team, and do some ultrasound and understand what's really going on so that the doctor and medical team can prescribe best possible treatment and the only possible treatment that I could even have the slightest chance to go out in less than 48 hours."

Novak Djokovic is unsure whether he will be able to play in the Australian Open fourth round after struggling with an abdominal injury in his five-set win over Taylor Fritz.

The world number one survived a huge injury scare to get past Fritz in the third round, winning 7-6 (7-1) 6-4 3-6 4-6 6-2 on Rod Laver Arena.

Eight-time Australian Open champion Djokovic appeared to injure his abdominal region during the third set.

It was a match which started on Friday in front of a crowd and finished on Saturday without fans as Victoria went into a five-day lockdown.

Fritz appeared set to reach the fourth round of a major for the first time in his career, but Djokovic suddenly came to life in the fifth set.

Next up for Djokovic is Milos Raonic, who he has beaten in all 11 of their meetings, on Sunday.

But the Serbian is concerned by his injury and was unable to commit to saying he would be able to take to the court.

"I really don't know," Djokovic said when asked for his thoughts about facing Raonic.

"Right now, I know it's a tear, definitely, of the muscle so I don't know if I'll manage to recover from that in less than two days.

"I don't know. I don't know. I don't know if I'm going to step out on the court or not.

"I am very proud of this achievement. Let's see what happens."

Djokovic felt for American Fritz after his brave defeat and discussed what he had gone through during a contest lasting three hours and 25 minutes.

He continued: "I want to congratulate Taylor for a great fight. I'm sorry that he lost the match obviously.

"I don't know. I just tried to stay in there and I was hopeful that whatever is happening there is going to feel better.

"Towards the end of the fourth it started to feel better, third and fourth set I just served and couldn't do much on the return.

"I was just going for my shots, was hitting two first serves and it worked, it worked well.

"This is definitely one of the more special wins in my life. It doesn't matter what round it is and against who it is.

"Under these kinds of circumstances, to pull this through is definitely something I'll remember forever."

The war of words between Novak Djokovic and Nick Kyrgios continued on day one of the Australian Open, while Gael Monfils was reduced to tears after a first-round exit.

Reigning champion Djokovic cruised past Jeremy Chardy 6-3 6-1 6-2 in just over an hour and a half but was unwilling to be drawn on comments made by Kyrgios following the home favourite's 6-4 6-4 6-4 success against Frederico Ferreira Silva.

Djokovic, who has now won 15 straight Australian Open matches, will take on Frances Tiafoe next and Kyrgios has a meeting with Ugo Humbert. A potential crossing of their paths on court could not happen until the semi-finals.

Monfils, seeded 10th at Melbourne Park, could not hide his emotions after succumbing to a 3-6 6-4 7-5 3-6 6-3 defeat in a five-set thriller against Emil Ruusuvuori.

Benoit Paire was the only other seed to go out on day one, with Dominic Thiem, Alexander Zverev, Diego Schwartzman and Stan Wawrinka picking up victories.

 

"HE'S A STRANGE CAT"

On the eve of the first grand slam of the year Djokovic said he had "no respect" for Kyrgios off the court, which the Australian was confused by as he pointed out the charitable work he has done during the coronavirus pandemic.

Kyrgios was previously critical of the Adria Tour organised by Djokovic last year, which ended with multiple players testing positive for COVID-19.

Asked about the Serbian's pre-tournament comment, Kyrgios said: "It actually would make complete sense to me if he was like, 'Look, I don't respect the guy on the court.' Because I understand if he doesn't agree with some of my antics on the court that I have done in the past.

"He's a very strange cat, Novak is. Heck of a tennis player, but unfortunately someone that's partying with his shirt off during a global pandemic, I don't know if I can take any slack from that man. That's as bad as it gets for me."

When a reporter asked if they could read those comments out to Djokovic in his post-match news conference, the 17-time major champion replied: "You can read it, but I'm not gonna answer to anything."

Upon hearing the remarks and being asked if he had a reply, Djokovic simply said: "No."

 

ANOTHER LOSS FOR MONFILS

Having lost his first-round match to Ruusuvuori, who incredibly saved 17 break points, Monfils remained without a win on the ATP Tour since February 2020.

The Frenchman was eliminated in the first round at Melbourne Park for the first time since 2006 and admitted he had lost all his self-belief and was finding it extremely difficult to get himself back on track.

"I don't have any confidence. I would like to get out of this nightmare but I can't," said Monfils.

"I don’t know when it's going to end. It's hard. Every time I get here I feel judged, I've lost again. I can't serve, I'm playing badly. I'm being honest and it's going to take time."

 

BEST OF THE REST

Thiem made light work of Mikhail Kukushkin 7-6 (7-2) 6-2 6-3 to set up a second-round meeting with Dominik Koepfer, but Zverev had to come from a set down to beat Marcos Giron 6-7 (8-10), 7-6 (7-5) 6-3 6-2. He will face Maxime Cressy next.

Denis Shapovalov also had to fight back to defeat Jannik Sinner, who reached the French Open quarter-finals last year, in an entertaining five-setter on Margaret Court Arena.

Marin Cilic, the runner-up at Melbourne Park in 2018, went down 6-4 6-2 7-6 (7-5) to Grigor Dimitrov, while Pablo Carreno Busta overcame Kei Nishikori 7-5 7-6 (7-4) 6-2.

There were straight-set wins for Stan Wawrinka, Milos Raonic and Felix Auger-Aliassime against Paulo Sousa, Federico Coria and Cedrik-Marcel Stebe respectively, and Schwartzman defeated Elias Ymer 7-6 (7-3) 6-4 2-6 6-2.

Rafael Nadal maintained his perfect record against Pablo Carreno Busta to reach the Paris Masters semi-finals and send Diego Schwartzman to the ATP Finals.

World number two Nadal is bidding to win the ATP Masters 1000 tournament for the first time and fought from a set down to triumph 4-6 7-5 6-1 and improve his record against his fellow Spaniard to 7-0.

With Schwartzman having lost his quarter-final against Daniil Medvedev 6-3 6-1 earlier on Friday, Carreno Busta needed to win back-to-back titles in Paris and Sofia to stop the Argentinian taking the last remaining qualifying spot for the season-ending tournament.

He appeared to have a significant chance of keeping his hopes alive when he engineered three break points at the start of the second set, but 20-time grand slam champion Nadal held firm and forced his way into a final-four meeting with Alexander Zverev or Stan Wawrinka.

Nadal came under early pressure on his serve and Carreno Busta took his second chance to break, his impressive groundstrokes proving difficult for his opponent to cope with.

Back-to-back brilliant backhands put him on the brink of going a set and a break up in the first game of the second, but Nadal dug in to hold and began to step through the gears.

Carreno Busta showed impressive resilience to keep the contest on serve in games two and eight, before a wicked forehand down the line forced the match to a decider.

The ninth seed was broken to love in game four of the decider and won just two more points as Nadal surged to victory.

In the other semi-final Medvedev will take on Milos Raonic after the Russian took just 63 minutes to dispatch of Schwartzman.

Things were not as easy for Raonic, who staved off two match points and sent down 25 aces as he overcame Ugo Humbert 6-3 3-6 7-6 (9-7).

The Canadian saved all three of the break points he faced in the third set – and five out of six overall – and closed out the victory with a final ace.

Diego Schwartzman eased to a straight-sets win over home hope Oscar Otte but there was a shock in store for Denis Shapovalov at the Cologne Championships.

Second seed Schwartzman, ranked ninth in the world, needed just 81 minutes to seal a 6-3 6-2 victory, setting up a third-round meeting with Alejandro Davidovich Fokina.

It was a less happy outing for third seed Shapovalov in Germany, the Canadian succumbing to a 6-1 4-6 6-2 loss against Gilles Simon.

The result represented a measure of revenge for Simon after the Frenchman lost to world number 12 Shapovalov in the first round of the French Open.

"I am really happy with the way I played, with the focus I had over all of the match," Simon said in his on-court interview. 

"I am really happy to beat him, because it is a very, very good win. I had a tough match with him at Roland Garros. I lost it unfortunately, so I am happy that I am the winner this time."

Jannik Sinner awaits for Simon after he defeated Pierre-Hugues Herbert, while Yoshihito Nishioka also made it through.

At the European Open in Antwerp, top seed and home favourite David Goffin suffered a stunning 6-3 7-5 defeat to American qualifier Marcos Giron.

Giron's surprise victory put him in the last eight of a ATP Tour event for the first time and he saved 10 of 13 break points he faced for a maiden victory over a top-20 opponent.

Milos Raonic was not to be denied a place in the quarter-finals, though, and a 7-5 7-6 (7-4) defeat of Cameron Norrie means he will now meet Grigor Dimitrov.

Alexander Zverev started his quest to win back-to-back ATP tournaments in Cologne with a battling victory over John Millman.

Zverev was crowned Cologne Indoors champion last weekend and the US Open runner-up moved into the quarter-finals of the Cologne Championships on Wednesday.

The top seed beat Australian Millman 6-0 3-6 6-3, despite double-faulting 10 times, and has now won 11 of his last 12 matches on hard courts.

Zverev saved six of the seven break points Millman earned and won 79 per cent of points behind his first serve, setting up a last-eight meeting with eighth seed Adrian Mannarino.

Mannarino was a 6-3 6-3 winner against Miomir Kecmanovic, while Alejandro Davidovich Fokina advanced to the quarter-finals following a 7-6 (7-3) 6-3 victory over Steve Johnson.

Felix Auger-Aliassime, beaten by Zverev in the final on Sunday, rallied past qualifier Egor Gerasimov 4-6 7-6 (7-2) 7-6 (7-4).

Pablo Carreno Busta slumped to a surprise defeat at the European Open in Antwerp, Ugo Humbert beating the second seed 5-7 6-3 6-4.

Frenchman Humbert was joined in the quarter-finals by Grigor Dimitrov, Alex De Minaur and Dan Evans, while Milos Raonic and Taylor Fritz progressed to the round of 16.

ATP Finals hopefuls Andrey Rublev and Denis Shapovalov will meet in the semi-finals of the St Petersburg Open after claiming straight-sets victories on Friday. 

Rublev holds the final automatic qualification spot for the season-ending tournament in London next month following a 6-2 6-1 win over Cameron Norrie. 

The third seed was a cut above Brit Norrie, improving his record to 32 victories and just seven defeats this year, which has included three titles. 

Shapovalov, meanwhile, beat Stan Wawrinka 6-4 7-5 in a battle between youth and experience, the 21-year-old Canadian winning 84 per cent of his first-service points. 

Milos Raonic defeated fellow seed Karen Khachanov 6-1 7-6 (7-1) and will face Borna Coric in the other semi-final, the Croatian having ousted Reilly Opelka in straight sets.

Top seed Alexander Zverev moved into the last four of the Cologne Indoors on home soil, beating South African qualifier Lloyd Harris 6-4 3-6 6-0. 

Zverev will come up against Alejandro Davidovich Fokina in his third semi-final of the year after the unseeded Spaniard got past Dennis Novak 6-3 2-6 6-3. 

Roberto Bautista Agut and Felix Auger-Aliassime will do battle for a place in the final following wins over Hubert Hurkacz and Radu Albot respectively. 

Marco Cecchinato and Lorenzo Musetti will be hoping to contest an all-Italian Sardegna Open in their homeland after advancing to the last four on Friday, along with Serbian duo Laslo Djere and Danilo Petrovic.

 

Andy Murray suffered another disappointing defeat as he lost to Fernando Verdasco in the first round of the Cologne Indoors tournament.

A 6-4 6-4 loss came against a player he once led 13-1 in their career head-to-head, a gap which has now closed to 13-4 after a hat-trick of wins for Spanish left-hander Verdasco.

Following victories for Verdasco at the US Open and Shenzhen Open in 2018, the Madrid man again got the better of the two-time Wimbledon champion, beating the Scot on an indoor hard court for the first time after five previous defeats.

It was a tough draw for Murray, who also struck unlucky at the French Open last month when he was paired with former champion Stan Wawrinka in the first round and also lost in straight sets.

The former world number one had entered the Cologne event, a low-level ATP 250 tournament, in the hope of building up match practice and registering the wins he needs to improve his ranking, which stands at 115 after his battle with injury in recent seasons.

Marin Cilic and Gilles Simon won through to the second round earlier in the day at the German event.

At the St Petersburg Open, Belarusian qualifier Ilya Ivashka survived an on-court meltdown to beat French player Adrian Mannarino 6-3 7-6 (8-6) in the first round.

Trailing 3-2 in the second set, Ivashka insisted on taking a toilet break and was penalised a game on his return to court, for delaying the match.

Ivashka explained to the chair umpire he had asked for a medical timeout because he "wasn't able to stand on court", only to be told such a break could not be used for a toilet trip.

The red mist descended as a seething Ivashka shouted: "That is not possible. It is not possible."

The punishment meant the 26-year-old fell 4-2 behind in the set, but he managed to turn around the situation to progress to the last-16 stage, where Denis Shapovalov or Viktor Troicki will await.

At the same tournament, Russian Andrey Rublev began his first week as a top-10 player by scoring a comfortable 6-2 6-4 win over Canadian Vasek Pospisil.

Milos Raonic, who skipped the French Open where Rublev reached the quarter-finals, fired 21 aces in a 7-6 (7-5) 6-1 win against JJ Wolf.

In Italy, home player Lorenzo Sonego followed up his run to the fourth round of the French Open with a 6-2 7-6 (7-4) opening win over 18-year-old compatriot Giulio Zeppieri at the Sardegna Open.

Dusan Lajovic set up a meeting with Rafael Nadal as a host of seeds and big names fell by the wayside at the Internazionali d'Italia on Thursday.

Neither Novak Djokovic nor Nadal was in action after scoring victories a day earlier, but there was no shortage of shocks.

Home hopeful and seventh seed Fabio Fognini was among those to lose, going down 7-5 7-6 (7-4) to Ugo Humbert.

The match saw a remarkable 11 breaks of serve, including the first six games of the opener before Fognini was broken to love, then losing an early advantage in the second-set tie-break.

He was joined in making an early exit by US Open quarter-finalist Andrey Rublev.

Beaten by brilliant Russian compatriot Daniil Medvedev in the last eight at Flushing Meadows, Rublev lost in three sets to Hubert Hurkacz on this occasion.

Fifth seed Gael Monfils succumbed 6-2 6-4 to qualifier Dominik Koepfer, while Milos Raonic fell to Lajovic as the Serbian secured the Nadal clash, landing a 7-6 (7-3) 4-6 6-2 success.

Kei Nishikori also tumbled out as he struggles to regain his rhythm on the ATP Tour.

The former world number four was appearing in just his second tournament of the year due to an elbow injury and then the coronavirus pandemic but could not get past Lorenzo Musetti.

Musetti, an 18-year-old qualifier, had already dumped out Stan Wawrinka and said after his 6-3 6-4 success: "I think I played really smart. It was different to Wawrinka.

"They are great champions and I am really happy right now."

He was the only Italian man to win, though, with Casper Ruud seeing off Lorenzo Sonego.

Denis Shapovalov had a straightforward victory and Diego Schwartzman also headed through in two sets.
