Simona Halep

With temperatures reaching the mid-30s at Melbourne Park, conditions were distinctly uncomfortable for both players on Rod Laver Arena.

The unseeded Muguruza prevailed in a gruelling battle, her 7-6 (10-8) 7-5 success setting up a final showdown against Sofia Kenin on Saturday.

Halep was in charge of each set until being reeled in both times by Muguruza, whose performances had dipped since winning Wimbledon and the French Open earlier in her career.

That grand slam title-winning form was back as Halep, who has also triumphed at the grass-court and clay-court slams, was edged out of the tournament.

"It was very, very hot today and I felt it," Halep said. "It killed me after the first set, in the end of the first set. The sun was strong. I didn't like that much to play in this weather."

Conditions were fractionally below the point on the tournament's heat stress scale at which the roof would have been automatically closed on the stadium court.

"I would love to see the roof closed. But rules are rules. We have to accept it," Halep said.

"The level of energy went down a little bit, and I felt it in the legs. I was not used to it in the last two weeks, we didn't have that much heat. And today I felt the sun a little bit too much. It was not 100 per cent right for me, but it is how it is."

With Australian favourite Ash Barty ousted in the first semi-final, it will be a surprising line-up in the title match.

Romanian Halep said defeat left her "in pain", given the control she held at different stages in the match.

"But life goes on," she said. "I think maybe I could be a little bit more brave in the points that were important. I didn't do that."

Muguruza looked like a player who might dominate the women's tour when she took the 2017 Wimbledon title in some style.

She reached number one in the WTA rankings later that year, but has dropped outside the top 30 since.

"If she can play every day like this, she can be number one, for sure," Halep said. "But it's tough to do that."

Halep knows, having spent 64 weeks at the summit.

"Consistency on tour, it's the most important thing and the toughest one," Halep added. "She's a great champion. She knows how to win grand slams, how to win titles."

A day of upsets left Ons Jabeur, the eighth seed, as the top remaining player in the draw.

Some big names helped deliver the shocks, though, with world number two Sabalenka usurped by two-time Wimbledon champion and 2013 Dubai winner Petra Kvitova in straight sets.

Muguruza did not look like being one of the scalps as her title defence continued against Veronika Kudermetova.

But after taking the first set, the reigning WTA Tour Finals champion went down 3-6 6-4 6-4.

French Open champion Krejcikova, beaten by Muguruza in the final last year, also exited the tournament at the hands of Dayana Yastremska 6-3 7-6 (7-3).

Iga Swiatek let a set lead slip to Jelena Ostapenko, while two-time Dubai champion Elina Svitolina collapsed to lucky loser Jil Teichmann 7-6 (7-0) 6-2.

Jabeur, a winner against Jessica Pegula, was the only seed to win in a ruthless round of 16.

However, her reward in a still stacked quarter-final draw is a meeting with Simona Halep, another who has twice won in Dubai.

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.

That was the message from Professional Tennis Players Association (PTPA) representative Ahmad Nassar, who discussed the damage that the initial decision could have on Halep's career.

The two-time grand slam champion was handed a long ban by the International Tennis Integrity Agency (ITIA) for "intentional" doping offences.

Halep, who won the 2018 French Open and Wimbledon in 2019, repeatedly defended her innocence.

The 32-year-old's appeal was eventually successful earlier this week as the ban that was initially set to last until 2026 was reduced to a nine-month suspension, which was backdated, meaning Halep can return to the court immediately.

"Bittersweet is a good word," Nassar told Stats Perform after the Court of Arbitration for Sport's (CAS) ruling.

"Relief is another word I would use. It's just a relief after a year and a half. The ups and downs of waiting, and then having this initial decision with the four-year ban, and the resulting 116-page decision.

"I worked in US federal court for a year after law school and a lot of times people write decisions to try to bulletproof it on appeal. Other times, it's kind of a pro forma thing, because there's zero chance that's going to get overturned on appeal.

"So when I saw that my first reaction was this is intended to try to bulletproof, throw the proverbial book at her and her team.

"So that on appeal, exactly what ended up happening didn't happen. That's such a sign of how broken the system is, because that shouldn't really be the motivation, the motivation should be what's the right answer?

"I represent all the players, not just Simona. And we go out of our way to say, all the players deserve a clean sport, first and foremost.

"Nobody's more affected by potential doping, especially in tennis, where it's one on one or two on two, than the players. 

"It's a win in a fairly technical sense. They sought to take it from four to six years, which to me is just a jaw-dropper. If you think about that, neither side was happy with the four-year ban, which makes it all the more remarkable that CAS ruled the way they did."

Halep, the former world number one, will make her return at the Hard Rock Stadium in Florida, where action starts on March 17.

Whether she will be able to get back into her stride after a prolonged absence remains to be seen, a sticking point for Nassar.

He added: "Nobody won because you don't get to go back in time. Even if you went back to exactly the day after the nine-month suspension ended, which would have been last summer and let her resume play.

"Still, she went through nine months of assuming the worst, reading the worst, seeing the worst, hearing the worst. It's not only time but also opportunity, it's reputation.

"You take years and years and a whole career, decades to build up your name and you can lose it and your credibility and trust. You can lose it in an instant, and it's hard from that standpoint.

"That really frustrates me. This is not one of those things where you say, 'It's just professional sports, it comes with the territory', because when I look at other sports, this same dynamic does not exist.

"We don't want to call this a real win. She's a former number one, a major champion, with resources and wherewithal and ability, and later in her career, to be able to push back against this real machine that was mobilised against her.

"Most players, 99 per cent of them do not have that and so they take it on the chin, and either retire, or just take the four years and hope that they cut some terrible deal, if that's even in the offing, to settle and move on with their lives.

"That's why the players created the PTPA. It just highlights a huge gap in the system that is going to take years to fill, even on the anti-doping side. It's going to take years.

"I think there's some incremental reforms that hopefully can occur because of this situation that are better for everybody, not just the players. But it's going to be a long-term process."

Osaka had not featured on the red dirt since a third-round exit at the 2019 French Open, missing out on competing on the surface last year due to injury.

This year's Australian Open champion stumbled out of the blocks against Misaki Doi, quickly falling 3-0 behind in the opener, but recovered from the early setback to prevail in straight sets.

The second seed hit 26 winners in a 7-5 6-2 triumph over her compatriot, who has now lost all three of their meetings on the WTA Tour.

"You obviously want to play well against a player that's from the same country," Osaka said.

"I never really know what to expect because I feel like she always plays better when I play against her, so it's a bit tough to manage controlling my emotions. But I think I was able to do it pretty well."

Simona Halep also won in her opener at the event, the third seed racing through the first set before holding off a fightback from Sara Sorribes Tormo in the second.

Halep – who needed 83 minutes to clinch a 6-0 7-5 victory – has been crowned champion twice in Madrid, the first time coming in 2016 before she returned a year later to successfully defend the title.

Aryna Sabalenka wasted little time in seeing off the challenge of Vera Zvonareva, the fifth seed producing 37 winners in a 6-1 6-2 win, her first ever in the event.

Maria Sakkari found the going much tougher before eventually ousting Amanda Anisimova, losing the first seven games in a row before rallying for a 0-6 6-1 6-4 triumph.

Daria Kasatkina was also pushed in her opener, with a 4-6 6-4 7-6 (7-1) win over Irina-Camelia Begu taking just over three hours.

Karolina Pliskova had to go the distance after falling a set behind against Coco Gauff, while two-time finalist Victoria Azarenka came out on top in a deciding set against Ekaterina Alexandrova.

In the final match on a busy day, Jennifer Brady won 6-2 6-4 in an all-American clash with Venus Williams.  

Second seed Osaka was playing just her second match on clay since the 2019 French Open due to injury issues and became the latest big name to fall at the hands of Muchova.

The world number 20, who had already defeated two top-five players this season, prevailed 6-4 3-6 6-1 in a time of one hour and 49 minutes in the Spanish capital.

Osaka has now lost two of her last three matches, having been eliminated from the Miami Open quarter-finals by Maria Sakkari at the end of March.

"I think today for me it was quite different from the last time I lost in Miami, and I actually think I played much better here, so I'm very happy about that," Osaka said.

"I think what I can take away from this is that I tried my best throughout the entire match. I think tennis-wise, I felt I was too defensive in the first set.

"I wouldn't say I’m happy that I lost, but I think I learned a lot. So that's all I can hope for."

Two-time champion Halep has yet to drop a set in this year's tournament after seeing off unseeded opponent Zheng 6-0 6-4.

Halep took nine games in a row at the start of the match but, like in her opening-round win over Sara Sorribes Tormo, she had to hold off a late surge from her opponent to advance.

Next up for Halep is a last-16 showdown with Elise Mertens, who beat Elena Rybakina 7-6 (7-4) 7-5 in the last of Sunday's matches.

Fifth seed Aryna Sabalenka safely advanced earlier in the day thanks to a 6-3 6-3 win against Daria Kasatkina, while Sakkari beat Anett Kontaveit 6-3 6-1.

Sabalenka was on course to face Victoria Azarenka for a place in the quarter-finals, but the Belarussian withdrew from her match with Jessica Pegula because of a back injury.

Elsewhere, Jennifer Brady, who knocked out fellow American Venus Williams in the first round, eased past Jelena Ostapenko 6-2 6-1.

Brady faces a tricky test in the next round with Anastasia Pavlyuchenkova, who defeated sixth seed Karolina Pliskova 6-0 7-5, seeking another scalp.

Osaka won the first three games of the match to jump out to an early lead, securing the set with a double-break before breaking early in the second to cruise to a 6-2 6-3 win.

The story of the match was Osaka's ease in winning points against Kerber's serve, winning 41 per cent (15/37) of Kerber's successful first serves, while the German could only win 11 per cent (3/27) in the same category.

Britain's top-ranked woman Emma Raducanu suffered another early exit, on the wrong end of Katerina Siniakova's comeback 3-6 6-4 7-5 win.

Ostapenko, who is the world number 21, stunned Halep in their first meeting in the 2017 Roland Garros final to win her first Grand Slam before the Romanian exacted revenge in Beijing later that season.

In their first meeting since that last-four clash, Halep raced out the blocks to wrap the first set in just 27 minutes as she converted both break-point opportunities to take an early lead.

However, Ostapenko responded emphatically in the following set, claiming a 3-0 advantage before eventually levelling things up after a one-sided tie-break separated the pair in the second.

Ostapenko carried her momentum in the deciding set as she made a blistering start, with Halep unable to win a single game as the 24-year-old secured victory in an hour and 36 minutes.

Kudermetova awaits the Latvian in the final after Marketa Vondrousova was forced to withdraw from her last-four match due to a right adductor injury.

The pair have not met before on the WTA Tour but boast identical records at the start of the 2022 season, with both winning eight of their matches and losing three.

Ostapenko won as a wildcard in 2021, and the world number 14 confirmed her place in this year's showdown by overcoming Camila Giorgi on Friday.

She is the first female player to reach back-to-back finals in Eastbourne since Caroline Wozniacki in 2017 and 2018.

The Latvian, who is also going to compete for the doubles title, prevailed 6-2 6-2 and will now go up against Kvitova. The pair have faced off eight times previously, with each player winning four matches.

It is Kvitova's first appearance in a final in 2022, with the former world number two – and two-time Wimbledon champion – having ended Beatriz Haddad Maia's winning streak.

Haddad Maia won in Birmingham last week and Nottingham the week before, but her run came to an end at 12 matches, with Kvitova triumphing 7-6 (7-5) 6-4.

"For me, a final after almost a year [without one] will be great, so I’m glad already," said Kvitova, who was a runner-up at Eastbourne in 2011 and last reached a final on grass in Birmingham four years ago.

"Jelena loves to play here, obviously, we saw it, she has a really great game for grass."

Meanwhile, at the Bad Homburg Open, 2019 US Open champion Bianca Andreescu reached her sixth career final courtesy of a walkover against Simona Halep.

The Romanian withdrew from the semi-final clash with a neck injury, which will worry the 2019 Wimbledon champion ahead of the season's third grand slam at the All England Club.

"I am sorry that I had to withdraw today before my semi-final match," Halep said in a statement.

"But unfortunately I woke up this morning with a blocked neck and this is not allowing me to perform to the best of my ability."

Andreescu will face Caroline Garcia, who saved a match point before going on to beat fellow Frenchwoman Alize Cornet 7-6 (11-9) 3-6 7-5 to reach an 11th tour-level showpiece.

Halep on Sunday cited the rise in coronavirus cases in Romania and anxieties around international air travel as her reasons for opting out of the first WTA Tour event since March.

The Romanian's participation in the tournament, which starts on August 3, was in doubt due to new quarantine regulations in Italy.

It was announced on Friday that all visitors who have spent time in Romania or Bulgaria in the past 14 days would need to quarantine for two weeks upon arrival in Italy.

Tournament director Oliviero Palma wrote to Italy's health minister Roberto Speranza to seek an exemption for Halep, and regional assessor of health Ruggero Razza informed the 2019 Wimbledon champion that tennis players would not need to quarantine.

Yet the two-time grand slam champion has delayed her return as she is not ready to head overseas.

She said in a statement released to Stats Perform News on Sunday: "Given the recent rise in COVID-19 cases in Romania and my anxieties around international air travel at this time, I have made the tough decision to withdraw from Palermo.

"I want to thank the tournament director and the Italian ministry of health for all their efforts on my behalf and I wish the tournament a successful week."

Palma was not at all impressed with Halep's withdrawal.

He said: "We found out Halep's decision with great bitterness. Yesterday we were optimistic, and we had informed Halep's staff about the fact that professional players are not obliged to quarantine.

"Nevertheless, Halep's staff only communicated us the final decision, frustrating all our efforts. We are embittered and profoundly disappointed."

Halep was suspended in October 2022 after failing two drug tests following the US Open. The former world number one was initially banned for four years, but a ruling earlier in March by the Court of Arbitration for Sport slashed her suspension to nine months.

The reduced ban means Halep can immediately return to tennis, and the two-time grand-slam winner is set to make her return at the upcoming Miami Open.

When asked whether players in situations like Halep's should receive help to gain back what she has lost during her time away, Nassar told Stats Perform: "Should there be? Absolutely. Will there be? Probably not. For tennis, this is a much broader issue in terms of governance. 

"Think about Simona’s case. Where did this happen, at the US Open? And so you give the Tour the cover to say 'well, it wasn't actually one of our events'. It was, and we didn't admit it. There has to be an answer.

"The net effect is the player gets doubly penalised."

Now 32, Halep will be a wildcard at the Miami Open.

In Nassar's view, that is an opportunity that not every player in a similar situation would be fortuitous enough to receive.

"I don't want to use the word lucky," Nassar explained. "But Simona is unique in the sense that she's already gotten, 24 hours later, a wildcard to Miami, a WTA 1000 event.

"Ninety-nine per cent of players who go through anything like this will not get that. What do they have to do? Well, they have to go play maybe universal tennis events, and then WTA 125s and get back into it. That could take a year, easily.

"Getting back, building your ranking up, getting your points up, getting the money to be able to go back out there. It becomes really overly punitive at that point."

Nassar is hopeful that Halep can return to her top form, which saw her claim French Open and Wimbledon triumphs in 2018 and 2019 respectively.

He added: "What I'll say is this. Athletes who have been unfairly treated often use that as fuel and motivation when they're back. And so I would not be surprised in the least if that was the case.

"But at the same time, I don't want to make light of what Simona and other athletes who go through this type of nightmare have to endure. We definitely wish her all the best."

Nassar also called out some in tennis for their lack of initial support for Halep, continuing: "It's been interesting to see that decision come out.

"It's like everybody is saying 'welcome back' with open arms. And I have to ask myself, where were these people for 17 months?

"The process was not okay. And it's still not okay."

Raducanu celebrated her first WTA Tour win at the expense of Polona Hercog in Cluj on Tuesday and followed that up with a 6-3 6-4 defeat of Ana Bogdan. 

The 18-year-old US Open champion had a first-serve percentage of 69 and won 87 per cent of those points, breaking three times to move into the last eight. 

Third seed Raducanu said: "It's definitely taking me some time to find my feet still. I'm just taking some learnings from every match that I play. I don't think I'm the finished product yet." 

Next up for the Brit is a meeting with fellow teenager Marta Kostyuk after the sixth seed sent Mona Barthel packing with a 6-4 6-4 victory. 

Halep was troubled by a back injury in a 6-4 6-2 success over Varvara Gracheva in her homeland. 

The two-time grand slam champion played through the pain barrier, breaking twice in each set to progress, and could face Raducanu if she beats fellow Romanian Jaqueline Cristian. 

"The back got blocked and the pain is really big," Halep said in the on-court interview. "You cannot really bend much and you cannot move. 

"But sometimes you are used to the pain, I had this before many times, and I just wanted to continue and finish this match. It's good that I won this match, I don't know how." 

Anett Kontaveit, striving to secure a WTA Finals berth, extended her indoor winning run to 12 matches by seeing off Alison Van Uytvanck 6-3 6-4, while Rebecca Peterson knocked Irina Bara out in straight sets. 

In the Courmayeur Open, Jasmine Paolini came out on top 6-4 7-5 in an all-Italian battle with Lucrezia Stefanini and Zhang Shuai got past Wang Xinyu 7-6 (7-5) 6-4. 

The unseeded Donna Vekic also secured a place in the quarter-finals. 

US Open champion Raducanu claimed her first ever regular WTA Tour win in Cluj earlier this week, with the 18-year-old keen to impress in the homeland of her father, but Kostyuk denied her the chance of a dream last-four clash with Halep.

The 19-year-old Ukrainian swept Raducanu aside in just 57 minutes, winning 6-2 6-1 as Kostyuk furthered her own burgeoning reputation in the game by reaching a third semi-final of the year.

Raducanu proved her own worst enemy, her 41 unforced errors more than double Kostyuk's 16, with the latter feeling confident as early as the first game when two double faults helped her break the Briton's serve.

"I don't know how I won the first game, I think that's where everything started," Kostyuk said. "I somehow won that game and I gained this confidence, like I'm not going to lose this match.

"After that, by the fifth game maybe, I figured out how to play her – today. Maybe next time I play it's going to be different tactics."

Top seed Halep enjoyed a similarly straightforward victory as she lost just two games en route to a 6-1 6-1 win over Romanian compatriot Jaqueline Cristian, a particularly impressive feat given she had been suffering with a back injury this week.

That success preserved Halep's 100 per cent record against fellow Romanians.

On the other side of the draw, second seed Anett Kontaveit was also an impressive winner as she disposed of Anhelina Kalinina 6-1 6-3 in just over an hour. Kontaveit has won 24 of her last 26 matches and will be the firm favourite against unseeded Rebecca Peterson, who beat Lesia Tsurenko 6-2 3-6 6-3.

At the Courmayeur Open in Italy, third seed Liudmila Samsonova cruised into the semis thanks to a swift 6-1 6-2 demolition of Anna Kalinskaya. She will meet Clara Tauson – seeded fifth – after the Dane came through a more gruelling 3-6 6-4 6-2 win over Ann Li.

The other semi will be contested by Donna Vekic and Jasmine Paolini, who were straight-sets winners over Wang Xinyu and Dayana Yastremska, respectively.

Raducanu, who was the surprise US Open champion in September after not dropping a set throughout the tournament, appeared at just her fourth tour-level tournament and came to Cluj as third favourite.

The 18-year-old had lost opening-round matches at previous events in Nottingham, San Diego and Indian Wells.

However, world number 23 Raducanu finally recorded her first victory as she overcame a first-set scare to triumph over Hercog 4-6 7-5 6-1.

In the opening match of Tuesday's fixtures, sixth seed Marta Kostyuk cruised past Bernard Pera 6-3 6-4 to secure her last-16 berth.

Irina-Camelia Begu, ranked one behind Kostyuk for the tournament, did not enjoy similar fortunes as Romanian compatriot Irina Bara triumphed 7-6 (7-2) 0-6 6-4.

Jaqueline Cristian survived a marathon slog against Kaja Juvan as she came from a set down to win 3-6 7-6 (10-8) 7-6 (7-3) and book a second-round meeting with Ajla Tomljanovic.

Number one seed Simona Halep – who departed at the quarter-final stage of the Kremlin Cup last week – plays her first game on home turf on Wednesday against Elena-Gabriele Rusa and could meet Raducanu in the semi-final stages.

Meanwhile, Liudmila Samsonova, the third favourite at the Courmayeur Open, cruised past Stephanie Wagner 6-3 6-0 while seventh seed Jasmine Paolini comfortably dispatched Martina Di Giuseppe 6-4 6-1.

Shuai Zhang, who is the third seed in Italy, also enjoyed a routine victory as she eased past Jessica Pieri 6-1 6-3 after fourth favourite Petra Martic crashed out 3-6 4-6 to Saisai Zheng.

The Belarussian, who is currently ranked 100th, stunned the 19-year-old Briton 6-2 6-4 in one hour and 25 minutes.

Raducanu had been on a 10-match winning streak coming into her maiden Indian Wells campaign.

"I'm still so new to everything. The experiences that I'm going through right now, even though I might not feel 100 per cent amazing right now, I know they're for the greater good," Raducanu said after the defeat.

"I mean, I'm 18 years old. I need to cut myself some slack."

Raducanu, who did not drop a set during her US Open run, appeared in control early after winning the opening six points, but Sasnovich claimed the first break in the third game.

Unforced errors proved costly for Raducanu as the clean-striking Sasnovich capitalized to win the first set, before opening the second set with another break.

Raducanu responded with an immediate break back and led 4-2 in the second set, before the Belarussian hit back by winning the next four games to topple the British teenager.

"It was a really good match for me. I play really well," Sasnovich said. "I know she just won US Open. I lost there in the first round. But I tried to go on court, I tried to enjoy. I did everything right."

FORMER WINNER HALEP PROGRESSES

Sasnovich will face two-time Grand Slam winner Simona Halep in the third round after the Romanian defeated Marta Kostyuk 7-6 (7-2) 6-1 in one hour and 33 minutes.

The 11th seed, who split with long-time coach Darren Cahill last month amid an injury-disrupted year, was down a break early before working her way back and dominating the tiebreak.

Halep broke twice in a more controlled second set to claim victory in her 10th appearance at Indian Wells.

"I missed a lot playing tennis at this level this year because I've been injured and many months, I couldn't play matches," said Halep, who won at Indian Wells in 2015. "I came here a little more aggressive than normal and I'm trying to improve my game and myself."

KVITOVA CRUISES AS TOP SEEDS WIN

Two-time major winner Petra Kvitova eased into the last 32 with a 6-2 6-2 triumph over Arantxa Rus from the Netherlands.

Seventh seed Kvitova set up a showdown with two-time Australian Open champion Victoria Azarenka after she beat Magda Linette 7-5 3-0 in a walkover. Kvitova leads Azarenka 5-3 in head-to-head battles.

Second seed Iga Swiatek dominated Croatian Petra Martic 6-1 6-3 to seal her passage into the third round, while fourth seed Elina Svitolina got past Teresa Martincova 6-2 7-5.

Beaten 2021 US Open finalist Leylah Fernandez triumphed over experienced Frenchwoman Alize Cornet 6-2 6-3 and will play ninth seed Anastasia Pavlyuchenkova in the third round after she easily accounted for Madison Keys 6-3 6-1.

Sabalenka could not quite hit her peak form against Linette, but the world number two nevertheless got the job done after going the distance.

The Belarusian is hunting a record-equalling third title in Madrid, where she is the reigning champion, though she has not won back-to-back matches at a tournament since winning the Australian Open.

"It's not about being confident," Sabalenka said. "It's about how much you're ready to do to get it. It's about the hard work and to be ready, be ready for the big fights. I feel like confidence is not going to help you in those big matches. It's about staying there and fighting for it."

Data Debrief

Sabalenka (70 per cent, 56-24) is now one of five active players since 2020 to hold a winning percentage of 70 per cent or higher at WTA-1000 events.

Iga Swiatek, Simona Halep, Elena Rybakina and Jessica Pegula are the other players to feature on that list.

Kontaveit went into Sunday's final knowing victory over top seed Halep would earn her the last place in the season-ending tournament in Guadalajara.

The Estonian duly denied Ons Jabeur a WTA Finals spot, beating Romanian home favourite Halep 6-2 6-3 in Cluj.

Second seed Kontaveit has now come out on top in 10 consecutive matches, having won the Kremlin Cup last weekend, and this was her fourth title of a stellar season.

Halep had not dropped a set in her previous three meetings with Kontaveit, but the former world number one was soundly beaten to miss out on a fourth title on home soil – five years after her last in Bucharest.

The 25-year-old Kontaveit took her run to 26 victories in her last 28 matches, winning 70.6 per cent of points behind her first serve to Halep's 44.1 per cent.

Kontaveit broke three times in a one-sided first set and fought back from 2-0 down in the second to continue her brilliant run.

Halep has not won a title since September 2020, having been unfortunate with injuries this year.

Rybakina won the first set comfortably before the Russian hit back for a remarkable turnaround win, 1-6 6-2 6-0 in one hour and 40 minutes.

Seventh seed Kasatkina was the runner-up at last year's Silicon Valley Classic and found her groove to break her Rybakina six times in the second and third sets.

Rybakina sent down three of her four aces for the match in the first set, but Kasatkina adjusted to her serve and won 52.1 per cent return points for the match.

Eighth seed Karolina Pliskova fought back from a slow start to get past Katie Boulter 1-6 7-6 (7-5) 6-3, despite 16 double faults.

American Amanda Anisimova overcame compatriot Ashlyn Krueger 6-2 7-6 (7-5). US pair Madison Keys and Taylor Townsend were also winners.

Third seed Simona Halep and top seed Jessica Pegula were both among the winners in the first round at the Citi Open in Washington DC.

Two-time major winner Halep cruised past Spanish qualifier Cristina Bucsa 6-3 7-5 in one hour and 20 minutes.

Halep, playing her first match since her Wimbledon semi-final loss to Rybakina, fired 19 winners but also 33 unforced errors.

Defending champion Pegula made light work of countrywoman Hailey Baptiste 6-2 6-2 in 73 minutes.

Pegula will face unseeded Australian Daria Saville, who won in three sets over Mirjam Bjorklund, while sixth seed Kaia Kanepi will meet China's Zhu Lin after both won on Monday.

Fifth seed Elise Mertens was a first-round casualty, going down 7-6 (7-4) 6-4 to Ludmilla Samsonova, while Croatian Donna Vekic knocked off seventh seed Mayar Sherif 6-4 6-1.

Six-time major champion Venus Williams played her first singles match in nearly a year but bowed out 4-6 6-1 6-4 to Rebecca Marino. 

The third seed was on court for just 34 minutes on Thursday as last-16 opponent Anna Kalinskaya was forced to retire through injury at 6-2 1-0 down.

Sakkari has enjoyed a successful year on the WTA circuit, reaching grand slam semi-finals for the first time in her career at the French Open and US Open.

Through to the quarter-finals in the Russian capital, where she will play Simona Halep, the 26-year-old becomes the first Greek woman to qualify for the year-end WTA Finals in Mexico.

Eighth seed Halep beat Veronika Kudermetova 6-1 7-6 (7-4), while world number 35 Marketa Vondrousova also prevailed in straight sets against Ukrainian Lesia Tsurenko.

Elsewhere, Ostrava Open champion Anett Kontaveit is through to her eighth quarter-final of 2021 after defeating Andrea Petkovic 6-1 6-4.

Meanwhile, at the Tenerife Open, fourth seed Camila Giorgi enjoyed a commanding 6-1 6-2 victory over Montenegro's Danka Kovinic.

However, there was no joy for seventh seed Clara Tauson as the Danish teenager went down 7-6 (7-4) 2-6 6-4 against China's Saisai Zheng.

The Greek star is chasing what would be just her second career title at WTA level, but the limited silverware belies her growing reputation: Sakkari has shot up to a career-high seventh in the world rankings during her best season on tour.

Looking to finish with a flourish, both in Moscow and next month at the season-ending WTA Finals, Sakkari scored a 6-4 6-4 victory over former world number one Halep on Friday.

The victory sets up a last-four clash with Ekaterina Alexandrova, after the Russian impressed a home crowd by landing a 6-3 6-4 win against top seed Aryna Sabalenka.

Yet Sakkari was almost reeled in by Halep from the point of victory in the second set, being unable to finish off the match on her own serve after building a 5-1 lead. Halep twice broke back, before dropping her own serve.

"It was a very tough match today," Sakkari said in an on-court interview. "It was the first time I'd played Simona, but I knew what to expect: she makes a lot of balls, more than any other player. I had a tough moment in the second set when I was 5-1 up, but finally, I found a way. I got a little nervous, a little bit tired.

"The last couple of months have been tough, I've been travelling a lot so haven't recovered enough. I just tried harder in the last game and just went for it."

Alexandrova's shock win over Sabalenka gave her a sixth career victory over a top-10 player. Second seed Garbine Muguruza followed Sabalenka out of the tournament, walloped 6-1 6-1 by in-form Estonian Anett Kontaveit, who has won 19 of her last 21 matches on tour, including beating Sakkari in the Ostrava final last month.

Kontaveit's semi-final opponent at the WTA 500 event will be Marketa Vondrousova, who claimed a 6-4 6-2 win over Anastasia Pavlyuchenkova.

At the Tenerife Open, Italian Camila Giorgi is the only seeded survivor in the semi-finals. The Italian fourth seed saw off Arantxa Rus 6-1 6-1, with Frenchwoman Alize Cornet and American Ann Li also among Friday's winners at the WTA 250 tournament.
