Daniil Medvedev landed a third title in three weeks by swatting aside fellow Russian Andrey Rublev in the Dubai Tennis Championships final.

Former world number one Medvedev won 6-2 6-2 in an hour and eight minutes, adding to recent victories in Rotterdam and Doha as he extended his winning streak to 14 matches.

It gave him a tour-leading 19th match win of the season, edging ahead of Britain's Cameron Norrie, and means Medvedev will vault above Rublev to reach sixth in the new ATP rankings.

Appearing in his 30th tour-level final, Medvedev picked up his 18th career title and improved his head-to-head advantage to 5-2 against his compatriot.

He broke serve in the first and seventh games to sweep through the opening set, serving out to love to clinch it, and Rublev, who was the defending champion, offered no greater resistance in the second.

After beating Novak Djokovic in the semi-finals, this was supremely clinical from Medvedev, setting him up for tilts at the Masters 1000 events in Indian Wells and Miami over the coming weeks.

"It's amazing," said Medvedev in an on-court interview, "because the start of the year was not perfect."

He lost in round three of the Australian Open to Sebastian Korda, but has put that January jolt firmly behind him.

"In tennis, when you don't win tournaments, you are always doubting, no matter what happens in practice," Medvedev said. "So I was doubting a lot and now it just feels better. I was really happy with these three weeks and I'm looking forward to the next ones.

"Sometimes you feel you're doing all the right shots and you're losing matches, and sometimes you kind of don't even think, just go it, go for some crazy stuff. A lot of shots this tournament were landing which were maybe not supposed to be, and when confidence is going sometimes that helps a lot."

Medvedev's win makes him the third player in the last two years to land three titles in as many weeks, the ATP said, after Casper Ruud in July 2021 and Felix Auger-Aliassime.in October 2022.

Daniil Medvedev denied Novak Djokovic a 21st consecutive win to set up an all-Russian final against Andrey Rublev at the Dubai Tennis Championships.

Djokovic had started 2023 by coming out on top in all 15 of his matches and winning the Australian Open, with his overall winning streak standing at 20 games.

But Medvedev ended the world number one's perfect start to the year with a superb display to take a 6-4 6-4 triumph on Friday.

The 27-year-old, who himself made it 13 consecutive wins, broke Djokovic twice on the way to taking the opening set.

Medvedev's high standard of play continued in the second, breaking Djokovic in the first game before holding in all five of his service games to secure a straight-sets victory.

"When you play against Novak you just have to play your best," Medvedev said after the win. "Kind of hope he doesn't play his best on the day because when he plays his best, well he has 22 grand slams, so even if you play your best, it is going to be tough, not sure you win.

"I managed to play a higher level than him today. In the second set I didn't face one break point, but there were so many 30-30 games. But I managed to stay composed and I am happy to be in the final tomorrow."

His win means he will face countryman Rublev in the final after the reigning champion kept his hopes of retaining the title alive with a 6-3 7-6 (11-9) success over Alexander Zverev.

Rublev had never previously won a match or set against Zverev in five previous meetings, but won three of the German's service games in the opener to go a set ahead.

The second seed was out-aced nine to two in the second set but managed to force a tie-break, going on to survive a set point before eventually securing the win on his sixth match point.

Rublev will look to join Roger Federer and Djokovic as only the third repeat champion at the tournament when he takes on Medvedev in Saturday's final.

The compatriots have met six times previously with Medvedev winning four of them, though Rublev has taken victory in their last two match-ups.

Novak Djokovic clinched a 20th win in a row and maintained his perfect year to date with victory against Hubert Hurkacz at the Dubai Tennis Championships.

The world number one cruised in the opening set, before Hurkacz put up more of a fight in the second.

Djokovic eventually prevailed to seal a 6-3 7-5 win, successfully seeing off his opponent despite Hurkacz valiantly throwing everything at him.

The 35-year-old Serbian has now won 15 consecutive matches in 2023, with his latest impressive display including just seven unforced errors, less than half Hurkacz's 15 as Djokovic's clinical edge proved decisive.

Fifteen successive victories is the fourth-best start to a season in Djokovic's career, though he remains some way off the 41-0 record he began 2011 with.

A semi-final clash against Daniil Medvedev awaits following the Russian's comfortable 6-3 6-2 victory against Borna Coric, which clocked in at one hour and 21 minutes.

Medvedev is also in the midst of an impressive winning streak, rattling off 12 consecutive successes since being eliminated by Sebastian Korda at the Australian Open in January.

Andrey Rublev booked his spot in the final four with a 6-3 7-6 (7-3) victory over Botic van de Zandschulp to maintain his title defence.

He will face seventh seed Alexander Zverev in the semi-final, the German having seen off Lorenzo Sonego 7-5 6-4.

Novak Djokovic swept through to the quarter-finals of the Dubai Tennis Championships with ease on Wednesday, clinching a 6-2 6-3 win over Tallon Griekspoor.

The Serbian picked up his 19th consecutive victory midway through his record 378th week as world number one, settling his last-16 clash in straight sets.

Griekspoor, at a career-high position of 39th in the ATP rankings himself, proved no match for the 22-time grand slam winner, who dismantled him inside an hour and 22 minutes.

Djokovic had looked poised for a near-flawless performance, with a late lost service game at 5-1 up in the second set the only major blemish on his display.

"It's been a great evening for me," Djokovic said in his post-match interview. 

"Yesterday [against Tomas Machac], I really had to work hard to get a win. Tonight, right from the blocks, I think I was sharp. I definitely played better than I did last night.

"Maybe the last three or four games weren't the best to close the match, but I managed to find a good serve in the end.

"I'm very pleased with the performance and with the way I felt on the court, and hopefully things can go in the right direction for tomorrow."

Djokovic, who remains undefeated in 2023, is bidding to win the Dubai title for a sixth time, in what represents his first tournament since he won the Australian Open in January. 

Elsewhere, second and third seeds Andrey Rublev and Daniil Medvedev joined Djokovic in easing their way into the last eight.

The former was made to work by Spain's Alejandro Davidovich Fokina however, recovering for a 1-6 7-6 (8-6) 7-6 (7-3) win, while the latter saw off Alexander Bublik 6-4 6-2.

Fourth seed Felix Auger-Aliassime crashed out with a surprise 7-6 (7-4) 6-4 loss to Italy's Lorenzo Sonego, who is rewarded with a last-eight clash against seventh seed Alexander Zverev.

Novak Djokovic was made to work hard for his 18th consecutive victory, eventually putting away Tomas Machac in the first round of the Dubai Tennis Championships.

Djokovic, who is celebrating a record 378th week as world number one, had to rely on a third-set tie-break to finally get over the line, defeating his Czech opponent 6-3 3-6 7-6 (7-1) on Tuesday.

Machac is ranked 130th in the world, but caused Djokovic plenty of problems, earning 10 break points across the match, though he was only able to convert three.

Djokovic had a 4-1 lead in the deciding set before Machac fought back to force a tie-break, but the Australian Open champion ultimately had few problems at 6-6 as he won seven of the eight points played to clinch the win.

"Tomas certainly didn't play like the No. 130 in the world today," Djokovic said of his opponent. "He was giving me all kinds of trouble. But I guess when it mattered, I found another gear."

Djokovic, who is still undefeated in 2023, will face Tallon Griekspoor in the second round.

Elsewhere, fresh off two titles in as many weeks, third seed Daniil Medvedev eased past Matteo Arnaldi 6-4 6-2 to tee up a tie with Alexander Bublik next after his opponent Alexandar Lazarov retired hurt with Bublik leading 6-1 1-0.

Felix Auger-Aliassime defeated Maxime Cressy 7-6 (7-4) 3-6 6-3, but sixth seed Karen Khachanov is out after he was beaten 7-5 6-2 by Botic van de Zandschulp.

The Dutchman will take on Mikael Ymer in the second round after his 6-2 6-3 win against Francesco Passaro, while eighth seed Borna Coric and Dan Evans played just four games before the latter retired hurt.

Christopher O'Connell set up a match against Alexander Zverev in the next round after he overcame Emil Ruusuvuori 7-5 6-4.

Novak Djokovic remains set on more success after surpassing Steffi Graf's record for weeks spent at world number one.

On Monday, Djokovic celebrated a 378th week as the best player in men's tennis, which overtook the all-time record (for men or women) set by Graf.

Like Graf, Djokovic has won 22 grand slam titles, though the 35-year-old remains in the hunt for more glory.

After his Australian Open triumph earlier this season, Djokovic will be hoping a 94th ATP Tour-level title comes his way at this week's Dubai Tennis Championships.

"I still want more achievements," Djokovic said ahead of breaking Graf's record.

"I could not have imagined this, I was dreaming as a kid to be Wimbledon champion, to be number one in the world. I achieved those dreams in 2011.

"After that, I wanted more. Of course, I'm driven by the goals. I'm as dedicated to the sport really as anybody else.

"It's surreal in a way to be that many weeks at world number one, to match Steffi Graf, who is one of the all-time greats of our sport. Just being among these legendary names is flattering. I'm very proud."

Djokovic's campaign in Dubai starts against Tomas Machac on Tuesday.

Andy Murray has pulled out of the Dubai Tennis Championships, with the tournament citing the player's recurring hip injury as the reason.

Murray reached the final of the Qatar Open, which he lost 6-4 6-4 to Daniil Medvedev on Saturday, and had to play three sets in every match during his run to the showpiece.

The world number 52 impressed in Doha, including beating Alexander Zverev and saving five match points against Jiri Lehecka in his semi-final.

However, the toll on the 35-year-old seems to have led to his decision not to participate in Dubai, with the tournament beginning on Monday.

A statement from the tournament read: "We regret to inform you that Andy Murray is unable to participate in this year's tournament.

"Andy has been dealing with a recurring hip injury that has unfortunately forced him out of Dubai. We wish Andy a speedy recovery and hope to see him back on the court in Dubai soon."

Murray's win over Lehecka in Qatar meant he moved level with Jimmy Connors in fifth on the list for most ATP hard-court wins in the Open Era (489).

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.

Novak Djokovic says his participation at the Indian Wells Open and Miami Open is "out of his control".

Djokovic, who last month won the Australian Open to move level with Rafael Nadal on 22 grand slam titles, has not played since claiming the title in Melbourne.

The world number one was nursing a hamstring issue throughout the season's first major, but he confirmed at a press conference in Belgrade on Wednesday that he will return to action at the Dubai Tennis Championships next week.

Djokovic could not compete in the United States last season due to his COVID-19 vaccination status, though his brother Djordje has claimed the 35-year-old has applied for a "special permit" to enter the country.

He has received clearance from the tournament organisers to play at the two Masters 1000 events at Indian Wells and in Miami but now faces a wait to find out if the U.S. government will grant him entry.

"The process for that has started. It is out of my control now," Djokovic said.

"I'd love to play and I'm glad I received the approval of directors in Miami and Indian Wells. I hope the decision makers will give the approval."

On his progress on the injury front, Djokovic explained: "As for the injury I sustained at the Australian Open, it's healed, but I'm not 100 per cent yet.

"Things are looking very good. As a team, we made the decision to go to Dubai."

Djokovic has won the Dubai Tennis Championships five times, though the last of those titles came in 2020.

He was knocked out by Jiri Vesely in the quarter-finals last year.

Djokovic this week tied Steffi Graf on 377 weeks spent as world number one.

The outright record is set to become his next week, with Carlos Alcaraz unable to surpass him even if the young Spaniard wins the Rio Open.

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.

Sorana Cirstea beat world number 12 Beatriz Haddad Maia in the longest WTA Tour match of the year so far at the Dubai Tennis Championships.

Liudmila Samsonova ousted Paula Badosa on Sunday in a three-set victory that lasted three hours and 22 minutes.

That record was exceeded by eight minutes a day later – Cirstea prevailing 4-6 7-6 (9-7) 7-5 in her first-round encounter with 11th seed Haddad Maia.

Cirstea, ranked 70th in the world, fended off two match points in the second-set tie-break and took that momentum into the decider.

Haddad Maia has lost four of her five meetings with Cirstea, though had defeated the Romanian in Adelaide in January.

"I fought really hard today. I really think I gave it all," Cirstea said.

"I have nothing left. Sometimes you just have to stay in there. Bia played amazing. You know, tennis is not fair sometimes. You play for three hours and a half, and it's a difference of a point.

"I wasn't planning to break the record! But Bia's been in great form, and I knew coming in she's a great fighter.

"I think this is what tennis is about, where all the work pays off. Sometimes it doesn't matter if it's a first round or a final, the joy is the same."

Another marathon encounter was played out between Veronika Kudermetova and Anhelina Kalinina, with the latter winning 6-3 5-7 7-5 in three hours and three minutes.

Karolina Muchova will face Cirstea in the next round after she saw off Bernarda Pera 6-1 6-4, with her victory including an early contender for shot of the tournament.

Muchova was scampering back towards the baseline as she looked set to lose a thrilling rally, only for the Czech to execute a perfect tweener lob.

Australian Open champion Aryna Sabalenka received a bye to round two, where she will face Lauren Davis after the American's victory over Jil Teichmann.

Jelena Ostapenko dispatched Katarina Zavatska 6-1 6-4 with the minimum of fuss, while Victoria Azarenka overcame Anastasia Pavlyuchenkova in straight sets.

Azarenka has won 135 WTA-1000 main-draw matches in straights sets, at least three more than any other player.

Karolina Pliskova defeated Marketa Vondrousova to set up a meeting with Yulia Putintseva, with Ana Bodgan, Aliaksandra Sasnovich and Shelby Rogers also victorious.
