Cameron Norrie was not the only opponent Carlos Alcaraz had to overcome in the Argentina Open final, as he battled feelings of guilt after not doing "the right things" to recover from injury.

Alcaraz made it one title from one tournament in 2023 as he overcame Norrie 6-3 7-5 in Buenos Aires on Sunday.

Last year's US Open champion dropped just one set through the tournament as he marked his return to action in style, with the 19-year-old having missed the Australian Open due to a hamstring issue.

Alcaraz had not featured since November, and the world number two admitted he did not feel his application during his extended break was always as good as it should have been.

"This trophy is special. During those four months I had a hard time and I didn't do the right things off the court, and I felt a bit guilty after the injury," Alcaraz said.

"Fighting against this is not easy. Coming here, my first tournament after four months, and winning the first tournament since the US Open is very special for me."

Alcaraz won seven games on the bounce to swing the final in his favour, and believes he hit peak performance during the match.

"I felt very comfortable playing the final," Alcaraz added.

"I knew that it was going to be really difficult. I started really focussed on what I had to do at the beginning, my game, my level. 

"This is the level that I have to play in finals."

Alcaraz has already collected seven titles in his young career, with five of those coming on clay.

His idol and compatriot Rafael Nadal won 13 clay-court tournaments prior to turning 20.

Combined with Alcaraz's haul, that total of 18 betters the 13 managed by all other players combined on the ATP Tour in the 21st century before turning 20.

Alcaraz is now set to play in the Rio Open, where he is the reigning champion, this week.

In his first tournament since a four-month injury layoff Carlos Alcaraz went all the way and defeated Cameron Norrie 6-3 7-5 in the Argentina Open final.

Alcaraz, 19, became the youngest player to ever reach the world number one ranking in September, and with his victory in Buenos Aires he now has seven ATP Tour singles titles to his name.

After knocking off some rust in a close three-set opening match against Laslo Djere, Alcaraz advanced to the final following straight sets victories over Dusan Lajovic and Spanish compatriot Bernabe Zapata Miralles.

Against Norrie, Alcaraz played an exceptionally tight first set, winning 73 per cent (16-of-22) of his service points while not allowing his opponent a single break point opportunity.

He broke twice in the opening set and secured another quick break to begin the second, jumping ahead 3-0 as he threatened to run away with the match.

Norrie did not lay down, recovering from 5-2 down to tie things up at 5-5, but Alcaraz would not allow it to reach a tie-breaker as he finished the match with another break of serve.

The 250 ranking points on offer to the winner pulls Alcaraz to within striking distance of Novak Djokovic as he looks to reclaim his spot as world number one.

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.

Carlos Alcaraz overcame a second-set hiccup to win on his return to the ATP Tour over Laslo Djere in the second round at the Argentina Open on Wednesday.

Alcaraz, who rose to the world number one ranking after last year's US Open triumph, won 6-2 4-6 6-2 in two hours and one minute over the Serbian in Buenos Aires.

The match marked top seed Alcaraz's first since losing to Holger Rune in the Paris Masters quarter-finals, having missed last month's Australian Open following abdominal and hamstring injuries.

The Spanish 19-year-old displayed his trademark forehand on occasion, while he was at his tenacious best, saving six of seven break points generated by Djere.

"It's a great feeling to win again," Alcaraz said post-match. "It's been a long time for me with no competition, with no matches, just recovering. Finally, I got my first win of 2023."

Alcaraz will face Serbian qualifier Dusan Lajovic next after he won 6-3 6-1 over local Camilo Ugo Carabelli.

Second seed Cameron Norrie was pushed for three hours by Argentinian wild card Facundo Diaz Acosta before prevailing 4-6 7-5 7-6 (8-6). Diaz Acosta got within two points of victory on three occasions but could not capitalise.

Norrie will face another Argentinian in the third round, with Tomas Martin Etcheverry progressing with a 4-6 6-1 6-2 win over Roberto Carballes Baena.

Third seed Denis Shapovalov was a shock second-round casualty at the Delray Beach Open after going down in here sets to Michael Mmoh on Wednesday.

The American, who is ranked 87th in the world, triumphed 7-5 3-6 6-3 in two hours and 20 minutes at the event in Florida.

The Canadian committed 30 unforced errors across the match compared to Mmoh's 16. Shapovalov also generated 10 break points but only capitalized on two, while Mmoh converted three of five.

Mmoh will take on countryman Mackenzie McDonald who won 6-3 3-6 6-2 over fifth seed Yoshihito Nishioka.

Fourth seed Miomir Kecmanovic cruised past qualifier Nuno Borges 6-3 7-5, while Marcos Giron also progressed in straight sets over Matija Pecotic.

Cameron Norrie missed the chance to cap his New Zealand homecoming as he was beaten 4-6 6-4 6-4 by Richard Gasquet in the Auckland Open final on Saturday.

Norrie grew up in Auckland, and the British number one reached his first ATP Tour-level final in the city in 2019.

But despite repeating that feat and then winning the opening set of Saturday's final, Frenchman Gasquet roared back to lift his first title on the ATP Tour since 2018.

After they split the opening two sets, Norrie looked to be on the way to victory when he held a 4-1 lead in the decider.

But 36-year-old Gasquet rattled off five straight sets, including two breaks of serve, to shock the second seed and become the oldest champion in the Auckland Open's 66-year history.

"It's an amazing title for me, especially now at my age," Gasquet told a post-match news conference. "I really didn't think I would win again.

"I'm 37 this year, so when I came here last week, if you were to tell me next Saturday you will win here, I wouldn't believe it."

Norrie gets his Australian Open campaign underway against wildcard Luca van Assche on Monday, while Gasquet will play fellow Frenchman Ugo Humbert in the first round.

At the Adelaide International 2, Kwon Son-woo defeated Roberto Bautista Agut 6-4 3-6 7-6 (7-4) to take the crown.

Bautista Agut, who knocked out defending champion Thanasi Kokkinakis in the semi-finals, hit back from losing the opening set to level the game with a strong second stanza.

The deciding set went all the way to a tie-break as both players lost two of their service games, but with Kwon 5-4 up in the pivotal tie-break, the world number 84 found two breaks of serve to complete the victory.

The win was Kwon's second ATP Tour title and first since lifting the Astana Open trophy in 2021, while he becomes the first South Korean to win multiple Tour-level titles.

Cameron Norrie will get a chance to cap his New Zealand homecoming with a title at the Auckland Open.

The British number one, who spent much of his childhood in New Zealand and Auckland specifically, reached his first ATP Tour-level final in the city in 2019, and has repeated that feat this time out.

Norrie made light work of Jenson Brooksby on Friday, winning 6-3 6-4.

He will face Richard Gasquet, who progressed via walkover due to Constant Lestienne's withdrawal through injury, in Saturday's showdown.

Norrie has won all six of his matches this season, three in Auckland and three at the United Cup, where he beat Rafael Nadal.

"It was an absolute battle with Jenson. A lot of long rallies and I know how well he competes, so it was nice to get it done in straight sets," said Norrie.

"He puts the ball in such awkward parts off the court and I had to come up with a lot of really tough shots on the run and a lot of big passes.

"I was able to serve it out and stay really calm and get over the line, but he's a great player."

At the Adelaide International 2, defending champion Thanasi Kokkinakis fell just short of reaching the final again.

He battled back from a set down to force a decider against Roberto Bautista Agut, but it was the Spaniard who prevailed 7-6 (7-4) 3-6 6-3.

Bautista Agut will face Soonwoo Kwon in the final, after the world number 84 defeated Norrie's compatriot Jack Draper 7-6 (8-6) 6-7 (2-7) 6-3.

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).

The other semi-final will be an all-French battle between Richard Gasquet and Constant Lestienne, who both came from a set down to see off David Goffin and Laslo Djere respectively.

Thanasi Kokkinakis is on a roll again at the Adelaide International 2 where the hometown hero and defending champion marched into the semi-finals on just two hours' sleep.

The Australian wildcard saw off Serbian sixth seed Miomir Kecmanovic 6-3 6-7 (4-7) 6-1 on Thursday to set up a semi-final against Spain's Roberto Bautista Agut.

Kokkinakis had a stellar run to the title at this tournament 12 months ago, beating John Isner and Marin Cilic before knocking over Frenchman Arthur Rinderknech in the final.

A first-round exit followed at the Australian Open, although he memorably won the doubles title with Nick Kyrgios. Kokkinakis struggled for the rest of the year, with his ranking currently at 110.

Kokkinakis said after his latest win: "I didn't sleep much last night. I reckon I got to sleep at about five and maybe slept for a couple of hours.

"I just couldn't sleep for whatever reason, so I was trying to conserve energy. I didn't want to use it too much. I had a couple of Monsters [energy drinks] before I started and tried to get going.

"When I'm serving well my whole game follows, and then when my forehand gets going I think I've been hitting my backhand really well this week. If I'm doing those three things, it's a good recipe.

"I grew up on this court when I was eight, nine, 10 years old. I showed up last year, and hopefully I can ride the wave with you guys and keep it going."

Fourth seed Bautista Agut beat compatriot Alejandro Davidovich Fokina 6-3 6-2, while the other Adelaide semi-final will see British player Jack Draper tackle South Korean Kwon Soon-woo.

Draper, who has been drawn to face Rafael Nadal in round one of the Australian Open, beat Russian third seed Karen Khachanov 6-4 7-6 (7-3), while Kwon saw off Swedish qualifier Mikael Ymer 6-1 6-2.

At the Auckland Open, second-seed Briton Cameron Norrie beat American Marcos Giron 6-1 6-7 (5-7) 6-2 to set up a last-four clash with another player from the USA, Jenson Brooksby, who edged past France's Quentin Halys 7-6 (7-3) 7-6 (7-2).

The other semi-final will be an all-French battle between Richard Gasquet and Constant Lestienne, who both came from a set down to see off David Goffin and Laslo Djere respectively.

Gregoire Barrere withstood a barrage of aces from John Isner and a change of court triggered by Cyclone Hale as he upset the American sixth seed at the Auckland Open.

French qualifier Barrere and US veteran Isner were forced indoors by the adverse weather threat in New Zealand, with the entire Tuesday schedule taking place on inside courts and without spectators.

Despite Isner rifling down 28 aces to move 10 away from becoming the first man to post 14,000 in ATP tour and grand slam events, Barrere stuck with him and pulled off a 6-7 (3-7) 7-6 (7-5) 6-3 victory.

He snatched the only break of the match in game eight of the deciding set, before serving out for victory, with the world number 88 firing down 10 aces himself across the contest.

Argentine seventh seed Sebastian Baez also fell at the last-32 stage, bowing out 7-6 (7-1) 6-1 to American wildcard Ben Shelton.

Serbian Laslo Djere set up a second-round clash with top seed Casper Ruud by edging out Spain's Jaume Munar 3-6 6-1 7-6 (7-4), while Czech Jiri Lehecka will face second seed Cameron Norrie next after sinking Brazilian fellow qualifier Thiago Monteiro 6-3 7-5.

Ruud and Norrie received first-round byes.

At Adelaide International 2, American eighth seed Tommy Paul battled past Australian Christopher O'Connell 6-4 7-5, setting up an appetising second-round clash with Britain's Jack Draper, who won through on Monday.

There was a home success for the Australian crowd to cheer, though, as qualifier John Millman, who beat Roger Federer at the 2018 US Open, this time dug deep for a 4-6 6-3 7-6 (8-6) win against Spain's Albert Ramos-Vinolas.

Iga Swiatek dragged Poland into the semi-finals of the United Cup with inspired performances in her singles and doubles matches against Italy.

Poland trailed after Lorenzo Musetti and Matteo Berrettini secured wins against Daniel Michalski and Hubert Hurkacz respectively, only for Swiatek and Magda Linette to level things with respective singles victories over Martina Trevisan and Lucia Bronzetti.

That sent the Brisbane city final to a decider in the mixed doubles, which Swiatek and Hurkacz won with ease 6-1 6-2 against Musetti and Camilla Rosatello, though there was a pause in the second set to dry rainfall on the court.

Despite defeat, Italy also advanced to the final four as the city finals loser with the best record.

It was more routine in Sydney as the United States eased to a 4-1 win against Great Britain.

Madison Keys came from a set down to beat Katie Swan, while Jessica Pegula eased past Harriet Dart 6-2 6-0 after Cameron Norrie had defeated Taylor Fritz in three sets.

Despite going a set behind, Frances Tiafoe came back to beat Dan Evans 3-6 7-5 6-3 to clinch the win for his country, before Pegula and Fritz added some gloss after beating Dart and Evans in the mixed doubles.

The third city final in Perth included a thriller as Greece's Stefanos Tsitsipas beat Borna Coric 6-0 6-7 (4-7) 7-5. Donna Vekic had no trouble getting Croatia on the board as she eased past Despina Papamichail 6-2 6-0.

Maria Sakkari put Greece 2-1 ahead when she beat Petra Martic 6-3 6-3, but Borna Gojo defeated Stefanos Sakellaridis in straight sets to make it 2-2.

However, Greece secured the win and their place in the last four after the pairing of Sakkari and Tsitsipas saw off Martic and Gojo 7-6 (8-6) 6-4.

Greece will take on Italy in the semi-finals, while Poland face the USA, with both taking place in Sydney on Friday.

Rafael Nadal shot down questions over his potential retirement after losing to Cameron Norrie at the United Cup, saying he is "here to continue playing tennis".

As part of his preparation for next month's Australian Open, 22-time grand slam winner Nadal fell to a 3-6 6-3 6-4 defeat to Norrie as Great Britain seized a 2-0 lead over Spain in Sydney.

Norrie had not won a set against Nadal in their previous four matches, and the 36-year-old was asked afterwards how much longer he planned to continue before calling it a day on his historic career.

"Every time I come to a press conference, it seems like I have to retire," Nadal told reporters. "You're very, very interested in my retirement.

"At the moment, that's not the case. When this day comes, I'll let you know.

"But don't go on the subject of retirement because I'm here to continue playing tennis."

With just over two weeks until Nadal's Australian Open title defence gets underway, the Spaniard knows he will have to improve on his performance against Norrie, saying: "I need to be faster physically and a little more solid.

"There is a way to improve, but I have time before the Australian Open starts in two weeks."

While Nadal's shaky performance against Norrie could cause concern over whether he can defend his crown in Melbourne, he was keen to credit the British number one, stating: "He is a top player.

"He didn't impress me much because I know he is very good. He did a lot of things well, very solid, without mistakes, serving well. I can do things better and I need to."

Nadal will be in action again at the United Cup on Sunday, taking part in a doubles match with Paula Badosa against Daniel Evans and Harriet Dart.

Rafael Nadal's United Cup campaign began with defeat against Cameron Norrie as Great Britain established a 2-0 lead over Spain in Group D.

The 22-time grand slam winner surrendered a first-set lead before going down 3-6 6-3 6-4 against the world number 14, who secured his first victory in five meetings.

Norrie, who became only the second Briton after Andy Murray to beat the Spaniard, set the tone for his team, with Katie Dart also coming from behind to deny Nuria Parrizas Diaz 3-6 6-1 6-2 later on.

Meanwhile, Germany's Alexander Zverev lost in straight sets on his return to ATP action, going down 6-4 6-2 to Jiri Lehecka of the Czech Republic, who went 2-0 up in the tie after Marie Bouzkova defeated Jule Niemeier 6-2 7-5.

World number one Iga Swiatek got Poland off to a flying start against Kazakhstan in Brisbane with a commanding 6-1 6-3 victory over Yulia Putintseva, but defeat for Daniel Michalski against Timofey Skatov leaves the Group B tie finely poised.

Brazil enjoyed a flawless start against Norway in Group E. Beatriz Haddad Maia was a 6-4 6-2 winner over Malene Helgo, and Felipe Meligeni Alves overcame Viktor Durasovic 6-3 6-3.

The spoils were shared between Belgium and Bulgaria in Group A with Alison van Uytvanck beating Isabella Shinikova, before David Goffin was seen off by Grigor Dimitrov 6-4 7-5.

Croatia closed the day with a pair of victories against Argentina in Group F as Donna Vekic and Borna Coric defeated Maria Carle and Francisco Cerundolo respectively.

Maria Sakkari sealed victory for top-seeded Greece over Bulgaria in the United Cup with a straight sets win over Viktoriya Tomova.

Team-mates Stefanos Tsitsipas and Despina Papamichail had already won their matches on Thursday, and Sakkari's 6-3 6-2 triumph gave Greece an unassailable 3-0 lead.

Michail Pervolarakis was defeated by Dimitar Kuzmanov in the final singles match between the nations, but Tsitsipas and Sakkari teamed up to earn Greece a 6-4 6-4 success in the doubles encounter to end on a high.

World number 16 Matteo Berrettini helped Italy topple Brazil by overcoming Thiago Monteiro 6-4 7-6 (9-7).

That gave Italy a 2-1 lead, and Lucia Bronzetti finished the job by demolishing Laura Pigossi in straight sets, with Brazil powerless to overturn the deficit despite Berrettini and Camilla Rosatello's defeat in the doubles match.

US Open semi-finalist Frances Tiafoe clinched a win for the United States over the Czech Republic after opponent Tomas Machac retired with an ankle injury with the score at 6-3 2-4.

Petra Kvitova had defeated Jessica Pegula 7-6 (8-6) 6-4 in the third singles match to give Czech Republic hope, but Tiafoe's win settled the contest before Pegula and Taylor Fritz joined up for success in the doubles.

Great Britain were 3-2 victors over Australia despite a pair of defeats on day two in Sydney.

Cameron Norrie's triumph over Nick Kyrgios' replacement Alex De Minaur on day one had helped Great Britain to a 2-0 lead over the hosts, and Harriet Dart prevailed over Maddison Inglis to wrap up the victory.

Dan Evans was then beaten 6-3 7-6 (7-3) by Jason Kubler before Dart and Jonny O'Mara fell to defeat in the doubles, but Great Britain's strong start saw them through.

France and Switzerland completed 5-0 sweeps of Argentina and Kazakhstan respectively, with Caroline Garcia winning both her singles and doubles matches in straight sets while Stan Wawrinka saw off Alexander Bublik 6-3 7-6 (7-3).

Stefanos Tsitsipas opened his United Cup campaign with a comeback victory over Grigor Dimitrov in Perth.

ATP world number four Tsitsipas is one of the headline names in action at the event, which is acting as a warm-up tournament for the Australian Open.

After going a set down to his Bulgarian opponent in his first game of the inaugural tournament, Tsitsipas hit back with a strong second set before holding his nerve in a tense tie-break in the decider, securing a 4-6 6-2 7-6 (7-4) win.

Tsitsipas's team-mate Despina Papamichail continued Greece's strong start, also coming from a set down to beat Isabella Shinikova 3-6 6-4 6-1.

Great Britain opened with a pair of victories, Cameron Norrie and Katie Swan earning straight sets triumphs over their Australian counterparts in Sydney.

Norrie, who was initially set to play Nick Kyrgios prior to the Wimbledon finalist's withdrawal due to an ankle injury, eased to a 6-3 6-3 victory over Alex De Minaur, while Swan defeated Zoe Hives. 

The United States are also taking a 100 per cent record into day two of the tournament, after Taylor Fritz and Madison Keys overcame Jiri Lehecka and Marie Bouzkova respectively, while France pair Arthur Rinderknech and Alize Cornet got off to winning starts against Argentina's Francisco Cerundolo and Maria Lourdes Carle.

In Brisbane, Swiss hope Belinda Bencic secured a 7-6 (7-0) triumph over Yulia Putintseva of Kazakhstan and Beatriz Haddad Maia, the Brazilian world number 15, dispatched Italy's Martina Trevisan 6-2 6-0.

Cameron Norrie is hoping Russian players will be allowed to return to Wimbledon in 2023, saying he wants "the best players in the world to be playing".

Following the Russian invasion of Ukraine earlier this year, Russian players were banned from participating at SW19.

This meant the likes of Daniil Medvedev and Andrey Rublev were not able to play and compete for the third grand slam of the year, which Novak Djokovic ended up winning for the seventh time.

The tournament was stripped of ranking points as a result of the ban on Russians, a decision that was met with much frustration from players.

Medvedev and Rublev finished a respective seventh and eighth in the year-end ATP rankings, and both took part in the ATP Finals in Turin.

Norrie hopes they are able to return to Wimbledon next year, telling reporters: "For me, I want the best players in the world to be playing.

"I felt last year was tough for those guys, especially for Daniil and for Andrey, who have a chance of winning Wimbledon.

"I know how much those guys sacrificed with their careers and their goals are obviously very high to be winning Slams.

"So I really did feel bad for those guys."
