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.

World number one Iga Swiatek proved too good for 32nd seed Bianca Andreescu as she emerged victorious 6-3 7-6 (7-1) in Monday's third round at the Indian Wells Open.

Swiatek started shakily as her serve was broken in the first game of the match, and although she got it back instantly, both competitors ended up creating eight break point opportunities each in a closer-than-expected match.

She will meet England's Emma Raducanu in the fourth round after the resurgent 20-year-old collected her best win of the year, defeating 13th seed Beatriz Haddad Maia 6-1 2-6 6-4.

Raducanu, the 2021 US Open champion, has begun to work her way back up the rankings. Having come into the tournament ranked 77th in the world after an injury-riddled season, she has now won four of her past five matches, with her only loss in that span coming against world number six Coco Gauff at the Australian Open.

World number five Caroline Garcia was pushed to a third set for the second match in a row, but prevailed 6-4 6-7 (7-5) 6-1 against Leylah Fernandez, booking a clash against Romania's Sorana Cirstea after she won 6-3 6-1 against fellow unseeded competitor Bernarda Pera.

Karolina Muchova kick-started a great day for the Czech Republic representatives as she got the better of Italy's Martina Trevisan 6-4 3-6 6-4, and Marketa Vondrousova kept it going with a 7-6 (7-5) 6-4 victory over world number four Ons Jabeur.

Reigning Wimbledon champion Elena Rybakina is shaping up as a threat to win it all, yet to drop a set this week following her 6-3 7-5 triumph over Paula Badosa.

Top seed Iga Swiatek spurned the chance for a double-bagel victory over Claire Liu at the Indian Wells Open on Saturday but she still cruised into the third round in 66 minutes.

The 21-year-old Pole, who won last year's Indian Wells, had match point at 6-0 5-0, before Liu rallied back on serve to avoid the ignominy of a double-bagel defeat, with Swiatek eventually winning 6-0 6-1.

Swiatek was in a dominant mood, winning 57 of 83 points for the match and converting five of nine break points generated. She dropped only 11 points in seven service games.

The three-time grand slam champion is 13-3 on the season, with all 13 wins coming in straight sets. In five of those matches, she has dropped just one game.

Former US Open winner Emma Raducanu moved into the third round with a 7-6 (7-3) 6-2 win over 20th seed and 2023 Australian Open semi-finalist Magda Linette.

Raducanu's win meant she has put together back-to-back victories for the first time since September, setting up a clash with 13th-seed Beatriz Haddad Maia after she beat Katerina Siniakova 5-7 7-6 (7-4) 6-3.

Fourth seed Ons Jabeur fought back from a set down to prevail over Magdalena Frech 4-6 6-4 6-1 in one hour and 44 minutes.

Former US Open champion Bianca Andreescu also overcame an early deficit to win 4-6 6-4 6-3 over Peyton Stearns.

Reigning Wimbledon champion Elena Rybakina got the edge in a tight two-set clash with 2020 Australian Open winner Sofia Kenin, triumphing 7-6 (8-6) 7-6 (7-5) in two hours and 10 minutes. Rybakina fought back from 4-1 down in the second frame.

Fifth seed Caroline Garcia overcame a wobble to win 6-1 6-7 (4-7) 6-4 over Hungary's Dalma Galfi, with 30th seed Leylah Fernandez her next opponent after beating Emma Navarro 6-2 6-4.

Two-time major winner and three-time US Open finalist Victoria Azarenka was the big casualty from the day's play, losing 7-6 (7-1) 6-3 to 2021 Australian Open semi-finalist Karolina Muchova.

Novak Djokovic's absence from the Indian Wells Open has caused a stir in US politics, and on the tennis court it is hugely significant, too.

Sport was given a jolt three years ago when Indian Wells organisers cancelled the event on the eve of action getting under way, citing one local case of COVID-19.

At that point, on March 8, 2020, there had been more than 500 confirmed cases across the United States, with 21 deaths. Soon enough, events across the globe were being postponed or scrubbed.

Coronavirus travel restrictions prevented the unvaccinated Djokovic from taking part last year, and they will keep him away again this time, despite calls from two Florida senators for the jab requirement to be lifted by President Biden to allow the Serbian into the country.

With the world number one sidelined, Daniil Medvedev and Carlos Alcaraz look likely challengers for the men's title. There have been surprise champions in recent times, with Cameron Norrie winning in 2021 and Taylor Fritz carrying off the title 12 months ago, so it would be hasty to rule out something similar.

In the women's event, there has not been a successful title defence since Martina Navratilova won in 1990 and 1991. That can partly be attributed to Serena and Venus Williams boycotting for over a decade at the peak of their powers after complaining of facing racial abuse, and in their absence no player stepped up to dominate.

Iga Swiatek triumphed in Indian Wells and Miami last season, racking up the 'Sunshine Double', and she starts as a strong favourite again, but defeat in the recent Dubai final to Barbora Krejcikova showed the 21-year-old rankings leader will not have everything her way this season.

First-round action gets under way on Wednesday, after two days of qualifying, and here Stats Perform, with Opta data, looks at what lies ahead.

After Norrie and Fritz, could there be another shock men's winner?

Djokovic has won a joint-record five Indian Wells titles, but he last featured in 2019, when he lost to Philipp Kohlschreiber in round three.

Rafael Nadal is also absent this time with a hip injury, and with Roger Federer retired this will be the second Indian Wells main draw since 2000, after 2021, to feature none of the ATP Big Three.

The Big Three was a Big Four at one point, though, and Andy Murray will be competing. It is one of the two Masters 1000 tournaments Murray has never won, along with Monte Carlo, having triumphed at the other seven. Murray has the most match wins at Indian Wells among all men competing this time, having 28 to his name, two more than John Isner who sits next on the list.

No ATP player has a better win percentage at Indian Wells than Djokovic (84.7 per cent), who has won 50 of his 59 matches, while the now-retired Federer has appeared in the most finals (nine), also winning five times, so there is no doubt the field is missing its long-time classiest acts.

Fritz last year became the first men's champion aged under 25 years old since Djokovic in 2011, and he was also the first American to take the men's title since Andre Agassi beat Pete Sampras in the 2001 final.

Medvedev has won three consecutive tournaments in the lead-up this year, tearing to titles in Rotterdam, Doha and Dubai, but the Russian has a disappointing record at Indian Wells, having yet to reach the quarter-finals in five visits.

Just four players this century, including Alcaraz last year, have reached the semi-final stage before turning 20, with Nadal, Djokovic and Murray the other three. Alcaraz is still only 19 but a shade older than Boris Becker when he was a 19-year-old champion in 1987, the youngest men's winner.

Who else might come through? It feels like a free-for-all and Felix Auger-Aliassime will be hoping for a breakthrough tournament, with the Canadian being the only member of the current ATP top 10 to have never reached a final at ATP 1000 level. It has to happen sooner rather than later, surely.

Swiatek bids to lift curse of women's champions

Ever since Navratilova's two in a row, being a back-to-back champion at Indian Wells has been beyond all singles players on the WTA side.

Indeed, the only players to reach the final the year after their title run have been Lindsay Davenport (champion 1997, runner-up 1998) and Ana Ivanovic (champion 2008, runner-up 2009).

Nine women have won twice at Indian Wells, but none have managed three or more titles. The nine are: Steffi Graf, Mary Joe Fernandez, Navratilova, Daniela Hantuchova, Serena Williams, Kim Clijsters, Victoria Azarenka, Davenport and Maria Sharapova.

A Swiatek victory would make it a club of 10, but there is a club of one when it comes to players who have captured two titles without dropping a set in either trophy run. Sharapova is the only player to pull off that feat, with her 2006 and 2013 glory runs.

Among all women, Davenport has reached the most finals (six) and won the most matches (47), with Azarenka having the most wins among active WTA players (34).

Navratilova remains the oldest champion, having won aged 34 in 1991, while Martina Hingis and Serena Williams won as 17-year-olds in 1998 and 1999.

Shocks can happen: Bianca Andreescu took the title as a wildcard in 2019, while Jenny Byrne reached the final as a qualifier in 1989, the first year the women's event was staged.

If there is to be a teenage women's finalist this time, maybe it will be Coco Gauff. The American turns 19 midway through the tournament, on March 13, and has yet to reach a WTA 1000 final, although she got to the French Open title match last year, where Swiatek inflicted a heavy defeat.

Perhaps Aryna Sabalenka can reprise her Australian Open form, having won a first major in Melbourne. But Sabalenka's record in Indian Wells is a rough one, with the Belarusian yet to go past the fourth round.

Strap in for a thrill ride. They all want to stop Swiatek, but if any player can defy history it might just be the Pole.

Barbora Krejcikova stunned Iga Swiatek to win the Dubai Tennis Championships, cruising past the world number one in straight sets to clinch her first WTA 1000 title. 

By following up victories over Aryna Sabalenka and Jessica Pegula with a ruthless 6-4 6-2 dismantling of Swiatek, Krejcikova became just the fifth woman to beat each of the world's top three players at a single tournament in the last 40 years.

Krejcikova entered Saturday's meeting as the only player to have beaten Swiatek in her eight hard-court finals at tour level, having done so at the Ostrava Open last October.

The Czech looked to be drawing on that experience as she made a flying start, breaking in the opening game through a well-struck backhand. 

Though Swiatek responded with a break of her own in the sixth game, a rare double fault from the Pole saw the momentum swing Krejcikova's way.

Another excellent backhand return gave Krejcikova the opening set's decisive break, after which a visibly frustrated Swiatek was handed a time violation by the umpire.

Things did not get much better from there for the three-time grand slam winner, with a series of masterful returns helping Krejcikova seal two dominant breaks before wrapping things up.

Having clinched a highly impressive win within 91 minutes, Krejcikova told Amazon Prime Video: "It means a lot. 

"It was a great week for me, I was improving with every single game and today, I think I showed my best. 

"I really have to admire Iga for what she is doing. To me, she is a big inspiration and she motivates me every day. It was a great final and I'm definitely happy with the result."

Barbora Krejcikova will play Iga Swiatek for the Dubai Tennis Championships title after settling a see-saw semi-final against Jessica Pegula in ruthless fashion.

Having seen Swiatek brush aside Coco Gauff in straight sets in the first match of the day, Krejcikova would have been confident of doing likewise after taking the opener against Pegula.

Third seed Pegula battled back to take the second set, though, and the American appeared to have momentum on her side, only to bow out in a one-sided decider, losing 6-1 5-7 6-0 for her first defeat to Krejcikova.

The pair's only prior meeting had been a straight-sets win for Pegula at the Australian Open earlier this year.

Pegula's sole other tournament since Melbourne had ended in similar circumstances to this one, with a 6-3 6-0 crushing at the hands of Swiatek in the final of last week's Qatar Open. The Pole is who Krejcikova must play next.

Krejcikova is the first player since Svetlana Kuznetsova in Cincinnati in 2019 to beat two top-three opponents at the same WTA 1000 tournament.

Yet after seeing off number two Aryna Sabalenka in the quarter-finals and number three Pegula in the semis, she faces the world number one in the final.

Swiatek has had a rather more straightforward path, granted a walkover in the last eight and then, on Friday, playing Gauff, who she continues to dominate.

The Pole is now 6-0 across her career against Gauff, winning all of those matches in straight sets.

Gauff at least made Swiatek work a little harder than she has in many recent matches, going down 6-4 6-2 – the first match since Melbourne in which the number one has not won a set either 6-0 or 6-1, piling up the 'bagels' and 'breadsticks'.

Swiatek is 2-1 against Krejcikova for her career, although the Czech won their most recent meeting and their only encounter in a final in Ostrava last year.

Australian Open champion Aryna Sabalenka lost for the first time in 14 matches, and Coco Gauff set up a semi-final clash with Iga Swiatek at the Dubai Tennis Championships on Thursday.

Sabalenka fought back from a set down to end the title defence of Jelena Ostapenko a day earlier, but she came up short against Barbora Krejcikova as her Czech opponent overcame a tough first set to run out a 0-6 7-6 (7-2) 6-1 victor.

Sabalenka, playing in her first event since claiming a maiden grand slam title in Melbourne, romped into the lead by breaking Krejcikova's serve three times to go a set ahead.

But the world number two was pegged back in the second as Krejcikova battled to force a tie-break, which she dominated to level the match.

Krejcikova then completed the shock victory in style, breaking the second seed twice in the final set before clinching the win on her third match point to end Sabalenka's run of 13 straight triumphs.

Karolina Muchova's withdrawal due to an abdominal injury means it is Jessica Pegula who will face Krejcikova in the semi-finals on Friday.

After Swiatek reached the final four by virtue of Karolina Pliskova pulling out because of an illness, Gauff set up a sixth meeting with the world number one by beating Madison Keys 6-2 7-5.

In those five previous clashes between the pair, Gauff is yet to win a set.

But after cruising past Keys, doing so by converting four of five break points and winning 90 per cent of her service games, Gauff is confident of improving her dismal record against Swiatek on Friday.

"All five times, I did something wrong," Gauff said. "To be honest, she's playing great tennis and there's a reason she's world number one. 

"Tomorrow I have no pressure. I just have to play my game. I definitely think I've gotten better since the last time I played her.

"Ranking is just a number at the end of the day. You just have to step on the court believing you can win, and that's what I'm going to do tomorrow."

Australian Open champion Aryna Sabalenka fought back from a set down to end the title defence of Jelena Ostapenko at the Dubai Tennis Championships.

Sabalenka, playing in her first event since claiming a maiden grand slam title in Melbourne, recovered from falling behind in style to win 2-6 6-1 6-1 on Wednesday.

Ostapenko won the tournament last year and looked to be in with a chance of extending her winning streak in Dubai to seven matches.

But Sabalenka launched a strong recovery to reach the quarter-finals and extend a stunning run to start the season to 13 consecutive wins.

The second seed tightened up her game in the second and third sets and will face either Petra Kvitova or Barbora Krejcikova in the last eight.

Sabalenka had been broken three times by Ostapenko in the opening set, but she only had to fend off one break point from there.

"In the first set, she played unbelievable tennis and I couldn't do anything," Sabalenka said.

"I was looking at my team asking like, 'What can I do?', but somehow, I turned around this game and started playing really incredible tennis. 

"She plays really fast, deep balls, and I tried to stay super low, stay focused, and try to put more balls in than she did. I'm so happy that I did it."

A lower back injury for Wimbledon champion Elena Rybakina robbed supporters of what had looked like being a thrilling matchup against Coco Gauff.

The withdrawal of Rybakina meant Gauff progressed via a walkover and will face fellow American Madison Keys next.

Keys and Gauff have played twice before, winning one match apiece.

It was Gauff who won their most recent encounter in the third round of the US Open last year.

Top seed Iga Swiatek had earlier booked her place in the last eight, with the Pole's latest dominant showing in Dubai earning praise on social media from Andy Murray.

And news followed that Karolina Pliskova, her semi-final opponent, had been forced to withdraw.

Swiatek benefited from a walkover in the quarter-finals en route to winning the Qatar Open last week and is now only two wins away from another title.

Iga Swiatek stormed into the last eight at the Dubai Tennis Championships with an emphatic victory over Liudmila Samsonova.

It only took 76 minutes for the number one seed to record a 6-1 6-0 triumph on Wednesday, continuing a fine run after her triumph in Qatar last week.

Swiatek had only narrowly beaten Samsonova in an epic three-set encounter in the Stuttgart semi-finals last year, but was completely dominant this time around at the WTA 1000 event.

Samsonova struggled in recording a first-serve percentage of just 58.5, and Swiatek was ruthless in winning 19 of 22 points on the Russian's second serve.

Swiatek did not even have to fend off a break point in cruising to victory and will play Karolina Pliskova in the quarters.

Pliskova, the two-time grand slam finalist, battled to a 7-5 6-7 (6-8) 6-2 win over Anhelina Kalinina to reach the last eight in Dubai for the fifth time in her career.

There were also two American successes, with Madison Keys needing only 57 minutes to beat Victoria Azarenka, who appeared to be struggling with her movement.

Keys had lost all of her previous four meetings with Azarenka but triumphed 6-2 6-1 in routine fashion.

And Jessica Pegula joined her compatriot in progressing, winning her first career meeting with Ana Bogdan in straight sets.

Elsewhere, 2019 winner Belinda Bencic crashed out, with Karolina Muchova, who also knocked out Maria Sakkari this week, triumphing 6-1 6-4 to book a quarter-final date with Pegula.

Iga Swiatek continued her ruthless form as she progressed with ease to the WTA Dubai Tennis Championships third round on Tuesday.

The world number one cruised to a 6-1 6-1 triumph over 2021 US Open finalist Leylah Fernandez, just three days after winning the Qatar Ladies Open in Doha.

That marked Swiatek's 41st main-draw victory in WTA 1000 events in just her 53rd outing, only Serena Williams and Maria Sharapova (52 each) have won more than 40 such matches in fewer attempts.

The 21-year-old has won her last 35 hard-court matches against opponents ranked outside the world's top 30, though Swiatek said she had to adapt against Canada's Fernandez.

"It wasn't that easy for sure. It was much tougher than the score said," said Swiatek, who will look to make the fourth round for the first time in Dubai when she faces Liudmila Samsonova.

"In the second set ... I needed to go a level up. I didn't have much time to get used to the conditions, but I'm just happy I could play solid tennis."

Jessica Pegula, the third favourite at the tournament, defeated Viktoriya Tomova 6-2 5-7 6-1 to set up a third-round battle with Ana Bogdan, who overcame Shelby Rogers 7-6 (7-3) 6-3.

Fifth seed Coco Gauff coasted past Aliaksandra Sasnovich with a 6-0 6-4 victory, teeing up a meeting with Elena Rybakina, who slammed six aces in a 7-5 6-2 defeat of Marie Bouzkova.

World number two Aryna Sabalenka, who defeated Rybakina at this year's Australian Open final, made light work of lucky loser Lauren Davis in a straight-sets rout as she claimed her 12th straight win in 2023.

Dubai's defending champion Jelena Ostapenko will be the next challenge for Sabalenka after defeating 17-year-old Linda Fruhvirtova for her seventh straight win at the event.

Barbora Krejcikova saved four match points en route to a 6-4 4-6 7-5 win over seventh seed Daria Kasatkina and will meet Karolina Pliskova next after she downed sixth favourite Maria Sakkari in straight sets.

Belinda Bencic and Marta Kostyuk played out the match of the day as the former claimed a 6-7 (7-9) 7-6 (7-5) 6-4 triumph, with that clash taking three hours and 27 minutes – the second-longest on the WTA Tour this year.

Iga Swiatek avenged an early-season loss to Jessica Pegula as she stormed to the Qatar Open title on Saturday, completing a stunning trophy defence.

In three matches, Swiatek surrendered only five games, sealing the title with a 6-3 6-0 victory over American Pegula.

A heavy defeat to Pegula in Sydney at the beginning of the year saw Swiatek reduced to tears, and she then lost in the fourth round of the Australian Open in Melbourne, albeit to eventual finalist Elena Rybakina.

Now Swiatek is back, with brutal wins over Danielle Collins and Veronika Kudermetova – allowing both players just one game each – preceding her dismissal of Pegula in the final.

The 21-year-old has 12 career titles and is off the mark in 2023, extending her head-to-head dominance to 5-2 over world number four Pegula.

Swiatek said: "I don't care how many games are won or lost. I just feel like I really found my rhythm here, and after a tough beginning of the season I could stay focused from the beginning to the end of the matches, and I'm pretty happy with my performance.

"I hope playing well here is going to be a routine."

The world number one sent a message of support during her on-court speech to the people of war-torn Ukraine, for whom she has helped to raise funds over the last 12 months.

Swiatek, from Poland, said she felt "a real throwback to last year", when this event was taking place as the Russian invasion of Ukraine began.

"This was the first tournament where I had a chance to make a speech when the war started in Ukraine," she said. "I feel like we all have pretty short memories, but we should all support Ukrainians with everything they're coping with every day.

"It's pretty disappointing the situation is not changing, but hopefully they will stay strong."

Iga Swiatek and Jessica Pegula will clash in a WTA Tour final for the first time after taking wildly contrasting routes through to the Qatar Open title match.

While Pegula was taken to three sets by Maria Sakkari on Friday, world number one and defending champion Swiatek required only 56 minutes to score a 6-0 6-1 drubbing of Veronika Kudermetova.

In windy conditions in Doha, the top two seeds set up a Saturday showdown that will have plenty riding on it in terms of their rivalry.

When Swiatek lost to Pegula in early January at the United Cup in Sydney, winning only four games, the Pole was left in tears.

The rematch will either see Swiatek reassert her dominance over Pegula, or see the American show she has the 21-year-old's number for now.

Swiatek won all four matches she played against Pegula last season, with French Open and US Open quarter-finals victories among that set, but their last match has put a fresh spin on the head-to-head.

Crushing Kudermetova showed Swiatek at her ruthless best, and the world number one said: "I feel great. I was pretty worried how I was going to cope with the conditions today so I'm glad I played a smart way and I'm pretty happy I was so solid."

She is relishing the chance to test herself against Pegula again, saying: "It always takes a lot to win against Jessie. She's a great player, a really solid one, and we'll see, honestly. I'm not going to predict anything or over-analyse, I'll just play my best tennis."

Pegula overcame Greek fifth seed Sakkari 6-2 4-6 6-1 in the first semi-final.

While Swiatek will be chasing a 12th WTA-level singles title, the 28-year-old Pegula is after a third such trophy.

Speaking of the Sakkari match, Pegula said: "That was probably the hardest conditions I've ever had to play in, wind-wise. I played very smart."

Iga Swiatek will play Veronika Kudermetova in the Qatar Open semi-finals after the Russian defeated Coco Gauff in the last eight.

World number one Swiatek was already assured of her semi-final place heading into Thursday as Belinda Bencic's withdrawal had granted her a walkover.

She could watch on then as Kudermetova upset fourth seed Gauff 6-3 3-6 6-1 in Doha.

Swiatek has won each of her previous two matches against Kudermetova in straight sets, but the world number 11 will be on a high after her first top-10 win of the season.

It will be the 25-year-old's second semi of the season, although she withdrew from her Adelaide 2 match-up against Bencic.

While Gauff is out, there remains American representation as her doubles partner Jessica Pegula made light work of Beatriz Haddad Maia 6-3 6-2.

Pegula, the second seed, will face Greece's Maria Sakkari, who overcame third favourite Carolina Garcia 6-2 6-7 (5-7) 7-6 (7-5) in a battling encounter.

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.

Elena Rybakina believes she can become the best player in the world if she performs as she did in the first week of the Australian Open after beating Iga Swiatek.

Wimbledon champion Rybakina claimed the scalp of the top seed on Sunday, winning 6-4 6-4 on Rod Laver Arena to reach the quarter-finals.

Swiatek was in a class of her own last year, winning eight titles – including the French Open and the US Open – to firmly establish herself as the best player in the world.

The Pole was the favourite to win the Australian Open for the first time, but the 25-ranked Rybakina sent her packing to set up a showdown with Jelena Ostapenko.

Rybakina made history with her fourth-round win, becoming the first woman representing Kazakhstan to reach the quarter-finals of the Australian Open.

The 23-year-old knows she has plenty to work on, but feels she can rise to the top of the rankings if she continues to improve and consistently match the high standards she has set at Melbourne Park.

Asked if she can be the best in the world when she's at her best: "Every opponent is really tough, and for sure for me I think there are still many things to improve.

"If I perform like I did this week and consistently, I will say that I can be number one, I can beat anyone. For now, I need to find my consistency."

Rybakina felt she was rewarded for taking such a positive approach against Swiatek.

"For sure when you play against the number one player, I think you have really nothing to lose. I knew that I had to be aggressive from the first ball because she's a great mover, and she defends really well.

"So I was trying to just attack her from the first ball, and it really worked well."
