Federico Delbonis and Laslo Djere crashed out of the Generali Open in the first round on Tuesday.

Fifth seed Delbonis and sixth seed Djere were the highest-ranked players in action on day two, but both fell to surprise defeats.

Delbonis, a recent semi-finalist at the Hamburg European Open, was convincingly beaten 6-2 6-4 by Arthur Rinderknech.

Frenchman Rinderknech fired down 10 aces and was only broken once in the contest.

Djere, meanwhile, put up more of a fight but ultimately succumbed to Daniel Altmaier, who won 4-6 6-3 6-3 in a battle lasting two hours and 10 minutes.

World number 50 Djere had also made the semi-finals in Hamburg and followed that up with another run to the last four at the Swiss Open Gstaad.

But his run of form came to an end as German Altmaier – who himself enjoyed a semi-final run in Croatia last week – booked a last-16 tie meeting with Marco Cecchinato after breaking Djere on six occasions.

Cecchinato had beaten Radu Albot in straight sets to reach the next round while qualifier Jozef Kovalik saw off Jaume Munar with a 6-4 6-4 victory.

The top four seeds, including number one Casper Ruud, will begin their campaigns at the ATP 250 event in Kitzbuhel on Wednesday.

Pedro Martinez outlasted Lucas Pouille to set up a second-round clash with fellow Spaniard Roberto Bautista Agut at the Generali Open.

World number 97 Martinez came through Monday's longest match, which lasted two hours and 43 minutes, as a 6-3 6-7 (4-7) 6-4 winner.

Mikael Ymer, who reached the quarter-finals of last week's Swiss Open Gstaad, is also through to the second round in Austria after battling past Pablo Cuevas 6-3 7-5.

Qualifier Jozef Kovalik will face Jiri Vesely for a place in the quarter-finals, meanwhile, after beating ninth seed Jaume Munar in straight sets.

Also through on Monday was lucky loser Carlos Taberner, who took advantage of his second chance by battling from a set down to overcome Thiago Seyboth Wild 3-6 6-3 6-2.

Carlos Alcaraz won his first of possibly many ATP Tour titles on Sunday with an emphatic victory over Richard Gasquet at the Croatia Open. 

The 6-2 6-2 win in Umag meant 18-year-old Alcaraz became the youngest tour-level champion since Kei Nishikori won at Delray Beach in 2008, also aged 18.

Despite his tender years, seventh seed Alcaraz was too hot to handle for Gasquet, the highly rated Spaniard cruising past his significantly more experienced opponent in one hour and 17 minutes.

"I had a lot of good moments in this tournament. I beat five great tennis players," Alcaraz told atptour.com.

"I think that I grew up a lot in this tournament and I keep a lot of experience from this tournament. It's going to be useful for the future."

Gasquet, who needed more than three hours to overcome Daniel Altmaier in the last four, was hoping to win his first tour title since 's-Hertogenbosch in 2018.

"It was tough for me to play [with] full intensity. I had a tough match yesterday. It was tough, and especially with a guy like Carlos, who is playing really fast with a lot of energy and spin," Gasquet said.

"He’s playing unbelievable. He’s only 18 and of course he has a great future and I just couldn’t play at his level and his intensity.

"That was the key of the match and he didn't lose a point. He played well, very solid. He's a great player."

Casper Ruud secured back-to-back titles by beating Hugo Gaston in straight sets to be crowned Swiss Open Gstaad champion on Sunday.

Ruud won the Nordea Open last weekend and added a fourth ATP Tour title of his career with a 6-3 6-2 defeat of Frenchman Gaston.

The Norwegian took his tally of tournament victories on clay this year to three, having also won the Geneva Open in May, and the 22-year-old will rise to ninth spot in the ATP Race To Turin on Monday.

Ruud saved nine of the 10 break points earned by first-time ATP Tour finalist Gaston, who only won 51 per cent of points behind his first serve.

Gaston, who had never been beyond the second round at an ATP Tour event before this week, was broken twice in each set as the 20-year-old was unable to halt Ruud's brilliant run on clay.

Left-hander Gaston broke straight back after Ruud went 3-1 up in the opening set but failed to back that up with a hold.

Ruud had as many as 16 break-point opportunities but got the job done in an hour and 34 minutes.

World number 30 Cameron Norrie has claimed his maiden ATP title after defeating Brandon Nakashima in straight sets in the final of the Los Cabos Open on Saturday.

British top seed Norrie triumphed 6-2 6-2 in one hour and 23 minutes as he marks another milestone in his career-best season.

Norrie, 25, now has the most wins on the ATP tour this year, going past world number one Novak Djokovic with 35.

The 19-year-old American could not handle Norrie's first serve, while the Briton converted five of his eight break points.

Norrie served for the match with Nakashima pressing him in a tight final game but the top seed rounded out a breakthrough win.

Norrie won 21 of 29 points on his first serve, going at 72 per cent, with Nakashima breaking him once.

Hugo Gaston is one win away from securing his maiden ATP Tour title, but he must overcome in-form Casper Ruud at the Swiss Open Gstaad.

Gaston, ranked 155th in the world, booked his place in his first tour-level final with a 3-6 6-3 6-3 victory over Laslo Djere of Serbia on Saturday.

The 20-year-old had never advanced past the second round at an ATP Tour event before this week. He has now won three matches in a row in a third set.

"I tried to take more time with my game," Gaston said. "I made a lot of mistakes in the first set, so I tried to change my game. My serve was better in the second and third set.

"I am really happy to be in the final. It is going to be a good match, but I will try to enjoy [this] moment."

Ruud, meanwhile, enjoyed a rather more straightforward procession in his semi-final, with world number 249 Vit Kopriva little match for the 22-year-old Norwegian.

The world number 14 needed just 74 minutes to win 6-3 6-0, reaching his second final in as many weeks following his success in Bastad.

Ruud has won 23 clay-court matches already in 2021 and is in the hunt for his fourth career title.

Top seed Denis Shapovalov's Swiss Open Gstaad campaign came to an abrupt end as Vit Kopriva provided a second-round shock to eliminate the Wimbledon semi-finalist.

The world number 10, who has recently been praised by both Roger Federer and Rafael Nadal, took the first set 6-2 with ease before Kopriva, making his ATP Tour debut this week, emphatically fought back 6-3 6-2 to secure a memorable comeback victory.

Number three seed Casper Ruud battled past Dennis Novak 6-4 7-6 (7-5), while Benoit Paire, who only had two ATP wins in 2021 before the Hamburg European Open last week, was 6-4 to the good before Tallon Griekspoor was forced to retire due to injury.

Ruud, who has already won two ATP events in 2021 and three in his career, will now meet sixth seed Paire in the quarter-final stage.

But eighth seed Feliciano Lopez did not enjoy similar success as the world number 96 Mikael Ymer fought past the Spaniard to win 6-7 (6-8) 7-6 (9-7) 6-4 and set-up a quarter-final clash with Kopriva.

At the Umag Open in Croatia, third seed Filip Krajinovic breezed past Radu Albot to record a 6-4 6-2 win.

Krajinovic's countryman and number two ranked player Dusan Lajovic also went through with a 7-5 6-4 win against Bernabe Zapata Miralles.

Roberto Bautista Agut crashed out to Arthur Rinderknech in the second round of the Swiss Open Gstaad on Wednesday, while fifth seed Federico Delbonis also failed to progress.

Rinderknech, who is ranked exactly 100th in the world, picked up the biggest win of his career in style as he dispatched of second seed Agut with a comfortable 6-2 6-4 victory

In another upset, world number 155 Hugo Gaston laid down an early marker with a first-set demolition of Delbonis, who lost out to eventual winner Pablo Carreno Busta in the Hamburg European Open semi-finals last week, before he triumphed in three sets, 6-0 6-7 (2-7) 7-6 (7-3).

Fourth seed Cristian Garin cruised past Marc Polmans 6-3 6-0 to wrap the match up in less than an hour and seal his fifth ATP quarter-final of 2021.

Another semi-finalist in Hamburg, Laslo Djere survived a second-set scare to eliminate Zizou Bergs with a 6-2 4-6 6-2 win, which sets up a last-eight tie with Rinderknech.

At the Croatia Open in Umag, fourth seed Richard Gasquet battled past qualifier Alessandro Giannessi to secure a 7-6 (7-4) 6-4 victory.

Top seed Albert Ramos-Vinolas also progressed, winning 7-5 6-4 to eliminate Duje Ajdukovic on his home turf.

Fresh off the back of semi-final appearances at the Hamburg European Open, Federico Delbonis and Laslo Djere coasted through their respective first-round matches on the second day of the Swiss Open Gstaad, which included no upsets at the round-of-32 stage.

Delbonis, who is seeded fifth and lost to eventual winner Pablo Carenno Busta last week in Hamburg, cruised to a 6-3 6-3 victory against Leandro Riedi as the Swiss player struggled to make home advantage count.

Seventh seed and loser of the other semi-final in Germany last week, Djere continued his good form and wasted no time in thrashing Brazilian Thiago Seyboth Wild 6-4 6-3.

The other game on day two saw Dennis Novak dispatch of Kacper Zuk 6-4 6-4 and that straight-sets victory means the Austrian will next face the number three seeded player Casper Ruud, who won the Nordea Open last week to secure his third ATP title and second of 2021.

Alongside Ruud, the three other top four seeds - Denis Shapovalov, Roberto Bautista Agut and Cristian Garin - will now enter the draw, after benefiting from byes in the first round of the competition.

There was a surprise at the Croatia Open in Umag, though. Fifth seed Aljaz Bedene went down 6-1- 6-4 to Marco Cecchinato, who will now challenge fellow qualifier Damir Dzumhur to set up a potential quarter-final clash with Richard Gasquet if the Frenchman makes it through his round-of-16 tie.

Benoit Paire made a strong start as the Swiss Open Gstaad got under way on Monday.

Number six seed Paire was a 6-3 7-6 (7-2) winner in his first-round match against Jozef Kovalik.

The Frenchman was not broken in the match, saving all eight of the break-point opportunities he offered up to Kovalik during a competitive 85-minute contest.

Paire's win follows a quarter-final appearance at the Hamburg European Open last week as the 32-year-old begins to recover from a dreadful first half of 2021.

Prior to his run in Hamburg, Paire had only won two ATP Tour matches this year.

Mikael Ymer had to come from behind before he progressed with a 4-6 6-3 6-3 win over lucky loser Enzo Couacaud.

The top four seeds at the ATP 250 event – led by Wimbledon semi-finalist Denis Shapovalov – get a bye through the first round and are therefore yet to begin their campaigns.

At the Croatia Open Umag, meanwhile, Radu Albot came out on top as he claimed a three-set victory over Holger Rune, with top seed Albert Ramos-Vinolas and defending champion Dusan Lajovic not in action on day one.

Kevin Anderson landed his first title since January 2019 as the former Wimbledon finalist triumphed at the Hall of Fame Open on Sunday.

The one-time world number five served 16 aces in a 7-6 (10-8) 6-4 win over 20-year-old American Jenson Brooksby at the tournament in Newport, Rhode Island.

Playing the third grass-court final of his professional career, after being runner-up at Queen's Club in 2015 and at Wimbledon in 2018, Anderson outfought Brooksby to land a seventh ATP title.

Now ranked at a relatively lowly 113th, the 35-year-old South African former world number five saw off top seed Alexander Bublik in the semi-finals before getting the better of Californian prospect Brooksby in the title match.

"It's been a pretty tough run with some injuries," Anderson said, quoted on the ATP website. "But to be back here at the International Tennis Hall of Fame with such history, this couldn't be a better week for me to start, hopefully, my comeback.

"I'm very motivated to get back. But it all starts with each match, and I was able to really grind it out."

Anderson's last title had come on hard courts at the Maharashtra Open in Pune, India, where he got the better of Ivo Karlovic in a match where all three sets went to tie-breaks, and where Karlovic fired 36 aces in a losing cause.

Casper Ruud won his third ATP Tour title on Sunday thanks to a straightforward win over Federico Coria in the Nordea Open final.

The Norwegian needed just under 90 minutes to see off Coria, who was competing in his maiden tour-level final, getting the job done to win 6-3 6-3.

Ruud's electric start set the tone for the contest, as he raced into a 4-0 lead thanks to successive breaks – although Coria broke back to make it 4-1, his opponent's wobble was only brief.

Coria ensured the match was a little tighter initially in the second set, but Ruud's class showed as he rattled off three breaks on the trot and eventually converted his fifth match point in front of a joyous support.

"It was an incredible week, maybe the best week of my life," Ruud said after sealing the title without losing a single set.

"It's an incredible feeling playing here in Bastad with the Swedish, Norwegian and Danish support. There is nothing like that home crowd feeling.

"To win here means a lot. You get a little extra nervous as the No. 1 seed. Me and my father [former player Christian Ruud] have been joking about when I am going to beat him at this and this, and now I think I have beaten him in everything!

"The Ruud family can finally bring the trophy home to Norway. It is a special feeling having him here with me."

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.
