New world number one Iga Swiatek says taking the top rank is a "dream come true" and something she never strongly believed could happen.

Swiatek made history as the first Polish tennis player to reach the top ranking, taking over the mantle following Ashleigh Barty's shock decision to retire from the sport in midweek. She will officially become number one when the WTA rankings are updated on April 4.

The 20-year-old Pole, who won the 2020 French Open and made this year's Australian Open semi-finals, made the ascent to the summit after beating Viktorija Golubic 6-2 6-0 at the Miami Open on Friday.

"It's a dream come true, for sure," Swiatek told reporters. "It's that kind of thing that I wanted to happen someday, but I didn't really know that it's going to be possible for me.

"I never really imagined that moment, because truth to be told, I was working day by day and I was playing tennis well, but I never had that like that strong belief that it can actually happen, so it's even more surreal for me."

Swiatek has claimed WTA 1000 titles at Indian Wells and Doha this year, with her victory over Golubic extending her winning run to 12 matches.

She is the 28th woman to reach the summit in the WTA rankings, becoming the youngest player at the top since Caroline Wozniacki in 2010.

"I think it's going to be a bit different and maybe the hype is going to be a bit bigger, but I'm ready for that," she said.

"Honestly, it's like part of the job, so I always knew if I'm going to succeed, it's going to be there. I really appreciate people being really enthusiastic and really pumped up because I think sometimes I'm even playing for them."

Barty was quick to congratulate Swiatek on claiming the number one ranking, saying there is "no better person" than the Pole.

"There is no better person," Barty said in a message. "The way that she's brought this fresh, fearless energy onto the court has been incredible.

"I hope she can take it and still be her, do it her own way, and really chase what she's after in her career and her dreams."

Former French Open champion Iga Swiatek has risen to world number one in the wake of Ashleigh Barty's retirement with a 6-2 6-0 win over Viktorija Golubic at the WTA Miami Open on Friday, sealing her ascent.

Swiatek, who won recent WTA 1000 events this year at Indian Wells and Doha, cruised to victory in one hour and 14 minutes over the Swiss.

The 20-year-old Pole, who won the French Open in 2020 and reached this year's Australian Open semi-finals, will officially become the top-ranked player when the rankings are updated on Monday April 4.

Barty's name will be removed from the rankings at her request having announced her shock retirement earlier this week at the age of 25, despite winning this year's Australian Open and last year's Wimbledon titles.

Swiatek is the 28th woman to reach the summit in the WTA rankings, becoming the youngest player at the top since Caroline Wozniacki in 2010. She will become Poland's first-ever number one in tennis history.

The Pole extended her winning streak to 12 matches against Golubic, taking her to a tour-high 21 wins this year, in a match where she saved eight of nine break points and took six of the nine she generated.

Swiatek's main immediate competition for the top rank was fifth seed Paula Badosa who got past Marie Bouzkova 7-5 7-5 in two hours and three minutes.

Badosa, who got the edge by grinding out games under pressure, will face Yulia Putintseva in the third round after she won 6-3 4-6 7-5 over Lesia Tsurenko.

Fourth seed Maria Sakkari was bundled out of contention following a shock 4-6 6-1 6-2 loss to Brazilian Beatriz Haddad Maia.

Two-time major winner Petra Kvitova needed three sets to get past Clara Burel, winning 6-1 3-6 6-3 in one hour and 45 minutes.

Jessica Pegula beat Sloane Stephens 6-1 6-4, Cori Gauff got past Qiang Wang 7-5 6-4 and 20th seed Elise Mertens went down 7-5 2-6 6-1 to Linda Fruhvirtova.

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.

Naomi Osaka looked relaxed and composed as she eased to a straight-sets win at the Miami Open, and offered a clue as to why when speaking to reporters afterwards.

The 24-year-old revealed she has started seeing a therapist after her recent loss at Indian Wells, where she suggested a heckler had affected her performance.

Osaka was left in tears as she struggled to deal with someone apparently shouting "Naomi, you suck!" during her second-round defeat to Veronika Kudermetova.

She also withdrew from Roland Garros last year, citing mental health concerns.

However, the three-time grand slam champion produced a strong display in her first round encounter in South Florida to beat Astra Sharma 6-3 6-4 on Wednesday.

"I don't know if I'm allowed to say this, but I finally started talking to a therapist after Indian Wells. It only took like a year after French Open," she told reporters after her win.

"She kind of told me strategies and stuff. I realise how helpful it is. I'm glad that I have people around me that told me to, like, go in that direction.

"But, yeah, I was basically just remembering all the things that she told me to do, just to take deep breaths and reset myself when I need to."

The world number 77 revealed it was partly her sister, former professional player Mari Osaka, showing concern that led her to seek out therapy.

"I feel like I've been trying a lot of different things because I tend to internalize things, and I also want to do everything by myself," Osaka clarified, adding that her coach, Wim Fissette, had also encouraged her to do so.

Osaka believes she is now better prepared to handle a similar situation to Indian Wells should it arise, having realised it may have been the first time she has been heckled during a game.

"I think for me, the situation in Indian Wells, I've kind of thought back on it. I realise I've never been heckled. I've been booed, but not like a direct yell-out kind of thing. It kind of took me out of my element.

"I feel like I'm prepared for it now. I was kind of bracing myself before the match to just know that's a thing that could happen now. I think I just needed to change my mindset a little."

Naomi Osaka moved to extinguish the painful memories from Indian Wells as she eased into the second round of the Miami Open.

The three-time grand slam champion, who was left in tears as she struggled to deal with a heckler during her second-round defeat to Veronika Kudermetova at Indian Wells, produced a composed display in South Florida to see off Astra Sharma 6-3 6-4.

Needing an hour and 20 minutes to defeat her Australian opponent, Osaka secured her 50th WTA 1000 win, one that sets up a battle of two former world number ones.

Osaka will next face Angelique Kerber, having kept her cool against Sharma despite converting just two of 11 break point opportunities and squandering three match points.

"I didn't want to let anything bother me, no matter what happened," Osaka said.

"The last match I played was not the greatest memory for me. I wanted to prove that I could come back out here and compete, and no matter if I won or lost, to just know that I had the best attitude I could."

Kerber promises to prove a much sterner test for Osaka, who has lost her last four matches against the German, having won their first encounter at the 2017 US Open.

Osaka's Japanese compatriot Misaki Doi crashed out in a straight-sets defeat to Vera Zvonareva, while promising teenager Clara Tauson retired in the third set of her match with Zhang Shuai.

Madison Brengle was among those to progress on Wednesday, continuing the theme of early American success.

Shelby Rogers continued her recent good form as she won an all-American clash with Amanda Anisimova in the first round of the Miami Open.

Rogers beat 10th seed Jelena Ostapenko en route to the third round at Indian Wells, where she lost in three sets to last year's US Open finalist Leylah Fernandez.

Both Rogers and Anisimova have experience of going into the second week of a grand slam, yet it was the more experienced Rogers who had the edge in South Florida, prevailing 3-6 6-0 6-3 in a stirring comeback.

Speaking on-court after the win, Rogers highlighted the challenge Anisimova poses when she is in form.

"[Anisimova] can come out and dictate play like nobody else when she is on fire, it's hard to do anything," she said.

"I felt like I had to counter that a little bit better. I was a little passive in the first, just running side to side.

"She played incredible. I'm just really happy I closed it out because I knew she was going to raise her level again at the end."

Round two will see a reunion between Rogers and Ostapenko, while Simona Halep, a two-time semi-finalist in Miami, will face Australia's Daria Saville.

Saville, formerly Daria Gavrilova, was ranked as high as 20 back in 2017, but had surgery on her Achilles last February.

A run to the last 16 at Indian Wells, including a top-10 win over Ons Jabeur, delivered a reminder of her quality and she will have the chance to claim another big-name scalp after beating Greet Minnen 7-5 6-3.

Elsewhere in the first round, there were wins for Marta Kostyuk, Magda Linette and Ekaterina Alexandrova.

Kaia Kanepi booked a second-round meeting with Sara Sorribes Tormo, while Heather Watson ended her six-year losing streak in Miami and will next face 15th seed Elina Svitolina.

World number one Ashleigh Barty maintained her winning run in Miami with her best performance of the 2021 tournament to date dispatching of Elina Svitolina to book a spot in the final.

Barty defeated fifth seed Svitolina 6-3 6-3 in Thursday's semi-final, hitting 27 winners and breaking her Ukrainian opponent five times.

The Australian had been down a match point in her opening clash of this year's Miami Open against Kristina Kucova but the 2019 champion has responded to every challenge since.

However, Barty needed three sets to overcome both Victoria Azarenka and Aryna Sabalenka in earlier rounds before making more light work of Svitolina to make it 11 straight wins in Miami, given 2020's event was cancelled.

Barty will play 2019 US Open winner Bianca Andreescu in Saturday's final after she defeated Naomi Osaka's conqueror Maria Sakkari 7-6 (9-7) 3-6 7-6 (7-4) in Thursday's other semi-final.

"Yeah, I think it was," Barty said in her on-court interview when asked if it was her best match of the tournament.

"I think [with] Elina, you have to produce your best tennis. Happy with the way we were able to execute today."

Svitolina went into the match with a 5-1 head-to-head advantage over Barty, while the Australian had not played on foreign soil prior to the event since February 2020, opting to step away from the tour during the COVID-19 pandemic.

"With the head-to-head we had, I almost see myself as the underdog, I really do," Barty said.

"It gives me the chance to go out there and play with freedom. To play not careless but carefree tennis."

Barty has reinforced her world number one ranking from Osaka, who lost to Sakkari in the quarters, by progressing this far although adding a second Miami Open title will be top priority.

The 24-year-old 2019 French Open champion had a medical timeout between sets to tend to a preexisting abdominal issue but said she would be fine for the decider on Saturday.

"Yeah, I was a little bit sore," she said. "I got some assistance with some tape on it. But knowing we’ve got a day to recover tomorrow, I promise you I’ll be right as rain and then we’ll be good to go."

Eighth seed Andreescu booked her place in the decider with a strong three-set victory over 23rd seed Sakkari in a match which finished in the early hours of Friday morning.

The Canadian won in two hours and 42 minutes in a match full of momentum shifts, as Andreescu won her fourth three-setter in five matches in Miami this week.

World number one Ashleigh Barty maintained her winning run in Miami with her best performance of the 2021 tournament to date dispatching of Elina Svitolina to book a spot in the final.

Barty defeated fifth seed Svitolina 6-3 6-3 in Thursday's semi-final, hitting 27 winners and breaking her Ukrainian opponent five times.

Barty will play 2019 U.S. Open winner Bianca Andreescu in Saturday's final after she defeated Naomi Osaka's conqueror Maria Sakkari 7-6 (9-7) 3-6 7-6 (7-4) in Thursday's other semi-final.

"Yeah, I think it was," Barty said in her on-court interview when asked if it was her best match of the tournament.

Eighth seed Andreescu booked her place in the decider with a strong three-set victory over 23rd seed Sakkari in a match which finished in the early hours of Friday morning.

The Canadian won in two hours and 42 minutes in a match full of momentum shifts, as Andreescu won her fourth three-setter in five matches in Miami this week.

Maria Sakkari insisted there was still room for improvement despite ending Naomi Osaka's 23-match winning streak in stunning fashion at the Miami Open.

Osaka had not lost for over a year prior to Wednesday's outing, putting together the ninth-longest unbeaten run seen on the WTA Tour since the start of 2000.

However, this year's Australian Open champion was simply unable to match her opponent's high standards in their quarter-final clash, resulting in a 6-0 6-4 triumph for the excellent Sakkari.

World number 25 Sakkari had battled hard to get past Jessica Pegula in the previous round – including saving six match points – but needed just 69 minutes to see off four-time grand slam champion Osaka, who managed just five winners during her surprisingly brief stint out on court.

Afterwards, Sakkari revealed how coach Tom Hill helped devise a strategy to trouble the second seed – albeit she had to come from 3-0 down after a difficult start to the second set.

"I don't think tennis-wise it was like the best tennis I have ever played in my life," said Sakkari, according to the WTA Tour's website.

"I think I executed our strategy with Tom really well. I just did what I had to do. I'm not gonna tell you what. What we discussed before the match, I just did it most of the match, except maybe a couple of games where things didn't go right."

Osaka's previous loss was back in February 2020, when she was also beaten in straight sets by Sara Sorribes Tormo at the Billie Jean King Cup.

Since then, she has won last year's US Open and then the first grand slam in 2021, though the loss to Sakkari did not come as a complete surprise to her having struggled for rhythm in Miami.

"She's a really big fighter so I knew it wasn't going to be easy. I felt like I haven't been playing well this whole tournament," Osaka said.

"I couldn't find a groove, so mentally it's really hard for me to play against really high-quality players with what I feel is low-quality tennis."

Next up for Sakkari in the semi-finals is another former grand slam champion – Bianca Andreescu.

Triumphant at Flushing Meadows in 2019, eighth seed Andreescu outlasted Sorribes Tormo 6-4 3-6 6-3 in the day's final match at the WTA Premier event.

Ash Barty's grip on the world number one ranking remains for now after winning in three sets against seventh seed Aryna Sabalenka in the Miami Open quarter-finals on Tuesday.

The 2019 Miami Open champion defeated Sabalenka 6-4 6-7 (5-7) 6-3 in humid conditions in South Florida to reach the last four, where the Australian will face fifth seed Elina Svitolina.

Svitolina won in the later match on Tuesday over Latvia's Anastasija Sevastova 6-3 6-2.

Barty, the 2019 French Open champion, did not drop her serve once against the Belarusian, saving seven break points throughout the match as she bids to retain her top ranking.

Barty is under threat from 2021 Australian Open winner Naomi Osaka for the number one ranking, with the Japanese also into the quarters.

The Australian will retain the top ranking by reaching the decider, regardless of second seed Osaka's results.

"It was a brilliant match today," Barty said in her on-court interview. "It was certainly the best level I’ve played for a long time and especially over a sustained period.

"Aryna really made me bring out my best stuff today. She’s an exceptional competitor."

Barty has now won 10 consecutive matches in Miami, dating back to her 2019 title with 2020's event cancelled due to the COVID-19 pandemic.

Ukraine's Svitolina, ranked fifth in the world, reached the Miami Open semi-finals for the first time with her win over the unseeded Sevastova.

"I've always wanted to play well here in Miami," said Svitolina, who made last year's French Open quarter-finals.

"It's one of the biggest tournaments and playing here is always amazing, so I'm really pleased with the performance tonight."

World number two Naomi Osaka and defending champion Ash Barty advanced to the quarter-finals of the Miami Open.

Osaka reached the last eight at the WTA Premier event for the first time in her career thanks to Monday's straight-sets win over Elise Mertens.

World number one Barty overcame two-time grand slam champion Victoria Azarenka in a tough three-set battle in Miami.

THERE'S NO STOPPING OSAKA

Australian Open champion Osaka extended her winning streak to a remarkable 23 matches.

Osaka defeated 16th seed Mertens 6-3 6-3 to stay hot – Venus Williams, Serena Williams, Justine Henin and Azarenka are the only other players with winning streaks of 23 or more matches since 2000.

"It definitely feels very special," four-time major winner Osaka said. "This is one of my favourite tournaments to play, and of course I'm sad I hadn't been able to get to the second week the last times that I have played this tournament. But I'm here now, and hopefully it will go well this time."

Maria Sakkari is next for Osaka after the 23rd seed saved six match points in her 6-4 2-6 7-6 (8-6) win over Jessica Pegula.

BARTY WINS BATTLE OF PAST AND PRESENT NUMBER ONES

In a rollercoaster battle, top seed Barty prevailed 6-1 1-6 6-2 against 14th seed Azarenka.

Barty extended her winning streak in Miami to nine matches after coming out on top against the former world number one.

"Playing against Vika you have to be ready right from the first point," Barty said. "I felt like I did that well in the first set and she gave me a few cheap errors. Then through the second she lifted her intensity.

"I probably wasn't sharp enough in those first couple of games to be able to go with her, particularly with new balls. When Vika is ahead and she's a front runner, she's the very best in the world."

Aryna Sabalenka stands in the way of Barty and the semi-finals after the seventh seed trounced Marketa Vondrousova 6-1 6-2.

SVITOLINA WINS THRILLER, ANDREESCU RALLIES

Fifth seed Elina Svitolina rallied past two-time Wimbledon winner Petra Kvitova 2-6 7-5 7-5.

Svitolina made a slow start against the red-hot ninth seed, but the 2018 WTA Finals champion finished strongly to progress.

Anastasija Sevastova took down Ana Konjuh 6-1 7-5 to set up a clash with Svitolina.

Meanwhile, eighth seed and 2019 US Open champion Bianca Andreescu came from behind to defeat two-time slam winner Garbine Muguruza 3-6 6-3 6-2.

Naomi Osaka did not raise a sweat en route to the Miami Open last 16 as Garbine Muguruza moved through but Sofia Kenin and Karolina Pliskova bowed out.

Australian Open champion and second seed Osaka benefited from a walkover after qualifier Nina Stojanovic withdrew ahead of Sunday's clash due to a right thigh injury.

Elise Mertens will face Osaka following the 16th seed's 6-2 0-6 6-2 win against Anett Kontaveit.

Two-time grand slam winner Muguruza rallied past Russian wildcard Anna Kalinskaya at the WTA Premier event.

However, fourth seed Kenin was sent packing as sixth seed Pliskova was tamed by nemesis Jessica Pegula in Miami.

MUGURUZA STAYS HOT

Spanish star Muguruza dug deep to earn her tour-leading 20th win of the season.

Former world number one Muguruza – the 12th seed – prevailed 4-6 6-3 6-4 against Kalinskaya, having trailed 3-0 in the final set.

"I brought my fighting spirit and I could match the level of fighting against Anna, and very happy to go through these tough matches," Muguruza said following two hours, 41 minutes on court.

"Doesn't matter if you play pretty or you play ugly, but you stay strong and you go through these rounds. That gives me an opportunity to feel better and to have another chance."

Muguruza – who has the most final appearances this season with three, having won the Dubai Tennis Championships and finished runner-up at the Qatar Open and Yarra Valley Classic – will next face eighth seed Bianca Andreescu.

Former US Open champion Andreescu overcame fellow seed Amanda Anisimova 7-6 (7-4) 6-7 (2-7) 6-4.

KENIN'S WOES CONTINUE

It has been a rough 2021 for American star Kenin.

Stunned in the second round of the Australian Open – in her title defence – Kenin then crashed out of the Phillip Island Trophy at the first hurdle.

Kenin rallied to beat Andrea Petkovic first-up in Miami, but the 22-year-old was beaten 6-4 4-6 6-4 by 27th seed Ons Jabeur.

Jabeur and Sara Sorribes Tormo – who shocked 21st seed Elena Rybakina 6-1 3-6 6-2 – will meet for a spot in the quarter-finals.

PLISKOVA FALLS TO PEGULA… AGAIN

For the third time this past month, 2019 Miami Open runner-up Pliskova went down 6-1 4-6 6-4 to 29th seed Pegula.

Australian Open quarter-finalist Pegula conquered Pliskova in Doha and Dubai before repeating the feat in Miami on Sunday.

"I played her a lot the last three weeks, three tournaments," Pegula said. "I kind of expected her to play well there. Even when I was up I still felt like she could easily come back just because she plays so aggressive and she serves well."

After reeling off the final four games, Pegula set up a last-16 showdown with 23rd seed Maria Sakkari, who dismantled qualifier Liudmila Samsonova 6-0 6-1.

World number one Ash Barty moved through to the last 16 of the Miami Open, where Simona Halep's campaign came to a premature end.

Defending champion and top seed Barty was too good for Jelena Ostapenko in Saturday's showdown between the former French Open winners.

Two-time grand slam winner Victoria Azarenka also moved through to the fourth round of the WTA Premier tournament.

Halep, however, succumbed to a shoulder injury in Miami.

CLASH OF PAST AND PRESENT NUMBER ONES

Barty and former world number one Azarenka will go head-to-head for a place in the quarter-finals.

Australian star Barty accounted for Ostapenko 6-3 6-2 as she extended her winning streak at the Miami Open to eight matches.

Barty, who tallied nine winners to 14 unforced errors, rallied from 2-0 down in the second set by reeling off six successive games to advance.

"Today felt like I was a lot sharper and switched on and ready to go from the very first point," Barty said afterwards.

Three-time Miami champion Azarenka trumped Angelique Kerber 7-5 6-2 in the third round.

Azarenka – the 14th seed – fought back from a 4-1 deficit in the opening set to get the better of the three-time major winner.

"She's a very talented player. I always have been a huge fan of her game and the way she plays, the way she handles herself. She has a lot of variety," Azarenka said on facing Barty. "She has pretty much every single shot there is. [It's] going to be a great match."

INJURED HALEP PULLS OUT

Two-time grand slam champion Halep withdrew due to a shoulder injury as Anastasija Sevastova benefited from a walkover.

"I'm very sorry to I have to pull out of the singles and doubles at the Miami Open, but my injury doesn't let me play here as expected," said Halep.

"I'm sad that I can't continue, I wanted to come here to give my best and play many matches but unfortunately I can't. 

"Hopefully next year I will come back healthy and better."

Next up for Sevastova is wildcard Ana Konjuh, who stunned 15th seed and reigning French Open champion Iga Swiatek 6-4 2-6 6-2.

SVITOLINA AND SABALENKA ROLL ON

Ukrainian fifth seed Elina Svitolina booked her spot in the round of 16 after overcoming fellow seed Ekaterina Alexandrova 7-6 (7-1) 6-4.

Two-time Wimbledon winner Petra Kvitova stands in the way of a quarter-final berth – the ninth seed was too good for 17th seed Johanna Konta 6-1 6-2.

Seventh seed Aryna Sabalenka, meanwhile, prevailed 7-6 (7-4) 6-4 against Veronika Kudermetova.

Belinda Bencic – the 11th seed – was sent packing 4-6 6-4 6-4 by Marketa Vondrousova, who will take on Sabalenka.

Simona Halep has withdrawn from the Miami Open due to a shoulder injury.

Halep beat Caroline Garcia in the second round in Florida on Thursday, but an issue with the world number three's right shoulder prevented her from facing Anastasija Sevastova.

The two-time grand slam champion said: "I'm very sorry to I have to pull out of the singles and doubles at the Miami Open, but my injury doesn't let me play here as expected.

"I'm sad that I can't continue, I wanted to come here to give my best and play many matches but unfortunately I can't. 

"Hopefully next year I will come back healthy and better."

Sevastova will face either French Open champion Iga Swiatek or Ana Konjuh in the round of 16.
