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.

Novak Djokovic said even his vivid imagination could not have dreamt up playing a 10th Australian Open final 15 years after winning his first at Melbourne Park.

The Serbian great has the chance to win a record-equalling 22nd grand slam for a male player after hammering Tommy Paul 7-5 6-1 6-2 – a scoreline that would have been even more commanding had Djokovic not endured a first-set blip from 5-1 up.

Djokovic is already a nine-time singles champion in Melbourne, with his first triumph coming back in 2008, and only Stefanos Tsitsipas stands in his way of a 10th.

"I have a pretty vivid and strong imagination, but even I don't think I imagined it would turn out this way," he said during his on-court interview on Rod Laver Arena.

"Super blessed and grateful, I'm trying to cherish and marvel in every moment. Without my family, without my team these things wouldn't be possible. 

"You're by yourself, all eyes are on you, you take responsibility, you take credit, but you have to give credit where it's due and that's to the team who live with me day by day in good and bad moments. This is as much their success as it is mine."

Only one other male player has won double-digit titles at a single slam, that being Rafael Nadal at the French Open.

Tsitsipas is a player Djokovic has faced in a major final before, defeating the Greek at the 2021 French Open showpiece in a match where he had to come from sets down.

"I won that match, so my recollections are very positive!" Djokovic added to a laugh.

"I came from two sets to love down, I think it was the first time I came down from two sets down in a slam final. It was his first slam final, a really physical and emotional battle. It always is with Stefanos. 

"I respect him a lot, he's one of the most interesting guys off the court, with his interests and hairstyle. But it's all business on Sunday, let the best player win."

Both players were involved in a slog at the start of the second set and when asked about his energy levels, Djokovic joked: "It's great, it's perfect, it's 110 per cent!"

He then added: "Look, of course you're not as fresh as at the beginning of the tournament that's for sure.

"We put a lot of effort in the off season weeks on our fitness, to be in good enough condition to play best-of-five sets."

Sunday's victor will also ascend to the top of the ATP rankings, something Djokovic concedes does add extra spice.

"Of course it does, winning grand slams and being number one are the two biggest peaks you can climb as a tennis player," he said. "Let's see what happens."

Novak Djokovic limped into his 10th Australian Open final with a record-breaking 27th consecutive win in Melbourne against Tommy Paul on Friday.

Djokovic, who has never lost either a semi-final or a final at the first major of the season, came through 7-5 6-1 6-2 to eclipse the Andre Agassi win streak he had tied with a last-eight defeat of Andrey Rublev.

Despite a similar scoreline, however, this was not quite as straightforward as that prior match – particularly in a first set the nine-time champion threatened to throw away.

Djokovic also appeared to be suffering again with the hamstring injury that hampered his preparation for the tournament, but he now needs to come through just one more match, against Stefanos Tsitsipas, to add another title.

The semi ended as it started, with Djokovic in control, yet there was a blip when he looked to be coasting through the opener.

Having just passed up his first set point, Djokovic confronted the umpire when he was not allowed time to take a towel and appeared to lose his focus, allowing Paul to win the next seven points en route to consecutive breaks – the second clinched with a stunning 30-stroke rally.

Finally, with the set level, Djokovic regained some composure and soon enough took a long-awaited second set point before cupping his ear to the Melbourne crowd and being greeted with jeers in return.

It quickly became clear Paul had missed his chance as Djokovic cruised, his primary foe now that troublesome injury.

After stretching out his leg during the first-set collapse, the Serbian appeared in discomfort throughout a dominant second, asking for ice at 5-0 up ahead of Paul's sole hold in the set.

That ailment did not prove enough to derail Djokovic, though, as the third set followed a similar theme in an ultimately commanding semi success.

Data Slam: Djokovic closing on career-best streak

Now the sole owner of the longest Open Era winning streak in the main draw of the men's singles tournament at the Australian Open, Djokovic will match his best run at any grand slam if he beats Tsitsipas, having claimed 28 straight victories at Wimbledon.

Only Roger Federer (40 at the US Open and 40 at Wimbledon) and Bjorn Borg (41 at Wimbledon and 28 at the French Open) have previously had 27-match win sequences at two different majors.

Novak Djokovic needs no extra motivation as he aims to win the Australian Open for a 10th time, as his confidence levels continue to rise.

Djokovic stormed into the semi-finals with a 6-1 6-2 6-4 thrashing of Andrey Rublev on Wednesday.

The Serbian has never lost a semi-final in Melbourne, while he has matched Andre Agassi for the longest Australian Open win streak in the Open Era (26).

Asked if this is as confident he has ever felt at the season's opening major, the 21-time grand slam champion told reporters: "I can't really say that this is as confident that I ever felt because I've had some incredible seasons, years here in Australian Open, some matches that are really unforgettable for me.

"I've been fortunate to really live through a lot of success in Australian Open. But [in the] last two matches, playing against two guys that are really good players, in-form players, to beat them dominantly in three sets is something that sends a message to all my opponents remaining in the draw.

"With this kind of game, of course the confidence level rises. I feel good on the court, better and better as the tournament progresses.

"I've been in this situation so many times in my life, in my career, never lost a semi-final at the Australian Open. Hopefully, that will stay the same."

When it was put to Djokovic that he is even more motivated at the age of 35, Djokovic said: "I don't think that I lack determination.

"I always try to give my best, particularly in grand slams, because at this stage of my career those are the tournaments that count the most, of course.

"You could say that there is something extra this year. You could say because [of] the injury, [and] what happened last year. I just wanted to really do well.

"I have a perfect score in Australian hard courts, in Adelaide and here. I've been playing better and better. I couldn't ask for a better situation to be in at the moment."

Djokovic will face Tommy Paul in the last four, after the American defeated compatriot Ben Shelton. 

Paul has never faced Djokovic, who nevertheless knows what to expect.

"I know how he plays. I never faced him on the court, but he's been around for a few years," said Djokovic.

"I watched him play quite a bit, especially during this tournament. He's been playing probably tennis of his life. Very explosive, very dynamic player. 

"I think he can hit all the spots with the serve. A very complete player. First semi-final for him, so of course he doesn't have much to lose."

Three American men progressed to the quarter-finals in Melbourne for the first time since 2000, and the first time in any grand slam since 2005, and Djokovic believes a strong United States contingent is crucial.

"America for our sport is an extremely important country," Djokovic said. "We have some of the biggest tournaments in the world played there.

"I think it is important that we see successful American men and women. Now you have a list of maybe four or five young players that are knocking on the door of the top level. I think that's great for our sport."

Tommy Paul is into the last four at a grand slam for the first time after overcoming surprise package Ben Shelton in an all-American quarter-final at the Australian Open.

Paul triumphed 7-6 (8-6) 6-3 5-7 6-4 against Shelton at Rod Laver Arena, ending the 20-year-old's surprise run on his first trip outside the United States. 

World number 35 Paul showed his class in longer exchanges between the two big-serving Americans, though Shelton briefly troubled the 25-year-old when he claimed the third set after going a break down.

Having found an immediate break to quell Shelton's momentum, Paul dominated on serve in the fourth set to become the first American man to reach the Australian Open semi-finals since Andy Roddick in 2009.

Having teed up a meeting with either Novak Djokovic or Andrey Rublev, Paul said: "Yesterday when I was doing a couple of interviews, they asked how it felt to be in the quarter-finals, and I was like, 'semi-finals sounds a little better'.

"I'm pumped to be there and really excited for whoever I play. Making it to the second week of a slam is everyone's dream when they start playing tennis. So I can't believe I'm here right now."

Data slam: Paul dominates on serve

Having originally appeared to be on course for a straight-sets triumph, Paul could have lost his way when Shelton claimed the third set, but the 25-year-old was outstanding on serve to see it through.

Paul won all 17 of his first-serve points in the final set, winning 86 per cent throughout the match as his quality told.

For the first time since 2005, the United States will be represented by three players in the men's singles quarter-finals of a grand slam.

Tommy Paul's win over world number 25 Roberto Bautista Agut on Monday ensured his place in the last eight, where he will face compatriot Ben Shelton.

With Sebastian Korda, who defeated Daniil Medvedev in round three, ticking off another top-10 opponent in the form of Hubert Hurkacz, the USA has three male players in the last eight of a major for the first time since the 2005 US Open, when Robby Ginepri, Andre Agassi and James Blake reached the quarters.

It is the first time the USA has had three representatives in the Australian Open quarter-finals since 2000, when Agassi, Pete Sampras and Chris Woodruff made it that far.

While Korda will face Karen Khachanov for a place in the semi-finals, Paul will go head-to-head with Shelton, the world number 89.

Shelton is the lowest-ranked American player to reach a major quarter-final in over 22 years, since Todd Martin at the US Open in 2000, and the lowest-ranked American to get so far in Melbourne since Michael Chang in 1996.

The 20-year-old has already beaten one compatriot, having defeated J.J. Wolff in a five-set thriller in his last match.

Meanwhile, it is the first time since 2006 that no Spanish male players will feature in the quarter-finals at the Australian Open.

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.

Canada will play Italy in the Davis Cup semi-finals after coming from behind to defeat Germany 2-1 in Malaga.

Initially a wildcard for the finals as the highest-ranked losing nation in the qualifiers, the 2019 runners-up are through to the last four for the second time in three years - and fourth time overall.

Felix Auger-Aliassime overcame Oscar Otte in straight sets - condemning him to a fourth straight singles defeat - to set up a doubles decider and cancel out Denis Shapovalov's earlier loss to Jan-Lennard Struff.

Shapovalov and Vasek Pospisil appeared in trouble when they lost the opening set 6-2 against Tim Puetz and Kevin Krawietz, who had won all eight Davis Cup matches when paired together.

But the Canadian duo, who hit a combined 11 aces during the contest, rallied to force a deciding set, which they took 6-3 to inflict a first defeat on their opponents.

Earlier in the day, Italy also came through a deciding doubles match to beat the USA and secure their first semi-final appearance since 2014.

Despite missing the injured Jannik Sinner and Matteo Berrettini, the Italians were appearing in their first quarter-final for six years, and they made a strong start with Lorenzo Sonego hitting 17 aces on the way to defeating Frances Tiafoe 6-3 7-6 (8-6).

Targeting only their fourth semi-final since 2007, 32-time winners USA rallied with Taylor Fritz overcoming Lorenzo Musetti in straight sets to force the first deciding double match of the finals.

There, just one break per set was enough for Simone Bolelli and Fabio Fognini to beat Tommy Paul and Jack Sock 6-3 6-3, and send the 1976 champions through.

Novak Djokovic outclassed Lorenzo Musetti to reach the Paris Masters semi-finals after Carlos Alcaraz retired due to an abdominal injury.

Djokovic moved into the last four of a Masters 1000 event for a staggering 74th time with a commanding 6-0 6-3 victory over Musetti on Friday.

The defending champion will do battle with Stefanos Tsitsipas for a place in the final as he eyes a seventh Paris Masters title.

Sixth seed Djokovic made only 10 unforced errors and broke five times, not allowing his Italian opponent to have a game point until early in the second set.

The 21-time grand slam champion only needed 74 minutes to dispatch the unseeded Musetti, moving two victories away from a fifth title of the season.

Meanwhile, world number one Alcaraz's participation in the ATP Finals next week is in doubt after he was injured in his quarter-final against Holger Rune.

Rune won the first set 6-3 and the Dane was 3-1 up in a second-set tie-break when US Open champion Alcaraz brought the match to a premature end.

As Alcaraz prepares to discover whether he can play in the season-ending tournament in Turin, Rune can look forward to facing Felix Auger-Aliassime in his maiden Masters 1000 semi-final.

Auger-Aliassime beat Rune to take the title in Basel last weekend and the Canadian stretched his winning run to 16 matches by beating Frances Tiafoe 6-1 6-4.

Tsitsipas was the last man to seal his place in the semi-finals, getting the better of Tommy Paul, who beat Rafael Nadal earlier in the week, 6-2 6-4.

Rafael Nadal has turned his focus to the ATP Finals after his shock exit from the Paris Masters, though found it hard to visualise success in Turin.

World number two Nadal crashed out in the second round of the ATP 1000 event on Wednesday, going down 3-6 7-6 (7-4) 6-1 to Tommy Paul.

Nadal, who was contesting his first match since his Laver Cup doubles exhibition with the now-retired Roger Federer, took the opening set and appeared on his way to a comfortable victory when he went up a break in the second.

But Paul broke straight back, going on to win the tie-break before storming home in the decider as Nadal seemed to struggle physically the longer the match dragged on.

Speaking to the media after the loss, Nadal gave credit to his opponent and said he did not deserve to win after blowing his chance.

"It's okay – all the credit to Tommy," he said. "Things happen sometimes.

"I think he played aggressively, a lot of great shots. I had my match in that second set, with a set and break [lead]. 

"I played a terrible game there. I didn't deserve the victory playing that bad in that key moment, no.

"Until that moment, it was okay, a good match for me. Knowing that this is my first match in a while – and this surface especially, you cannot make mistakes with your serve.

"We are always ready to find excuses, but in the end, it's always the same. You play well, you win; you don't, you lose. 

"For moments, putting everything in a pack, I was playing quite well. Then at the right moment, I didn't make the right things. So that's it – he played well, he's having a great year."

Turning his attention to the season finale in Italy, Nadal said he will be there if everything goes to plan.

"Yes, I hope, if nothing happens, I hope to be there," he said. "I'm excited about playing, even if it hasn't been the perfect couple of months for me, of course. 

"But yeah, nothing to lose. After a good year, going there, just trying my best. It's true that for the last five months I didn't spend enough days on the Tour.

"I don't even say competing on a tennis court – I say on the Tour. Practicing with the guys, that's what I need."

His lack of a strong build-up to the tournament has 22-time grand slam champion Nadal admittedly not liking his chances, saying it would be "difficult to imagine" this being the year he is able to win his first ATP Finals title.

"I mean, for me it's difficult to imagine now arriving in good enough shape to win a tournament like this one that I didn't win during my whole tennis career," he said.

"To play against the best players of the world, from the first day you need to be there and the rhythm, conditions, that will not happen. 

"So the only thing I can do is try to be there earlier, have some good practice with the guys and then give my best on the court – and hopefully the level of tennis will be there, and the body too.

"I can't predict much, and I honestly don't think much about what I have to do or what I don't have to do to be really there. 

"I just think about 'be better' – I need to improve a couple of things, and then I need to play sets against the best players, to feel myself again, competitive against everyone.

"That's it – I'm gonna try to make that happen – and if not, you know what, there's going to be next year, and I'm going to try to have the best season possible to start strong."

Dominic Thiem produced a dominant display to cruise past Joao Sousa in the duo's first-round clash at the Gijon Open, only dropping two games for just the second time in his career.

The 2020 US Open winner did not face a single break point in his one-sided 6-2 6-0 victory on Monday, reaching the last 16 after 62 minutes.

It is just the second time in the Austrian's career he has lost as few as two games in a completed ATP-level match, having previously done so against Jaroslav Pospisil in 2013 (in a 6-1 6-1 win).

"Especially with the forehand, it was really good for basically the first time [since my injury]," Thiem said afterwards. "I'm very happy about it. This way is right, the direction is right."

Meanwhile, Argentina's Sebastian Baez was forced to retire when a set down to France's Constant Lestienne, and fifth seed Tommy Paul eased past 16-year-old home hope Martin Landaluce in straight sets.

Only one seed was in action at the Firenze Open on Monday, with Aslan Karatsev advancing courtesy of a walkover following an injury to Tallon Griekspoor. 

Nick Kyrgios' red-hot form has been halted after going down in three sets to eighth seed Hubert Hurkacz in the quarter-finals of the Canadian Open on Friday.

Hurkacz ran away with victory, triumphing 7-6 (7-4) 6-7 (5-7) 6-1 in one hour and 46 minutes in Montreal.

Wimbledon finalist Kyrgios had come into the encounter fresh from winning 15 of his past 16 matches, including lifting the title at last week's Washington Open. Kyrgios' run had fueled expectations around him at the upcoming US Open.

"Nick has been playing some incredible tennis throughout the past weeks, so it is a pleasure playing against him," Hurkacz said post-match in his on-court interview.

"I started really well. Nick was maybe a little bit injured, which might have hurt his serve. With both of us serving so well, that few per cent can make the difference."

Kyrgios was quick on serve but the 25-year-old Pole eventually ground him down, prevailing in the third set aided by an early break.

That break came after Kyrgios gave up two double faults, leading to the Australian to complain to the umpire about his opponent's mid-match break for a change of clothes.

The Australian was unable to break Hurkacz's serve throughout the match, with the Pole edging the aces count 20-19, while he was also superior on return. Kyrgios had more winners (55-47), but more unforced errors (24-13).

Hurkacz, who will face fourth seed Casper Ruud in the semi-finals, is the only former Masters 1000 champion left in the draw.

Ruud cruised into the last four with a 6-1 6-2 victory over hometown hero Felix Auger-Aliassime who was brushed aside in one hour and 14 minutes.

The Norwegian's win marks his third ATP Masters 1000 semi-final of the season, with the Canadian plagued by 21 unforced errors compared to Ruud's eight.

Unseeded Briton Daniel Evans fought back from a lopsided opening set to knock off Tommy Paul 1-6 6-3 6-4.

Evans will face Spaniard Pablo Carreno Busta after he defeated Jack Draper 7-6 (7-4) 6-1 in just under two hours.

Second seed Hubert Hurkacz was a shock second-round casualty from the Citi Open on Wednesday after a straight-sets defeat to Emil Ruusuvuori.

World number 46 Ruusuvuori triumphed 6-4 7-6 (7-3) in one hour and 43 minutes to book a quarter-final spot.

Hurkacz, who is ranked 11th in the world and reached last year's Wimbledon semi-finals, fought hard but failed to capitalise on four break points throughout the match.

"He had an early break point, but then I was able to keep that service game and give myself a chance to break him and I was able to use it and then just try to keep my own serve," Ruusuvuori said.

"I just tried to hang in there and tried to stay as tough as [I] can."

Wimbledon runner-up Nick Kyrgios defeated 14th seed Tommy Paul 6-3 6-4 in one hour and 25 minutes.

The Australian hit 29-21 winners, with the majority coming from his serve and forehand, sending down 15 aces, winning 84 per cent on his first serve.

Kyrgios, who broke Paul in his opening service game, converted three of four break points for the match, while the American failed to capitalise on any of his four.

Sixth seed Denis Shapovalov was bundled out in the second round by American wildcard J.J. Wolf 6-2 6-7 (5-7) 6-3 in a major upset.

Third seed Taylor Fritz avoided an early exit with a 6-4 6-4 win over Australian Alexei Popyrin in one hour and 11 minutes, while fourth seed Reilly Opelka came from a set down to defeat Denis Kudla 6-7 (6-8) 6-4 6-4 in just over two hours. Opelka sent down 28 aces across the match.

Fifth seed Grigor Dimitrov got past Adrian Mannarino 6-1 3-6 7-5 and ninth seed Holger Rune brushed off Benoit Paire 6-3 6-2.

Francis Tiafoe defeated Christopher Eubanks 6-3 7-6 (7-2), while 13th seed Maxime Cressy fought back from an early deficit to get past Jack Sock 4-6 6-4 6-0 to set up a third-round clash with top seed Andrey Rublev.

There were defeats for 11th seed Alex de Minaur to Yoshihito Nishioka 3-6 7-6 (8-6) 6-2, 12th seed Sebastian Baez against Sebastian Korda 6-1 6-4 and 15th seed Aslan Karatsev against Andy Murray's first-round conqueror Mikael Ymer 6-4 3-6 6-4.

At the Los Cabos Open in Mexico, second seed Felix Auger-Aliassime had no troubles against local Juan Alejandro Hernandez Serrano, winning 6-3 7-5.

American sixth seed Brandon Nakashima also progressed into the quarter-finals with a 6-3 6-3 win over Max Purcell, while Miomir Kecmanovic beat Jordan Thompson 6-4 6-2.

It was smooth sailing for the seeded competitors in action on Wednesday at the Atlanta Open, with Tommy Paul, Frances Tiafoe and Brandon Nakashima all advancing in straight sets.

Fifth seed Paul started the day off with a straightforward 6-3 6-3 win against South Korea's Kwon Soon-woo thanks to a clear advantage with his serving. He won 73 per cent (36-of-49) of his points on serve, while Kwon could only muster 53 per cent (34-of-64).

Paul will meet Belarus' Ilya Ivashka in the quarter-finals after he successfully navigated the challenge of America's Steve Johnson 4-6 6-2 6-4 after Johnson was a late injury replacement for top overall seed Reilly Opelka.

Ivashka is now 6-3 in his nine matches since the French Open, with his only losses against top-five talents Stefano Tsitsipas and twice against Daniil Medvedev.

Fourth seed Tiafoe was impressive against Japan's Taro Daniel, creating eight total break point opportunities, and capitalising on three. 

Tiafoe will play Nakashima in the quarter-finals, with the American surviving a tough first set tiebreaker to eventually defeat Australia's John Millman 7-6 (10-8) 6-4.

In a closely contested match, Nakashima avoided getting into many sticky situations, saving the only break point he faced.
