Germany booked their place in the Davis Cup semi-finals after wrapping up a 2-0 victory over Canada in Malaga.

Daniel Altmaier and Jan-Lennard Struff were both victorious over Gabriel Diallo and Denis Shapovalov respectively, to set up a last-four clash with the Netherlands.

Germany were beaten 2-1 by Canada when the nations met at this stage of the 2022 Davis Cup, but they drew first blood when Altmaier came through a hard-fought clash with Diallo 7-6 (7-5) 6-4.

It looked like the tie would go to a doubles decider when former Wimbledon semi-finalist Shapovalov took the opening set against Struff.

But the world number 43 bounced back to prevail 4-6 7-5 7-6 (7-5) after two hours and seven minutes.

"Denis was playing amazingly, coming out firing," Struff said. "It was a very tough match. He was serving so well. It was tough to return. The court is very fast. An incredible match. I'm just happy to get over the line at the end."

On Friday's semi-final with the Dutch, he added: "It's a big step for us to go from the quarters to the semis. For sure, we want to win and go to the final now.

"Netherlands played an amazing match yesterday, beating Spain here in front of a home crowd. We expect a very tough opponent."

Data Debrief: Germany through as errors cost Canada

The two tie-breaks proved pivotal as the Germans secured only their second Davis Cup semi-final appearance since 2008 (also reaching that stage in 2021).

Though both sets were tight during the first match, Diallo hit 40 unforced errors to Altmaier's 17, and was 6-1 for double faults.

Similarly, in the second rubber, though Shapovalov was 27-8 for aces, 13 double faults to just four from Struff proved costly.

Altmaier and Struff's reward is a first meeting with the Netherlands since the 2001 quarter-finals, which the Dutch won 4-1.

Canada beat Great Britain to ensure their progress to the Davis Cup Final 8 on Sunday, with Denis Shapovalov beating Dan Evans and Felix Auger Aliassime overcoming Jack Draper.

Canada needed just one point from their final group-stage tie, and Shapovalov did the honours at the first time of asking by beating Evans 6-0 7-5.

Shapovalov won 100% of first-serve points as he dominated an opening set that lasted just 27 minutes, and though Evans came back into the encounter in the second set, a break in the final game sealed the deal for Shapovalov.

With Canada's progress secured, Auger Aliassime then added some gloss by overcoming US Open semi-finalist Draper 7-6 (10-8) 7-5 in a fiercely contested affair.

British pair Neal Skupski and Henry Patten beat Gabriel Diallo and Alexis Galarneau 7-6 (7-4) 6-4 in the doubles, but it was of little consequence with their elimination already certain.

Argentina joined Canada in qualifying from Group D with a sweep of Finland, while Italy finished top of Group A in Bologna, thanks to the efforts of Flavio Cobolli.

He beat Tallon Griekspoor 7-6 (7-4) 4-6 6-3 as the Netherlands were forced to settle for second, after Matteo Berrettini had put the defending champions in the driving seat with a 3-6 6-4 6-4 win against Botic van de Zandschulp.

World number one Jannik Sinner was present to support Berrettini, embracing him after he capped his fightback by converting match point. 

Australia and Spain had already sealed qualification from Group B prior to Sunday's matches, while the United States and Germany had clinched their progress from Group C.

The Davis Cup Final 8 will take place in Malaga between November 19 and November 24, with Italy hoping to become the first team to defend the title since the Czech Republic in 2013.

Felix Auger-Aliassime and Denis Shapovalov moved Canada to the brink of qualification in the Davis Cup Finals group stage, comfortably dispatching Finland in Manchester.

Shapovalov needed just an hour and 13 minutes to beat Eero Vasa 7-6 (7-2) 6-2, backing up his win against Argentine Francisco Cerundolo on Tuesday. 

The Canadian served five aces to his opponents' three, producing three love games in the final set to get his nation off to a flying start. 

Auger-Aliassime followed up Shapovalov's victory with another straight sets win, this time over Otto Virtanen, emerging a 6-2 6-3 victor. 

The world number 21 was dominant on serve throughout his 73-minute triumph, saving all three break points he faced and winning 86% of his first-serve points. 

Auger-Aliassime and Shapovalov then prevailed in the doubles against Harri Heliovaara and Virtanen in another straight sets win, putting them top of Group D without dropping a set against their opponents.

Felix Auger Aliassime and Denis Shapovalov helped Canada make a winning start to their Davis Cup Finals group-stage campaign, overcoming Argentina in Manchester.

Former Wimbledon semi-finalist Shapovalov got Canada off to a flier in the opening singles match of the Group D encounter, beating Francisco Cerundolo 7-5 6-3 in one hour and 37 minutes.

Cerundolo committed 51 unforced errors in a disjointed display, giving up back-to-back breaks early in the second set as the match slipped away from him after a competitive opener.

Not to be outdone, Auger Aliassime followed up Shapovalov's victory by beating Sebastian Baez 6-3 6-3, keeping his opponent under fierce pressure throughout and converting seven of the 12 break points he forced.

Doubles specialists Maximo Gonzalez and Andres Molteni then beat Shapovalov and Vasek Pospisil in three sets, but that was not enough to deny Canada victory.

Great Britain and Finland are the other two teams in Group D, with Jack Draper leading the hosts' bid to reach the knockout stages in Malaga later this year.

World number one Jannik Sinner has been "worn down physically and mentally" by an investigation into his positive tests for a banned substance, says his coach Darren Cahill.

In March, Australian Open champion Sinner twice tested positive for clostebol – a banned substance that can be used to build muscle mass.

However, an independent tribunal last week found he was inadvertently given the substance in an over-the-counter spray by his physiotherapist Giacomo Naldi.

Sinner has won ATP-level titles at Halle and Cincinnati since the positive tests, but he was eliminated from the French Open at the semi-final stage and only reached the last eight at Wimbledon.

He then missed the Paris Olympic Games after being diagnosed with tonsillitis, and Cahill feels it was no coincidence that he failed to hit top form while the probe was ongoing.

"I guess if you are not a Jannik fan, you may not see too much difference in what he has been doing the last few months because he has still been playing quite well," Cahill told ESPN.

"But if you are a Jannik fan, you would have seen a big change in his body language, his physicality on the court, his excitement to be on the court.

"He's struggled and I think it's worn him down physically and mentally. He got tonsillitis, which is the reason why he missed the Olympics."

Some have been critical of the decision to clear Sinner of any wrongdoing, with 2022 Wimbledon runner-up Nick Kyrgios particularly vocal in his reaction.

Kyrgios wrote on X it was "ridiculous" that Sinner had escaped a ban, saying the Italian deserved to be hit with a two-year suspension.

Former Wimbledon semi-finalist Denis Shapovalov also suggested the decision was at odds with other players receiving bans over similar incidents.

Cahill, however, is of the belief Sinner would never intentionally take a banned substance, adding: "I just want to stress that he's maybe the most professional young man that I have ever had the chance to work with. 

"He would never ever intentionally do anything, and he's in a situation that is incredibly unfortunate."

Novak Djokovic celebrated his 37th birthday by breezing into the Geneva Open quarter-finals after his comfortable straight-sets victory against Yannick Hanfmann.

The world number one made light work of Hanfmann, who defeated Andy Murray the day before, after a 6-3 6-3 victory in Switzerland on Wednesday.

Serbia's Djokovic saved nine of the 10 break points faced and won six straight games in the second set for a routine victory, responding emphatically after going 3-0 down.

The winner of a last-16 meeting between Denis Shapovalov and Tallon Griekspoor awaits in the last eight for Djokovic, who triumphed with little trouble on his 37th birthday.

Data Debrief: Age will not stop Djokovic

Having watched rivals Roger Federer and Rafael Nadal struggle for fitness in the latter stages of their career, Djokovic is showing no signs of slowing down before the French Open starts later this month.

Djokovic will be aiming to become the second player in the Open Era to secure a Grand Slam Singles title after turning 37, along with Ken Rosewall at the Australian Open 1972.

Great Britain will play Canada, Finland and Argentina in the group stage of the Davis Cup Finals in Manchester in September.

Leon Smith’s side will hope for a less nail-biting conclusion than in the same city last year, when Dan Evans and Neal Skupski saved match points to beat France in the deciding match in front of a jubilant record crowd, and the draw appears to have been relatively kind.

Canada, led by Felix Auger-Aliassime and Denis Shapovalov, were champions in 2022 but lack strength in depth.

Finland were last year’s surprise package, making it through to the semi-finals for the first time, while Argentina boast three top-30 players, but indoor hard courts should favour Britain.

The ties will take place at the AO Arena from September 10 to 15, with the top two teams progressing to November’s Final Eight event.

Having beaten France, Australia and Switzerland last year, Britain fell at the first hurdle in Malaga, losing out to Novak Djokovic’s Serbia.

Defending champions Italy will host a group in Bologna also featuring the Netherlands, Belgium and Brazil, while Australia, Czech Republic, France and Spain will contest a heavyweight Group B in Valencia.

The final group, containing Germany, USA, Slovakia and Chile, will take place in the Chinese city of Zhuhai.

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.

Stefanos Tsitsipas breezed into the third round of the Barcelona Open with a straight-sets win over Pedro Cachin on Wednesday.   Tsitsipas took 79 minutes to see off Argentine Pedro Cachin 6-4 6-2 on Pista Rafa Nadal.   The second seed from Greece did not face a break point and won all three that he fashioned to set up a meeting with Canadian Denis Shapovalov, who got the better of Jozef Kovalik 6-4, 6-3.   Jannik Sinner, the fourth seed from Italy, eased to a 6-2 6-4 win over Diego Schwartzman at the Real Club de Tennis Barcelona-1899.   Cameron Norrie and Lorenzo Musetti will do battle in round three after defeating Pavel Kotov and Jason Kubler respectively in straight sets.   Karen Khachanov beat Nicolas Jarry 6-4 6-4, while Grigor Dimitrov, Dan Evans, Alex de Minaur, Yoshihito Nishioka and Francisco Cerundolo also celebrated midweek wins.   Rain hit the schedule hard at the BMW Open, where Aslan Karatsev was leading Daniel Altmaie 3-0 in the third set when play was suspended in the only singles action of the day.  

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.

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.

Denis Shapovalov suffered defeat at the hands of China's fast-rising Wu Yibing at the Dallas Open.

Wu landed a 7-6 (7-1) 6-4 win against the Canadian Davis Cup winner and former top-10 player in their second-round contest.

World number 97 Wu, who this week became China's second player to reach the ATP top 100, has surged from 1,869th on the ranking list last April and believes he can crack the top 30 by the end of the year.

Speaking after getting the better of Shapovalov, who stands at 27th in the rankings, Wu said: "I've been playing great tennis the past few months. Hopefully I can keep playing good."

Frances Tiafoe cruised into the quarter-finals with a 6-1 6-3 win over fellow American Mackenzie McDonald.

Second seed Tiafoe was playing for the first time since his third-round elimination to Karen Khachanov at the Australian Open last month.

He faced just one break point in the entire match and needed just 59 minutes to deal with the world number 59.

J.J. Wolf, seeded sixth, will face Tiafoe in the last eight after he saw off Romania's Radu Albot in a 6-3 7-6 (7-5) win.

At the Cordoba Open, fifth seed Pedro Cachin was the biggest casualty on Wednesday as he was beaten 6-3 6-4 by Bolivian qualifier Hugo Dellien.

Seventh seed Pedro Martinez was also ousted in the first round, while Bernabe Zapata Miralles was sent packing by Tomas Barrios Vera in the last 16, losing 5-7 6-4 6-3.

Fourth seed Sebastian Baez had no such issues with Italy's Luciano Darderi, however, reaching the quarter-finals as a 6-3 6-4 winner.

Novak Djokovic took just an hour and 15 minutes to win his first singles match in Australia since 2021, beating Constant Lestienne 6-3 6-2 at the Adelaide International on Tuesday.

Djokovic – who saw a three-year visa ban lifted in November – played with Vasek Pospisil in the doubles on Monday, but this was his first singles outing in the country since his vaccine-related absence from last year's Australian Open.

"For the first match [of the season] I can't complain," Djokovic said. "I played very well. I thought the first six games were very competitive and I have never faced him before.

"But once I made that break at 3-2 in the first set I thought I stepped it up and played really good tennis for the rest of the match."

Elsewhere in Adelaide, third seed Daniil Medvedev advanced after Lorenzo Sonego retired hurt with the Russian leading by a set, while sixth seed Jannik Sinner eased past Kyle Edmund 6-3 6-2.

Seventh seed Denis Shapovalov is also through after coming from a set down to beat Rinky Hijikata, but fourth seed Andrey Rublev is out after losing to Roberto Bautista Agut in three sets.

There were also wins for Maximilian Marterer against Elias Ymer and Pedro Martinez against Ramkumar Ramanathan.

Felix Auger-Aliassime and Denis Shapovalov steered Canada to Davis Cup glory in Sunday's final against Australia in Malaga, earning the country their first title in the competition.

Canada were runners-up three years ago in Madrid, when a 19-year-old Auger-Aliassime and 20-year-old Shapovalov lost their respective singles clashes with Roberto Bautista Agut and Rafael Nadal.

Three years older and three years wiser, this time the Canadians dominated the trophy match at the expense of 28-time champions Australia.

Shapovalov got Canada off to a flying start by crushing Thanasi Kokkinakis 6-2 6-4, setting up the chance for Auger-Aliassime to clinch victory without the need for the contest to go down to a doubles decider.

World number six Auger-Aliassime made no mistake as he fended off Alex de Minaur 6-3 6-4, adding Davis Cup glory to the four singles titles he has gathered this year.

Auger-Aliassime saved three break points in the sixth game of the second set, from 0-40, when a trailing De Minaur was looking to hit back. He then sealed Canada's victory minutes later with a forehand into the corner that his opponent could only return out of court, before being mobbed by team-mates.

Each of Auger-Aliassime's 2022 titles came at indoor hard court events, and he has thrived again in those conditions this week, winning all three of his singles rubbers and a doubles tussle on Saturday against Italy alongside the experienced Vasek Pospisil.

The Canadian pair got the job done just minutes before kick-off time in their country's World Cup game against Croatia.

"The emotions are hard to describe," said Auger-Aliassime. "All of us here, we've dreamt of this moment.

"These guys around me, except Vasek, he's a little bit older than me, we grew up together from the ages of seven, eight years old in Canada dreaming about being on this stage, winning these types of matches, winning a Davis Cup.

"It's really a dream come true, for me personally and I think for all the team. It was a great moment for myself and the country."
