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." 

There seems to be no escaping the number 23 for Serena Williams as she prepares for an emotional final grand slam at the US Open.

It is 23 years since the legendary American won her first major singles title at Flushing Meadows, where she was also crowned doubles champion back in 1999.

Williams has gone on to win an astonishing 23 grand slam singles titles and 14 major doubles titles in an incredible career that is about to come to an end in New York.

One of the all-time greats turns 42 next month and although she is unlikely to bow out by claiming an elusive 24th major singles title in her home major, she is sure to be given a spine-tingling farewell.

Novak Djokovic's absence due to not being vaccinated against COVID-19 has been the big talking point in the men's singles, with Rafael Nadal getting an opportunity to extend his record tally of major successes.

Stats Perform picks out the standout numbers to preview the final major of the year as Emma Raducanu and Daniil Medvedev prepare to defend their titles.

Serena's incredible longevity

Such is the remarkable longevity of Williams' career, defending champion Raducanu and world number one Iga Swiatek were not even born when she won her first major.

Wimbledon champion Elena Rybakina was only a few months old when the iconic Saginaw native beat Martina Hingis in the 1999 US Open final for the first of so many major titles.

Only Chris Evert can boast as many US Open titles as Williams' tally of six in the Open Era, while she has played in a record 10 finals at Flushing Meadows.

The retiring veteran has 106 victories in her home major, a record in the Open Era, and only Martina Navratilova has recorded more wins in a single major - with 120 at Wimbledon.

Williams will be making her 21st main-draw appearance at the US Open, with only her older sister, Venus, bettering that figure in the Open Era as she prepares for her 23rd.

Long-awaited New York return for Nadal 

Nadal has not played at Flushing Meadows since he was crowned champion for a fourth time three years ago, having missed the 2020 tournament amid the coronavirus pandemic and not played last year due to a foot injury.

The Spanish great's hopes of completing a first calendar Grand Slam were ended by an abdominal injury that resulted in his withdrawal from Wimbledon ahead of a scheduled semi-final against Nick Kyrgios.

He could make it three major titles out of four this year in New York, though, where he will be bidding to take his haul of grand slam titles to 23 and move two clear of the absent Djokovic once again.

If Nadal lifts the trophy on Arthur Ashe Stadium, it would give him a record-equalling fifth US Open men's singles title - matching the haul of Jimmy Connors, Pete Sampras and Roger Federer.

Only Bjorn Borg (89.2 per cent) has a higher winning ratio in grand slam tournaments during the Open Era than Nadal's 88.3 per cent among players with at least 100 victories to their name, 

Another record in women's singles?

Teenage Brit Raducanu made history when she became the first qualifier to win a major title last year, beating Leylah Fernandez in the final.

Swiatek has dominated the women's game for much of this year, the highlight being her second French Open triumph.

With the retired Ash Barty, Swiatek and Rybakina taking the singles titles in 2022, there could be four different gram slam champions for a fifth consecutive season - excluding 2020 - and that would be the longest such streak in the Open Era.

Alcaraz to make major breakthrough?

While Nadal will be the Spaniard with the largest burden of expectation on his shoulders, Carlos Alcaraz should be a big threat in New York.

The 19-year-old could become the fifth player in the Open Era to reach at least the quarter-finals in his first two appearances at Flushing Meadows after Ken Rosewall, Arthur Ashe, John Newcombe and Johan Kriek.

Alcaraz has the joint-most ATP Tour titles this year with four, matching Nadal's tally.

Jannik Sinner scored his second big win over Carlos Alcaraz in July as he toppled the Spanish teenager in Sunday's Croatia Open final.

The 20-year-old Italian won his sixth career title on the ATP Tour and the first not on a hard court, beating Alcaraz 6-7 (5-7) 6-1 6-1 on clay at the Goran Ivanisevic Stadion in Umag.

Victory improved Sinner's win-loss record against Spanish players in 2022 to 8-0, and gave him a first trophy of the year. It was Alcaraz's 100th match of his career at ATP level but did not go according to his plan.

A victorious Sinner told Tennis TV: "I am obviously very happy. I come from a tough year until now. We had some unfortunate moments, but we worked every time to play better, to be a better player, to be a better person. So, I'm very happy to be finally lifting a trophy this year, but I know that I still have a lot of things to improve."

Alcaraz, who lost to Sinner's compatriot Lorenzo Musetti in last week's Hamburg European Open final, had six break points in the second game of the second set but failed to break through and fell away.

Sinner said: "He made some unforced errors, and I was very happy that I won this game. Then I returned well and raised my level a little bit, and I think I found a solution then."

Alcaraz was attempting to become the first player since Carlos Moya (2001-03) to win this title in consecutive years but fell short. He said he would have to "keep working hard to win tournaments" and hailed Sinner's "amazing level" over the week.

The 19-year-old will rise into the ATP top four for the first time on Monday but will be wary of Sinner currently having a hold over him.

Their Wimbledon match on July 3 went Sinner's way in four sets.

Small consolation for Alcaraz may have come in the fact he won a set, meaning he has done so in all 49 matches he has played this year, last losing in straight sets when he went down to Hugo Gaston at the Paris Masters last year.

Carlos Alcaraz's defence of his Croatian Open title will go down to the wire, with the Spaniard set to face Jannik Sinner in Sunday's final.

Alcaraz, the number one seed, defeated Giulio Zeppieri over three sets in Saturday's semi-final – securing his 42nd win of the year. That is the joint-most victories in 2022 on the men's tour alongside Stefanos Tsitsipas, and extends his record in Umag to 8-0.

The 7-5 4-6 6-3 win sees Alcaraz reach an ATP Tour-leading sixth final in 2022 and will lift him to fourth in the world rankings ahead of Tsitsipas – a career high for the 19-year-old.

"It's amazing to be in a final here again. I enjoy playing here in Umag and I'm really happy with the win today," Alcaraz said in an on-court interview.

Alcaraz will bring up his first century of ATP matches when he tackles Italian Sinner.

"It would be amazing in my 100th match to get the win, and of course it is amazing to be number four on Monday," Alcaraz said. "It's something great for me, but right now I am just focused on the final."

Sinner, who beat Alcaraz at Wimbledon to set up a quarter-final against Novak Djokovic, saw off compatriot Franco Agamenone 6-1 6-3 in Saturday's other semi-final.

The 20-year-old Sinner is looking for his first title of 2022, having won at Antwerp, Sofia, Washington and Melbourne last year. He has reached the quarter-finals in two of the three grand slams played so far this year.

Roberto Bautista Agut beat Albert Ramos-Vinolas in straight sets to reach the Austrian Open final, but the Spaniard must wait until Saturday to discover his opponent.

Third seed Bautista Agut proved too strong for compatriot Ramos-Vinolas as he prevailed 6-3 7-6 (7-3) in a little over two hours, despite squandering three match points.

The world number 20 now can now look forward to a first clay-court final since suffering defeat to Matteo Berrettini at the 2018 Swiss Open Gstaad.

However, the other semi-final between Yannick Hanfmann and home wild card Filip Misolic was dramatically suspended in a third-set tie-break due to heavy rain.

Misolic, who had earlier beaten Dusan Lajovic in a clash delayed from Thursday, led 1-0 in the breaker against Hanfmann when play was halted and ultimately called off until Saturday.

The final between Bautista Agut and either Hanfmann or Misolic is still scheduled to go ahead as planned shortly after that second semi-final concludes.

At the Croatian Open, defending champion Carlos Alcaraz beat Facundo Bagnis 6-0 6-4 and will now face Giulio Zeppieri, who saw off Bernabe Zapata Miralles in straight sets.

Jannik Sinner is also through to his first semi-final of 2022 after beating Roberto Carballes Baena 6-4 7-6 (7-5), with Franco Agamenone up next after overcoming Marco Cecchinato.

Carlos Alcaraz got his Croatia Open title defence off to a strong start with a straight-sets victory over Norbert Gombos on Thursday.

The Spaniard, who this week became the second-youngest player to break into the top five of the ATP rankings this century, behind only compatriot Rafael Nadal, saw off Gombos 6-2 6-3 in Umag.

Alcaraz, handed a first-round bye, will now face Facundo Bagnis in the last eight after the Argentinian beat Corentin Moutet 6-3 6-1.

Despite the straightforward nature of his victory over Gombos, the top seed was regularly tested on his own serve.

"It was a really tough match," said Alcaraz, whose triumph in Umag last year marked his first ATP Tour-level title.

"It wasn't as easy as the result seems. Norbert played a really good game and the first round of every tournament is never easy. 

"I had to get used to the conditions. It was tough for me, but at the end I found a way to play better and get the win."

Franco Agamenone also advanced to his first ATP Tour quarter-final with a 3-6 6-1 7-5 comeback over Sebastian Baez, while Marco Cecchinato upset Lorenzo Musetti 6-4 6-3.

At the Austrian Open, Dominic Thiem was eliminated in the quarter-finals of his home tournament by Yannick Hanfmann, the former world number three going down 6-4 3-6 6-4 in a rain-affected contest.

Roberto Bautista Agut prevailed 4-6 7-5 7-5 against Jiri Lehecka in a match lasting nearly three hours. A meeting with fellow Spaniard Albert Ramos-Vinolas, who defeated Pedro Martinez 6-4 6-2, is his reward.

Dominic Thiem started his bid for a second Austrian Open title with a comfortable triumph over Alexander Shevchenko.

Thiem, a 2019 winner at the tournament in his home country, prevailed 6-4 6-2 in Kitzbuhel.

He will next face compatriot Sebastian Ofner as he seeks a first title since his grand slam breakthrough at the US Open in 2020.

Ofner came from a set down to beat former world number seven Richard Gasquet 1-6 7-5 7-5.

Meanwhile, seventh seed Pedro Martinez saved six out of six break points en route to a 7-6 6-3 victory over Chilean Nicolas Jarry.

At the Croatia Open in Umag, Bernabe Zapata Miralles set up a round of 16 meeting with third seed Holger Rune by beating Croatian Dino Prizmic, who retired when facing a 6-4 3-0 deficit.

Alex Molcan is safely through to the next round after defeating Duje Ajdukovic, while French 23-year-old Corentin Moutet cruised to a straight-sets victory over sixth seed Daniel Altmaier.

Carlos Alcaraz has his sights set on climbing to the summit of the ATP rankings after becoming the youngest player to crack the top five since Rafael Nadal.

The Spaniard was downed in the Hamburg European Open final by Lorenzo Musetti over the weekend but nevertheless saw a rise in his stature to a career-high position of fifth.

In doing so, it makes the 19-year-old the second-youngest male to break into the top five this century, trailing only Nadal and bettering Novak Djokovic by a matter of months. 

"It means a lot," Alcaraz stated. "The hard work that I put in every day for reaching my dreams, [number] 1, and little by little I'm reaching my dream.

"Top five for me is pretty amazing and I will keep going to be [number] 1."

Had Alcaraz won in Hamburg, he would have risen to fourth, while other movements in the rankings include a rise to number 31 for Musetti and a return to the top 200 for Dominic Thiem, at number 199.

Lorenzo Musetti won the first ATP Tour title of his career as he defeated fellow up-and-comer Carlos Alcaraz in Sunday's Hamburg European Open final.

Top seed Alcaraz ensured he would become the youngest player in the top five of the ATP rankings since Rafael Nadal in 2005 with his semi-final victory over Alex Molcan.

But the 19-year-old paid the price for an error-strewn display on Sunday, as Musetti, 20, took the crown 6-4 6-7 (6-8) 6-4.

Alcaraz was guilty of a slow start on the clay, with four wild unforced errors helping Musetti go a break up after the very first game. Although the Spaniard instantly hit back, his opponent gobbled up his next break point to take a 4-3 lead en route to winning the set.

Musetti then took charge early on in the second to go 2-0 ahead, but Alcaraz showed admirable resolve to see off a couple of match points and level the set at 5-5, before remarkably tying the contest in a tie-break that saw three more championship points squandered.

The deciding set was evenly contested almost throughout, until Musetti broke serve to make it 6-4 and take the match on his sixth championship point as Alcaraz hit a backhand long.

On a momentous day for the Italian, his jubilation was plain to see as he spoke afterwards.

"I have no words because it was a rollercoaster until the end," Musetti said on court. "I had so many match points. Carlos was so good on the match points, [I had] so many chances.

"But I think the key of the match was to keep calm and [have] all the patience [with] myself because it was really not easy.

"Carlos was putting so much effort in the match points when he was down, so it was not easy to find the energy to come back.

"But I cannot describe what I am feeling right now. I think I am still dreaming."

On the subject of the five match points he surrendered, Musetti added: "Of course I was really upset, but I tried to not show my opponent my reaction.

"I tried to forgive [myself for] all the match points and all the points [when] I couldn't do it. I think that was the most [important] thing, even for me, because I didn't expect the win after all this rollercoaster, so I'm super happy to be here and to be the champion."

Musetti and Alcaraz could end up meeting again in the coming week in Umag, where the latter is the defending champion and top seed.

Carlos Alcaraz will play Lorenzo Musetti in the Hamburg European Open final following a straight-sets victory over Alex Molcan on Saturday.

The Spanish teenager is targeting a fifth ATP title of the year, which would move him ahead of Rafael Nadal, having already triumphed in Rio, Miami, Barcelona and Madrid.

Alcaraz is set to move into the top five of the ATP rankings for the first time after seeing off Slovakia's Molcan 7-6 (7-2) 6-1 to reach yet another championship match on his debut in Hamburg.

The top seed broke twice in the opening set but was pegged back on both occasions by Molcan, who was striving to reach a third final of 2022 after finishing as runner-up in Marrakech and Lyon.

But the 19-year-old dominated the tie-break, and found another gear to storm into the final as he made it eight successive sets won this week.

"It was tough," Alcaraz said. "Obviously, [Alex] played really well. The first set was really close; I'm really happy to be able to end the first set playing well.

"I couldn't read the drop shots from him. He was better on the drop shots today, so I was a little bit [frustrated] in the first set.

"In the second set, I think he was down a little bit; he didn't play well. I finished the match with a lot of confidence and played very well."

Standing between Alcaraz and another title is Musetti, who will appear in his maiden ATP final after he overcame Francisco Cerundolo 6-3 7-6 (7-3).

The Italian, who is set to climb into the world's top 50 for the first time, had lost six consecutive ATP Tour matches prior to this week.

But the 20-year-old continued his resurgence; ending the Bastad champion's eight-match winning streak by roaring back from 3-1 down in a second-set tie-break.

Meanwhile, Matteo Berrettini and Casper Ruud will target a third title of 2022 when they lock horns in the Swiss Open showpiece.

Berrettini - a winner in Stuttgart and Queen's before a positive COVID-19 test ruled him out of Wimbledon - registered his 12th successive victory, putting former US Open champion Dominic Thiem to the sword 6-1 6-4 in 78 minutes.

Reigning champion Ruud raced past Albert Ramos-Vinolas; winning five out of seven break points in a resounding 6-2 6-0 triumph.

Carlos Alcaraz outclassed Karen Khachanov to reach the semi-finals of the Hamburg European Open, while Matteo Berrettini will face Dominic Thiem in the last four at the Swiss Open.

Top seed Alcaraz only needed an hour and nine minutes to beat Russian Khachanov 6-0 6-2 in a clay-court masterclass on Friday.

The 19-year-old Spaniard moved a step closer to winning a fifth title this year with a dominant performance, breaking the Russian five times in a one-sided contest.

Alcaraz hit 21 winners as Khachanov was given a harsh lesson and the teenager will next face Alex Molcan, who was 2-0 up in the second set after winning the first on a tie-break when Borna Coric retired due to injury.

"I played unbelievable today, probably one of my best matches this year," Alcaraz said of his win against Khachanov. "I'm pretty happy with the performance that I'm playing in this tournament. Yesterday [a victory over Filip Krajinovic] was amazing as well.

"I'm training every day to be solid and at the same time to be aggressive. That is my game."

Francisco Cerundolo and Lorenzo Musetti will contest the other semi-final in Hamburg after beating Aslan Karatsev and Alejandro Davidovich Fokina respectively.

A rejuvenated Thiem is enjoying another hugely encouraging week and will take on Berrettini in his first semi-final of the year following a 6-4 6-3 defeat of Peruvian qualifier Juan Pablo Varillas in Gstaad.

Austrian Thiem has not played in a final since winning his only grand slam at the 2020 US Open, but he claimed his first ATP-level victory for 14 months in Bastad last week and is through to his first semi-final since May 2021 after bossing the baseline battle with Varillas.

It was not all plain sailing for Berrettini, who roared back to beat Pedro Martinez 3-6 7-6 (7-5) 6-1 after the Spaniard was in command of a second-set tie-break at 5-1, but the second seed extended his winning run to 11 matches.

Top seed Casper Ruud got the better of Jaume Munar 7-6 (7-3) 7-6 (7-4), booking a showdown with Albert Ramos-Vinolas, who came through a three-set battle with Nicolas Jarry.

Andrey Rublev crashed out of the Hamburg European Open in straight sets against Francisco Cerundolo, as top seed Carlos Alcaraz cruised past Filip Krajinovic to reach the quarter-finals.

Second seed Rublev was the latest scalp of Cerundolo's fine run of form, the Argentine making it seven consecutive wins by wrapping up a 6-4 6-2 success in just an hour and a half in Germany.

Having furthered his momentum with a second top-10 win in as many weeks, Cerundolo said: "It is the first time it has happened for me. I am playing against the top guys and I am playing well, it is unbelievable."

Cerundolo will face Aslan Karatsev in the last eight after he recovered from a set down to beat Daniel Elahi Galan 3-6 6-3 6-4.

World number six Alcaraz fared better than Rublev, registering a 7-6 (7-4) 6-3 win over Krajinovic to tee up a final-four meeting with Karen Khachanov, who beat Fabio Fognini in straight sets.

Meanwhile, a host of big names including Casper Rudd and Matteo Berrettini reached the last eight of the Swiss Open in Gstaad, as Dominic Thiem continued his revival with a win over Federico Delbonis.

Thiem reached his second quarter-final in as many weeks with an impressive 7-6 (8-6) 6-3 triumph despite letting a 5-2 lead slip in the opener, registering his first tour-level straight-sets victory since May 2021.

Having set up a meeting with Juan Pablo Varillas, the 2020 US Open champion beamed: "I have won two matches which means a lot to me right now, I really need those ranking points. Every match win is something very special."

The Austrian will be joined in the next round by first and second seeds Ruud and Berrettini, who eased past Jiri Lehecka and Richard Gasquet respectively.

Spanish duo Albert Ramos-Vinolas and Pedro Martinez also both progressed to the last eight despite dropping a set, with the latter setting up an enticing clash with Berrettini on Friday.

Carlos Alcaraz was made to come from a set down but finally overcame Nicola Kuhn in the first round of the Hamburg European Open.

The highly rated Spanish teenager eventually downed the German wildcard 3-6 6-1 7-6 (7-3).

Kuhn, ranked 259 in the world, was aggressive early on against Alcaraz, and was rewarded with the first set.

But the 19-year-old – playing as top seed in an ATP Tour event for the first time – rallied to ease through the second set, before being made to work much harder to clinch the win on a tie-break.

Alcaraz will now play Filip Krajinovic in the second round after the Serbian also won in a third-set tie-break against Sebastian Baez 6-1 4-6 7-6 (8-6).

Three seeded players crashed out on Tuesday in straight sets, with third favourite Diego Schwartzman losing against Emil Ruusuvuori 7-5 6-4, sixth seed Nikoloz Basilashvili beaten by Aslan Karatsev 6-4 6-0, and eighth seed Holger Rune going down 7-6 (10-8) 7-5 to Tallon Griekspoor. 

Fourth seed Pablo Carreno Busta eased through against Luca Nardi 6-2 6-1, while there were also wins for Fabio Fognini, who sealed his 400th career victory, as well as Daniel Elahi Galan, Borna Coric and Francisco Cerundolo.

At the Swiss Open in Gstaad, sixth seed Cristian Garin lost 6-3 6-4 to Yannick Hanfmann and seventh favourite Hugo Gaston fell to Dominic Thiem despite winning the first set, losing 1-6 6-1 7-6 (9-7).

Elsewhere, Frenchman Richard Gasquet beat Roberto Carballes Baena 7-5 6-4, while his compatriot Benoit Paire retired hurt when a set and a break down against Elias Ymer.

A tight game between Swiss pair Dominic Stricker and Marc-Andrea Huesler saw the former prevail 6-7 (2-7) 7-6 (7-2) 6-4, and an all-Spanish affair was similarly close as Jaume Munar defeated Bernabe Zapata Miralles 6-3 3-6 7-5.

There were also wins for qualifiers Juan Pablo Varillas and Nicolas Jarry against Lorenzo Sonego and Thiago Monteiro respectively.
