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.

Alex De Minaur claimed the first grass-court title of his career with a hard-fought three-set victory over Lorenzo Sonego in the Viking International final.

De Minaur lost the first set against his Italian opponent, who reached a career-high ranking of 26 earlier this month, but the Australian fought back to prevail 4-6 6-4 7-6 (7-5).

Having forced a decider, it was De Minaur who had the most left in the third-set tie-break, which decided an entertaining contest that lasted two hours and 40 minutes.

It marked De Minaur's second title of 2021 following his success at the Antalya Open back in January.

Prior to Saturday, all four of De Minaur's ATP titles had come on hard courts.

However, an excellent backhand return of a second serve set him up for a forehand smash to clinch a triumph that should give him great confidence heading into Wimbledon.

De Minaur starts his campaign at the All England Club on Monday with a testing opening clash against Sebastian Korda while Sonego faces Pedro Sousa.

Speaking at the presentation, De Minaur paid tribute to Sonego, who recently lost his grandmother.

"Everyone should congratulate Lorenzo for an incredible week. Everyone should be scared of you at Wimbledon next week," said De Minaur.

"It's been a long week, I've played some great tennis, I've managed to pull through a very tough win.

"Hopefully I can keep it going through Wimbledon, I can't wait to go there next week."

Daniil Medvedev made light work of sealing his first grass-court title, as he defeated Sam Querrey in straight sets at the Mallorca Championships.

The world number two was playing in his first final on grass, and took just 63 minutes to win 6-4 6-2 and warm up for Wimbledon in emphatic fashion.

It brings up Medvedev's second title of the season and his 11th in total, though he had failed to progress beyond the quarter-finals in his last five tournaments since winning in Marseille in March.

Medvedev suggested he was clicking into gear after his win over Pablo Carreno Busta on Friday, and he backed up his point on Saturday, cruising to victory without offering up a single break point.

The 25-year-old broke world number 60 Querrey – seeking his first ATP Tour title since 2017 – on three occasions, and an ace, his 10th of the match, sealed victory.

Like at the French Open, Medvedev heads to Wimbledon as the second seed. He is the same half of the draw as 20-time grand slam champion Roger Federer, and has a first-round encounter with Jan-Lennard Struff, who knocked the Russian out of the Halle Open last week.

Daniil Medvedev reached the first grass-court final of his career as he saw off Pablo Carreno Busta at the Mallorca Championships.

Medvedev, the top seed, had to come from a set down against his Spanish opponent, winning 3-6 6-3 6-2 to tee up a showdown against Sam Querrey.

The world number two has won 10 ATP Tour titles, but they have all come on hard courts.

"I know that I can play well on grass," said Medvedev, who followed up a quarter-final run at Roland Garros with a first-round defeat to Jan-Lennard Struff at the Halle Open.

"Unfortunately we don't have that many tournaments, only one ATP 500 and one grand slam. It's going to be a special feeling [if I] win my first title on grass.

"I still don't have one on clay, even if I have one final. Adding these titles, especially on different surfaces, can help your confidence and it’s just a great thing for your career."

World number 13 Carreno Busta had looked sharp in successive straight-set wins en route to the semi-finals, and started Friday's encounter in good form.

He had not dropped serve across the first four sets of his campaign in Mallorca and extended that streak by saving three break points in the opening set.

However, Medvedev – who has been drawn in the same half as Roger Federer at Wimbledon – rallied and served out the one-hour, 56-minute victory with an ace.

Querrey, meanwhile, will be going for his first ATP Tour title since 2017 after he cruised to a 6-4 6-3 win over unseeded Adrian Mannarino.

Another player who is hunting for his first Tour triumph on grass is Alex de Minaur, who defeated Soon Woo Kwon 6-3 7-6 (7-2) to progress to the Viking International final.

The world number 18 has won four hard-court titles and will go up against Lorenzo Sonego for the crown in Eastbourne.

Sonego beat De Minaur's compatriot Max Purcell 6-1 3-6 6-1. The Italian triumphed at the Sardegna Open in April.

Dominic Thiem will seek the advice of a specialist in Barcelona after suffering an injury scare ahead of Wimbledon next week.

Number two seed Thiem retired due to a wrist injury when 5-2 up in the opening set against Adrian Mannarino in the Mallorca Championships on Tuesday.

An MRI conducted at a Mallorca hospital was inconclusive, so the US Open champion will now undergo further tests.

In an update on Wednesday, Thiem wrote on social media: "Yesterday during the match I had a problem with my wrist.

"I went immediately to do an MRI at the hospital in Palma de Mallorca. The results weren't that clear and I have decided to go to Barcelona to check with a specialist.

"I hope I can get the results and a clear diagnosis in the next days."

The ATP 250 event continued without him in Mallorca, as Roberto Bautista Agut moved into the quarter-finals with a 6-3 7-5 triumph over Italian Stefano Travaglia.

More Spanish success on home soil arrived as Pablo Carreno Busta won 6-4 6-4 against Jiri Vesely.

In the doubles, Novak Djokovic and Carlos Gomez-Herrera saw off top seeds Marcel Granollers and Horacio Zeballos to reach the last four in that competition.

Djokovic appears to be enjoying himself as he continues to prepare for Wimbledon, saying: "This was a huge win for us, beating one of the best doubles players in the world after losing the first set.

"We are having a lot of fun on the court. I thought we played well even though we lost the first set."

There was a major upset at the Viking International in Eastbourne, meanwhile, with number one seed Gael Monfils suffering a shock last-16 defeat to Australia's Max Purcell – ranked number 283 in the world.

Purcell, who is only in the tournament as a lucky loser, claimed a huge 6-4 5-7 6-4 win in a battle lasting over two hours.

Monfils fired down 16 aces and fought back after being within two points of defeat in the second set but was ultimately beaten and has not made an ATP quarter-final since February 2020.

"It feels unbelievable," said Purcell. "I thought I'd come out and have a go. 

"I've struggled to get into any singles events over the past nine months and primarily played doubles, so to get on a run here, on my favourite surface, is great."

Purcell will take on Andreas Seppi – a comfortable winner over Emil Ruusuvuori – in the last eight.

While Monfils crashed out, there was less drama for the second and third seeds. 

Alex de Minaur won 6-3 6-4 against home hope Liam Broady, while Lorenzo Sonego was a 6-4 6-2 victor in his contest with John Millman.

There were no shocks at the Stuttgart Open on Tuesday as Marin Cilic and both seeds advanced.

The grass-court swing got under way with four main-draw matches but little drama in Germany.

One-time Wimbledon finalist Cilic staved off the only two break points he faced against wildcard Rudolf Molleker and seized all five opportunities of his own.

A 7-5 6-3 win was enough to set up a second-round meeting with fifth seed Nikoloz Basilashvili, who beat Dustin Brown in the top half of the draw.

The defeated pair were the only home hopefuls in action, while number six seed Ugo Humbert and Lloyd Harris each also progressed.

Sebastian Korda won the first ATP Tour title of his career with a straight-sets defeat of Marco Cecchinato in the Emilia-Romagna Open final on Saturday.

Korda became the first American man to be crowned a champion on clay in Europe for 11 years, beating the Italian wildcard 6-2 6-4 in Parma.

The unseeded 20-year-old son of former world number two Petr Korda did not drop a set this week and will head to the French Open with his confidence sky-high.

Korda won 82 per cent of points behind his first serve and broke three times to get the better of Cecchinato at the President Tennis Club.

The Florida native took just an hour and 15 minutes to become the first American man since Sam Querrey in Belgrade back in 2010 to win a title in Europe on this surface.

His victory ensured the Kordas are the third father-son duo to win ATP Tour-level singles titles in the Open Era, emulating Ramanathan Krishnan and Ramesh Krishnan, and Phil Dent and Taylor Dent.

World number 63 Korda will face Spaniard Pedro Martinez in the first round at Roland Garros next week.

Novak Djokovic will head to the French Open on the back of claiming the singles title at the Belgrade Open after battling past Alex Molcan in the final.

The world number one did not have it all his own way against the world number 255, with the first set featuring just three service holds.

But Djokovic claimed four breaks to Molcan's three to take the opener and did not let his advantage slip in front of his home crowd.

He negotiated a similarly tricky second set to prevail 6-4 6-3, with attention now turning to the second grand slam of the year after Djokovic won the Australian Open back in January.

After a resilient performance in the first set as he twice came back from a break down, Djokovic was able to enjoy a slightly less frenetic path to victory in the second.

He broke down a more obdurate Molcan for a 4-2 lead, only for the Slovak to hit straight back.

But Djokovic was not to be denied and immediately claimed another break, which he consolidated to delight his adoring public.

Victory in what was Djokovic's first final on home soil since 2011 means he now has 83 ATP singles titles to his name, with three of them coming at this event.

It also caps a positive period of preparation for a tilt at a second French Open title, with Djokovic having reached the final in Rome this month only to lose to Roland Garros favourite Rafael Nadal.

Nadal and Djokovic could meet in the semi-finals this year in Paris, where the Serbian was thrashed by the King of Clay in three sets in the 2020 final.

Djokovic will start his campaign to add to his 2016 French Open success when he faces Tennys Sandgren in the first round.

Novak Djokovic survived a second-set fightback from Andrej Martin to seal his place in the final of the Belgrade Open on Friday.

The world number one looked well placed to cruise to victory after taking just 38 minutes to win the first set 6-1, but qualifier Martin hit back in the second to force a decider.

Djokovic swiftly regained composure, though, with a bagel settling the contest 6-1 4-6 6-0 in his favour, and he will now have the backing of his home crowd as he looks to clinch his third Belgrade Open title and warm up for the French Open in style.

"I'm super excited to play in front of a Serbian crowd. This is my home town," said Djokovic, who previously won at the event in 2009 and 2011.

"I'm always excited, but also nervous, coming out on the court and playing in front of my home crowd. It's a very unique feeling. You feel a lot of pressure and expectations. But I'm just happy to fight for a trophy.

"I thought I started and finished the match really well, so I'll try to take those positive feelings into tomorrow's final. I also had some letdowns in concentration towards the end of the second set, and I'll try to correct those mistakes for tomorrow."

Standing in the way of a second title of the season for 34-year-old Djokovic is another qualifier, Slovakian Alex Molcan, who came from behind to beat Federico Delbonis 4-6 6-4 6-4.

At the Emilia-Romagna Open, Sebastian Korda, who has yet to drop a set this week, triumphed in an all-American semi-final contest, beating Tommy Paul 6-3 6-3 to reach his second Tour-level final.

Korda's win sets up a final against Italian Marco Cecchinato, who is aiming for his fourth career singles title after overcoming Jaume Munar 7-6 (7-2) 1-6 6-1.

Novak Djokovic felt he produced his best performance of the year in breezing past Federico Coria at the Belgrade Open for a milestone victory.

World number one Djokovic needed a little under an hour to beat Coria 6-1 6-0 on Thursday and set up a semi-final with Andrej Martin on home soil.

The victory moves the 34-year-old above Argentine great Guillermo Vilas for the fifth-most victories in the Open Era with 952.

He is 70 wins adrift of fourth-placed Rafael Nadal (1,022). Ivan Lendl (1,068) is third, behind Roger Federer (1,243), with Jimmy Connors holding the record of 1,274 wins.

Djokovic won 53 of the 75 points played against Coria and dropped just one game to remain on course for a third crown in Serbia ahead of the French Open.

"It was a great display," Djokovic said in his on-court interview. "It's probably one of the best matches, if not the best match, I played this year. I felt fantastic from the first point.

"It was the first time that I played against Coria and I tried to impose an aggressive style from the very beginning and not allow him to have too much time to play around. I played a phenomenal second set, really flawless.

"It's not always possible to play like this. But I think this definitely helps me feel better on the court. I think everything worked perfectly for me today."

Martin awaits Djokovic in the last four after the world number 119 recovered from a set down to beat Dusan Lajovic 3-6 6-3 6-4.

Alex Molcan remains in the hunt for a shock triumph in Belgrade, meanwhile, after beating Fernando Verdasco 6-2 6-0 to set up a showdown with Federico Delbonis.

Eighth seed Delbonis advanced to his second semi-final of the season following Roberto Carballes Baena's withdrawal through illness.

At the Emilia-Romagna Open in Parma, Sebastian Korda eliminated Yoshihito Nishioka to set up an all-American semi-final with Tommy Paul, who took down Jan-Lennard Struff with a 6-2 6-4 victory.

Richard Gasquet was another seeded player to fall as he lost 6-1 6-1 to Jaume Munar, with the Spaniard now set to take on Italian wild card Marco Cecchinato – a straight-sets winner against lucky loser Norbert Gombos – for a place in the final.

World number one Novak Djokovic will face Mats Moraing in the second round of the Belgrade Open on Tuesday.

Moraing, who is ranked 252 places below Djokovic, beat Egor Gerasimov 4-6 7-6 (9-7) 7-5 in a gruelling encounter on Monday.

Djokovic is seeking his 83rd Tour-level title as he warms up for the French Open, the main draw of which begins on May 30.

Fellow home favourite Dusan Lajovic, the highest seed to compete on day one, will meet Jeremy Chardy next after beating Ricardas Berankis in straight sets.

Eighth seed Federico Delbonis required three sets to see off Lukas Klein, while seventh seed Miomir Kecmanovic – another Serbian in the draw – was beaten 6-3 6-2 by Pablo Cuevas.

Veteran Fernando Verdasco set up a contest with Adrian Mannarino after an impressive 7-5 6-2 win over Lucas Pouille.

At the Emilia-Romagna Open in Parma, all of Monday's play had to be cancelled due to persistent rain.

Fifth seed Richard Gasquet is in action on Tuesday.

Federico Coria and Jeremy Chardy, along with Serbian Pedja Krstin, progressed into the second round in Belgrade on Sunday.

Coria came from a set down to win 4-6 6-2 6-0 in the first-round match in the Serbia Open against ATP Tour debutant Marko Topo.

Chardy overcame Tennys Sandgren 6-4 6-2. The Frenchman started the season well, and managed two semi-final runs, but has been out of form in recent competitions and was knocked out in the first round at the Madrid Masters earlier this month.

Meanwhile, Pedja Krstin made home advantage count against Kwon Soonwoo.

The trio will be joined in the second round by top seed and world number one Novak Djokovic, who received a first-round bye and is in the hunt for his third title in Belgrade.

At the Parma Open, American Tommy Paul reeled off a 7-5 6-4 win over Stefano Travaglia, and Flavio Cobolli beat Marcos Giron 3-6 7-6 (8-6) 7-6 (7-4).

Stefanos Tsitsipas teed himself up for the French Open in dominant fashion as he claimed his second title of 2021 with a straight-sets win over Cameron Norrie at the Lyon Open. 

Tsitsipas looked sharp throughout the week in central France and was in clinical form on Sunday, pouncing on some minor mistakes from Norrie to triumph 6-3 6-3. 

Norrie was by no means an easy opponent, but five double faults handed Tsitsipas an edge he duly made the most of. 

This year's Monte Carlo champion had to claw back three break points in the opening game of the match but was firmly in control from then on. 

A break to make it 5-3 enabled the Greek to serve for the first set – an opportunity he took at the first time of asking – and another clinical break put him 4-3 up in set two.  

Tsitsipas' third and final break came on the second match point on offer, with Norrie overhitting a forehand to seal the world number five's 33rd Tour win of the season.  

Having dropped just one set throughout his run this week, Tsitsipas will now switch focus to Roland Garros, where he reached the semi-finals in 2020.  

"I felt in a good shape from the beginning of the tournament, felt like things were going my way," he said in a post-match interview.  

"I'm proud of today's match. I knew it would be a difficult one against Cameron who has played great this week, winning against good players and showing what his left hand can do on clay. I had to handle the nerves and I'm proud of my performance and the way I stayed focused.  

"It's about getting there [Paris] as early as possible, getting in practice and getting in shape for the big Parisian grand slam which I adore and love. Hopefully, something good can come out of it." 

Stefanos Tsitsipas was happy to be kept "humble" as he needed three sets to defeat teenager Lorenzo Musetti in the Lyon Open semi-finals.

The world number five won his first ATP Masters 1000 title in Monte Carlo and reached the final in Barcelona before cruising into the last four in France without dropping a set.

However, he was forced to come from behind to beat Musetti 4-6 6-3 6-0 on Saturday to set up a showdown with Cameron Norrie.

Musetti, who broke into the top 100 for the first time this year after losing to Tsitsipas in the semi-finals in Acapulco, broke at 2-2 in the opening set as he caused havoc with drop shots.

It was not until Tsitsipas moved 5-3 ahead in the second set that the Italian's resistance finally seemed to break as he failed to win another game.

"It was important I had a match like this," Tsitsipas said. "It makes me stay humble and focus on some detailed things I can potentially improve and get better at on clay.

"I had to stay calm. It was difficult to be a set down and have to kind of refresh myself and come anew in the second set. He was still putting [in] a lot of work and making me work for every single point. It wasn't easy."

Tsitsipas will contest the final against Norrie, who got better as the day wore on across his quarter-final and semi-final matches.

Norrie concluded a 6-3 3-6 6-3 win over Arthur Rinderknech before dispatching eighth seed Karen Khachanov 6-1 6-1 in superb fashion.

"Everything was working well: serving well, returning well, anticipating the ball well," said the 25-year-old, who reached his second Tour final at this year's Estoril Open.

"I came forward when I needed to and was aggressive with good depth. It was nice to come through like that.

"I had a tough loss in my last final so it's nice I can get another opportunity so soon. It's going to be tough against Stefanos. He's in the zone as well, so it's going to be an interesting final."

Stefanos Tsitsipas insists it must be purely business when he tackles Italian teenager and fellow tennis artisan Lorenzo Musetti in the Lyon Open semi-finals.

Ahead of a tilt at the French Open, for which he is among the favourites, world number five Tsitsipas has been tuning up his game at this week's ATP 250 tournament.

The Greek star was sharp in posting a 6-3 6-4 win over Japan's Yoshihito Nishioka, and 19-year-old Italian Musetti awaits him on Saturday.

Tsitsipas dropped just four games when he crushed Musetti in an Acapulco semi-final in March, but he senses more of a threat this time from the exciting youngster.

"We played in different conditions. Acapulco was a hardcourt match and with altitude," said Tsitsipas, speaking on Amazon Prime. "The conditions here are different. He's someone who enjoys playing on clay.

"We share a similar game style I think with a one-handed backhand, which is beautiful to see, but tomorrow it's going to be serious business I knew he can play good on this surface. I know he can elevate his game, so it's important for me to be in the semi-finals."

Musetti overcame Slovenian Aljaz Bedene 6-3 7-6 (7-2) in their quarter-final, scrambling through a chaotic second set in which he trailed 5-2 at one stage but then reeled off four straight games, only to fail to serve out.

Thankfully for the youngster, he pulled through the tie-break.

"It was a crazy end," said Musetti. "I was 6-5 up, and at 30-30 played a really bad volley and hit an underarm serve. Sometimes I go out of my mind. I am really proud of myself as I was 2-5 down in the second set and I stayed focused. I tried to play each point at my best."

Russian Karen Khachanov marked his 25th birthday with a 6-1 7-6 (7-3) win over Frenchman Richard Gasquet, veteran doyen of the single-handed backhand.

Khachanov faced a wait to learn who he must face in the semi-finals, however, with Cameron Norrie and Arthur Rinderknech level at one set all overnight, after rain forced an early end to play.

At the Geneva Open, Norway's Casper Ruud will tackle Canadian Denis Shapovalov in Saturday's final.

Ruud saw off Spaniard Pablo Andujar 6-3 6-2, while Shapovalov earned a 6-4 7-5 win against Uruguayan qualifier Pablo Cuevas.
