Defending champion Carlos Alcaraz cruised into the third round of the Barcelona Open with a 6-3 6-1 straight sets rout of Nuno Borges.

The world number two thrilled his home crowd with a ruthless performance against his Portuguese opponent to reach the last 16, converting five break points along the way.

Alcaraz will be joined in the next round by third seed Casper Ruud, after the Norweigian overcame American Ben Shelton in a 6-2 7-6 (7-1) victory.

Roberto Bautista Agut will not join them, however, after he suffered a 6-2 6-2 loss to Bernabe Zapata Miralles.

At the BMW Open, Dominic Thiem set up a second-round clash with Marc-Andrea Husler after receiving a walkover against Constant Lestienne.

The 2020 US Open winner had been leading 6-3 when the match was abandoned at 0-0 in the second set, as fifth seed Sebastian Baez slipped to a 6-3 7-5 loss against home favourite Oscar Otte in Munich.

Nuno Borges will face reigning champion Carlos Alcaraz in the second round of the Barcelona Open after a 6-2 6-3 triumph over Ilya Avashka on Monday.

Borges created a remarkable 20 break points, converting only five but still comfortable against his 61st-ranked opponent.

That sets up a clash with number one seed Alcaraz, who beat Pablo Carreno Busta in the 2022 final.

Ben Shelton's 7-5 6-4 success over countryman Mackenzie McDonald means he will take on Casper Ruud, while Bernabe Zapata Miralles will play Roberto Bautista Agut in an all-Spanish second-round affair after earning a routine 6-2 6-2 win over unfancied Attila Balazs.

Meanwhile, Emil Ruusuvuori beat Alexander Bublik in Barcelona for a second straight year to set up a second-round meeting with fifth seed Frances Tiafoe.

At the BMW Open in Munich, 2022 winner Holger Rune will open his defence against Yannick Hanfmann after the German battled from a set down to beat Thiago Monteiro 6-7 (3-7) 7-6 (7-5) 6-2.

Marcos Giron reached the second round with a 6-1 5-7 6-2 victory over Roberto Carballes Baene.

Carlos Alcaraz is the latest to confirm he will not be competing at the Monte Carlo Masters.

The world number two already has two titles to his name in 2023 but lost the final of the Miami Open to Jannik Sinner.

Alcaraz was set to compete in Monte Carlo when the clay court season begins next week but has joined compatriot Rafael Nadal in withdrawing due to injury.

Posting on Twitter, he said: "After two months abroad, I am happy to return home but sad because I finished my last match in Miami with physical discomfort.

"After visiting my doctor in Murcia today and being evaluated, I will not be able to go to Monte Carlo to start the clay court tour.

"I have post-traumatic arthritis in my left hand and muscular discomfort in the spine that needs rest to prepare for everything that is to come."

Alcaraz's defeat to Sinner in Miami saw him cede top-spot in the ATP world rankings to Novak Djokovic, having returned to the summit in March.

The Spaniard was previously ranked number one from September 2022 until January 30, 2023.

Jannik Sinner is through to the Miami Open decider after eliminating world number one Carlos Alcaraz 6-7 (4-7) 6-4 6-2 in Friday's semi-final.

Sinner, 21, has enjoyed a terrific start to 2023. Since the beginning of the Australian Open, the Italian has only lost three matches – to Stefanos Tsitsipas, Daniil Medvedev and Alcaraz.

He avenged his defeat to Tsitsipas with a straight sets win at the Rotterdam Open, and he has now got one back on Alcaraz after their three-hour war of attrition.

Both players created exactly 12 break point opportunities, and Sinner's 26 unforced errors were only one less than Alcaraz's 27, but the Spanish 19-year-old committed an uncharacteristic nine double faults. The loss snapped Alcaraz's 10-match winning streak.

The victory gives Sinner his second appearance in the Miami Open final after losing the 2021 edition to Hubert Hurkacz, and he now joins Rafael Nadal and Novak Djokovic as the only players to ever reach the final here twice before turning 22.

Sinner will get a chance to avenge his only other loss this year in the final after Daniil Medvedev booked his spot with a 7-6 (7-5) 3-6 6-3 victory over Russian compatriot Karen Khachanov.

Incredibly, Khachanov lost despite hitting 53 winners and only 11 unforced errors, and he ended up edging the total point count 93-88, but he could only convert two of his six break point opportunities, while Medvedev converted two out of four.

The win means Medvedev is the first player since Roger Federer in 2019 to reach the final of both the Indian Wells Open and the Miami Open in the same season, and he is the first since Federer in 2006 to reach five ATP finals before the clay court season begins.

World number one Carlos Alcaraz made it 10 wins in a row in Miami and kept alive his hopes of a rare Sunshine Double as he beat Taylor Fritz in straight sets in Thursday's quarter-finals.

Alcaraz swept aside the 2022 Indian Wells champion 6-4 6-2 in a lopsided Miami Open contest which lasted only 79 minutes, with the Spaniard breaking Fritz in the opening game of both sets.

Both players hit 20 winners, including 11 each on their respective forehands, but Fritz almost doubled Alcaraz' unforced errors count (28-13).

The 19-year-old was impressive from the baseline and overwhelmed Fritz in the end. The American only won 38 per cent on his second serve.

Alcaraz, who won the Indian Wells title a fortnight ago, remains on track to become the eighth male to win the Sunshine Double (Indian Wells and Miami), with Roger Federer the last to achieve that in 2017.

The Spaniard would join Federer (2005, 2006, 2017), Novak Djokovic (2011, 2014, 2015, 2016), Andre Agassi (2001), Marcelo Rios (1998), Pete Sampras (1994), Michael Chang (1992) and Jim Courier (1991) in achieving the Sunshine Double.

Alcaraz will take on Italian 10th seed Jannik Sinner in the semi-finals, after the duo faced off in the Indian Wells last four a fortnight ago, with the Spaniard winning in straight sets.

In-form Daniil Medvedev progressed to the semi-finals with a 6-3 7-5 victory over American qualifier Chrstopher Eubanks, who had enjoyed a dream run in Miami.

Medvedev has a 27-3 record this season and will pursue a fifth straight ATP Tour final when he takes on compatriot Karen Khachanov in the semi-finals.

Khachanov, who made this year's Australian Open semi-finals, defeated Francisco Cerundolo 6-3 6-2 in 76 minutes.

Italian 10th seed Jannik Sinner downed Emil Ruusuvuori to secure his berth in the Miami Open semi-finals along with bringing up his 20th win of the season on Wednesday.

Sinner, who dropped only one point on first serve, won 6-3 6-1 over the Finn in one hour and 16 minutes.

The 21-year-old Italian will face either top seed and defending champion Carlos Alcaraz or 2022 Indian Wells winner Taylor Fritz in the last four. Sinner lost to Alcaraz in the Indian Wells semi-finals a fortnight ago.

Alcaraz and Fritz's Miami quarter-final was postponed to Thursday with persistent rain forcing the evening session in Miami to be cancelled.

The other quarter-finals between 14th seed Karen Khachanov and 25th seed Francisco Cerundolo along with fourth seed Daniil Medvedev and qualifier Christophr Eubanks were also re-scheduled for Thursday.

The Sinner-Ruusuvuori clash was also impacted by a two-hour rain delay, but the Italian prevailed to maintain his perfect record in Miami, having not dropped a set.

"We both played well today but I won the important points," Sinner said. "It's never easy when you are up and you get interrupted, but I came back and played well."

Sinner's run to the Miami semi-finals has seen him drop the fewest games (23) since Rafael Nadal (21) and Novak Djokovic (23) in 2014.

The Italian became the seventh male to reach the semi-finals at both Indian Wells and Miami in a single year before turning 22, joining an elite list in Andre Agassi (1990), Jim Courier (1991), Djokovic (2007), Andy Murray (2007 and 2009), Nadal (2008) and Alcaraz (2022).

Sinner's 2023 record is now 20-4, bettered only by Medvedev (26-3) and Cameron Norrie (21-5).

Carlos Alcaraz does not disagree with Novak Djokovic's assertion of being the best player in the world, as the Spaniard outlined his hope of facing the 22-time major winner at full fitness.

Alcaraz has played Djokovic once before, overcoming the Serbian en route to triumphing at last year's Madrid Open.

The teenager's success in Madrid marked his fifth tour-level title, and his second at an ATP 1000 event.

Earlier in March, Alcaraz claimed his third ATP 1000 title with victory at the Indian Wells Open, seeing the 19-year-old leapfrog Djokovic – who has been unable to compete in the United States due to his COVID-19 vaccination status – back to the top of the world rankings.

Djokovic claimed in interview with The National in February that he was still the best player in the world when at 100 per cent fitness.

Alcaraz, for his part, shares that view.

"Well, it is tough one, but, I have to play against Novak when he's at 100 per cent," Alcaraz told reporters after beating Tommy Paul at the Miami Open, where he is defending champion.

"I would say in Madrid he played really, really well. So it was close. But I agree with him. When he's 100 per cent, probably the best player in the world.

"What Novak has achieved, the level of Novak for example in Australia was unbelievable, really high.

"So as I said before, I really want to play against Novak when he's 100 per cent and I'm sure I'm going to enjoy it. That's all I can say right now."

Alcaraz remains on course for the Sunshine Double – winning both the Indian Wells Open and Miami Open in the same season.

"I try not to think about that but it's difficult," he said. "You know, it's something that I really want. I want to be part of the few players that won the Sunshine Double.

"So for me, would be great to achieve that, but it's something that I try not think about and try to think about day by day, match by match, and that's all. 

"But of course it could be great to be part of that group of few players."

Eleven players, including Djokovic – on four occasions – have won the Sunshine Double, with WTA number one Iga Swiatek the latest to achieve the feat last season.

Second seed Stefanos Tsitsipas was bundled out of the Miami Open in straight sets during Tuesday's fourth round by 2022 US Open semi-finalist Karen Khachanov.

The Russian 14th seed prevailed 7-6 (7-4) 6-4 over Tsitsipas in one hour and 34 minutes, powering 25 winners and making only nine unforced errors, compared to the Greek's 14.

Khachanov's triumph ended a winless 0-6 head-to-head record against Tsitsipas, while it also snapped his own 23-match losing streak against top-10 opponents.

The Russian, who also made this year's Australian Open semi-finals, has qualified for four of his six tour-level events this year.

Khachanov will take on 25th seed Francisco Cerundolo in the quarter-finals, with the Argentinian fighting back to get past Lorenzo Sonego 3-6 6-3 6-2 in just over two hours.

Defending champion and top seed Carlos Alcaraz had less trouble against Tommy Paul, cruising into the quarter-finals with a 6-4 6-4 victory.

Alcaraz won the winners' count 24-9, setting up a quarter-final clash with ninth seed Taylor Fritz, as the Spanish 19-year-old chases a rare Sunshine Double, having won last week's Indian Wells Open.

Fritz progressed after getting past seventh seed Holger Rune 6-3 6-4 in 86 minutes, sending down eight aces and 22 winners for the match.

Fourth seed Daniil Medvedev played late into the evening after a lengthy rain delay in Miami, but made light work of Quinten Halys 6-4 6-2, triumphing just past 1:30am local time.

Medvedev, who is into his third straight Miami quarter-final, will face American qualifier Christopher Eubanks in the last eight after he got past Frenchman Adrian Mannarino 7-6 (7-2) 7-6 (7-5) in another rain-delayed contest.

Italian 10th seed Jannik Sinner knocked off sixth seed Andrey Rublev 6-2 6-4, advancing to face Emil Ruusuvuori after he beat Botic van de Zandschulp 4-6 6-4 7-5.

Top seed and reigning champion Carlos Alcaraz dished out a bagel as he continued his outstanding form with a straight-sets victory over Dusan Lajovic to ease into the Miami Open fourth round on Sunday.

Alcaraz, who triumphed at last week's Indian Wells Open, beat the 76th-ranked Serbian 6-0 7-6 (7-5) in one hour and 32 minutes.

The 19-year-old Spaniard hit 26 winners compared to Lajovic's eight, while Alcaraz also sent down three aces on a 75 per cent first serve percentage.

Alcaraz won the first frame to love in 32 minutes, registering his fourth career bagel at ATP Masters 1000 level, equaling the most by a teenager alongside Rafael Nadal.

The world number one will face 2023 Australian Open semi-finalist Tommy Paul in the fourth round after the American got past 20th seed Alejandro Davidovich Fokina 6-3 7-5.

Third seed and 2022 Miami Open finalist Casper Ruud blew a first-set lead to lose 3-6 6-4 6-4 to Botic Van De Zandschulp.

The Dutchman improved his head-to-head record against Ruud to 3-1 with his first-ever top five win, with the Norwegian left to lament converting only two of 15 break points.

Ninth seed Taylor Fritz progressed into the fourth round with a 6-4 6-4 win over Denis Shapovalov, improving his head-to-head record against the Canadian to 4-5. Fritz committed only eight unforced errors and did not face one break point.

Jannik Sinner maintained his excellent hard-court form with his 18th win this season on the surface, as he defeated Grigor Dimitrov 6-3 6-4 in one hour and 28 minutes. The Italian 10th seed will be Andrey Rublev in the next round.

Sixth seed Rublev needed less than an hour to get past Miomir Kecmanovic 6-1 6-2, while compatriot Daniil Medvedev advanced via a walkover against Alex Molcan due to a right hip injury.

Seventh seed Holger Rune cruised past Diego Schwartzman 6-4 6-2, while Finland's Emil Ruusuvuori got past Taro Daniel 6-3 7-6 (7-3).

World number one Carlos Alcaraz wasted no time in advancing to the Miami Open third round with a straight-sets win over Facundo Bagnis in just 64 minutes, while 13th seed Alexander Zverev suffered an early exit on Friday.

Reigning US Open champion Alcaraz eased past Bagnis 6-0 6-2, firing 12 winners and three aces for the match, committing only 11 unforced errors.

The Spaniard won the first set in 24 minutes, marking the first time he has won an opening frame 6-0 at an ATP Masters 100 event. It was also the first bagel he has dished out since beating Bagnis in Umag last year.

"I knew that I needed to be focused for my first match," Alcaraz said after his win, having triumphed in Indian Wells last week. "To start a new tournament is never easy, different conditions.

"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning, and I'm happy with the way that I played. I try to improve every day."

Alcaraz will face Dusan Lajovic after he beat 30th seed Maxime Cressy 6-4 7-6 (7-2), having knocked off Andy Murray in the first round.

Zverev was the highest seed to bow out on Friday, going down 6-0 6-4 to Japan's Taro Daniel, who beat world number four Casper Ruud last month in Acapulco.

Daniel triumphed in 73 minutes against the German, hitting 17 winners and committing only two unforced errors for the match, while Zverev gave up 18.

The Japanese wild card will meet Emil Ruusuvuori in the third round after the Finn beat 22nd seed Roberto Bautista Agut 6-4 7-6 (7-5) to open up that section of the draw.

Third seed Ruud also had few problems getting past Ilya Ivashka 6-2 6-3 to set up a clash with Botic van de Zandschulp after his three-set win over Alexei Popyrin.

Sixth seed Andrey Rublev overcame J.J. Wolf 7-6 (7-3) 6-4, having been broken in the opening game of what was a tight contest.

Jannik Sinner beat Laslo Djere 6-4 6-2, marking his 16th win out of 20 appearances at the Sunshine Double (Indian Wells and Miami), with only three other players – Novak Djokovic, Alcaraz and Hubert Hurkacz – having as many wins within their first 20 matches.

Ninth seed Taylor Fritz defeated fellow American Emilio Nava 6-4 6-1, and will face Denis Shapovalov in round three after he beat Guido Pella 6-3 3-6 6-3.

American 16th seed Tommy Paul came from a set down to beat Marc-Andrea Huesler 5-7 6-3 6-4, while seventh seed Holger Rune beat Martin Fucsovics 6-3 7-5.

Andy Murray believes Carlos Alcaraz can be a dominant figure in tennis "for as long as he wants" but cautioned against expecting him to challenge the grand slam records of the Big Three.

Roger Federer's haul of 20 slam titles has been overtaken by Rafael Nadal and Novak Djokovic, who both have 22 majors, but those three are streets ahead of every other men's singles player in history.

Next on the list is Pete Sampras with 14 slams, which was itself a total that many once fancied would not be beaten for decades.

Murray was for a time part of a Big Four, until he got left behind by the relentless winning of his three great rivals. Federer has retired, but Djokovic and Nadal may yet have more slam titles in them.

At the age of 19, Alcaraz is already off the mark, winning the US Open last year, and he has jumped back to world number one after winning the Indian Wells Open on Sunday.

Djokovic and Nadal will be big threats to Alcaraz's hopes of triumphing at the French Open, but the young Spaniard is no longer simply the coming player on the ATP. He has arrived, and Murray is convinced Alcaraz is the real deal and poised to stay at the top of the sport for years to come.

"He has an excellent game, an all-around game that I think will translate well onto all surfaces," Murray said.

"He's not the biggest guy, but he can serve big. He's an unbelievable mover, great athlete. Has a lot of variety in his game. Takes the ball on a lot. That's something that you hope that he keeps.

"I know from experience that it's a bit easier playing that way when you're sort of 18, 19, and there's not any scar tissue there. I hope that he maintains that style of play because it's exciting to watch."

The prediction that Alcaraz can be an all-court player, and therefore succeed on grass as well as the hard and clay courts where he has already found success, bodes well for his prospects of stacking up slams.

Murray might have faced Alcaraz in round three at the Miami Open this fortnight, but the veteran Briton, a three-time slam winner and former number one, lost his opener on Wednesday to Serbian Dusan Lajovic.

There have only been two matches on tour between Alcaraz and Murray to date, both coming in the 2021 season when they won one each.

Alcaraz is the defending champion in Miami, and a clear favourite after crushing Daniil Medvedev in the Indian Wells title match. He brings a 14-1 record for the year into the tournament.

"He's obviously so far in his young career doing better than most of the guys that have come in the last eight to 10 years," Murray said.

"I know a lot of people are expecting everyone to win 20-plus grand slams now, like that's sort of normal. I wouldn't predict that for anyone.

"I would imagine he would be right at the top of the game for, well, as long as he wants to play."

Two-time Miami Open champion Andy Murray has been eliminated in the first round of this year's event after a shock 6-4 7-5 loss to world number 76 Dusan Lajovic on Wednesday.

Murray, ranked 53rd in the world, could not find his usual return with Lajovic winning 72 per cent of second-serve points, prevailing in one hour and 38 minutes.

The Serbian claimed only his fourth win out of 16 matches on hard courts since the start of last year, holding his nerve after failing to serve out the match at 5-4 in the second set, converting his third match point in the 12th game.

Lajovic hit 21-14 winners, with Murray committing more unforced errors (15-13). The Serbian converted all three break points he generated.

Former world number six Gael Monfils was forced to retire due to a right wrist injury in his clash with French compatriot Ugo Humbert at 3-3.

Monfils, 36, was playing at only his third event since returning to the ATP Tour following seven months out due to injury.

Argentina's Facundo Bagnis defeated Brazilian qualifier Felipe Meligeni Alves 6-3 1-6 6-4, with his reward a second-round clash with last week's Indian Wells Open winner and top seed Carlos Alcaraz.

World number 50 J.J. Wolf beat world number 48 Alexander Bublik 7-5 6-3 in 79 minutes, earning a second-round clash with sixth seed Andrey Rublev.

World number 74 Martin Fucsovics sent down nine aces as he beat Argentina's Pedro Cachin 6-4 7-6 (7-2) in 107 minutes. Fucsovics will next face seventh seed Holger Rune.

Ilya Ivashka beat Daniel Altmaier 6-2 6-1 to book a second-round clash with third seed Casper Ruud, while Fabio Fognini bowed out, losing 6-4 5-7 6-4 to Jan-Lennard Struff. USA's Brandon Nakashima powered to a 7-6 (7-3) 6-3 victory over Germany's Oscar Otte.

Novak Djokovic does not regret his decision not to be vaccinated against COVID-19, despite losing the world number one ranking.

Djokovic has spent a record 380 weeks at the top of the rankings but was unable to compete in the first two ATP 1000 events of the season – the Indian Wells Open and the Miami Open – after his request for special permission to travel to the United States was declined.

The US currently bars unvaccinated travellers from entering the country, although that policy is set to be scrapped in May. 

With the 22-time grand slam champion unable to feature, Carlos Alcaraz returned to the top of the rankings with victory at Indian Wells.

"I have no regrets," Djokovic told CNN.

"It's a pity that I wasn't able to play in Indian Wells [and] Miami. I love those tournaments. I had plenty of success there. But at the same time, it is the conscious decision I made and I knew that there was always a possibility that I wouldn't go. 

"It is the current state or current situation that I hope will change later this year for the US Open. That is the most important tournament for me on American soil.

"I've learned through life that regrets only hold you back and basically make you live in the past and I don't want to do that. 

"I also don't want to live too much in the future. I want to be as much as in the present moment, but of course, think about the future and create a better future."

Alcaraz, who won the US Open in 2022, romped to last week's title at Indian Wells with a comprehensive 6-3 6-2 victory against Daniil Medvedev in the final.

"I congratulate Alcaraz," Djokovic said. "He absolutely deserves to come back to number one."

Djokovic's attention will now turn to the clay season in Europe as he gears up to try and win a third French Open title.

"I'm as enthusiastic as ever, as motivated as ever for the sport, my family, my foundation, all the projects and everything I'm doing off the court," he added.

"The dignity, and integrity, and staying true to myself, and my beliefs and my rights are above everything."

Jack Draper has pulled out of the Miami Open due to an abdominal injury that forced him to retire from his match against Carlos Alcaraz at Indian Wells.

The Briton suffered a tear to his oblique muscle during his fourth round encounter with the Spaniard, forcing him to bring the match to a premature end in the second set.

While Alcaraz went on to win the tournament and reclaim his position as world number one, Draper is now set for a spell on the sidelines.

The 21-year-old has decided to withdraw from Miami, in order to focus on making a full recovery rather than risk aggravating the issue.

The world number 43 struggled for fitness during the 2021 season, but played 22 events last year and reached the quarter-finals of the Canadian Open.

Alcaraz won his first ATP Masters 1000 title in Miami last year by beating Casper Ruud in the final. 

After being awarded a bye into the second round, he will face either Facundo Bagnis or a qualifier and could take on Andy Murray in round three as he eyes a Sunshine Double.

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.
