Andy Murray will continue to play professional tennis for as long as he keeps "seeing progress" in his game, the Scot has revealed.

The former world number one was knocked out of the Hall of Fame Open by Alexander Bublik on Friday, with the Kazakh winning their quarter-final 7-5 6-4 in Newport.

It follows Murray's disappointing second-round exit at Wimbledon to John Isner, and while the 35-year-old wants to see results improve, he was optimistic ahead of the switch from grass to the hard-court season.

"Obviously I just want the results to be a bit better," Murray told the ATP Tour website. "I felt like I had a good chance of [winning] here. If I got through Bublik, it would have been a good opportunity potentially in the semi-finals.

"But… to have my body feeling pretty good and getting lots of matches in is important for me."

Murray did have some success on grass this year, including reaching the final of the Stuttgart Open before losing to Matteo Berrettini.

"There were some good moments, but also some tough ones," he added. "Today's match and the loss at Wimbledon were disappointing and frustrating for me, but then I also had my best wins in a while in Stuttgart.

"So a bit up and down, but a little bit of progress overall and I'll try and keep that going through the hard-court summer.

"[I want] to continue to improve. If I keep seeing progress I’ll continue to keep playing."

Murray met NFL quarterback Kirk Cousins earlier in the week, with the Minnesota Vikings star praising the tennis supremo's "grit", and Murray revealed Cousins was looking to incorporate tennis into his own preparations for the new season.

"I'd never actually met any NFL athletes before, but he seemed like he loved his tennis and he was saying that he feels like a lot of the movements you make in tennis are similar to a quarterback," Murray added.

"He would prefer to do an hour of tennis to an hour of agility drills, which I can understand as you get a little bit older, trying to keep things fresh and fun in training in pre-season is important."

Alexander Bublik beat Andy Murray to reach the semi-finals of the Hall of Fame Open, while Dominic Thiem was knocked out of the Swedish Open on Friday.

Bublik and Murray have now beaten each other two times apiece this year after the third seed won 7-5 6-4 in Newport.

The Kazakh overpowered the three-time grand slam champion to move into the last four, winning 80 per cent of his first-serve points and breaking three times.

Murray hit back straight after being broken at the start of the second set, but the former world one trailed 4-3 after failing to hold for a third time and Bublik did not give him another look-in.

Bublik will do battle with Jason Kubler for a place in the final after he defeated fellow Australian James Duckworth 7-5 7-6 (7-3).

Sebastian Baez ended Thiem's encouraging run to the quarter-finals with a 6-2 6-7 (5-7) 6-4 win in Bastad.

Thiem, who has endured an injury nightmare, won his first match 14 months by beating Emil Ruusuvuori in the first round and followed that up by getting the better of Roberto Bautista Agut, but the former US Open champion will go no further.

Argentinian Baez will now come up against Andrey Rublev after the second seed from Russia saw off Laslo Djere 7-5 6-4.

Pablo Carreno Busta blew Diego Schwartzman away in a 6-1 6-0 thrashing, while Francisco Cerundolo got past Aslan Karatsev in straight sets.

Casper Ruud was a surprise second-round loser as the Swedish Open defending champion fell to Francisco Cerundolo, while the favourites battled through at the Hall of Fame Open.

Ruud, a French Open finalist and defending champion in Bastad , lacked his usual composure as world number 39 Cerundolo broke him three times to win 6-4 3-6 7-5 on Wednesday.

That marked a first top-10 career victory for Cerundolo after defeating world number five Ruud, guiding him to his first quarter-final appearance at the tournament.

"I'm feeling amazing, I'm really happy," said Cerundolo, whose previous best result was beating world number 24 Gael Monfils. "It's amazing getting my first Top 10 win. It's been the best year so far in my career.

"He's a French Open finalist and was the defending champion here, so it was a big challenge for me and I'm happy to go through."

Aslan Karatsev awaits in the quarter-finals Cerundolo after downing Frenchman Hugo Gaston 6-2 6-4.

Fifth seed Pablo Carreno Busta survived a first-set scare to defeat 2016 champion Albert Ramos-Vinolas 4-6 7-6 (7-5) 7-5.

The victory was Carreno Busta's 250th tour-level triumph and he will next face third favourite Diego Schwartzman, who overcame Elias Ymer in straight sets.

Third seed Alexander Bublik was made to work for a 6-3 3-6 6-2 second-round victory over Jack Sock in Newport and Andy Murray edged past Wimbledon doubles champion Max Purcell.

Murray needed almost two-and-a-half hours to get the better of Purcell, eventually triumphing 4-6 6-2 6-1 to tee up a last-eight meeting with Bublik.

Fourth favourite Maxime Cressy had little trouble in beating fellow American Mitchell Krueger 6-3 6-4 and will next face Steve Johnson, who progressed past seventh seed Jiri Vesely with a walkover.

Benjamin Bonzi, ranked as fifth seed in the United States, eased past Christopher Eubanks in straight sets, while James Duckworth triumphed 7-5 3-6 6-2 over Quentin Halys.

John Isner joined the list of favourites who made the third round in routine fashion, beating Peter Gojowczyk in straight sets 6-3 7-6 (8-6), before top seed Felix Auger-Aliassime faced some adversity against Jason Kubler following the Australian's strong run into the fourth round of Wimbledon.

Auger-Aliassime has a slight advantage, leading 6-4 3-6 6-5 before play was suspended due to poor light. When play resumes, Kubler will serve with a chance to force a third-set tiebreak.

Daniil Medvedev eventually mastered the windy conditions as he came from behind to keep his Mallorca Championships defence alive, but Jannik Sinner and Diego Schwartzman crashed out in Eastbourne. 

World number one Medvedev fought back from a set down to defeat Aslan Karatsev 3-6 6-4 6-2 and advance to a quarter-final against fifth seed Roberto Bautista Agut, who was granted a walkover after Nick Kyrgios pulled out with an abdominal issue. 

The Russian got just 48 per cent of his first serves in during a blustery opening set before improving to 68 per cent in the second and controlling the decider as Karatsev struggled with injury. 

"It was tough to play [in] rhythm. It felt like many points were just whoever managed to put the ball in the court was going to win the point," Medvedev said of the tricky conditions. 

"It was not easy but I'm happy to win because that's the most important [thing]. 

"Last year was amazing. I played great tennis. Hopefully I can do the same this year. I like it here in Mallorca, so hopefully I can stay as long as possible in the tournament." 

Alongside Medvedev and Bautista Agut, Stefanos Tsitsipas is the only other seed left in the draw after he overcame Ilya Ivashka 6-4 6-4. 

Denis Shapovalov was a 6-4 6-1 loser against Benjamin Bonzi, Pablo Carreno Busta went down 6-3 6-4 to Antoine Bellier and Sebastian Baez's meeting with Daniel Altmaier ended in a 6-2 2-6 6-4 defeat for the Argentine. 

At the Eastbourne International, second seed Sinner suffered a 6-3 3-6 6-3 loss to Tommy Paul as he made his return from a knee injury sustained at the French Open.

World number 13 Sinner remains without a grass-court win in his ATP Tour career, while Paul will next face defending champion Alex de Minaur, who overcame Lorenzo Sonego 7-6 (7-3) 6-2 in a repeat of last year's final. 

Jack Draper defeated fourth seed Diego Schwartzman 7-5 7-6 (7-3) to advance to the quarter-finals and Cameron Norrie cruised past Brandon Nakashima in straight sets.

There were also wins for Maxime Cressy, Alexander Bublik and Taylor Fritz. 

A spirited fightback from Nick Kyrgios saw the Australian beat second seed Stefanos Tsitsipas in the Halle Open on Wednesday.

Kyrgios suffered a disappointing semi-final defeat to Andy Murray in Stuttgart last week, but looked greatly improved against Tsitsipas as he recovered from a set down to win 5-7 6-2 6-4.

It was the second serve of both men where Kyrgios shone, winning 76 per cent (28 of 37) of points on his second serve, and 58 per cent (23 of 40) on his opponent's.

"Stef is one of the best players in the world at the moment and he's going to have some amazing results and I'm sure many, many grand slams," Kyrgios said following his win.

"I don't know if I can say the same for me, but I'm happy to still be able to produce this level with the tournaments I play. It is a testament to how hard I do work when I'm not playing."

He will face Pablo Carreno Busta in the quarter-finals after the Spanish sixth seed beat Sebastian Korda 6-4 0-6 6-3.

Elsewhere, Hubert Hurkacz will face Felix Auger-Aliassime in the last eight after defeating Ugo Humbert 7-6 (7-5) 6-3, while the Canadian also won in straight sets against Mackenzie McDonald 7-6 (9-7) 6-1.

The one remaining first round match saw number one seed Daniil Medvedev beat David Goffin 6-3 6-2 to set up a second round clash with Ilya Ivashka.

At the Queen's Club Championships, sixth seed Denis Shapovalov was eliminated by Tommy Paul 6-4 2-6 6-4, with the American now scheduled to face Stanislas Wawrinka in the second round.

It means that six of the eight seeds in west London were knocked out in the first round, with Matteo Berrettini and Marin Cilic the only remaining seeds. The latter sealed his place in the quarter-finals on Wednesday with a 7-6 (8-6) 7-5 win over Alexander Bublik.

Cilic will play Finland's Emil Ruusuvuori in the last eight after he beat home favourite Jack Draper 6-2 7-6 (7-2).

The best contest of the day came between Alejandro Davidovich Fokina and Alex de Minaur, with the former coming from behind to win 4-6 6-4 7-5 to set up a quarter-final with Botic van de Zandschulp, who beat Grigor Dimitrov 7-6 (7-5) 6-3.

Andrey Rublev was a surprise first-round loser at the Halle Open, while numerous seeds fell on the first day of the Queen's Club Championships.

Rublev came unstuck against Georgian Nikoloz Basilashvili, succumbing to a 7-6 (7-1) 6-4 loss as the world number eight crashed out in Germany.

Laslo Djere progressed after Henri Squire retired when 4-3 down, while sixth seed Pablo Carreno Busta secured a 6-3 7-6 (7-5) over French Open quarter-finalist Holger Rune.

Ugo Humber got the better of a topsy-turvy affair against qualifier Radu Albot, eventually triumphing 6-7 (4-7) 7-6 (7-4) 7-5 and Mackenzie McDonald defeated Marc-Andrea Huesler in straight sets.

Fourth favourite Taylor Fritz went down 6-3 6-3 against British wildcard Jack Draper, his first career win against a top-20 ranked player.

Reilly Opelka, the eighth seed, crashed out in the first round to New Zealand's Alex de Minaur, who claimed a straightforward 6-4 6-4 win.

Grigor Dimitrov, who won the event in 2014, battled past third seed Cameron Norrie 6-7 (2-7) 6-1 6-4, while Spaniard Alejandro Davidovich Fokina eased past compatriot Albert Ramos-Vinolas 7-5 6-4.

Alexander Bublik was 6-3 up before Italian Lorenzo Musetti retired, while seventh seed Marin Cilic capped the day's play in London by beating home hope Liam Broady 6-1 4-6 7-5.

Matteo Berrettini survived a scare to eventually progress to the fourth round at the Indian Wells Masters on Tuesday.

The Italian sixth seed had to fight from 2-5 down in the second set and saved three set points, before powering through to triumph 6-4 7-5 over Lloyd Harris.

"I got a little bit nervous," Berrettini said post-match. “I didn’t like how I handled the start of the second set. I let the anger get out a little bit, which helped. I found the right balance in order to break him in the important moment and then I had the momentum.”

The world number six found another level in reeling off five straight games, and will now face unseeded Miomir Kecmanovic, who accounted for Botic van de Zandschulp 7-6(6-3) 7-5.

Taylor Fritz was also pushed by Spanish qualifier Jaume Munar, taking a third-set tiebreaker to progress to the fourth round.

The 20th-seeded was made to work for it in a match that lasted just under three hours, but Munar feel short in the clutch, with two unforced forehand errors in the closing tiebreak to give Fritz a three-point gap.

In Tuesday's last game, Andrey Rublev showed rare composure to progress past Frances Tiafoe 6-3 6-4. 

Neither got off to the best of starts, with Rublev and Tiafoe sharing service breaks in the opening four games of the first set. The characteristically volatile Rublev managed to regroup, though, and stayed calm even when Tiafoe got his home crowd on side. 

Despite a low 67 percent on first serve, Rublev won 83 percent of those points, while Tiafoe did himself no favours with an even lower 58 percent first-serve rate.

Last-year’s semi-finalist will face 29th-seeded Alex de Minaur, who defeated Tommy Paul 7-6(6-2) 6-4.

The Australian world no. 31 faced immediate difficulty on service, with only his second service game going to eight consecutive deuces, after five saved break points. He eventually saw the match through, after breaking for 4-3 in the second set.

Fellow seeds Hubert Hurkacz and Grigor Dimitrov both went through relatively unscathed, with respective wins over Steve Johnson and Alexander Bublik.

Dimitrov will face John Isner, who saw past Diego Schwartzman 7-5 6-3 in Tuesday’s other result.

Third seed Alexander Zverev has been knocked out of the Indian Wells Masters by Tommy Paul in his first game since his expulsion from last month's Mexican Open for unsportsmanlike conduct.

Unseeded American Paul triumphed over the German 6-2 4-6 7-6 (7-2) in two hours and 17 minutes, rallying back from a break down in the final set.

Paul hit less winners, 26-21 to Zverev but made less unforced errors 25-19, while his serve and volley game was a key feature.

"I played a really high level today," Paul said during his on-court post-game interview. "The last time I played him, I played well, I put pressure on him so I knew how i wanted to play so I came out and executed him well.

"I played well when it came down to the breaker, so I'm pretty happy with my performance."

Zverev had not played since being expelled in Acapulco after a stunning outburst where he struck his racquet on the umpire chair several times after a doubles defeat.

Ninth seed Felix Auger-Aliassime was a major casualty, going down to Dutchman Botic van de Zandschulp 7-6 (7-4) 6-7 (4-7) 6-3 in three hours and 15 minutes.

The Canadian had 36-27 winners but was let down by 43-26 unforced errors, along with converting only two of his 10 break points.

Van de Zandschulp had failed to take three match points in the second set but showed composure to finish the job in the third.

Wild card Andy Murray was also eliminated in the second round, blowing three set points in the first set before going down to 31st seed Alexander Bublik 7-6 (11-9) 6-3 in two hours and one minute.

Last year's Wimbledon runner-up and Italian sixth seed Matteo Berrettini needed more than two hours to get past world number 86 Holger Rune 6-3 4-6 6-4.

Seventh seed Andrey Rublev defeated Dominik Koepfer 7-5 6-4 to extend his win streak to 10 matches, while 11th seed Hubert Hurkacz beat Oscar Otte 6-3 3-6 6-3.

Other seeds to be eliminated were 22nd seed Aslan Karatsev who went down 7-6 (7-5) 6-4 to American Steve Johnson, while 24th seed Marin Cilic lost 6-7 (7-9) 6-3 7-6 (8-6) to Miomir Kecmanovic.

Andy Murray set up a second-round clash with Felix Auger-Aliassime at the Rotterdam Open, but fourth seed Hubert Hurkacz was stunned by Lorenzo Musetti. 

Former world number one Murray secured an impressive 7-6 (8-6) 6-4 victory over Alexander Bublik, who entered the tournament on the back of the biggest win of his career over Alexander Zverev in the Montpellier final last week. 

Murray stopped the Kazakh serving out the opening set with a crucial break and appeared in fine form as he closed out the win. 

"There were some tough moments in the first set for both of us. I just managed to come through at the end of it. Some great returns off some big second serves from him at the end and I did a good job," said Murray. 

"It’s not easy playing against someone like that, huge serves, a lot of drop shots and you’ve got to keep your focus and I did that well." 

Up next for Murray is Australian Open quarter-finalist and third seed Auger-Aliassime, who came from a set down to beat qualifier Egor Gerasimov 3-6 6-2 6-2. 

"[Auger-Aliassime] started the year pretty well and is one of the best young players just now," said Murray. "I'll need to be on my game if I want to beat him, but it's a great test for me and we'll see what happens out there." 

Musetti advanced to the quarter-finals after a 6-3 5-7 6-4 triumph over Hurkacz, dropping just one point on his first serve in the decisive set. 

Cameron Norrie defeated Karen Khachanov 6-4 7-6 (7-5) to reach the last eight, while Alex De Minaur was also a 7-6 (8-6) 1-6 6-4 victor against Mackenzie McDonald in the second round.

Alexander Bublik claimed his first ATP Tour title with a stunning straight-sets victory over Alexander Zverev in the Open Sud de France final.

The 24-year-old went into Sunday's match without a career win over a top-five opponent and having lost two finals in a career-best season in 2021.

He was not to be denied this time, however, powering his way to a 6-4 6-3 win over the world number three in Montpellier in just one hour and 10 minutes.

The Kazakhstani lost just four points behind his first serve throughout the match, the only blip coming when he handed Zverev a break back to love after moving 3-2 ahead in the first set.

After regaining the advantage, Bublik survived two more break points before closing out the opener and the pressure only increased on the Zverev serve in the second set.

Bublik broke to love to lead 3-2 and again in the final game as Zverev's resistance wilted.

He can now look forward to rising to a career-high place in the rankings when the updated list is published on Monday.

Alexander Zverev will face Alexander Bublik in the Open Sud de France final after easing to victory over Mikael Ymer on Saturday.

The top seed is seeking a 20th tour-level title and has yet to drop a set in his three matches in Montpellier after beating Bublik 6-1 6-3.

Ymer eliminated Gael Monfils and Richard Gasquet en route to the semi-finals, but the world number 83 struggled against Zverev in his third straight loss to the German. 

Zverev was triumphant in his last appearance in this tournament five years ago and is the strong favourite heading into Sunday's final with Bublik.

"I am in the final and I am happy about that," Zverev said in his on-court interview. "I played a pretty good match. I think I played one bad game in the whole match. 

"Overall I am happy to be in another final, playing against Alex who I have known since I was 12 years old, so hopefully it will be a fun match."

Bublik also claimed a routine win in his semi-final against Filip Krajinovic, the sixth seed prevailing 6-4 6-2 in a little over an hour.

The 24-year-old is through to his fifth ATP Tour final, having most recently gone all the way at the Singapore Open last February, where he lost to Alexei Popyrin.

At the Tata Open Maharashtra, Mikael's older brother Elias Ymer squandered three match points to lose 5-7 7-6 (7-4) 7-5 to Joao Sousa in Pune.

The Swedish qualifier had defied the odds to make it to the semi-finals and took the opening set against Sousa, before recovering from 4-1 down to level up the second set 4-4.

But Sousa edged the tie-break and survived three match points in the 10th game of the deciding set, which he would go on to win.

Sousa will face Emil Ruusuvuori in Sunday's final after the world number 87 overcame Kamil Majchrzak 6-3 7-6 (7-0) earlier in the day.

It marks the first tour final that Ruusuvuori has reached, while Sousa is in the hunt for a fourth title at this level.

Top seed Aslan Karatsev exited the Astana Open at the last-16 stage with a straight-sets defeat to Emil Ruusuvuori on Thursday.

World number 84 Ruusuvuori saved a set point in the first-set tie-break on his way to a 7-6 (8-6) 6-4 victory and will now face Ilya Ivashka for a place in the semi-finals.

There was nearly another upset as home hopeful Alexander Bublik, seeded second, had to recover from a set down to overcome Miomir Kecmanovic 2-6 6-3 7-5.

Carlos Taberner awaits Bublik in the next round after the Spaniard beat Egor Gerasimov 5-7 7-6(5) 7-5.

Kwon Soon-woo and James Duckworth saw off Dusan Lajovic and Filip Krajinovic respectively in straight sets to remain a course for glory.

At the Moselle Open in Metz, meanwhile, Gael Monfils took out Philipp Kohlschreiber 7-6(2) 6-4 to reach the quarter-finals on home soil.

Tournament favourite Hubert Hurkacz made light work of 2016 champion Lucas Pouille with a 6-2 6-3 victory to set up a meeting with Andy Murray in the quarter-finals.

Elsewhere on Thursday, German qualifier Peter Gojowczyk proved too strong for Karen Khachanov and will now face Marcos Giron, who upset fourth seed Alex de Minaur.

Rafael Nadal saw off Alexei Popyrin to reach the Madrid Open quarter-finals on a day that saw Daniil Medvedev and Stefanos Tsitsipas suffer surprise defeats.

World number two Nadal, chasing a record-extending sixth title on home soil, advanced 6-3 6-3 in a time of one hour and two minutes on Thursday.

Popyrin, playing in his first last-16 match at a Masters 1000 event, broke Nadal in the sixth game of the opening set but the Spaniard otherwise looked comfortable.

Nadal converted four of his six break points to advance through to the last eight for a 15th time, where Alexander Zverev awaits.

"It was difficult," Nadal said in his on-court interview. "The court today was slippery, it was very fast, very dry conditions. The ball was flying a lot. The beginning was super tough. 

"He was hitting every ball and hitting the spots. I'm happy with the victory. It was an important victory, he came here playing well. Every match is tough."

Zverev, who won the competition in 2018, beat British number one Dan Evans 6-3 7-6 (7-3) to set up a meeting with Nadal

However, second and fourth seeds Medvedev and Tsitsipas saw their participation come to an end at the hands of Cristian Garin and Casper Ruud respectively.

Medvedev, who is still yet to reach the quarters in Madrid, lost the only break of serve in the third game of the opening set but recovered by taking the second set in a tie-break.

Garin dominated the deciding set, the world number 25 breaking Medvedev twice and, after a short delay to fix a broken net, advanced 6-4 6-7 (7-2) 6-1.

Tsitsipas, who held championship point against Nadal in the Barcelona Open final, failed to break Ruud on a single occasion as he fell 7-6 (7-4) 6-4.

Alexander Bublik is next up for Ruud after beating Aslan Karatsev 6-4 6-3, while Matteo Berrettini - 7-6 (7-4) 6-4 winner against Federico Delbonis - will meet Garin.

Also vying for a place in the semi-finals are John Isner and Dominic Thiem, who are set to face off after beating sixth seed Andrey Rublev and Alex de Minaur respectively.
