Barty faced a match point but the defending champion and world number one dug deep to prevail in three sets against Kristina Kucova on Thursday.
Romanian third seed Halep also needed three sets at the WTA Premier tournament in Miami.
BARTY PRODUCES COMEBACK
In her first match outside of Australia in more than 12 months, Barty survived to top qualifier Kucova in Miami.
Barty trailed 5-2 in the third set, with Kucova earning a match point at 5-3 but the Australian star saved it and won the final five games of the match to secure a spot in the round of 32.
Winner of the 2019 French Open, Barty sent down an equal career-high 15 aces in two-and-a-half hours.
"Today was really hard work, and I enjoyed every single minute of it," Barty said on court post-game. "There’s nothing like coming through a test like that, and now I get another opportunity in a couple days' time to play another tough match and test myself again."
Next up for Barty is 2017 Roland Garros champion Jelena Ostapenko, who outlasted Kirsten Flipkens 6-2 5-7 6-3.
HALEP REACHES MILESTONE
Halep brought up her 400th WTA main-draw triumph with a 3-6 6-4 6-0 victory over France's Caroline Garcia.
After dropping the opening set, Halep won 11 of the final 12 games to move through to the next round.
Halep won in one hour, 48 minutes, drastically improving on her first serve after the opening set while coming to grips with Garcia's kick serve.
"I needed time to get used to it and to get the rhythm," Halep said about Garcia's serve having improved her head-to-head record to 7-1, with Anastasija Sevastova awaiting in the last 32 after eliminating American sensation Coco Gauff.
Halep received attention on her shoulder early in the second. "I struggled with my serve," Halep said. "I struggled with my shoulder a little bit, so the attention was a little bit on the pain. [After that] I started to relax myself."
KERBER'S DOUBLE BAGEL
Three-time grand slam winner Angelique Kerber has been up and down in recently, but she flexed her muscles with a 6-0 6-0 humiliation of Renata Zarazua.
Aryna Sabalenka – the seventh seed – was another one to fend off match points before rallying 0-6 6-3 7-6 (11-9) past Bulgarian qualifier Tsvetana Pironkova in a gutsy.
Last year's French Open champion Iga Swiatek knocked off Barbora Krejcikova 6-4 6-2, while ninth seed and two-time Wimbledon champion Petra Kvitova got past Aliza Cornet 6-0 6-4.
Fifth seed Elina Svitolina survived to beat Shelby Rogers 3-6 7-5 6-3 and two-time major winner Victoria Azarenka benefited from a walkover.
Four-time grand slam champion Osaka won the opening game, before Saville was unable to continue due to a scary-looking injury to her left knee.
The former world number one will now face a second round match with world number 16 Beatriz Haddad Maia, who eased to a straight sets victory over Yuki Naito.
Karolina Pliskova secured her place in the next round in Tokyo with a 6-2 6-1 demolition of Isabella Shinikova, while Zhang Shuai will face second seed Caroline Garcia on Wednesday after overcoming Mai Hontama in two sets.
In Seoul, Jelena Ostapenko's hopes of repeating her 2017 heroics at the Korea Open are still alive after the number one seed narrowly beat 19-year-old Jeong Bo-young.
The world number 19 looked to be cruising after the opening set, but the unheralded South Korean hit back in the second and took it to a tie-break in the third, before Ostapenko's class showed as she won the crucial tie-break 7-2.
Elsewhere, 2021's beaten finalist Kristina Mladenovic saw off wildcard Park So-hyun 6-4 4-6 6-3, while second seed Ekaterina Alexandrova overcame a worrying second set to beat Asia Muhammad 6-1 3-6 6-1.
Wimbledon semi-finalist Tatjana Maria is also safely through to the second round after a tight 7-6 (7-5) 7-6 (7-5) triumph over Eugenie Bouchard.
The American beat Maryna Zanevska 6-3 7-6 (7-4) on Saturday, hitting 35 winners and 13 aces on the way to victory.
Parks has risen through the ranks in the last year, and explained how a laid back attitude has been the secret to her success in France.
"I think the key was just staying focused, and taking my time out there," Parks said after her win. "Every time I got ahead of myself, I would kind of lose points, so I would tell myself to slow down.
"This whole week, I'm kind of relaxed this week and just kept playing my game and doing me."
The 22-year-old will face Garcia on Sunday after she eased to a 6-2 6-2 win against Camila Osorio in just an hour and 12 minutes.
At the Thailand Open, Lesia Tsurenko will take on China's Zhu Lin in the final after the Ukrainian came past top seed Bianca Andreescu.
The Canadian retired hurt in the second set, though Tsurenko already led 7-5 4-0.
"The way [Andreescu was] playing every point, like she has an idea in every point, so of course she's an amazing player," Tsurenko said. "It was a big challenge for me to handle this, and I was just saying to myself that I have to keep fighting, and this is probably the main key that worked today for me."
Zhu defeated compatriot Xinyu Wang 6-2 6-4 to advance to Sunday's final.
Fast-rising American Alycia Parks pulled off a stunning victory over world number five and home favourite Caroline Garcia in the Lyon Open final on Sunday.
Playing her first final on the main WTA tour, Parks earned a 7-6 (9-7) 7-5 win against last season's WTA Finals champion.
The Atlanta-born world number 79 won two titles at lower-tier WTA 125 events in December, triumphing in Andorra and the French city of Angers while many players were enjoying an off-season.
Yet this week has been a step up from that level, and 22-year-old Parks capped her run to the final by taking down the top seed and darling of the crowd.
"This title means a lot to me," Parks said. "France has a special part in my heart right now."
A to-and-fro tie-break in the opening set eventually went Parks' way after a stray forehand from Garcia.
A painful fall when running to her right on the baseline meant Parks needed medical attention early in the second set, but she was able to carry on.
Garcia tried to rouse the crowd after clinging to her serve in the eighth game to stay on level terms, and there were unsporting cheers for a double fault from Parks at the start of the ninth.
Yet Parks was not knocked out of her stride, with the player who stood 199th on the rankings at this time last year completing the biggest win of her career when Garcia sent down a double fault on match point.
The Kazakh player took time to get going but eventually prevailed 4-6 6-1 6-2 against her Brazilian opponent in the last-16 clash to make it seven wins in a row in the competition.
While the third seed was able to bounce back, there was no such luck for Chinese sixth seed Zhang Shuai as she was soundly beaten 6-1 6-0 by Serbian Aleksandra Krunic.
China's Wang Xiyu awaits Krunic in the quarter-finals after beating Romanian Ana Bogdan 7-6 (7-2) 7-6 (12-10) in a match lasting two hours and 43 minutes.
Elisabetta Cocciaretto was also victorious on Thursday, the Italian seeing off Wimbledon doubles champion Katerina Siniakova 7-5 4-6 7-5 in the final match of the day.
At the Ladies Open Lausanne, surprise Wimbledon singles quarter-finalist Jule Niemeier made it through to the last eight of another tournament, enjoying a 6-4 6-2 triumph against fellow German Eva Lys.
Caroline Garcia made it through to her fourth quarter-final of the year with a 6-1 6-4 win over French compatriot Leolia Jeanjean.
Qualifier Olga Danilovic saved a match point before going on to beat Anna Kalinskaya 6-3 3-6 7-5, while Belinda Bencic advanced from an all-Swiss battle with a 6-3 6-4 win over Susan Bandecchi.
Putintseva was the strong favourite to overcome world number 86 Parry, but it was the latter who prevailed 6-3 6-4 to reach her first tour-level quarter-final.
Caroline Garcia also advanced through after recovering from a heavy first-set loss to overcome Elisabetta Cocciaretto 0-6 6-3 6-4.
Home hope Lucia Bronzetti awaits in the final eight following a 6-1 6-3 win over Elina Avanesyan, while Nuria Parrizas-Diaz beat Julia Grabher 6-2 6-4 in the day's other match.
At the Hamburg European Open, in-form Bernarda Pera beat Katerina Siniakova 6-3 6-1 to make it 10 wins in a row without dropping a set.
Pera is through to her second semi-final in a row, where she will take on Maryna Zanevska, who saw off Aliaksandra Sasnovich in straight sets for a second career top-50 victory.
Top seed Anett Kontaveit advanced after Andrea Petkovic withdrew injured when 6-0 2-0 down, but Barbora Krejcikova was on the end of a 6-1 6-3 upset against Anastasia Potapova.
The Kazakh Putintseva struggled to get going, failing to convert any of her seven break points, as the Serbian Krunic broke her serve four times en route to a 6-2 6-2 win.
Bernarda Pera will await Krunic in the final in Hungary, after her 6-3 6-4 victory over Anna Bondar.
Bondar raced out to an early 3-0 lead in the first set, but Pera rattled off six games in a row to take the opener.
The Croatian-born American then won the first three games of the second set, before overcoming a desperate late Bondar charge to break her at 5-4 and finish things off.
Sunday's final will be the third meeting between Krunic and Pera with the latter winning both of the previous contests, firstly in the quarter-finals of the Guangzhou Open in 2018 and then in Moscow in 2021.
At the Ladies Open Lausanne, qualifier Olga Danilovic cruised through to the final with a 6-3 6-2 victory over Russian Anastasia Potapova.
Danilovic won her first WTA Tour singles event in Moscow in 2018, overcoming Potapova after three sets.
And the world number 124 was victorious against Potapova once more in Switzerland to seal her place in her second WTA Tour singles final.
The Serbian 21-year-old will meet Petra Martic in the decider on Sunday after Martic overcame sixth seed Caroline Garcia 6-4 1-6 6-3.
Neither player had dropped a set on their way to the semi-finals, but things at Lausanne were tied up at one set each after two.
Garcia had won all three of her previous meetings with Martic, but the Croatian's two crucial breaks of serve in the final set were telling, as she held her nerve to reach the final against Danilovic.
Garcia, the world number 10, entered the contest off back-to-back losses for the first time since March, and Collins made it three in a row as she was just a little too good with both her serving and return game.
Collins won 63 per cent of her service points, with Garcia at 52 per cent, and she ended up securing five breaks in the match.
She will play Martina Trevisan in the second round after the Italian defeated Colombian qualifier Camila Osorio 6-3 6-4.
Neither player had an ace in the match, but the big differentiating factor was Trevisan's ability to win points off her second serve, converting 50 per cent of her chances while Osorio won only one of nine (11 per cent).
The only qualifier of the day to get a win was Louisa Chirico, who beat fellow American Alison Riske-Amritraj 1-6 7-5 7-6 (7-5).
Chirico, the world number 196, will be rewarded for her win with a showdown against world number four Paula Badosa.
Madison Keys had no issues dealing with Australian qualifier Ellen Perez 6-1 6-4 in just over an hour, and Coco Vandeweghe defeated Sofia Kenin 6-1 1-6 6-4.
In the last match of the night, Canada's Bianca Andreescu won a two-hour-and-40-minute battle against Russia's Liudmila Samsonova 7-6 (7-1) 4-6 6-2.
In a match halted twice for extended periods by rain, Garcia triumphed 6-2 4-6 6-1 in the semi-final that lasted two hours and five minutes.
Garcia's victory over Sabalenka secured her spot in the decider against Petra Kvitova, who beat Madison Keys in the other semi-final earlier on Saturday.
The victory also adds another top-10 scalp to Garcia's list from this week's Cincinnati event, having knocked out fourth seed Maria Sakkari and seventh seed Jessica Pegula en route to the final four.
The world number 35 had also beaten top-ranked Iga Swiatek during a run to the Poland Open title three weeks ago.
Garcia has a Tour-leading 26 main-draw victories since June with title wins in Bad Homburg and Warsaw in that stretch; next most match wins in that stretch is Simona Halep (19) and Beatriz Haddad Maia (17).
Saturday's win was fueled by a strong first-serve points won percentage of 81.3 per cent for Garcia, sending down 8-4 aces while Sabalenka was not helped by 7-1 double faults.
The 28-year-old, whose highest rank was fourth in 2018, saved seven break points while converting six of the 13 she generated.
She had to come through qualifying to earn a place in the Cincinnati main draw and looked like racing past Sabalenka after taking the opening set in impression fashion.
A two-and-a-half-hour rain delay halted Garcia's progress at 1-1 in the second set, and it was Sabalenka who returned the strongest from the break.
Garcia needed her left arm bandaging when trailing 5-4 in the second set, forcing Sabalenka to endure a long wait to serve to level the match.
Just as the match looked to be tilting the Belarusian's way, an improved Garcia broke to lead 3-1 in the deciding set; however, rain returned in the next game with Garcia 30-15 up on serve, causing another hold-up.
But Garcia would not be denied after play resumed approximately 90 minutes later, winning the final three games to secure an historic place in the decider.
There was a certain irony about that, given Garcia is the player Murray famously once tipped to become a world number one.
But seeing fellow Briton Murray battle past Taro Daniel prior to her own match fuelled Raducanu for her opening test at the WTA Indian Wells Open.
While it was not always comfortable for the 11th seed, Raducanu recovered from a shaky second set to win 6-1 3-6 6-1 against her French opponent.
Murray's pronouncement about Garcia's prospects came on Twitter in 2011 as he watched the then little-known player take on Maria Sharapova in the French Open.
Garcia reached as high as number four in 2018, and it is now Raducanu who looks the likelier future number one, having landed a breakthrough grand slam against all the odds in New York last year.
Raducanu was beaten on her Indian Wells debut by Aliaksandra Sasnovich last October, so to land a first win came as a relief.
She said in an on-court interview: "It's amazing to be back and I'm so happy to have got my first win in the desert here. I hope to come back for many more years.
"I thought the level of tennis was pretty high today, and it means a lot to have come through that because it could have gone either way."
Raducanu said Garcia "climbed on top" of her game in the second set, but, like Murray earlier, she kept enough back for a decider.
Speaking to Amazon Prime, she revealed how seeing Murray show his battling qualities against Daniel reminded her of what it takes in trying circumstances.
"I was watching pretty much the whole match until I had to go warm up," Raducanu said. "He was down, and it was a really tough one. To see him, I kind of wanted to follow him and learn from him and he kind of inspired me to dig in today when it got tough."
She added: "To get this win after a stop-start year that I've had at the beginning, it means a lot. I'm just really happy to have given myself another opportunity.
"For sure it's difficult after dropping a set. I knew I'd slipped up, and I'd missed too many first serves, and I was just thinking... 'Just think how bad you're gonna feel after the match if you let this one go'."
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.
It was an ominous start for Cirstea, being broken to love in the opening game, but she stuck with second seed Sabalenka and broke back, before ultimately being pipped to the first set by the impressive Belarusian.
The key was on break points, with Sabalenka claiming all five that she won against the Cirstea serve, while saving six of eight on her own as she ultimately eased to victory.
Sabalenka now has 26 wins on clay in the WTA since 2021, with only Ons Jabeur (37), Iga Swiatek (34), Paula Badosa (31) and Coco Gauff (28) having more during this time.
Gauff also advanced after a routine 6-4 6-1 win over Irene Burillo Escorihuela, making the sixth seed in Madrid the first player to win 35 WTA-1000 main draw matches as a teenager since 2009.
Ninth seed Maria Sakkari defeated Arantxa Rus 6-4 6-4 and fifth seed Caroline Garcia also had few problems against Yulia Putintseva, winning 6-3 6-4.
However, it was not a good day for 10th seed Petra Kvitova, who was beaten 7-6 (11-9) 6-1 by Jule Niemeier, while 13th seed Beatriz Haddad Maia also lost, 7-6 (8-6) 6-3 to Mirra Andreeva and 20th seed Donna Vekic was eliminated in straight-sets by Rebeka Masarova.
Jelena Ostapenko took just 61 minutes to get past Linda Fruhvirtova 6-0 6-3, and will face 14th seed Liudmila Samsonova next, who did not take much longer to see off Maryna Zanevska 6-2 6-3.
There were also wins for Elise Mertens, Badosa, Camila Osorio, Shelby Rogers, Mayar Sherif, Magda Linette and Irina-Camelia Begu.
Sakkari is one of the players needing a strong result in the tournament to break into the top-eight of the world rankings to qualify for the upcoming WTA Finals, entering the week at 10th, but only needing to make up one spot, with number eight Simona Halep out due to injury.
With her victory over Kostyuk, Sakkari avoided notching four consecutive losses for the first time this season, and will likely only need one more win to move into WTA Finals contention.
Her next opponent appears to be world number 16 Danielle Collins, who had no issue dispatching American compatriot Caroline Dolehide 6-4 6-1 to book her second-round fixture against Magdalena Frech after the Polish qualifier beat Yulia Putintseva 6-3 6-4.
World number seven Daria Kasatkina also should be locked into the WTA Finals after cruising past China's Lin Zhu 6-1 6-2, while 18th-ranked Beatriz Haddad Maia's season is over after a disappointing 7-5 6-2 upset loss to Katerina Siniakova.
Petra Kvitova needed to reach the final to have a chance of qualifying, but after a strong first set she fell 3-6 6-2 6-0 against Canada's Bianca Andreescu. In a good day for the Canadians, Eugenie Bouchard also beat Kayla Day 7-5 6-3 as the former world number five fights her way back up the rankings after a long injury layoff.
Italy's Elisabetta Cocciaretto defeated Russia's Anastasia Potapova 6-2 6-1, while Latvia's top talent Jelena Ostapenko cruised past America's Lauren Davis 6-1 6-3.
Madison Keys was too strong for Magda Linette in a 6-3 6-3 triumph, and in an all-Czech matchup, Marie Bouzkova downed Tereza Martincova 6-2 7-5.
Croatia's Donna Vekic eliminated Brazil's Laura Pigossi 6-4 6-1, and Italy's Martina Trevisan showed why she is top-30 in the world with a convincing 6-4 6-3 straight sets win against Japan's Nao Hibino.
In the last match of the night, world number 10 Caroline Garcia survived an early scared to come from behind and defeat Rebecca Marino 6-7 (2-7) 6-3 7-6 (7-5).
Former US Open champion Stephens, ranked 49th in the world, defeated Dodin 6-7 (6-8) 6-4 6-2.
Stephens progresses to the second round where the top seeds, including top three Ash Barty, Naomi Osaka and Simona Halep, will be introduced and she will face 28th seed Amanda Anisimova.
Danielle Collins, Wang Qiang, Alize Cornet and Caroline Garcia were among the other winners on Wednesday, while Svetlana Kuznetsova bowed out.
SLOANE FIGHTBACK
Stephens had endured a dismal start to 2021, enduring an 0-4 win-loss record to begin the year.
The 28-year-old American was made to do it the hard way against Dodin on Wednesday, dropping the first set in a tie-break.
Stephens improved on her return in the second set, winning 73 per cent of points off Dodin's second serve before running away with the match in the last.
"It's been a rough one for me lately, so I'm really pleased to get through that, fight my way through it and make it happen somehow," Stephens said post-match.
FORMER MAJOR WINNER GONE
Two-time grand slam winner Kuznetsova was the major first-round casualty, going down 2-6 6-2 6-1 to France's Alize Cornet.
Kuznetsova, who is now ranked 35th in the world, bows out with Cornet to face ninth seed Petra Kvitova.
Collins got past France's Kristina Mladenovic 6-3 6-3 with the 40th-ranked American setting up a second-round clash with 32nd seed Veronika Kudermetova.
Wang, ranked 38th in the world, also progressed despite dropping a set in a 6-1 3-6 6-3 win over Spanish qualifier Aliona Bolsova.
SECOND-ROUND MATCH-UPS
The round of 64 will commence on Thursday, with third seed Halep to face Garcia who got past another Romanian, Mihaela Buzarnescu 6-1 6-2.
Top seed Barty will be in action against Slovakia's Kristina Kucova, while fourth seed Sofia Kenin will take on former top-10 player Andrea Petkovic.
Second seed Osaka has an assignment against 77th-ranked Australian Ajla Tomljanovic, while 14th seed Victoria Azarenka is already into the third round with opponent Laura Siegemund withdrawing after her win on Tuesday.
Swiatek made a disastrous start, going 4-0 down, and though she broke back once, was unable to find the second as Pliskova took the opening frame 6-4.
The determined Pole stepped up a level though to take the second 6-1, before breaking early in the third.
It was still an improvement for the Czech player, who lost 6-0 6-0 to Swiatek in their only previous meeting in Rome in 2021.
Pliskova kept her opponent honest on her own serve, but Swiatek had too much for the world number 17 as she clinched the decider 6-2.
Aryna Sabalenka also showcased her powers of recovery as she beat Paula Badosa despite going a set down.
The second seed won 4-6 6-4 6-4 in an even contest that saw nine breaks of serve, before the Belarusian eventually got over the line.
Sabalenka is now the player with the joint-most comeback wins over the last two seasons (13) level with Caroline Garcia, though the French star was actually the victim of a comeback herself on Friday.
Garcia won the first set against Anastasia Potapova, before the Russian came back to take it 4-6 6-3 6-3 to set up a semi against Sabalenka.
There was no need for such drama from Ons Jabeur, who eased to a 6-3 6-0 victory against Beatriz Haddad Maia in just 68 minutes to confirm a clash with Swiatek.
Garcia was the only WTA Finals player to have beaten Swiatek this year, but the world number one swept her aside with an impressive display in one hour and 23 minutes.
Swiatek remains yet to lose a set at Fort Worth and will qualify for the semi-finals should Coco Gauff fail to beat Daria Kasatkina in two sets, or if Kasatkina wins.
Garcia managed the first break in the third game of the opener, but Swiatek broke back immediately before finding another at 4-3 up, kicking on from there to take the opening set.
The Pole was excellent in the second set, breaking Garcia twice to secure another victory and inch closer to the final four.
Swiatek gets some measure of revenge for the 6-1 1-6 6-4 defeat to Garcia at the Warsaw Open quarter-finals in July, her only loss on clay over the season.
A Kasatkina win against Gauff will see Swiatek advance as group winner, while a Gauff win in three sets will seal her progression but leave her position in the group undecided.
WINNERS/UNFORCED ERRORS
Swiatek - 17/8
Garcia - 16/14
ACES/DOUBLE FAULTS
Swiatek - 1/2
Garcia - 3/3
BREAK POINTS WON
Swiatek - 4/5
Garcia - 1/6
Swiatek had not played since sustaining the issue in the semi-finals of Indian Wells over a month ago, but advanced on Thursday despite stating that she felt "rusty".
The world number one won 84 per cent of points after landing her first serve in as she made up for lost time.
Swiatek also forced eight break points, winning four of them as she took just and hour and 26 minutes to set up a quarter-final with Karolina Pliskova, who bested Donna Vekic in a thriller.
Pliskova looked to be on her way to a routine win as she claimed the first set 6-2, only for the Croatian to take the second via a tie-break.
The decider also went the distance, with Pliskova able to finally put Vekic away 6-2 6-7 (5-7) 7-6 (7-5) to book her clash with Swiatek.
Coco Gauff perhaps paid the price for taking almost three hours to beat Veronika Kudermetova on Wednesday, as the fifth seed fell to a straight-sets loss to Anastasia Potapova on Thursday, going down 6-2 6-3.
Fourth seed Caroline Garcia will go up against Potapova next after she defeated Tatjana Maria 7-6 (7-5) 6-4, while Paula Badosa had few problems seeing off fellow Spaniard Cristina Bucsa 6-1 6-2 and will face second seed Aryna Sabalenka in the last eight.
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.
Swiatek started shakily as her serve was broken in the first game of the match, and although she got it back instantly, both competitors ended up creating eight break point opportunities each in a closer-than-expected match.
She will meet England's Emma Raducanu in the fourth round after the resurgent 20-year-old collected her best win of the year, defeating 13th seed Beatriz Haddad Maia 6-1 2-6 6-4.
Raducanu, the 2021 US Open champion, has begun to work her way back up the rankings. Having come into the tournament ranked 77th in the world after an injury-riddled season, she has now won four of her past five matches, with her only loss in that span coming against world number six Coco Gauff at the Australian Open.
World number five Caroline Garcia was pushed to a third set for the second match in a row, but prevailed 6-4 6-7 (7-5) 6-1 against Leylah Fernandez, booking a clash against Romania's Sorana Cirstea after she won 6-3 6-1 against fellow unseeded competitor Bernarda Pera.
Karolina Muchova kick-started a great day for the Czech Republic representatives as she got the better of Italy's Martina Trevisan 6-4 3-6 6-4, and Marketa Vondrousova kept it going with a 7-6 (7-5) 6-4 victory over world number four Ons Jabeur.
Reigning Wimbledon champion Elena Rybakina is shaping up as a threat to win it all, yet to drop a set this week following her 6-3 7-5 triumph over Paula Badosa.
The French top seed looked to be in trouble as Belgian Van Uytvanck eased to the first set, before Garcia found her feet to come back and overwhelm her opponent 2-6 6-0 6-1.
