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.

Seventh seed Tommy Paul claimed a spot in the Mexican Open final after proving too good for countryman Taylor Fritz in the longest match in Acapulco history on Friday.

Paul edged the third seed 6-3 6-7 (2-7) 7-6 (7-2) in three hours and 29 minutes in their semi-final clash in Acapulco.

World number 23 Paul actually generated a match point late in the second set but spurned his initial chance, then waiting another two hours before winning in the third-set tie-break.

Paul let match point slip at 5-4 in the second set and had to rally back from 3-1 down in the third, but triumphed on his fourth match point.

"I couldn't be happier," Paul said. "The goal for this year was to get the ranking up and get more trophies. I only have one trophy on Tour between singles and doubles.

"You don't get trophies unless your in the final, and hopefully I can play another good match tomorrow and get the winner's trophy."

The 2023 Australian Open semi-finalist will take on Alex de Minaur in Saturday's decider, after he defeated Holger Rune 3-6 7-5 6-2 in two hours and 50 minutes.

In the Chile Open, local Nicolas Jarry progressed into the semi-finals with a 3-6 6-3 6-4 win over German qualifier Yannick Hanfmann. Jarry will face Spaniard Jaume Munar after he won 6-3 3-6 6-2 over Thiago Monteiro.

Third seed Sebastian Baez got past Laslo Djere 7-6 (7-4) 6-4, setting up a semi-final date with Tomas Martin Etcheverry after he won 6-1 6-2 over Dusan Lajovic.

World number five Taylor Fritz showed why he is the highest seed still standing at the Mexican Open after a strong 6-3 6-4 win in Thursday's quarter-final.

Fritz, the third seed, faced sixth seed and world number 15 Frances Tiafoe, and did not allow a single break of serve en route to the 96-minute victory.

He will now face compatriot Tommy Paul in an all-American semi-final after the world number 23 prevailed 6-2 6-2 against Mackenzie McDonald.

The win was Paul's 10th from his past 12 matches, with one of those two losses coming against Novak Djokovic.

Australia's Alex De Minaur is through to the other semi-final after making light work of Japan's Taro Daniel 6-2 6-2 in a surprisingly one-sided contest, considering Daniel was coming off a victory over world number four Casper Ruud.

De Minaur will face Holger Rune after the 19-year-old capitalised on Matteo Berrettini not being at 100 per cent, jumping out to a perfect 6-0 1-0 start before the Italian retired hurt.

Meanwhile, Chile Open second seed Francisco Cerundolo missed out on a potential chance to face his younger brother after going down 6-3 3-6 6-3 against Tomas Martin Etcheverry.

He was one win away from doing his part to set up a quarter-final showdown with Juan Manuel Cerundolo, but the 21-year-old Argentine also did not hold up his end of the bargain, falling 6-2 2-6 7-6 (7-2) to Serbia's Dusan Lajovic.

Laslo Djere ensured it would be a good day for the Serbians with a 7-5 7-5 handling of Italy's Riccardo Bonadio, and he will face third seed Sebastian Baez in the quarter-final after he eliminated hometown hero Cristian Garin 6-4 6-3.

Second seed Casper Ruud suffered a shock three-sets second-round defeat to Japan's Taro Daniel at the Mexican Open in Acapulco on Wednesday.

The 2022 US Open and French Open runner-up had struggled past Guido Andreozzi in the first round and followed up that up with a 7-5 2-6 7-6 (7-5) loss to Daniel.

The Japanese qualifier, ranked 125th in the world, won in just under three hours, winning the final three points of the deciding tie-break after Ruud led 5-4.

Ruud had more winners (38-32) but committed 30 unforced errors compared to Daniel's 12.

Taylor Fritz cruised into the last eight with a 6-4 6-4 win over Canada's Denis Shapovalov, setting up a quarter-final with sixth seed Francis Tiafoe, who eased past Feliciano Lopez 6-2 7-6 (8-6).

Fourth seed Holger Rune was too strong for Nuno Borges 6-0 6-2 inside an hour, while eighth seed Alex De Minaur crushed Jacopo Berrettini in just over an hour 6-1 6-0.

Top seed Lorenzo Musetti was a surprise second-round loser at the Chile Open with Jaume Munar triumphing 6-4 6-4 in one hour and 31 minutes.

Fourth seed Diego Schwartzman also bowed out, going down 6-4 4-6 7-6 (7-2) to local Nicolas Jarry.

Jarry will face Yannick Hanfmann in the quarter-finals, while Munar will take on Thiago Monteiro.

Taylor Fritz was forced to come from behind to claim a three-set victory over John Isner in the opening round of the Mexican Open in Acapulco on Monday.

Fritz was among the seeds to progress, alongside Casper Ruud, Holger Rune, Francis Tiafoe and Tommy Paul.

The third seed lost the opening set in 29 minutes but rallied back to win 3-6 6-3 6-4 in one hour and 49 minutes over the big-serving world number 38 Isner.

Fritz claimed his first break of the match in the 17th game before levelling things up at one set each, before breaking Isner at 4-4 in the third and serving out for victory.

The win means Fritz will take on Canada's Denis Shapovalov in the second round after he beat Miomir Kecmanovic in three sets, with the American looking to go one better after being runner-up in Acapulco in 2020.

Second seed Ruud found himself in an almighty battle with Argentina's Guido Andreozzi and eventually prevailed 6-4 4-6 7-6 (7-2).

World number four Ruud, ranked 338 places above his opponent, was broken in the first game of each set but dug deep to get the job done in a little under three hours. 

Fourth seed Rune got past 2023 Australian Open quarter-finalist Ben Shelton 6-7 (7-9) 6-4 6-2.

Sixth seed Tiafoe overcame Japan's Yoshihito Nishioka 7-6 (8-6) 6-4 while 2023 Australian Open semi-finalist Paul beat Emilio Gomez 6-1 7-6 (7-4).

Defending champion Pedro Martinez was bundled out of the Chile Open in the first round after losing 6-2 6-0 to German qualifier Yannick Hanfmann.

Jaume Munar progressed to set up a second-round clash with top seed Lorenzo Musetti after winning 6-0 6-7 (4-7) 7-6 (7-5) against Alejandro Tabilo.

Taylor Fritz showed why he is ranked top-10 in the world and rising after beating Miomir Kecmanovic 6-0 5-7 6-2 in Sunday's final of the Delray Beach Open.

Fritz, 25, came into the tournament sitting at a career-best rank of seventh, and he did not lose his first set in Delray Beach until the final.

The top seed, Fritz was nearly perfect in the opening set, hitting 15 winners with only one unforced error and taking 72 per cent (28-of-39) of the total points. Kecmanovic did not hit a single winner in the set.

The 23-year-old Serbian showed far more fight in the second, and after saving all three of Fritz's break-point opportunities – including one match point – Kecmanovic capitalised on his one and only break-point chance of the match to force a third set.

But the mistakes crept back into the underdog's game, shooting himself in the foot with a pair of double faults and more unforced errors than winners.

Fritz took full advantage, securing two breaks down the stretch to run away with the victory and his first title of 2023.

After winning just one of his first six finals on the ATP Tour, Fritz has now won the past four finals he has reached.

Carlos Alcaraz clinched a berth in the Argentina Open in his first tournament back from injury with a straight-sets victory over Spanish compatriot Bernabe Zapata Miralles on Saturday.

Alcaraz, who had not played since the Paris Masters in early November due to abdominal and right leg injuries, triumphed 6-2 6-2 in one hour and 17 minutes.

The 19-year-old Spaniard will face second seed Cameron Norrie in Sunday's decider, with the Briton needing almost two hours to overcome Peruvian qualifier Juan Pablo Varillas 7-6 (7-5) 6-4.

"It’s a really special moment for me," Alcaraz said. "I was a little bit down after the injury, so I had to recover in those four months the confidence and the rhythm.

"Coming back for my first tournament of 2023 and making the final is so special for me."

Alcaraz has won all three matches at the Argentina Open, dropping only one set against Laslo Djere in his return match in the second round.

Taylor Fritz beat countryman Mackenzie McDonald for a spot in the Delray Beach Open final in Florida, fighting back from a break down in the second set to win 6-3 7-6 (8-6) and a secure a berth in his 10th career final.

Fritz, the top seed at Delray Beach, will take on Serbia's Miomir Kecmanovic in the decider after he won 7-6 (10-8) 3-6 6-2 over Moldova's Radu Albot.

World number two Carlos Alcaraz was too good in his Argentina Open quarter-final on Friday, defeating Dusan Lajovic 6-4 6-2.

The 19-year-old is playing in his first tournament of the year, and after dropping a set in his opener against Serbia's Laslo Djere, he had fewer problems against Djere's compatriot.

Alcaraz will play Bernabe Zapata Miralles in an all-Spanish semi-final after he eliminated Buenos Aires' own Francisco Cerundolo 6-3 6-7 (4-7) 6-3.

England's Cameron Norrie had to come from a set behind for the second match in a row to knock out Argentina's Tomas Martin Etcheverry 5-7 6-0 6-3, and he will meet Peru's Juan Pablo Varillas in the other semi-final.

Varillas collected arguably the biggest win of his career against world number 20 Lorenzo Musetti, and he is now two wins away from his first ATP Tour title.

Meanwhile, top seed and world number seven Taylor Fritz is through to the semi-final of the Delray Beach Open after fending off the challenge of veteran Adrian Mannarino 7-6 (10-8) 6-4.

Fritz has lost his past two meetings with Mackenzie McDonald, and he will get a chance at redemption after McDonald joined him in the semi-final with a 3-6 6-3 6-4 triumph over Michael Mmoh.

Fourth seed Miomir Kecmanovic joins Fritz as the only seeded players to reach the semi-finals after he saw off Marcos Giron 7-6 (7-5) 6-3, while second seed Tommy Paul was upset as a heavy favourite against Romania's Radu Albot 6-2 6-2.

Lorenzo Musetti won his opening match at the Argentina Open in comfortable fashion, defeating hometown hero Pedro Cachin 6-2 6-3 on Thursday.

World number 20 Musetti is still just 20 years old, making him the third-youngest player inside the top-40. The only younger players are 19-year-olds Carlos Alcaraz (world number two) and Holger Rune (world number nine).

The talented Italian has two ATP Tour titles to his name, but none outside of Europe, and he will hope to change that after he advanced to the quarter-finals in Buenos Aires.

Musetti will play Peru's Juan Pablo Varillas next after he prevailed 6-4 6-4 against former world number three Dominic Thiem.

Fifth seed Francisco Cerundolo did his part to set up an all-Argentine quarter-final clash after dominating Jaume Munar 6-2 6-1, but compatriot Diego Schwartzman could not hold up his end of the deal, falling 6-1 6-3 to Spain's Bernabe Zapata Miralles.

Meanwhile, world number seven Taylor Fritz made a winning start to his Delray Beach Open campaign, defeating Ecuador's Emilio Gomez 6-4 6-3.

Fritz will play France's Adrian Mannarino in the quarter-final after the 34-year-old veteran eliminated 24-year-old American J.J. Wolf 7-5 6-2.

Second seed Tommy Paul was too strong for Denis Kudla in a 6-3 6-4 triumph, and he will play Radu Albot for a place in the semi-final after the Romanian emerged the 6-4 6-4 victor against Australia's Aleksandar Vukic.

There is guaranteed to be an Argentine winner of the Cordoba Open on Saturday, while Taylor Fritz was stunned in Dallas.

Federico Coria, seeded sixth, overcame reigning champion and 2021 runner-up Albert Ramos-Vinolas 6-4 7-6 (7-2) after over two-and-a-half hours of action.

The world number 67, who is into his second ATP Tour-level final and is set to rise into the top 50 of the rankings, has dropped just a single set in the tournament.

Sebastian Baez, eight years Coria's junior, is aiming for his second title after winning in Estoril last year.

The 22-year-old fourth seed defeated Hugo Dellien 6-4 6-4.

This will be the fourth singles final of Baez's career, though his first on home soil.

"It means a lot, but [it brings] confidence," said Baez.

"I have my people here, my friends, my family, everything, so that is a big motivation for me."

While Coria and Baez have just five previous final appearances between them, John Isner advanced to a 31st Tour-level showdown of his career as he beat fellow American J.J. Wolff at the Dallas Open.

Playing in his home city, 37-year-old Isner came from behind to prevail 3-6 7-5 7-6 (7-4).

Isner offered up eight break points, but saved seven of them to frustrate Wolff.

"I saved a lot of break points with unreturnable serves," Isner said. "Without that I would have been dusted off the court 6-3, 6-4. I'm of course very fortunate to have that weapon in my pocket, and I needed every bit of it today.

"It was an absolute battle, so I'm pretty tired. But I'm absolutely ecstatic to be in the final tomorrow here in Dallas."

Asked how he was faring up after his long tussle with Wolff, Isner quipped: "Truthfully, it feels terrible right now. I'm 38 in April. It's not getting any easier. I started off a little slow, a little sluggish, but in the third set I actually felt the best I felt the whole match.

"I had a lot of adrenaline there at the end and I was able to hold my nerve and win. Right now the name of the game is recovery."

Isner will be the favourite in the final, after top seed Fritz surrendered a lead in a 6-7 (3-7) 7-5 6-4 loss to Wu Yibing.

World number eight Taylor Fritz is two wins away from his first title of the season after surviving a tough test against Marcos Giron 7-6 (9-7) 3-6 6-3 in Friday's quarter-final at the Dallas Open.

Fritz, who at 25-years-old is seeking the fifth ATP singles title of his career, allowed seventh-seed Giron only one break point opportunity for the entire match. Fritz himself only created two such opportunities, and further illustrating the closely-fought nature of the battle, Fritz edged the total point count 86-85.

With the win, Fritz booked his place against China's Yibing Wu in the semi-final after the 23-year-old defeated 34-year-old French veteran Adrian Mannarino 6-3 6-4.

The other semi-final will be an all-American showdown after J.J. Wolf upset second seed Frances Tiafoe 4-6 6-3 6-4, and 37-year-old John Isner proved too much for Ecuador's Emilio Gomez in a 7-6 (10-8) 7-5 victory.

Meanwhile, Spain's Albert Ramos-Vinolas is one match away from a final in his home country after defeating Joao Sousa 6-4 2-6 6-1 in the quarter-final of the Cordoba Open.

Ramos-Vinolas will play Argentina's Federico Coria for a spot in the decider after he emerged victorious 6-3 3-0 (ret) against compatriot Francisco Cerundolo.

Heading into the quarter-finals, Francisco and his brother Juan Manuel Cerundolo were on a collision course to meet in the final, but now both are eliminated after 21-year-old Juan Manuel fell 6-7 (5-7) 6-4 6-0 to Bolivia's Hugo Dellien.

Dellien will play fourth seed Sebastian Baez in the other semi-final after eliminating Chile's Tomas Barrios Vera 6-1 3-6 6-1.

Top seed and world number eight Taylor Fritz made a winning start to his Dallas Open campaign on Thursday, eliminating Jack Sock 7-6 (7-5) 6-4.

In an all-American showdown, Fritz played a near-flawless match, converting 91 per cent of his accurate first serves into points while not allowing Sock a single break point opportunity.

Fritz will face seventh seed Marcos Giron in the quarter-final after the American defeated Germany's Oscar Otte 6-4 6-3, while the USA's John Isner also advanced past Germany's Daniel Altmaier 6-3 7-6 (7-1).

Earlier in the day, Serbian fourth seed Miomir Kecmanovic was upset by Ecuador's Emilio Gomez 2-6 7-6 (7-4) 6-4 to earn a crack at Isner in the quarter-finals.

Meanwhile, the top seed fell at the Cordoba Open as red-hot 21-year-old Juan Manuel Cerundolo shocked his Argentinian compatriot Diego Schwartzman 7-6 (8-6) 6-1.

It continues a remarkable run for Cerundolo – the defending champion in Cordoba – who has begun 2023 with 14 wins from his first 15 matches, while his older brother Francisco Cerundolo also advanced with a 6-3 3-6 7-5 win over Federico Delbonis.

If the two brothers both win their next two matches, they will meet in the final.

For the first time in 20 years, four or fewer of the top eight seeds in the men's singles will progress to the fourth round of the Australian Open.

Daniil Medvedev's defeat to Sebastian Korda on Friday meant he joined Casper Ruud, Taylor Fritz and defending champion Rafael Nadal in heading home early from the season's first grand slam.

According to Opta, it is the first time since 2003 that the round of 16 in Melbourne will include four or fewer of the top eight players in the competition.  

Nine-time champion Novak Djokovic, meanwhile, is struggling with injury ahead of his third-round tie with Grigor Dimitrov on Saturday, while world number six and fifth seed Andrey Rublev faces a tough test against Dan Evans.

Stefanos Tsitsipas is sure of his place in round four after the Greek third seed beat Tallon Griekspoor in straight sets. Felix Auger-Aliassime will go up against Jiri Lehecka for a place in the last eight.

Taylor Fritz and Alexander Zverev were sent packing from the Australian Open as wildcard Alexei Popyrin and lucky loser Michael Mmoh sprang major shocks.

Australian Popyrin said he was living a dream after beating the fancied Fritz in an epic second-round match lasting four hours and two minutes on John Cain Arena.

American Mmoh, whose mother has Australian citizenship, knocked out former world number two Zverev just moments later on Margaret Court Arena.

Their exits followed the shock defeat for second seed Casper Ruud earlier in the day, as Novak Djokovic's half of the draw lost a host of big names.

Wildcard Popyrin won 6-7 (4-7) 7-6 (7-2) 6-4 6-7 (6-8) 6-2 against American eighth seed Fritz, revelling in the chants of "Popy" from the crowd afterwards.

The 23-year-old was close to tears, his voice breaking, after reaching the third round of a grand slam for the fifth time.

"This win, it means so much to me," Popyrin said. "I had the toughest year last year, didn't win many matches. I've won as many matches this year as I won in the whole of last year, and it's only January.

"Pre-season I put my head down and worked as hard as I could. I don't want that feeling I had last year ever again.

"I wrote that down to myself in my head, and I'm going to keep working, I'm going to keep pushing, I'm going to keep trying to go all the way."

Addressing the crowd, Popyrin added: "I love this feeling. I want more of this feeling. I want you guys to have this feeling more. I love you guys so much, thank you."

He is coached by former top-20 star Xavier Malisse and felt the Belgian's influence against Fritz.

"I was playing four hours, and me and my coach were locked in, it was like two against one against Fritzy. We had the same thoughts all the time," Popyrin said. "This is the dream for me and I don't want to wake up at all."

Mmoh was beaten by Aleksandar Vukic in the final round of qualifying but received a call into the draw at the last minute, after a late withdrawal, allowing him to cancel a flight home.

The world number 109 will face fellow American JJ Wolf next, for a place in round four, having ousted 12th seed Zverev 6-7 (1-7) 6-4 6-3 6-2.

Mmoh's father, Tony, represented Nigeria and won a match at the Australian Open in 1988.

"Life is crazy," Mmoh said. "Right when you think everything is looking dim, everything is looking dark, there's light at the end of the tunnel.

"My week is proof of that. I could easily have been in the States, was ready to be in the States, had my bag packed, my flight booked, I was meant to leave yesterday morning. The fact I'm playing Margaret Court is insane.

"If you look at my box over there, there's about five to seven Aussies. I used to come every single Christmas to visit them, unfortunately my mum couldn't be here, I feel like I'm half Australian because of them and I love you guys. This is like my second home now so might as well make it a homecoming.

"It's the biggest win of my career hands down. Coming out I felt the nerves a little bit. I settled down at the end of the first, and at that point I told myself I shouldn't even be here. I told myself on match point if I get a chance just go for it, because I shouldn't even be here."
