Novak Djokovic smashed one racket and threw another into the stands on the way to losing his bronze medal match at the Tokyo Olympics on Saturday.

Spain's Pablo Carreno Busta beat the world number one 6-4 6-7 (6-8) 6-3 to finish third in men's singles.

The shock result followed a day on from Djokovic's hopes of a Golden Slam being crushed by defeat to Alexander Zverev in the semi-finals.

In the wake of his singles third-place match setback, Djokovic also pulled out of the mixed doubles bronze match, citing a left shoulder injury.

Having already clinched the Australian Open, French Open and Wimbledon titles, Djokovic was eyeing gold at the Games before heading to the US Open in August, aiming to land the five biggest prizes in tennis in the same season.

That has never been achieved in a calendar year by a man, and Djokovic could not even manage a consolation prize from his singles mission in Japan. How serious his injury is now remains to be seen.

After levelling the singles match by taking the second-set tie-break, Djokovic boiled over in the first game of the decider, firstly when flinging his racket several rows back from the middle of the court after Carreno Busta put away a volley at the net.

Djokovic picked another racket from his bag but petulantly demolished that against a net post after dropping the third game to slide 3-0 behind, receiving a warning from the umpire for that violent outburst.

His anger may have been explained by injury or by his disappointment on Friday, when, as well as losing to Zverev, Djokovic and Serbian team-mate Nina Stojanovic were beaten in the semi-finals of the mixed doubles.

Djokovic would have had one final shot at a medal from his Tokyo trip to come later on Saturday, with the 34-year-old and Stojanovic due to face Ash Barty and John Peers in another match for bronze.

However, shortly after his singles exit, it was announced that Djokovic had pulled out of that match, handing Barty and Peers the medal.

Amid the anger and frustration exhibited on court by Djokovic, it was a banner day for Carreno Busta, as Spain celebrated another tennis medal, having won at least one in eight of the last nine Olympics.

The 30-year-old fell to the court in joy at the end of the two hours and 47 minutes it took him to defeat the world number one, his elation a sharp contrast to the emotions of his beaten opponent.

Top seed Casper Ruud is through to his third successive ATP final after defeating Arthur Rinderknech at the Generali Open.

The world number 14 has been in incredible form on clay, having captured the Swedish Open and Swiss Open titles.

Ruud, who also landed the Geneva Open crown in May, has now won his last 11 matches, but was made to work hard for a 6-3 7-6 (9-7) victory over world number 91 Rinderknech in Kitzbuhel.

The Norwegian was forced to come from behind and defeat Sweden’s Mikael Ymer on Thursday, saving a match point in the process, and a single break swung a close opening set in his favour.

Fresh from defeating third seed Filip Krajinovic in the last eight, Rinderknech refused to lie down and took the second to a tie-break.

The big-serving Frenchman fired down 10 aces, but Ruud held his nerve to avoid a decider and prevail, saving a match point as he came from a mini-break down to extend his winning run.

The 22-year-old will play Pedro Martinez in the final after the Spaniard came from behind to beat Germany’s Daniel Altmeier 4-6 6-3 6-3.

Spaniard Martinez won 70 per cent of points behind his first serve and broke four times to move into the championship match.

Alexander Zverev apologised to Novak Djokovic after ending the Serbian superstar's hopes of a glorious Golden Slam – but joked it was about time someone else landed a major tennis title.

In their Olympic Games semi-final, it seemed Djokovic was cruising through to the gold medal match when he surged a set and a break of serve ahead.

Incredibly, though, Zverev won 10 of 11 games from 3-2 behind in the second set to take the match 1-6 6-3 6-1 and set up a shot at Karen Khachanov in Sunday's final.

Djokovic swept to Australian Open, French Open and Wimbledon trophy success before heading to Japan for the Olympics, the fourth leg of a potential sweep of each of the year's majors and the Tokyo 2020 singles title.

He had spoken of it becoming closer to a reality, as he attempted to match Steffi Graf's achievement from 1988, when she followed triumphs at each of the slams by winning in the October 1 final at the Olympics, held in Seoul that year. Graf remains the only player to have pulled off the feat in the same year.

Zverev had other ideas, but he also had sympathy for Djokovic when they exchanged words at the net.

"I told him that he's the greatest of all time, and he will be," Zverev said.

"I know that he was chasing history, chasing the Golden Slam and chasing the Olympics, but in these kind of moments me and Novak are very close. Of course I'm happy that I've won, but at the end of the day I know how Novak feels.

"I feel sorry for Novak, but he's won 20 grand slams, 550 Masters Series or whatever, you can't have everything.

"He's the greatest player of all time, he will win the most grand slams out of anybody on tour, but I'm also happy that I'm in the final."

Victory at Wimbledon earlier in July took 34-year-old Djokovic to 20 grand slam titles, level with Roger Federer and Rafael Nadal for the most by a man in the history of tennis, and Zverev was lurching towards becoming his latest victim when their Tokyo tussle began in a one-sided manner.

"I was down a set and a break, so I needed to change something. I started playing much more aggressive," Zverev said. "I started to swing through the ball a little bit more, and I tried to dominate that way."

Zverev is assured of at least a silver medal now, while Djokovic faces a bronze medal play-off against Spain's Pablo Carreno Busta.

"It's an amazing feeling knowing that you're going to bring the medal back to your house, back home to Germany," Zverev said.

"It's incredible beating the best player in the world undoubtedly right now and in this season. It seemed it was impossible to beat him at this event, so I’m very happy right now. But yet there's still one match to go."

Novak Djokovic's hopes of becoming the first man to win a calendar Golden Slam were crushed by a semi-final defeat to Alexander Zverev at the Tokyo Olympics.

From a set and a break up, Djokovic dropped a staggering eight games in a row on his way to a 1-6 6-3 6-1 loss.

The 34-year-old Serbian had been unsure about coming to the Games but was swayed by the pride he takes in representing his country and the tantalising opportunity to add a gold medal to a potential clean sweep of the grand slams.

He has already won the Australian Open, French Open and Wimbledon, and will head to the US Open in August as a heavy favourite regardless of this setback.

But this was just not Djokovic's day, despite him making a whirlwind start and dominating until the point he broke to lead 3-2 in the second set. From there, Zverev seized control. 

When Djokovic volleyed into the net to make it 3-3, dropping serve for the first time in the match, it looked like just a minor stumble.

Yet suddenly he was struggling for form and did not win another game until he was already 4-0 behind in the deciding set.

Zverev was playing blindingly brilliant tennis and was proving obdurate too, saving four break points in the second game of the third set.

He clinched victory with a blazing backhand winner, and goes on to face Russian Karen Khachanov in the final.

The result means Djokovic, like Roger Federer, seems fated never to win the Olympic singles gold medal. And it leaves Steffi Graf as the only player to ever win a calendar Golden Slam, having done so in 1988 when she added the Seoul Olympics title to her haul of majors.

Russian Olympic Committee's Khachanov fended off Spain's Pablo Carreno Busta with some ease in the first semi-final, with the world number 25 sweeping to a 6-3 6-3 victory in an hour and 19 minutes.

He won 26 of 28 points on first serve to freeze out Carreno Busta, who had only one break point all match and could not take that opportunity.

"It's just a pure happiness, a pleasure to be here to live those moments, these kind of memories will stay forever," Khachanov said.

Khachanov delivered a rock solid display, with his serve and forehand at their best, barely giving his opponent a sniff of an opportunity as the Moscow-born 25-year-old established a firm grip.

"That's the way I prepared, against every opponent you play a little bit differently," Khachanov said. "The final will be another story, another match, another day. I hope it will be the same."

Carreno Busta, who will face Djokovic for the bronze medal, said: "It was not the best match I have played, but Karen was unbelievable today, playing very aggressive and serving really good."

Casper Ruud survived a scare as he progressed to the Generali Open semi-finals with a 3-6 7-6 (7-5) 6-1 victory over Mikael Ymer.

World number 14 Ruud is targeting a third successive ATP title, having also captured the Swedish Open and Swiss Open earlier this month.

It has been a timely return to form for the Norwegian, who suffered a shock defeat to Australia's Jordan Thompson at Wimbledon at the end of June.

Although he was in danger of seeing his nine-match winning streak come to an end in Kitzbuhel, after losing the opening set against Swedish opponent Ymer.

Ruud, who also triumphed at the Geneva Open in May, was then taken to a tie-break in the second ser by the world number 99, but held his nerve to tee up a decider.

It was one-way traffic from there with the 22-year-old dominating play to set up a last-four clash with Arthur Rinderknech, who hit five aces as he overcame third seed Filip Krajinovic 6-4 6-1.

Meanwhile, Daniel Altmaier's place in the semi-finals was secured with a 6-1 6-7 (5-7) 6-3 win over Gianluca Mager.

The world number 135, who reached the fourth round of last year's French Open, will play Pedro Martinez in the semi-finals after the Spaniard saw off Jozef Kovalik 6-2 6-2.

Novak Djokovic cruised through to the men's singles semi-finals after a commanding straight-sets victory over Kei Nishikori at the Ariake Tennis Park.

The world number one is yet to drop a set at the Tokyo Games after running out a 6-2 6-0 winner against home favourite Nishikori, who claimed bronze in Rio five years ago.

Having already won the Australian Open, French Open and Wimbledon this year, Djokovic is aiming to become the first male player of the Open era to complete the Golden Grand Slam.

Should he claim gold in Tokyo and go on to triumph at the US Open, he would become only the second player overall to achieve the feat, after Steffi Graf in 1988.

However, the Serbian has never reached an Olympic final – his best result coming in for the form of a bronze medal in Beijing.

"Matches are not getting easier, but my level of tennis is getting better and better," Djokovic told reporters after setting up a last-four tie with Alexander Zverev.

"I've done that many, many times in my career. I know that I'm the kind of player that the further the tournament goes, the better I'm feeling on the court.

"That's the case here, [it was] my best performance of the tournament tonight against a very good opponent."

DANIIL DUMPED OUT

Standing in the way of Djokovic and a shot at the gold medal is fourth seed Zverev.

The big-serving German saw off Jeremy Chardy 6-4 6-1 and like Djokovic is yet to drop a set at the tournament.

World number five Zverev, who hit 11 aces during the contest, broke early on the way to edging a closely fought opening set. The US Open finalist then went into overdrive with three breaks on the way to sealing the deal.

There was, however, no joy for second seed Daniil Medvedev, as he went down 2-6 6-7 (5-7) against Spain's Pablo Carreno Busta, who is looking to replicated Rafael Nadal's effort from 2008.

"Today, he could win a Masters easily, and yet he's never been in any final of those," the Russian said of his opponent.

"With the level he showed here today, he can get to the final of a Grand Slam easily. I couldn't play better than what I did today. It was not easy to play and I'm really disappointed with myself and for my country to lose in the quarters."

FROM RUSSIA WITH LOVE

Despite Medvedev's exit, Russia – or, at least, the Russian Olympic Committee – will be represented in the semi-finals by Karen Khachanov.

A quarter-finalist at Wimbledon earlier this month, the 12th seed built on his momentum by overcoming Ugo Humbert in three sets.

Khachanov took the opener on a tie-break but was pegged back by the Frenchman in the second as the contest went to a decider.

But he established early control by breaking to love in game four before holding out to prevail 7-6 (7-4) 4-6 6-3.

World number 16 Roberto Bautista Agut crashed out in the second round as the other favourites for the Generali Open battled through.

Bautista Agut lost the first set to Spanish compatriot Pablo Martinez in Kitzbuhel, Austria, and could not complete a comeback despite forcing a decider as he lost 6-4 6-7 (5-7) 7-5.

Top seed Casper Ruud, who won last week in Gstaad to claim his third ATP Tour crown of 2021 and fourth in total, came from 4-2 down in the first set to win 7-5 5-7 6-4 against Mario Vilella Martinez.

Third seed Filip Krajinovic survived a second-set scare to beat Carlos Taberner 6-3 2-6 6-4.

Arthur Rinderknech, who dispatched of fifth seed Federico Delbonis on Tuesday, awaits Krajinovic in the next round.

The other clash on Wednesday saw Sweden's Mikael Ymer cruise past home favourite Alexander Erler 6-2 6-3 to secure a quarter-final berth.

Ymer will now face the thankless task of challenging 22-year-old Ruud for a spot in the semi-finals.

Daniil Medvedev did not take kindly to a question over the controversy surrounding Russian athletes at the Tokyo Olympics after he battled through sweltering conditions to reach the quarter-finals.

Medvedev beat Italy's Fabio Fognini 6-2 3-6 6-2 on Wednesday in a match that was paused for 10 minutes due to on-court temperatures reaching 31 degrees Celsius, with humidity then adding to that.

The world number two had to receive medical attention on two occasions before he prevailed to tee up a last-eight tie with Pablo Carreno Busta of Spain.

Top seed Novak Djokovic continued his march towards the medal matches with a routine win over Alejandro Davidovich Fokina, though in the doubles, Andy Murray's hopes of winning a historic fourth Olympic prize were shattered.

MEDVDEV'S TEMPER FRAYS IN THE HEAT

It had already been a stressful day for Medvedev. The 25-year-old replied "I can finish the match but I can die. If I die, are you going to be responsible?" when asked by chair umpire Carlos Ramos whether he could carry on playing against Fognini following two medical timeouts. 

Medvedev's temper then boiled over in the media mixed zone when he was questioned over the contentious nature of Russian athletes competing at the Games.

The Russian flag is not represented in Tokyo due to sanctions against the country for state-sponsored doping offences. Russia is suspended from competing in global sporting events for two years – a ban that was reduced from an initial four-year punishment. Instead, athletes are competing under the banner of the Russian Olympic Committee (ROC).

Medvedev was asked if he feels the Russian athletes are "carrying a stigma of cheaters".

Seemingly misunderstanding the question, Medvedev hardly held back in his reaction, saying: "That's the first time in my life I’m not gonna answer a question, man. And you should be embarrassed of yourself."

Before leaving the room, Medvedev subsequently told the press officer: "I think you should [remove] him from either the Olympic Games, either the tennis tournament. I don't wanna see him again in my interviews. Thanks."

MURRAY'S PARIS PARTICIPATION IN DOUBT

There was to be no fairytale title tilt for former world number one Murray. He won gold in the singles in London and Rio, and also managed a silver medal at the 2012 Games in the mixed doubles, but he and Joe Sailsbury suffered a defeat to Croatian pair Marin Cilic and Ivan Dodig in the quarter-finals.

The British pair won the first set but failed to make their advantage count, with Croatia's duo coming back to win 4-6 7-6 (7-2) 10-7.

Murray will be 37 by the time the Paris Games come around, and as he continues to carefully manage his return from hip surgery, the Scot could well have made his Olympic farewell.

"I don't know. I don't know if I'll get the opportunity to play [in the Olympics] again," he conceded.

"I love every minute of playing the Olympics. I wish that today would have gone differently. I had another chance with Joe to win a medal. We were so close and that is just disappointing. There was some stuff I wish I could have done at the end of the match to try and help out more. But yeah, very disappointing."

MIXED BAG FOR TSITSIPAS

While Medvedev, Djokovic and Alexander Zverev all progressed into the last eight in the singles, there was no place for Stefanos Tsitsipas, whose hopes were ended by Ugo Humbert.

The Greek world number four suffered a seemingly innocuous leg injury in the second set tie-break and failed to recover in the decider as Frenchman Humbert claimed the biggest win of his career.

However, Tsitsipas was swiftly back on court to play in the mixed doubles alongside partner Maria Sakkari, and the duo claimed a comfortable 6-3 6-4 victory over Canada's Gabriela Dabrowski and Felix Auger-Aliassime.

Asked after that win to discuss what went wrong in his earlier defeat, Tsitsipas replied: "I figured out a few things later during the match, like really, really late. 

"I think if I've had the same mindset or the same attitude, same vision that I had towards the very end of the match, I think things would have gone much, much smoother and better for me. It's something that I learned."

He also confirmed his injury was "nothing serious."

DJOKOVIC ON A ROLL

As expected, Djokovic is one win away from a shot at a medal in the singles, and he then followed up his victory over Davidovich Fokina by combining with Nina Stojanovic in the mixed doubles.

The Serbian pair beat Marcelo Melo and Luisa Stefani of Brazil 6-3 6-4 in just 70 minutes to book their place in the next round.

Djokovic will have the host nation against him in his next match, however, as he takes on Kei Nishikori, who is Japan's only hope of a singles medal after Naomi Osaka's exit.

The International Tennis Federation (ITF) has confirmed matches at the Tokyo Olympics will now start later in the day after concerns over player health and welfare.

World numbers one and two Novak Djokovic and Daniil Medvedev have been among the players to complain about games starting too early in the day, citing the heat and humidity at Ariake Tennis Park as a major issue.

Indeed, on Wednesday, 25-year-old Medvedev struggled with the conditions as he battled to a 6-2 3-6 6-2 win over Fabio Fognini.

Despite being allowed 10 minutes off court at one stage, Medvedev was in visible discomfort during the last-16 tie, and had two medical timeouts before being asked by chair umpire Carlos Ramos whether he could continue.

"I can finish the match but I can die," the Russian replied to Ramos, per ESPN. "If I die, are you going to be responsible?"

The 72 per cent humidity meant 31 degrees Celsius felt like 37 degrees Celsius on the heat index. Medvedev was not the only player to suffer on Wednesday, with Paula Badosa having to be taken from the court in a wheelchair as she retired against Marketa Vondrousova due to heatstroke.

Earlier in the week, Medvedev had questioned the approach of starting matches in the late morning, while top seed Djokovic suggested scheduling the first games for 15:00 local time.

The ITF has now agreed, with start times pushed back to 15:00, meaning the majority of matches in the closing stages of the Olympic tennis will be played during the slightly cooler evening hours.

"In the interests of player health and welfare and following extensive consultation, the ITF has announced a change of schedule due to the increasing heat and humidity currently being experienced in Tokyo," an ITF statement read.

"The decision to start matches at 3pm JST from Thursday is possible due to the outcomes of today’s matches across the five competitons being staged and the size of the player field.

"[The decision] is designed to further safeguard player health."

Federico Delbonis and Laslo Djere crashed out of the Generali Open in the first round on Tuesday.

Fifth seed Delbonis and sixth seed Djere were the highest-ranked players in action on day two, but both fell to surprise defeats.

Delbonis, a recent semi-finalist at the Hamburg European Open, was convincingly beaten 6-2 6-4 by Arthur Rinderknech.

Frenchman Rinderknech fired down 10 aces and was only broken once in the contest.

Djere, meanwhile, put up more of a fight but ultimately succumbed to Daniel Altmaier, who won 4-6 6-3 6-3 in a battle lasting two hours and 10 minutes.

World number 50 Djere had also made the semi-finals in Hamburg and followed that up with another run to the last four at the Swiss Open Gstaad.

But his run of form came to an end as German Altmaier – who himself enjoyed a semi-final run in Croatia last week – booked a last-16 tie meeting with Marco Cecchinato after breaking Djere on six occasions.

Cecchinato had beaten Radu Albot in straight sets to reach the next round while qualifier Jozef Kovalik saw off Jaume Munar with a 6-4 6-4 victory.

The top four seeds, including number one Casper Ruud, will begin their campaigns at the ATP 250 event in Kitzbuhel on Wednesday.

Kei Nishikori was as surprised as anybody by Naomi Osaka going out of the Tokyo Olympics, but stressed it did not add to pressure on his shoulders.

Japan's two standard-setters in tennis are at opposite ends of their careers, with Nishikori seemingly in a slow decline and Osaka expected to add significantly to her four grand slams.

But the focus on the Japanese public looks set to switch to Nishikori for the rest of the tennis, after he reached the last-16 stage with a 7-6 (7-5) 3-6 6-1 win over American Marcos Giron on Tuesday.

Former world number four Nishikori and Ben McLachlan are through to the doubles quarter-finals too, which may be a likelier route to a medal.

Nishikori already has a bronze to his name from the 2016 Games, where he beat Rafael Nadal in the third-place match.

When asked whether he felt expectations shifting from Osaka on to his shoulders, after she lost to Marketa Vondrousova, Nishikori said: "Not really. I just need to focus on what I have to do on the court.

"It's very sad, of course, that Naomi lost and a surprise. But I knew she had a lot of pressure, this is her first time in the Olympics and I know it's not easy.

"I didn't see her match today, so I cannot say much."

Should Nishikori, now down at 69th in the rankings, beat Ilya Ivashka of Belarus on Wednesday, that could set up a quarter-final against hot favourite Novak Djokovic.

REVENGE FOR VILLAGE FAN TSITSIPAS

It was a weary Stefanos Tsitsipas who was pummelled in the first round of Wimbledon by Frances Tiafoe last month. On Tuesday, a more predictable outcome manifested as Greece's great hope scored a 6-3 6-4 victory over his American opponent.

That loss in London came barely a fortnight after Tsitsipas suffered a heartbreaking loss to Djokovic in the French Open final, from two sets up, and he was succinct with his verdict about what was different this time.

"Concentration and attention levels," was the Tsitsipas assessment.

Next for him is a testing third-round tussle with French shot-maker Ugo Humbert, and Tsitsipas will want to hang around, having been charmed by the Olympic Village experience after so long in the tennis bubble.

"It's a different contrast, it's a different approach completely," Tsitsipas said. "I've made friendships, connected with some other athletes. It's nice to be able to experience something like this. I find the Olympics are really a nice sports event.

"I met a big tennis enthusiast from India. He's doing shooting and we became good friends. I met some of the other Greek athletes, table tennis players, and rowers from different countries."

BRILLIANT BROADY

Liam Broady was a late addition to the Olympics draw and is making the most of the opportunity, with the unheralded British left-hander scoring a terrific 7-5 3-6 6-3 second-round win over Wimbledon semi-finalist Hubert Hurkacz.

Frenchman Jeremy Chardy awaits Broady after beating Russian Olympic Committee's Aslan Karatsev in three sets.

There were also wins on Tuesday for Karatsev's countryman Karen Khachanov and Argentinian Diego Schwartzman, while Wednesday's programme features the entire third-round line-up, including Djokovic's clash with Spain's Alejandro Davidovich Fokina.

Andy Murray said the quad injury that ruled him out of defending his men's singles title at Tokyo 2020 has not been troubling him in matches, but his withdrawal was due to concerns over results showing up in scans.

The Olympic champion in 2012 and 2016 opted to pull out of the singles prior to his scheduled first-round showdown against Felix Auger-Aliassime on Sunday. 

Instead, Murray decided to continue in the doubles alongside Joe Salisbury, where the pair made the quarter-finals on Tuesday by beating German duo Kevin Krawietz and Tim Puetz 6-2 7-6 (7-2).

It means Murray remains on track for a third straight Olympic gold and he offered a bit of insight behind his decision not to play in the singles.

"I've had a bit of an issue with my quad," he said.

"It's actually not really been causing me many issues on the court like in practice or anything, there was just some stuff showing on the scans that made all the medical team a bit wary about it.

"I said to Joe that if he picked me to play doubles with him then I'd prioritise the doubles over the singles if I had any physical issues and that was the case. 

"It's disappointing for me because I do feel like I've been playing well, and I've loved the Olympics and I would've liked the opportunity to defend my title. 

"But that wasn't to be and now all the focus and energy goes towards the doubles and to try our best to get a medal there."

Marin Cilic and Ivan Dodig await Murray and Salisbury in the last eight.

Pedro Martinez outlasted Lucas Pouille to set up a second-round clash with fellow Spaniard Roberto Bautista Agut at the Generali Open.

World number 97 Martinez came through Monday's longest match, which lasted two hours and 43 minutes, as a 6-3 6-7 (4-7) 6-4 winner.

Mikael Ymer, who reached the quarter-finals of last week's Swiss Open Gstaad, is also through to the second round in Austria after battling past Pablo Cuevas 6-3 7-5.

Qualifier Jozef Kovalik will face Jiri Vesely for a place in the quarter-finals, meanwhile, after beating ninth seed Jaume Munar in straight sets.

Also through on Monday was lucky loser Carlos Taberner, who took advantage of his second chance by battling from a set down to overcome Thiago Seyboth Wild 3-6 6-3 6-2.

World number one Novak Djokovic made light work of Jan-Lennard Struff to continue his progress at the Olympic Games, and he revealed he is thriving off the energy in Tokyo as he copes with the weight of expectation.

Djokovic is aiming to complete a Golden Slam this year, having already swept up the Australian Open, French Open and Wimbledon titles.

Olympic gold is next on his list, before the Serbian will head to the US Open.

Struff was no match for the 34-year-old on Monday, as he teed up a round-of-16 tie with Alejandro Davidovich Fokina by beating the German 6-4 6-3.

Djokovic will be joined by fellow favourites Alexander Zverev and Daniil Medvedev, as the singles competition begins to hot up.

DJOKOVIC THRIVING IN TOKYO

Djokovic is aiming to become the first man in the Open Era to complete a Golden Slam, though even if he did not have such a feat in his sights, he would still have the expectation of clinching gold, given Roger Federer and Rafael Nadal chose not to compete.

"I think that once you reach the top spots of the rankings and start winning slams, you're going to experience different kinds of expectations and pressure from yourself and from people around," Djokovic said.

"It's kind of a normal thing that a lot of athletes from our sport have been experiencing in the past and it's going to happen in the future."

The 20-time grand slam champion also revealed he is splitting his time between a hotel and the Olympic athletes' village, as he looks to soak up the atmosphere in Tokyo, despite the ongoing coronavirus restrictions.

"I only stayed in the Olympic village the first few days in Rio, then I moved when the competition started to the hotel," he explained.

"Here, I'm between the hotel and the village but I'm spending every single day in the village mostly and the hotel is mostly for sleeping over, basically, and having my own routine in the morning.

"Other than that, I'm always in the village because it's just so special. Most of the tournaments I'm in a hotel anyway and this [Olympic Games] happens once in four years. Of course, I try to balance things out with keeping my own routines and things that make me feel good, but I'm thriving also on that wonderful energy in the village."

SPIDERCAM FACES ZVEREV'S WRATH

Alexander Zverev moved confidently into the round of 16, defeating Colombia's Daniel Elahi Galan Riveros 6-2 6-2 in just 71 minutes.

In fact, his greatest nemesis was the spidercam, which came a little too close for the German's comfort.

Zverev clipped a ball at the camera suspended above his head as he prepared to serve – the world number five claiming he almost hit the wire holding the device in place when he threw the ball.

"It was three meters above me, I almost hit the wire rope when I was throwing the ball. It just hung too low," he said, though the chair umpire disagreed.

There was ultimately no negative impact on Zverev's performance, and the 24-year-old will face Georgia's Nikoloz Basilashvili for a place in the last eight.

Basilashvili got the better of Italian world number 26 Lorenzo Sonego 6-4 3-6 6-4 to secure his progression.

MEDVEDEV MAKES HIS CLASS COUNT

The gulf in quality between Daniil Medvedev and Sumit Nagal of India was clear to see, as the world number two – who is representing the Russian Olympic Committee – cruised through in just 66 minutes.

Nagal, ranked 160th in the world, dropped serve in the first game of the match and never looked likely to recover, and the Australian Open runner-up breezed into the next round 6-2 6-1.

Medvedev will next go up against Italy's Fabio Fognini. The Russian has faced the world number 31 on four occasions, winning three times.

MURRAY (NO, NOT THAT ONE) DROPS OUT

Great Britain's Olympic team had a day to remember on Monday, but Jamie Murray and his doubles partner Neal Skupski could not carry on their run.

Kei Nishikori and Ben McLachlan, representing hosts Japan, got the better of the British duo 6-3 6-4.

Murray – whose brother Andy is also competing in the doubles but has withdrawn from the singles, in which he was defending champion – was called up as a late replacement for Dan Evans.

He has not made it past the second round in four Olympic Games, despite having won seven grand slam doubles titles.

Carlos Alcaraz won his first of possibly many ATP Tour titles on Sunday with an emphatic victory over Richard Gasquet at the Croatia Open. 

The 6-2 6-2 win in Umag meant 18-year-old Alcaraz became the youngest tour-level champion since Kei Nishikori won at Delray Beach in 2008, also aged 18.

Despite his tender years, seventh seed Alcaraz was too hot to handle for Gasquet, the highly rated Spaniard cruising past his significantly more experienced opponent in one hour and 17 minutes.

"I had a lot of good moments in this tournament. I beat five great tennis players," Alcaraz told atptour.com.

"I think that I grew up a lot in this tournament and I keep a lot of experience from this tournament. It's going to be useful for the future."

Gasquet, who needed more than three hours to overcome Daniel Altmaier in the last four, was hoping to win his first tour title since 's-Hertogenbosch in 2018.

"It was tough for me to play [with] full intensity. I had a tough match yesterday. It was tough, and especially with a guy like Carlos, who is playing really fast with a lot of energy and spin," Gasquet said.

"He’s playing unbelievable. He’s only 18 and of course he has a great future and I just couldn’t play at his level and his intensity.

"That was the key of the match and he didn't lose a point. He played well, very solid. He's a great player."
