Daniil Medvedev and Stefanos Tsitsipas progressed to the third round of the Madrid Open but there was no such luck for Felix Auger-Aliassime on Saturday.

Second seed Medvedev cruised past Italian qualifier Andrea Vavassori 6-4 6-3, teeing up a meeting with Alexander Shevchenko, who overcame Jiri Lehecka in straight sets.

Tsitsipas was made to work by Dominic Thiem, but the fourth seed battling from a set down to win 3-6 6-1 7-6 (7-5).

World number 40 Dusan Lajovic provided the shock of the day by defeating seventh seed Auger-Aliassime 6-2 3-6 7-6 (7-5).

Denis Shapovalov, the 21st seed, was another surprise second-round loser, falling 6-7 (4-7) 6-4 7-6 (7-1) to China's Zhang Zhizhen.

Taylor Fritz avoided adding to the list of notable early eliminations in the Spanish capital, the eighth seed battling to a 7-6 (13-11) 6-4 victory over Christopher O'Connell.

Fritz's fellow American Frances Tiafoe progressed with a 6-3 7-6 (7-5) triumph over Argentina's Tomas Martin Etcheverry, while 14th seed Tommy Paul crashed out after a 6-3 7-6 (7-3) defeat to Roman Safiullin.

Seeds Alex de Minaur and Sebastian Baez also navigated their way through to the third round, defeating Marco Cecchinato and Marcos Giron respectively, as did Cameron Norrie at the expense of Yosuke Watanuki.

Carlos Alcaraz raced through to the Barcelona Open final as the defending champion set up a final showdown with Stefanos Tsitsipas.

With his 20th birthday approaching on May 5, world number two Alcaraz will have the chance on Sunday to land his ninth ATP title as a teenager.

Alcaraz crushed the hopes of first-time Barcelona semi-finalist Dan Evans, racing to a 6-2 6-2 victory over a player who was seeking to become the first British finalist at this tournament.

Earlier, Tsitsipas, who had not dropped serve en route to the semi-finals, had to dig deep for a 6-4 5-7 6-3 victory against Lorenzo Musetti, the Italian who beat Novak Djokovic in Monte Carlo last week.

Greek star Tsitsipas bizarrely has a 0-9 record in finals at ATP 500 level, the tier at which this tournament sits, despite having won two of his six title matches in elite ATP 1000 events.

Alcaraz will start as a firm favourite in the final. He holds a 3-0 career head-to-head lead over Tsitsipas from their past meetings, including a three-set win in the Barcelona quarter-finals last year.

That was a stormy encounter, with Alcaraz taking exception to almost being hit by a shot from Tsitsipas at the end of the opening set, so the rematch could be one to savour.

"It's so special to play a final here in Barcelona, a tournament I love playing," Alcaraz said on Prime Video. "I came to watch this tournament when I was very, very young, and I played for this club when I was 12, 11. I love this club, I love this tournament, and it's so special to have the chance to lift the trophy here again.

"Last year [against Tsitsipas] we had a spicy match, but I know he's a really nice guy off the court."

At the BMW Open in Munich, it was much the same story on Saturday.

Defending champion Holger Rune, another 19-year-old with a birthday approaching, in his case on April 29, earned another shot at the title.

Rune set up a Sunday showdown against Botic van de Zandschulp, in what will be a repeat of last year's final.

A resilient Rune lived up to his top seeding by ending Christopher O'Connell's fine run, which included a win against Alexander Zverev at the last-16 stage.

The 6-3 6-2 outcome masked the fact Rune saved eight break points as unseeded world number 82 O'Connell threatened to make it a tighter contest on the scoreboard than it turned out to be.

Van de Zandschulp then scored a fine win in the second semi-final as the Dutch fourth seed got the better of American second seed Taylor Fritz, winning 6-4 7-6 (7-2) 

Last year's trophy match ended in disappointment when Van de Zandschulp retired due to chest pains during the first set, with Rune saying it was "probably the worst way to win a final".

Rune has three ATP titles to his name, with 27-year-old Van de Zandschulp yet to lift a singles trophy.

Carlos Alcaraz kept his Barcelona Open title defence on track following a 7-6 (7-5) 6-4 victory over compatriot Alejandro Davidovich Fokina in the quarter-finals.

The world number two is aiming to become the first player to successfully defend the Barcelona crown since Rafael Nadal won three in a row between 2016 and 2018.

And though run close by Davidovich Fokina, the reigning champion has now reeled off six sets without reply, taking his overall record at the ATP 500 event to 8-1.

The Spaniard, who is now 9-1 against his fellow countrymen since the start of 2022, will play Dan Evans in the last four. The Briton came from behind to defeat 15th seed Francisco Cerundolo 2-6 7-5 6-3.

They are joined by Stefanos Tsitsipas, whose quest for a first title of the campaign continues after a commanding 6-4 6-2 victory over eighth seed Alex De Minaur.

The second seed, who was runner-up at this event in 2018 and 2021, sealed the deal in one hour and 21 minutes to claim his ninth successive win against the Australian.

His reward is a showdown with Lorenzo Musetti, who received a walkover into the last four following Jannik Sinner's withdrawal.

Over in Munich, reigning champion Holger Rune booked his semi-final place with a dominant 6-2 6-4 win over Cristian Garin.

The world number seven, who is now 7-0 in this event, will play Christopher O'Connell. After defeating Alexander Zverev earlier in the week, the Australian qualifier built on his momentum by seeing off Flavio Cobolli 7-6 (7-5) 4-6 6-3.

Second seed Taylor Fritz also advanced in straight sets with a 6-3 6-4 victory over former world number three Dominic Thiem, who overcame eighth seed Marc-Andrea Huesler earlier in the day.

Fritz's semi-final opponent will be Botic van de Zandschulp after the fourth seed saw off Marcos Giron 7-6 (7-5) 6-3.

Defending champion Stefanos Tsitsipas and Daniil Medvedev were both dumped out at the quarter-final stage of the Monte Carlo Masters, with Taylor Fritz and Holger Rune advancing.

Seeded second and third respectively, Tsitsipas and Medvedev began Friday as the tournament's highest-ranked players following Novak Djokovic's shock exit, but both found themselves on the receiving end of comprehensive defeats.

World number three Tsitsipas was the victim as Fritz claimed his first victory over a top-10 ranked player on clay, ending the Greek's 12-match winning run at the competition with a 6-2 6-4 success.

Tsitsipas – who won the event in both 2021 and 2022 – was unable to contain Fritz as the American hit a series of huge winners en route to his third Masters 1000 semi-final.

Fritz will face Andrey Rublev in the final four after the fifth seed saw off the challenge of German qualifier Jan-Lennard Struff, posting a 6-1 7-6 (7-5) win.

Meanwhile, Medvedev came up short in his tussle with Rune, as the 19-year-old waltzed into his second Masters 1000 semi-final with a 6-3 6-4 triumph.

"It wasn't easy for sure, it's always tough to play Daniil," Rune said after his win. "It was actually my first time playing against him in a real match, but we've practised tonnes of times. 

"I have huge respect for everything he's done. In the last week it was not easy to stop him, but I'm happy I managed to do it."

Rune now has a 10-8 record in meetings with his fellow top-10 players, and he will have to win another such duel to make the final, with Jannik Sinner his semi-final opponent.

Sinner needed 76 minutes to beat fellow Italian Lorenzo Musetti 6-2 6-2, and the 21-year-old now has the chance to reach his third Masters 1000 final, having previously finished as runner-up at two editions of the Miami Open.

World number one Carlos Alcaraz made it 10 wins in a row in Miami and kept alive his hopes of a rare Sunshine Double as he beat Taylor Fritz in straight sets in Thursday's quarter-finals.

Alcaraz swept aside the 2022 Indian Wells champion 6-4 6-2 in a lopsided Miami Open contest which lasted only 79 minutes, with the Spaniard breaking Fritz in the opening game of both sets.

Both players hit 20 winners, including 11 each on their respective forehands, but Fritz almost doubled Alcaraz' unforced errors count (28-13).

The 19-year-old was impressive from the baseline and overwhelmed Fritz in the end. The American only won 38 per cent on his second serve.

Alcaraz, who won the Indian Wells title a fortnight ago, remains on track to become the eighth male to win the Sunshine Double (Indian Wells and Miami), with Roger Federer the last to achieve that in 2017.

The Spaniard would join Federer (2005, 2006, 2017), Novak Djokovic (2011, 2014, 2015, 2016), Andre Agassi (2001), Marcelo Rios (1998), Pete Sampras (1994), Michael Chang (1992) and Jim Courier (1991) in achieving the Sunshine Double.

Alcaraz will take on Italian 10th seed Jannik Sinner in the semi-finals, after the duo faced off in the Indian Wells last four a fortnight ago, with the Spaniard winning in straight sets.

In-form Daniil Medvedev progressed to the semi-finals with a 6-3 7-5 victory over American qualifier Chrstopher Eubanks, who had enjoyed a dream run in Miami.

Medvedev has a 27-3 record this season and will pursue a fifth straight ATP Tour final when he takes on compatriot Karen Khachanov in the semi-finals.

Khachanov, who made this year's Australian Open semi-finals, defeated Francisco Cerundolo 6-3 6-2 in 76 minutes.

Second seed Stefanos Tsitsipas was bundled out of the Miami Open in straight sets during Tuesday's fourth round by 2022 US Open semi-finalist Karen Khachanov.

The Russian 14th seed prevailed 7-6 (7-4) 6-4 over Tsitsipas in one hour and 34 minutes, powering 25 winners and making only nine unforced errors, compared to the Greek's 14.

Khachanov's triumph ended a winless 0-6 head-to-head record against Tsitsipas, while it also snapped his own 23-match losing streak against top-10 opponents.

The Russian, who also made this year's Australian Open semi-finals, has qualified for four of his six tour-level events this year.

Khachanov will take on 25th seed Francisco Cerundolo in the quarter-finals, with the Argentinian fighting back to get past Lorenzo Sonego 3-6 6-3 6-2 in just over two hours.

Defending champion and top seed Carlos Alcaraz had less trouble against Tommy Paul, cruising into the quarter-finals with a 6-4 6-4 victory.

Alcaraz won the winners' count 24-9, setting up a quarter-final clash with ninth seed Taylor Fritz, as the Spanish 19-year-old chases a rare Sunshine Double, having won last week's Indian Wells Open.

Fritz progressed after getting past seventh seed Holger Rune 6-3 6-4 in 86 minutes, sending down eight aces and 22 winners for the match.

Fourth seed Daniil Medvedev played late into the evening after a lengthy rain delay in Miami, but made light work of Quinten Halys 6-4 6-2, triumphing just past 1:30am local time.

Medvedev, who is into his third straight Miami quarter-final, will face American qualifier Christopher Eubanks in the last eight after he got past Frenchman Adrian Mannarino 7-6 (7-2) 7-6 (7-5) in another rain-delayed contest.

Italian 10th seed Jannik Sinner knocked off sixth seed Andrey Rublev 6-2 6-4, advancing to face Emil Ruusuvuori after he beat Botic van de Zandschulp 4-6 6-4 7-5.

Top seed and reigning champion Carlos Alcaraz dished out a bagel as he continued his outstanding form with a straight-sets victory over Dusan Lajovic to ease into the Miami Open fourth round on Sunday.

Alcaraz, who triumphed at last week's Indian Wells Open, beat the 76th-ranked Serbian 6-0 7-6 (7-5) in one hour and 32 minutes.

The 19-year-old Spaniard hit 26 winners compared to Lajovic's eight, while Alcaraz also sent down three aces on a 75 per cent first serve percentage.

Alcaraz won the first frame to love in 32 minutes, registering his fourth career bagel at ATP Masters 1000 level, equaling the most by a teenager alongside Rafael Nadal.

The world number one will face 2023 Australian Open semi-finalist Tommy Paul in the fourth round after the American got past 20th seed Alejandro Davidovich Fokina 6-3 7-5.

Third seed and 2022 Miami Open finalist Casper Ruud blew a first-set lead to lose 3-6 6-4 6-4 to Botic Van De Zandschulp.

The Dutchman improved his head-to-head record against Ruud to 3-1 with his first-ever top five win, with the Norwegian left to lament converting only two of 15 break points.

Ninth seed Taylor Fritz progressed into the fourth round with a 6-4 6-4 win over Denis Shapovalov, improving his head-to-head record against the Canadian to 4-5. Fritz committed only eight unforced errors and did not face one break point.

Jannik Sinner maintained his excellent hard-court form with his 18th win this season on the surface, as he defeated Grigor Dimitrov 6-3 6-4 in one hour and 28 minutes. The Italian 10th seed will be Andrey Rublev in the next round.

Sixth seed Rublev needed less than an hour to get past Miomir Kecmanovic 6-1 6-2, while compatriot Daniil Medvedev advanced via a walkover against Alex Molcan due to a right hip injury.

Seventh seed Holger Rune cruised past Diego Schwartzman 6-4 6-2, while Finland's Emil Ruusuvuori got past Taro Daniel 6-3 7-6 (7-3).

World number one Carlos Alcaraz wasted no time in advancing to the Miami Open third round with a straight-sets win over Facundo Bagnis in just 64 minutes, while 13th seed Alexander Zverev suffered an early exit on Friday.

Reigning US Open champion Alcaraz eased past Bagnis 6-0 6-2, firing 12 winners and three aces for the match, committing only 11 unforced errors.

The Spaniard won the first set in 24 minutes, marking the first time he has won an opening frame 6-0 at an ATP Masters 100 event. It was also the first bagel he has dished out since beating Bagnis in Umag last year.

"I knew that I needed to be focused for my first match," Alcaraz said after his win, having triumphed in Indian Wells last week. "To start a new tournament is never easy, different conditions.

"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning, and I'm happy with the way that I played. I try to improve every day."

Alcaraz will face Dusan Lajovic after he beat 30th seed Maxime Cressy 6-4 7-6 (7-2), having knocked off Andy Murray in the first round.

Zverev was the highest seed to bow out on Friday, going down 6-0 6-4 to Japan's Taro Daniel, who beat world number four Casper Ruud last month in Acapulco.

Daniel triumphed in 73 minutes against the German, hitting 17 winners and committing only two unforced errors for the match, while Zverev gave up 18.

The Japanese wild card will meet Emil Ruusuvuori in the third round after the Finn beat 22nd seed Roberto Bautista Agut 6-4 7-6 (7-5) to open up that section of the draw.

Third seed Ruud also had few problems getting past Ilya Ivashka 6-2 6-3 to set up a clash with Botic van de Zandschulp after his three-set win over Alexei Popyrin.

Sixth seed Andrey Rublev overcame J.J. Wolf 7-6 (7-3) 6-4, having been broken in the opening game of what was a tight contest.

Jannik Sinner beat Laslo Djere 6-4 6-2, marking his 16th win out of 20 appearances at the Sunshine Double (Indian Wells and Miami), with only three other players – Novak Djokovic, Alcaraz and Hubert Hurkacz – having as many wins within their first 20 matches.

Ninth seed Taylor Fritz defeated fellow American Emilio Nava 6-4 6-1, and will face Denis Shapovalov in round three after he beat Guido Pella 6-3 3-6 6-3.

American 16th seed Tommy Paul came from a set down to beat Marc-Andrea Huesler 5-7 6-3 6-4, while seventh seed Holger Rune beat Martin Fucsovics 6-3 7-5.

Rafael Nadal has dropped out of the world's top 10 men's tennis rankings for the first time in almost 18 years.

Nadal has been in the top 10 ever since April 2005, but on Monday fell to 13th in the ATP rankings after injury forced him to miss Indian Wells.

The 36-year-old's run came to an end on the same day that teenage compatriot Carlos Alcaraz reclaimed his number one spot from Novak Djokovic after beating Daniil Medvedev in Sunday's Indian Wells final.

Nadal is yet to recover from the hip injury that has hampered him since his Australian Open exit to Mackenzie McDonald in January.

Though the 22-time grand slam winner could return to the top 10 once he is back in action, it will not be in the next month as he has also withdrawn from the Miami Masters.

The latest ATP rankings saw Djokovic drop to second place, while Medvedev moved from sixth to fifth, Felix Auger-Aliassime leapt from 10th to sixth, Hubert Hurkacz nudged into the top 10 as he moved up two places to ninth, while Taylor Fritz dropped from fifth to 10th.

World number two Carlos Alcaraz is through to the Indian Wells Open semi-final after defeating 11th seed Felix Auger-Aliassime 6-4 6-4 on Thursday.

Alcaraz, 19, continued his terrific start to 2023, now boasting 12 wins from his first 13 matches of the year after winning the Argentina Open and reaching the Rio Open final.

But despite the Spaniard's status as the game's top young talent, he came into the contest winless in his three previous meetings against Canada's Auger-Aliassime.

What separated the two this time around was Alcaraz's ability to keep the ball in play. He produced 26 winners with only eight unforced errors, and while Auger-Aliassime was not much worse (24 winners, 13 unforced errors), he committed six double faults.

He is now one match away from reaching the third Masters 1000 final of his career, having won both the Miami Open and the Madrid Open this past season.

Meeting him in the semi-final will be Italy's Jannik Sinner after he prevailed 6-4 4-6 6-4 against hometown hero Taylor Fritz.

In the seesawing contest, Sinner narrowly edged the total point count 94-86 – with both committing exactly 17 unforced errors – but the Italian created nine break point chances compared to Fritz's three.

Since the beginning of the Australian Open, Sinner sports a 14-2 record, with the only losses in that span coming against world number three Stefanos Tsitsipas and world number six Daniil Medvedev.

It will be the sixth meeting between Sinner and Alcaraz, with the Spanish teen taking in a 3-2 edge after a five-set thriller at the US Open.

Top seed Carlos Alcaraz moved into the Indian Wells Open quarter-finals after Jack Draper retired down 6-2 2-0 due to an abdominal injury in their last-16 clash on Tuesday.

Alcaraz was in control, winning the first set in 36 minutes before racing to a 2-0 lead inside 10 minutes before the Briton withdrew. Draper had battled the injury in the latter stages of Monday's win over Andy Murray.

Despite that, the Spaniard looked in good touch, setting up a quarter-final meeting with eighth seed Felix Auger-Aliassime, who has a 3-0 head-to-head record against him.

"I felt the ball really well. I'm really happy with that part," Alcaraz said. "I would say I returned well, I hit great shots. I finished the match with confidence in my shots, to come into the next round with more confidence."

Auger-Aliassime saved six match points in a dramatic triumph over 17th seed Tommy Paul to reach the last eight, winning 3-6 6-3 7-6 (8-6) in two hours and 48 minutes.

The Canadian trailed 0-40 on serve at 5-6 in the deciding set before winning the next five points. He repeated that feat, down 3-6 in the tie-break, capitalising on his first match point. Auger-Aliassime hit 31 winners for the match, along with 51 unforced errors.

Fifth seed Daniil Medvedev fought back from a set down and a rolled ankle to progress past Alexander Zverev 6-7 (5-7) 7-6 (7-5) 7-5 in three hours and 10 minutes.

Medvedev rolled his ankle in the sixth game of the second set, going down in pain but played on, in his longest-ever three-set match. The victory is the Russian's 17th in a row. Zverev committed 50 unforced errors across the match.

The Russian will take on Alejandro Davidovich Fokina in the last eight, with the Spaniard winning 6-3 6-4 over Chilean qualifier Cristian Garin.

Jannik Sinner cruised past Stanislas Wawrinka 6-1 6-4 in one hour and 39 minutes to move into the last eight where he will face reigning champion Taylor Fritz. The American won 6-4 6-3 over Hungary's Martin Fucsovics in one hour and 41 minutes.

British 10th seed Cameron Norrie will play 14th seed Frances Tiafoe in the other quarter-final, with the former winning 6-2 6-4 over the higher-ranked Andrey Rublev. Tiafoe won 6-4 6-4 over Alejandro Tabilo in 83 minutes for his 150th career win.

World number two Carlos Alcaraz made it 10 wins from 11 matches in 2023 after defeating Tallon Griekspoor 7-6 (7-4) 6-3 in round three at the Indian Wells Open.

Alcaraz, 19, kicked off his 2023 campaign with eight wins in a row, including an Argentina Open title, before losing to Cameron Norrie in the Rio Open decider.

He has yet to drop a set at this fortnight's tournament in California, following up his opening win over Thanasi Kokkinakis with another strong showing against 31st seed Griekspoor.

The Spaniard will look to keep his strong form going when he meets Jack Draper in the fourth round, after 21-year-old Draper prevailed 7-6 (8-6) 6-2 in a battle of the Brits against Andy Murray.

Murray, who came into the match with six wins from his past seven outings, had an opportunity to take the match by the scruff of the neck but could not capitalise on a set point before going down in a tight tie-break, before Draper took charge.

California's own Taylor Fritz lived up to his fourth seeding, with the defending champion having little trouble in overcoming Argentina's Sebastian Baez 6-1 6-2, and he will play Hungary's Marton Fucsovics for a spot in the quarter-final.

Fucsovics, after upsetting 16th seed Alex De Minaur in the previous round, got the better of Slovakia's Alex Molcan 6-4 6-2.

Former world number three Stan Wawrinka showed he still has some gas in the tank after a surprise 6-2 6-7 (5-7) 7-5 triumph over world number eight Holger Rune, with the 37-year-old showing what he has learned through competing at the top level for as long as the 19-year-old Dane has been alive.

Jannik Sinner, the 13th seed, successfully navigated the challenge of veteran Adrian Mannarino for a 7-6 (9-7) 6-4 victory, Tommy Paul won his top-20 showdown against Hubert Hurkacz 4-6 6-2 6-4, and eighth seed Felix Auger-Aliassime knocked out Francisco Cerundolo 7-5 6-4.

Top seed Carlos Alcaraz and reigning champion Taylor Fritz both overcame challenges to progress into the third round of the Indian Wells Open on Saturday.

Alcaraz won 6-3 6-3 over Thanasi Kokkinakis in one hour and 18 minutes in his opening match of the event, which also marked his return from a fortnight out with a hamstring injury.

The Spaniard, who reached the semi-finals at Indian Wells last year, could return to the number one ranking with victory at this year's event in the absence of Novak Djokovic.

Alcaraz hit 21 winners against the 94th-ranked Australian, dropping only one point on serve in the opening frame.

Fritz went a set down against 2023 Australian Open quarter-finalist Ben Shelton but eventually prevailed 4-6 6-4 6-3 in one hour and 53 minutes.

Both players were excellent on serve throughout the contest, with Fritz earning a break in the 10th game of the second set to tie up the match, before swooping again in the sixth game of the decisive frame.

Veteran Andy Murray moved into the third round with a 6-4 6-3 win over Radu Albot, with the Briton to take on countryman Jack Draper next. Draper won 6-4 6-2 over 24th seed Daniel Evans.

Murray had been set to face 15th seed Pablo Carreno Busta in the second round, but he withdrew due to a muscle injury, allowing Albot into the draw as a lucky loser. Murray's win was his first in straight sets since October.

Seventh seed Holger Rune won 7-5 6-3 over American Mackenzie McDonald, progressing to face Stanislas Wawrinka after he toppled 26th seed Miomir Kecmanovic 7-6 (10-8) 6-4.

Ninth seed Hubert Hurkacz got past Australian Alexei Popyrin 6-3 6-3, setting up a third-round clash with 17th seed Tommy Paul who won 6-3 6-3 over Jan-Lennard Struff.

Eighth seed Felix Auger-Aliassime won 7-6 (7-5) 6-4 over Pedro Martinez, while 11th seed Jannik Sinner got past veteran Richard Gasquet 6-3 7-6 (7-2).

Last week's Mexican Open champion and 16th seed Alex de Minaur was the highest seed to be knocked out on Saturday after a 6-4 6-2 loss to Martin Fucsovics.

Seventh seed Tommy Paul claimed a spot in the Mexican Open final after proving too good for countryman Taylor Fritz in the longest match in Acapulco history on Friday.

Paul edged the third seed 6-3 6-7 (2-7) 7-6 (7-2) in three hours and 29 minutes in their semi-final clash in Acapulco.

World number 23 Paul actually generated a match point late in the second set but spurned his initial chance, then waiting another two hours before winning in the third-set tie-break.

Paul let match point slip at 5-4 in the second set and had to rally back from 3-1 down in the third, but triumphed on his fourth match point.

"I couldn't be happier," Paul said. "The goal for this year was to get the ranking up and get more trophies. I only have one trophy on Tour between singles and doubles.

"You don't get trophies unless your in the final, and hopefully I can play another good match tomorrow and get the winner's trophy."

The 2023 Australian Open semi-finalist will take on Alex de Minaur in Saturday's decider, after he defeated Holger Rune 3-6 7-5 6-2 in two hours and 50 minutes.

In the Chile Open, local Nicolas Jarry progressed into the semi-finals with a 3-6 6-3 6-4 win over German qualifier Yannick Hanfmann. Jarry will face Spaniard Jaume Munar after he won 6-3 3-6 6-2 over Thiago Monteiro.

Third seed Sebastian Baez got past Laslo Djere 7-6 (7-4) 6-4, setting up a semi-final date with Tomas Martin Etcheverry after he won 6-1 6-2 over Dusan Lajovic.

World number five Taylor Fritz showed why he is the highest seed still standing at the Mexican Open after a strong 6-3 6-4 win in Thursday's quarter-final.

Fritz, the third seed, faced sixth seed and world number 15 Frances Tiafoe, and did not allow a single break of serve en route to the 96-minute victory.

He will now face compatriot Tommy Paul in an all-American semi-final after the world number 23 prevailed 6-2 6-2 against Mackenzie McDonald.

The win was Paul's 10th from his past 12 matches, with one of those two losses coming against Novak Djokovic.

Australia's Alex De Minaur is through to the other semi-final after making light work of Japan's Taro Daniel 6-2 6-2 in a surprisingly one-sided contest, considering Daniel was coming off a victory over world number four Casper Ruud.

De Minaur will face Holger Rune after the 19-year-old capitalised on Matteo Berrettini not being at 100 per cent, jumping out to a perfect 6-0 1-0 start before the Italian retired hurt.

Meanwhile, Chile Open second seed Francisco Cerundolo missed out on a potential chance to face his younger brother after going down 6-3 3-6 6-3 against Tomas Martin Etcheverry.

He was one win away from doing his part to set up a quarter-final showdown with Juan Manuel Cerundolo, but the 21-year-old Argentine also did not hold up his end of the bargain, falling 6-2 2-6 7-6 (7-2) to Serbia's Dusan Lajovic.

Laslo Djere ensured it would be a good day for the Serbians with a 7-5 7-5 handling of Italy's Riccardo Bonadio, and he will face third seed Sebastian Baez in the quarter-final after he eliminated hometown hero Cristian Garin 6-4 6-3.
