Novak Djokovic was "not really in the mood to speak" after suffering a jarring early defeat at the Monte Carlo Masters, but insisted he would bounce back.

The 35-year-old world number one was playing his 50th main-draw match at the tournament, but it did not go to plan as he lost 4-6 7-5 6-4 to Italian Lorenzo Musetti on Thursday.

Djokovic's post-match reaction exposed huge frustration, with his first competitive outing in over a month ending at the last-16 stage.

He was forced to miss the Indian Wells and Miami tournaments last month, being denied permission to enter the United States due to his refusal to accept a COVID-19 vaccination.

Hopes he had of a long run on the Monte Carlo clay have been scuppered, but the Serbian has plenty of time to find form in time for the French Open, which begins on May 28.

Defeat marked the first time Djokovic had failed to reach the quarter-finals in a tournament since last year's Monte Carlo event, when he lost his opening match to Alejandro Davidovich Fokina.

The loss to Musetti included an argument with the umpire over a line call, while Djokovic also smashed a racket in frustration at one point.

"The feeling is terrible after playing like this, honestly," Djokovic said. "But congrats to him. He stayed tough in important moments, and that's it.

"You always hope for the good day in the office, but I know I'm not playing so great and he's playing very well, so I knew it was going to be a tough match.

"I don't think it's catastrophic, but my feeling is bad right now because I lost the match. It's not a great day for me, so I'm not really in the mood to speak."

Djokovic is a two-time former winner of the ATP 1000 event but has not reached the semi-final stage since 2015, the year he was last champion.

He continues his clay campaign at a low level tournament next week in Banja Luka, Bosnia and Herzegovina.

Musetti moved on to face fellow Italian Jannik Sinner in the quarter-finals. Victory over Djokovic made Musetti the first Italian man to beat the world number one in Monte Carlo since 1973, when the ATP rankings began.

Rafael Nadal has confirmed he will not be competing at the Monte Carlo Masters.

Nadal, who has won 11 times in Monte Carlo, had been hoping to make his return from a hip injury at the ATP Masters 1000 event, which starts next week.

The 36-year-old has not played since going out to Mackenzie McDonald in the second round of the Australian Open in January.

Nadal previously cast doubt on his status for Monte Carlo last month, and on Tuesday he announced he will be unable to participate.

"Hi everyone, I'm still not ready to compete at the highest level," Nadal tweeted.

"I will not be able to play in one of the most important tournaments of my career, Monte Carlo.

"I am not yet in a position to play with the maximum guarantees and I continue my preparation process, hoping to return soon."

Nadal's latest setback is another blow in his preparations for the French Open, which starts at the end of May.

The Spaniard, who dominated in Monte Carlo between 2005 and 2012, has slipped down to number 14 in the ATP world rankings.

Daniil Medvedev won his fourth title of the 2023 season but claimed Sunday's Miami Open was the biggest one yet after knocking over Jannik Sinner 7-5 6-3 in the decider.

Medvedev improved his outstanding season record to 29-3, well ahead of the next best Sinner (21-5) with the straight-sets triumph. The Russian will rise to number four in the ATP world rankings on Monday.

The Miami title comes after the 27-year-old lifted crowns in Dubai, Doha and Rotterdam and reached the Indian Wells Open final, only to lose to top-ranked Carlos Alcaraz. During that run, Medvedev has an overall record of 24-1.

Despite Medvedev's remarkable form, Miami was his first ATP Masters 1000 title since winning the Canadian Open in Toronto in 2021.

"I haven't won such a big title in probably a year and a half," Medvedev said. "At the end I was quite shaky. Not even tight, because I'm not scared to win. But still the hands get a little shaky so the serve is a little bit tougher… I managed to get myself together and close the match.

"It's the best start of the season I have ever had. Amazing amount of points won. I think 2019 was great also with six finals and it was also new for me in 2019. So I think it's kind of the same." 

Medvedev triumphed in one hour and 34 minutes, although the contest was closer than the scoreline suggested, with both players hitting 27 winners and 14 unforced errors each.

The Russian was impressive on serve, winning 86 per cent of first serve points, but he also committed six double faults with nine aces.

"I'm really happy," Medvedev said. "Today was a tough match. It was probably the hottest day and the most humid during the day.

"It was not easy conditions. I don't know if Jannik had a small injury or cramp. I was also struggling, tried not to show it."

Medvedev is the first male to reach consecutive ATP 1000 finals since Novak Djokovic in 2020. The Russian's other ATP 1000 titles include Paris in 2020, Shanghai in 2019 and Cincinnati in 2019.

The 2021 US Open winner has also claimed 16 ATP tournament titles on hard courts since 2019, ahead of Djokovic (14) and Andrey Rublev (10) during that period. The ATP Tour now moves to clay courts.

"Generally I love hard courts," he said. "I love playing on it. If it would be my choice, it would be only hard courts, but I completely understand that that's not fair, if we can say like this. I feel the best at my game on hard courts."

Daniil Medvedev extended his perfect record against Jannik Sinner to six matches after defeating him 7-5 6-3 in Sunday's Miami Open final.

Medvedev also beat Sinner in February's Rotterdam Open final, marking his fifth win from their fifth meeting, and by improving that to 6-0 it means it is the Russian's equal-best record against a single opponent, along with Felix Auger-Aliassime and Diego Schwartzman.

Sinner had a great opportunity to take the first set, creating five break point opportunities compared to Medvedev's three, and he kept his service games clean with no double faults while Medvedev racked up four.

The 21-year-old Italian could have forced a tiebreaker in the first set, but failed to hold his serve at 6-5 down, and Medvedev capitalised on the momentum to grab an immediate break to start the second frame.

To Sinner's credit, he snatched the break right back, but Medvedev got another and safely served it out the rest of the way.

The writing was on the wall after the first set, as Medvedev came into the contest a perfect 24-0 this season when securing the opener, and the title is his 16th on hard courts since 2019, two more than second-placed Novak Djokovic (14) over the span.

It is his 19th singles title overall – at a 19th different tournament – and after a brief rough patch getting over the line, he has become one of the sport's great finishers. 

From November 2021 through June 2022 he lost five finals in a row, but he has since won six of his past seven, claiming his fifth Masters 1000 crown in the process.

Jannik Sinner is through to the Miami Open decider after eliminating world number one Carlos Alcaraz 6-7 (4-7) 6-4 6-2 in Friday's semi-final.

Sinner, 21, has enjoyed a terrific start to 2023. Since the beginning of the Australian Open, the Italian has only lost three matches – to Stefanos Tsitsipas, Daniil Medvedev and Alcaraz.

He avenged his defeat to Tsitsipas with a straight sets win at the Rotterdam Open, and he has now got one back on Alcaraz after their three-hour war of attrition.

Both players created exactly 12 break point opportunities, and Sinner's 26 unforced errors were only one less than Alcaraz's 27, but the Spanish 19-year-old committed an uncharacteristic nine double faults. The loss snapped Alcaraz's 10-match winning streak.

The victory gives Sinner his second appearance in the Miami Open final after losing the 2021 edition to Hubert Hurkacz, and he now joins Rafael Nadal and Novak Djokovic as the only players to ever reach the final here twice before turning 22.

Sinner will get a chance to avenge his only other loss this year in the final after Daniil Medvedev booked his spot with a 7-6 (7-5) 3-6 6-3 victory over Russian compatriot Karen Khachanov.

Incredibly, Khachanov lost despite hitting 53 winners and only 11 unforced errors, and he ended up edging the total point count 93-88, but he could only convert two of his six break point opportunities, while Medvedev converted two out of four.

The win means Medvedev is the first player since Roger Federer in 2019 to reach the final of both the Indian Wells Open and the Miami Open in the same season, and he is the first since Federer in 2006 to reach five ATP finals before the clay court season begins.

World number one Carlos Alcaraz made it 10 wins in a row in Miami and kept alive his hopes of a rare Sunshine Double as he beat Taylor Fritz in straight sets in Thursday's quarter-finals.

Alcaraz swept aside the 2022 Indian Wells champion 6-4 6-2 in a lopsided Miami Open contest which lasted only 79 minutes, with the Spaniard breaking Fritz in the opening game of both sets.

Both players hit 20 winners, including 11 each on their respective forehands, but Fritz almost doubled Alcaraz' unforced errors count (28-13).

The 19-year-old was impressive from the baseline and overwhelmed Fritz in the end. The American only won 38 per cent on his second serve.

Alcaraz, who won the Indian Wells title a fortnight ago, remains on track to become the eighth male to win the Sunshine Double (Indian Wells and Miami), with Roger Federer the last to achieve that in 2017.

The Spaniard would join Federer (2005, 2006, 2017), Novak Djokovic (2011, 2014, 2015, 2016), Andre Agassi (2001), Marcelo Rios (1998), Pete Sampras (1994), Michael Chang (1992) and Jim Courier (1991) in achieving the Sunshine Double.

Alcaraz will take on Italian 10th seed Jannik Sinner in the semi-finals, after the duo faced off in the Indian Wells last four a fortnight ago, with the Spaniard winning in straight sets.

In-form Daniil Medvedev progressed to the semi-finals with a 6-3 7-5 victory over American qualifier Chrstopher Eubanks, who had enjoyed a dream run in Miami.

Medvedev has a 27-3 record this season and will pursue a fifth straight ATP Tour final when he takes on compatriot Karen Khachanov in the semi-finals.

Khachanov, who made this year's Australian Open semi-finals, defeated Francisco Cerundolo 6-3 6-2 in 76 minutes.

Italian 10th seed Jannik Sinner downed Emil Ruusuvuori to secure his berth in the Miami Open semi-finals along with bringing up his 20th win of the season on Wednesday.

Sinner, who dropped only one point on first serve, won 6-3 6-1 over the Finn in one hour and 16 minutes.

The 21-year-old Italian will face either top seed and defending champion Carlos Alcaraz or 2022 Indian Wells winner Taylor Fritz in the last four. Sinner lost to Alcaraz in the Indian Wells semi-finals a fortnight ago.

Alcaraz and Fritz's Miami quarter-final was postponed to Thursday with persistent rain forcing the evening session in Miami to be cancelled.

The other quarter-finals between 14th seed Karen Khachanov and 25th seed Francisco Cerundolo along with fourth seed Daniil Medvedev and qualifier Christophr Eubanks were also re-scheduled for Thursday.

The Sinner-Ruusuvuori clash was also impacted by a two-hour rain delay, but the Italian prevailed to maintain his perfect record in Miami, having not dropped a set.

"We both played well today but I won the important points," Sinner said. "It's never easy when you are up and you get interrupted, but I came back and played well."

Sinner's run to the Miami semi-finals has seen him drop the fewest games (23) since Rafael Nadal (21) and Novak Djokovic (23) in 2014.

The Italian became the seventh male to reach the semi-finals at both Indian Wells and Miami in a single year before turning 22, joining an elite list in Andre Agassi (1990), Jim Courier (1991), Djokovic (2007), Andy Murray (2007 and 2009), Nadal (2008) and Alcaraz (2022).

Sinner's 2023 record is now 20-4, bettered only by Medvedev (26-3) and Cameron Norrie (21-5).

Carlos Alcaraz does not disagree with Novak Djokovic's assertion of being the best player in the world, as the Spaniard outlined his hope of facing the 22-time major winner at full fitness.

Alcaraz has played Djokovic once before, overcoming the Serbian en route to triumphing at last year's Madrid Open.

The teenager's success in Madrid marked his fifth tour-level title, and his second at an ATP 1000 event.

Earlier in March, Alcaraz claimed his third ATP 1000 title with victory at the Indian Wells Open, seeing the 19-year-old leapfrog Djokovic – who has been unable to compete in the United States due to his COVID-19 vaccination status – back to the top of the world rankings.

Djokovic claimed in interview with The National in February that he was still the best player in the world when at 100 per cent fitness.

Alcaraz, for his part, shares that view.

"Well, it is tough one, but, I have to play against Novak when he's at 100 per cent," Alcaraz told reporters after beating Tommy Paul at the Miami Open, where he is defending champion.

"I would say in Madrid he played really, really well. So it was close. But I agree with him. When he's 100 per cent, probably the best player in the world.

"What Novak has achieved, the level of Novak for example in Australia was unbelievable, really high.

"So as I said before, I really want to play against Novak when he's 100 per cent and I'm sure I'm going to enjoy it. That's all I can say right now."

Alcaraz remains on course for the Sunshine Double – winning both the Indian Wells Open and Miami Open in the same season.

"I try not to think about that but it's difficult," he said. "You know, it's something that I really want. I want to be part of the few players that won the Sunshine Double.

"So for me, would be great to achieve that, but it's something that I try not think about and try to think about day by day, match by match, and that's all. 

"But of course it could be great to be part of that group of few players."

Eleven players, including Djokovic – on four occasions – have won the Sunshine Double, with WTA number one Iga Swiatek the latest to achieve the feat last season.

Second seed Stefanos Tsitsipas was bundled out of the Miami Open in straight sets during Tuesday's fourth round by 2022 US Open semi-finalist Karen Khachanov.

The Russian 14th seed prevailed 7-6 (7-4) 6-4 over Tsitsipas in one hour and 34 minutes, powering 25 winners and making only nine unforced errors, compared to the Greek's 14.

Khachanov's triumph ended a winless 0-6 head-to-head record against Tsitsipas, while it also snapped his own 23-match losing streak against top-10 opponents.

The Russian, who also made this year's Australian Open semi-finals, has qualified for four of his six tour-level events this year.

Khachanov will take on 25th seed Francisco Cerundolo in the quarter-finals, with the Argentinian fighting back to get past Lorenzo Sonego 3-6 6-3 6-2 in just over two hours.

Defending champion and top seed Carlos Alcaraz had less trouble against Tommy Paul, cruising into the quarter-finals with a 6-4 6-4 victory.

Alcaraz won the winners' count 24-9, setting up a quarter-final clash with ninth seed Taylor Fritz, as the Spanish 19-year-old chases a rare Sunshine Double, having won last week's Indian Wells Open.

Fritz progressed after getting past seventh seed Holger Rune 6-3 6-4 in 86 minutes, sending down eight aces and 22 winners for the match.

Fourth seed Daniil Medvedev played late into the evening after a lengthy rain delay in Miami, but made light work of Quinten Halys 6-4 6-2, triumphing just past 1:30am local time.

Medvedev, who is into his third straight Miami quarter-final, will face American qualifier Christopher Eubanks in the last eight after he got past Frenchman Adrian Mannarino 7-6 (7-2) 7-6 (7-5) in another rain-delayed contest.

Italian 10th seed Jannik Sinner knocked off sixth seed Andrey Rublev 6-2 6-4, advancing to face Emil Ruusuvuori after he beat Botic van de Zandschulp 4-6 6-4 7-5.

Rafael Nadal has cast doubt on a possible return at next month's Monte Carlo Masters after revealing he is still unsure when he will be ready to make his comeback.

The 22-time grand slam champion has been struggling with a left hip issue that contributed to his second-round exit at the Australian Open in January.

Nadal pulled out of hard-court contests at the Indian Wells Open and Miami Open as he continued to recover from the problem.

Speaking two weeks ago, Monte Carlo Masters director David Massey said Nadal was the first player to register for this year's Masters 1000 event, which begins on April 8.

The tournament's official Twitter account more recently suggested Nadal will "definitely" take part.

However, Nadal – who has slipped out of the world's top 10 men's tennis rankings for the first time in almost 18 years – denied that is the case.

"I don't know who gets this information," he is quoted as saying by Spanish publication Marca.

"Obviously if it were true, I would confirm it, but unfortunately I can't. I'm following my course and I don't know when I'll play again, that's the truth.

"I'm in a phase of increasing work. If I knew when I was going to return, I would say so, but I don't know.

"I can't confirm that I will play in Monte Carlo. Things are seen day by day. I prefer to say things when I really know them."

The Monte Carlo Masters kicks off the clay-court season ahead of events in Madrid and Rome, with the French Open – Nadal's favourite event – now just two months away.

Nadal has won the Monte Carlo Masters a record 11 times, though his most recent triumph came in 2018 with victory over Kei Nishikori in the final. 

Three of the top seeds in the Miami Open field were eliminated on Monday as Felix Auger-Aliassime, Hubert Hurkacz and Frances Tiafoe were all sent packing.

Fifth seed Auger-Aliassime was taken out 6-2 7-5 in one of the biggest wins of Francisco Cerundolo's career, with the Argentine avenging recent losses to the Canadian at both the Australian Open and the Indian Wells Open.

Adrian Mannarino's 7-6 (7-5) 7-6 (7-0) victory over eighth seed Hurkacz was arguably an even bigger upset, as it snapped his streak of nine consecutive losses against top-10 opponents at Masters 1000 events.

The 34-year-old Frenchman absorbed 20 aces from Hurkacz and still came out on top, limiting his own unforced errors to 13 for the match.

A third upset of the day saw unseeded Italian Lorenzo Sonego play a near faultless match to eliminate 12th seed Tiafoe, finishing the contest with 22 winners and only two unforced errors, while not facing a single break point in the brief 68-minute battle.

There was no drama for Daniil Medvedev as the fourth seed received a walkover against Alex Molcan, and he will face France's Quentin Halys in the fourth round after his 7-6 (7-2) 6-3 triumph over Mackenzie McDonald.

Two seed Stefanos Tsitsipas almost joined the long list of seeded victims, but he prevailed 6-3 4-6 6-4 against Christian Garin in the day's only three-setter.

The Greek star will meet Russian 14th seed Karen Khachanov in the fourth round after his comfortable 6-2 6-4 result over Jiri Lehecka, while unseeded American Christopher Eubanks finished the day's play with a 6-3 7-6 (9-7) defeat of Gregoire Barrere.

World number one Carlos Alcaraz wasted no time in advancing to the Miami Open third round with a straight-sets win over Facundo Bagnis in just 64 minutes, while 13th seed Alexander Zverev suffered an early exit on Friday.

Reigning US Open champion Alcaraz eased past Bagnis 6-0 6-2, firing 12 winners and three aces for the match, committing only 11 unforced errors.

The Spaniard won the first set in 24 minutes, marking the first time he has won an opening frame 6-0 at an ATP Masters 100 event. It was also the first bagel he has dished out since beating Bagnis in Umag last year.

"I knew that I needed to be focused for my first match," Alcaraz said after his win, having triumphed in Indian Wells last week. "To start a new tournament is never easy, different conditions.

"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning, and I'm happy with the way that I played. I try to improve every day."

Alcaraz will face Dusan Lajovic after he beat 30th seed Maxime Cressy 6-4 7-6 (7-2), having knocked off Andy Murray in the first round.

Zverev was the highest seed to bow out on Friday, going down 6-0 6-4 to Japan's Taro Daniel, who beat world number four Casper Ruud last month in Acapulco.

Daniel triumphed in 73 minutes against the German, hitting 17 winners and committing only two unforced errors for the match, while Zverev gave up 18.

The Japanese wild card will meet Emil Ruusuvuori in the third round after the Finn beat 22nd seed Roberto Bautista Agut 6-4 7-6 (7-5) to open up that section of the draw.

Third seed Ruud also had few problems getting past Ilya Ivashka 6-2 6-3 to set up a clash with Botic van de Zandschulp after his three-set win over Alexei Popyrin.

Sixth seed Andrey Rublev overcame J.J. Wolf 7-6 (7-3) 6-4, having been broken in the opening game of what was a tight contest.

Jannik Sinner beat Laslo Djere 6-4 6-2, marking his 16th win out of 20 appearances at the Sunshine Double (Indian Wells and Miami), with only three other players – Novak Djokovic, Alcaraz and Hubert Hurkacz – having as many wins within their first 20 matches.

Ninth seed Taylor Fritz defeated fellow American Emilio Nava 6-4 6-1, and will face Denis Shapovalov in round three after he beat Guido Pella 6-3 3-6 6-3.

American 16th seed Tommy Paul came from a set down to beat Marc-Andrea Huesler 5-7 6-3 6-4, while seventh seed Holger Rune beat Martin Fucsovics 6-3 7-5.

Richard Gasquet will get a showcase match against second-seed Stefanos Tsitsipas in the second round of the Miami Open after prevailing 6-4 3-6 6-1 against Christopher O'Connell on Thursday.

The biggest names in the field learned their opponents after the 32 seeded entrant received byes into the second round of the Masters 1000 event, and Tsitsipas will be desperate to avoid a third consecutive loss after quick exits at the Rotterdam Open and Indian Wells Open in recent weeks.

Fourth seed Daniil Medvedev is waiting for Roberto Carbellas Baena after he blew away Bernabe Zapata Miralles 6-0 3-0 (retired) in an all-Spanish showdown, while fifth seed Felix Auger-Aliassime will meet Brazil's Thiago Monteiro in the second round after his 6-4 7-6 (8-6) triumph over Australia's Jason Kubler.

After O'Connell and Kubler both fell, Thanasi Kokkinakis flew the flag for Australia with a 4-6 6-3 7-6 (9-7) comeback against Belgian wildcard Zizou Bergs, and his reward will be a battle against Polish eighth seed Hubert Hurkacz.

France's Gregoire Barrere earned a big matchup against 11th seed Cameron Norrie after eliminating Roman Safiullin 6-4 3-6 6-3, and Safiullin's Russian compatriot Pavel Kotov will join him on an early flight home after going down 6-2 6-2 against recent Chile Open finalist Tomas Martin Etcheverry.

Andy Murray believes Carlos Alcaraz can be a dominant figure in tennis "for as long as he wants" but cautioned against expecting him to challenge the grand slam records of the Big Three.

Roger Federer's haul of 20 slam titles has been overtaken by Rafael Nadal and Novak Djokovic, who both have 22 majors, but those three are streets ahead of every other men's singles player in history.

Next on the list is Pete Sampras with 14 slams, which was itself a total that many once fancied would not be beaten for decades.

Murray was for a time part of a Big Four, until he got left behind by the relentless winning of his three great rivals. Federer has retired, but Djokovic and Nadal may yet have more slam titles in them.

At the age of 19, Alcaraz is already off the mark, winning the US Open last year, and he has jumped back to world number one after winning the Indian Wells Open on Sunday.

Djokovic and Nadal will be big threats to Alcaraz's hopes of triumphing at the French Open, but the young Spaniard is no longer simply the coming player on the ATP. He has arrived, and Murray is convinced Alcaraz is the real deal and poised to stay at the top of the sport for years to come.

"He has an excellent game, an all-around game that I think will translate well onto all surfaces," Murray said.

"He's not the biggest guy, but he can serve big. He's an unbelievable mover, great athlete. Has a lot of variety in his game. Takes the ball on a lot. That's something that you hope that he keeps.

"I know from experience that it's a bit easier playing that way when you're sort of 18, 19, and there's not any scar tissue there. I hope that he maintains that style of play because it's exciting to watch."

The prediction that Alcaraz can be an all-court player, and therefore succeed on grass as well as the hard and clay courts where he has already found success, bodes well for his prospects of stacking up slams.

Murray might have faced Alcaraz in round three at the Miami Open this fortnight, but the veteran Briton, a three-time slam winner and former number one, lost his opener on Wednesday to Serbian Dusan Lajovic.

There have only been two matches on tour between Alcaraz and Murray to date, both coming in the 2021 season when they won one each.

Alcaraz is the defending champion in Miami, and a clear favourite after crushing Daniil Medvedev in the Indian Wells title match. He brings a 14-1 record for the year into the tournament.

"He's obviously so far in his young career doing better than most of the guys that have come in the last eight to 10 years," Murray said.

"I know a lot of people are expecting everyone to win 20-plus grand slams now, like that's sort of normal. I wouldn't predict that for anyone.

"I would imagine he would be right at the top of the game for, well, as long as he wants to play."

Two-time Miami Open champion Andy Murray has been eliminated in the first round of this year's event after a shock 6-4 7-5 loss to world number 76 Dusan Lajovic on Wednesday.

Murray, ranked 53rd in the world, could not find his usual return with Lajovic winning 72 per cent of second-serve points, prevailing in one hour and 38 minutes.

The Serbian claimed only his fourth win out of 16 matches on hard courts since the start of last year, holding his nerve after failing to serve out the match at 5-4 in the second set, converting his third match point in the 12th game.

Lajovic hit 21-14 winners, with Murray committing more unforced errors (15-13). The Serbian converted all three break points he generated.

Former world number six Gael Monfils was forced to retire due to a right wrist injury in his clash with French compatriot Ugo Humbert at 3-3.

Monfils, 36, was playing at only his third event since returning to the ATP Tour following seven months out due to injury.

Argentina's Facundo Bagnis defeated Brazilian qualifier Felipe Meligeni Alves 6-3 1-6 6-4, with his reward a second-round clash with last week's Indian Wells Open winner and top seed Carlos Alcaraz.

World number 50 J.J. Wolf beat world number 48 Alexander Bublik 7-5 6-3 in 79 minutes, earning a second-round clash with sixth seed Andrey Rublev.

World number 74 Martin Fucsovics sent down nine aces as he beat Argentina's Pedro Cachin 6-4 7-6 (7-2) in 107 minutes. Fucsovics will next face seventh seed Holger Rune.

Ilya Ivashka beat Daniel Altmaier 6-2 6-1 to book a second-round clash with third seed Casper Ruud, while Fabio Fognini bowed out, losing 6-4 5-7 6-4 to Jan-Lennard Struff. USA's Brandon Nakashima powered to a 7-6 (7-3) 6-3 victory over Germany's Oscar Otte.
