Reigning Wimbledon and Indian Wells Open champion Elena Rybakina extended her winning streak to 11 matches with Monday's 6-4 6-3 victory over Elise Mertens in the Miami Open fourth round.

Rybakina, 23, has been one of the most in-form talents in the sport this year, with her only two losses since the start of the Australian Open coming in three-setters against Aryna Sabalenka and Beatriz Haddad Maia.

The Kazakhstan representative produced 10 aces against Mertens on her way into the quarter-finals, becoming the first player this WTA season to finish with at least 10 aces in three consecutive matches.

She will look to keep her sparkling form alive when she meets Martina Trevisan for a spot in the semi-finals, after the Italian got the better of Latvia's Jelena Ostapenko 6-3 6-3.

Sabalenka showed why she is the top remaining seed after Iga Swiatek's withdrawal, beating 16th seed Barbora Krejcikova 6-3 6-2. Krejcikova was one of two players this season to beat Sabalenka – with Rybakina the other – and by avenging that defeat the Belarusian improved her record in 2023 to 20-2.

America's top hope Jessica Pegula needed only 79 minutes to eliminate Magda Linette 6-1 7-5, winning the first five games of the match to set the tone early, and she will now meet Russia's Anastasia Potapova in the quarters.

Potapova finished with just one ace compared to Qinwen Zheng's nine, but she showed enough guile to overcome the Chinese international's power advantage.

Romania's Sorana Cirstea kept her great run going with a 7-6 (7-3) 6-4 triumph over Marketa Vondrousova, making it eight wins from her past nine matches, and Bianca Andreescu was forced to retire through injury while down a set 7-6 (7-0) 0-2 against Ekaterina Alexandrova.

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.

Top 10 seeds Ons Jabeur, Caroline Garcia and Maria Sakkari were all eliminated in a day of upsets in the Miami Open second round on Friday.

Qualifier Varvara Gracheva earned her first career top-five win by beating 2022 Wimbledon and US Open finalist Jabeur 6-2 6-2 in only 67 minutes.

Fifth seed Caroline Garcia also crashed out, losing 6-2 6-3 to 74th-ranked Sorana Cirstea, having also recently beaten the Frenchwoman at Indian Wells.

Bianca Andreescu came from a set down to beat seventh seed Maria Sakkari 5-7 6-3 6-4 in a match that lasted over three hours.

Andreescu displayed some of the form that saw her lift the 2019 US Open title, fighting back from a set down and proving composed in the big moments.

The Canadian, who is ranked 31st, will take on 2020 Australian Open champion Sofia Kenin in the third round.

Second seed Aryna Sabalenka had few problems against Shelby Rogers, winning 6-4 6-3 in one hour and 17 minutes. Sabalenka will next face 31st seed Marie Bouzkova.

The 2023 Australian Open champion has won 65 main draw matches in WTA-1000 events, which equals Marion Bartoli and Ashleigh Barty at the 30th place since 2009 for the most wins at this level.

Indian Wells winner Elena Rybakina beat Anna Kalinskaya 7-5 4-6 6-3, and Petra Kvitova eased past compatriot Linda Noskova 6-3 6-0.

Ninth seed Belinda Bencic dropped just two games as she cruised past Leylah Fernandez 6-1 6-1, and will face Ekaterina Alexandrova next as the 18th seed needed three to get past Taylor Townsend.

Veronika Kudermetova was eliminated by Marketa Vondrousova 6-4 6-2, who goes up against Karolina Pliskova in round three after she eased past Wang Xinyu in straight sets.

Maria Sakkari prioritised a pedicure after earning a shot at Australian Open champion Aryna Sabalenka in the Indian Wells Open semi-finals.

Thursday was to be a recovery and re-setting day for Greek Sakkari, one of the stars of the Netflix 'Break Point' series, who is through to her third semi-final of the year.

She booked a last-four spot thanks to a stunning fightback from a set and a break down to Petra Kvitova, but Sakkari's efforts this week in California have left her with bleeding toes.

It is hardly surprising, considering she has taken a long route through to the semi-finals, reeling off four consecutive three-set wins.

Sakkari has lost the first set in three of those four matches but found a way to battle back, but she will want to start strongly against a dialled-in Sabalenka.

After coming through 4-6 7-5 6-1 against Kvitova, Sakkari said in an on-court interview: "I need a pedicure because my feet are bleeding so badly."

Asked about that comment later, she said in a press conference: "It's just my nails. It's not ideal, but nothing bad, like I can properly play and run and everything, but it's not nice."

It sounds far from pleasant, yet Sakkari fights on, aware that despite not playing her top-level tennis so far this fortnight, resilience has pulled her through.

"It is strange, but at the same time, I'm just telling myself, look, you're not playing your best tennis and you're still winning and beating amazing players," Sakkari said.

"By just surviving and just finding ways, eventually I'm sure that my game is going to get better. I really want to see how it's gonna be when I will start feeling good with my game.

"But of course I don't want to say that like I was playing s*** and I won. That's not the case. That's also very bad for the opponent."

Considering Kvitova is a two-time Wimbledon champion and a 29-time singles title winner on tour, Sakkari ranked Wednesday's win as one to log alongside her finest victories.

"For me coming back against her, now that she's playing good, now that she has beaten so many good players, it's a bloody good win," Sakkari said. "The fact I found a way was one of the best comebacks of my life."

Sakkari trails 4-3 in the career head-to-head against Sabalenka despite winning their last two encounters, both at the WTA Finals in each of the past two seasons.

They have not faced each other since Sabalenka became a first-time grand slam champion in Melbourne at the start of the year.

Sakkari was runner-up at Indian Wells 12 months ago, losing to Iga Swiatek in the final, and she has designs on beating Sabalenka to earn another crack at the title match.

Asked about the Belarusian, Sakkari said: "She's an amazing player. I knew that she was gonna win a grand slam. It actually came, and I was very happy for her.

"She's very fun to be around. It's going to be very, very tough, because she's feeling the ball really well."

Australian champion Aryna Sabalenka made light work of sixth seed Coco Gauff in a dominant straight-sets win to clinch her spot in the Indian Wells Open semi-finals on Wednesday.

Sabalenka improved her 2023 season record to 16-1 with a 6-4 6-0 win over the 19-year-old American in only 65 minutes.

The Belarusian will face seventh seed Maria Sakkari in the semi-finals after the Greek edged out 15th seed Petra Kvitova in three sets in the evening quarter-final.

Sabalenka will be tough to beat, however, maintaining her strong season form against Gauff who had little answers despite boasting a 3-1 head-to-head record coming into the clash.

The second seed crushed 18 winners compared to Gauff's 12, while she committed 14 fewer unforced errors across the match.

Sabalenka opened up a 2-0 lead in the first set and maintained that buffer to take the opening frame, before a 25-minute second-set bagel underlined her dominance.

"I feel a little bit different on the court this year," Sabalenka said after the match. "I feel like I'm a little bit different player. I wasn't really focusing on the last matches against her. I was focused on myself."

Sakkari came from behind to defeat two-time Wimbledon champion Kvitova 4-6 7-5 6-1 in two hours and 17 minutes.

The Greek, who finished as last year's Indian Wells Open runner-up, was broken twice in the first set and dropped serve again in the opening game of the second frame, before finding a way to flip the match on its head.

Sakkari broke back for 3-3 in the second set, winning 12 of the final 15 games for victory in an impressive turnaround. All four of Sakkari's matches in Indian Wells this fortnight have gone to three sets.

Top seed Iga Swiatek will be hard top stop in her title defence at the Indian Wells Open after a straight-sets thrashing over Emma Raducanu in Tuesday's last 16.

The Polish world number one eased to victory 6-3 6-1 in one hour and 25 minutes over the 2021 US Open champion, who has enjoyed an improved run this week in California.

Swiatek offered few weaknesses in a strong disciplined display, converting four of 10 break points, including three in a one-way second set.

The three-time major winner won 88 per cent on her first serve while she was impressive on return and able to win the longer rallies. Swiatek hit 22-9 winners while Raducanu made 22-14 unforced errors.

Swiatek will take on Romania's Sorana Cirstea in the quarter-finals, after she upset fifth seed Caroline Garcia 6-4 4-6 7-5 in two hours and 24 minutes.

Reigning Wimbledon champion Elena Rybakina also progressed in that part of the draw, setting up a last-eight clash with unseeded Czech Karolina Muchova.

Rybakina won 6-3 6-0 over qualifier Varvara Gracheva in a similarly strong performance, needing only one hour and 21 minutes.  Muchova beat compatriot Marketa Vondrousova 6-4 6-7 (2-7) 6-4 in two hours and 37 minutes.

Third seed Jessica Pegula was the major casualty of the day's play, going down 6-2 3-6 7-6 (13-11) to 16th seed Petra Kvitova in a dramatic two-hour-and-16-minutes clash.

Pegula had opened up a 5-3 third-set lead and squandered a match point on serve, before two-time Wimbledon winner Kvitova squared it up at 5-5. Kvitova, however, was broken immediately to offer Pegula another chance to serve out the match again, which she was unable to take.

The American generated another three match points in the tie-break but could not convert before the Czech eventually prevailed on her own fourth match point, with the deciding set lasting one hour and 12 minutes.

Kvitova will face seventh seed Maria Sakkari in the quarters after she triumphed in a lengthy clash 6-4 5-7 6-3 over Karolina Pliskova, lasting two hours and 43 minutes.

Second seed Aryna Sabalenka also needed three sets to beat Barbora Krejcikova 6-3 2-6 6-4 in two hours and four minutes. Krejcikova had been responsible for Sabalenka's lone loss this season, in a 15-1 year.

Sabalenka, who won this year's Australian Open, will face sixth seed Coco Gauff who defeated Rebecca Peterson 6-3 1-6 6-4. Gauff won the last four games for victory, having trailed 4-2 in the deciding set.

Third seed Jessica Pegula rallied back from a set down for the second straight match to advance into the final 16 with a 3-6 6-4 7-5 victory over 26th seed Anastasia Potapova.

Potapova won the first set in 39 minutes, claiming the only break of the frame in the sixth game, but Pegula responded by breaking immediately in the second.

Despite squaring the match up, the American trailed 3-1 in the third set, only to fight back again and triumph in two hours and 17 minutes.

Pegula will face 15th seed Petra Kvitova after she won a seesawing three-set contest over 24th seed Jelena Ostapenko, 0-6 6-0 6-4.

Ostapenko won the first six games, before Kvitova won the next 10, only for the Latvian to hit back and claim the next four, squaring up the deciding set at 4-4. But two-time Wimbledon champion Kvitova held her nerve and won the final two games for victory.

World number two Aryna Sabalenka progressed to the final 16 via walkover after her third-round opponent Lesia Tsurenko withdrew.

The 2023 Australian Open champion will take on 2021 French Open winner Barbora Krejcikova after she toppled Wang Xin 6-2 6-7 (1-7) 6-2.

Seventh seed Maria Sakkari secured victory in a two-and-a-half-hour third-round clash with Anhelina Kalinina, winning 3-6 6-2 6-4.

Two-time major runner-up Karolina Pliskova won 6-1 7-5 over Veronika Kudermetova, progressing into the last eight to face Sakkari.

Sixth seed Coco Gauff, who turns 19 on Monday, eased past 54th-ranked fellow teenager Linda Noskova 6-4 6-3 in one hour and 19 minutes.

Sweden's Rebecca Peterson continued her resurgent form with a 3-6 6-3 6-1 win over Jil Teichman, setting up a clash with Gauff.

Aryna Sabalenka showed exactly why she is ranked second in the world as she dominated her opening match of the Indian Wells Open on Friday against Evgeniya Rodina.

Belarus' Sabalenka needed just 66 minutes to defeat the Russian 6-2 6-0, taking advantage of her first-round bye to book her spot in the third round against Ukraine's Lesia Tsurenko.

Tsurenko had to come from behind against the in-form Donna Vekic, fresh off her Monterrey Open title last week, but that big effort may have had the Croatian with heavy legs as she ran out of steam 2-6 6-2 6-2.

It was a strong day for the Ukranians as 27th seed Anhelina Kalinina beat the Czech Republic's Linda Fruhvirtova 4-6 6-4 7-5, and she will next face Greece's Maria Sakkari.

Sakkari, the seventh seed, had to deal with adversity after a poor first set against Shelby Rogers, coming back to win 2-6 6-4 6-0.

Olympic gold medallist Belinda Bencic lost her Swiss showdown against Jil Teichmann 3-6 6-3 6-3, while Veronika Kudermetova got the better of her Russian compatriot Anna Blinkova 6-3 6-4.

The second-highest ranked American in the field, Coco Gauff, had no issues dispatching Spain's Cristina Bucsa 6-2 6-4. But it was tougher work for America's top hope Jessica Pegula as she was pushed all the way by recent Merida Open champion Camila Giorgi, before prevailing 3-6 6-1 6-2.

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 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. 

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.

Dan Evans helped Great Britain reach the last eight of the inaugural United Cup as his 6-3 1-6 6-3 win over Albert Ramos-Vinolas decided the team's Group D tie against Spain.

Rafael Nadal's shock defeat to Cameron Norrie – coupled with Katie Swan's win against Nuria Parrizas-Diaz – put Spain 2-0 down in the best-of-five tie ahead of Sunday's action.

World number 13 Paula Badosa put them back into contention with a hard-fought 6-7 (6-8) 7-6 (7-5) 6-1 win against Harriet Dart, but Evans gave Britain an unassailable lead by battling past Ramos-Vinolas, recovering from a dismal second set.

Having topped Group D, Britain will face the Croup C winners – the United States, Germany or the Czech Republic – for a semi-final place on Wednesday.

Meanwhile, Hubert Hurkacz doubled up to help Poland past Kazakhstan, teaming up with Iga Swiatek in the mixed doubles after beating Alexander Bublik.

Hurkacz beat Bublik 7-6 (8-6) 4-6 6-3 in just over two hours before Magda Linette overcame Zhibek Kulambayeva 6-2 6-1.

With Poland's first win in the competition secure, world number one Swiatek helped Hurkacz put the icing on the cake with a 6-3 6-4 victory against Kulambayeva and Grigoriy Lomakin.

The Czech Republic also enjoyed a fruitful day as two-time Wimbledon champion Petra Kvitova downed Laura Siegemund in straight sets to seal the team's win against Germany, but Casper Ruud was less fortunate, with Norway losing their tie against Brazil despite his success against Thiago Monteiro.

Maria Sakkari sealed victory for top-seeded Greece over Bulgaria in the United Cup with a straight sets win over Viktoriya Tomova.

Team-mates Stefanos Tsitsipas and Despina Papamichail had already won their matches on Thursday, and Sakkari's 6-3 6-2 triumph gave Greece an unassailable 3-0 lead.

Michail Pervolarakis was defeated by Dimitar Kuzmanov in the final singles match between the nations, but Tsitsipas and Sakkari teamed up to earn Greece a 6-4 6-4 success in the doubles encounter to end on a high.

World number 16 Matteo Berrettini helped Italy topple Brazil by overcoming Thiago Monteiro 6-4 7-6 (9-7).

That gave Italy a 2-1 lead, and Lucia Bronzetti finished the job by demolishing Laura Pigossi in straight sets, with Brazil powerless to overturn the deficit despite Berrettini and Camilla Rosatello's defeat in the doubles match.

US Open semi-finalist Frances Tiafoe clinched a win for the United States over the Czech Republic after opponent Tomas Machac retired with an ankle injury with the score at 6-3 2-4.

Petra Kvitova had defeated Jessica Pegula 7-6 (8-6) 6-4 in the third singles match to give Czech Republic hope, but Tiafoe's win settled the contest before Pegula and Taylor Fritz joined up for success in the doubles.

Great Britain were 3-2 victors over Australia despite a pair of defeats on day two in Sydney.

Cameron Norrie's triumph over Nick Kyrgios' replacement Alex De Minaur on day one had helped Great Britain to a 2-0 lead over the hosts, and Harriet Dart prevailed over Maddison Inglis to wrap up the victory.

Dan Evans was then beaten 6-3 7-6 (7-3) by Jason Kubler before Dart and Jonny O'Mara fell to defeat in the doubles, but Great Britain's strong start saw them through.

France and Switzerland completed 5-0 sweeps of Argentina and Kazakhstan respectively, with Caroline Garcia winning both her singles and doubles matches in straight sets while Stan Wawrinka saw off Alexander Bublik 6-3 7-6 (7-3).
