Jannik Sinner continued his push for an ATP Finals spot with a straight-sets defeat of Reilly Opelka in the first round of the Vienna Open, while Carlos Alcaraz exacted revenge on Andy Murray.

Sinner won his fourth title of what has been an outstanding season for the Italian in Antwerp last weekend and is only 110 points adrift of Hubert Hurkacz in the battle for the final place in the season-ending event in Turin.

Murray did the 20-year-old a favour by knocking Hurkacz out of the ATP 500 tournament in the Austrian capital on Monday and seventh seed Sinner eased to a 6-4 6-2 win over American Opelka two days later.

Sinner, who will overtake Pole Hurkacz if he reaches the semi-finals this week, won 93 per cent of points behind his first serve and did not face a break point in a resounding win and will play Dennis Novak in the second round.

Murray beat Alcaraz at Indian Wells this month, but the 18-year-old rising star from Spain turned the tables on the three-time grand slam champion with a 6-3 6-4 second-round win in Vienna.

Former world number one Murray struggled with his serve and was broken five times as he made an early exit.

Third seed Matteo Berrettini beat Nikoloz Basilashvili 6-7 (5-7) 6-2 6-3 to reach the third round, while Diego Schwartzman, Gael Monfils and Lorenzo Sonego moved into the second round.

In the St Petersburg Open, defending champion Andrey Rublev beat Ilya Ivashka 6-4 6-4 to reach the quarter-finals along with Denis Shapovalov, a 2-6 6-3 6-0 winner against Pablo Andujar.

Jan-Lennard Struff also moved into the last eight, with Karen Khachanov and Marin Cilic securing first-round wins.

Stefanos Tsitsipas survived a minor scare in the first round of the Vienna Open before ultimately going on to beat Grigor Dimitrov in straight sets.

It was neck-and-neck for much of the first set, with neither player losing serve, but Dimitrov appeared to have the upper hand when he got to 6-3 in the tiebreak.

Tsitsipas recovered emphatically, however, the top seed reeling off five successive points to win the set and he went on to book his spot in the second round thanks to a 7-6 (8-6) 6-4 victory. He will face Frances Tiafoe next.

"Grigor is a tough competitor and the level of tennis was really high today. We both competed at our highest [level]," Tsitsipas said afterwards.

"That was great tennis that was being played during the entire match and I got really close to my [best] offence and showed incredible attitude [in] the last game, which was the one that was the most crucial of the match."

Alexander Zverev, seeded second, was also made to work in his first-round clash with Filip Krajinovic.

While he blew the Serbian away in the first set, he found himself 5-2 down in the second as Krajinovic looked set to level the match, but Zverev scrapped his way back and then served to love to win 6-2 7-5. Alex de Minaur awaits the German.

Casper Ruud and Felix Auger-Aliassime, seeded fourth and sixth respectively, were two other high-ranking players who also secured progression, boosting their ATP Finals qualification hopes.

Ruud was pushed hard by Lloyd Harris but eventually outfought the South African in his 7-5 7-6 (7-2) win, while Auger-Alisassime made fairly light work of Ricardas Berankis 6-3 6-2.

Indian Wells champion Cameron Norrie, who is also in with a shot of reaching the ATP Finals, beat Marton Fucsovics 7-6 (7-4) 6-1 to set up a meeting with Auger-Aliassime – the British number one is 11th in the FedEx ATP Race to Turin rankings, one above his next opponent.

At the St Petersburg Open, fifth-seed Taylor Fritz was the highest-ranked player in action and he needed a little over an hour to beat Emil Ruusuvuori 6-1 6-4.

Pablo Andujar defeated Federico Delbonis to set up a meeting with second seed Denis Shapovalov, while Ilya Ivashka beat Laslo Djere for the right to tussle with tournament favourite Andrey Rublev next.

Pablo Carreno Busta beat Filip Krajinovic in the final of the Hamburg European Open to lift his first ATP 500 trophy.

Spanish second seed Carreno Busta wrapped up a convincing 6-2 6-4 win over Krajinovic of Serbia in one hour and 23 minutes.

Krajinovic, who beat Stefanos Tsitsipas in the quarter-finals, had no answer to Carreno Busta's serve as he won 81 per cent (21/26) of his first-service points.

Carreno Busta broke Krajinovic's serve twice in the first set before he served out. 

Krajinovic showed more fight in the second set, but he was unable to create a break chance, and when he offered one to Carreno Busta his opponent seized it.

The victory gave world number 13 Carreno Busta, who did not drop a set in the tournament, his 17th win on clay this season.

Filip Krajinovic will take on Pablo Carreno Busta in the Hamburg European Open final on Sunday.

A memorable week for Krajinovic continued as he saw off fellow Serbian Laslo Djere 6-4 6-2 in his semi-final.

Sixth seed Krajinovic defeated Stefanos Tsitsipas in the quarter-finals and ensured he followed up on that surprise victory with a dominant display against Djere on Saturday.

The victor committed only seven unforced errors in the match, while conceding just two break points in the contest.

Second seed Carreno Busta has not dropped a set all week and kept that run going with a 7-6 (7-2) 6-3 win over Federico Delbonis.

Carreno Busta needed just under two hours to see off a battling Delbonis, with neither player offering up a single break point in a first set that went the distance.

The Spaniard won five straight points to take the tie-break and continued that momentum into the second set when he broke Delbonis twice.

Neither Carreno Busta nor Krajinovic has ever won a tournament at ATP 500 level or above.

Carreno Busta has five career titles, but all of those are at ATP 250 level, losing to Dominic Thiem in his only showpiece appearance at this level at the Rio Open back in 2017.

Krajinovic, meanwhile, has lost all three of the career finals he has reached.

"I enjoy playing here, I feel comfortable here," Carreno Busta said. "It is my most important match this year on Sunday - I need to be really focused until the end.

"[Delbonis] is a really tough player and my level was very good. I probably played better in the second set, but I continued fighting all the time."

At the Nordea Open in Bastad, Sweden, top seed Casper Ruud was comfortable as he defeated Roberto Carballes Baena 6-1 6-4 to earn a place in the final.

Ruud needed just 79 minutes to do the job, breaking Carballes Baena on five occasions. 

He has only played two matches – both comfortable wins – to reach the final after a walkover against Henri Laaksonen in the quarters.

Rising star Ruud will bid for his second ATP title of the year and the third of his career against Federico Coria on Sunday.

Coria also had a comfortable last-four tie, seeing off Germany's Yannick Hanfmann 6-2 6 -1, with the win meaning the 29-year-old reached his maiden career tour final.

"I am very happy - it is my first final," said world number 77 Coria, who beat second seed Cristian Garin in the last eight.

"I played the best tennis of my life in this match. It is amazing here in Bastad, it is beautiful."

Stefanos Tsitsipas will head into the Tokyo Olympics on the back of a disappointing quarter-final exit at the Hamburg European Open.

The world number four made a fast start to his match against Filip Krajinovic, winning the opening five games, but fell away to lose in three sets after an hour and 59 minutes.

Tsitsipas is due to represent Greece at the behind-closed-doors Games in Japan, where he will be among the medal favourites.

His racket bizarrely fell apart in the second set against Krajinovic, with Tsitsipas left clutching just the handle as the head broke off when he attempted a backhand.

Despite reaching for a replacement racket, Tsitsipas could not get the better of his 44th-ranked Serbian opponent.

Krajinovic said, according to the ATP website: "He started really well, really aggressively. I could not find my game, could not find my serve, he was overpowering me. But at the end of the first set, I started to feel better, I was going for my shots.

"It paid off in the end. I am happy to beat Tsitsipas, he is an amazing player. I always play well here, and I hope I keep playing well here."

Krajinovic advances to take on a fellow Serbian, Laslo Djere, in the semi-finals, after Djere swept to a 6-2 6-2 win over Georgian Nikoloz Basilashvili.

Spanish second seed Pablo Carreno Busta prevented a third Serbian reaching the final four, beating Dusan Lajovic 7-6 (7-4) 6-3, and he will face Federico Delbonis on Saturday.

At the Nordea Open in Bastad, Sweden, top seed Casper Ruud had his path to the semi-finals smoothed by the withdrawal of scheduled opponent Henri Laaksonen due to injury.

That walkover means Norwegian Ruud will next tackle Roberto Carballes Baena, who beat Slovakian Norbert Gombos 6-4 6-2.

Chilean second seed Cristian Garin bowed out, beaten 6-4 4-6 6-2 by Argentinian Federico Coria. Coria's semi-final opponent will be Germany's Yannick Hanfmann, a 6-4 6-3 victor over French qualifier Arthur Rinderknech.

Casper Ruud fed off the growing expectation that surrounds him as he took a convincing first step in the Nordea Open.

The 22-year-old Norwegian has rocketed from outside the top 50 to 16th currently in the world rankings in just 18 months, and he is the top seed this week in Sweden.

Such a status is all rather novel for Ruud, but he breezed to a 6-0 6-2 win over 18-year-old Danish wildcard Holger Vitus Nodskov Rune on Thursday.

That carried him through to a quarter-final meeting with Swiss player Henri Laaksonen.

Ruud is back on clay this week, having enjoyed great success on the surface already this season, reaching semi-finals of the Masters 1000 events in Madrid and Monte Carlo, while also winning a title in Geneva.

A first-round exit on the Wimbledon grass followed those positive results, so another event on clay comes as a boost.

"It is a surface I have had the most success of my career, it is great to be back here in Bastad," Ruud said after crushing Rune's hopes.

"There is a bit of extra pressure [being the top seed]. In a match like this against a fellow Scandinavian younger player, it is even more."

He added, quoted by the ATP website: "I think I was very professional in my mindset today. I played a match without any errors really from the first to the last point.

"It is a nice feeling being the top seed but also pressure. I felt great crowd support, it is nice to feel that energy."

Qualifier Laaksonen beat Elias Ymer 6-2 7-5, while third seed Fabio Fognini was bounced out of the tournament, losing 6-3 1-6 6-4 to Spain's world number 97 Roberto Carballes Baena, who will tackle Slovakian Gombos in the last-eight stage on Friday.

At the Hamburg European Open, Pablo Carreno Busta justified his standing as second seed with a 7-5 6-3 win over fellow Spaniard Carlos Taberner to reach the quarter-finals.

Stefanos Tsitsipas is the top seed this week at the tournament in Germany and won through to the last eight on Wednesday.

Others to move through the rounds in Hamburg on Thursday included Dusan Lajovic and Federico Delbonis, the latter advancing with a handy 6-3 7-6 (7-4) win over fourth seed Albert Ramos-Vinolas.

Stefanos Tsitsipas made a winning return to action as he reached the Hamburg European Open quarter-finals with victory over Dominik Koepfer in straight sets.

Having lost a five-set epic against Novak Djokovic in the French Open final, Tsitsipas crashed out in the first round of Wimbledon against Frances Tiafoe.

The Greek welcomed a return to the clay courts in Hamburg, though, as he saw off a battling Koepfer 7-6 (7-2) 6-3 in a productive workout lasting one hour and 44 minutes on Wednesday.

Tsitsipas dropped serve in the first game of the match but immediately struck back and was not broken again in the contest.

He forced plenty of break opportunities – 14 in total – and converted three over the course of the match which proved enough for victory at the ATP 500 event.

Four set points came and went for Tsitsipas as Koepfer served it out at 6-5 to force a tie-break in the opener, but it mattered little when the world number four won four consecutive points to clinch the breaker.

Koepfer led 3-2 in the second set but two consecutive breaks from Tsitsipas ended the contest and ensured he booked a tie against Filip Krajinovic in the last eight.

Sixth seed Krajinovic beat a German opponent to disappoint the home fans for a second straight day, though he needed a deciding set before seeing off veteran Philipp Kohlschreiber 7-5 4-6 6-3.

In the Nordea Open, held in Bastad, fourth seed John Millman was a casualty as he went down in three sets to big-serving qualifier Arthur Rinderknech, who had 12 aces.

There was no such drama for second seed Cristian Garín, though, as he saw off Pedro Martinez 6-3 6-3, dropping serve just once.

Daniil Medvedev is set for just the third grass-court semi-final of his ATP Tour career at the Mallorca Championships.

Medvedev, who has reached two hard-court grand slam finals, as well as winning last year's ATP Finals, has never been beyond the last four on grass. He has only done so once on clay.

The Russian will get another chance on Friday, though, against Pablo Carreno Busta.

That is his reward for beating Casper Ruud, who Medvedev acknowledged likely also does not favour the grass season.

"I don't think grass is his best surface, but in the first set he was playing top level and I couldn't get any break points," Medvedev said after beating Ruud 7-5 6-1. 

"But as soon as he started serving a bit worse and making some errors, I tried to use it as fast as I could.

"It was important to win the first set and not in a tie-break, this gives me a boost of confidence."

Carreno Busta defeated Jordan Thompson in straight sets but was not followed into the semis by either of the other Spaniards in action.

Third seed Roberto Bautista Agut was toppled by Sam Querrey, as Feliciano Lopez lost to Adrian Mannarino.

At the Viking International in Eastbourne, there is an Australian in each semi-final after wins for Alex de Minaur and Max Purcell.

De Minaur wore down Vasek Pospisil 6-4 6-4 and now faces Kwon Soon-woo, who was similarly comfortable against Ilya Ivashka.

Purcell battled past Andreas Seppi, recovering from a tough second set in which he succumbed 6-1, but must now face another Italian.

Third seed Lorenzo Sonego secured his semis spot by blasting past Alexander Bublik 6-1 7-5.

Matteo Berrettini became the first Queen's Club Championships debutant to carry off the singles trophy since Boris Becker, as the Italian landed the biggest title of his career.

The world number nine beat British hope Cameron Norrie 6-4 6-7 (5-7) 6-3 in the London showpiece match on Sunday, setting himself up ideally ahead of a Wimbledon mission later this month.

Whereas Becker was 17 when he triumphed at Queen's Club in 1985, going on to be champion at Wimbledon just weeks later, Berrettini is 25 years old and established as a leading player.

His big serve – an aspect of his game he shares with vintage Becker – proved a huge asset against Norrie as Berrettini served 19 aces and won 91 per cent of points when landing his first delivery.

Norrie could not forge a break point but did commendably well to force a deciding set in a match that lasted three minutes short of two hours.

Berrettini said he had experienced an "unbelievable week", lifting his first title at ATP 500 level, and he was blown away by the Becker link.

"If I think about his name and my name, it's crazy," he said in an on-court interview.

"I was dreaming about playing this tournament. I was watching when I was a kid and now I had the chance to lift the trophy. It's a dream come true."

Berrettini could be a threat to anyone if his serve fires at Wimbledon, and he was proud of how he fended off Norrie.

"I didn't check the numbers during the match. I knew I was serving well," said Berrettini. "I knew it was important because in the rallies this guy is dangerous. I knew I had to play my best tennis."

Berrettini said his celebrations were likely to be muted, given he is in a pre-Wimbledon bubble, predicting his team would limit his post-match treats to "probably room service and sparkling water".

There would be cause for greater cheer if Berrettini goes on a run at the All England Club, with Wimbledon due to begin on June 28. His previous best performance at Wimbledon was a run to the fourth round two years ago.

Berrettini told Amazon Prime: "I know it's going to be a really tough tournament.

"Probably all the players have extra motivation to play well there so it's going to be tough, but I have a lot of confidence."

Ugo Humbert upset the odds by overcoming Andrey Rublev to win the Halle Open title, clinching his first ATP 500-level trophy in the process.

Unseeded Humbert already claimed the scalp of Alexander Zverev earlier in the week and, having seen off Felix Auger-Aliassime to reach the final, came out on top against world number seven Rublev 6-3 7-6 (7-4).

Rublev was appearing in his eighth final since the start of 2020, though it was his first on grass. The Russian was seeking a fifth successive victory in an ATP 500 level final, yet ultimately came up short, meaning Humbert made it three wins from three in his career finals.

The 22-year-old won his first two titles – in ATP 250 events in Antwerp and Auckland – last year.

Humbert's victory took just 87 minutes, with the Frenchman winning 45 of 53 points on his first serve.

The only break of the game went Humbert's way when he struck to make it 5-3 in the first set before holding off two break points in the next game to take the lead.

Neither player offered a single break point in the second set, and it was Humbert who nosed himself in the tie-break to secure a third career triumph, becoming the first player to win the Halle Open on his debut at the tournament since Lleyton Hewitt defeated Roger Federer in 2010.

Humbert's win will also take him up six places in the ATP rankings, from 31 to 25.

Matteo Berrettini continued his impressive charge at the Queen's Club Championships as he booked a place in the final against Cameron Norrie.

Top seed Berrettini, ranked nine in the world, has not dropped a set all week.

His impressive run has seen him defeat home hopes Andy Murray and Dan Evans, with one more Briton in the shape of Norrie left to see off in his bid for glory.

Berrettini ensured he will be in the final by claiming a 6-4 6-4 triumph over fourth seed Alex de Minaur in the semi-final on Saturday.

The Italian dropped just four of his 36 points on first-serve and sent down eight aces, with De Minaur only able to force one break point in the entire contest, which he did not take.

"[Making the final] was the goal of the week and now I have one more step," said Berrettini.

"It is a great achievement, especially for the history of this tournament. I am really happy because to beat Alex, I had to play my best tennis."

Berrettini has four tour titles to his name, though this would be his first at ATP 500 level or above.

Victory would also represent the biggest win of Norrie's career – he has lost each of his three previous finals, all at ATP 250 level.

Norrie impressively eliminated Denis Shapovalov to reach the showpiece, beating the Canadian 7-5 6-3.

Shapovalov had earlier finished off a 6-3 6-4 quarter-final win over Frances Tiafoe, a match that could not be completed on Friday due to fading light.

But the second seed could not muster up another victory against a fresher Norrie.

At the Halle Open, Andrey Rublev reached his eighth final since the start of 2020, though his first on a grass court.

Rublev dropped his first set of the week but ultimately prevailed with a 6-1 3-6 6-3 semi-final victory over Nikoloz Basilashvili.

The Russian has won his last four finals at ATP 500 level and will seek a fifth on Sunday.

"It's my first final on grass and in Halle," he said. "I think I can play on every surface and I will try my best again.

"I had good opportunities to break Basilashvili in the second set, some quite easy forehands and I stressed a little showing my emotions. 

"I then came back and stayed calm, until the last game. But I won."

Rublev will take on unseeded Ugo Humbert, who held his nerve to edge a thriller against Felix Auger-Aliassime, winning 6-4 3-6 7-6 (7-5).

Humbert beat Alexander Zverev earlier in the week and has had to win a deciding set in all four rounds, while the beaten Auger-Aliassime had previously seen off Roger Federer as part of a dramatic event.

Frenchman Humbert won each of his first two career finals, which both took place last year in ATP 250 events.

Top seed Matteo Berrettini has his sights set on the Queen's Club Championships title after beating Dan Evans in the quarter-finals.

After a delay of more than four hours because of rain in London, Berrettini overcame Evans 7-6 (7-5) 6-3 to reach his third ATP grass-court semi-final.

The Italian hit 13 aces and won 81 per cent of his first-serve points against Evans to set up a last-four clash with Alex de Minaur. 

Berrettini improved his win-loss record to 24-6 for the season and laid out his ambition to walk away from the tournament with the trophy.

"I didn't serve that well, but I was returning well and I just played better in the last few points of the tie-break," he said.

"After that, I felt more confident. The conditions were really tough, windy and cold, so I took time to adapt a little bit. I am pretty happy with my performance.

"The court condition was really good. I expected slippery conditions, but it was like yesterday.

"I came here to win the tournament, that is my goal. Now I am two steps away. I am happy with the way I am playing, and my mental attitude is really good."

Up next for Berrettini is Australian De Minaur, who came from behind to defeat Marin Cilic 3-6 6-3 6-4.

The 22-year-old won 73 per cent (22/30) of his second-serve points and saved six of the seven break points he faced as he moved to 16-12 for the season.

In the battle of the British players, Cameron Norrie beat Jack Draper 6-3 6-3, while Denis Shapovalov was leading Frances Tiafoe 6-3 when their match was suspended due to fading light. They will resume on Saturday.

At the Halle Open, Andrey Rublev reached his sixth ATP Tour semi-final of the year thanks to a 7-6 (7-4) 6-2 win over 2011 champion Philipp Kohlschreiber.

"I am happy with my performance to reach the semi-finals for the first time," Rublev said. "The first set was really tough. He was 3-0 up in the tie-break and I came back, which was the key.

"After the first set, I think he mentally went down and I was pumped up. I hit a couple of good returns in the first game of the second set."

Russian Rublev will face Nikoloz Basilashvili in the last four after the Georgian defeated Lloyd Harris 6-4 7-6 (7-5). 

In the day's other quarter-finals, Felix Auger-Aliassime beat Marcos Giron 6-3 6-2 and Ugo Humbert overcame Sebastian Korda 6-2 6-7 (5-7) 6-4.

Top seed Matteo Berrettini beat Andy Murray to reach the quarter-finals at Queen's Club and Ugo Humbert upset Alexander Zverev at the Halle Open on Thursday.

Murray, a five-time champion at Queen's, was beaten 6-3 6-3 by Italian Berrettini as the three-time grand slam champion struggled a day on from being given a Wimbledon wildcard.

The former world number one beat Benoit Paire in his first ATP Tour singles match since March on Tuesday, but the 34-year-old revealed he is still being troubled by a groin injury after his loss to Berrettini and knows he must raise his game.

Murray said: "I actually felt my movement was actually quite good for both of the matches. My tennis today was not very good. That's the thing that I'll need to improve the most.

"Then there is still a slight niggle in the groin, so [I have] to try to get rid of that discomfort between now and Wimbledon. I need to be playing points, basically. I played two sets in preparation for this event.

"I do feel like I genuinely have been hitting the ball well in practice, but then like today when you're under a bit more pressure and stuff and you're having to make very split-second decisions when you're on the court, if the guy is serving 140 miles an hour, like, it's difficult to prepare for that."

Dan Evans made history earlier in the day, getting the better of Adrian Mannarino 6-4 7-6 (9-7).

With Jack Draper and Cameron Norrie having already progressed, Evans' win ensured there will be three Britons in the singles quarter-finals for the first time in the Open Era.

Feliciano Lopez will not retain his title in London after the Spaniard went down 6-2 6-3 to second seed Denis Shapovalov. Spanish veteran Lopez won in 2019, with last year's tournament cancelled due to the pandemic.

There will be no glory on home soil in Halle for German Zverev, who was taken out 7-6 (7-4) 3-6 6-3 by unseeded Frenchman Humbert.

Humbert has now beaten a top-10 player on every surface, with Zverev serving 20 aces but bowing out after his 22-year-old opponent claimed the only break of the final set.

Sebastian Korda battled past Kei Nishikori 2-6 6-3 7-5 in Halle, while Lloyd Harris also moved into the last eight at Lukas Lacko's expense.

Andy Murray had to hold back the emotion as he celebrated a winning return to the ATP Tour at Queen's.

Murray had hip surgery in 2019 and had not won a grass-court game since 2018, with last year's season having been cancelled due to the coronavirus pandemic.

Having struggled with a groin injury, the 34-year-old Scot last played in March, yet showed flashes of his old self in his 6-3 6-2 victory over Benoit Paire, having taking up a wildcard into the pre-Wimbledon tournament.

It was an emotional moment for Murray, who said: "Look, I love playing tennis."

The five-time champion was fighting back the tears as he continued: "Obviously, competing is why you put in all the hard work.

"The last few years, I've not got to do that as much as I would have liked so, yeah it's just great that I'm out here and able to compete again.

"The body is old, but I did quite well today in terms of my movement.

"It's my first match on grass in three years and I've only played three or four practice sets in the build-up to this, so I didn't know exactly how I was going to play or feel – but I think for a first match it was good."

Murray will face top seed and world number nine Matteo Berrettini, who defeated Stefano Travaglia 7-6 (7-5) 7-6 (7-4).

British number one Dan Evans beat Alexei Popyrin, while fourth seed Alex de Minaur also progressed to round two, having come from behind against Laslo Djere. Second seed Denis Shapovalov overcame Aleksandar Vukic.

Tuesday's results mean, for the first time since 2005, four British players have won at Queen's, with Cameron Norrie and Jack Draper having gone through on Monday.

Meanwhile, after losing to Stefanos Tsitsipas in the French Open quarter-finals, world number two Daniil Medvedev crashed out of the Halle Open in the first round.

Jan-Lennard Struff was his conqueror, claiming a 7-6 (8-6) 6-3 triumph, which the German labelled as "the biggest win of my career."

There was better luck for third seed Alexander Zverev, though he did need three sets to see off Dominik Koepfer 6-4 3-6 6-3, just four days after facing Tsitsipas in the Roland Garros semi-finals.

Ugo Humbert awaits Zverev, while Felix Auger-Aliassime beat Hubert Hurkacz to tee up a tie with Roger Federer. World number seven Andrey Rublev got the better of Karen Khachanov.

Roger Federer returned to action at the Halle Open on Monday and won his first match on grass since the 2019 Wimbledon final.

Federer has endured two torrid years on the ATP Tour, missing most of 2020 due to double knee surgery.

The 20-time grand slam champion had then been limited to six matches this season heading into this week.

Having finally found some momentum at the French Open, Federer withdrew from his fourth-round match and explained: "It's important that I listen to my body and make sure I don't push myself too quickly on my road to recovery."

But the Swiss great was fit to finally step back out on a grass court for the first time since coming up short against Novak Djokovic at the All England Club.

And it was a winning return as Federer battled past Ilya Ivashka 7-6 (7-4) 7-5 in Germany.

Ivashka squandered two break point opportunities early in the opener and was quickly on the back foot after the set went to a tie-break, saving three set points but not a fourth.

Federer stayed patient in a second that stayed on serve initially, belatedly piling on the pressure to break in the final game having earlier passed up a match point at 5-4.

Fifth seed Federer was the only seed to win on Monday, however, as Sebastian Korda upset Roberto Bautista Agut in straight sets and David Goffin gave Corentin Moutet a walkover.

There was a standout shock at the Queen's Club Championships, too, as talented teenager Jannik Sinner was pipped by home hopeful Jack Draper 7-6 (8-6) 7-6 (7-2).

Draper's compatriot Cameron Norrie joined him in the last 16, battling back to beat Albert Ramos-Vinolas in three.
