Danish teenager Clara Tauson set up a Luxembourg Open final showdown with Jelena Ostapenko, showing off the prowess that saw her beat Emma Raducanu in Chicago prior to the US Open.

Raducanu recovered from that setback in the final of August's Challenger tournament in the Windy City, charging to a shock Flushing Meadows triumph, but fellow 18-year-old Tauson awaits her big breakthrough at the majors.

Tauson took down a former French Open runner-up and current Olympic silver medallist in reaching the Luxembourg final, beating Marketa Vondrousova in three sets, and now must overcome a player who has been champion at Roland Garros in Ostapenko.

She prised the vital break of serve in the ninth game of the decider against Vondrousova, upping the power in her shots, before serving out for a 6-4 2-6 6-4 victory.

Tauson will be going for a second title of the year, having won the Lyon Open in March.

Defending champion Ostapenko raced to a 6-1 5-1 lead over Liudmila Samsonova but then began to misfire and had to scramble from the brink of being taken to a third set.

Ostapenko eventually prevailed 6-1 7-6 (7-4), having trailed 4-1 in the tie-break, and she will attempt to scoop a fifth WTA title on Sunday. Her most recent came at Eastbourne in the week before Wimbledon.

At the WTA tournament in the Slovenian town of Portoroz, Sunday's final will feature American Alison Riske and Italy's Jasmine Paolini.

Riske denied Slovenian Kaja Juvan a place in a home final, earning a 6-0 6-4 win in their semi-final, while Paolini sprang a shock by beating Kazakhstan's Yulia Putintseva 1-6 6-3 6-4.

Belinda Bencic made a winning return to action as the Olympic champion defeated Zarina Diyas to seal a quarter-final spot at the Luxembourg Open.

Bencic, the unlikely successor in Tokyo, triumphed in straight sets 6-1 6-3 on Thursday to tee up a last-eight encounter with Liudmila Samsonova, who the Swiss lost to in Berlin earlier this year.

It was a welcome return to form for world number 12 Bencic after her defeat to eventual champion Emma Raducanu in the US Open quarter-finals last week.

Joining the top seed in the quarters is defending Luxembourg Open champion Jelena Ostapenko, who needed three sets to overcome Arianne Hartono.

Second seed Elise Mertens also progressed, though she had to come from behind to beat Aliaksandra Sasnovich 3-6 6-2 7-5.

In Thursday's other last-16 tie, Marie Bouzkova beat Greet Minnen to round off the quarter-finals line up.

Meanwhile, Sorana Cirstea and Jasmine Paolini will meet in the Zavarovalnica Sava Portoroz quarter-finals after respective victories over Tereza Martincova and Anna Kalinskaya.

There was a sense of deja vu as Clara Tauson upset fourth seed Ekaterina Alexandrova at the Luxembourg Open.

The 18-year-old defeated the same opponent en route to claiming a maiden WTA Tour title in Lyon in March and repeated the feat here, again on an indoor court.

On this occasion, Tauson needed to come back from a break down in the deciding set to clinch a 6-4 3-6 7-6 (7-1) triumph and book her spot in the quarter-finals.

Fifth seed Marketa Vondrousova had no such trouble, the Czech a comfortable 6-2 6-4 victor over Jana Fett. Alize Cornet (8) also made the last eight with a 6-3 6-3 win over Mandy Minella, while Ludmilla Samsonova (7) needed a pair of tie-breaks to overcome Oceane Dodin.

In the first round, Zhang Shuai (6) lost in three sets to Marie Bouzkova.

At the Zavarovalnica Sava Portoroz in Slovenia, second seed Yulia Putintseva was a 6-3 6-1 winner over Katie Boulter. Alison Riske, Kristina Mladenovic and Lucia Bronzetti also made it through.

Emma Raducanu still has the hunger to continue improving following her record-breaking US Open triumph and is targeting a possible return to action at Indian Wells.

The 18-year-old became the first qualifier in history to win a grand slam when defeating Leylah Fernandez ​in straight sets in Saturday's final at Flushing Meadows.

Raducanu, ranked 150 by the WTA before beginning her three-week long tournament, did not drop a single set across her 10 matches.

That victory in New York capped a life-changing couple of months for Raducanu, who also reached the last 16 of Wimbledon in her only other grand slam appearance before withdrawing due to medical reasons.

After spending a few days away from the court and taking in some of the sights the Big Apple has to offer, the Briton is ready to start preparing for her next tournament.

"I have a few days' rest and recovery," Raducanu, who became the first British female to win a major tournament since Virginia Wade on home soil at Wimbledon 44 years ago, told CNBC's Closing Bell programme.

"I think it was needed after the last seven weeks but then I am straight back to training and hungry to get better and come back out and play some more tournaments."

Raducanu was originally due to take part in qualifying for the Chicago Fall Tennis Classic later this month, but she may instead wait for next month's delayed Paribas Open in Indian Wells, where a wildcard entry is likely.

"After the US Open I wanted to give myself this week to completely switch off from tennis because it's been an extremely intense but rewarding seven weeks," she told the WTA's official website. 

"But I've worked very hard to finish on such a high with the US Open, a whole week off was needed.

"I know I'll get back to work probably Monday or early next week to get back to training again. Schedule-wise, I'm not sure. Maybe Indian Wells, I don't know. I'm going back to London before my next tournament for sure."

Defending champion Jelena Ostapenko booked her place in the last 16 of the Luxembourg Open with a comfortable straight-sets win over Jule Niemeier.

The world number 30 came out on top 6-2 6-2 in a little under an hour to set up a meeting with Arianne Hartono, who earlier beat Anna-Lena Friedsam 7-6 (7-5) 3-6 7-6 (7-4).

Fifth seed Marketa Vondrousova also shuffled through to the next round thanks to a 6-2 6-3 triumph against Alison Van Uytvanck, while Zarina Diyas will face tournament favourite and Olympic champion Belinda Bencic next after beating Anna Karolina Schmiedlova in three sets.

Aliaksandra Sasnovich was made to work harder for her 7-5 7-6 (8-6) win against Lesia Tsurenko, with that the longest straight-sets match of 2021 so far at two hours and 30 minutes, according to the WTA.

Greet Minnen and Mandy Minella were also victorious on Tuesday, overcoming Nuria Parrizas-Diaz and Varvara Gracheva respectively.

At Zavarovalnica Sava Portoroz in Slovenia, meanwhile, home favourite Kaja Juvan eliminated top seed Petra Martic with a 6-3 6-4 win. Sweden's Rebecca Peterson was another seed to fall, going down in straight sets to Lucia Bronzetti.

Dominic Thiem believes Emma Raducanu's sensational US Open triumph might be the "greatest breakthrough performance of all time".

Raducanu, 18, overcame fellow teenager Leylah Fernandez 6-4 6-3 on Saturday to cement her place in history.

Her triumph meant she became the first qualifier – male or female – in tennis history to win a grand slam final.

She did not lose a set in 10 matches across qualifying and the main draw, becoming the first player since Serena Williams in 2014 to win the US Open without dropping a single set.

Raducanu – whose first grand slam appearance only came at Wimbledon in June – was ranked 150th in the world before the US Open, but her stunning win in New York has seen her break into the top 30.

Thiem, who missed the men's tournament with a wrist injury, was in awe of Raducanu's stunning run at Flushing Meadows and says he can scarcely recall a more impressive breakthrough in the sport.  

"There were some other great achievements in the past but with Emma Raducanu, starting in the qualifiers and then playing such great tennis and making this incredible path, it's definitely, maybe, the greatest breakthrough performance of all time," he exclusively told Stats Perform.

"It's an incredible journey if you look at the stats. She didn't lose one set the whole tournament. She came from qualifying and she didn't even play one tie-break. That's simply amazing and something that was probably never witnessed before.

"And also the way she plays, her technique, the way she moves, somehow she brought it up to a new level for the whole game and it was great to see.

"But as well, her opponent, it was so fun to watch her. I was excited for it, watching every single point on TV. And it was great not only for women's tennis, but for all sports in general."

Fourth seed Ekaterina Alexandrova needed three sets to edge past Stefanie Vogele in the round of 32 at the Luxembourg Open.

Russian Alexandrova was pushed to three sets by her Swiss opponent but ultimately outclassed Vogele to prevail 6-1 3-6 6-3 to book her place in the last 16.

She is joined there by compatriot Liudmila Samsonova, who overcame Misaki Doi 6-2 6-3, and eighth seed Alize Cornet, who beat Anastasia Potapova 6-4 6-2.

There were also wins for Clara Tauson, Jana Fett and Oceane Dodin.

At Zavarovalnica Sava Portoroz in Slovenia, meanwhile, there were victories for Viktoria Kuzmova, Sorana Cirstea and Lucia Bronzetti.

Shock US Open champion Emma Raducanu has what it takes to win Wimbledon in the future, according to British great Virginia Wade.

Raducanu, 18, beat fellow debutant finalist Leylah Fernandez 6-4 6-3 on Saturday to become the first qualifier – male or female – in tennis history to win a grand slam final.

The British sensation – the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 – did not lose a set in 10 matches across qualifying and the main draw, becoming the first player since Serena Williams in 2014 to win the US Open without dropping a single set.

The triumph also saw her become the first British woman to win a major tournament since Wade claimed the Wimbledon crown 44 years ago.

Raducanu reached the last 16 of this year's Wimbledon – her only other grand slam appearance – before pulling out of the competition due to medical reasons.

Wade, who was in attendance for the final at Arthur Ashe Stadium, believes Raducanu has all the attributes to follow in her footsteps and win British tennis' showpiece tournament during what she predicts will be a glittering career.

"I see her winning Wimbledon some time," Wade exclusively told Stats Perform. "I don't have a crystal ball, so I don't know when.

"I feel sure her time will come. She's just too good not to.

"Physically she's wonderful, she's the right height, has long legs, moves smoothly and is very quick from left to right.

"She's light on her feet, reads the ball well, her serve is terrific and her groundstrokes are solid.

"She's got balance out there and her concentration and determination are important factors as well."

Fernandez, 19, defeated top five trio Naomi Osaka, Elina Svitolina and Aryna Sabalenka along with three-time major winner Angelique Kerber on her way to Saturday's final.

And although she succumbed to a straight sets defeat, Wade believes the Canadian, along with Raducanu, will dominate the women's game for years to come.

"They're both absolutely terrific players and they enchanted everybody," she added. "Everybody was thrilled with them.

"You only get these extra special players once in a decade or once every two decades.

"In the women's game we have a really solid block of really good players. In my mind there are six to 10 players who will have to share the hardware in the next five to 10 years because they are all good. It's impossible for someone to win them all.

"Emma and Leylah will have their fair share of winning, and probably more than the others, being at the top and being feared."

Canadian teenager Leylah Fernandez feels her run to the US Open final is still "magical" despite going down to British qualifier Emma Raducanu on Saturday.

World number 73 Fernandez defeated top five trio Naomi Osaka, Elina Svitolina and Aryna Sabalenka along with three-time major winner Angelique Kerber on her way to Saturday's final.

But 18-year-old Raducanu proved too good in the decider, triumphing 6-4 6-3 over Fernandez, who turned 19 last Monday.

Fernandez had labeled her run to the final as "magical" after her three-set semi-final win over Sabalenka and she remained upbeat despite failing to claim victory against Raducanu.

"It's definitely magical," Fernandez told her post-match news conference.

"I'm very happy with myself, with the way I competed, and the play I played, the way I acted on court the past two weeks. I've improved a lot not only tennis-wise but emotionally and mentally."

Fernandez admitted the defeat "stings" but was bullish about bouncing back, believing she can continue to perform to such standards at other majors.

The Canadian had only won one WTA Tour title previously, triumphing at the Monterrey Open in March, while she had never before been further than a grand slam third round.

"I don't think it will change my life that much," Fernandez said. "I'm very lucky to have a great support team and a great family to keep me grounded.

"With these wins and this loss today, it definitely stings, but it will just make me want to work harder and stronger, just come back to every tournament with the same hunger that I came into this tournament."

During Fernandez's giant-slaying run she did not go into any match as favourite and insisted that did not play a part when she was considered to have an edge in the final against the lower-ranked Raducanu.

"It did never cross my mind," Fernandez said about being favourite in the final.

"I was just very excited to play a final. I unfortunately did not do well, and Emma did great. So that's what happened."

The Queen has led the messages of congratulations for British teenager Emma Raducanu following her "remarkable" history-making US Open triumph on Saturday.

The 18-year-old became the first-ever female or male qualifier to win a major tournament, triumphing 6-4 6-3 over fellow debutant finalist Leylah Fernandez at Flushing Meadows.

Raducanu did not drop a set throughout the tournament on her way to victory in only her second career grand slam after reaching the fourth round at Wimbledon earlier this year.

The achievement by Raducanu, who is the youngest women's grand slam finalist since a 17-year-old Maria Sharapova won at Wimbledon in 2004, was labeled as "remarkable" by the Queen.

"I send my congratulations to you on your success in winning the United States Open Tennis Championships," the Queen's message to Raducanu said. 

"It is a remarkable achievement at such a young age, and is testament to your hard work and dedication. 

"I have no doubt your outstanding performance, and that of your opponent Leylah Fernandez, will inspire the next generation of tennis players.  I send my warmest good wishes to you and your many supporters."

The Duke and Duchess of Cambridge also offered their congratulations along with United Kingdom Prime Minister Boris Johnson who praised the British sensation on social media.

"You showed extraordinary skill, poise and guts and we are all hugely proud of you," Mr Johnson wrote.

There were further tributes on social media coming from musicians Liam Gallagher and the Spice Girls, as well as football identities Marcus Rashford and Gary Lineker.

Emma Raducanu believes her shock US Open triumph highlights just how strong women's tennis is after winning Saturday's final against Leylah Fernandez ​in straight sets to become the first qualifier in history to win a grand slam.

The 18-year-old, ranked 150 by the WTA before beginning her tournament in New York some three weeks ago, prevailed 6-4 6-3 against fellow debutant finalist Fernandez.

Victory in Saturday's final caps a remarkable and life-changing couple of months for Raducanu, who also reached the last 16 of Wimbledon before pulling out of the competition due to medical reasons.

Raducanu is the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 and she feels the women's game is in strong hands.
​
"First of all, I really want to congratulate Leylah and her team – she played some incredible tennis and has beaten some of the top players in the world," Raducanu said in her on-court interview as she was handed the trophy by the legendary Billie Jean King.

"The level was extremely high and I hope we play each other in many more tournaments and hopefully finals.

"It shows the future of women's tennis and depth of the game is so great, every player in the draw has a shot at winning any tournament. 

"I hope the next generation can follow in the steps of some of the legends, for example Billie Jean right here."

Raducanu did not drop a set in her remarkable run at Flushing Meadows as she became the first British female to win a major tournament since Virginia Wade on home soil at Wimbledon 44 years ago.

Wade was in attendance for the final at Arthur Ashe Stadium – as was Tim Henman – and Raducanu will now be out to match or indeed better the success of the three-time grand slam winner.

"It means so much to have Virginia here and also Tim , British icons and for me to follow in their footsteps... it gave me the belief I could do it."

Raducanu proved too strong for world number 73 Fernandez with a perfect mix of power and precision that saw her hit 22 winners to her opponent's 18.

Only twice did Fernandez break Raducanu and the British teenager won 67 per cent of points behind her first serve.

"Leylah is always going to play great tennis and fight, that is why she is in the final, I knew I would have to dig deep," Raducanu said.

"As for this three weeks in New York, I would say having such a supportive team, the LTA my agent, and everyone back home watching on TV, thank you so much for your support over the years.

"Thank you for making me feel so at home from my first qualifying match, you have spurred me on in some difficult moments and I hope me and Leylah put on a good match today."

Emma Raducanu and Leylah Fernandez had the biggest moments of their careers – their lives, surely – coming up in a matter of moments, but both of the teenage sensations seemed calm and collected as they fulfilled some final media duties prior to heading out onto court at Arthur Ashe Stadium.

"I can't wait to get stuck in," said Raducanu, the first qualifier in history to reach a grand slam final. "I think we're just going to go out there and have fun," said Fernandez, vanquisher of US Open champions past over the course of the last two weeks.

Those questions were preceded by a commemoration of an event that occurred in New York 20 years ago to the day, the players waiting in the tunnel as tributes were paid to the lives lost on September 11, 2001, when the towers fell and the world changed.

Neither Fernandez nor Raducanu were born. Indeed, the latter does not turn 19 until November, and her opponent celebrated her 19th on Monday, a day before beating Elina Svitolina in the quarter-finals.

Whether down to youthful exuberance, or the fearlessness that inexperience can bring, both players – who last met in the second round of the juniors at Wimbledon in 2018 – lived up to their promises in the pre-match interviews, to the benefit of an audience that can only have been glued to whatever screen they watched on, not to mention the 23,000-strong crowd in attendance at Flushing Meadows.

It was a final that could have gone either way, yet ultimately in the moments it really mattered most, it was Raducanu who came out on top, a 6-4 6-3 victory sealing one of the most unlikely successes of all time.

The tone was set immediately in the first women's slam final between two unseeded players. Raducanu applying pressure and breaking serve to edge ahead.

But Fernandez has had to battle back against the odds throughout her incredible run, beating defending champion Naomi Osaka, former world number one Angelique Kerber and current number two Aryna Sabalenka. The scores were level two games later.

Raducanu had not dropped a set throughout her run, but at 30-0 down in the fifth game, it appeared to be swinging in Fernandez's favour. Four straight points from the Briton ensured that was not the case.

Special tennis was on show. Quality, control and poise worthy of players way beyond their years. After an hour, something had to give, and it was Raducanu who, at the fourth time of asking, broke serve to seal the set.

What did Fernandez have left? Was this the beginning of the end for the youngest player to beat more than one top-five opponent at the same slam since Serena Williams saw off Monica Seles, Lindsay Devenport and Martina Hingis in 1999?

Yet Raducanu found herself 2-1 and a break down three games into set two.

Fernandez could not capitalise and Raducanu returned from an 82 mile-an-hour serve to get back on the front foot. An exquisite forehand winner saw her break for 4-2.

Raducanu's Wimbledon came to an end in tears at the fourth-round stage. When she moved to within a game of grand slam immortality, there was hardly a flicker of emotion.

Fernandez said she was out to have fun, though, and a smile was back on her face as two championship points went begging for Raducanu, who then skidded across the baseline, cutting open her knee in the process.

A medical time out was required and Fernandez's joy turned to frustration. It might have been crucial, Raducanu saving two break points before an outstanding ace secured her place in history.

Ten matches, no sets dropped – Williams was the last player, in 2014, to win the US Open without dropping a set. Raducanu is also now the first woman to win a title so early in her slam career, in just her second major appearance. 

Nine years and one day since Andy Murray won his first major on the same court, a new British hero emerged.

Virginia Wade, the last British woman to reach the Flushing Meadows final in the Open Era and the 1968 champion, watched on as the iconic Billie Jean King handed the trophy over to a superstar in the making.

Big names were absent from Flushing Meadows this year, but Raducanu and Fernandez served up a final, and a result, for the ages.

Emma Raducanu became the first qualifier in tennis history to win a grand slam final after beating Leylah Fernandez 6-4 6-3 in the US Open final on Saturday.

Eighteen-year-old Raducanu, who was ranked 150 by the WTA before the tournament and had only played in one other major (Wimbledon earlier this year), enjoyed a sensational run at Flushing Meadows and proved too strong for Fernandez, 19, who was also contesting her first grand slam final.

Briton Raducanu – the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004 – showed no signs of nerves in the opening set, taking a decisive advantage.

A roller-coaster second set could have gone either way, but from a break down, Raducanu hit back to serve out the victory in an epic final between two of tennis' rising stars.

Neither player looked fazed by the magnitude of the occasion during the first set, with a series of high-quality rallies and superb winners lighting up Arthur Ashe Stadium.

Raducanu started strongly and went 2-0 up after a pulsating game on Fernandez’s serve, which lasted more than 10 minutes and had seen the Canadian save five break points before eventually succumbing.

Fernandez responded well, though, breaking back immediately before restoring parity on her own serve.

The first set went with serve until Fernandez was serving to stay in it at 5-4 down.

Raducanu squandered three set points before ultimately taking her fourth with a thumping forehand down the line, securing the lead after exactly one hour.

The British player had three break points in the second game of the second set, but Fernandez rallied to hold.

That recovery galvanised Fernandez, who broke Raducanu in the next game at the third time of asking, although her opponent broke back immediately with two wonderful backhands to see out the game.

Raducanu held her serve before opening up a 4-2 lead as Fernandez wilted under a string of excellent shots.

After a dramatic medical time out at 30-40 down on her own serve for a cut below her left knee, which left Fernandez visibly frustrated, Raducanu came back out renewed and served an ace to seal arguably the most unlikely grand slam win of all time.

British tennis was on a super Saturday high at the US Open as Emma Raducanu took centre stage – after Joe Salisbury, Gordon Reid and Alfie Hewett celebrated title success.

Salisbury completed a remarkable doubles double, adding the mixed title to the men's crown he secured on Friday, and Reid and Hewett teamed up to clinch a calendar Grand Slam in wheelchair men's doubles.

After Salisbury and American partner Rajeev Ram won the men's doubles title by beating Jamie Murray and Bruno Soares, Salisbury returned on Saturday to land another title, the fourth major of his career.

Salisbury teamed up with another American partner, Desirae Krawczyk, to see off Mexican Giuliana Olmos and Salvadorean Marcelo Arevalo 7-5 6-2 on Arthur Ashe Stadium, in the match directly before the women's final.

Raducanu, the world number 150, was going for glory in the women's singles final against another unlikely finalist in Canada's Leylah Fernandez.

If she was seeking inspiration from fellow Britons, it was in plentiful supply, with wheelchair maestros Reid and Hewett scoring a 6-2 6-1 doubles victory over Japan's Shingo Kunieda and Argentina's Gustavo Fernandez.

That meant they sealed a clean sweep of the Australian Open, French Open, Wimbledon and the US Open in 2021, becoming the first men's wheelchair duo in history to perform that feat.

France's Stephane Houdet previously won a calendar Grand Slam in the event, but he played with two different partners during the 2014 campaign, landing three titles with Kunieda and one with Joachim Gerard.

Leylah Fernandez and Emma Raducanu have taken New York by storm: Saturday's US Open final is one that nobody would have predicted and nobody should miss.

The teenagers from Montreal and London are ranked at 73 and 150 by the WTA, which runs the women's tour, and have sent a clutch of household names scuttling for the Flushing Meadows exits.

In the absence of the familiar formidable presence of Serena Williams, this remarkable duo have taken the grand slam by the scruff of the neck and made it their own, thrilling crowds with their bravura.

Ahead of their clash in Saturday's final, where a life-changing title is up for grabs, Stats Perform looks at how Fernandez and Raducanu have come so far, and the feats left for them still to achieve in the Big Apple.

RADUCANU ON A ROLL, MAKING HER FIRST MILLION

It was no secret in British tennis circles that Raducanu was a bright talent, but she prioritised her studies ahead of going on tour and this year's Wimbledon marked her first senior grand slam main-draw appearance. Precocious potential often goes unfulfilled, but Raducanu proved she had the game as well as the wit to handle the big stage as she powered through to the fourth round at the All England Club.

She still had not climbed far enough in the rankings to earn an automatic place in the US Open, so won three qualifying rounds to earn her place. Astonishingly, she has since lost just 27 games in six main-draw matches and has not dropped a set. Serena Williams was the last player to win this title without losing a set, losing 32 games in her 2014 campaign.

The 18-year-old is the first qualifier in tennis history to reach a grand slam final, and just the second woman to reach a final after fewer than three appearances in the majors, after Pam Shriver at the 1978 US Open, her second slam. Shriver lost in her final to Chris Evert, so Raducanu can set a women's tour record for winning a title at the earliest point of a grand slam career, in those terms.

Raducanu is the second Briton to reach the women's final in New York in the Open Era, after 1968 champion Virginia Wade, who has been in the New York crowd this week.

The youngster's career prize money stood at $303,376 before this tournament, and she will become a tennis millionaire whatever the result of the final. The winner takes away $2.5million and the runner-up collects $1.25million.

Previously coached by Andy Murray's father-in-law Nigel Sears, Raducanu has been working under the guidance of former British tennis player Andrew Richardson in recent months, and this run has made her the youngest women's grand slam finalist since a 17-year-old Maria Sharapova took the title at Wimbledon in 2004.

At the US Open, she has become the youngest player to reach the title match since 1999, when a 17-year-old Serena Williams beat Martina Hingis to land the first of 23 singles slams to date.

She is the lowest-ranked player to reach a women's US Open final, besides Kim Clijsters who was a former number one but unranked after coming out of a short-lived retirement to triumph at the 2009 tournament.

FERNANDEZ FLOORS THE STARS, BUT CAN SHE RATTLE RADUCANU?

While Raducanu can count Olympic champion Belinda Bencic among her victims, it has been Fernandez who has been the real giant-killer over this fortnight.

Since making an unassuming start with wins over Ana Konjuh and Kaia Kanepi to reach round three, Fernandez's run has gone into overdrive.

Sinking defending champion Naomi Osaka marked the kick-starting of one of the great charges through a draw, as the Japanese star became the first of three top-five stars to lose to the youngster, Elina Svitolina and Aryna Sabalenka being the others.

Fernandez, who turned 19 on Monday, overcame former US Open winner Angelique Kerber, too, and each of those four wins from the third round on has been epic, going to three sets each time and chock-full of tension.

She has become the youngest player to beat more than one player from the top five at the same slam since Serena Williams saw off Monica Seles, Lindsay Davenport and Hingis from the quarter-finals onwards at the 1999 US Open.

What does she have left? And can Fernandez overcome a dismal record against British players? Remarkably she has a 1-6 record at all levels against British opponents, according to the WTA, and only last month she was beaten by Harriet Dart in Montreal.

This will be the first women's grand slam final between two unseeded players. There have only ever been 21 unseeded women's finalists and seven at the US Open, and if one or both of them freezes in the spotlight it would be excusable, but that prospect appears unlikely given their shared brio and sense of belonging at this level.

Fernandez has been a masterful conductor of the crowd, and has become the third Canadian woman to reach a slam final, after Eugenie Bouchard at Wimbledon in 2014 and Bianca Andreescu at the US Open two years ago. Bouchard was runner-up to Petra Kvitova, while Andreescu beat Serena Williams.

Like Raducanu, her career earnings will be transformed whatever the outcome of the trophy match, with Fernandez having banked $786,772 before this spellbinding run.

RISE OF THE TEENAGER

This will be the fourth US Open women's final in the Open Era to be contest by two teenagers, following on from Steffi Graf's win over Gabriela Sabatini in 1988, which sealed a calendar Grand Slam, the victory by Hingis over Venus Williams in 1997, and Serena's win against Hingis two years later.

Although Raducanu and Fernandez are young, they are put in the shade somewhat by the fact a 16-year-old Hingis played a 17-year-old Venus in that 1997 final.

Overall, it will be the ninth Open Era women's final between two teenagers at the majors, and whoever wins will be the youngest champion since Sharapova's Wimbledon triumph.

NATIONAL PRIDE

Raducanu has come from almost nowhere to become British number one, which will be confirmed in the new WTA rankings next week. Should she win the title, she will move to 24 on the global list, and a defeat would mean she sits at number 32, while Fernandez will be 19th if she carries off the trophy and number 27 should she fall short.

The title would make Fernandez Canada's number one, leapfrogging Andreescu.

At around 16:00 in New York on Saturday, two teenagers will step on court, likely to the wild acclaim they richly deserve. Both might have been able to walk the grounds unnoticed a fortnight ago, but Raducanu and Fernandez are globally recognised now.

At a tournament that has been missing a galaxy of stars – the Williams sisters, Roger Federer and Rafael Nadal to name but four, and we should probably get used to that – these flamboyant greenhorns have shown tennis might just have a future as thrilling as its immediate present.
