Serena Williams' former coach Rick Macci does not foresee a dream US Open triumph for the retiring legend, but believes the Flushing Meadows crowd could help her enjoy a strong run.

Williams, who announced she was "evolving away" from tennis earlier this month, will begin her final US Open campaign against Danka Kovinic on Monday.

While the 40-year-old's tally of 23 grand slam titles is the most of any player in the Open Era (since 1968), she remains one victory short of Margaret Court's all-time record of 24. 

But Macci, who coached both Williams and older sister Venus at the beginning of their trophy-laden careers, struggles to see her adding one final title before signing off.

"They asked me can Serena Williams win the US Open and I said she already has, six times," Macci told Stats Perform. 

"Can she? It's highly unlikely simply because people aren't afraid of her, the movement and confidence aren't like it was because she hasn't played, she hasn't played that much in the last year and you need to play to get your footwork and stamina. 

"The fighting spirit, the Compton street fight and the heart is there. If she gets a good draw, she could beat some people. I like how she played against [Emma] Raducanu [a 6-4 6-0 loss in Cincinnati earlier in August], I like that she's more aggressive, but this takes time. 

"If she can win a few matches who knows what could happen? That crowd in New York is going to take her down memory lane and make her even more competitive, who knows what's going to happen to the person on the other side of the net?

"That's why I was so impressed with Raducanu, the way she handled that moment, she played the best match she had in a year. 

"It cuts both ways but it's highly unlikely she can win the Open. 

"She's not even looking at it like that, she's letting everyone savour the moment and going out on her terms and it's going to be must-see tv."

Asked who he thought would emerge victorious at Flushing Meadows, Macci tipped another American to win on home soil, adding: "I'd love to see Coco Gauff because I know the family and I think she has wonderful potential.

"Iga [Swiatek] is vulnerable now because when you win 35 in a row, you feel like you just show up you're going to win. 

"Now that she's lost a few there's a little doubt there. It's wide open, I'm going to go out on a limb and I'm taking Coco Gauff."

As for the men's draw, which appears balanced after Novak Djokovic's non-vaccinated status prevented him from travelling to New York, Macci thinks third seed Carlos Alcaraz could be set for a maiden grand slam win.

"I've already gone out there and talked about this, Carlos Alcaraz is a generational player, he's going to transcend the game," Macci added.

"I've already had people blow back on me like, 'why isn't he winning?' Trust me, he just turned 19 and is [number] four or five in the world, I think he'll win multiple grand slams and he's the next real deal and he's my favourite to win the US Open on the men's side."

Djokovic is not alone in missing the US Open, with Roger Federer also absent as he continues his recovery from knee surgery, while Rafael Nadal is making his first appearance at the slam since triumphing in 2019.

Four different men have tasted success at Flushing Meadows in the last four years, while each of the last three editions have featured different women's singles champions, and Macci believes the issues endured by several ageing greats have made tennis more competitive.

"I think a lot of people are heading toward exit stage left and they're not quite at the top, [such as] Federer, or maybe there's the vaccination and maybe Nadal you're not quite where you were and [Andy] Murray," he added.

"Then you've got Serena, you've got these people who are household names that are out of the equation, more people are coming in and it changes everything when you don't have those roadblocks at the round of 16. 

"You're looking at the semis when before, Federer, Nadal, Djokovic and Murray just dominated. There was a time when those four were always in the semis. The women's you could almost predict, now you can't.

"It has nothing to do with the US Open because the young lady that won Wimbledon [Elena Rybakina], you never heard of her. It's just wide open and it's going to take a while to stabilise everything." 

Two-time major winner Simona Halep continues to find form ahead of the upcoming US Open with a 6-4 7-6 (7-2) victory over Coco Gauff clinching her spot in the Canadian Open semi-finals.

Halep defeated 10th seed Gauff, who had beaten Naomi Osaka, Elena Rybakina and Aryna Sabalenka this week, in one hour and 47 minutes.

The Romanian 15th seed was broken five times and sent down eight double faults, but found the edge with speed, finesse and power.

The win means Halep has won the third most matches (36-10) on the WTA Tour this season, behind only top-ranked Iga Swiatek (49) and Wimbledon finalist Ons Jabeir (37).

Halep's improved form comes after she teamed up with Serena Williams' ex-coach Patrick Mouratoglou in April following a difficult 2021 season.

"Before I met him I was super down with my motivation," Halep told reporters. "I couldn't really work, keep working. I was almost done with tennis. He brought this fire back and the motivation. He trusted that I still can play good tennis and he transferred this to me."

The 2018 French Open and 2019 Wimbledon champion added: "Physically I'm good. Mentally I'm good, so I think it's all positive."

Halep, who won the Canadian Open in 2018, has reached the semi-finals for the fifth time in her career where she will take on seventh seed Jessica Pegula.

Pegula got past Yulia Putintseva 6-3 6-3 in one hour and 21 minutes. Qualifying for the last four at the Canadian Open for the second straight year.

Brazilian Beatriz Haddad Maia maintained her Canadian Open run, having ousted Swiatek in the third round and local favourite Leylah Fernandez in the second, with a 2-6 6-3 6-3 victory over Tokyo Olympics gold medalist Belinda Bencic in two hours and 11 minutes.

Haddad Maia became the first Brazilian to reach the semi-finals of a WTA 1000 tournament. She will face Karolina Pliskova in the semi-finals after the Czech 14th seed beat Qinwen Zheng 4-6 6-4 6-4.

Coco Gauff will reach the highest ranking of her career after the 18-year-old defeated world number six Aryna Sabalenka 7-5 4-6 7-6 (7-4) in the third round of the Canadian Open on Thursday.

Gauff, who has never been ranked higher than her current spot of 11th, will overtake Emma Raducanu and likely Daria Kasatkina to move up to ninth when the next rankings are released after prevailing in an exceptionally tight match against her Belarussian opponent. 

Incredibly, both Gauff and Sabalenka won exactly 131 points each, posting identical success rates on service points (77-of-131) and return points (54-of-131).

Gauff will be considered one of the favourites in the tournament after world number one Iga Swiatek was sensationally eliminated by Brazil's Beatriz Haddad Maia. Swiatek was sloppy, committing nine double faults to just one from her opponent.

Two-time grand slam winner Simona Halep defeated rising Swiss talent Jil Teichmann 6-2 7-5, utilising her dominant first serve to get the job done. Halep converted 82 per cent (32-of-39) of her accurate first serves into points, compared to just 59 per cent (29-of-49) for Teichmann.

World number seven Jessica Pegula had to save a match point on her way to a comeback 3-6 6-0 7-5 win against reigning Canadian Open champion Camila Giorgi, booking her quarter-final clash against Yulia Putintseva after the Kazakhstani beat Alison Riske 6-3 7-5.

Third seed Maria Sakkari went down 1-6 7-6 (11-9) 3-6 against 14th seed Karolina Pliskova, and the Czech will take on China's Qinweng Zheng after she eliminated Canada's last remaining contender Bianca Andreescu 7-5 5-7 6-2.

In the final match of the night, Tokyo Olympics gold medalist Belinda Bencic was incredibly impressive against world number eight Garbine Muguruza, prevailing 6-1 6-3.

The Serena Williams' farewell tour in Toronto is over after she was knocked out of the Canadian Open 6-2 6-4 by 12th seed Belinda Bencic on Wednesday.

Williams, playing for the first time since declaring on Tuesday her intention to retire after this month's US Open, was no match for Tokyo Olympics gold medalist Bencic.

The 23-time major winner was unable to claim back-to-back WTA singles wins for the first time since last year's French Open, having defeated Nuria Parrizas-Diaz for her first victory in 430 days on Monday.

Bencic triumphed in one hour and 17 minutes, winning 84.2 per cent of first-serve points and converted five of eight break points throughout the match.

Williams' power was on show with 13 winners, but Bencic was physically more capable and decisively managed 25 winners with only 13 unforced errors.

Elsewhere, 2019 US Open winner and local hope Bianca Andreescu edged Alize Cornet in a see-sawing clash in the evening, winning 6-3 4-6 6-3 in two hours and 26 minutes.

Fourth seed Paula Badosa and fifth seed Ons Jabeur, who was last month's Wimbledon runner-up, were forced to retire due to injury.

Spanish 24-year-old Badosa withdrew against Yulia Putintseva 7-5 1-0 due to muscle cramping, while Zheng Qinwen had a walkover against Jabeur 6-1 2-1 due to abdominal pain.

Top seed Iga Swiatek brushed aside Ajla Tomljanovic 6-1 6-2 in 64 minutes. The win means Swiatek is the first player to win 15 WTA 1000 matches in straight sets in a row since 2009.

Canadian 13th seed Leylah Fernandez also bowed out, going down 7-6 (7-4) 6-1 to Brazil's Beatriz Haddad Maia, who will face Swiatek in the third round.

Second seed Anett Kontaveit lost 6-4 6-4 to Jil Teichmann in one hour and 27 minutes. Teichmann will next face Simona Halep who won in 71 minutes against Zhang Shuai 6-4 6-2.

Sixth seed Aryna Sabalenka got past Sara Sorribes Tormo 6-4 6-3 to set up a third-round meeting with Coco Gauff after she defeated Wimbledon champion Elena Rybakina 6-4 6-7 (8-10) 7-6 (7-3) in an epic that lasted two hours and 49 minutes.

Jessica Pegula won 6-2 7-5 over American qualifier Asia Muhammad to progress through to face Camila Giorgi after she knocked off Elise Mertens 7-3 7-5.

Third seed Maria Sakkari triumphed in three sets 6-2 4-6 6-2 over Sloane Stephens and will face Karolina Pliskova next after the Czech beat Amanda Anisimova 6-1 6-1.

Eighth seed Garbine Muguruza won 6-4 6-4 against Kaia Kanepi and Alison Riske toppled 16th seed Jelena Ostapenko 7-6 (7-2) 0-6 7-5.

Coco Gauff described Serena Williams as "the reason why I play tennis" as she paid tribute to the soon-to-retire great, declaring: "There will never be another Serena."

Williams, a 23-time grand slam champion, announced in a piece in Vogue on Tuesday that she would soon retire.

The 40-year-old did not provide a firm date for the end of her career, but hinted that she could bow out after the US Open, which begins at the end of August.

Williams had won her first singles match in over a year on Monday at the Canadian Open, yet she wrote of the need to now prioritise her family.

And Gauff, playing at the same event in Toronto, was not short of praise for a legend of the sport.

"She's just been playing forever, my whole life," Gauff said after beating Madison Brengle.

"The legacy that she's left throughout her tennis career is something that I don't think any other player can probably touch.

"I think that the legacy that she'll continue to leave throughout her life is something that can inspire many more generations."

Gauff, a highly talented 18-year-old, has no interest in any tag as the 'next Serena', although she can take inspiration from Williams in dealing with such pressure.

"I've learned a lot from them [Serena and sister Venus]," Gauff said.

"People always tell me that you're going to be 'next whatever', blah, blah, blah, and Serena has been considered the GOAT [greatest of all time] for at least the second half of her career, and she never succumbed to that pressure.

"I think she overcame it, and I think that's something I take from her and try to learn from it. Not that I'm at her level and experiencing the same pressure she is, but in the moment I try to emulate that.

"For me, I grew up watching her. That's the reason why I play tennis, and tennis being a predominantly white sport, it definitely helped a lot, because I saw somebody who looked like me dominating the game, and it made me believe I could dominate, too.

"She's the GOAT. And undisputed, too, in my opinion. But I don't think that's an opinion, it's a fact.

"Serena, for me, is the GOAT. The GOAT of all GOATs. There will never be another Serena."

Coco Gauff shined on the opening day of the Canadian Open on Tuesday, defeating American compatriot Madison Brengle 6-1 6-3 to move to a record of 14-4 from her past 18 matches.

Gauff, who has not lost to anyone ranked lower than world number 22 Amanda Anisimova since the Australian Open, continued that impressive record by cruising past world number 62 Brengle, winning 58 per cent (34-of-59) of her return points in a dominant showing.

Anisimova, who eliminated Gauff from Wimbledon, also made it through her first match unscathed as she defeated hometown Canadian Carol Zhao 6-1 6-3.

China's Qinweng Zheng put another dagger into the Canadians with her 3-6 7-6 (7-5) 6-4 win over Rebecca Marino, but Bianca Andreescu gave the fans something to cheer for as she upset world number nine and winner of this past week's Silicon Valley Classic Daria Kasatkina 7-6 (7-5) 6-4.

Spain's Sara Sorribes Tormo prevailed against American Claire Liu 7-6 (7-4) 2-6 7-6 (7-5) in a three-and-a-half-hour battle of attrition, while Australian qualifier Ajla Tomljanovic upset world number 16 Veronika Kudermetova 6-4 2-6 7-6 (7-4) in two-and-a-half hours.

It was a disappointing showing from world number 10 Emma Raducanu as she went down 7-6 (7-0) 6-2 to the reigning champion of this event, Italy's Camila Giorgi.

Naomi Osaka also will need an early flight home after being forced to retire against Estonia's Kaia Kanepi, pulling the plug due to a persistent back injury while trailing 7-6 (7-4) 3-0.

In the late session, Olympic gold medalist Belinda Bencic successfully navigated the challenge of Tereza Martincova 6-4 6-2 to book a second round fixture against Serena Williams, and world number four Maria Sakkari survived a scare to finish strong and defeat Sloane Stephens 6-2 4-6 6-2.

Despite being ranked fourth in the world, Paula Badosa came into her quarter-final showdown with the red-hot Coco Gauff as the underdog, but she played like a favourite en route to a 7-6 (7-4) 6-2 victory.

Usually one of her stronger weapons, Gauff's serve was a liability on Friday, with six double faults in the first set alone to drop the opening frame despite breaking Badosa twice.

In the second set, while Badosa was converting 92 per cent (11-of-12) of her accurate first serves into points, Gauff's figure was down at 53 per cent (eight-of-15) as the Spaniard's return game was at its best.

Badosa will meet seventh seed Daria Kasatkina in the semi-final after the Russian beat Belarus' Aryna Sabalenka 4-6 7-5 6-0. The longer the match went, the less effective Sabalenka became with her ability to return serve.

In the first set, which Sabalenka won, she was successful in 53 per cent (19-of-36) of the points against Kasatkina's serve, and that number plummeted to 14 per cent (two-of-14) in the decider.

Third seed and Wimbledon finalist Ons Jabeur was eliminated by ninth seed Veronika Kudermetova 7-6 (7-5) 6-2, and she will meet unseeded American Shelby Rogers in the second semi-final after she defeated Amanda Anisimova 6-4 6-4.

Meanwhile, in Washington at the Citi Open, Emma Raducanu felt the effects of her gruelling match 24 hours prior as she went down 7-6 (8-6) 6-1 to Liudmila Samsonova.

On Thursday, Raducanu played in the longest two-set match of the WTA season as she eventually made her way through two tiebreakers against Camila Osorio in two hours and 49 minutes, and she ran out of steam after another tough tie-break against Samsonova.

Samsonova will play China's Xiyu Wang in the semi-final after another upset, knocking out fourth seed Victoria Azarenka in convincing fashion 6-1 6-3.

Estonia's Kaia Kanepi booked her place in the second semi-final after a 6-7 (4-7) 6-4 6-3 win against Anna Kalinskaya, where she will meet Daria Saville after the Australian got the better of Canada's Rebecca Marino 6-1 7-5. 

Coco Gauff was too sharp with her return game for Naomi Osaka in the second round of the Silicon Valley Classic on Thursday, coming away with a 6-4 6-4 win.

Gauff – the world number 11 and tournament's sixth seed – created 12 break point opportunities in the match, while only allowing one for Osaka, despite eight double-faults.

Ultimately, Gauff won 41 per cent (29-of-71) of the points off Osaka's serve, while converting 85 per cent (28-of-33) of her successful first serves into points.

Earlier in the day in a major upset, top seed Maria Sakkari was eliminated in straight sets 6-1 6-3 by American Shelby Rogers. 

The world number three struggled with her serve throughout, landing only 45 per cent of her first serves, and winning just 52 per cent (12-of-23) of those points.

World number six Aryna Sabalenka needed three sets to defeat unseeded American Carolina Dolehide 5-7 6-1 7-5, and Russia's Veronika Kudermetova had less trouble dispatching Claire Liu 6-2 7-5 to set up an exciting match with Ons Jabeur in the quarter-final.

Meanwhile, in Washington at the Citi Open, Emma Raducanu played in the longest two-set match of the WTA season, defeating Camila Osorio 7-6 (7-5) 7-6 (7-4) in two hours and 49 minutes.

Both women created at least a dozen break point opportunities, with four total breaks each as the young British star battled blisters on her hands.

Raducanu will play Liudmila Samsonova after the Russian eliminated Australia's Ajla Tomljanovich 4-6 6-3 6-2.

In the last match of the day, China's Xiyu Wang got the better of Croatia's Donna Vekic 4-6 7-5 6-1, and she will meet the winner between Tereza Martincova and Victoria Azarenka in the quarter-final.

Naomi Osaka delivered a terrific third set to defeat China's Qinweng Zheng 6-4 3-6 6-1 in the opening round of the Silicon Valley Classic.

Osaka's serve was sharp and it carried her through the match, with 11 aces to Zheng's three, while giving up one break of serve and securing three breaks herself.

After Zheng fought back to win the second set, Osaka was the steady head in the decider, allowing her opponent to implode with three double-faults in crucial points to collect her first win since April.

Osaka will meet Cori Gauff in a star-studded second-round matchup after Gauff dominated Anhelina Kalinina 6-1 6-0.

She was simply too powerful for her Ukrainian opponent, winning 89 per cent (25-of-28) of her first serves to never give Kalinina a chance.

Canada's Bianca Andreescu was eliminated by American Shelby Rogers 6-4 6-2, while Russia's Veronika Kudermetova won a hard-fought battle against Italy's Camila Giorgi 7-6 (7-2) 4-6 7-5.

Meanwhile, in Washington at the Citi Open, Emma Raducanu looked in good touch as she handled the challenge of Louisa Chirico 6-4 6-2 to advance to the second round.

Raducanu will meet Colombia's Camila Osorio after she beat American Sofia Kenin 7-6 (7-2) 6-1, and top-20 talent Victoria Azarenka had no issues against Dayana Yastremska to win 6-4 6-0.

Australian Ajla Tomljanovic continued her strong run of form with a convincing 6-1 6-4 win against American Sloane Stephens, and the Czech Republic's Tereza Martincova recovered from a horrible first set to defeat Xinyu Wang 0-6 6-4 6-4.

Germany's Andrea Petkovic cruised to a 6-2 6-2 win against Denmark's Clara Tauson, and Russia's Anna Kalinskaya defeated American Madison Brengle 6-3 6-0.

Amanda Anisimova celebrated the "most special day" of her career after her long game came to the fore once again when beating Coco Gauff.

Anisimova came from a set down to beat her compatriot 6-7 (4-7) 6-2 6-1 on Centre Court at Wimbledon.

The American world number 25 has now won 12 matches in three sets in 2022, which is the joint-highest tally on the WTA Tour so far this season, level with Beatriz Haddad Maia.

"It was my first time playing on Centre Court and this is the most special day of my career," the 20-year-old told BBC Sport following her success over this year's French Open runner-up.

"It's just a huge privilege to play on this court playing Coco. She is an amazing player, got to the final of a grand slam, so I wanted to soak up the moment. Winning is so special, especially in front of a full crowd.

"There are so many American players doing well and I'm proud of my country and how we have been doing. It was really exciting to have an all-American clash on this court so it was really special."

Next up for Anisimova in the round of 16 is Harmony Tan, who has been one of the standout stories from the first week at The All England Club.

Tan defeated Serena Williams in the first round, following that triumph up with wins over Sara Sorribes Tormo and Katie Boulter.

When Wimbledon ended last year, there were two great takeaways from the tournament: Novak Djokovic would soon be pulling away in the grand slam title race and Ash Barty was beginning a new era of dominance.

Both seemed to be knock-ins, and yet neither has come to pass. Djokovic missed out on a calendar Grand Slam in New York before being banished from Australia, and despite drawing level with Rafael Nadal and Roger Federer on 20 grand slams with his Centre Court triumph, he now finds himself two adrift of the Spaniard again.

Barty, meanwhile, has left her own party. The then world number one stunned the tennis world by retiring in March, having added the Australian Open she so craved to her trophy cabinet.

Djokovic and Iga Swiatek head into Wimbledon, which begins on Monday, as the top seeds.

Stats Perform has used Opta facts to consider what the men's and women's singles might deliver.

KING ROGER'S REIGN IS OVER, BUT DJOKOVIC AND NADAL KEEP GOING STRONG

There will come a time when the Wimbledon favourite is not one of the 'Big Three'. That time is not now.

Djokovic is the man most likely, as he targets his fourth straight Wimbledon title and seventh overall; since 2011, when he beat Nadal in the final, the Serbian has only been absent from the trophy match three times (in 2012, 2016 and 2017).

His winning run of 21 matches at Wimbledon is the fifth-longest in the men's singles. Bjorn Borg holds the record (41 between 1976 and 1981).

The last player other than Djokovic, Nadal, Federer and Andy Murray to win the Wimbledon men's title was Lleyton Hewitt in 2002. Federer is absent this year and may have played his last Wimbledon.

Nadal has won Wimbledon twice, in 2008 and 2010. He won the French Open, Wimbledon and the US Open in 2010, the only season of his career when he has won three slams. This year, at the age of 36, he has the Australian and French Open trophies already locked away, potentially halfway to a calendar Grand Slam, last achieved in men's singles in 1969 by Rod Laver.

Should Nadal pull off another major coup, it would make him only the second man in the Open Era (from 1968) to win the season's first three singles slams, after Laver in 1969 and Djokovic last year.

Can the rest hope to compete?

What of Murray? Well, only Federer (19), Sampras (10), Laver and Jimmy Connors (both nine) have won more ATP titles on grass than the Scot in the Open Era. If he recovers from an abdominal strain, he has a shot at reaching the second week. He will of course have the full backing of the Wimbledon crowd.

Last year's runner-up Matteo Berrettini is fancied more than Nadal by many, having won Stuttgart and Queen's Club titles in the build-up.

There has not been an American men's singles champion since 2000, and although the United States has six players seeded, more than any other nation, it seems a safe enough assumption we will be saying a similar thing again in 12 months' time.

Third seed Casper Ruud has never won a singles match at Wimbledon, while fourth seed Stefanos Tsitsipas has not had a win since reaching the fourth round in 2018. Daniil Medvedev, the world number one, cannot compete at The All England Club after their contentious decision to ban Russian and Belarusian players due to Russia's invasion of Ukraine.

IF SERENA CAN'T CHALLENGE SWIATEK, WHO CAN?

From the jaws of retirement, Serena Williams is back. Silence from the 40-year-old about her intentions had become almost deafening, and yet here she is, back at Wimbledon on a wildcard, hoping to rekindle the old magic.

Because she has pushed back against the doubters for over two decades now, you have to take this seriously. Her haul of 23 grand slams is one short of Margaret Court's all-time record and Williams would dearly love to at least match it.

Three years ago, Williams became the oldest player to reach Wimbledon's women's singles final when she lost to Simona Halep. Six years ago, she was the oldest champion when she beat Angelique Kerber.

Only four women in the draw this year besides Williams have been champion before: Petra Kvitova (in 2011 and 2014), Garbine Muguruza (in 2017), Kerber (in 2018) and Halep (in 2019).

World number one Iga Swiatek starts as favourite. Junior Wimbledon champion four years ago, she has scooped two women's French Open titles since then and is on a 35-match winning streak.

After triumphing at Roland Garros in early June, Swiatek will hope to become the first woman since Kerber in 2016 (Australian Open and US Open) to win two singles slams in the same season.

The only competitive warm-up for Williams came in two doubles matches at Eastbourne, having not played since sustaining a hamstring injury at Wimbledon last year. The seven-time champion might consider it a challenge that there has never been an unseeded Wimbledon women's singles finalist during the Open Era.

The women's top two seeds have not met in the final since Serena faced her sister Venus in the 2002 title match, so don't hold your breath for a Swiatek versus Anett Kontaveit showpiece on July 9.

Could Gauff be best of the rest?

Coco Gauff made a breakthrough with her run to the French Open final. Although she was blown away by Swiatek, for the 18-year-old American it was another mark of progress. Gauff reached the fourth round in Wimbledon in 2019 (lost to Halep) and 2021 (lost to Kerber).

Fitness is likely to be the key factor in how US Open champion Emma Raducanu fares at her home grand slam, given her injury problems. Raducanu reached the fourth round on a wildcard last year and the 19-year-old will attempt to become the first British woman to reach that stage in back-to-back seasons since Jo Durie (1984, 1985).

Ons Jabeur, meanwhile, should not be discounted. The world number three reached the quarter-finals at SW19 last year and heads to Wimbledon having won on grass at the Berlin Open, albeit Belinda Bencic had retired hurt in the final.

The likes of Gauff, Raducanu and 21-year-old Swiatek will attempt to become the youngest woman to lift the trophy since 17-year-old Maria Sharapova triumphed in 2004.

A first-round exit for Swiatek would leave the event wide open, but don't count on it. In the Open Era, only three times has the top-seeded woman lost in round one: Steffi Graf in 1994 and Martina Hingis in 1999 and 2001.

Coco Gauff is relaxed and full of confidence heading into Wimbledon, three years after bursting onto the scene at the All England Club.

Gauff made history as a 15-year-old at Wimbledon in 2019, when she became the youngest player to reach the main draw in the Open Era.

The American stunned five-time Wimbledon champion Venus Williams in straight sets in her main draw debut, and reached the fourth round, where she was defeated by eventual champion Simona Halep.

She enters this year's tournament brimming with confidence after reaching her first Grand Slam singles final earlier in June, having lost to Iga Swiatek in a French Open showdown.

"Honestly, I feel like I'm a lot more relaxed than when I was considered the sensation or whatever," Gauff told a news conference.

"I mean, I did well, wasn't expecting to, but it felt like everybody wanted the results to happen now, now, now. I feel like I learned so much not to put pressure on now, now, now.

"This time around, even though I’m considered a favourite, I don't feel like it as much as I did when I was 15 or even 16."

A year ago at Wimbledon, Gauff again reached the fourth round, where she was ousted by Angelique Kerber, but she enters play this time around with her highest world ranking at number 12 after an outstanding performance at Roland Garros, where she reached the final of both the singles and doubles.

"Definitely a lot of positives to take from it, that I can play two weeks of high, competitive tennis in two events," Gauff explained.

"I would have never thought I would have made the final of both events. I learned a lot from that final. I’m going to take what I learned to here. Hopefully I go far.

"But it was definitely the experience of a lifetime, and hopefully I can recreate it."

Gauff followed up her run in Paris with another encouraging showing in a grass-court warm-up at the Berlin Open, where the 18-year-old lost to Ons Jabeur in the semi-finals.

It marked another milestone for Gauff, who had previously never advanced to a quarter-final on grass.

Ons Jabeur kept Coco Gauff waiting for a top 10 debut as the Tunisian battled past her teenage opponent to reach the Berlin Open final.

Gauff would have secured a career-high ranking on the WTA list if she had won Saturday's semi-final, but top seed Jabeur took it 7-6 (7-4) 6-2 to earn a shot at Belinda Bencic in the title match.

Only world number one Iga Swiatek has won more matches on the WTA Tour than fourth-ranked Jabeur this year, who collected a 29th win as she overcame a 3-1 career head-to-head deficit against Gauff to earn the victory.

Gauff, at 18 years and 98 days, would have become the youngest American to reach a grass-court singles final on tour since Andrea Jaeger was runner-up to Martina Navratilova at Wimbledon in 1983.

It was not to be her day though, Jabeur breaking serve for the fourth time in the match to seal victory, encouraged by a large and vocal Tunisian following.

Reflecting on the match, Jabeur said: "When you play Coco you have to have all the shots. She's a talented player; she's very tough to beat. You can see I've lost already three times against her.

"Sometimes she takes it, sometimes I take it, and it was a great match for both of us."

This is just the second WTA tournament where 27-year-old Jabeur has been a top seed.

"I've tried to act like a number one seed on and off the court, and it's a good pressure," she added. "I'm trying to handle it very well and with the support of our Tunisian people here it's great."

Olympic gold medallist Bencic had earlier claimed an impressive 6-7 (6-8) 6-4 6-4 win over Greek second seed Maria Sakkari in the first semi-final.

Jabeur was bettered by Bencic in a hard-fought Charleston final in April, but is determined to secure a different outcome this time.

"I'm definitely going for the final revenge because we played each other at Charleston, and it was a very, very tough match," Jabeur said. "I hope she's tired from today's match."

Rain meant there was no play at the Birmingham Classic on Saturday, with the semi-finals set back to Sunday.

Beatriz Haddad Maia will face 2019 Wimbledon champion Simona Halep, while Zhang Shuai tackles Sorana Cirstea.
