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.

Carlos Alcaraz moved into the quarter-finals of the Barcelona Open with a straight-sets defeat of Roberto Bautista Agut, but it was a miserable Thursday for Alexander Zverev on home soil.

Defending champion Alcaraz won an all-Spanish contest with Bautista Agut 6-3 7-5 on Pista Rafa Nadal.

Top seed Alcaraz will face another compatriot in the form of Alejandro Davidovich Fokina, who saw off Emil Ruusuvuori, for a place in the last four in his homeland.

Eyeing a third title of the year, 19-year-old US Open champion Alcaraz was a break down at 3-2 in the opening set before winning six games in a row to take the opener.

Bautista Agut broke the teenager's serve twice midway through the second set, but the favourite reeled off nine points in a row to seal victory in an hour and 54 minutes.

Second seed Stefanos Tsitsipas defeated Denis Shapovalov 6-3 6-2, and Jannik Sinner, the fourth seed, battled past Yoshihito Nishioka 6-1 4-6 6-3, but Casper Ruud was beaten by Francisco Cerundolo in straight sets.

Lorenzo Musetti and Dan Evans advanced at the Real Club de Tenis Barcelona-1899 along with Alex de Minaur, who went through with a walkover as Grigor Dimitrov withdrew due to injury.

Meanwhile, there will be no third BMW Open title for Zverev in Munich this week after he suffered a shock loss at the hands of world number 82 Christopher O'Connell.

Australian O'Connell saw off the third seed 7-6 (7-2) 6-4, while defending champion and top seed Holger Rune ousted Yannick Hanfmann 6-3 6-4, and Taylor Fritz got past Marton Fucsovics in three sets.

Lorenzo Sonego was another seed who bowed out, Cristian Garin beating the Italian 6-3 7-6 (7-3).

Stefanos Tsitsipas breezed into the third round of the Barcelona Open with a straight-sets win over Pedro Cachin on Wednesday.   Tsitsipas took 79 minutes to see off Argentine Pedro Cachin 6-4 6-2 on Pista Rafa Nadal.   The second seed from Greece did not face a break point and won all three that he fashioned to set up a meeting with Canadian Denis Shapovalov, who got the better of Jozef Kovalik 6-4, 6-3.   Jannik Sinner, the fourth seed from Italy, eased to a 6-2 6-4 win over Diego Schwartzman at the Real Club de Tennis Barcelona-1899.   Cameron Norrie and Lorenzo Musetti will do battle in round three after defeating Pavel Kotov and Jason Kubler respectively in straight sets.   Karen Khachanov beat Nicolas Jarry 6-4 6-4, while Grigor Dimitrov, Dan Evans, Alex de Minaur, Yoshihito Nishioka and Francisco Cerundolo also celebrated midweek wins.   Rain hit the schedule hard at the BMW Open, where Aslan Karatsev was leading Daniel Altmaie 3-0 in the third set when play was suspended in the only singles action of the day.  

Novak Djokovic was forced to come from a set down to beat Luca Van Assche 6-7 (4-7) 6-3 6-2 in the Srpska Open second round on Wednesday.

Teenager Van Assche took a big step towards a stunning victory after going a set ahead, but the world number one rallied to seal his progression against the stubborn Frenchman.

Djokovic, who admitted his right elbow "was not in an ideal condition" earlier this week after a shock exit at the Monte Carlo Masters, was not at his brilliant self as Van Assche took the first set by finding two crucial breaks in the tie-break.

The Serbian improved, though, and he dominated the second set by holding all five of his service games and breaking twice to take the match to a decider.

With the first two games of the final set going against serve, Djokovic took over to win four of the next six and secure a comeback triumph.

Just over a month ahead of the French Open, Djokovic will be glad to have battled to victory in Banja Luka as he prepares for an attempt to win a record 23rd grand slam title at Roland Garros having already claimed the Australian Open crown earlier this year.

Casper Ruud clinched his 10th career ATP title with a straight-sets victory over Miomir Kecmanovic in Sunday's Estoril Open final, while Roberto Carballes Baena won the Grand Prix Hassan II.

Having enjoyed the best season of his career in 2022, Ruud was bidding for his first trophy success of 2023 in Portugal, and the world number five made a flying start to his clash with Kecmanovic.

Ruud wrapped up the opener in just 36 minutes, taking control with a huge forehand winner to break in just the third game.

The Norwegian navigated two three-set contests in order to reach the showpiece, and it looked like another of his matches may go the distance when Kecmanovic recovered to force a second-set tie-break.

However, a dipping backhand saw Ruud secure the second of two crucial mini breaks, and he took the first of his three championship points to cap a fine week with silverware, sealing a 6-2 7-6 (7-3) win.

Elsewhere, Carballes Baena won just his second career title, triumphing on the clay in Marrakesh where he beat Alexandre Muller 4-6 7-6 (7-3) 6-2.

France's Muller showed no signs of being overawed on his first final outing as he took the opener in impressive fashion, but Carballes Baena edged a tie-break in the second before dominating the decider.

Carballes Baena's triumph – recorded in just under three hours – gave him his first title since the 2018 Ecuador Open, which also came on his favoured clay surface.

Top seed Frances Tiafoe won two matches in a day to progress into the Houston Open semi-finals, while five other seeds bowed out on a busy Saturday of action.

Persistent rain this week in Houston meant the past three days of play have not been completed forcing a massive pile-up of matches on Saturday with the conditions clearing up.

Tiafoe took on Steve Johnson in the morning, winning 6-2 6-4 in the second round, before toppling Australian sixth seed Jason Kubler 6-4 6-4 in the quarter-finals.

The American, who only had a break of two and a half hours between his two matches, said: "I haven’t played two matches in one day in a long time.

"I thought it was unbelievable how I was able to come out here and play so well."

Tiafoe will take on Dutchman Gijs Brouwer in the last four after he got past fourth seed John Isner 6-4 7-6 (7-4), before taking down fifth seed J.J. Wolf 6-3 6-4.

Second seed Tommy Paul was another fancied American to bow out on Saturday, losing 7-6 (8-6) 6-2 to German qualifier Yannick Hanfmann in the second round.

Hanfmann progressed to the semi-finals where he will face Argentinian eighth seed Tomas Martin Etcheverry, with the German getting past Czech qualifier Tomas Machac 6-2 6-1.

Machac had bundled out American seventh seed Marcos Giron 6-4 6-4 in the second round.

Etcheverry progressed with victories over Australia's Max Purcell and Chile's Cristian Garin, winning the latter 6-1 6-7 (2-7) 6-3 in more than two and a half hours.

Only one match was able to be completed on Friday at the Houston Open as organisers announced they would try to protect the playing surface for a busy weekend of action.

It was the third day in a row that has been washed out due to persistent rain, but after completing their first set on Wednesday, and their second set on Thursday, Max Purcell was allowed to finish off his 6-4 3-6 6-3 win over Daniel Altmaier.

It was the final first-round matchup yet to conclude, although there is still a second round, quarter-finals, semi-finals and the final to schedule in limited time before the ATP Tour rolls on.

The tournament's top seed, Frances Tiafoe, is yet to play a match yet after receiving a first-round bye, and it is the same case for second seed Tommy Paul.

In a statement, tournament director Bronwyn Greer said: "We want to ensure that our courts are in the best possible condition to complete our tournament this weekend, and with that in mind we have decided to forgo play today with the exception of that first-round match that is deep into the third set."

Thursday's action at the Houston Open has again been called off without any matches completed due to persistent rain in the area.

It is the second day in a row without a match being completed after Wednesday's play only made it through one set.

Max Purcell took the first set of his match against Daniel Altmaier on Wednesday, before Altmaier came back to win the second set on Thursday, and they will hope to complete the match on Friday when they resume with Purcell leading 6-4 3-6 4-3.

John Isner will likely have a do-or-die tie-breaker as soon as his match with Gijs Brouwer resumes, as he trails 6-4 5-6 with the Dutch competitor on serve.

The only other match underway is locked at 4-4 between Denis Kudla and J.J. Wolf.

Wednesday's play was rained out at the Houston Open with only one set completed, while third seed Brandon Nakashima withdrew from the event.

Persistent rain forced an early abandonment of action on the clay courts in Houston, with all eight second-round matches pushed back to Thursday.

Max Purcell's clash with Daniel Altmaier was the only match to get underway, with the Australian leading 6-4 before rain intervened.

Top seed Frances Tiafoe was due to open his campaign against Steve Johnson, with second seed Tommy Paul to face Yannick Hanfmann.

Nakashima's withdrawal for an undisclosed reason meant lucky loser Zizou Bergs will replace him and take on Cristian Garin.

America's J.J. Wolf was the top seed in action on Tuesday at the Houston Open and he had no issue in his 6-3 6-2 first-round victory over Jordan Thompson.

Wolf, the fifth seed at the United States' only clay court event on the ATP Tour calendar, needed just 75 minutes to send the Australian home early on the back of a rock-solid serving performance.

Thompson was not able to produce a single break point opportunity in the match, and Wolf left an exclamation point on the contest by winning the final five games to run away with the win.

Meanwhile, seventh seed Marcos Giron gave the American crowd another win to cheer for in his 6-0 6-2 demolition of Ecuador's Emilio Gomez.

The chance for the double-bagel was there for Giron after winning the first 11 games to race out to a 6-0 5-0 lead, but he blew four match points as Gomez showed no quit and secured a break to at least take the match over the 60-minute mark.

Eighth seed Tomas Martin Etcheverry prevailed 6-3 6-4 in his all-Argentine clash against Juan Manuel Cerundolo, taking a 3-2 lead in their overall head-to-head meetings after rising 21-year-old Cerundolo took the past two.

German qualifier Yannick Hanfmann booked a second-round matchup against second seed Tommy Paul after a hard-fought 6-4 3-6 6-2 triumph over Japan's Yosuke Watanuki, while Chile's Cristian Garin had little resistance in his 6-3 6-0 victory in a South American showdown against Bolivia's Hugo Dellien.

In the late window, Jack Sock failed to complete the United States clean sweep for the day as he fell 6-2 6-4 to the Czech Republic's Tomas Machac.

Santiago's own Nicolas Jarry thrilled his hometown crowd with a stirring come-from-behind 6-7 (5-7) 7-6 (7-5) 6-2 triumph in Sunday's Chile Open final against Tomas Martin Etcheverry.

Jarry, 27, had not made it through to an ATP final since his first and only title win at the 2019 Swedish Open, but the wait was worth it as the Santiago crowd treated him like royalty.

There were no breaks of serve in the opening set, and only one opportunity, but Jarry found himself a set down for the second match in a row after falling short in the tiebreaker.

But just like he did in his semi-final comeback against Jaume Munar, Jarry dug in and quickly ran out to a 3-0 lead in the second set.

It was short-lived, as Etcheverry rallied back to tie things up and force another tiebreaker, when Jarry turned around a 4-2 deficit and rattled off three important points in a row to gain the ascendancy, successfully serving it out to take things to a decider.

After posting an accurate first serve percentage of at least 67 per cent in each of the first two sets, Etcheverry fell apart in the third, landing only 36 per cent of his first serves fair, and winning just half (11-of-22) of his total service points.

Meanwhile, when it mattered most, Jarry's serve became overwhelming, winning 94 per cent (16-of-17) of his service points to slam the door shut on his Argentine challenger.

Alex de Minaur secured his first ATP 500 title on Saturday after coming from behind to defeat Tommy Paul 3-6 6-4 6-1 in the Mexican Open final.

It was a tremendous week in Acapulco for the Australian, having eliminated world number 10 Holger Rune in the semi-final en route to his seventh title overall, with the first six all at the ATP 250 level.

Against Paul, De Minaur blew a pair of break points in the opening set, and then gave up the break in the very next game, allowing the American to serve things out safely to take the first frame.

But mistakes started to creep into Paul's game the longer the match went. After landing 75 per cent of his first serves fair in the opener and avoiding any double-faults, Paul's first serve percentage dropped to 46 in the second, and he committed a pair of doubles.

He committed another two double-faults in the decider to hand De Minaur the early break, and his play from the baseline also deteriorated, hitting just six winners to go with 14 unforced errors.

Known for his resilience, De Minaur had to save five break points to hold serve in the opening game of the third set, but he held his nerve, and churned out five consecutive games as Paul ran out of gas.

The 500 ranking points will see the Aussie climb to 18th in the world, with his career-best mark of 15th now within reach.

Meanwhile, the fairytale continued for Nicolas Jarry at the Chile Open, with the Santiago-born talent electrifying his home crowd with a 1-6 7-6 (7-4) 6-1 semi-final victory over Jaume Munar.

Jarry will get a chance for the second ATP title of his career, and the first since 2019, when he meets Tomas Martin Etcheverry in the final.

Etcheverry emerged victorious 7-5 6-3 in an all-Argentine showdown against third seed Sebastian Baez, earning his first final appearance at this level.

Alex De Minaur secured his first ATP 500 title on Saturday after coming from behind to defeat Tommy Paul 3-6 6-4 6-1 in the Mexican Open final.

Meanwhile, the fairytale continued for Nicolas Jarry at the Chile Open, with the Santiago-born talent electrifying his home crowd with a 1-6 7-6 (7-4) 6-1 semi-final victory over Jaume Munar.

Jarry will get a chance for the second ATP title of his career, and the first since 2019, when he meets Tomas Martin Etcheverry in the final.

Etcheverry emerged victorious 7-5 6-3 in an all-Argentine showdown against third seed Sebastian Baez, earning his first final appearance at this level.

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.
