Alexander Zverev was given a thorough examination of his Paris Masters credentials by Grigor Dimitrov, but the fourth seed progressed nonetheless to reach the last eight.

Zverev, who last in last year's final, saw match points slip from his grasp in the second set as Dimitrov levelled the match, however, he eventually prevailed on Thursday.

World number one Novak Djokovic benefited from a walkover, while Daniil Medvedev also moved through to the quarter-finals of the ATP Masters 1000 event.

Zverev outlasts Dimitrov

Olympic Games gold medallist Zverev had to dig deep for his 7-6 (7-4) 6-7 (3-7) 6-3 win over former world number three Dimitrov.

It was Zverev's seventh win on the bounce, but he was well aware of just how deep he had to dig to see off a resilient Dimitrov.

"Incredible match," Zverev, who won a fifth tour title of the year last week at the Vienna Open, said afterwards. "Grigor is playing very high-level tennis and I had to leave everything out there.

"I think it was a very high-level match and it could have gone both ways, especially the third set. I am happy with how things went in the end."

Djokovic moves through without playing

There was no such ordeal for top seed Djokovic, however.

Djokovic – a 20-time grand slam champion – received a walkover after Gael Monfils was advised not to continue with the tournament due to an adductor issue sustained in his previous win over Adrian Mannarino.

Taylor Fritz awaits five-time Paris champion Djokovic after the American saw off 10th seed Norrie 6-3 7-6 (7-3), while Casper Ruud will tussle with Zverev.

Ruud's emphatic 6-2 6-1 demolition of Marcos Giron clinched a historic achievement for the 22-year-old – who became the first Norwegian to qualify for the ATP Finals at the end of a breakthrough year in which no player can better his five tour-level titles.

Hubert Hurkacz did his chances of joining Ruud in Turin no harm as the Polish seventh seed – who holds the last automatic qualifying berth – fought back to defeat Dominik Koepfer 4-6 7-5 6-2 and set up a meeting with James Duckworth, who beat Alexei Popyrin 7-6 (8-6) 6-4.

Second seed and US Open champion Medvedev was another who had to come from behind before ultimately seeing off Sebastian Korda 4-6 6-1 6-3.

He will go up against Hugo Gaston, who became the first French qualifier to reach the Paris Masters quarter-finals since 1990 with his win over Carlos Alcaraz.

Gael Monfils has withdrawn from the Paris Masters due to an adductor problem, handing world number one Novak Djokovic a walkover into the quarter-finals.

Djokovic has played only once on the ATP Tour since losing the US Open final to Daniil Medvedev on September 12.

That defeat at Flushing Meadows ended Djokovic's hopes of achieving a calendar Grand Slam, though the Serbian has returned to action for the final few weeks of the 2021 season.

With the ATP Finals coming up, Djokovic headed to Paris looking to regain the title he claimed in his last appearance in the tournament back in 2019. He needed three sets, but overcame Marton Fucsovics 6-2 4-6 6-3 in his first match.

He has won the Paris Masters on five occasions and is the top seed this time around, with defending champion Medvedev seeded second. 

Monfils, seeded 15th, beat Miomir Kecmanovic and Adrian Mannarino en route to the last 16, but confirmed to the media on Thursday that he had been advised not to continue.

Djokovic will face the winner of Cameron Norrie, who recently triumphed at Indian Wells, and Taylor Fritz in the quarter-finals.

The field has already been cleared of third seed Stefanos Tsitsipas, who retired hurt when facing Alexei Popyrin on Wednesday.

Teenage sensation Carlos Alcaraz put in an impressive display to upstage eighth seed Jannik Sinner in straights sets in the third round of the ATP Paris Masters on Wednesday.

Alcaraz was on top for most of his 7-6 (7-1) 7-5 victory, winning 80 per cent of his first-serve points and 75 per cent of net points against Sinner.

Sinner showed determination to stay in both sets, with the Italian saving nine of the 11 break points he faced, but it was ultimately in vain.

The European Open winner will be among those sweating as the race to qualify for the ATP Finals in Turin heats up.

After the win, 18-year-old Alcaraz said: "I'm so happy for this win as Jannik was fighting for a spot at the ATP Finals. It's my third Top 10 win of the year.

"I think Jannik and I will have a great rivalry in the future... I think that I played really, really aggressive, more than him. I think that was one of the keys."

Alcaraz will now face qualifier Hugo Gaston in the next round after the Frenchman impressively knocked out 12th seed Pablo Carreno Busta 6-7 (3-7) 6-4 7-5.

Interesting day for Turin hopefuls

It was a mixed day for others looking to secure a spot at the season-ending ATP Finals later this month as Felix Auger-Aliassime – ranked 12th in the ATP Race to Turin – lost in straight sets to Dominik Koepfer, who added to his impressive list of victims after beating three-time grand slam champion Andy Murray in the first round.

Koepfer will play another Turin hopeful, the 10th-ranked Hubert Hurkacz after he beat Tommy Paul in straight sets.

Cameron Norrie also impressed in his 6-3 6-4 win over Reilly Opelka, which was his 50th tour-level win of the year.

Taylor Fritz awaits after the American stunned fifth seed Andrey Rublev 7-5 7-6 (7-2).

Medvedev and Zverev ease through but Tsitsipas out

Second seed and US Open champion Daniil Medvedev had a routine first match of the tournament as he swept past Ilya Ivashka 7-5 6-4, while Olympic Games gold medallist and fourth seed Alexander Zverev also had few problems against Dusan Lajovic 6-3 7-6 (7-5).

However, third seed Stefanos Tsitsipas exited after retiring hurt with an apparent arm injury against Alexei Popyrin in the first set with the score at 4-2 to the Australian.

Popyrin will now face fellow countryman James Duckworth, who followed up his impressive win against 14th seed Roberto Bautista Agut with a 6-3 3-6 6-3 victory against Lorenzo Musetti.

Elsewhere, 11th seed Diego Schwartzman was shocked by qualifier Marcos Giron 7-6 (7-2) 7-6 (7-4).

There were also wins for 16th seed Grigor Dimitrov against Karen Kachanov, and Sebastian Korda over Marin Cilic.

Gael Monfils will go up against world number one Novak Djokovic in the third round after the experienced French 15th seed came from behind to beat compatriot Adrian Mannarino 2-6 7-6 (7-4) 6-2.

Novak Djokovic recovered from a second-set blip to emerge victorious 6-2 4-6 6-3 in his first match since the US Open at the Paris Masters.

Victory in Paris would see Djokovic – competing for the first time since September's loss to Daniil Medvedev in the Flushing Meadows final – clinch the year-end number one ranking for a record seventh time.

Djokovic looked to be on course for a routine victory to start his campaign after comfortably taking the first set against Marton Fucsovics in their second-round contest on Tuesday.

However, the top seed's Hungarian opponent fought back to force a decider, hitting 13 winners to seven unforced errors in the second set.

But Djokovic – a record five-time Paris Masters champion – ensured a remarkable turnaround was not forthcoming, breaking Fucsovics twice in the third and, after letting one match point slip, clinching his second to secure victory.

Felix fights back

Ranked 12th in the ATP Race to Turin, Felix Auger-Aliassime needs to lift the trophy in Paris and hope Casper Ruud and Jannik Sinner do not reach the latter stages to make it to the ATP Finals.

Auger-Aliassime risked falling at the first hurdle on Tuesday as the ninth seed was forced to fight back to defeat Gianluca Mager 4-6 6-4 6-1.

"I had difficulty with my pace at the beginning of the match," said Auger-Aliassime. "I didn't hit enough first serves so I had a bit of pressure on my second serve.

"So I could have served better in the first set. I [had] a poor game at four-all and I got broken, but even before that there were moments at 30-all it was a bit hot and a bit tight. I think I relaxed. I found a better pace at the beginning of the second set, and it went even better as the match went forward."

He will next face Dominik Koepfer in the second round following the German's stunning win over Andy Murray on Monday.

Alcaraz sets up Sinner clash

Sinner will have an extremely testing second-round clash after Carlos Alcaraz came from behind to see off wild card Pierre Hugues-Herbert.

Alcaraz let slip a 4-2 lead in the first set to lose that on a tie-break but won six straight points in a second-set breaker before eventually battling to a 6-7 (4-7) 7-6 (7-2) 7-5 win in two hours, 53 minutes.

"It's not easy to play against a home player," Alcaraz said. "I think we played a good level and it was a great match, so I am happy to win. He has a great serve, so I had to return better and remain focus. I think that was the key. I am playing at a good level and I want to finish the year strong."

Diego Schwartzman – the 11th seed – needed three sets to see off John Millman, 15th seed Gael Monfils reversed a one-set deficit against Miomir Kecmanovic and 16th seed Grigor Dimitrov survived a three-setter with Richard Gasquet.

But one seed did fall on Tuesday, Roberto Bautista Agut (14) edged by James Duckworth in three sets.

Andy Murray was defeated in the first round of the Paris Masters on Monday following a three-set battle with Dominik Koepfer.

Murray, given a wildcard entry, was initially drawn against Jenson Brooksby but the American withdrew just a couple of hours before the match was due to start because of an abdominal injury.

The three-time major singles champion instead faced German Koepfer, who triumphed 6-4 5-7 7-6 (11-9) in a contest lasting just over three hours.

Lucky loser Koepfer, in his debut in the main draw, served for the match at 5-3 in the second set but was broken to love as the contest turned topsy-turvy.

Murray had seven match points in the decider, including five in the tie-breaker, but the 2016 champion could not convert and left the court looking disconsolate.

"I was about to go back to the hotel and then one of the ATP Tour Managers texted me, 'Dom, you in? You're playing against Andy Murray'," Koepfer said. "Honestly, I was a little nervous.

"I didn't expect to play today, I was hoping that someone was going to pull out tomorrow. But a night match here in Paris, a lot of fans, they had an unbelievable crowd, the first time for me for a while. It's been a great day. Unexpected, but it worked out and I'm happy."

There was more disappointment for the United Kingdom as Dan Evans saw a strong start yield nothing as he lost in three sets to Alexander Bublik, who goes on to face sixth seed Casper Ruud.

Djokovic set for Fucsovics test

World number one Novak Djokovic will begin his campaign against Marton Fucsovics, who outlasted Fabio Fognini in a match lasing nearly two hours and 45 minutes.

Fucsovics dominated the first set but was engaged in a far tougher battle for the rest of the contest before winning 6-1 6-7 (6-8) 7-6 (7-5).

The Hungarian is 0-3 against Djokovic in his career, last losing to the 20-time major winner at the quarter-final stage of Wimbledon. The winner of this latest contest could face a last-16 meeting with Adrian Mannarino, who won in straight sets against Nikoloz Basilashvili.

Ilya Ivashka overcame Albert Ramos-Vinolas to secure a meeting with second seed Daniil Medvedev, while Dusan Lajovic will face Alexander Zverev after defeating Mackenzie McDonald.

Norrie brings up Tour century to keep Finals in sight

Tenth seed Cameron Norrie kept his chances alive of qualifying for the ATP Finals after a commanding 6-2 6-1 defeat of Federico Delbonis.

The Briton's victory, his 100th on the Tour, could help him to close the gap in the race for the year-ending tournament in Turin. Norrie started the week in 11th place, 140 points adrift of Jannik Sinner in the eighth and final automatic qualifying spot.

"It's obviously a great milestone and it shows I have been on the Tour and have a little bit of experience now," said Norrie. "It's a nice bonus, but there is a lot of tennis in the year to be played. It's a great achievement."

One man who will not qualify for the Finals is Aslan Karatsev. Last month's champion in Moscow lost in three sets to American Sebastian Korda, meaning he cannot now catch the top eight.

Novak Djokovic is unwilling to commit to January's Australian Open as the defending champion awaits confirmation on travel and entry requirements amid Victoria's vaccine mandate.

The state of Victoria, where the year's opening grand slam takes place at Melbourne Park, has introduced a vaccine mandate for professional athletes and across most industries due to the coronavirus pandemic.

The 2021 Australian Open went ahead, albeit in February instead of January, and without fans for most of the tournament following a snap lockdown of Melbourne due to COVID-19.

Last week, Australia prime minister Scott Morrison said unvaccinated players would be allowed to contest the slam if they completed two weeks in quarantine, though Victoria premier Dan Andrews dismissed those comments, insisting athletes would not be granted access unless they received the COVID-19 vaccine.

A record nine-time Australian Open champion, world number one Djokovic remains non-committal over his looming title defence.

"Well, I'm going to decide on whether I go to Australia or not after I see the official statement from Tennis Australia," Djokovic said as he prepares for the Paris Masters – his first tournament since losing to Daniil Medvedev in September's US Open final.

"Right now, we don't have any official announcement or statement. So until that's out, I won't be talking about this anymore, because I don't want to be part of the stories about the assumptions and what-ifs.

"When official condition requirements to travel to Australia and play in Australia are out, then obviously I'll see what I personally do with that, and also the bigger group of the players, you know, because the situation is obviously different in Australia than most parts of the world."

World number two Medvedev also refused to confirm his Australian Open participation.

"I always said it, that I really like Novak's answer about this. I want to keep my medical, no matter if it's about vaccine, leg injury, head injury... I want to keep my medical private for a reason," Medvedev said.

"I feel like tennis is such a brutal sport where you're always one on one against your opponent, and any information you give him can go against you.

"If you're playing Australia, it's obvious you're vaccinated. So that's why I said I'm willing to play Australia, but I won't say if you'll see me there, but we're going to see in January."

World number one Novak Djokovic said he will return to action at the Paris Masters blessed to be a more "humble" tennis player.

The Serbian makes his first appearance since his US Open final defeat to Daniil Medvedev at the ATP 1000 tournament in the French capital.

That defeat in New York cost Djokovic the chance to become only the third man to win a singles calendar slam by winning all four majors in the same year.

Djokovic also missed the opportunity to move top of the all-time Grand Slam tournament winners list and remains joint-top alongside Roger Federer and Rafael Nadal with 20 titles.

However, the 34-year-old – whose status for the 2021 Australian Open remains unknown – was phlegmatic when he reflected on his loss to Russian world number two Medvedev.

"In a most ideal scenario, I would have won all four of them," Djokovic told a media conference. "Knowing I was so close gives me great encouragement for the future, but it also makes me feel humble about my game, about my career.

"It gives me a kind of reality check where I have to go back to the practice court and really understand what needs to be done so that I could improve.

"This was not an ordinary loss considering the circumstances. I have learned over the years to deal with losses in such way that I treat them as great opportunities for growth.

"I feel that the US Open loss in the final has arrived arguably at the worst or at the best time for me, in a way.

"I'm disappointed that I lost the match, but I feel like I was blessed to experience love from the crowd and support from the stadium that I have never experienced before in my life in New York, and actually not in many places around the world.

"That kind of energy that I received from the crowd from the moment I stepped on the court until I stepped out is a win for life."

Djokovic, who has won four of the last eight Paris Masters tournaments, claimed the prospect of ending the year as the world number one ahead of Medvedev will motivate him.

Should he do so then Djokovic would leapfrog Pete Sampras for the most year-end number one finishes in history with seven.

He will face either Italian Fabio Fognini or Hungarian Marton Fucsovics having received a bye through the first round.

"The year-end number one is on the line between Medvedev and myself, and I'm in a pretty good position," added Djokovic, who has won 85 ATP tour titles.

"That's obviously the goal for the end of the season other than trying to do well in the Davis Cup with the national team. So hopefully I can have a strong finish of the season and clinch that year-end number one.

"I’m pleased to be back. I have been training really well the past couple of weeks. And I have had plenty of success in Paris over the years, so that gives me enough reason to believe that I can do well.

"The lack of match play could be dangerous, so I have to really make sure that I start off my first match very well with a good intensity and build my form."

Novak Djokovic's participation at the Australian Open has been cast in doubt once again as Victorian premier Daniel Andrews indicated the state that hosts the event will not welcome those who are not fully vaccinated against COVID-19.

Australian minister for immigration Alex Hawke revealed last week Djokovic, who has won a record nine titles at Melbourne Park, could only take part in January's tournament if he has received both jabs.

But the 20-time grand slam winner, who has declined to reveal his vaccination status, was given hope of competing after prime minister Scott Morrison said there would be exemptions should the state of Victoria – which includes Melbourne – agree.

However, responding to those comments on Wednesday, Andrews made clear his government would not apply for any sort of dispensation as it would not be fair on the other players and spectators who are fully vaccinated.

"The federal government manages the border and to the extent that anything the federal government says on this is clear, because their position has gone 180 from what the immigration minister said," Andrews said.

"What I'm making equally clear on behalf of every vaccinated Victorian who is doing the right thing... the only fair thing to do is to be very clear with every Victorian, my government will not be applying for an exemption for any unvaccinated player."

Recent reports suggested that over a third of professional players on the ATP Tour remain unvaccinated ahead of the 2022 Australian Open, which runs for two weeks from January 17.

Andrews added: "I'm not going to ask and actually require people sitting in the grandstand, people working at the event, to be vaccinated while players aren't.

"So we're not going to be applying for an exemption, so the issue is basically resolved."

Andrews also stated the same approach will be taken when Formula One returns to Melbourne in April next year.

Speaking last week, world number one Djokovic – who beat Daniil Medvedev earlier this year to win his latest Australian Open crown – told Serbian newspaper Blic: "Things being as they are, I still don't know if I will go to Melbourne.

"I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

"Of course I want to go, Australia is my most successful grand slam tournament. I want to compete, I love this sport and I am still motivated.

"I am following the situation regarding the Australian Open... I believe there will be a lot of restrictions just like this year, but I doubt there will be too many changes."

Australian Minister for Immigration Alex Hawke insists Novak Djokovic would need to be fully vaccinated against COVID-19 in order to enter the country and defend his Australian Open title.

The Serbian is the top-ranked player in the world and could move clear of Rafael Nadal and Roger Federer for grand slam titles if he can claim his 21st at Melbourne Park.

However, Hawke's comments regarding vaccination requirements cast doubts over Djokovic's participation, with the 34-year-old previously declining to reveal his vaccination status.

"You'll need to be double vaccinated to visit Australia," Hawke said to Australian Broadcasting Corporation radio. "That's a universal application, not just to tennis players. I mean that every visitor to Australia will need to be double vaccinated.

"I don't have a message to Novak. I have a message to everybody that wishes to visit Australia. He'll need to be double vaccinated."

With recent reports suggesting that over a third of professional players have yet to be fully vaccinated, a significant number could be denied the chance to play in the opening grand slam of 2022.

The men's ATP and women's WTA tours have attempted to encourage players with reservations to get the vaccine, and Tennis Australia explained that it was working with government authorities regarding conditions for the tournament.

"Our understanding is that the details around international visitors entering the country are yet to be decided and we hope to have more information soon," Tennis Australia said in a statement.

Australia's health minister Greg Hunt defended the ruling, explaining that the decision had been taken with the safety of the country's citizens in mind.

"The [rules] apply to everyone without fear or favour," Hunt said. "It doesn't matter whether you are number one in the world or you are anything else."

Djokovic, who withdrew from the Indian Wells Masters this month, has won nine of his majors at the Australian Open.

World number one Novak Djokovic is unsure if he will defend his Australian Open crown in Melbourne next year due to vaccination requirements.

The state of Victoria, where the year's opening grand slam takes place at Melbourne Park, has introduced a vaccine mandate for professional athletes and across most industries amid the coronavirus pandemic.

The 2021 Australian Open went ahead, albeit in February instead of January, and without fans for most of the tournament following a snap lockdown of Melbourne due to COVID-19.

Djokovic was among the players critical of the conditions athletes endured prior to this year's Australian Open, with strict quarantine measures introduced, though the nine-time champion cast doubt over his participation.

"Things being as they are, I still don't know if I will go to Melbourne," 20-time major winner Djokovic told Blic. "I will not reveal my status whether I have been vaccinated or not, it is a private matter and an inappropriate inquiry.

"People go too far these days in taking the liberty to ask questions and judge a person. Whatever you say 'yes, no, maybe, I am thinking about it', they will take advantage."

"Of course I want to go, Australia is my most successful grand slam tournament. I want to compete. I love this sport and I am still motivated," said Djokovic, who has not played since losing in the US Open final, having withdrew from the Indian Wells Masters.

"I am following the situation regarding the Australian Open and I understand the final decision [on COVID-related restrictions] will be made in two weeks. I believe there will be a lot of restrictions just like this year, but I doubt there will be too many changes.

"My manager, who is in contact with the Australian Tennis Federation, tells me they are trying to improve the conditions for everyone, both for those who have been vaccinated and those who have not."

Victoria state premier Daniel Andrews responded to Djokovic's comments on Tuesday, saying it was unlikely unvaccinated players would be granted a visa to travel to Australia.

"I don't think an unvaccinated tennis player is going to get a visa to come into this country and if they did get a visa they'd probably have to quarantine for a couple of weeks," Andrews told reporters.

Cameron Norrie became the first British player to win the ATP Indian Wells Masters after fighting back to beat Nikoloz Basilashvili in an historic three-set victory.

Norrie dropped the opening set before rallying to a memorable 3-6 6-4 6-1 triumph for the biggest title of his career on Sunday.

The world number 26 became the first man ranked outside the top 25 to win in the Californian desert since Ivan Ljubicic in 2010 as he moved 10th in the Race to Turin, with the ATP Finals taking place next month.

"It means so much to me, my biggest title. I'm so happy. I can't even describe it right now," 21st seed Norrie said in his on-court interview. "It was a strange match today but absolutely massive for me and my team.

"I can't really believe it. If you’d have told me I'd have won before the tournament started I wouldn’t have believed you, so it's amazing."

Basilashvili – the 29th seed – was down an early break at 3-1 before turning the first set on its ear by reeling off five straight games to seize control.

It was the first time Norrie had dropped an opening set at this year's tournament and it was looking ominous when the new British number one surrendered another break at 2-1 at the start of the second.

But a run of eight consecutive points fuelled Norrie, who broke to level the match against Basilashvili.

While Basilashvili had his chances, Norrie used his defensive skills to outlast the Georgian after almost two hours on court.

Norrie, who boasts a 47-20 record in 2021, added: "I've been really enjoying my tennis and been enjoying being out on court and competing in the big moments.

"I'm just really pleased with how I handled the occasion. I think I'm doing a lot better with that this year. I lost a lot of those finals, so it's nice to get the big one today."

ameron Norrie continued his sensational year by reaching his sixth and most significant final for the season with a straight-sets win over Grigor Dimitrov in the Indian Wells Masters semi-finals on Saturday.

The British 21st seed claimed his 46th win for the season, earning his sixth final appearance for the season, which is the equal most of any male player on tour, alongside Novak Djokovic.

Norrie will play Georgian 29th seed Nicoloz Basilashvili who defeated local Taylor Fritz in straight sets to reach a Masters 1000 final for the first time.

NORRIE TOPPLES TIRING DIMITROV

Norrie will also be making his maiden Masters 1000 final appearance after a 6-2 6-4 victory over 23rd seed Dimitrov in one hour and 26 minutes.

The 26-year-old Briton got ahead in both sets with an early break to set up the victory. Norrie moves ahead of Daniil Medvedev, Casper Ruud and Stefanos Tsitsipas and level with Djokovic for most final appearances this season.

"I've been playing a lot of big matches this year, which has helped," Norrie said during his on-court interview. "I feel like I am used to the big moments and the big matches.

"I'm feeling more and more comfortable and I feel like I am playing on my terms in key moments."

Dimitrov, who beat top seed Daniil Medvedev in an epic fourth round comeback, appeared spent physically with 31 unforced errors compared to Norrie's 19, with the Briton only hitting 12 winners for the match.

The triumph boosts Norrie's hopes of qualifying for the ATP Finals, with victory in the decider to see him move past Jannik Sinner into 10th position and within 125 points of the last position, currently occupied by Hubert Hurkacz.

BASILASHVILI MAKES MAIDEN MASTERS 1000 FINAL

Basilashvili overcame late nerves to secure his first-ever Masters 1000 final berth with victory over 31st seed Fritz in 7-6 (7-5) 6-3 in one hour and 41 minutes.

The 29-year-old, who had never won a main draw match at Indian Wells prior to this year's event, had 26-21 winners for the match, stepping up in the key moments to claim his breakthrough spot in a decider.

"It means a lot, especially at Indian Wells," Basilashvili said during his on-court interview. "People call this the fifth grand slam so it means a lot."

The Georgian was uncompromising and committed throughout, staving off three Fritz set points in the first set, before getting the lead in a tiebreak. Basilashvili converted his first break point for the match to lead 4-2 in the second set, although he spurned three match points with missed forehands, before sealing victory.

"For me, I'm first time experiencing semi-finals, finals and quarter-finals so I'm really tight," Basilashvili said. "It's natural but I try to get rid of it as much as I can. If I focus on my game and play, I can play good tennis."

Alexander Zverev rued a missed opportunity to win the Indian Wells Masters as he crashed out in the quarter-finals at the hands of home favourite Taylor Fritz.

American Fritz saved two match points to pull off an upset 4-6 6-4 7-6 (7-3) win over Olympic gold medallist Zverev.

Third seed Zverev was aware he had become hot favourite to triumph in California after Stefanos Tsitsipas crashed out to Nikoloz Basilashvili earlier on Friday, with US Open champion Daniil Medvedev already eliminated.

And the German was frustrated with his performance against Fritz, which left him unable to add to the Masters 1000 titles he has already won in Madrid and Cincinnati this year.

"It was just not really my day, to be honest," said Zverev, who had beaten Jenson Brooksby, Andy Murray and Gael Monfils to reach the last eight.

"I was close to winning, but the level of tennis was just not there for me.

"Mentally this is not easy for me. My next tournament is Vienna, so hoping I can deal with it well there, but right now I just want to go home.

"It was a very long season and I have played well but this one hurts because I knew that, after Stefanos lost this morning, I was kind of the favourite to win this tournament, but my tennis wasn't there yet."

Zverev had won 20 of his previous 21 matches on hard courts and led 5-2 in the deciding set.

But Fritz was not to be denied, firing 36 winners to secure the second top-five win of his career, with this triumph adding to impressive victories over Italian duo Matteo Berrettini and Jannik Sinner this week.

Fritz said: "This is the farthest I've ever been in a big tournament. 

"It is easily the best win of my life, against a really tough opponent on arguably the biggest match I could possibly play, so it's great.

"The biggest thing was match point down, I wanted to make him serve it out, so I just fought as hard as I could to hold that game.

"Then I got fortunate in his service game and from there I felt in control and felt really good under the pressure. I kept fighting. The crowd pushing me on meant so much.

"It is amazing. Especially the way that match ended with such high emotions with the crowd. The crowd was amazing and it is a dream come true."

Stefanos Tsitsipas and Alexander Zverev both crashed out in the quarter-finals on a day of upsets at the Indian Wells Masters.

Tsitsipas – the second seed – suffered a shock defeat to Nikoloz Basilashvili in a memorable outing for the Georgian in the Californian desert on Friday.

Afterwards, third seed Zverev was upstaged by Taylor Fritz in another boilover at the ATP Masters 1000 tournament.

BASILASHVILI BANISHES STEFANOS FOR MAIDEN MASTERS SF

In the biggest win of his career, 29th seed Basilashvili conquered French Open runner-up Tsitsipas 6-4 2-6 6-4.

Basilashvili's powerful groundstrokes from the baseline troubled Tsitsipas throughout as he reached his first Masters 1000 semi-final.

Prior to this year, Basilashvili had never won a main-draw match at Indian Wells in four previous appearances.

"I have played really great matches this tournament," said Basilashvili, who is the first Georgian in a Masters 1000 semi-final since Irakli Labadze in 2004. "I was not that happy with how I played today but I was happy with how I managed my stress levels.

"First time in the quarter-finals and it is a big court and Stefanos is a super tough player. I had to keep my physical levels and energy levels in a really good shape because I knew mentally I would be a little bit tight and stressed."

FRITZ SAVES MATCH POINTS TO UPSET ZVEREV

Next up for Basilashvili is 31st seed Fritz, who fended off two match points to surprise Olympic Games gold medallist Zverev 4-6 6-4 7-6 (7-3).

Fritz dropped the opening set and rallied from 5-2 down in the decider as he earned his second top-five victory of his career en route to his first Masters 1000 semi-final.

"I was really down and out but I found a way to put myself into it," Fritz said in his on-court interview. "I really wanted to make him have to close me out and I was able to get back into the match.

"Normally you would be so nervous in those situations and in the third set tie-break, but I felt so confident being aggressive, going after my game. It feels really great to play well with the pressure on."

It is the second Masters 1000 tournament of the season to feature three players in their first semi-final – Basilashvili, Fritz and Cameron Norrie – after the Miami Open.

Grigor Dimitrov continued his red-hot form with a hard-fought victory over Hubert Hurkacz at the Indian Wells Masters, where Cameron Norrie awaits in the semi-finals.

After conquering top seed Daniil Medvedev, former world number three Dimitrov recovered from a set down to upstage eighth seed Hurkacz on Thursday.

Norrie shocked 11th seed Diego Schwartzman in straight sets at the ATP 1000 tournament.

DIMITROV CELEBRATES MILESTONE

Bulgarian star and 23rd seed Dimitrov reached his first ATP Masters 1000 semi-final of the season with a 3-6 6-4 7-6 (7-2).

Dimitrov showed he is the comeback king once again, having also saved two break points at 3-3 in the second set.

A semi-finalist at the US Open (2019), Australian Open (2017) and Wimbledon (2014), Dimitrov then squandered a 5-2 lead in the deciding set before eventually prevailing in a tie-break for his 100th Masters 1000 victory.

NORRIE BOOSTS TURIN BID

Norrie's hopes of qualifying for the ATP Finals in Turin received a boost after breezing past Schwartzman 6-0 6-2.

Amid a career-best season, Norrie advanced to his maiden ATP Masters 1000 semi-final, with the 26-year-old to replace Daniel Evans as the new British men's number one.

Seeded 21st, Norrie – who has 45 Tour-level wins in 2021 – now has next month's Finals firmly in sight, having started the day 945 points behind ninth-placed Hurkacz in the race to Turin.

"I have been pretty consistent this year," Norrie said after 74 minutes on court. "I think I am really doing the fundamentals well on serve and return and playing the big points better.

"I have been a little more aggressive and feel I am learning more as I go along and becoming more experienced. We are really happy."
