Emma Raducanu is hoping lessons will be learned from her first round defeat to Sofia Kenin at the US Open. 

Raducanu, who won the tournament 2021, lost in three sets 1-6 6-3 4-6 to her American opponent at Flushing Meadows, reducing her to tears after the encounter. 

After being outplayed by Kenin in the opening set, the world number 72 responded in the second to take the match the distance in New York. 

However, despite serving four of her six aces during the contest in the final set, Kenin would prove too strong to secure an all-American encounter with Jessica Pegula in the round of 64.

"I feel down, I feel sad," an emotional Raducanu said. "Obviously, this is a tournament I really want to do well in. 

"I was maybe a bit slow starting. I would have preferred to probably play, a little bit more before coming into the US Open."

"You know, I know when I have a lot of matches, just like every player, you feel really good. You feel like everything's automatic.

"So yeah, I think I can learn from it. And you know my manage my schedule slightly differently."

Data Debrief: Raducanu loses the battle of former grand slam winners

Raducanu's match against Kenin is the second R128 match at this year's US Open between two former women’s singles grand slam winners.

And while not at her best, Kenin was able to showcase her resilience that won her the Australian Open in 2020, saving six of the nine break points she faced. 

Iga Swiatek soared into the second round at Wimbledon, after beginning her latest quest for a maiden title with a straight-sets win over Sofia Kenin.

The top seed, who is aiming to progress beyond the quarter-finals at SW19 for the first time, prevailed 6-3 6-4 in the battle of the Grand Slam champions after 79 minutes on No.1 Court.

Swiatek had won the two previous meetings between the players - both of which came in major events, at the 2020 French Open final and this year's Australian Open.

The four-time Roland-Garros winner made a statement of intent, breaking her opponent twice in her opponent's first two service games on the way to taking the opening set.

Former Australian Open champion Kenin, who stunned Coco Gauff in the first round 12 months ago, looked to respond and forced a break-point opportunity at 4-3 down in the second set.

However, the American saw it go begging as she sent a forehand into the net, and the set remained on serve as Swiatek set up a second-round clash with Croatia's Petra Martic.

"On this surface, it's not about the result for me, about the progress," the Pole said in her on-court interview. "I'm just trying to be better every day.

"It was a solid start and not an easy draw, so I'm happy that I have a chance to play another match here. It's not easy to play a Grand Slam champion in the first round, so we have to be ready for everything.

"Obviously, I had a great beginning of the season, so I feel like I can come here and not worry about points or anything, and just focus on what I want to focus on. These are experienced players, so there’s no time to get into the tournament."

Data Debrief: Super Swiatek matches Henin and Radwanska

Swiatek arrived at Wimbledon with five titles to her name already this season, including three on the spin in Madrid, Rome and the French Open.

The world number one has now won each of her last 20 matches, achieving that feat for the second time in her career. Justine Henin in 2005 was the last player to register multiple streaks of 20+ WTA match wins before turning 24.

Notching her fifth straight win against a former major champion, Swiatek has now registered 72 Grand Slam singles wins, more than any other woman since the turn of the century.

She is also only the second player in the Open Era to win in the opening round of all the first 18 major events in a single decade, after compatriot Agnieszka Radwanska did so in the 2010s.

On this day in 2020, Sofia Kenin won the Australian Open women’s singles title with a 4-6 6-2 6-2 victory against Garbine Muguruza.

The then-21-year-old American had never previously played beyond the fourth round of a grand slam and became the youngest winner of the title since Maria Sharapova in 2008.

She also followed in the footsteps of Naomi Osaka, Ashleigh Barty and Bianca Andreescu, who all won their first slam finals in brilliant fashion in the previous 18 months.

Kenin’s emotions showed at various points during the deciding set and she dropped her racket and covered her face with her hands in disbelief when Muguruza’s second serve landed long on match point.

“These past two weeks, there have been a lot of emotions,” she said post-match.

“You guys could see after the match how much it all meant to me.

“This is such an honour. I’m so proud of myself, my dad, my team, everyone that has been around me. We’ve all worked hard. We’ve been through tough times. We did it. We fought. I’m just on cloud nine.”

Kenin followed up her Australian Open victory by reaching the final of the French Open later that year in October, but was beaten by Iga Swiatek.

Iga Swiatek won the battle of the grand slam champions against Sofia Kenin to reach the second round of the Australian Open.

Kenin lifted her first major title here in 2020 before losing to Swiatek in the French Open final the same year but has struggled since with injuries and a loss of form.

The American remains a dangerous player, though, and knocked Coco Gauff out in the first round of Wimbledon last year.

She served for the opening set before Swiatek fought back to take it in a
tie-break, and the Pole was the steadier in the second to claim a 7-6 (2) 6-2
victory.

“For sure, it wasn’t the easiest first round,” said the world number one. “She played really well. I tried to find my rhythm, especially in the first set. I’m happy at the end of the set I could win the most important points.

“I’m happy that I am through and I could play a little bit better in the second set.”

Remarkably, Swiatek was the only player in her initial section of the draw not to have made an Australian Open final.

Next she will take on another American in Danielle Collins, who ended Swiatek’s best run in Melbourne so far by beating her in the semi-finals two years ago before losing to Ashleigh Barty.

That is Collins’ only victory in five meetings with Swiatek, who won their most recent match 6-1 6-0 in Cincinnati last summer.

“I can’t say that I have an easy draw here,” said Swiatek. “I’ll try to do my best. Danielle is a really good player. We played really tight matches. On the other hand, our last match, from the score, I had it under control.

“Every match is different. I’m not going to anticipate anything. I’m just going to be ready and we’ll see.”

Collins was a 6-2 3-6 6-1 winner over former Australian Open, Wimbledon and US Open champion Angelique Kerber.

The German is part of a quartet of mothers making their Melbourne returns along with Caroline Wozniacki, Naomi Osaka and Elina Svitolina having given birth to daughter Liana last February.

“It is for sure different to be back like this,” said the 35-year-old. “I think I’m open more than before, and also the other players are. I’m also more relaxed so I feel that they appreciate it and I think it’s nice to see so many moms are back on tour.

“It is a long way to be back and to play on a high level again. But, on the other side, I have the experience, I know how it is. I played so many grand slams over the years. So I’m more trying to find my rhythm, to being on court and feeling good again.”

There were also victories for two other former grand slam winners, with 18th seed Victoria Azarenka beating Camila Giorgi 6-1 4-6 6-3 and Sloane Stephens seeing off Olivia Gadecki 6-3 6-1.

Top seed Jessica Pegula cruised into the Charleston Open third round with a straight-sets victory over Anna Blinkova on Wednesday.

The American world number three triumphed 6-2 6-0 in 65 minutes, winning the second set to love in 27 minutes.

Blinkova, who is ranked 63rd in the world, was no match for Pegula, who won 71 per cent on first serve and 65 per cent on her second. Pegula also generated 10 break points, winning 71 per cent on the Russian's second serve.  

The American will take on Romanian 15th seed Irina-Camelia Begu in the round of 16, after she toppled resurgent 2020 Australian Open winner Sofia Kenin 6-1 6-4.

Defending champion and fourth seed Belinda Bencic triumphed in the evening session, breezing past Canada's Katherine Sebov 6-0 6-3 in 62 minutes.

Bencic will meet Shelby Rogers in the third round with the American edging countrywoman Caty McNally 6-7 (4-7) 7-5 6-1.

Ninth seed Madison Keys beat Hailey Baptiste 6-1 6-2, setting up a third-round clash with eighth seed Magda Linette who got past Varvara Gracheva 6-7 (3-7) 7-5 6-4.

Third seed Daria Kasatkina defeated Madison Brengle 6-2 6-1, progressing to face 38th ranked American Bernarda Para who beat Cristina Bucsa 6-3 6-4.

Spaniard Paula Badosa won 7-5 7-6 (8-6) over 2021 US Open runner-up Leylah Fernandez and will face Diana Shnaider who upset fifth seed Veronika Kudermetova 6-4 6-3.

Eugenie Bouchard's campaign at the Copa Colsanitas was halted in the second round with a 6-0 6-7 (7-9) 6-4 loss to fourth seed Kamilla Rakhimova.

World number five Ons Jabeur is through to the third round of the Charleston Open after making a winning start in a 6-3 6-3 triumph over Lesia Tsurenko on Tuesday.

Jabeur, a finalist at both Wimbledon and the US Open this past season, received a bye through to the second round thanks to her status as the second seed, and she had to save three break points in the opening game of the match against Tsurenko.

After repelling the early push, Jabeur rattled off the first five games to take a commanding lead, and she secured another break to begin the second frame.

Meanwhile, with half of the field still completing their first-round matchups, 12th seed Paula Badosa proved too strong for Egypt's Mayar Sherif in a comfortable 6-3 6-1 victory.

Spain's Badosa will play Canada's Leylah Fernandez in the second round after the promising 20-year-old took just 72 minutes to dispatch Russia's Evgeniya Rodina 6-3 6-2.

Rodina was the only loss from the four Russians in action on Tuesday, with Anna Kalinskaya defeating Alize Cornet 7-6 (7-4) 4-6 6-2, 19-year-old Diana Shnaider eliminating Alycia Parks 6-4 6-3, and Varvara Gracheva prevailing 7-6 (7-3) 6-2 against Anna-Lena Friedsam.

Bernarda Pera advanced past Clare Liu 6-4 6-7 (1-7) 6-3 in one of the all-American showdowns, while ninth seed Madison Keys beat Emma Navarro 6-4 6-3 and Shelby Rogers took out Danielle Collins 6-7 (2-7) 6-4 6-1 in the others.

Sofia Kenin, the 2020 Australian Open champion, handled the challenge of Aliaksandra Sasnovich 6-1 6-7 (5-7) 6-1, and two-time Australian Open champion Victoria Azarenka came back to defeat Sloane Stephens 3-6 6-3 6-2.

Former world number three Elina Svitolina's first game back on the WTA Tour in more than 12 months ended in a near three-hour defeat to Yulia Putintseva in the Charleston Open first round on Monday.

Svitolina, 28, had been off the tour for a combination of injury and pregnancy, but was back in action for the first time since giving birth to her and male tennis player Gael Monfils' daughter Skai in October.

The Ukrainian, who reached both the Wimbledon and US Open semi-finals in 2019, won the first set after rallying back from 3-1 down in a tie-break

But the Kazakh world number 47 responded and prevailed 6-7 (3-7) 6-2 6-4 in two hours and 48 minutes, with Putintseva sapping her opponent's energy with frequent drop shots.

Former Australian Open champion Sofia Kenin was on track for victory in a topsy-turvy clash with Aliaksandra Sasnovich before rain intervened, forcing it to be re-scheduled for Tuesday with the American leading 6-1 6-7 (5-7) 3-0.

World number 50 Sloane Stephens fought back after an early scare to beat qualifier Louisa Chirico 3-6 6-1 6-2, while Alize Cornet breezed past Fiona Crawley 6-0 6-2.

Jil Teichman was one of three seeds to lose in the first round, going down 6-2 3-6 6-2 to 17-year-old Linda Fruhvirtova.

Ukrainian 11th seed Anhelina Kalinina lost 7-6 (8-6) 6-4 to Anna Kalinskaya, while 10th seed Zhang Shuai was beaten 6-4 1-6 6-3 by Julia Grabher.

Eugenie Bouchard returned for the first time since the 2023 Australian Open due to injury with a win over Ylena In-Albon 6-3 6-2 at the Copa Colsanitas in Bogota.

Third seed Nuria Parrizas Diaz was knocked out by Briton Francesca Jones, who is ranked 817th in the world, 7-6 (7-3) 6-1 in a major shock.

Aryna Sabalenka needed just 68 minutes to dispatch Marie Bouzkova 6-1 6-2 in Sunday's third round of the Miami Open.

Sabalenka hit 26 winners in the victory and now has 250 at WTA 1000 level for the season, representing one of only two female players with more than 200 in 2023.

The world number two, who is the top seed in the tournament after Iga Swiatek's withdrawal, has now won 19 of her past 21 matches, with her only losses in that span to Elena Rybakina and Barbora Krejcikova.

She will get the chance to avenge that loss to Krejcikova next after the Czech Republic representative knocked out hometown star Madison Keys 7-6 (7-4) 6-3.

Former French Open winner Krejcikova registered her 10th WTA 1000 level win against Keys, becoming only the second player to achieve that this season.

Former Australian Open champion Sofia Kenin fell 6-4 6-4 to Canada's Bianca Andreescu, who continued her strong run after previously knocking out seventh seed Maria Sakkari and 2021 US Open champion Emma Raducanu.

In a serve-dominated match, 2019 US Open champion Andreescu sent down seven aces, maintaining 70 per cent first serve percentage.

Ninth seed and former Olympic gold medallist Belinda Bencic was eliminated 7-6 (10-8) 6-3 by 18th seed Ekaterina Alexandrova, who will take on Andreescu in the next round.

Marketa Vondrousova won her all-Czech matchup against 17th seed Karolina Pliskova, and their compatriot Petra Kvitova enjoyed a 6-4 7-6 (7-3) triumph over recent Monterrey Open champion Donna Vekic.

Romania's Sorana Cirstea made it seven wins from her past eight matches with a 7-5 6-1 result over Karolina Muchova, having knocked off fifth seed Caroline Garcia in the second round.

Varvara Gracheva ensured a strong day for the Russians with a 6-1 6-2 demolition of Magdalena Frech in a battle of two unseeded players.

Emma Raducanu was bundled out of the Miami Open in the first round by form US Open champion Bianca Andreescu in a three-set match that lasted two hours and 35 minutes on Wednesday.

The Briton, who won the US Open in 2021, went down 6-3 3-6 6-2 in a genuine tug-of-war against the 31st-ranked Canadian.

Andreescu sent down seven aces for the match, including four in the first set along with 12 winners as she claimed an early lead.

Raducanu responded with greater aggression, securing the crucial break in the eighth game, before serving out to level the contest.

But Andreescu showed composure and quality in the big points in the final set, winning the final four games to round out the victory, sealing a second-round clash with seventh seed Maria Sakkari.

Andreescu finished with 32 winners compared to Raducanu's 20, while the Briton committed 40 unforced errors.

World number 42 Shelby Rogers edged out USA compatriot Sloane Stephens in just under two hours, winning 6-4 3-6 6-2. Rogers will take on second seed Aryna Sabalenka, who is arguably the tournament favourite after top seed Iga Swiatek's withdrawal, in the next round.

Rogers was one of five Americans to progress, including 2020 Australian Open champion Sofia Kenin who defeated Australia's Storm Hunter 6-0 7-6 (7-5).

World number 35 Amanda Anisimova retired down 7-6 (7-5) 5-2 to countrywoman Madison Brengle.

Leylah Fernandez, the player whom Raducanu beat in the 2021 US Open final, advanced into the second round with a 6-4 6-3 victory over Lesia Tsurenko in 88 minutes.

Top seed Iga Swiatek spurned the chance for a double-bagel victory over Claire Liu at the Indian Wells Open on Saturday but she still cruised into the third round in 66 minutes.

The 21-year-old Pole, who won last year's Indian Wells, had match point at 6-0 5-0, before Liu rallied back on serve to avoid the ignominy of a double-bagel defeat, with Swiatek eventually winning 6-0 6-1.

Swiatek was in a dominant mood, winning 57 of 83 points for the match and converting five of nine break points generated. She dropped only 11 points in seven service games.

The three-time grand slam champion is 13-3 on the season, with all 13 wins coming in straight sets. In five of those matches, she has dropped just one game.

Former US Open winner Emma Raducanu moved into the third round with a 7-6 (7-3) 6-2 win over 20th seed and 2023 Australian Open semi-finalist Magda Linette.

Raducanu's win meant she has put together back-to-back victories for the first time since September, setting up a clash with 13th-seed Beatriz Haddad Maia after she beat Katerina Siniakova 5-7 7-6 (7-4) 6-3.

Fourth seed Ons Jabeur fought back from a set down to prevail over Magdalena Frech 4-6 6-4 6-1 in one hour and 44 minutes.

Former US Open champion Bianca Andreescu also overcame an early deficit to win 4-6 6-4 6-3 over Peyton Stearns.

Reigning Wimbledon champion Elena Rybakina got the edge in a tight two-set clash with 2020 Australian Open winner Sofia Kenin, triumphing 7-6 (8-6) 7-6 (7-5) in two hours and 10 minutes. Rybakina fought back from 4-1 down in the second frame.

Fifth seed Caroline Garcia overcame a wobble to win 6-1 6-7 (4-7) 6-4 over Hungary's Dalma Galfi, with 30th seed Leylah Fernandez her next opponent after beating Emma Navarro 6-2 6-4.

Two-time major winner and three-time US Open finalist Victoria Azarenka was the big casualty from the day's play, losing 7-6 (7-1) 6-3 to 2021 Australian Open semi-finalist Karolina Muchova.

Liudmila Samsonova progressed after a marathon battle at the Dubai Tennis Championships, while Petra Kvitova breezed through as the seeds escaped unscathed on Sunday.

Two-time Wimbledon champion Kvitova, the 12th favourite in the United Arab Emirates, eased past Italy's Martina Trevisan 6-2 6-1 to make a dominant start.

World number 15 Samsonova was made to work to beat Paula Badosa, winning 6-7 (3-7) 7-6 (7-5) 6-4 to tee up a clash with Qinwen Zheng, who overcame compatriot Zhang Shuai in straight sets.

Samsonova's triumph took three hours and 22 minutes, the longest match of the WTA Tour season thus far, in a thrilling first-round encounter between two top-20 players.

"Playing against Paula is always tough," 14th seed Samsonova said in her on-court interview. "She's doing unbelievable, so I'm really proud that I stayed on the court until the end.

"I think I'm growing match after match, day by day. I know it's a long journey, and I hope to continue like that."

Barbora Krejcikova, the 2021 French Open champion, cruised into the last 32 with a comfortable 6-4 6-2 victory over Irina-Camelia Begu as she aims to go one better than her runners-up finish two years ago in Dubai.

Another routine victory saw American Madison Keys ease past Jasmine Paolini 6-1 6-1, but there was no such luck for 2020 Australian Open champion Sofia Kenin.

She was dispatched 6-1 6-1 by world number 26 Marie Bouzkova, while Amanda Anisimova claimed a 6-3 6-2 win over veteran two-time grand slam finalist Vera Zvonareva.

Viktoriya Tomova had too much for Kaia Kanepi in a 6-3 6-1 success, with her reward a second-round clash against third seed Jessica Pegula.

World number four Pegula lost to the in-form Iga Swiatek in the Qatar Ladies Open final on Saturday, and Leylah Fernandez will face the Pole next after beating Julia Grabher 6-4 6-2.

Iga Swiatek started the defence of her Qatar Open title by taking less than an hour to beat Danielle Collins on Wednesday.

Playing for the first time since she was knocked out of the Australian Open by Elena Rybakina in the fourth round last month, normal service was resumed by the domineering world number one in Doha.

The top seed brushed Collins aside in only 53 minutes, racing to a 6-0 6-1 victory to march into the third round.

Collins only won four points as she suffered the misery of a first-set bagel, an inspired Swiatek taking the opener in only 21 minutes.

Swiatek's run of games won was ended at nine when Collins got on the board at 3-1, but the Pole broke for a fifth time before serving it out for an emphatic victory.

The 21-year-old three-time grand slam champion, who made only six unforced errors, will do battle with Belinda Bencic for a place in the quarter-finals.

Bencic beat two-time champion Victoria Azarenka 1-6 7-6 (7-4) 6-4 to take her place in the last 16, storming back from 4-1 down in the second set when she appeared to be on her way out.

Second seed Jessica Pegula saved two match puts as she dug deep to beat Jelena Ostapenko 6-2 2-6 7-5 to set up a meeting with Beatriz Haddad Maia, who beat Daria Kasatkina in straight sets.

Fourth seed Coco Gauff got the better of Petra Kvitova 6-3 7-6 (8-6), while Veronika Kudermetova and Maria Sakkari also made it through.

Belinda Bencic will play Daria Kasatkina in the final of the Adelaide International 2, though neither of them had to play a semi-final.

Bencic was due to go up against Veronika Kudermetova in the second scheduled semi-final on Friday, only for the Russian to withdraw due to a hip injury.

It was a similar story for Kasatkina, who received a walkover after Paula Badosa pulled out of their match, citing a thigh problem.

While Bencic and Kasatkina will now get the chance to claim a trophy early in the season, the focus for Badosa and Kudermetova will be on regaining fitness in time for the Australian Open, which starts next week.

Badosa was confident she can recover for the upcoming major, where she has been drawn against American Caty McNally in the first round.

"I'm really disappointed that I had to withdraw because I was really looking forward to the match," Badosa told reporters.

"When I was playing [against Beatriz Haddad Maia], it was a very tough match, especially physical, so I felt a little bit in my abductor. I felt like I pulled it a little bit.

"I feel a little bit worse, so I have the Australian Open ahead, and I hope I can recover for that."

Badosa needed two hours and 35 minutes to get past the Brazilian on Thursday, having knocked off Anett Kontaveit and Kaia Kanepi in the earlier rounds.

"I played three really good matches," the Spaniard said. "I think that helps me, as well, on my confidence for the tournaments ahead. Now it's something that I cannot control, so it is what it is."

At the Hobart International, Elisabetta Cocciaretto set up a showdown with Lauren Davis.

Sofia Kenin, the 2019 champion, fell 7-5 4-6 6-1 to world number 67 Cocciaretto, who has reached her first Tour-level singles final.

"It’s unbelievable for me to be here in the final of such a great tournament, and I’m really happy about my performance," Cocciaretto said.

"[Kenin is] a very good player, I was a junior when she won the grand slam [2020 Australian Open], so for me it's an honour to play against her."

Davis, meanwhile, saw off Anna Blinkova in straight sets. She has not featured in a Tour-level final since clinching the trophy in Auckland in 2016.

Veronika Kudermetova saved five match points as she beat Danielle Collins to reach the Adelaide International 2 semi-finals before Belinda Bencic knocked Caroline Garcia out.

Sixth seed Kudermetova showed great defiance to defeat American Collins 4-6 7-6 (7-5) 6-1 on Thursday.

Kudermetova fended off five match points when serving to stay in the tournament at 6-5 down in the second set and duly forced a tie-break.

Collins, runner-up to Ash Barty in the Australian Open final last year, took a 3-0 lead in the breaker, but back came her Russian opponent to level the match.

The world number nine dominated the deciding set to seal a meeting with Bencic in the last four.

Eighth seed Bencic got the better of WTA Finals champion Garcia 6-2 3-6 6-4.

Garcia broke straight back after going 3-1 down in the final set, but Bencic broke for the fourth time in the match to go through.

Paula Badosa and Daria Kasatkina will contest the other semi-final after beating Beatriz Haddad Maia and Petra Kvitova respectively. 

Elisabetta Cocciaretto saved two match points as she came from a set down to beat Bernarda Pera 5-7 7-6 (10-8) 6-4 in the quarter-finals of the Hobart International. 

The 21-year-old Italian will now face 2020 Australian Open champion Sofia Kenin, who also stormed back to defeat Anhelina Kalinina 4-6 6-3 6-1.

Lauren Davis and Anna Blinkova will do battle in the other semi-final following wins over Wang Xinyu and Yulia Putintseva respectively. 

Emma Raducanu was in tears as she retired with an ankle injury at the ASB Classic 11 days before the Australian Open starts, while Coco Gauff beat Sofia Kenin to reach the quarter-finals.

Raducanu dished out a bagel to qualifier Viktoria Kuzmova in the first set of the round of 16 match in Auckland on Thursday, but the 2021 US Open champion was unable to continue after losing the second set 7-5.

The 20-year-old Brit ended a disappointing 2022 season early due to a wrist injury and suffered another blow ahead of the first major of this year, leaving the court in tears.

Gauff will be eyeing her maiden grand slam title in 2023 and she impressively dispatched fellow American Kenin 6-4 6-4 in the second round in the capital of New Zealand.

Top seed Gauff and her compatriot were forced to play indoors due to the rain and it was the 18-year-old who prevailed, breaking three times and saving six of the break points she faced.

The teenager will face Zhu Lin of China for a place in the semi-finals after she beat Venus Williams 3-6 6-2 7-5.

Leylah Fernandez inflicted a crushing 6-0 6-1 defeat on Julia Grabher after losing only two games in her first-round win over Brenda Fruhvirtova and the Canadian will now face Ysaline Bonaventure, who defeated Rebecca Marino in three sets.

Top seed Ons Jabeur made a winning start to the season at the Adelaide International, seeing off Sorana Cirstea 7-6 (7-3) 6-1 to set up a meeting with Marta Kostyuk

Irina-Camelia Begu claimed the scalp of Jelena Ostapenko with a 6-3 6-0 upset of the seventh seed, while Victoria Azarenka was a 6-2 7-5 winner against Zheng Qinwen and teenager Linda Noskova got past Claire Liu in straight sets.
