Caroline Garcia

Italian Giorgi battled to take the first set but was pegged back by the home favourite before her game collapsed in a 5-7 6-4 6-0 defeat.

Dominant on serve in the opening set, Giorgi failed to take either of two break points at 3-2 up in the second set. She then won only one point in three consecutive games to allow Garcia to level.

The world number 29 earned just two points on serve in a one-sided decider as Garcia set up a last-16 clash with another Italian, Martina Trevisan.

Earlier, Russian Vera Zvonareva was comfortably beaten by seventh seed Alison van Uytvanck, who could await Garcia in the quarter-finals.

Zhang Shuai beat Kristina Mladenovic 7-6 (7-3) 7-5 to secure a match with Arantxa Rus, who defeated Danka Kovinic for the loss of just two games.

The top-ranked remaining player in the draw, world number 30 Sorana Cirstea, sealed a round-of-16 showdown with Stefanie Voegele after a comfortable 6-3 6-1 defeat of Mariam Bolkvadze.

Gracheva, ranked 88th in the world, needed two hours and 31 minutes to get past Linette 6-3 4-6 6-4 in Austin.

The Pole had led 2-0 in the third set before Gracheva hit back with three breaks in the final frame to run away with a shock victory.

Linette's early exit followed that of second seed Zhang Shuai who withdrew from the tournament on Tuesday due to illness.

Fifth seed Sloane Stephens had no such troubles, progressing into the second round with a 6-3 6-3 victory over Taylor Townsend.

Fourth seed Danielle Collins won 6-7 (7-9) 6-2 6-4 over Magdalena Frech in two hours and 32 minutes, while third seed Anastasia Potapova eased past Elizabeth Mandlik 6-2 6-0.

Top seed Caroline Garcia cruised into the second round at the Monterrey Open in Mexico on Tuesday, winning 6-3 6-4 over Slovenia's Kaja Juvan.

Third seed Donna Vekic survived an early scare to win by virtue of a walkover at 2-6 5-0 against Lesia Tsurenko who retired for the second straight tournament.

Fourth seed Elise Mertens was too strong for Diana Shnaider 6-0 6-4, while seeds Mayar Sherif and Elisabetta Cocciaretto also progressed.

Sixth seed Katerina Siniakova, who made last week's Mexican Open semi-finals, was eliminated after a controversial call on match point in a third-set tie-break, losing to Kamilla Rakhimova 7-6 (8-6) 2-6 7-6 (7-5).

Last week's Mexican Open champion Camila Giorgi was knocked out 6-4 7-5 by Romanian qualifier Elena-Gabriela Ruse.

The 21-year-old broke serve five times on her way to a 6-2 6-3 victory over Spain's Cristina Bucsa in an hour and five minutes, booking a quarter-final place.

Yastremska fled war-ravaged Ukraine last week, along with sister Ivanna, escaping through Romania but leaving their parents behind in Odessa after Russia's invasion began.

The three-time WTA tournament winner has spoken of the decision by her mother to stay with her father, and how that left the sisters tearful and agonising over when the family might be reunited.

Yastremska began her campaign in Lyon with a gruelling three-set win over Ana Bogdan and followed up impressively by sweeping aside Bucsa.

"Today, definitely it was a little bit easier. With my emotions, I could keep them under control, so I'm very happy with that," Yastremska said in an on-court interview, broadcast on Amazon Prime.

"I tried yesterday to recover myself as fast as possible to prepare for my match today. Still, I was very nervous because I wanted to win the match for my country.

"This tournament is very emotional for me, but I'm very happy with the win today. To be honest I'm very happy that I'm here, that I'm in a safe place with my sister."

The former world number 21, now down at 140 in the WTA rankings, was joined in the last eight by Zhang Shuai of China and France's Caroline Garcia.

Also going through to the quarter-finals on Thursday was Vitalia Diatchenko, a Russian playing under a neutral flag this week. She beat Swiss third seed Viktorija Golubic in three sets.

Osaka, the 2018 champion in New York, was pushed before getting past Ukrainian teenager Marta Kostyuk.

The top half of the women's draw is packed with seeds as Kerber and Kvitova were among those advancing at Flushing Meadows.

Petra Martic, the eighth seed, also booked her spot in the fourth round.

OSAKA GETS THROUGH TEST

Osaka, the fourth seed and two-time grand slam winner, battled past Kostyuk 6-3 6-7 (4-7) 6-2.

The Japanese star had 30 winners and 38 unforced errors before advancing in two hours, 33 minutes.

Osaka's left leg was again heavily strapped, but the 22-year-old insisted she was feeling fine.

"I felt like I was moving well," she said. "It could be better, but I think for a three-set match, the amount of movement that I did, and the fact that I felt like I could have kept going if I really needed to is definitely a good sign."

Awaiting Osaka in the fourth round is Anett Kontaveit after the Estonian 14th seed powered past Magda Linette 6-3 6-2.

KERBER, KVITOVA KEEP WINNING

For the first time since winning the tournament in 2016, Kerber is into the fourth round.

The German 17th seed was too good for Ann Li 6-3 6-4 in just 76 minutes.

"I came here and I have no idea where I am, to be honest. Still, I mean, I had three good matches, also close matches. Every match was a little bit different," Kerber said.

"But now the second week and the fourth round, I mean, you know, I'm not thinking too much ahead. It's more like I have a day off tomorrow. Then I have the next match. This is more my focus.

"I'm really trying to staying here as well in the bubble, also mentally and getting ready for the next match."

Up next for Kerber is Jennifer Brady, the American 28th seed having recorded a 6-3 6-3 win over Caroline Garcia.

A two-time US Open quarter-finalist, Kvitova advanced after a 6-4 6-3 victory over Jessica Pegula on Arthur Ashe Stadium.

MARTIC CONTINUES RUN

A quarter-finalist at the French Open last year, Martic matched a career best thanks to a 6-3 6-3 win over Varvara Gracheva.

The Croatian is into the fourth round in New York for just the second time, having also achieved the feat last year.

She will meet Yulia Putintseva, who overcame Aliaksandra Sasnovich 3-6 6-2 6-1.

A former finalist in New York, Pliskova bowed out in the second round at Flushing Meadows.

It came on what was a mixed day for the seeds in the women's draw at the grand slam, which is being played behind closed doors due to the coronavirus pandemic.

But the likes of Osaka, Kvitova and Angelique Kerber progressed without dropping a set.

PLISKOVA CRASHES OUT

Runner-up in 2016, Pliskova fell to Caroline Garcia 6-1 7-6 (7-2) after one hour, 33 minutes.

Garcia, who reached fourth in the world rankings in 2018, produced 30 winners and just 17 unforced errors in an impressive win.

"In the second set I had set point. That was definitely one ball I could make. I had second serve on my forehand," Pliskova said.

"Maybe I should just play rally. I tried to go for it. It was a little bit windy on the court. I think she played amazing set and a half. Of course, I got my chances later in the second set. I didn't play good, so that's it."

Garcia will next face 28th seed Jennifer Brady, who thrashed CiCi Bellis 6-1 6-2 in just 51 minutes.

OSAKA, KVITOVA AND KERBER MOVE THROUGH

Osaka, the 2018 champion and fourth seed, was far too strong for Camila Giorgi in a 6-1 6-2 victory.

The Japanese two-time grand slam winner capitalised on a wayward display from Giorgi, who finished with 24 unforced errors.

"Just playing Camila, I haven't played her in a while, but I know that she goes for things," Osaka said. "For me it's really helpful mentally just because I know she's capable of finishing points.

"It gives me motive to play better, so she's not able to hit winners."

Awaiting Osaka in the third round is Marta Kostyuk after the Ukrainian teenager eliminated 31st seed Anastasija Sevastova.

Kvitova, the Czech sixth seed, was tested before getting past Kateryna Kozlova 7-6 (7-3) 6-2.

Meanwhile, 17th seed Kerber beat Anna-Lena Friedsam 6-3 7-6 (8-6) in an all-German affair.

MLADENOVIC IN EPIC COLLAPSE

Kristina Mladenovic looked set for an easy passage into the third round against Russian Varvara Gracheva.

Mladenovic led 6-1 5-1 before an incredible collapse saw her beaten in three sets.

Gracheva saved four match points in the second set before claiming a 1-6 7-6 (7-2) 6-0 victory.

Mladenovic was one of seven seeds to fall on Wednesday, with Dayana Yastremska, Alison Riske, Elena Rybakina and Marketa Vondrousova joining Pliskova and Sevastova in exiting.

In a closely contested battle, Gauff was just a little too good, winning 52 per cent (91-of-176) of the total points, while creating 11 break point opportunities compared to nine for Zhang.

It continues a terrific run of form for the 18-year-old, who will break into the top 10 of the world rankings for the first time when it updates this coming week.

Speaking to the media after advancing to the quarter-finals, Gauff compared the atmosphere inside Arthur Ashe Stadium – where she has played every match this tournament – to an NBA game.

"It's way different [to a normal tennis crowd]," she said. "On the 6-5 changeover, people were saying 'let's go, Coco' – I was literally trying not to smile. 

"I was, like, I've got to stay in the zone. Inside I was trying my hardest not to smile. This is a surreal moment for me – on Arthur Ashe Stadium and people are chanting my game. I feel like I'm at an NBA game.

"That's a special thing about tennis. When you go to a football game or an NBA game, people are chanting the team's name. That's great as a player. 

"For you to have the whole crowd chanting your name specifically is something I won't take for granted."

When asked if the incredible attention she has received this week has been a distraction, she said it only helps her in the heat of the contest.

"I think it depends on the player – for me though, I just feed off of it," she said. "I think it helps me more. 

"I mean, for some players, they prefer a more chill, relaxed environment. For me, if anyone has seen me play, I like to get pumped up. The New York crowd seems to like it too."

A meeting with the in-form Caroline Garcia is scheduled for the quarter-final, and she said it is no secret that she is one of the hottest players on tour right now.

"I think she's playing the best tennis she's played in a long time," she said. "It's going to be a challenge. 

"When you play these players that are hot, I think it's more of a mental challenge. You just gotta accept she's going to hit some great shots, because I know she will.

"I think my mentality has been great. I played I feel like two similar opponents, Maddie Keys, who can hit some unbelievable shots from the wings. Same with Shuai today. She was hitting some great shots. 

"I think I was doing a good job of accepting it, clapping my hands, moving on to the next point. I think I'm going to have to do that for the next match."

Gauff and Garcia have played twice before, with the American winning both matches against the Frenchwoman.

In her toughest matchup of the tournament so far, the Frenchwoman was emphatic as she comfortably handled rising star Coco Gauff 6-3 6-4 in Tuesday's quarter-final.

Garcia, 28, shot onto the international stage when she was impressive before ultimately losing to Maria Sharapova back in 2011 when she was just 17 years old.

At the time, Andy Murray tweeted that she would be a future world number one, and she appeared to be on that path when she peaked at fourth in the world in 2018, before a couple of rough years had her residing outside of the top 50.

Now in career-best form, Garcia has 31 wins from her past 35 matches, including 13 wins in a row and six straight-sets victories on the trot.

Speaking to the media after her quarter-final triumph, Garcia said the long, winding journey to this point has only given her valuable experience.

"When it was 2011 after the Sharapova match, it was a lot of pressure coming from actually nowhere," she said. "I was 150, 200 in the world, 17 years old. My game was not ready. 

"I was not able to play that consistent, this kind of level. The weeks after I went back trying to play the same level, but it was not possible for me.

"It was tough because people were expecting a lot. But the game, I was not ready for anything like that. It took me some time to come step-by-step to the top.

"End of 2017, 2018 was a great year, a lot of success. Yeah, I made some mistakes. We made some mistakes. I really hope and think we can learn from it.

"Now, it's a new year, trying to learn from every challenge. I think I've grown up a lot with all the challenges on and off court. Off court, it's very important to manage all of it."

Touching on what has clicked in her recent run, Garcia said she has figured out what works for her, which has simplified everything.

"I'm just trying to focus on my game, on what I like to do, and how is the best way for me to play tennis," she said.

"The path is very clear right now, which direction I have to go, under stress, under pressure. I'm just trying to follow this path. That's how we prepare with the team. We try to do the best we can in this direction.

"It was not that clear in the past. It was not that clear. I mean, I've always been very aggressive. I always try to put the pressure on the other one to be on the court.

"But I was younger… and now [I can] accept that it's actually the only way for me. So if I want to do good, I have to go that way. Yeah, now it's way more clear.

"Obviously with a lot of wins, I'm having fun playing. I can see so many things I can still improve, so it's a great challenge for our team."

Garcia will play world number five Ons Jabeur in the semi-final, with Jabeur winning both of their two previous matches since turning professional.

On Sunday, Garcia moved through to the quarter-finals by beating Alison Riske-Amritraj 6-4 6-1 on Louis Armstrong Stadium.

She has won four matches without dropping a set in the first week of the grand slam in Queens, New York, but that is just the continuation of a sensational hot streak.

Garcia, now 28, has won 30 of her last 34 matches, landing titles in Bad Homburg, Warsaw and Cincinnati along the way.

At the 2011 French Open, ATP superstar Andy Murray was so taken by the 17-year-old Garcia's performance against Maria Sharapova that he predicted: "The girl Sharapova is playing is going to be number one in the world one day."

Perhaps Murray will turn out to be right after all, with that forecast having long hung over Garcia, as well intended as it was at the time.

She reached a peak of number four in 2018 but was down at 79th on the WTA list in late May of this year.

Now she sits 17th and will keep climbing after reaching the last eight at the US Open for the first time.

On a 12-match winning streak at present, Garcia said after sinking the hopes of American Riske-Amritraj: "I'm so excited to be in the quarters of the US Open. It's been a great couple of weeks for me."

She came through qualifying to win the Western and Southern Open in Cincinnati, beating Petra Kvitova in that final after felling three seeds along the way.

Recent wins over Iga Swiatek in Poland and Emma Raducanu at Wimbledon, beating home favourites, have showed Garcia is suddenly fearless.

"I'm really trying to play aggressive, go for my shots, even when I'm tight or even when I don't feel it," she said.

"It's how I improved so much in the last couple of months and I really enjoy playing like that, moving forward, and I'm having fun."

Garcia was not at her most fluent in the first set of Sunday's fourth-round match but improved and finished the contest having hit 30 winners.

She has only played one grand slam quarter-final before, losing to Karolina Pliskova at that stage in the 2017 French Open.

Suddenly, though, she is playing top-five standard tennis again, and Garcia will take some stopping.

"I want to enjoy every single win I have," Garcia said in an on-court interview.

"When you don't have them, you miss them, so I want to enjoy this one and recover and get ready for the big match in the quarter.

"I'm really having fun here in the US. I got a lot of confidence from Cincinnati, really enjoy the good energy in New York."

Cornet, who defeated reigning champion Emma Raducanu in straight sets to begin her campaign, was terrific with her return game early on, winning 54 per cent of the points off Siniakova's serve in the opening set.

Three double faults for Cornet and the inability to win a single point off her second serve led to a quick second frame for Siniakova, but she steadied in the decider, becoming the first Frenchwoman to win her opening two rounds of each grand slam in a season since Caroline Garcia in 2017.

Cornet has now won five of her past six matches and should be considered a threat given her victory over world number one Iga Swiatek at Wimbledon in July.

She will play the winner between Danielle Collins and Cristina Bucsa in her next match.

Jabeur defeated Caroline Garcia in Thursday's semi-final, needing only 67 minutes to storm through 6-1 6-3 to reach her second consecutive grand slam decider.

Her loss to Elena Rybakina in July's Wimbledon final was her first time making it to the final match of a grand slam, but after winning the first set in that match, Jabeur fell apart, losing the next two sets 6-2 6-2.

Speaking to the media after earning another chance at a major title, the 28-year-old said she is more focused this time around after being almost starstruck at Wimbledon.

"It feels more real [this time], to be honest with you," she said. "At Wimbledon I was kind of just living the dream, and I couldn't believe it. 

"Even just after the match [today], I was just going to do my thing, not realising it was an amazing achievement already… I hope I'm getting used to it.

"I'm just happy about the fact that I backed up the results in Wimbledon and people are not really surprised I'm in the finals… now maybe I'll know what to do in the final."

Touching on what lessons she learned from that experience, she said she feels she will not be overwhelmed if she is faced with the prospect of being one set away from a grand slam.

"From Wimbledon, just, you know, a lot of emotions," she said. "Just going to that final was really tough for me, especially the second set. I think I handled things very well coming to the court and playing the first set.

"But then I feel like this final, I'm going full in, I'm going for everything. Definitely also learning from Rome's final [lost to Iga Swiatek], Madrid [defeated Jessica Pegula] and other ones.

"I feel very positive about this one. You know, the most important thing is not to regret, because I'm going to give it all on this one. Even if this one is not going to happen, I'm very sure that another one will come."

When asked if her preparation has changed at all from Wimbledon to now, she said minor tweaks to her mindset are the key.

"Will I do things differently? Probably yes," she said. "Some things maybe in the match, for sure, but I think I'm definitely going to think about [Wimbledon] and think about how I played, and the emotions and my focus more than tactically.

"At certain times I think I played not the right way in the final, so it didn't help me much. But always, it's always nice to stick with the same plan. 

"You know, when you get stressed sometimes, you just don't know how to think. I think that I'm going to use [that experience] very well… I think it's going to be great."

Jabeur, the world number five, was dominant in the opening set, winning 75 per cent of her service points and 61 per cent of her return points, allowing no break point opportunities while taking all three of her own chances to break.

She wrapped up the first set in 24 minutes, and after an even start to the second frame, Jabeur capitalised on her first and only break point chance to grab the decisive lead.

Tunisia's best ever tennis export served things out in style, finishing the match without Garcia ever seeing a break point chance.

It ends a remarkable run for Garcia, who entered the contest on a 13-match winning streak, with 31 wins from her past 35. After dominating Coco Gauff in the quarter-finals, Garcia became the betting favourite to win the tournament.

For Jabeur, it continues a career-best season after reaching her first ever grand slam final at Wimbledon, and her ranking will be bumped up to number two in the world when it next updates.

She will play the winner between Iga Swiatek and Aryna Sabalenka in the decider.

Data Slam: Jabeur makes more history for African tennis

Jabeur is the first African, Arab or Tunisian woman to ever reach the US Open final, after also accomplishing that feat at Wimbledon.

Through six matches at this tournament, she has only lost one set – in the third round against American Shelby Rogers.

WINNERS/UNFORCED ERRORS

Jabeur – 21/15

Garcia – 12/23

ACES/DOUBLE FAULTS

Jabeur – 8/2

Garcia – 2/0

BREAK POINTS WON

Jabeur – 4/4

Garcia – 0/0

Vekic, 26, has now won 14 of her past 16 matches dating back to New Year's Eve, and she dropped only two sets through her five matches in Mexico this week. She also made the 2023 Australian Open quarter-finals, losing to eventual winner Aryna Sabalenka.

The Croatian grabbed the early break to control the first frame, and when serving for the set, Vekic showed grit to fight back from a 40-0 deficit and save three break points en route to securing the opener.

She kept her momentum rolling into the second, breaking and consolidating to jump ahead 2-0, but the response from France's Garcia showed why she was the WTA Finals champion last season, rattling off five games in a row.

But Vekic showed no signs of slowing down, and Garcia was forced to save eight break points to keep the third set level, before the dam finally broke at 6-5 to prevent a tiebreaker.

It was the fourth title of Vekic's career, but only her second since 2017, having snapped a four-year drought at the 2021 Courmayeur Ladies Open.

The 30-year-old Watson lost in qualifying for the recent Australian Open, having made the singles main draw for 11 consecutive years, but she is already beginning to make up for the Melbourne disappointment.

Kazakh Putintseva is ranked 44th in the world, while Watson has slipped to 160th, but the Guernsey native has been as high as 38th in her career and won four titles on the WTA Tour.

She showed there is still a hunger to succeed, edging a tight contest 5-7 6-4 7-5 (7-5) to make Putintseva the biggest early casualty.

Top seed Bianca Andreescu had no such trouble against Watson's compatriot Harriet Dart, as the Canadian went through a 6-3 6-4 winner.

Czech 17-year-old Linda Fruhvirtova, seeded eighth and at a career-high 51st in the WTA rankings, overwhelmed American veteran Bethanie Mattek-Sands 6-3 6-1.

Fellow seeds Marta Kostyuk, Anna Kalinskaya and Tatjana Maria also came through their opening tests at the tournament in Hua Hin.

At the Lyon Open, French top seed Caroline Garcia fended off Czech Tereza Martincova 6-4 7-6 (7-4) in round one, delighting a home crowd.

Champion at the WTA Finals at the end of last season, Garcia surprisingly lost in round four of the Australian Open to unseeded Pole Magda Linette, who went on a fairy tale run to the semi-finals.

Garcia said of Tuesday's win over Martincova: "It was a tough match. She's a great player. She's already played great battles against top players, and it's a first round, so you really never know what is going to happen."

Second seed Zhang Shuai beat American Madison Brengle 6-3 6-2, but eighth seed Anna Blinkova bowed out, retiring when 4-0 behind in a deciding set against fellow Russian Erika Andreeva.

A dominant showing from Garcia saw her hammer 24 winners, win 71 per cent of points played behind her first serve and win 15 of 18 points when she came to the net – with Raducanu unable to muster a response despite being encouraged by the Centre Court crowd.

Doubts were present ahead of the tournament as to whether the 19-year-old would feature given injury issues, which limited her to only seven games before retiring in her only match at the British grass-court events leading up to the event at SW19.

The world number 11 had the hopes of a nation on her shoulders heading into the campaign but, speaking after her straight-sets defeat to Garcia, downplayed the result.

"Obviously it's tough to lose any match. But it's okay because coming into this I didn't really have any expectations of myself," she told a news conference.

Defeat for Raducanu means she has not won successive matches at a grand slam since her victory at the US Open last year, having also fallen at the second-round stage in both the Australian and French Open.

However, she brushed off any suggestion that she's weighed down by pressure, stating: "I am 19 years old. Yes, I have had attention. But I'm a slam champion, so no one's going to take that away from me. If anything, the pressure is on those who haven't done that."

Raducanu had a slow start to the game, with Garcia securing two breaks in the opening set and causing the British number one trouble with her aggressive approach, taking a 6-3 win.

A brilliant rally in game five of the second set again was finished off by Garcia to help her on her way to another break and, despite a swift response from Raducanu for only her second break of the game, took another to take command of the match.

The world no. 55 then broke Raducanu for the third time in a row to secure her seventh consecutive grass victory – which was her first at Wimbledon since 2014 – leading to a memorable first visit to Centre Court.

"I really enjoyed playing on Centre Court, it was my first time and very special," she said after the match.

"You win a couple of matches in a row and I won a title in Germany but you have to start all over again.

"That is what is nice about tennis - we all start from zero and we have to go for it."

Garcia will play Shuai Zhang in the third round. Zhang defeated Ukrainian Marta Kostyuk in straight sets earlier on Wednesday.

Iga Swiatek heads the list of contenders to carry off the trophy in Fort Worth, Texas, having enjoyed a spectacular season.

Ascendant Americans Jessica Pegula and Coco Gauff will be chasing a home victory, while Tunisia's Ons Jabeur has reached finals at Wimbledon and the US Open so loves the big occasion.

Ahead of the tournament getting under way on Monday, Stats Perform has taken a look at the eight-player field.

Swiatek still the player to beat

With no past winner in the line-up, there is every reason to look to the world number one, Swiatek, as favourite.

The 21-year-old Polish player has eight titles this year, lifting trophies at Doha, Indian Wells, Miami, Stuttgart, Rome, the French Open, the US Open and San Diego.

Indeed, she is the only grand slam singles winner in the draw, with Ash Barty having retired and Elena Rybakina absent after no ranking or race points were awarded at Wimbledon, where she was a surprise champion.

Rybakina's absence calls into question the meritocracy of this year's tournament, which is intended to showcase the top performers on tour, yet there can be no doubt the season's premier performer is in the draw.

French Open and US Open winner Swiatek's remarkable run of 10 straight-sets victories in finals (dating back to the 2020 French Open) was finally ended by Barbora Krejcikova, who sprang a shock by winning in Ostrava in early October.

But by getting back to winning ways a week later in San Diego, scrapping for a three-set victory over Donna Vekic in the title match, Swiatek produced a typically impressive response, beating Qinwen Zheng, Gauff and Pegula on her way through the draw to improve to 64-8 in her win-loss record for the year.

Here is a measure of her dominance this season: Swiatek headed the 'Race to the WTA Finals' rankings with 10,335 points, with the players in second (Jabeur) to eighth place (Daria Kasatkina) having tallies ranging between 4,555 and 2,935 points.

Is Pegula the chief rival to Swiatek?

She might not have been the player that would have sprung to mind even a month ago, but Pegula's victory at the Guadalajara Open this month was an eye-opener.

Beginning by saving match points in a thrilling three-setter against Rybakina, Pegula took down grand slam winners Bianca Andreescu, Sloane Stephens and Victoria Azarenka before swatting aside Maria Sakkari in the final.

Pegula has reached quarter-finals at the Australian, French and US Opens in 2022, and she has a tour-high 39 wins in WTA 1000 events since the beginning of last year.

She is up to third in the WTA rankings, one ahead of Coco Gauff, with the United States now having two women in the top five for the first time since October 2010, when Serena Williams was number two and sister Venus sat fourth.

As Pegula said after the Guadalajara final: "I'm definitely a very ambitious person. A little bit of a perfectionist, as well. I don't think you could win if you weren't ambitious, especially at this level.

"I feel like it's going to give me more motivation going forward knowing I can win these big titles. I think it will give me a lot of confidence ending the year, going into next year."

These are spirited words. She heads into the tournament with a 0-4 record against Swiatek in 2022, however.

Who's in, who's out, what's it all about?

As well as Swiatek and Pegula, the field for the eight-day tournament includes Caroline Garcia, Aryna Sabalenka and Sakkari, who have all featured at the WTA Finals in the past.

Four players make their debuts, including Pegula, who is joined as a newcomer by Jabeur, Gauff and Daria Kasatkina.

Gauff, 18, has become the 14th player aged under 19 to reach the WTA top five since the rankings were introduced in 1975.

She would not be the youngest WTA Finals champion, were she to lift the title, as Monica Seles has a tight grip on that record, having triumphed at the age of 16 years and 11 months at the 1990 edition.

Last year's champion Garbine Muguruza is absent. The Spaniard was expected by many to push on and enjoy a stellar 2022 season, but it did not play out that way, with the former French Open and Wimbledon winner sliding to 57th in the world rankings after a dismal campaign.

It goes to show that whoever prevails in Fort Worth, we should be cautious about treating the outcome as an indication of what to expect in the new year.
