Andy Murray raised doubts over his future after losing in the third round at Wimbledon, leaving the grand slam with one question: "Is it worth it?".

Murray's Wimbledon journey came to an end on Friday following the former world number one's 6-4 6-2 6-2 loss to 10th seed Denis Shapovalov on Centre Court.

Making his first appearance in the main draw since he was the defending champion at Wimbledon in 2017, Murray's career has been devastated by injuries.

Murray underwent hip resurfacing in 2019 but the three-time grand slam champion has continued to be plagued by fitness problems.

After suffering his earliest Wimbledon exit since 2005, Murray was in a downbeat mood as he was left to ponder his next move.

"It was great playing in front of the crowds again," the 34-year-old said. "I got amazing support here. I'm very thankful for that. Something I have missed. It kind of reminds you why you do all of the work and everything.

"But then, on the flip side of that, the positive part is getting through the matches and feeling OK physically and not getting injured.

"That's good but then there is a part of me that feels a bit like I have put in so much work the last three months and ultimately didn't play how I would want and expect, and it’s like, is it worth it?

"Is all of that training and everything that you're doing in the gym, unless you're able to practise and improve your game and get matches and get a run of tournaments, is it worth all of the work that you're doing?

"There is part of me that feels like, yes, it is, because I had great memories and stuff from this event and playing in some brilliant atmospheres. But I finished the match tonight and I'm saying to my team, 'I'm just not happy with how I played'.

"So, unless me and my team can find a way of keeping me on the court for a consistent period of time and allow me to practise the way that I need to to compete with these guys, that's when the discussions about what I do next will come in.

"Because I have genuinely put a lot into this to get to this point, but I'm not being able to practise and prepare how I need to to perform how I would like at these events.

"I’m not expecting and saying I would beat Denis Shapovalov. He's a brilliant player. But I feel like I can do a lot better than what I did this evening."

Andy Murray's Wimbledon adventure is over – for this year at least – after Denis Shapovalov put an end to his challenge in a one-sided Centre Court clash.

The doughty two-time former champion insists retirement is not at the forefront of his mind, but a 6-4 6-2 6-2 loss to 10th seed Shapovalov was a fresh reminder of his current place in the tennis pecking order.

After hip resurfacing surgery gave Murray another shot at the career that at one stage looked all but over, it was a Wimbledon return which was high on his list of priorities.

This was Murray's first appearance in the singles since 2017, the year he was last defending champion.

Earlier this year the former world number one spoke of a belief that he could win the tournament for a third time, but he will be 35 by the time next year's championships come around and many have doubts about whether he will still be playing. He came into this fortnight at 118th in the rankings.

Not even the closure of the Centre Court roof could save Murray this time. That had been the spur, coincidentally or not, for his two previous late-night matches to swing around in the Scot's favour, as he saw off Nikoloz Basilashvili and then the unheralded German Oscar Otte to reach this last-32 stage.

Murray and Shapovalov went off after the second set of this contest, as evening turned to night in south-west London and the lights came on, but Murray did not return with super-human strengths this time, and his opponent raced to victory.

Shapovalov told Murray at the net that the Scot was his hero, and spoke eloquently about his appreciation of his comeback, and perhaps Murray would have quietly admired the Canadian's skill in moving in for the kill.

This match had been all one way for much of the first set too, but then Murray found a spark and pulled back from 5-1 adrift to 5-4, the crowd beginning to believe it could be his day again.

Murray believed too, of course, but this match proved a step too far for the champion of 2013 and 2016. There were flickers of Murray at his best, and he will represent Great Britain at the upcoming Olympics, where he is a two-time defending champion, but Murray's days of being a grand slam contender are, on the balance of probabilities, pretty much over.

His career has been a spectacular affair, and there was a familiar ovation as he departed Centre Court.

Shapovalov had rammed down an ace on match point, clinical in his despatching of the crowd's favourite.

Speaking at the end of the match, Shapovalov said in an on-court interview: "This is a dream come true for me.

"I've put countless years of hard work into every practice so that one day maybe I could play on Centre Court – to play against a legend like Andy today, to play a match like this. First of all, huge shout-outs to him. What he is doing nobody has ever done. He's truly an inspiration to many people, including me.

"I just told him at the net that he's my hero. Achievements aside, what he's been able to do in the sport with an injury like this and to play the tennis he's playing and moving the way he's moving.

"In his second match it was like vintage Andy and it was just so much fun to see as a fan. I was really excited and the first set today was super, super intense.

"It's incredible what he's done to make it to the third round like this and he's just starting back up so it's going to be amazing to see what he can do."

Matteo Berrettini continued his impressive charge at the Queen's Club Championships as he booked a place in the final against Cameron Norrie.

Top seed Berrettini, ranked nine in the world, has not dropped a set all week.

His impressive run has seen him defeat home hopes Andy Murray and Dan Evans, with one more Briton in the shape of Norrie left to see off in his bid for glory.

Berrettini ensured he will be in the final by claiming a 6-4 6-4 triumph over fourth seed Alex de Minaur in the semi-final on Saturday.

The Italian dropped just four of his 36 points on first-serve and sent down eight aces, with De Minaur only able to force one break point in the entire contest, which he did not take.

"[Making the final] was the goal of the week and now I have one more step," said Berrettini.

"It is a great achievement, especially for the history of this tournament. I am really happy because to beat Alex, I had to play my best tennis."

Berrettini has four tour titles to his name, though this would be his first at ATP 500 level or above.

Victory would also represent the biggest win of Norrie's career – he has lost each of his three previous finals, all at ATP 250 level.

Norrie impressively eliminated Denis Shapovalov to reach the showpiece, beating the Canadian 7-5 6-3.

Shapovalov had earlier finished off a 6-3 6-4 quarter-final win over Frances Tiafoe, a match that could not be completed on Friday due to fading light.

But the second seed could not muster up another victory against a fresher Norrie.

At the Halle Open, Andrey Rublev reached his eighth final since the start of 2020, though his first on a grass court.

Rublev dropped his first set of the week but ultimately prevailed with a 6-1 3-6 6-3 semi-final victory over Nikoloz Basilashvili.

The Russian has won his last four finals at ATP 500 level and will seek a fifth on Sunday.

"It's my first final on grass and in Halle," he said. "I think I can play on every surface and I will try my best again.

"I had good opportunities to break Basilashvili in the second set, some quite easy forehands and I stressed a little showing my emotions. 

"I then came back and stayed calm, until the last game. But I won."

Rublev will take on unseeded Ugo Humbert, who held his nerve to edge a thriller against Felix Auger-Aliassime, winning 6-4 3-6 7-6 (7-5).

Humbert beat Alexander Zverev earlier in the week and has had to win a deciding set in all four rounds, while the beaten Auger-Aliassime had previously seen off Roger Federer as part of a dramatic event.

Frenchman Humbert won each of his first two career finals, which both took place last year in ATP 250 events.

Top seed Matteo Berrettini has his sights set on the Queen's Club Championships title after beating Dan Evans in the quarter-finals.

After a delay of more than four hours because of rain in London, Berrettini overcame Evans 7-6 (7-5) 6-3 to reach his third ATP grass-court semi-final.

The Italian hit 13 aces and won 81 per cent of his first-serve points against Evans to set up a last-four clash with Alex de Minaur. 

Berrettini improved his win-loss record to 24-6 for the season and laid out his ambition to walk away from the tournament with the trophy.

"I didn't serve that well, but I was returning well and I just played better in the last few points of the tie-break," he said.

"After that, I felt more confident. The conditions were really tough, windy and cold, so I took time to adapt a little bit. I am pretty happy with my performance.

"The court condition was really good. I expected slippery conditions, but it was like yesterday.

"I came here to win the tournament, that is my goal. Now I am two steps away. I am happy with the way I am playing, and my mental attitude is really good."

Up next for Berrettini is Australian De Minaur, who came from behind to defeat Marin Cilic 3-6 6-3 6-4.

The 22-year-old won 73 per cent (22/30) of his second-serve points and saved six of the seven break points he faced as he moved to 16-12 for the season.

In the battle of the British players, Cameron Norrie beat Jack Draper 6-3 6-3, while Denis Shapovalov was leading Frances Tiafoe 6-3 when their match was suspended due to fading light. They will resume on Saturday.

At the Halle Open, Andrey Rublev reached his sixth ATP Tour semi-final of the year thanks to a 7-6 (7-4) 6-2 win over 2011 champion Philipp Kohlschreiber.

"I am happy with my performance to reach the semi-finals for the first time," Rublev said. "The first set was really tough. He was 3-0 up in the tie-break and I came back, which was the key.

"After the first set, I think he mentally went down and I was pumped up. I hit a couple of good returns in the first game of the second set."

Russian Rublev will face Nikoloz Basilashvili in the last four after the Georgian defeated Lloyd Harris 6-4 7-6 (7-5). 

In the day's other quarter-finals, Felix Auger-Aliassime beat Marcos Giron 6-3 6-2 and Ugo Humbert overcame Sebastian Korda 6-2 6-7 (5-7) 6-4.

Top seed Matteo Berrettini beat Andy Murray to reach the quarter-finals at Queen's Club and Ugo Humbert upset Alexander Zverev at the Halle Open on Thursday.

Murray, a five-time champion at Queen's, was beaten 6-3 6-3 by Italian Berrettini as the three-time grand slam champion struggled a day on from being given a Wimbledon wildcard.

The former world number one beat Benoit Paire in his first ATP Tour singles match since March on Tuesday, but the 34-year-old revealed he is still being troubled by a groin injury after his loss to Berrettini and knows he must raise his game.

Murray said: "I actually felt my movement was actually quite good for both of the matches. My tennis today was not very good. That's the thing that I'll need to improve the most.

"Then there is still a slight niggle in the groin, so [I have] to try to get rid of that discomfort between now and Wimbledon. I need to be playing points, basically. I played two sets in preparation for this event.

"I do feel like I genuinely have been hitting the ball well in practice, but then like today when you're under a bit more pressure and stuff and you're having to make very split-second decisions when you're on the court, if the guy is serving 140 miles an hour, like, it's difficult to prepare for that."

Dan Evans made history earlier in the day, getting the better of Adrian Mannarino 6-4 7-6 (9-7).

With Jack Draper and Cameron Norrie having already progressed, Evans' win ensured there will be three Britons in the singles quarter-finals for the first time in the Open Era.

Feliciano Lopez will not retain his title in London after the Spaniard went down 6-2 6-3 to second seed Denis Shapovalov. Spanish veteran Lopez won in 2019, with last year's tournament cancelled due to the pandemic.

There will be no glory on home soil in Halle for German Zverev, who was taken out 7-6 (7-4) 3-6 6-3 by unseeded Frenchman Humbert.

Humbert has now beaten a top-10 player on every surface, with Zverev serving 20 aces but bowing out after his 22-year-old opponent claimed the only break of the final set.

Sebastian Korda battled past Kei Nishikori 2-6 6-3 7-5 in Halle, while Lloyd Harris also moved into the last eight at Lukas Lacko's expense.

Top seed Denis Shapovalov failed to reach the semi-finals of the Stuttgart Open as his busy Friday ended with defeat to Marin Cilic.

Shapovalov had earlier completed a rain-delayed match with Feliciano Lopez, winning in three sets.

However, the Canadian was beaten in two tight sets by former US Open champion Cilic, who prevailed 7-5 7-6 (7-3).

"I felt I was applying a little more pressure during that first set and I capitalised on the couple of break points, which was definitely big, just to give me a bit of extra momentum," Cilic said.

"I also had the two match points at the end of the second set, didn't convert them, but played a really good tie-break. You always have to expect tough battles against top guys like Denis and it was like that today."

Cilic will face Jurij Rodionov after the Austrian came from behind to stun fourth seed Alex de Minaur, a player ranked 120 places above him, 3-6 6-3 7-6 (7-4).

Shapovalov's Canadian compatriot Felix Auger Aliassime remains in the draw, though, going through to the last four with a 7-6 (7-5) 7-6 (10-8) win over Ugo Humbert in which he hit 17 aces.

Auger Aliassime, the lone seed left in the tournament, is hoping to repeat his run to the final in 2019. Standing in his way will be the sizeable figure of Sam Querrey, who ended wild card Dominic Stephan Stricker's superb tournament.

Teenager Stricker had match point at 5-4 in the second set but Querrey fought back to progress 6-7 (4-7) 7-6 (7-4) 6-3. Querrey won all 14 of his first-serve points in the final set.

Teenager Dominic Stephan Stricker produced the shock of the day at the Stuttgart Open as he knocked out second seed Hubert Hurkacz in the round of 16.

The 18-year-old wildcard, ranked 335 in the world, claimed a straight sets victory courtesy of tie-breaks, as had been the case in his previous outing against Radu Albot.

And his reward for a 7-6 (7-5) 7-6 (7-5) win over a man placed 315 places higher than him in the men's rankings is a quarter-final tie against Sam Querrey.

The American sealed his passage into the last eight by beating qualifier James Duckworth 6-4 7-6 (9-7) on Thursday.

Top seed Denis Shapovalov's place in the next round remains in doubt going into Friday after the Canadians clash with Feliciano Lopez was cut short by rain with both men having taken a set.

The winner of that final set will face former world number three Marin Cilic, who comfortably beat Nikoloz Basilashvili 6-3 6-2.

Another Canadian also remains in the draw in the form of third-seeded Felix Auger-Aliassime after his 6-3 7-6 (7-4) win over Lloyd Harris.

There, he will face sixth seed Ugo Humbert after his straight sets win over wildcard entry Yannick Hanfmann.

The quarter-final line-up is completed by fourth seed Alex de Minaur, who beat compatriot Jordan Thompson, and Jurij Rodionov, whose progress was aided by Peter Gojowczyk's first-set retirement.

Rising star Casper Ruud continued his impressive 2021 with a straight-sets win over Denis Shapovalov in the Geneva Open final to win his second career title.

The world number 21 prevailed 7-6 (8-6) 6-4 in the first top-level meeting between the two players to add to the Argentina Open crown won – also on clay – in February 2020.

Ruud did not face a single break point in the match, which lasted an hour and 40 minutes, and needed only one break conversion himself to see off second seed Shapovalov.

"It's tough to find all the words," said Ruud, who has a 15-4 record on clay this year. 

"It was such an amazing week here in Geneva. I was always looking forward to coming to this tournament.

"I watched it on TV for many years when I was younger and it always seemed like a nice place, so I guess I know why I wanted to come here.

"It's been going well and this week has been unbelievable for me."

Looking to lay down a marker ahead of the upcoming French Open, where he reached the third round last year, third seed Ruud took little time to get going against Shapovalov.

However, the first set went the way of the serve to set up a tie-break, which the Norwegian eventually took with his fifth set point after Shapovalov won four points in a row.

Shapovalov was competing in his third tour-level final after winning the Stockholm Open and losing in the Paris Masters final in 2019, but he struggled to break his opponent.

Ruud earned a break in the fifth game of the second set and saw the job through to keep his momentum going ahead of the second grand slam of the year.

Asked about his aims for Roland Garros, Ruud said: "Well, it's the toughest clay court tournament of the year.

"This season I am playing well on the clay and I'm looking forward to Paris. I hope I can make the second week, that's all I can say.

"If I'm in the second week I will be very happy of course."

Stefanos Tsitsipas insists it must be purely business when he tackles Italian teenager and fellow tennis artisan Lorenzo Musetti in the Lyon Open semi-finals.

Ahead of a tilt at the French Open, for which he is among the favourites, world number five Tsitsipas has been tuning up his game at this week's ATP 250 tournament.

The Greek star was sharp in posting a 6-3 6-4 win over Japan's Yoshihito Nishioka, and 19-year-old Italian Musetti awaits him on Saturday.

Tsitsipas dropped just four games when he crushed Musetti in an Acapulco semi-final in March, but he senses more of a threat this time from the exciting youngster.

"We played in different conditions. Acapulco was a hardcourt match and with altitude," said Tsitsipas, speaking on Amazon Prime. "The conditions here are different. He's someone who enjoys playing on clay.

"We share a similar game style I think with a one-handed backhand, which is beautiful to see, but tomorrow it's going to be serious business I knew he can play good on this surface. I know he can elevate his game, so it's important for me to be in the semi-finals."

Musetti overcame Slovenian Aljaz Bedene 6-3 7-6 (7-2) in their quarter-final, scrambling through a chaotic second set in which he trailed 5-2 at one stage but then reeled off four straight games, only to fail to serve out.

Thankfully for the youngster, he pulled through the tie-break.

"It was a crazy end," said Musetti. "I was 6-5 up, and at 30-30 played a really bad volley and hit an underarm serve. Sometimes I go out of my mind. I am really proud of myself as I was 2-5 down in the second set and I stayed focused. I tried to play each point at my best."

Russian Karen Khachanov marked his 25th birthday with a 6-1 7-6 (7-3) win over Frenchman Richard Gasquet, veteran doyen of the single-handed backhand.

Khachanov faced a wait to learn who he must face in the semi-finals, however, with Cameron Norrie and Arthur Rinderknech level at one set all overnight, after rain forced an early end to play.

At the Geneva Open, Norway's Casper Ruud will tackle Canadian Denis Shapovalov in Saturday's final.

Ruud saw off Spaniard Pablo Andujar 6-3 6-2, while Shapovalov earned a 6-4 7-5 win against Uruguayan qualifier Pablo Cuevas.

Denis Shapovalov relished feeling much better on court as he impressively bounced back from two consecutive defeats to win at the Madrid Open.

The number 11 seed brushed aside the challenge of Dusan Lajovic on Sunday, winning 6-1 6-3 in the first round.

Shapovalov had suffered disappointment on Thursday when he was knocked out in the second round of the Estoril Open, an event where he was the number one seed.

He has not reached the quarter-finals in his previous two ATP Tour events but won 90 per cent of his first-serve points against Lajovic, hitting 21 winners to his opponent's five.

"Just definitely felt a lot better - I felt very good on the court," Shapovalov said after a 63-minute win in which he did not lose serve. 

"I'm just happy to get the first win.

"Not much can change in the span of a couple of days, but Madrid is a place where I have had a lot of success, from back in juniors to making semis here in the Masters [1000 event] and finals of Davis Cup.

"It's just a place where it kind of feels like home to me and I just feel so comfortable." 

Shapovalov will face Alexander Bublik – who saw off Marton Fucsovics in straight sets – in round two.

Tommy Paul, meanwhile, will play Andrey Rublev after defeating Pedro Martinez.

In the only match of the day to go the distance, Australian Alex de Minaur battled back to triumph 4-6 7-5 6-1 against Jaume Munar.

He will play either Lloyd Harris or Grigor Dimitrov, who are scheduled to do battle on Monday.

Stefanos Tsitsipas battled through to the Miami Open round of 16 and he was joined by Andrey Rublev on Monday.

Greek star and second seed Tsitsipas got the better of 2014 US Open runner-up Kei Nishikori in Miami.

Rublev continued his fine 2021 with a straight-sets demolition of Marton Fucsovics at the ATP 1000 tournament.

In-form Aslan Karatsev, however, bowed out following a surprise loss to Sebastian Korda.

TSITSIPAS HALTS NISHIKORI

Despite a mid-match wobble, Tsitsipas overcame Nishikori 6-3 3-6 6-1 to reach the fourth round.

Former world number four Nishikori forced a deciding set but Tsitsipas withstood the Japanese's comeback.

Tsitsipas, who hit 32 winners, will meet Lorenzo Sonego for a place in the quarter-finals after the 24th seed defeated Daniel Elahi Galan 7-6 (8-6) 6-3.

RUBLEV STAYS HOT

Russian fourth seed Rublev made light work of Fucsovics 6-2 6-1 in just 52 minutes.

Rublev leads the ATP Tour with 18 victories this season after eliminating the in-form Hungarian, ahead of top seed Daniil Medvedev (16-2).

The result secured a third win for Rublev over 29th seed Fucsovics this month.

"I was laughing, because of [the] situation and plus Marton also told me, 'I don't want to see you. I don't want to see you'," Rublev said, cracking a laugh. "[It was] just a situation that [was] fun, and I feel sorry."

Awaiting Rublev is 2014 US Open champion and former world number three Marin Cilic, who beat Lorenzo Musetti 6-3 6-4.

KARATSEV CONQUERED

For only the third time this year, Australian Open semi-finalist and Dubai Tennis Championships winner Karatsev tasted defeat following a 6-3 6-0 loss at the hands of Korda.

American sensation Korda became the first player outside the top five to beat Karatsev this year, with the latter's previous two losses coming against world number one Novak Djokovic and world number four Dominic Thiem.

"It is super special [to reach the Round of 16], especially playing a guy who was as hot as he was," said Korda. "I just took the tactics that I used [against him] at Roland Garros and it worked out really well today."

Diego Schwartzman stands in the way of Korda and the quarters after the fifth seed accounted for Adrian Mannarino 6-1 6-4.

Elsewhere, Denis Shapovalov – the sixth seed – was upstaged by Hubert Hurkacz 6-3 7-6 (8-6).

Another Canadian awaits Hurkacz after 12th seed Milos Raonic was a 6-4 7-5 winner against Ugo Humbert.

Stefanos Tsitsipas continued his strong run of form en route to the Miami Open third round, while Aslan Karatsev's maintained his fairytale run in 2021.

Greek star Tsitsipas flexed his muscles in a straight-sets win over Damir Dzumhur on Saturday.

Australian Open semi-finalist and Dubai Tennis Championships winner Karatsev enjoyed a victorious Miami debut.

Andrey Rublev, Diego Schwartzman, Denis Shapovalov, Marin Cilic and Milos Raonic also progressed at the ATP 1000 tournament.

TSITSIPAS STAYS HOT

World number five Tsitsipas eased past Dzumhur 6-1 6-4 in his first appearance since losing in last week's Mexican Open final.

Tsitsipas (15-4) became the third player to reach 15 wins this season, the second seed following in the footsteps of Russian duo Rublev (17-3) and Daniil Medvedev (15-2).

"It was a great match, especially against a guy that I probably don't have a good record playing against in the past," said Tsitsipas. "I started the match very strong, breaking him twice and taking a big lead in the score, and I think the things worked out by themselves after that."

Tsitsipas will face Kei Nishikori after the Japanese outlasted Aljaz Bedene 7-6 (8-6) 5-7 6-4.

NO STOPPING KARATSEV

Karatsev's Miami Open debut ended in a 6-4 6-3 win for the 17th-seeded Russian over Mikhail Kukushkin.

Already in the ATP's top 100 and set to keep climbing, Karatsev broke serve four times en route to the next round, where Sebastian Korda awaits after upstaging 10th seed Fabio Fognini 1-6 6-4 6-2.

"Of course it gives me confidence to win my first title, but you arrive here and it’s a different surface and new tournament," said Karatsev, who ended last season ranked 112th before bursting into the top 30 behind his semi-final run at Melbourne Park. "So you try [to think of it] as a new tournament and new place, but of course it gives me a lot of confidence."

Karatsev owns a 13-2 record this year, with his only two losses coming against world number one Novak Djokovic and US Open champion Dominic Thiem.

RUBLEV ROLLS ON

Fourth seed Rublev has proven to be remarkably consistent, highlighted by his crushing 6-1 6-2 rain-interrupted victory against Tennys Sandgren.

Having equalled his previous best run in Miami, Rublev will play 29th seed Marton Fucsovics who took down Thanasi Kokkinakis 7-6 (7-3) 6-7 (4-7) 6-4.

Rublev has won a Tour-leading 17 matches this year.

Elsewhere, fifth seed Schwartzman was a 6-3 6-3 winner against Yasutaka Uchiyama, Shapovalov – the sixth seed – trumped Ilya Ivashka 6-7 (5-7) 6-4 6-4 in a marathon, 12th seed Raonic accounted for Jordan Thompson 6-2 6-1, former US Open winner Cilic surprised 13th seed Christian Garin 3-6 7-5 7-6 (7-5), while 15th seed Alex de Minaur was eliminated.

Andrey Rublev's ATP 500 winning streak came to an end at the hands of Aslan Karatsev on a history-making day at the Dubai Tennis Championships.

Rublev had won 23 consecutive matches at this level, second only to Roger Federer (28), but Karatsev finally ended the Russian's remarkable run to progress to his first ATP singles final.

Karatsev, who incredibly went from qualifying to the semi-finals of the Australian Open this year, defeated his compatriot 6-2 4-6 6-4.

He became the first Wild Card to reach the final since Thomas Muster in 1997, doing so by hitting 41 winners and forcing 16 break points – of which he won four – during two hours and 12 minutes on court.

"It was a really tight match [against a] tough opponent," Karatsev said in his on-court interview.

"It was an unbelievable performance [from Andrey]. He didn't lose a match at an ATP 500 in [one year]. Everything was decided in one or two points, I feel happy."

The championship match will be between two first-time Dubai finalists after Lloyd Harris stunned Denis Shapovalov in the other semi-final.

World number 81 Harris, who overcame top seed Dominic Thiem, 14th seed Filip Krajinovic and former US Open finalist Kei Nishikori to reach the last four, came from a set and 4-2 down to defeat world number 12 Shapovalov.

He prevailed 6-7 (5-7) 6-4 7-6 (8-6) to reach a maiden ATP 500 final and become the first qualifier to reach the showpiece in Dubai.

"I don't have many words right now. I am super happy with that win," Harris said on court afterwards.

"Being a set and 2-4 down is mentally and physically a little bit troublesome for me, but I found my best tennis from there. I am just extremely happy with the result right now."

Denis Shapovalov secured a straight-sets win over Jeremy Chardy to set up a semi-final showdown with qualifier Lloyd Harris at the Dubai Tennis Championships. 

The third seed struck 26 winners en route to a 7-5 6-4 triumph on Thursday, but it was his serve that pleased him most.

Shapovalov, ranked 12th in the world, sent down 10 aces as Frenchman Chardy was deprived of any break-point openings.

"I've focused on my serve a lot in the past couple of weeks," the Canadian said.

"I have worked on placing it and tried out different types of serves to have more variation. I hope I can continue that.

"I've also worked on my footwork and positioning during rallies. I am feeling the ball well on both sides. If I am moving well, everything goes into place."

Harris was a surprise winner over Kei Nishikori, sealing a 6-1 3-6 6-3 success to dump out the former world number four.

Second seed Andrey Rublev defeated Marton Fucsovics 7-5 6-2 and will now face fellow Russian Aslan Karatsev.

Wildcard Karatsev continued his run with a hard-fought victory over teenager Jannik Sinner, coming from a set down in a 6-7 (5-7) 6-3 6-2 win.
