Top seed Cameron Norrie is through to the semi-finals of the Delray Beach Open after beating Sebastian Korda in three sets.

Norrie eventually overcame the American fifth-seed after a final set tie-break, winning 6-2 1-6 7-6 (7-4).

The Brit's tenacity was key, saving seven of 10 break points, and he will now face another American, Tommy Paul, in the final four in Florida after he beat qualifier Stefan Kozlov 6-3 6-1.

The other semi-final will be contested between Reilly Opelka and John Millman after they bested Adrian Mannarino and Grigor Dimitrov respectively.

Opelka was taken to a third set by his French opponent before winning 7-6 (7-2) 3-6 6-1, hitting 19 aces on his way to victory.

Millan proved too good for third seed Dimitrov winning 6-4 6-4 in an hour and 34 minutes where the Australian's return was a highlight.

At the Rio Open, rain washed out many of the scheduled matches on Friday, with Diego Schwartzman against Pablo Andujar and Miomir Kecmanovic against Francisco Cerundolo both cancelled.

Matteo Berrettini and Thiago Monteiro were finally able to finish their round of 16 match at 11.35pm local time, with the Italian securing victory 6-4 6-7 (6-8) 6-3.

He will play seventh seed Carlos Alcaraz who overcame Federico Delbonis 6-4 7-6 (7-1) after their match was pushed back, starting not long prior to midnight local time.

Favourites Reilly Opelka and Grigor Dimitrov joined top seed Cameron Norrie in the quarter-finals of the Delray Beach Open after victories on Thursday.

With Norrie having already set up a quarter-final against last year's runner-up Sebastian Korda, the Briton was joined in the last eight by the second and third seeds. 

Grigor Dimitrov defeated Mitchell Krueger to mark his first appearance since a disappointing second-round exit at the Australian Open in style.

The Bulgarian won 7-6 (7-4) 6-3, with Serena and Venus Williams watching on from the crowd in far from ideal conditions in Florida.

"It's always very tough [in your opening match], especially playing the last match on," Dimitrov said.

"I've been here for a week already and I was eager to get out there and play. Today was just a match I had to get through. Very tough conditions: rain, wind, cold, hot. It is what it is, and you've got to deal with it."

Opelka, who won the tournament in 2020, went the distance against fellow American Jack Sock, eventually prevailing 6-7 (6-8) 7-6 (7-4) 6-1. 

He will face Adrian Mannarino in the last eight, after the Frenchman's 6-4 2-6 7-5 defeat of Brandon Nakashima. Dimitrov will play Australian John Millman.

At the Rio Open, only two of the four scheduled matches were completed due to rain.

Qualifier Miomir Kecmanovic dispatched sixth seed Lorenzo Sonego 7-5 6-4, while Francisco Cerundolo overcame Roberto Carballes Baena.

Top seed Matteo Berrettini's clash with Brazilian Thiago Monteiro was pushed back to Friday, while Carlos Alcaraz will resume his match against Federico Delbonis in a strong position in the first set.

Diego Schwartzman felt he played "an almost perfect match" to overcome Pedro Martinez in straight sets and reach the quarter-finals of the Rio Open.

The third seed advanced with a 6-1 6-1 victory, though that does not quite tell the whole story as the second game of the first set lasted a mammoth 24 minutes and 40 seconds.

Martinez saved eight break points in that lengthy game before finally being outdone by Schwartzman, who will now face another Spaniard in Pablo Andujar.

Incredibly, Martinez won 31 points in the first set but just one game.

"It was unbelievable," Schwartzman said. "This was probably the longest game in the history of the tournament 

"I don't remember anything like this before. I played an almost perfect match, I played against an opponent that had as much confidence as me."

Andujar beat Albert Ramos-Vinolas 7-5 5-7 6-3, while fourth seed Pablo Carreno-Busta lost 5-7 6-4 6-3 to Fabio Fognini in the shock of the day.

Federico Coria awaits Fognini after following up his surprise win over defending champion Cristian Garin with a 7-6 (7-2) 4-6 6-4 victory against Fernando Verdasco.

At the Delray Beach Open, top seed Cameron Norrie beat Oscar Otte 6-3 7-5 and will face Sebastian Korda, who saw off Andreas Seppi 7-5 6-3, for a place in the semi-finals.

Tommy Paul and Stefan Kozlov are also through to the final eight in Florida after beating Denis Istomin and Steve Johnson respectively in straight sets.

Stefanos Tsitsipas' impressive display of power hitting helped him past Alex De Minaur and into the semi-finals of the Rotterdam Open.

The Greek has yet to win an ATP 500 tournament but is now a step closer to ending that record after overcoming his Australian opponent 6-4 6-4 in a little over 90 minutes.

De Minaur's excellent movement was quelled by Tsitsipas, who hit 19 winners and won 27 of 33 first-serve points (82 per cent).

Speaking after his win, Tsitsipas said: "I took my time, I tried to understand what works for me and what doesn't, and with the right momentum, with the right intention, things kind of paid off. 

"I was able to get ahead in the score, which gave me a lot of confidence, and I think my serve was very good today, it gave me a lot of points and applied a lot of pressure to him."

Czech qualifier Jiri Lehecka is Tsitsipas' surprise semi-final opponent as the world number 137 continued a fine run by defeating Lorenzo Musetti 6-3 1-6 7-5.

There was a sense of deja vu in the later sessions as Andrey Rublev defeated Marton Fucsovics 6-4 6-3.

Rublev defeated the same opponent in the final of the 2021 tournament, and is now one win away from returning to the showpiece match.

Felix Auger-Aliassime is backing up a strong performance at the Australian Open, where the world number nine was beaten by Daniil Medvedev in the quarter-finals.

The Canadian came through a tough encounter against Cameron Norrie 7-5 7-6 (7-4) as he aims to go one better than his runners-up appearance in Rotterdam in 2020.

Andy Murray suffered defeat in the second round of the Rotterdam Open as he fell in straight sets to Felix Auger-Aliassime, while Andrey Rublev and Stefanos Tsitsipas progressed. 

Murray, who triumphed at this tournament in 2009, battled past Alexander Bublik in his opening match but struggled to replicate that form against Auger-Aliassime on Thursday. 

The Scot was never in control against the world number nine, who will face Murray's fellow Briton Cameron Norrie in the quarter-final, as he was downed 6-3 6-4 by the third seed. 

"From the start of the match I was ready and focused and I think that is why I was able to produce a high level from the first point," Auger-Aliassime said on court after his victory.  

"He made me bring out my best tennis and I am really happy with the way I played and that I was able to stay ahead. [To] win in straight sets is a great relief." 

Top seed Tsitsipas, who was a beaten semi-finalist in this event last year, made light work of Ilya Ivashka as he raced to a 6-4 6-1 triumph in just one hour and 11 minutes to tee up a last-eight meeting with Alex de Minaur. 

Reigning champion Rublev cruised past Soonwoo Kwon in similar fashion with a 6-3 6-3 win to secure his seventh straight victory at the ATP 500 tournament. 

Meanwhile, qualifier Jiri Lehecka recovered from a first-set scare against Botic van de Zandschulp to succeed 1-6 6-4 6-4, with Lorenzo Musetti awaiting the Czech in the next round. 

Hubert Hurkacz bounced back from a disappointing Australian Open campaign with a straight-sets win over Jo-Wilfried Tsonga at the ABN AMRO World Tennis Tournament in Rotterdam.

Fourth seed Hurkacz, who was beaten in the second round in Melbourne by Adrian Mannarino, saw off wildcard Tsonga 6-4 7-6 (9-7) in one hour and 32 minutes.

"Jo is an amazing player and competitor," Hurkacz said of the former world number five.

"He brought a really high level and it was a really tough match for me and he is definitely on the way back.

"Jo has achieved so much in his career and playing against him you can see why with his shots and his serve. I appreciated playing him and I am happy with the win today."

World number 11 Hurkacz will face either Lorenzo Musetti or Mikael Ymer in the second round.

Sixth seed Cameron Norrie overcame Ugo Humbert 6-2 6-4, while eighth seed Nikoloz Basilashvili was dumped out by American Mackenzie McDonald 6-3 6-2.

McDonald will face Alex de Minaur in the next round after the Australian swatted aside David Goffin 6-0 6-3.

"I think I played really well," De Minaur said. "I played exactly how I wanted to. My coach and I set up a plan about how we wanted to play this match and I managed to execute it.

"It is a very good feeling. Mentally I thought I was very solid and positive and that is one of the main aspects I am trying to focus on this year."

Novak Djokovic made it three wins from three at the ATP Finals as he eased past Cameron Norrie in just over an hour in Turin.

The Serbian had already won the Green Group before this dead rubber but maintained an exceptional level to beat Norrie 6-2 6-1 in the first ever meeting between the two.

It was already confirmed beforehand that Djokovic will face Alexander Zverev in the semi-finals on Saturday, and he began as he meant to go on here by breaking the Brit in the first game of the match, before doing so again in the fifth as he strolled to the first set in just 28 minutes.

Norrie – who was an injury-replacement for Stefanos Tsitsipas – showed some of the grit and skill that earned him a spot as second replacement for the season-ending tournament but struggled to keep up with the world number one.

Djokovic broke immediately again in the second set, though was forced to save a break point in the next game as his opponent tried to revive the match.

Norrie only managed to get 57 per cent of first serves in, and only won 52 per cent of those, compared to Djokovic who won 81 per cent of his first-serve points.

The 26-year-old was broken again in the fifth game of the second set, before a third break in the seventh secured Djokovic his third straight-sets win in a row at the Finals.

Casper Ruud fought back from a set down to claim his maiden ATP Finals victory after late replacement Cameron Norrie made a blistering start in Turin.

Norrie stepped in as a second alternate at the season-ending event at the Pala Alpitour following Stefanos Tsitsipas' withdrawal due to an elbow injury on Wednesday.

The Briton got off to a flyer in his first ATP Finals match, but eighth seed Ruud hit back to win 1-6 6-3 6-4 in the night session after losing his opening Green Group contest to world number one Novak Djokovic.

Ruud lost only two games when the two met in the San Diego Open final last month and Norrie looked hungry for revenge as he bossed the first set, grasping both break-point opportunities.

Ruud won the only break point of the second set to force a decider and just one further break was enough to get him up and running in the competition.

After becoming the first Norwegian to win an ATP Finals match, Ruud will do battle with Andrey Rublev to join Djokovic in qualifying from the group.

Ruud  – 32/22

Stefanos Tsitsipas has been forced to withdraw from the ATP Finals in Turin because of an injury to his right elbow, with Cameron Norrie taking his place.

Tsitsipas was beaten in straight sets by Andrey Rublev - who faces Novak Djokovic next - in his opening Green Group match on Monday and was scheduled to take on Casper Ruud on Wednesday.

However, the 23-year-old's elbow issue means that ATP Finals debutant and Indian Wells winner Norrie will play Ruud instead, in his first match of the group stage.

Ruud's first outing ended in a straight-sets defeat at the hands of Djokovic, although the Norwegian may be more confident of his chances in this match, having beaten Norrie 6-0 6-2 in their only other encounter last month at the San Diego Open final.

Tsitsipas - who won the ATP Finals in 2019 - was forced to retire from his Paris Masters clash against Alexei Popyrin last month, also due to an ongoing elbow problem, and the Greek is no longer able to play through the pain.

Norrie is the second alternate to join the competition after an injury to one of the original eight. Jannik Sinner replaced fellow Italian Matteo Berrettini and went on to defeat Hubert Hurkacz in the Red Group on Tuesday.

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.

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."

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."

Daniil Medvedev was ousted from the Indian Wells Masters, the US Open champion and top seed stunned by former world number three Grigor Dimitrov in a thrilling comeback.

Dimitrov had been a set and a double break down against the Russian star on Wednesday, before launching a remarkable rally for his first win over a top-two opponent since 2016.

Meanwhile, second seed Stefanos Tsitsipas and third seed Alexander Zverev both won to secure their spots in the last eight.

MEDVEDEV SHOCKED IN THE DESERT

Dimitrov roared back to triumph 4-6 6-4 6-3 over Medvedev, who had won 18 of his past 19 matches on North American soil.

Bulgarian star Dimitrov trailed 4-1 in the second set after dropping the opener before stunning the first-time grand slam champion midweek.

"I just felt something at 1-4 and I calmed myself down and started to take better decisions and started to control the pace of the game, which I really believed helped me," Dimitrov – the 23rd seed – said. "In the end it was just very solid and smart play."

Dimitrov finished the match with 25 winners, while he was also excellent at the net, helping him claim his first quarter-final appearance at an ATP Masters 1000 event this season.

Medvedev sent down 5-1 aces but only managed a 54 per cent first-serve percentage, while he also faced 10 break points across the match. Dimitrov won five games in a row to claim the second set.

"I don't remember myself losing three service games, even four service games ever, I guess, on hard courts," Medvedev said.

"That shows how slow this court is and the conditions, more like clay, I would say, which I don't like, because to lose serve four times is just unacceptable."

Dimitrov will face eighth seed Hubert Hurkacz in the quarter-finals after he got past Australian Open semi-finalist Aslan Karatsev 6-1 6-3.

Medvedev added: "Grigor played [the] second part of the match better than anybody did against me [at the] US Open that I won. Playing this level, I don't see him losing to anybody, but let's see the result."

ZVEREV MAKES STATEMENT WITH MONFILS WIN

Olympic Games gold medallist Zverev bulldozed his way past 14th seed Gael Monfils 6-1-6-3 en route to the last eight.

German star Zverev claimed his 20th win from his last 21 matches, needing just over an hour to dispatch Monfils.

Zverev claimed 19 of 25 points at the net, hitting 19 winners including 11 with his forehand, while converting four of eight break points.

"I felt well on the court today. Gael is someone I haven't beaten before, so I knew had to play my best tennis and I definitely was not far away," Zverev said during his on-court interview.

Zverev will take on American 31st seed Taylor Fritz, who defeated 10th seed Jannik Sinner 6-4 6-3.

TSITSIPAS OUTLASTS DE MINAUR

French Open runner-up Tsitsipas saw off a tough challenge from Australian Alex de Minaur to secure his spot in the quarter-finals 6-7 (3-7) 7-6 (7-3) 6-2.

Tsitsipas fought back from a set down to win against the 22nd seed, triumphing in two hours, 43 minutes.

Greek star Tsitsipas showed grit to outlast the tiring De Minaur and will face 29th seed Nikoloz Basilashvili after he knocked off fellow seed Karen Khachanov 6-4 7-6 (8-6).

"That was incredible the way I just stayed in the match," Tsitsipas said. "I had to go through so many difficulties in order to find a solution and I executed towards the end of the match."

There were further top-10 casualties, with sixth seed Casper Ruud also bowing out 6-3 6-3 to 11th seed Diego Schwartzman, who will meet Cameron Norrie in the quarters.

Top-10 seeds Andrey Rublev and Denis Shapovalov were bounced from the Indian Wells Masters on Monday as number one seed Daniil Medvedev hit a season milestone. 

Tommy Paul took down Rublev, beating the fourth seed for the first time in four meetings, while the ninth-seeded Shapovalov fell to Aslan Karatsev.

The news was not all bad for the higher seeds, though, as US Open champion Medvedev picked up his 50th win of the year. 

PAUL DOWNS RUBLEV

Playing in the main draw at Indian Wells for the first time, the 24-year-old American Paul outlasted Rublev 6-4 3-6 7-5 for his second win in eight career matches against top-10 players.

Paul was on the offensive throughout the match, firing 41 winners while making 37 unforced errors, while Rublev had 23 of each. 

The Russian will lament missed opportunities, as he converted just four of 14 break point chances before watching Paul break him twice in the final set to prevail. 

Paul moves on to face 21st seed Cameron Norrie, who beat Roberto Bautista Agut 6-4 5-7 6-3.

MEDVEDEV NOTCHES 50TH WIN

Medvedev had to work a bit to get past 27th seed Filip Krajinovic 6-2 7-6 (7-1), improving to 38-5 on hard courts in 2021. Only Stefanos Tsitsipas (52) has more victories overall this year. 

The Russian had 25 winners and 18 unforced errors while winning 70 per cent of points on his first serve. 

He next faces 23rd seed Grigor Dimitrov, who downed 16th seed Reilly Opelka 6-3 6-4. 

KARATSEV UPSETS SHAPOVALOV

Playing at Indian Wells for the first time, 19th seed Karatsev upset Shapovalov 7-5 6-2, saving the only break point he faced in the match.

Casper Ruud, seeded sixth, rallied past Lloyd Harris 6-7 (4-7) 6-4 6-4 as he seeks his sixth tournament title this year. 

He will face 11th seed Diego Schwartzmann, who beat 18th seed Daniel Evans 5-7 6-4 6-0 to reach the fourth round at Indian Wells for the first time.

Eighth seed Hubert Hurkacz had little trouble with Frances Tiafoe, rolling past the American in straight sets.

Jannik Sinner, the 10th seed, advanced via walkover when John Isner withdrew from the tournament to fly home and be with his wife Madison with their third child expected to arrive ahead of schedule on Tuesday.
