Daniil Medvedev and Stefanos Tsitsipas progressed to the third round of the Madrid Open but there was no such luck for Felix Auger-Aliassime on Saturday.

Second seed Medvedev cruised past Italian qualifier Andrea Vavassori 6-4 6-3, teeing up a meeting with Alexander Shevchenko, who overcame Jiri Lehecka in straight sets.

Tsitsipas was made to work by Dominic Thiem, but the fourth seed battling from a set down to win 3-6 6-1 7-6 (7-5).

World number 40 Dusan Lajovic provided the shock of the day by defeating seventh seed Auger-Aliassime 6-2 3-6 7-6 (7-5).

Denis Shapovalov, the 21st seed, was another surprise second-round loser, falling 6-7 (4-7) 6-4 7-6 (7-1) to China's Zhang Zhizhen.

Taylor Fritz avoided adding to the list of notable early eliminations in the Spanish capital, the eighth seed battling to a 7-6 (13-11) 6-4 victory over Christopher O'Connell.

Fritz's fellow American Frances Tiafoe progressed with a 6-3 7-6 (7-5) triumph over Argentina's Tomas Martin Etcheverry, while 14th seed Tommy Paul crashed out after a 6-3 7-6 (7-3) defeat to Roman Safiullin.

Seeds Alex de Minaur and Sebastian Baez also navigated their way through to the third round, defeating Marco Cecchinato and Marcos Giron respectively, as did Cameron Norrie at the expense of Yosuke Watanuki.

Three of the top seeds in the Miami Open field were eliminated on Monday as Felix Auger-Aliassime, Hubert Hurkacz and Frances Tiafoe were all sent packing.

Fifth seed Auger-Aliassime was taken out 6-2 7-5 in one of the biggest wins of Francisco Cerundolo's career, with the Argentine avenging recent losses to the Canadian at both the Australian Open and the Indian Wells Open.

Adrian Mannarino's 7-6 (7-5) 7-6 (7-0) victory over eighth seed Hurkacz was arguably an even bigger upset, as it snapped his streak of nine consecutive losses against top-10 opponents at Masters 1000 events.

The 34-year-old Frenchman absorbed 20 aces from Hurkacz and still came out on top, limiting his own unforced errors to 13 for the match.

A third upset of the day saw unseeded Italian Lorenzo Sonego play a near faultless match to eliminate 12th seed Tiafoe, finishing the contest with 22 winners and only two unforced errors, while not facing a single break point in the brief 68-minute battle.

There was no drama for Daniil Medvedev as the fourth seed received a walkover against Alex Molcan, and he will face France's Quentin Halys in the fourth round after his 7-6 (7-2) 6-3 triumph over Mackenzie McDonald.

Two seed Stefanos Tsitsipas almost joined the long list of seeded victims, but he prevailed 6-3 4-6 6-4 against Christian Garin in the day's only three-setter.

The Greek star will meet Russian 14th seed Karen Khachanov in the fourth round after his comfortable 6-2 6-4 result over Jiri Lehecka, while unseeded American Christopher Eubanks finished the day's play with a 6-3 7-6 (9-7) defeat of Gregoire Barrere.

Hubert Hurkacz prevailed 6-7 (10-12) 7-6 (9-7) 7-6 (8-6) in a thrilling three-and-a-half hour battle against Thanasi Kokkinakis during Saturday's second round of the Miami Open.

It was Hurkacz's first match of the tournament after the eighth seed received a bye through the first round, and he came up against a match-fit Kokkinakis after the Australian went three sets in his opening victory.

The world number nine had to save five Kokkinakis match points before sealing the win with his first chance, three hours and 34 minutes after the contest began.

Kokkinakis was not the only Australian on the day to go down in a gruelling three-setter as 15th seed Alex De Minaur fell 6-7 (5-7) 7-6 (7-3) 7-6 (10-8) to Quentin Halys in three hours and 20 minutes.

It was far smoother sailing for fourth seed Daniil Medvedev in his 6-1 6-2 triumph over Roberto Carballes Baena, giving the Russian his first win since his 19-match unbeaten streak was ended at the hands of Carlos Alcaraz in the Indian Wells Open final.

The biggest upset of the day came from France's Gregoire Barrere as he eliminated 11th seed Cameron Norrie 6-3 6-2, before Adrian Mannarino ensured a great day for the French contingent with a 6-4 3-6 6-1 result against Ben Shelton in the late window.

Fifth seed Felix Auger-Aliassime needed a pair of tiebreakers to dispatch Brazil's Thiago Monteiro 7-6 (7-5) 7-6 (10-8), while big-serving 19th seed Matteo Berrettini came out on the wrong side of some tiebreakers in his 7-6 (10-8) 7-6 (7-5) loss to Mackenzie McDonald.

The skid from 18th seed Lorenzo Musetti continued as the 21-year-old went down 6-4 6-4 to Jiri Lehecka, giving the Italian seven losses from his past eight matches.

Karen Khachanov fought off the challenge of recent Chile Open finalist Tomas Martin Etcheverry 6-1 3-6 6-3, and second seed Stefanos Tsisipas received a walkover as Richard Gasquet withdrew.

Rafael Nadal has dropped out of the world's top 10 men's tennis rankings for the first time in almost 18 years.

Nadal has been in the top 10 ever since April 2005, but on Monday fell to 13th in the ATP rankings after injury forced him to miss Indian Wells.

The 36-year-old's run came to an end on the same day that teenage compatriot Carlos Alcaraz reclaimed his number one spot from Novak Djokovic after beating Daniil Medvedev in Sunday's Indian Wells final.

Nadal is yet to recover from the hip injury that has hampered him since his Australian Open exit to Mackenzie McDonald in January.

Though the 22-time grand slam winner could return to the top 10 once he is back in action, it will not be in the next month as he has also withdrawn from the Miami Masters.

The latest ATP rankings saw Djokovic drop to second place, while Medvedev moved from sixth to fifth, Felix Auger-Aliassime leapt from 10th to sixth, Hubert Hurkacz nudged into the top 10 as he moved up two places to ninth, while Taylor Fritz dropped from fifth to 10th.

Top seed Carlos Alcaraz moved into the Indian Wells Open quarter-finals after Jack Draper retired down 6-2 2-0 due to an abdominal injury in their last-16 clash on Tuesday.

Alcaraz was in control, winning the first set in 36 minutes before racing to a 2-0 lead inside 10 minutes before the Briton withdrew. Draper had battled the injury in the latter stages of Monday's win over Andy Murray.

Despite that, the Spaniard looked in good touch, setting up a quarter-final meeting with eighth seed Felix Auger-Aliassime, who has a 3-0 head-to-head record against him.

"I felt the ball really well. I'm really happy with that part," Alcaraz said. "I would say I returned well, I hit great shots. I finished the match with confidence in my shots, to come into the next round with more confidence."

Auger-Aliassime saved six match points in a dramatic triumph over 17th seed Tommy Paul to reach the last eight, winning 3-6 6-3 7-6 (8-6) in two hours and 48 minutes.

The Canadian trailed 0-40 on serve at 5-6 in the deciding set before winning the next five points. He repeated that feat, down 3-6 in the tie-break, capitalising on his first match point. Auger-Aliassime hit 31 winners for the match, along with 51 unforced errors.

Fifth seed Daniil Medvedev fought back from a set down and a rolled ankle to progress past Alexander Zverev 6-7 (5-7) 7-6 (7-5) 7-5 in three hours and 10 minutes.

Medvedev rolled his ankle in the sixth game of the second set, going down in pain but played on, in his longest-ever three-set match. The victory is the Russian's 17th in a row. Zverev committed 50 unforced errors across the match.

The Russian will take on Alejandro Davidovich Fokina in the last eight, with the Spaniard winning 6-3 6-4 over Chilean qualifier Cristian Garin.

Jannik Sinner cruised past Stanislas Wawrinka 6-1 6-4 in one hour and 39 minutes to move into the last eight where he will face reigning champion Taylor Fritz. The American won 6-4 6-3 over Hungary's Martin Fucsovics in one hour and 41 minutes.

British 10th seed Cameron Norrie will play 14th seed Frances Tiafoe in the other quarter-final, with the former winning 6-2 6-4 over the higher-ranked Andrey Rublev. Tiafoe won 6-4 6-4 over Alejandro Tabilo in 83 minutes for his 150th career win.

World number two Carlos Alcaraz made it 10 wins from 11 matches in 2023 after defeating Tallon Griekspoor 7-6 (7-4) 6-3 in round three at the Indian Wells Open.

Alcaraz, 19, kicked off his 2023 campaign with eight wins in a row, including an Argentina Open title, before losing to Cameron Norrie in the Rio Open decider.

He has yet to drop a set at this fortnight's tournament in California, following up his opening win over Thanasi Kokkinakis with another strong showing against 31st seed Griekspoor.

The Spaniard will look to keep his strong form going when he meets Jack Draper in the fourth round, after 21-year-old Draper prevailed 7-6 (8-6) 6-2 in a battle of the Brits against Andy Murray.

Murray, who came into the match with six wins from his past seven outings, had an opportunity to take the match by the scruff of the neck but could not capitalise on a set point before going down in a tight tie-break, before Draper took charge.

California's own Taylor Fritz lived up to his fourth seeding, with the defending champion having little trouble in overcoming Argentina's Sebastian Baez 6-1 6-2, and he will play Hungary's Marton Fucsovics for a spot in the quarter-final.

Fucsovics, after upsetting 16th seed Alex De Minaur in the previous round, got the better of Slovakia's Alex Molcan 6-4 6-2.

Former world number three Stan Wawrinka showed he still has some gas in the tank after a surprise 6-2 6-7 (5-7) 7-5 triumph over world number eight Holger Rune, with the 37-year-old showing what he has learned through competing at the top level for as long as the 19-year-old Dane has been alive.

Jannik Sinner, the 13th seed, successfully navigated the challenge of veteran Adrian Mannarino for a 7-6 (9-7) 6-4 victory, Tommy Paul won his top-20 showdown against Hubert Hurkacz 4-6 6-2 6-4, and eighth seed Felix Auger-Aliassime knocked out Francisco Cerundolo 7-5 6-4.

Top seed Carlos Alcaraz and reigning champion Taylor Fritz both overcame challenges to progress into the third round of the Indian Wells Open on Saturday.

Alcaraz won 6-3 6-3 over Thanasi Kokkinakis in one hour and 18 minutes in his opening match of the event, which also marked his return from a fortnight out with a hamstring injury.

The Spaniard, who reached the semi-finals at Indian Wells last year, could return to the number one ranking with victory at this year's event in the absence of Novak Djokovic.

Alcaraz hit 21 winners against the 94th-ranked Australian, dropping only one point on serve in the opening frame.

Fritz went a set down against 2023 Australian Open quarter-finalist Ben Shelton but eventually prevailed 4-6 6-4 6-3 in one hour and 53 minutes.

Both players were excellent on serve throughout the contest, with Fritz earning a break in the 10th game of the second set to tie up the match, before swooping again in the sixth game of the decisive frame.

Veteran Andy Murray moved into the third round with a 6-4 6-3 win over Radu Albot, with the Briton to take on countryman Jack Draper next. Draper won 6-4 6-2 over 24th seed Daniel Evans.

Murray had been set to face 15th seed Pablo Carreno Busta in the second round, but he withdrew due to a muscle injury, allowing Albot into the draw as a lucky loser. Murray's win was his first in straight sets since October.

Seventh seed Holger Rune won 7-5 6-3 over American Mackenzie McDonald, progressing to face Stanislas Wawrinka after he toppled 26th seed Miomir Kecmanovic 7-6 (10-8) 6-4.

Ninth seed Hubert Hurkacz got past Australian Alexei Popyrin 6-3 6-3, setting up a third-round clash with 17th seed Tommy Paul who won 6-3 6-3 over Jan-Lennard Struff.

Eighth seed Felix Auger-Aliassime won 7-6 (7-5) 6-4 over Pedro Martinez, while 11th seed Jannik Sinner got past veteran Richard Gasquet 6-3 7-6 (7-2).

Last week's Mexican Open champion and 16th seed Alex de Minaur was the highest seed to be knocked out on Saturday after a 6-4 6-2 loss to Martin Fucsovics.

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.

Andy Murray will play Daniil Medvedev in the Qatar Open final after the 35-year-old came through yet another lengthy contest in his semi-final against Jiri Lehecka.

Murray appeared to be on course for a routine win after taking the first set 6-0, but was broken early in the second, eventually losing 6-3 to take him to a fourth three-set contest in four matches this week in Doha.

Lehecka should have won a hard-fought decider when 5-4 and 40-0 up on his own serve, but Murray's trademark resilience saw him break back despite facing five match points against, before ultimately winning the tie-break 8-6.

"I don't know how I managed to turn that match around," Murray said after the win. "In the 5-4 game, I think I played most of the match points really well. He missed one bad shot on the deuce point in that game at 5-4, but I played the match points pretty well.

"It's been an amazing start to the year. I have never experienced this in my whole career, like this many matches... It was sort of looking [like it might be a quicker match] for 30 minutes and then it turned into something completely different. Yeah, just amazing that I managed to turn that around."

Murray equalled Jimmy Connors for the fifth-most ATP hard court wins in the Open Era (489), and will play Medvedev in the final after the Russian's 6-4 7-6 (9-7) win against Felix Auger-Aliassime.

The Canadian had three set points in the second set tie-break to try and force a decider, but Medvedev showed determination to turn it around and seal his place against Murray in the final.

At the Open 13 Provence, number one seed Hubert Hurkacz is through to face Alexander Bublik in the semi-finals, with both also having to come through three-set matches in a deciding tie-break.

Hurkacz was finally able to overcome Mikael Ymer 6-3 3-6 7-6 (8-6) before Bublik defeated Grigor Dimitrov 7-5 3-6 7-6 (8-6).

Third seed Alex de Minaur was shocked by Benjamin Bonzi, who broke the world number 23 four times on his way to a 6-2 6-4 victory to avenge his third-round defeat at the Australian Open.

Bonzi will meet qualifier Arthur Fils in the final four after the French 18-year-old beat former world number three Stan Wawrinka 6-2 6-3 to reach a second straight tour-level semi-final.

Andy Murray and Daniil Medvedev sealed their place in the Qatar Open semi-finals while top seed Andrey Rublev was upset 4-6 6-4 6-3 by Jiri Lehecka.

Rublev won this tournament in 2020 and looked to be on his way to the final four after a strong opening set put him ahead.

But Lehecka battled back in the second to level the match and then found a crucial break in the second game of the deciding set to seize the advantage.

It was a lead he would not relinquish, holding his nerve despite watching a pair of match points come and go to clinch victory and knock out the world number five.

Lehecka will meet Murray in the semi-finals after the Brit came from a set down to see off Alexandre Muller 4-6 6-1 6-2 and keep his hopes of winning the Qatar Open for a third time alive after back-to-back titles in 2008 and 2009.

A tough opener had Murray facing a deficit against the world number 170, but a typically gutsy display saw him pull off the comeback and reach his first tour-level semi-final since June 2022, when he lost in the Stuttgart Open final to Matteo Berrettini.

Medvedev sealed his place in the final four with a hard-fought 6-2 4-6 7-5 win over Christopher O'Connell.

The world number eight triumphed for the seventh straight match, but did not have it all his own way against his Australian opponent, needing a crucial break with the final set tied at five games each to put himself back into the ascendancy.

Felix Auger-Aliassime awaits Medvedev in the next round after prevailing over Alejandro Davidovich Fokina in straight sets.

The world number nine out-aced his opponent eight to two to author a 6-4 7-6 (7-5) victory after one hour and 48 minutes, and he will look to improve on his dismal record against Medvedev on Friday, having lost all five of his meetings against the Russian.

At the Open 13 Provence, top seed Hubert Hurkacz reached the quarter-final after rallying from a set down to see off Leandro Riedi 4-6 6-3 6-2.

Second seed Jannik Sinner was forced to withdraw through illness, sending wildcard Frenchman Arthur Fils into the final eight, where he will meet Stan Wawrinka.

Alex De Minaur teed up a clash with Benjamin Bonzi by cruising past Alexander Ritschard 6-3 6-3, while world number 25 Grigor Dimitrov will play Alexander Bublik on Friday after beating Gijs Brouwer in straight sets.

Andrey Rublev and Andy Murray battled to outlast their opponents at the Qatar Open, while Daniil Medvedev breezed into the quarter-finals.

Top seed Rublev, who won this tournament in 2020, responded to a first-set setback to rally to a 1-6 6-1 7-6 (8-6) win over Tallon Griekspoor on Wednesday.

The world number five was staring at a fourth opening-round defeat in five appearances this year but saved three match points en route to fighting back from 5-2 down in the decider.

Murray and fourth seed Alexander Zverev played out another three-set thriller in the Middle East, with the former world number one triumphing 7-6 (7-5) 2-6 7-5.

That clash lasted three hours and three minutes in another marathon match for Murray after defeating Italian Lorenzo Sonego in a final-set tie-break in the first round.

Medvedev (3) had no such difficulty in a comfortable 6-4 6-3 victory over world number 147 Liam Broady.

Second seed Felix Auger-Aliassime had to regain his composure during his debut in Doha, but ultimately prevailed 4-6 6-1 6-4 against Jason Kubler.

World number eight Auger-Aliassime had lost his only previous meeting with Kubler, and an upset was on the cards after the Canadian was broken in the third game and was unable to recover.

Yet he found his form with a blistering second set, reeling off five straight games to restore parity and keeping his cool in the decider.

That victory teed up a last-eight meeting with seventh seed Alejandro Davidovich Fokina, who downed Kwon Soon-woo 6-3 6-2.

Jiri Lehecka will meet favourite Rublev after beating Emil Ruusuvuori 6-2 7-6 (7-2), while Botic Van De Zandschulp was shocked by world number 170 Alexandre Muller in a straight-sets defeat.

Elsewhere at the Open 13 Provence, fifth seed Maxime Cressy fell to a surprise second-round elimination after a 6-7 (5-7) 6-4 6-3 loss to home favourite Benjamin Bonzi.

There was no such luck for the other Frenchmen in Marseille as Alexander Bublik eased past Gregoire Barrere, while Stan Wawrinka beat Richard Gasquet 4-6 7-5 6-2 to reach the last eight.

Daniil Medvedev was at his brilliant best as he ended Felix Auger-Aliassime's title defence at the Rotterdam Open.

Former world number one Medvedev committed just five unforced errors in a 6-2 6-4 win on Friday that saw him progress to the semi-finals.

"Today was my best match of the week, but I have to build on this," Medvedev said afterwards.

"Usually, the best weeks you play, many times you're going to play your best tennis in the last match, so that's definitely a goal.

"But I'm happy with my level today, beating someone like Felix in straight sets."

He will next face Grigor Dimitrov, who needed three sets to see off Alex de Minaur.

Dimitrov saved two match points in claiming a 6-3 3-6 7-6 (8-6) victory but seemingly has an uphill challenge having lost four of his six matches against Medvedev.

"I kind of know the plan for the game,” Medvedev added of his clash with Dimitrov. "The thing is, he is going to try to do the same, to make up a good plan. If we take the last two matches, it's 1-1. So I always say a new match is a new match, no matter the head to head. 

"I'm preparing for a tough one tomorrow, he's such a great player and today was a great match from him, a great comeback actually. So I'm ready for the tough fight tomorrow."

Jannik Sinner was just as impressive as Medvedev, cruising to a 6-1 6-3 victory over three-time grand slam champion Stan Wawrinka.

Sinner, who won the Open Sud de France last week and has already dumped out top seed Stefanos Tsitsipas, will face Tallon Griekspoor after the Dutchman's win over fellow home hope Gijs Brouwer.

Defending champion Felix Auger-Aliassime must overcome a dismal record against Daniil Medvedev to go any further at the Rotterdam Open after both won on Thursday to set up a heavyweight quarter-final, while Stefanos Tsitsipas crashed out.

Third seed Auger-Aliassime beat French qualifier Gregoire Barrere 6-4 6-3, while Medvedev earned a 6-2 6-2 victory against Dutchman Botic van de Zandschulp.

Despite being the higher-ranked of the two at present, Canadian Auger-Aliassime has a 0-4 career record against Russian Medvedev.

Those losses include a painful defeat from two sets up in the 2022 Australian Open quarter-finals, and a US Open semi-final knockout blow in the previous season.

It is a record that is all the more surprising considering Auger-Aliassime has wins over Novak Djokovic, Rafael Nadal, Roger Federer, Andy Murray and Carlos Alcaraz to his name.

Auger-Aliassime sits eighth on the ATP ranking list, three places clear of former number one Medvedev, who is relishing their clash on Friday.

Medvedev said on Amazon Prime: "Felix is a top player. He won here last year and played amazing at the end of last season. I'm looking forward to a tough match, and hopefully I can be at my best.

"He's going to take his opportunities. He's going to go for it when he has the chance. So I will need to be at my best and everything has to be better."

Top seed and Australian Open runner-up Tsitsipas was beaten 6-4 6-3 by Jannik Sinner, with last week's Open Sud de France champion winning in an hour and 21 minutes to set up a quarter-final against Stan Wawrinka.

It was Sinner's first career win over a top-three opponent. The Italian held a 0-8 record against such opponents coming into this match.

Fourth seed Holger Rune is also out after retiring hurt while 6-4 4-0 down to Dutch wildcard Gijs Brouwer, who advances to play compatriot Tallon Griekspoor.

Australian Alex de Minaur advanced to the final eight with a 7-5 3-6 6-3 win over American Maxime Cressy, earning a shot at Grigor Dimitrov next.

Rotterdam Open top seed Stefanos Tsitsipas and defending champion Felix Auger-Aliassime were joined by Daniil Medvedev in progressing through their first-round ties.

Auger-Aliassime won his first Tour-level title at the event last year and went from strength to strength in 2022, winning another three singles trophies.

The world number eight, seeded third, started his title defence with a convincing 6-2 6-3 defeat of Italy's Lorenzo Sonego on Tuesday.

"Of course, I was hoping to win and get through, but 6-2, 6-3 is a great performance against a player that is tricky like he is... it's a great way to start the week," said Auger-Aliassime, who needed just 82 minutes to clinch victory and set up a last-16 meeting with qualifier Gregoire Barrere.

The Canadian is relishing his title defence, and feels he is a stronger competitor than this time last year in a warning shot to his rivals.

He added: "Last year was an amazing year, but this year is a different one. I think I'm a better player overall.

"Of course, the best thing I can do compared to last year is win again, so hopefully I can do that. The draw is really strong, but I'm confident if I can keep playing the way I did today I'll get my chances and then we'll see."

Auger-Aliassime might be the reigning champion, but world number three Tsitsipas is the favourite.

Emil Ruusuvuori was no match for Australian Open runner-up, who prevailed 7-5 6-1 and has a 13-1 record for the season.

"The process that you get to repeat these things over and over again, it gives you tremendous understanding of how things actually work," Tsitsipas said. 

"I think being able to get in these moments more and more often on the Tour helps you understand, makes you wiser when you're trying to deal with all these problems."

Tsitsipas, who could face Open Sud de France champion Jannik Sinner in the next round, ensured there would be no curse of the top seed in Rotterdam, where the favourite had lost their first match in two of the last three editions.

On both occasions (2020 and 2021), that was Medvedev, but the former world number one fought from a set down to beat Alejandro Davidovich Fokina 4-6 6-2 6-2.

World number 10 Hubert Hurkacz also had to battle against a Spaniard in the form of Roberto Bautista Agut. The fifth seed needed three hours to win 7-5 6-7 (7-9) 7-6 (7-4) and tee up an encounter with Grigor Dimitrov. 

Alexander Zverev defeated Soonwoo Kwon in straight sets to book his progress, while Gijs Brouwer got the better of Marc-Andrea Huesler.
