Simona Halep blew Paula Badosa away with a Madrid Open masterclass to reach the round of 16 on Saturday.

Second seed Badosa had no answer to the brilliance of Halep in her homeland as the relentless Romanian won 6-3 6-1 at the Caja Magica.

Unseeded two-time grand slam champion Halep took just an hour and 17 minutes to eliminate Badosa, breaking three times in the first set and twice in the second.

Halep, in a new era with Patrick Mouratoglou in her corner, won 84 per cent of points when she landed her first serve in, staying in the hunt to win this tournament for a third time with the French Open on the horizon.

The former world number one will face Coco Gauff for a place in the quarter-finals following the American's 6-1 2-6 6-4 late-night defeat of Yulia Putintseva.

Gauff, the 14th seed, racked up 10 double faults and was pushed all the way by Putintseva, but served out the match after securing a third break in a tight final set.

Ons Jabeur earlier advanced into the third round at the expense of Varvara Gracheva, recovering from a second-set bagel to win 7-5 0-6 6-4.

Jabeur faces a meeting with Belinda Bencic after the Swiss dispatched Karolina Muchova 6-3 4-6 7-5.

Victoria Azarenka came from a set down to beat Tamara Zidansek 3-6 6-1 6-3 to set up a meeting with Amanda Anisimova, who also had to come from behind to dispatch Petra Martic 3-6 6-3 6-2.

Ekaterina Alexandrova and Marie Bouzkova also progressed in the Spanish capital.

Patrick Mouratoglou, the long-time coach of Serena Williams, has confirmed he will now work with Simona Halep.

Mouratoglou began coaching Williams in 2012 and has guided the former world number one to 10 grand slam titles and a further six major finals.

However, the last of those triumphs came in 2017, with Williams still one major success shy of matching Margaret Court's long-standing record of 24.

Williams reached the semi-final of last year's Australian Open, losing to Naomi Osaka, before subsequently going out in the last 16 at Roland Garros.

But the 40-year-old has not featured since retiring due to an injury in the first round to Aliaksandra Sasnovich at Wimbledon and is now ranked as the world number 246.

And it does not appear as though Williams will be making a return to the WTA Tour soon, with Mouratoglou explaining that, at least in the short term, he will be coaching former world number one Halep.

"Today, I am starting a new chapter in my coaching career: I am now the full-time coach of Simona Halep," Mouratoglou tweeted on Thursday.

"In the last eight months, I realised how much I missed coaching. It is the passion of my life, and I still feel like I have so much to give.

"Simona came to the Mouratoglou Academy before Indian Wells for a training block. I swung by at a few of her practices, watched her train.

"At the end of the week, she asked me if I was available to coach her. I have the highest respect for her but it was out of the question at the time.

"A few weeks later. I had a conversation with Serena, and the door opened for me, at least short term, to work with someone else.

"I will keep you updated on what's coming next soon."

World number 20 Halep endured an injury-hit 2020 and 2021, and split with long-time coach Darren Cahill in September of last year. The Romanian has won two grand slam titles, triumphing at Roland Garros in 2018 and Wimbledon the following season.

She has reached three other major finals and enjoyed a strong start to 2022, triumphing at the Melbourne Summer Set 1 prior to the Australian Open, in which she reached the round of 16.

Runs to the semi-finals at the Dubai Tennis Championship and Indian Wells Open have followed, though the 30-year-old will be hoping Mouratoglou can help her recapture the form she showed to end 2017 and 2018 on top of the WTA rankings.

Naomi Osaka is through to the third round of the Miami Open after beating former world number one Angelique Kerber in straight sets.

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.

Simona Halep has withdrawn from the Miami Open after aggravating a thigh injury.

Former world number one Halep was due to face Australia's Daria Saville in the round of 64 on Thursday but felt unable to contest the match.

Halep said she sustained a thigh injury during her Indian Wells semi-final defeat to Iga Swiatek the previous week and it caused her discomfort again while training on Wednesday.

The 30-year-old two-time major winner expects to sit out the Charleston Open and will miss the start of the Billie Jean King Cup.

In a tweet posted on her official Twitter account, Halep wrote: "While I was practising in Miami yesterday I felt a sharp pain in my left leg.

"I had been struggling with the thigh since my semi-final in Indian Wells and hoped it would improve, but I went for an MRI last night and unfortunately it showed a tear.

"My body needs time to heal and as a result I will be out of competition for three weeks. This means I have had to make the super tough decision to pull out of Miami, Charleston and Fed Cup [Billie Jean King Cup].

"While it feels like really disappointing news to share, I am keeping the confidence from my great start to the year and am motivated to do everything to be ready for the clay-court season.

"Thanks for your continued support through the highs and lows."

Lucky loser Harmony Tan will take Halep's place in the draw.

Iga Swiatek defeated Simona Halep 7-6 (8-6) 6-4 at the Indian Wells Open on Friday, progressing to the final and extending her winning streak to 10.

The Polish world number four came back from a break down in each set - as well as saving two set points in the first-set tiebreak - to level her head-to-head record with Halep at 2-2.

After taking out the WTA 1000 tournament in Doha last month, Swiatek has not had it all her way this week in California. Aside from a 6-1 6-0 trouncing of Madison Keys, the 20-year-old had to fight from a set down in her opening three matches.

Following a tight first set, Halep won three games in a row to take a 4-2 lead, but it was here Swiatek started to open up on return of serve.

She was ultimately able to capitalise on Halep's second serve, winning 14 of a total 21 points when given a second look, to earn five service breaks for the match.

Swiatek is now at least guaranteed to reach a career-high world number three ranking with, and a win in the final would move her to number two, only behind Ashleigh Barty.

She will meet Maria Sakkari in the final on Sunday, who broke down in tears after her hectic 6-2 4-6 6-1 win over Paula Badosa in the late match.

Despite Badosa having a higher first-serve rate than her opponent in the first set at 53.9 per cent, Sakkari was all over the second serve, winning nine out of a total 12 points.

After powering through the first set with flat hitting, the Greek world number six lost momentum in the second and forced play with rushed shot selection after getting broken early.

She still managed one of the shots of the match in trying to save that break of serve, scrambling across court to hit an underarm pass down the line.

Badosa kept her composure on serve to take the second set, winning 21 out of 29 points at an improved 72.9 per cent. Sakkari regrouped and exhibited her unique court coverage, however, taking the win after getting an early break.

Sakkari immediately broke down in tears afterwards, upon making her first WTA 1000 final and defeating the defending champion at Indian Wells.

Two top-ten talents have booked a date in the Indian Wells Open semi-final after Maria Sakkari and Paula Badosa won their quarter-finals in straight sets. 

First up, world number six Sakkari took on Ukrainian Elena Rybakina, prevailing 7-5 6-4.

Rybakina won the first three games of the match, working her way to an early 4-1 lead, before her Greek opponent rattled off six of the next seven games to claim the first set.

Sakkari again faced adversity early in the second set, coming back from 40-0 down in the second game to hold serve, before breaking the very next game to pinch the match-winning lead.

Former world number one Simona Halep emphatically dispatched unseeded Petra Matric 6-1 6-1 in Wednesday's quarter-final at the Indian Wells Open.

Halep landed 75 per cent of her first-serves and won those points at a rate of 82 per cent (27/33).

Martic's serve commanded much less respect, as she landed 69 per cent of her first-serves, but only won 36 per cent of those points (8/22).

After holding in her first service game, Martic allowed Halep to rattle off six consecutive games, with three double-faults assisting her Romanian opponent.

With the win, Halep booked a semi-final matchup against Poland's number three seed Iga Swiatek after she prevailed in her meeting with American Madison Keys in similar fashion.

Two-time major winner Simona Halep secured a spot in the Indian Wells Open last 16 with a strong 6-3 6-4 victory over 16th seed Cori Gauff on Sunday.

Halep, who is aiming to rebuild her ranking in 2022 after an injury-hit second half of last year, was excellent with her return, particularly on Gauff's second serve to gain the edge.

The Romanian saved all four break points generated by Gauff, while she converted three of the nine break points that she created.

Halep, who started the year with victory at the Melbourne Summer Set 1 before a last-16 loss to Alize Cornet at the Australian Open, needed only one hour and 16 minutes to seal her progress.

She will next play Romanian compatriot Sorana Cirstea after the 26th seed won 5-7 6-1 6-0 against lucky loser Anna Kalinskaya.

Last year's US Open champion and British 11th seed Emma Raducanu was bundled out by Croatian world number 79 Petra Martic 6-7 (3-7) 6-4 7-5.

Raducanu had served for the match in the final set but the Croatian won the final three games. Martic triumphed in two hours and 46 minutes, reaching the last 16 at Indian Wells for the second time in her career.

Martic will face 28th seed Liudmila Samsonova who triumphed 6-4 7-6 (7-4) over Danka Kovinic.

Third seed Iga Swiatek came from a set down to win 6-7 (3-7) 6-2 6-1 over Clara Tauson in two hours and 18 minutes.

Swiatek has won seven straight matches and is unbeaten at WTA 1000 events this season, having triumphed in Doha last month.

The Pole will take on three-time major winner Angelique Kerber in the last 16 after the German won comfortably over Daria Kasatkina 6-2 6-1.

American 25th seed Madison Keys got past countrywoman Alison Riske 7-6 (7-4) 6-1, setting up a fourth-round meeting with British qualifier Harriet Dart who beat Kaia Kanepi in straight sets.

Alison Riske produced a breathtaking comeback to beat Garbine Muguruza at the Indian Wells Open, turning around an apparent lost cause after losing the first nine games of the match.

Muguruza, who won the WTA Finals title at the end of last season, was cruising at 6-0 3-0, but 31-year-old American Riske, despite tossing her racket in frustration, refused to give up. Incredibly, she won 12 of the next 13 games to reach the third round at the expense of the world number nine.

"After the first set, it literally could not get any worse," Riske said in her on-court interview following a 0-6 6-3 6-1 success.

"So if I could try to get two balls in the court we might get somewhere. I was just trying to hang in there. I've played Garbine many times before and it's always been a battle."

This was Riske's fifth match against Spanish star Muguruza, and despite losing the first two of those, she had since beaten the two-time grand slam winner twice, albeit most recently at the 2019 US Open.

"I felt if I could get in there a little bit, I was going to have my chances," Riske said. "I know I've beaten her before, and if I could just bring out some of my game, good things were going to happen."

It was world number 53 Riske's 10th career victory against a player ranked in the top 10.

British player Harriet Dart pulled off a shock win over Ukrainian Elina Svitolina, as the world number 122 snatched a 2-6 6-3 6-3 victory over the 12th seed.

Three of the biggest names in the draw took the long route through to the last-32 stage, with Emma Raducanu, Simona Halep and Iga Swiatek taken to a deciding set in their opening matches, having benefited from first-round byes 

Raducanu fended off Caroline Garcia 6-1 3-6 6-1, while Halep was a 6-2 4-6 6-2 winner against Ekaterina Alexandrova, the Russian who is playing under a neutral flag.

Polish third seed Swiatek put a slow start behind her to beat Ukrainian Anhelina Kalinina 5-7 6-0 6-1 and is looking to build on her recent Qatar Open triumph. She said: "I'm pretty happy I could turn my head on to fight mode and stay focused, because that was the key I guess."

Last year's Wimbledon runner-up Karolina Pliskova bowed out, the Czech seventh seed losing 2-6 7-5 6-4 to Danka Kovinic of Montenegro.

Elina Svitolina and Simona Halep both fell in the first round of the Qatar Ladies Open, while Garbine Muguruza and Anett Kontaveit eased through on Monday.

Former world number one Halep, champion in Qatar back in 2014, was off the pace as Caroline Garcia claimed just her second win in nine meetings against the Romanian with a 6-4 6-3 triumph.

Number 10 seed Svitolina also suffered an early exit after ending up on the wrong side of an almost three-hour slog, with Tereza Martincova eventually succeeding 6-7 (2-7) 7-5 7-6 (7-5).

But fifth favourite Muguruza – a two-time finalist, including in 2021 – did not have much as trouble as she outfought Sorana Cirstea 7-6 (7-4) 6-1 in a second-round contest, with Kontaveit coasting through to round three in similar fashion with a 6-2 6-3 win over Ana Konjuh. 

Jelena Ostapenko, who is a former finalist in Doha and champion in Dubai last week, managed a sixth consecutive victory in the Middle East as she downed Oceane Dodin 6-4 6-2 to reach the second round, while 11th seed Elena Rybakina fell at the first hurdle to Jacques Cristian in a 6-4 6-3 loss.

Angelique Kerber, the 13th ranked player at the tournament, was another surprise first-round loser as she fell 4-6 6-3 6-2 to Jil Teichmann.

Cori Gauff secured her spot in the second round with a straightforward 6-2 6-3 victory over American compatriot Shelby Rogers, while 16th seed Elise Mertens battled to a 6-3 2-6 7-5 win over Jasmine Paolini.

Meanwhile, defending champion Petra Kvitova had no trouble easing past Irina-Camelia Begu 6-3 6-1, and Daria Kasatkina edged out Ajla Tomljanovic 6-4 6-7 (4-7) 6-2.

Jelena Ostapenko will meet Veronika Kudermetova in the Dubai Tennis Championships final after defeating Simona Halep 2-6 7-6 (7-0) 6-0 on Friday.

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.

Two-time champion Simona Halep strode through to the Dubai Tennis Championships semi-finals with a 6-4 6-3 win over eighth seed Ons Jabeur on Thursday.

A series of upsets meant Jabeur was the only seed left in the tournament going into Thursday, but she was outfought by Halep, whose win-loss record in 2022 now stands at 11-1.

The result followed two years on from Halep beating Jabeur in the second round at the same tournament, on that occasion needing a third-set tie-break to get the better of the Tunisia. Halep went on to win the title on that occasion.

"It was a very tough match. Even if it's in two sets, it felt much harder than that," Halep said of Thursday's win.

"I had in my mind big time the match from 2020, it was so close and I knew I'd have to fight till the end."

Quoted on the WTA website, former Wimbledon and French Open winner Halep added: "I've been focused on what I have to do, and I wanted just to push Jabeur back because she has such a big game."

Halep will face Jelena Ostapenko in the last four after the big-hitting Latvian overcame Petra Kvitova 5-7 7-5 7-6 (11-9).

Kvitova led by a set and a break, and twice served for the match, yet Ostapenko prevailed to add the 2013 Dubai champion to the scalps of Sofia Kenin and Iga Swiatek this week.

Ostapenko, who triumphed in two hours and 39 minutes, has now reached at least the semi-finals in four of her last seven tournaments.

The other semi-final will be contested by Veronika Kudermetova and Marketa Vondrousova.

Kudermetova reached her third career WTA 500 semi-final after beating lucky loser Jil Teichmann 6-2 5-7 6-4 in two hours and 23 minutes.

Vondrousova, meanwhile, became just the third ever qualifier to reach the last four of the tournament thanks to a 7-5 6-4 win over Dayana Yastremska.

Defending champion Garbine Muguruza, 2021 finalist Barbora Krejcikova and top seed Aryna Sabalenka were all eliminated from the Dubai Tennis Championships on Wednesday.

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.

Iga Swiatek, Simona Halep and Barbora Krejcikova had little difficulty progressing to the second round of the Dubai Duty Free Tennis Championships on Monday. 

The unseeded Halep, who was champion in 2020, needed just an hour and 11 minutes to see off Alison Riske 6-2 6-4 as she looks to climb back up the rankings. 

The two-time grand slam winner went into this week ranked 23rd in the world after a difficult 2021 that was ravaged by injury, but she was in fine form against Riske. She showed good spirit to dig herself out of a hole in the second set and save two break points – the American's only ones in the entire match – in the fourth game. 

Swiatek, seeded sixth, was even more comfortable against Daria Kasatkina, defeating the Russian 6-1 6-2 in just 65 minutes. 

Kasatkina had no answer to Swiatek in the first set and, by the time she started to gain some form of momentum, she was already a set and a break down. 

Swiatek had few issues closing out the match and was joined in the second round by Petra Kvitova, who dropped just two games en route to an emphatic 6-2 6-0 defeat of Camila Giorgi. 

Krejcikova was the highest seed in action. The Czech, who lost to Garbine Muguruza in last year's final, was given a tougher examination than some of her rivals, with wildcard Caroline Garcia putting up a solid fight. 

Krejcikova came through 6-4 7-6 (7-0) in the end, blowing the Frenchwoman away in the second-set tie-break, though she will surely have to sharpen up if she is to go one better than 2021 – the 26-year-old hit just 12 winners to 28 unforced errors. 

There was also a victory for Jessica Pegula in an all-American affair with Coco Gauff that included 10 breaks of serve – the former won 6-4 6-4. 

An emotional Alize Cornet said "it is never too late to try again" after reaching her maiden grand slam quarter-final with victory over Simona Halep at the Australian Open.

Cornet, who celebrated her 32nd birthday on Saturday, battled to a 6-4 3-6 6-4 victory in stifling conditions on Rod Laver Arena to set up a last-eight showdown with Danielle Collins, who beat Elise Mertens in three sets.

The Frenchwoman has now defeated two in-form former number ones in Halep and Garbine Muguruza, having also recovered from a set and 1-4 down to overcome Tamara Zidansek.

She is through to her first quarter-final in what is her 63rd grand slam appearance and is the first Frenchwoman to reach this stage at Melbourne Park since Marion Bartoli in 2009.

Cornet is playing in her 60th straight major, and should she compete in the main draws at Roland Garros, Wimbledon and Flushing Meadows, will set a new record for consecutive appearances in grand slams.

"It feels amazing," Cornet said in her on-court interview with Jelena Dokic. "It was a battle with Simona today. In this heat after 30 minutes we were both dying on the court.

"We kept going for two and a half hours with all our heart. Congrats to Simona because I know she struggled a lot and I admire this player so much. 

"She's such a fighter and an example to me. To beat her today to go to my first quarter-final is a dream come true. I don't know what to say. It's just magic. It's never too late to try again.

"This is why I keep playing tennis, for this moment where I can share all these emotions on the court with you."

Cornet had reached the last 16 at majors on five occasions prior to her victory over Halep in a run dating back 13 years when narrowly missing out on the Australian Open quarter-finals.

She was pegged back from a set and break up against Halep, losing 16 straight points at one point, and was clearly struggling with the heat as the match dragged into a decider.

But Cornet, who recently suggested this might be her final season playing professional tennis, showed incredible resolve to break Halep in the seventh game and hold her own serve to break her quarter-final hoodoo.

Halep congratulated Cornet, posting to her official Instagram account: "You have been stronger today! All the respect for you, Alize. Enjoy. I'll keep working to get better for another three-hour match when we meet again."

In her post-match media duties, Halep said: "I have only nice words about her, because I like her on court, how she's fighting.

"She deserves what is happening to her now. She works hard all the time, and I wish her good luck. I really want her to make this dream coming true."

There was to be another emotional moment for Cornet at the end of her victory speech as she praised 2009 Australian Open quarter-finalist Dokic for her work off the court since retiring eight years ago.

"I want to thank my box, but also I want to tell you something... how you moved on in your life, I think we can all congratulate you. You were an amazing player and now an amazing commentator," Cornet said as the pair embraced on court.

Dokic, who last week called out social media trolls for body-shaming her, responded: "You just made me cry. I can’t believe I'm crying. Thank you. Alize Cornet."
