Last week's Indian Wells Open champion Elena Rybakina has extended her winning streak to 10 matches after defeating Paula Badosa 3-6 7-5 6-3 in Saturday's Miami Open third round.

Kazakhstan's Rybakina, who is also the reigning Wimbledon Champion and Australian Open finalist, got the better of Badosa for the second time during her current run, also eliminating her from Indian Wells. 

The 23-year-old has to be considered one of the favourites to go all the way, having knocked off world number one Iga Swiatek and world number two Aryna Sabalenka to lift the trophy in California.

Rybakina will meet Belgium's Elise Mertens in the fourth round after she beat Croatia's Petra Martic 6-4 6-3.

Meanwhile, the biggest upset of the day was delivered by Russia's Anastasia Potapova, bouncing sixth seed Coco Gauff 6-7 (8-10) 7-5 6-2.

Potapova, who has never won a tournament above the WTA 250 level, will face China's Zheng Qinwen for a spot in the quarter-finals after her three-hour 5-7 7-6 (7-5) 6-3 triumph over Liudmila Samsonova.

Latvia's Jelena Ostapenko, the 24th seed, eliminated Brazilian 13th seed Beatriz Haddad Maia 6-2 4-6 6-3, while 20th seed Magda Linette of Poland knocked out Belarusian 14th seed Victoria Azarenka 7-6 (7-3) 2-6 6-4.

Unseeded American Clare Liu went down 4-6 7-5 6-4 against Italy's Martina Trevisan, but third seed Jessica Pegula will continue to fly the flag for the United States after advancing 6-1 7-6 (7-0) in her all-American showdown with Danielle Collins.

Jessica Pegula and Coco Gauff headlined a great day for the Americans at the Miami Open as they both advanced into the third round on Thursday.

Pegula, who is the second-highest seed remaining in the field after Iga Swiatek's withdrawal, had no issue dispatching Canada's Katherine Sebov 6-3 6-1 in just 66 minutes.

Gauff, the six seed, followed suit as she raced to a 6-4 6-3 win over Canadian Rebecca Marino in just 73 minutes.

Florida's own Danielle Collins thrilled her hometown crowd with a 7-6 (7-3) 6-2 triumph against Bulgaria's Viktoriya Tomova, and rising 22-year-old talent Clare Liu made it a perfect 4-0 sweep for the USA representatives by defeating Julia Grabher 6-4 6-3.

Last week's Indian Wells Open champion Elena Rybakina was made to work in her 7-5 4-6 6-3 win over Anna Kalinskaya, while an even more gruelling effort was required in Paula Badosa's two-hour-and-52-minute 7-6 (7-2) 4-6 6-2 result against Laura Siegemund.

The top seed to fall on Thursday was eighth seed Daria Kasatkina, as she won the first set before going down 4-6 6-2 6-2 against Elise Mertens.

Liudmila Samsonova, the 12th seed, made light work of Viktorija Golubic in a 6-1 6-1 drubbing, and 22nd seed Jelena Ostapenko prevailed 6-3 6-4 against Mirjam Bjorklund.

Ostapenko will next play 13th seed Beatriz Haddad Maia after she won a strange back-and-forth contest 7-6 (7-4) 0-6 6-0 over Tereza Martincova.

Former US Open champion Emma Raducanu enjoyed a winning return to the court on Thursday as she defeated Danka Kovinic 6-2 6-3 in the first round of the Indian Wells Open.

It was the 20-year-old's first match since her second-round exit in January's Australian Open, and she had to respond to some early adversity after Kovinic broke her opening service game.

But the Brit answered right back, rattling off four games in a row to take control of the first set, and the second frame was nearly a carbon copy, falling down 2-0 before putting together five unanswered games of her own.

Meanwhile, world number 31 Danielle Collins – the highest ranked player in the draw to not receive a seed – was a surprise early elimination as Hungary's Dalma Galfi got the better of her 6-4 6-4. As a reward, Galfi will meet world number five Caroline Garcia in the second round.

Nuria Parrizas-Diaz set up an all-Spanish second-round clash with Paula Badosa after beating Italy's Elisabetta Cocciaretto 6-3 7-5, but fellow Spaniard Rebeka Masarova fell short 4-6 6-4 6-4 against American Peyton Stearns.

It was a great day for the Czech Republic representatives, with Katerina Siniakova earning a 7-5 6-4 over Julie Niemeier, Marketa Vondrousova dominating Rebecca Marino 6-2 6-2, and Karolina Muchova completing the hat-trick against Yulia Putintseva 6-3 4-6 6-4.

As good of a day as it was for the Czechs, it was just as poor for the Italians, with Lucia Bronzetti falling 7-5 4-6 6-3 to Bernarda Pera and Jasmine Paolini eliminated 7-5 6-1 at the hands of Tatjana Maria, joining Cocciaretto on an early flight home.

Marta Kostyuk is through to her first WTA singles decider after defeating Danielle Collins 6-4 6-3 in Saturday's ATX Open semi-final.

Ukraine's Kostyuk prevailed in a closely contested battle against the highest seed remaining in the field, taking the only break of the first set after saving four Collins break points the game prior.

The two women traded breaks to begin the second set, but the 20-year-old Kostyuk was too strong down the stretch, winning five of the final six games.

It will also be the first WTA-level final for her opponent, with unseeded 22-year-old Russian Varvara Gracheva overcoming American Katie Volynets 6-4 5-7 6-4.

The two-and-a-half-hour clash was tight all the way through, with Gracheva only narrowly edging the total point count 101-94.

Meanwhile, down south of the border at the Monterrey Open, world number five Caroline Garcia won her semi-final against Elise Mertens 6-3 6-4.

The reigning WTA Finals champion will have a chance to collect the 12th singles title of her career, and her first of the season, when she meets Croatia's Donna Vekic in the final.

Vekic, the third seed, emerged the 7-5 6-2 victor against China's Zhu Lin, continuing a red-hot run of form that has seen her win 13 of her past 15 matches dating back to New Year's Eve.

Caroline Garcia is now three wins away from her first title of 2023 after defeating Nuria Parrizas-Diaz 6-3 6-2 in Thursday's second round of the Monterrey Open.

France's Garcia, the world number five and top overall seed, needed just 63 minutes to see off her Spanish challenger. She controlled the contest with her serve, taking the ace count eight to two while winning 75 per cent of her total service points (33-of-44).

She will now face Egypt's Mayar Sherif in the quarter-final after the seventh seed survived a tough 3-6 7-6 (8-6) 6-4 test from China's Wang Xinyu.

Fourth seed Elise Mertens emerged the 6-3 3-6 6-2 victor against Romania's Elena-Gabriela Ruse, while rising 22-year-old Italian Elisabetta Cocciaretto prevailed 7-6 (7-5) 7-6 (7-3) against Germany's Tatjana Maria.

North of the border in Austin's ATX Open, Danielle Collins ripped off a 67-minute 6-1 6-1 drubbing of Caty McNally to advance to the quarter-final.

Collins will meet Russia's Anna Kalinskaya next after the 24-year-old's convincing 6-3 6-1 victory over veteran CoCo Vandeweghe.

Eighth seed Marta Kostyuk is one of only three seeded competitors remaining after storming home in a 6-3 3-6 6-0 battle with Madison Brengle, and Germany's Anna-Lena Friedsam won the longest match of the day in a 7-5 6-7 (2-7) 7-6 (10-8) three-hour war of attrition against 18-year-old Russian Erika Andreeva.

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 continued her impressive run of form this season with a straight-sets win over Viktoriya Tomova in the opening round of the Qatar Open.

The seventh seed triumphed at the Abu Dhabi Open last week to add to her Adelaide International 2 success from January and is now seeking another title in Doha.

Bencic eased to a 6-0 6-1 win against Bulgarian qualifier Tomova and will face two-time tournament winner Victoria Azarenka for a place in the quarter-finals.

Maria Sakkari also advanced on Tuesday, overcoming Zheng Qinwen 6-2 3-6 6-3, as did fellow seeded player Daria Kasatkina with a 7-6 (7-5) 6-2 win against Rebecca Marino.

Zheng may have suffered an early exit, but last season's WTA Newcomer of the Year produced the shot of the tournament with a winning tweener en route to taking the second set.

Petra Kvitova, another two-time winner in Qatar, defeated Zhang Shuai 7-5 6-2, while Danielle Collins beat Elise Mertens 6-4 7-6 (8-6) and will now face top seed Iga Swiatek.

Second seed Jessica Pegula will take on Jelena Ostapenko, meanwhile, after the Latvian proved too strong for Madison Keys in a 7-5 6-2 victory.

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. 

Danielle Collins needed seven match points to defeat Jil Teichmann at the Adelaide International 2 but ultimately progressed to the quarters.

Collins, seeded 10th, had victory in her grasp after reeling off four straight games in the second set.

Yet she was unable to get over the line at the first six times of asking, initially failing to serve out the win before Teichmann saved five match points.

Collins, though, regained momentum in the tie-break to win 6-3 7-6 (7-2).

World number nine Veronika Kudermetova is next up for Collins, having received a walkover to the last eight.

Caroline Garcia, the highest-ranked player left in the tournament, overcame Katerina Siniakova 6-3 3-6 7-5, but was made to work for her win.

Having been pegged back in the second set, Garcia seemed well set to push for victory when she went 3-1 up in the decider, but Siniakova broke and then held her serve to restore parity.

A tie-break looked likely until Garcia converted the third break point of a thrilling 12th game to claim victory.

Barbora Krejcikova, the 2021 French Open champion, was ousted by fifth seed Daria Kasatkina, who cruised through 6-2 7-5.

World number eight Kasatkina will take on two-time Wimbledon champion Petra Kvitova for a place in the last four.

Belinda Bencic also progressed, as did Paula Badosa and Beatriz Haddad Maia.

Anna Blinkova caused an upset at the Hobart International, dispatching top seed Marie Bouzkova 7-5 6-4.

Fifth seed Anhelina Kalinina is the favourite after Bouzkova's exit and a tie with 2019 champion Sofia Kenin is her reward for a win over Tatjana Maria. 

Petra Kvitova defeated Elena Rybakina in the pick of the first-round matches at the Adelaide International 2 on Monday.

Two-time Wimbledon winner Kvitova hit 21 winners to 12 unforced errors on her way to a 6-3 7-5 win against reigning SW19 champion Rybakina in a match lasting 87 minutes.

Belinda Bencic, a defeated finalist in this tournament in 2021, also advanced with a 6-3 6-4 win against former world number one Garbine Muguruza to maintain her positive form.

Fellow seeded players Beatriz Haddad Maia and Danielle Collins beat Sorana Cirstea and Karolina Pliskova respectively to book their places in the last 16.

At the Hobart International, favourite Marie Bouzkova saw off Jacqueline Cristian 7-6 (7-2) 6-3, while Lauren Davis defeated Sloane Stephens 6-2 6-2 in an all-American clash.

Linda Noskova produced the biggest win of her career as she defeated Daria Kasatkina 6-3 6-7 (2-7) 6-3 at the Adelaide International on Monday.

The 18-year-old Czech was impressive against the third seed as she recorded her first win against anyone in the top 30 of the world rankings.

Fourth seed Veronika Kudermetova eased past Amanda Anisimova in just an hour and 15 minutes, winning 6-3 6-0, while Liudmila Samsonova will face second seed Aryna Sabalenka in the next round after coming from a set down to beat Zhang Shuai 5-7 6-3 6-0.

Irina-Camelia Begu and Elena Rybakina also both came from behind to secure wins, with the latter beating fifth seed Danielle Collins to set up a last-16 clash against Ukrainian Marta Kostyuk, who beat Jaimee Fourlis 6-1 3-6 6-4.

At the ASB Classic in Auckland, 42-year-old Venus Williams comfortably overcame her 21-year-old opponent Katie Volynets 7-6 (7-4) 6-2, and will play China's Zhu Lin next after she eliminated sixth seed Madison Brengle 4-6 7-6 (8-6) 6-4.

Third seed Leylah Fernandez beat Brenda Fruhvirtova 6-1 6-1 to set up a last-16 tie with Julia Grabher after she defeated Tereza Martincova in three sets.

Eighth seed Rebecca Marino is through after beating Dalma Galfi in straight sets and will now face Ysaline Bonaventure, who eventually put away Caty McNally 5-7 6-4 6-4.

Viktoria Kuzmova led fourth seed Bernarda Pera 5-4 in the opening set when rain stopped play for the day.

American teenager Coco Gauff showed why she deserves to be at this year's WTA Finals with a commanding 6-0 6-3 victory over Martina Trevisan at the Guadalajara Open.

The fifth seed clinched her maiden spot at the season-ending WTA Finals on Wednesday and backed that up by securing her third WTA 1000 quarter-final on Thursday.

Gauff reeled off the first nine games of the match against Trevisan, where she triumphed in one hour and one minute. The 18-year-old came under pressure from Trevisan, who generated nine break points for the match but Gauff saved all bar one of them.

World number one Iga Swiatek (47) is the only player to have won more matches this year in straight sets than Gauff (32).

Gauff will face Victoria Azarenka in the quarter-finals after the Belarusian toppled 13th seed Madison Keys 6-4 6-7 (4-7) 6-1 in two hours and 13 minutes.

Two-time Australian Open winner Azarenka swept aside Keys in 32 minutes in the third set after a titanic battle in the opening two frames, winning 26 of the 37 final-set points. Azarenka's quarter-final appearance is her 34th since 2009, with only four players having more during the span; Agnieszka Radwanska (42), Simona Halep (39) and Caroline Wozniacki (36).

Third seed Jessica Pegula advanced to the last eight with a 6-4 6-4 victory over former US Open champion Bianca Andreescu. 

The American, who survived three match points against Elena Rybakina on Wednesday, trailed early against the Canadian but took control of the match. Pegula will face Sloane Stephens in the quarter-finals after she toppled 2022 US Open semi-finalist Caroline Garcia 7-6 (8-6) 7-5.

On the day her WTA Finals berth was confirmed, seventh seed Daria Kasatkina lost 6-2 2-6 6-3 to Anna Kalinskaya in two hours and 14 minutes.

Fourth seed Maria Sakkari fought back to win 5-7 6-3 6-3 over 14th seed Danielle Collins, while Marie Bouzkova copped a bagel before triumphing 0-6 7-5 6-3 over Liudmila Samsonova.

Sakkari will next meet eighth seed Veronika Kudermetova who beat Jelena Ostapenko 6-4 6-4. Bouzkova will take on Kalinskaya in the last eight.

It was a great day for the highly ranked Americans at the Guadalajara Open on Wednesday, headlined by world number five Jessica Pegula and her 2-6 6-3 7-6 (10-8) comeback win over Wimbledon champion Elena Rybakina.

Pegula, who is now locked into the top-eight and therefore will qualify for the WTA Finals, struggled to win points on her serve in the opening set, but raised her 57 per cent success rate up to 69 per cent in the second set, and 66 per cent in the decider.

The American had to come from a break down in the second set to keep her tournament alive, and she will now face Canada's Bianca Andreescu in the third round.

Meanwhile, fellow United States star Coco Gauff was too good for Italy's Elisabetta Cocciaretto, winning 7-6 (7-1) 6-3 to book a third-round clash with another Italian, Martina Trevisan, who earned her way there with a 6-0 4-6 6-3 win over Katerina Siniakova.

The other two seeded Americans were also successful, with 13th seed Madison Keys coming from a set down to defeat Ajla Tomljanovic 3-6 6-4 6-3, and 14th seed Danielle Collins repelled the challenge of Magdalena Frech 6-3 6-4.

There were positive signs for former world number five Eugenie Bouchard, who ended up losing, but showed she still has her talent by taking a set off world number 23 Jelena Ostapenko in a 7-5 2-6 6-1 result.

Russian pair Anna Kalinskaya and Liudmila Samsonova both emerged in three-set outings, with Kalinskaya outlasting Elise Mertens 6-4 0-6 7-5, while Samsonova upset world number four Aryna Sabalenka 6-4 2-6 6-2.

World number 12 Veronika Kudermetova kept her WTA Finals hopes alive with a 6-4 7-5 win over Donna Vekic, and the Czech Republic's Marie Bouzkova ousted Colombia's Camila Osorio 6-3 6-1.

In the late window, Sloane Stephens eliminated Olympic gold medalist Belinda Bencic 6-4 6-4, and top overall seed Paula Badosa retired due to injury after losing the first set 6-2 against Victoria Azarenka.

The top seed in action on Tuesday at the Guadalajara Open made it through her opening match unscathed as Maria Sakkari defeated Marta Kostyuk 6-4 6-4.

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).
