Federico Delbonis eased through to the last 16 and Soonwoo Kwon held off a strong fight from Holger Vitus Nodskov Rune in Monday's Andalucia Open action.

Eighth seed Delbonis lost serve twice in the first set against Roberto Carballes Baena but recovered well to claim a 7-5 6-1 victory in Marbella.

He will take on Norbert Gombos, who recovered to beat Juan Ignacio Londero 6-7 (3-7) 6-1 6-3, for a place in the quarter-finals of the clay-court event.

Kwon was made to do things the hard way against junior tennis world number one Rune, who took the match all the way.

Despite trailing 3-1 in the third set, seventh seed Kwon held his nerve to force a tie-break and prevailed 6-3 3-6 7-6 (7-4).

Ricardas Berankis is also through thanks to a 6-4 6-7 (5-7) 7-5 victory over Lucas Pouille in just under three hours.

Meanwhile, seeded pair Tommy Paul and Guido Pella fell at the first hurdle in the Sardegna Open to Yannick Hanfmann and Egor Gerasimov respectively.

Eighth seed Paul recovered after squandering a 4-1 lead in a first-set tie-break but fell 7-6 (10-8) 5-7 6-3, while seventh seed Pella lost 6-4 6-0 in straight sets to Gerasimov.

Elsewhere in Cagliari, Aljaz Bedene rallied past teenager Giulio Zeppieri 1-6 7-5 7-6 (7-3) and Laslo Djere eliminated Italian wildcard Federico Gaio 6-4 6-2.

Hubert Hurkacz made history after trumping Jannik Sinner in the Miami Open final for his first ATP 1000 title.

Hurkacz became Poland's first ATP 1000 champion thanks to his 7-6 (7-4) 6-4 win over teenage sensation Sinner in Miami on Sunday.

Second seed Stefanos Tsitsipas, fourth seed Andrey Rublev, sixth seed Denis Shapovalov and 12th seed Milos Raonic were all upstaged by Hurkacz en route to the decider.

Hurkacz – the 26th seed – capped his memorable run with an impressive win against 19-year-old Italian and occasional doubles partner Sinner following one hour, 45 minutes on court.

Set to break into the ATP Tour's top 20 for the first time in his career, moving from 37 to a career-high 16th in the world, Hurkacz became the fourth player to win his first ATP 1000 trophy via the Miami Open since 1990 – following in the footsteps of John Isner (2018), Novak Djokovic (2007) and Andre Agassi (1990).

"I played [some] of the best tennis I've ever played," Hurkacz, who converted seven of 11 break-point chances against ATP 1000 finals debutant Sinner, said.

"I was solid throughout the whole tournament, and I was able to get through each round, [and] was even more pumped for the next round. I think that's something special for me.

"My tennis is getting better. We work hard with my coach, [Craig Boynton], and I'm super happy that it happened here. We still need to improve a couple of things and just try to get better each day."

Hurkacz became the first player this ATP Tour season to win two titles, having already claimed the Delray Beach Open.

The 24-year-old added: "Last year I spent so much time in Florida. I was here like almost half of the year.

"We were working pretty hard, and I think I'm used to the conditions. I think [that's] been part of the success I had here in Florida."

Next month's French Open could be postponed amid the ongoing coronavirus pandemic, according to France's minister of sports.

France entered its third national lockdown on Saturday in a bid to halt another surge of COVID-19 cases, which had threatened to overwhelm hospitals across the country. 

Professional sporting events are largely exempt from the restrictions, but minister of sports Roxana Maracineanu has suggested the French Open could be put back from its scheduled May 23 start date.

"We are in discussions with them [the French Tennis Federation] to see if we should change the date to coincide with a possible resumption of all sports and major events," she told radio station France Info.

"Today, although high-level sport has been preserved, we try to limit the risks of clusters, of spreading the virus within professional sports."

Rafael Nadal won last year's French Open, which was postponed by four months, to pull level with Roger Federer's record of 20 grand slam titles.

Hubert Hurkacz has recorded back-to-back top 10 wins to move a step closer to his maiden ATP Masters 1000 trophy with a hard-fought straight-sets win over Andrey Rublev at the Miami Open on Friday night.

The 26th seeded Pole knocked off in-form fourth seed Rublev 6-3 6-4 to book a spot in Sunday's final where he will play teenage 21st seed Jannik Sinner who defeated Roberto Bautista Agut earlier in the day.

The 24-year-old from Wroclaw had beaten second seed Stefanos Tsitsipas in the quarter-finals and continued that strong form by never allowing Rublev to settle into his game.

"It means a lot, especially after winning a title at the beginning of the year, I had a couple of rough matches," Hurkacz said in his on-court interview, referring to his January win at the Delray Beach Open in Florida.

"I’m so happy that I came over and I was still trying to improve my game and trying to be a better player. This is really huge for me."

The 23-year-old Russian had won 16 matches this calendar year including taking out last month's Rotterdam Open.

Rublev had also not lost a set all tournament and only been broken twice, yet Hurkacz broke serve three times.

The Pole also hit 25 winners and showed determination under pressure, when Rublev had a break point at 5-4 in the second set, before saving it in an epic rally and winning the game to secure the match.

World number eight Rublev said: "Today was not my day. Hurkacz played really well and he deserved to win… Now it's time to go back to work hard to be ready for the clay season."

"It’s [been a] great week for me. I did my first semis [at an ATP Masters 1000]. I'm playing really consistent. Every week I go deep in the tournament."

Sinner, 19, won a three-set match against Bautista Agut to book his spot in the decider earlier on Friday.

The young Italian world number 31 and Hurkacz know each other well.

"We played doubles together last week in Dubai,"Hurkacz said. "Now we’re playing in the final of a Masters 1000 event, so it’s going to be a fun match."

Jannik Sinner followed in the footsteps of three all-time tennis greats as he became the fourth teenager in history to reach a men's singles final at the Miami Open.

The 19-year-old Italian hit three huge backhand winners to break serve in the final game as he pulled off a 5-7 6-4 6-4 victory over Spain's Roberto Bautista Agut in their last-four clash.

It means Sinner matches Andre Agassi, Rafael Nadal and Novak Djokovic - players who went on to be ranked number one in the world - in becoming a finalist at the Masters 1000 tournament while still in his teens.

The hotly tipped world number 31 will contest a final at this level for the first time in his career on Sunday, awaiting the winner of the second semi-final between Andrey Rublev and Hubert Hurkacz.

Sinner said of his feat: "It sounds incredible. I'm very, very happy about today because obviously being the first semi-final it's not easy to play, especially on a Masters event, and playing against a very, very solid player in Roberto.

"We had a tough battle two weeks ago, and coming out as a winner today it means a lot to me."

Sinner also won that previous match, another tight three-setter, in Dubai.

Speaking on Amazon Prime, he explained how he recovered from a slow start to win the Miami tussle.

"In the beginning I think we were both a little bit tight and then we both played a little bit better," Sinner said.

"Today was not easy, it was a little bit windy, and in the end I tried to serve better and try to move him a little bit more, try to mix it up a little bit, and that was the key today.

"He was serving a few second serves in the last game and I just tried to go for it and even if I lost the game I was 5-5, so I was up in the score and it was the right decision."

Agassi, in 1990, and Djokovic, in 2007, were both teenage champions at the event, beating Stefan Edberg and Guillermo Canas respectively in the title matches.

Nadal lost to Roger Federer in the 2005 final, with the Swiss coming from two sets down to win what was then a five-set finale to the tournament. It has since gone back to being a best-of-three match.

Sinner may have benefited from Nadal, Djokovic and Federer electing to skip this year's tournament, but many believe he has the potential to follow them to the very top of the game.

Former women's world number five Daniela Hantuchova hailed Sinner's "braveness and calmness", adding: "When it really mattered, he stepped it up big time and to be able to do that at such a young age, we are looking at something very, very special here."

Greg Rusedski, runner-up at the 1997 US Open, added on Amazon's broadcast: "Rafa was the youngest to be in the Miami finals. Mentally they have a lot in common. Different styles but just bold and brave."

Second seed Stefanos Tsitsipas has blown a strong position to be knocked out of the Miami Open by world number 37 Hubert Hurkacz in three sets on Thursday night.

The Polish 26th seed lost the first set and trailed 0-2 in the second with Tsitsipas having two break points, before fighting back for an outstanding 2-6 6-3 6-4 triumph.

The victory seals Hurkacz's place in his first-ever Masters 1000 semi-final where he will face Russian fourth seed Andrey Rublev.

On Thursday night, Rublev won 7-5 7-6 (9-7) over Sebastian Korda, ending the young American's exceptional run in Miami.

Tsitsipas's demise was the major story on Thursday, having only dropped one set in his previous three matches in Miami.

The Greek world number five was in form, having made February's Australian Open semi-finals and last week's Mexican Open final.

Tsitsipas was in control until Hurkacz dialed up his aggression in the second, producing a brilliant flick after the Greek's volley to take advantage at 2-2.

Hurkacz got the crucial break at 2-2 in the third when the Greek coughed up a mistake by missing a routine smash.

The 24-year-old Pole also sent down 15 aces in a breakthrough win.

"It is so big," Hurkacz said in his on-court interview about reaching his maiden Masters 1000 semi-final.

"I was trying to keep fighting and that’s what I did. [I am] super pumped and happy that I was able to turn this match around.

"He was returning very well and I had to play a lot of rallies. At the beginning of the match, I tried to go for too much, so then I was trying to adapt my game a little bit."

Rublev claimed his 20th ATP Tour win for the calendar year, the most of any player ahead of Daniil Medvedev and Tsitsipas with 17, to book his semi-final spot against Hurkacz.

The defeat ended 20-year-old Florida resident Korda's superb run, where he claimed his first top 20 win against Fabio Fognini and first top 10 victory against Diego Schwartzman.

Top seed Daniil Medvedev powered his way into the Miami Open quarter-finals, along with Stefanos Tsitsipas and Andrey Rublev on Tuesday.

Medvedev won in straight sets against unseeded American Frances Tiafoe, hitting 24 winners.

Second seed Stefanos Tsitsipas won in straight sets against 24th seed Lorenzo Sonego, although the second went to a tie-break which the Greek dominated.

World number eight Andrey Rublev got past Marin Cilic in straight sets to book his last-eight spot.

Fifth seed Diego Schwartzman was the major casualty on Tuesday, losing to unseeded American Sebastian Korda in three sets. Seeds Josh Isner, Milos Raonic and Taylor Fritz also exited.

 

TOP SEED EASES INTO LAST EIGHT

World number two Medvedev was too good for Tiafoe in a 6-4 6-3 victory.

Medvedev improved his 2021 record to 17-2, sending down 11 aces with a dominant first-serve display while taking three of his four break points.

The 2021 Australian Open runner-up will meet seventh seed Roberto Bautista Agut in his maiden Miami Open quarter-finals appearance.

"It was definitely a tough match," the Russian said in his post-match on-court interview. "I am just looking forward to tomorrow. Roberto is a hell of a player.

"I feel like sometimes, when I have practised with him and played against him, that his ranking should be higher. There are reasons why it is not and I am going to try to do something with it tomorrow."

STEFANOS SIZZLES PAST SONEGO

Tsitsipas kept up his good form after making last month's Australian Open semi-finals, by booking his first Miami Open quarter-final appearance.

The Greek world number five defeated Sonego 6-2 7-6 (7-2) with a clinical performance to keep alive his dream of a maiden ATP Masters title.

Tsitsipas won in just over an hour and a half, proving too good on serve, having not offered up one break point and winning 89 per cent of first-serve points.

He was also too good with his return for the Italian, winning 35 per cent of the points on Sonego's serve.

The Greek will take on Polish 26th seed Hubert Hurkacz in the last eight, after he knocked out 12th seed Raonic 4-6 6-3 7-6 (7-4).

 

FIFTH SEED TOPPLED BY KORDA

World number nine Schwartzman was knocked out in three sets by Korda 6-3 4-6 7-5 as he continues his super run.

Florida resident Korda, 20, reached his maiden ATP 1000 quarter-final, showing fight after the Argentinian raised his game in the second set, winning after an early break in the last.

Rublev made light work of former US Open champion Marin Cilic, triumphing 6-4 6-4.

Bautista Agut got past 18th seed Isner 6-3 4-6 7-6 (9-7), while Jannik Sinner defeated Alexander Zverev's conqueror Emil Ruusuvuori 6-3 6-2.

Alexander Bublik, seeded 32nd, sent down 23 aces as he beat Taylor Fritz 6-7 (5-7) 6-3 6-4.

 

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.

Russian star Daniil Medvedev overcame painful cramps and Alexei Popyrin to battle his way into the Miami Open round of 16.

Medvedev looked in all sorts of trouble against the Australian, but the world number two and top seed survived at the ATP 1000 tournament on Sunday.

Canadian sensation Felix Auger-Aliassime was sent packing by former champion John Isner in Miami.

 

MEDVEDEV ADVANCES… SOMEHOW

Australian Open and US Open runner-up Medvedev could barely walk during his gruelling three-set win against Popyrin.

Medvedev let three match points slip away in the second set, having led 5-2, before cramp set in.

In humid conditions, Medvedev was forced to rely on his serve as he limped around the court.

"Winning a Grand Slam final in straight sets doesn't feel the way I felt after the match point today," he said. "A match to remember for sure."

"I felt like my legs were not following me anymore," Medvedev said. "The only thing I was thinking about is not to fall down, because if you fall down, I don't think I would be able to get up. There were a few moments I just wanted to lay down and say, 'OK, it's over.' That's the thing I couldn't accept myself to do."

Awaiting Medvedev is Frances Tiafoe after he outlasted 16th seed Dusan Lajovic 1-6 7-5 6-3.

 

AUGER-ALIASSIME TOPPLED

A new year, but same result for 11th seed Auger-Aliassime, who was beaten 7-6 (7-5) 7-6 (7-5) by Isner.

Isner defeated Auger-Aliassime en route to the championship match in Miami two years ago and the big-serving American repeated the feat.

The only former Miami champion in this year's field, Isner remains unbeaten in tie-breaks at Hard Rock Stadium, winning all 11 since the tournament relocated in 2019.

"It was a big test for me. There's probably not many places in the world where I like my chances against Felix," Isner said. "I'm kind of lucky to play him here in Miami, where I like it a lot. If I were to play him on clay somewhere in Europe, it'd probably be a different story."

Next up is seventh seed Roberto Bautista-Agut, who beat Jan-Lennard Struff 4-6 6-3 6-2.

Elsewhere, Jannik Sinner, Taylor Fritz, Emil Ruusuvuori and Alexander Bublik also advanced.

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.

Third seed Alexander Zverev was sensationally dumped out of the Miami Open second round as Finnish 21-year-old Emil Ruusuvuori claimed his second top 10 win of his career.

Russuvuori bounced back after losing the first set, changing his tactics and overwhelming the German on Friday to set up a third round meeting with Mikael Ymer.

Ninth seed Grigor Dimitrov also bowed out, going down to Briton Cameron Norrie, while eighth seed David Goffin lost to James Duckworth.

World number two and top seed Daniil Medvedev eased past Lu Yen-hsun, while 11th seed Felix Auger-Aliassime, Karen Khachanov and John Isner all progressed.

 

TURNAROUND STUNS THIRD SEED

Zverev may have won last week's Mexican Open and the opening set 6-1 against Ruusuvuori but the tables turned quickly as the Finn produced one of the best displays of his career to date.

The 83rd ranked Finn moved regularly to the net and was aggressive in his approach, leaving Zverev rattled before winning 1-6 6-3 6-1 in a stunning momentum shift.

"I don't even know myself," Ruusuvuori said in his on-court interview when asked how he turned the match around.

"I wasn't feeling very comfortable in the first set and I was making a lot of unforced errors but slowly in the second I was starting to feel a bit better... Of course, it's one of the biggest wins in my career so it feels good."

He'll next face Ymer who knocked out 27th seed Nikoloz Basilashvili.

 

NINTH SEED BUNDLED OUT

Former world number three Dimitrov was ousted from the Miami Open on Friday, losing 7-5 7-5 to 56th ranked Norrie.

The Bulgarian took an early break and served for the first set at 5-3 but Norrie showed his mettle to break back twice to take the opener.

Norrie sent down 10 aces and was strong on serve throughout, claiming a significant win for his burgeoning career.

“It’s huge,” Norrie said. “He’s had a good start to the year. It was such a physical match at the start. He came out really fast and he set the tone at the beginning of the match. Massive one for me and I take a lot of confidence from it.”

Norrie's win sets up a third round meeting with American Taylor Fritz who beat Marcos Giron 6-2 6-2.

 

DANIIL DOMINATES, GOFFIN SHOCK

Australian Open runner-up Medvedev made light work of Lu, winning 6-2 6-2 to book a third round match with Australian 21-year-old Alexei Popyrin.

Medvedev won in less than an hour, hitting 24 winners and nine aces and making few errors in a clinical display.

Canadian 11th seed Aliassime proved too good for Pierre-Hugues Herbert 6-4 6-4, setting up a third round meeting with 18th seed John Isner who got past qualifier Mackenzie McDonald.

Seventh seed Roberto Bautista Agut progressed by virtue of a walkover against Lloyd Harris who had a wrist issue.

Eighth seed Goffin lost to world number 104 Duckworth 6-3 6-1 in a boilover.

Lorenzo Musetti built on his good form with a first-round victory over Michael Mmoh at the Miami Open on Thursday.

Emerging star Musetti defeated American qualifier Mmoh 6-4 6-4 to set up a second-round meeting with 23rd seed Benoit Paire.

Former US Open champion Marin Cilic also progressed in a three-set victory over Federico Coria, while Thanasi Kokkinakis, Sebastian Korda, Tennys Sandgren and Jordan Thompson were other winners.

Former top-five player Kevin Anderson was among those to bow out in the first round of the ATP 1000 event.

 

STAR ON THE RISE

Italian teenager Musetti continued his rapid rise with a hard-fought victory over Mmoh.

The 19-year-old Musetti reached the semi-finals of last week's Mexican Open, where he beat both Diego Schwartzman and Grigor Dimitrov en route to the semi-finals.

This week, Musetti battled past wildcard Mmoh in one hour, 38 minutes.

"Last week was a fantastic run in Acapulco," Musetti said in his on-court interview. " I played a really good match, it was a tough match.

"I think my lethal weapon is the backhand down the line."

 

CILIC SLICE OF FORTUNE

Former world number three Cilic secured his place in the second round with a 6-3 2-6 6-4 victory against Federico Coria.

However, Cilic – the 2014 US Open winner – had a huge slice of luck to claim a break back in the first.

The Croatian got lucky down a break at 2-1 but up 30-40 in the first when he mishit his overhead attempt, striking his frame and bobbling over for a drop shot winner to level.

"It was important for me to keep my head down, keep the focus and just try to get the best level I could today," Cilic said.

 

FOND MEMORIES FOR THANASI

Australian qualifier Kokkinakis' fond memories in Miami returned with a 6-3 6-3 win over Shintaro Mochizuki as he continues his positive return from a shoulder injury.

Kokkinakis beat then-world number one Roger Federer in Miami in 2018.

Korda won his Miami Open debut match, triumphing 6-3 6-0 over Radu Albot to set up a meeting with 10th seed Fabio Fognini.

Jordan Thompson will face Milos Raonic after accounting for Federico Delbonis 7-6 (8-6) 6-4 in two hours, 12 minutes.

Sandgren – a two-time Australian Open quarter-finalist – got past Pedro Martinez 6-4 2-0, with the Spaniard retiring.

Wimbledon and US Open runner-up Anderson was a surprise casualty, going down 7-6 (8-6) 7-5 to lucky loser Damir Dzumhur.

"I know that my game can be much better than what I'm showing right now and my position in the ATP Rankings can be much better," Dzumhur said.

Vasek Pospisil launched a stunning tirade during his three-set defeat to American qualifier Mackenzie McDonald in the first round of the Miami Open on Wednesday.

The Canadian former world number 25 was docked a point for verbal abuse, subsequently conceding the first set, before a meltdown during the change of ends.

Pospisil used a profanity in reference to ATP chairman Andrea Gaudenzi when speaking to chair umpire Arnaud Gabas.

“[Gaudenzi was] screaming at me in a player meeting for trying to unite the players — for an hour and a half," Pospisil said to Gabas. "If you want to default me, I’ll gladly sue this whole organisation.”

He did fight back to win the second set but ultimately lost to McDonald 6-3 4-6 6-3.

Pospisil, who is nowadays ranked 67th, was joined among the first-round exits by last week's Mexican Open semi-finalist Dominik Koepfer, who went down 6-1 6-4 to wildcard Hugo Gaston as he claimed his first career Masters 1000 win.

Sam Querrey, ranked 63rd, also bowed out 6-3 6-4 to Lu Yen-hsun, who will meet world number two Daniil Medvedev in the second round.

YOUNGSTER BEATS VETERAN

Australian youngster Alexei Popyrin secured his maiden win at the Miami Open, knocking out the oldest player in the draw Feliciano Lopez 6-4 7-6 (7-4).

Popyrin, 21, claimed his first ATP Tour title last month in Singapore and backed that up with a strong display against the 39-year-old former top 20 Spaniard.

Recent Open 13 Marseille runner-up Pierre-Hugues Herbert got past Portugal's Pedro Sousa 6-1 6-3, while South Africa's Lloyd Harris defeated Emilio Nava 6-4 7-6 (9-7).

Frances Tiafoe won in the final match of Wednesday, coming from behind to beat Stefano Travaglia 5-7 6-4 6-2.

 

COMEBACK CAM

Brit Cameron Norrie produced a heroic final-set fightback to claim his spot in the second round, where he will face Grigor Dimitrov.

Norrie trailed 5-1 in the third set against Yoshihito Nishioka, before winning 6-1 3-6 7-5, winning the last six games to clinch victory.

The 56th-ranked Brit sent down eight aces in the victory, although he got the edge on return and converted seven of his 10 break points.

SECOND ROUND

Top seed Medvedev will face Lu on Thursday, while third seed Alexander Zverev will take on Finland's Emil Ruusuvuori.

Norrie will meet Dimitrov, while 11th seed Felix Auger-Aliassime faces Herbert and eighth seed David Goffin will take on James Duckworth.

Harris has a match-up against seventh seed Roberto Bautista Agut.

Andy Murray will not feature at the Miami Open after withdrawing from the tournament because of a groin injury.

The former world number one and three-time grand slam champion has featured only twice on the ATP Tour this season, losing in the first round in Montpellier before going one better in Rotterdam, where he was beaten by Andrey Rublev.

He withdrew from this month's Dubai Tennis Championships to be with his wife as she gave birth to their fourth child.

And his return to action has been delayed again, with Murray missing out on a tournament he has won twice.
