Carlos Alcaraz has his sights set on climbing to the summit of the ATP rankings after becoming the youngest player to crack the top five since Rafael Nadal.

The Spaniard was downed in the Hamburg European Open final by Lorenzo Musetti over the weekend but nevertheless saw a rise in his stature to a career-high position of fifth.

In doing so, it makes the 19-year-old the second-youngest male to break into the top five this century, trailing only Nadal and bettering Novak Djokovic by a matter of months. 

"It means a lot," Alcaraz stated. "The hard work that I put in every day for reaching my dreams, [number] 1, and little by little I'm reaching my dream.

"Top five for me is pretty amazing and I will keep going to be [number] 1."

Had Alcaraz won in Hamburg, he would have risen to fourth, while other movements in the rankings include a rise to number 31 for Musetti and a return to the top 200 for Dominic Thiem, at number 199.

Lorenzo Musetti won the first ATP Tour title of his career as he defeated fellow up-and-comer Carlos Alcaraz in Sunday's Hamburg European Open final.

Top seed Alcaraz ensured he would become the youngest player in the top five of the ATP rankings since Rafael Nadal in 2005 with his semi-final victory over Alex Molcan.

But the 19-year-old paid the price for an error-strewn display on Sunday, as Musetti, 20, took the crown 6-4 6-7 (6-8) 6-4.

Alcaraz was guilty of a slow start on the clay, with four wild unforced errors helping Musetti go a break up after the very first game. Although the Spaniard instantly hit back, his opponent gobbled up his next break point to take a 4-3 lead en route to winning the set.

Musetti then took charge early on in the second to go 2-0 ahead, but Alcaraz showed admirable resolve to see off a couple of match points and level the set at 5-5, before remarkably tying the contest in a tie-break that saw three more championship points squandered.

The deciding set was evenly contested almost throughout, until Musetti broke serve to make it 6-4 and take the match on his sixth championship point as Alcaraz hit a backhand long.

On a momentous day for the Italian, his jubilation was plain to see as he spoke afterwards.

"I have no words because it was a rollercoaster until the end," Musetti said on court. "I had so many match points. Carlos was so good on the match points, [I had] so many chances.

"But I think the key of the match was to keep calm and [have] all the patience [with] myself because it was really not easy.

"Carlos was putting so much effort in the match points when he was down, so it was not easy to find the energy to come back.

"But I cannot describe what I am feeling right now. I think I am still dreaming."

On the subject of the five match points he surrendered, Musetti added: "Of course I was really upset, but I tried to not show my opponent my reaction.

"I tried to forgive [myself for] all the match points and all the points [when] I couldn't do it. I think that was the most [important] thing, even for me, because I didn't expect the win after all this rollercoaster, so I'm super happy to be here and to be the champion."

Musetti and Alcaraz could end up meeting again in the coming week in Umag, where the latter is the defending champion and top seed.

Casper Ruud mounted an impressive comeback to defend his Swiss Open crown, after seeing off Matteo Berrettini in a three-set thriller in Gstaad.

The Norwegian, the beaten finalist at this year's French Open, made it successive triumphs at Roy Emerson Arena, after overcoming a first-set deficit to win 4-6 7-6 (7-4) 6-2.

It takes clay specialist Ruud to an eighth overall title on the surface and a third of the year, following victories at the Argentina Open in February and Geneva Open in May.

For Berrettini – also chasing a third title of the year after victory at the Stuttgart Open and Queen's – he will be left to rue letting his first-set advantage slip, after getting the drop on his rival.

The Italian was competing in his first event since he was forced to withdraw from Wimbledon with COVID-19, and made an impressive start under glorious sunshine on Sunday.

Yet Ruud was able to take him to the wire in the second set, before breaking his serve twice in the decider to emerge triumphant in Gstaad for the second year in a row in the end.

Former tennis star Mardy Fish said he was "proud" to be the first person to play on both the ATP Tour and the PGA Tour after swapping his racquet for a bag of clubs.

The 40-year-old won six ATP titles and once ranked as high as seventh in the world in 2011, before retiring from tennis four years later.

However, he has recently been playing amateur golf and was given a special exemption to play in the PGA Tour's 3M Open in Minnesota, his hometown.

Fish was unable to make the cut, finishing 13 over par after his two rounds, with only three players carding higher scores.

He was grateful for the opportunity, though, and took to Twitter on Saturday to reflect on his achievement, posting: "What an incredible experience playing in the 3M Open. Truly a week I will never forget.

"I'm proud to be the first person to play on the ATP Tour and the PGA Tour. Chase your dreams, no matter how ridiculous they may be! Thank you for the incredible support all week Minnesota!"

Although he did not quite perform to the level hoped, Fish did card a respectable 74 in Friday's second round, hitting eight of 14 fairways and seven of 18 greens in regulation.

Golf great Jack Nicklaus has previously labelled Fish the best non-professional golfer he has ever played with.

"We played nine holes, and he drove the ball on every single hole in the middle of the fairway; further than I have seen anybody hit it who is not a professional," Nicklaus said.

"He shot 31 for nine holes. I said, 'Mardy, what are you doing? You have got a talent, and you are young enough to take advantage of it. You need to go play golf.'"

Carlos Alcaraz will play Lorenzo Musetti in the Hamburg European Open final following a straight-sets victory over Alex Molcan on Saturday.

The Spanish teenager is targeting a fifth ATP title of the year, which would move him ahead of Rafael Nadal, having already triumphed in Rio, Miami, Barcelona and Madrid.

Alcaraz is set to move into the top five of the ATP rankings for the first time after seeing off Slovakia's Molcan 7-6 (7-2) 6-1 to reach yet another championship match on his debut in Hamburg.

The top seed broke twice in the opening set but was pegged back on both occasions by Molcan, who was striving to reach a third final of 2022 after finishing as runner-up in Marrakech and Lyon.

But the 19-year-old dominated the tie-break, and found another gear to storm into the final as he made it eight successive sets won this week.

"It was tough," Alcaraz said. "Obviously, [Alex] played really well. The first set was really close; I'm really happy to be able to end the first set playing well.

"I couldn't read the drop shots from him. He was better on the drop shots today, so I was a little bit [frustrated] in the first set.

"In the second set, I think he was down a little bit; he didn't play well. I finished the match with a lot of confidence and played very well."

Standing between Alcaraz and another title is Musetti, who will appear in his maiden ATP final after he overcame Francisco Cerundolo 6-3 7-6 (7-3).

The Italian, who is set to climb into the world's top 50 for the first time, had lost six consecutive ATP Tour matches prior to this week.

But the 20-year-old continued his resurgence; ending the Bastad champion's eight-match winning streak by roaring back from 3-1 down in a second-set tie-break.

Meanwhile, Matteo Berrettini and Casper Ruud will target a third title of 2022 when they lock horns in the Swiss Open showpiece.

Berrettini - a winner in Stuttgart and Queen's before a positive COVID-19 test ruled him out of Wimbledon - registered his 12th successive victory, putting former US Open champion Dominic Thiem to the sword 6-1 6-4 in 78 minutes.

Reigning champion Ruud raced past Albert Ramos-Vinolas; winning five out of seven break points in a resounding 6-2 6-0 triumph.

Carlos Alcaraz outclassed Karen Khachanov to reach the semi-finals of the Hamburg European Open, while Matteo Berrettini will face Dominic Thiem in the last four at the Swiss Open.

Top seed Alcaraz only needed an hour and nine minutes to beat Russian Khachanov 6-0 6-2 in a clay-court masterclass on Friday.

The 19-year-old Spaniard moved a step closer to winning a fifth title this year with a dominant performance, breaking the Russian five times in a one-sided contest.

Alcaraz hit 21 winners as Khachanov was given a harsh lesson and the teenager will next face Alex Molcan, who was 2-0 up in the second set after winning the first on a tie-break when Borna Coric retired due to injury.

"I played unbelievable today, probably one of my best matches this year," Alcaraz said of his win against Khachanov. "I'm pretty happy with the performance that I'm playing in this tournament. Yesterday [a victory over Filip Krajinovic] was amazing as well.

"I'm training every day to be solid and at the same time to be aggressive. That is my game."

Francisco Cerundolo and Lorenzo Musetti will contest the other semi-final in Hamburg after beating Aslan Karatsev and Alejandro Davidovich Fokina respectively.

A rejuvenated Thiem is enjoying another hugely encouraging week and will take on Berrettini in his first semi-final of the year following a 6-4 6-3 defeat of Peruvian qualifier Juan Pablo Varillas in Gstaad.

Austrian Thiem has not played in a final since winning his only grand slam at the 2020 US Open, but he claimed his first ATP-level victory for 14 months in Bastad last week and is through to his first semi-final since May 2021 after bossing the baseline battle with Varillas.

It was not all plain sailing for Berrettini, who roared back to beat Pedro Martinez 3-6 7-6 (7-5) 6-1 after the Spaniard was in command of a second-set tie-break at 5-1, but the second seed extended his winning run to 11 matches.

Top seed Casper Ruud got the better of Jaume Munar 7-6 (7-3) 7-6 (7-4), booking a showdown with Albert Ramos-Vinolas, who came through a three-set battle with Nicolas Jarry.

Andrey Rublev crashed out of the Hamburg European Open in straight sets against Francisco Cerundolo, as top seed Carlos Alcaraz cruised past Filip Krajinovic to reach the quarter-finals.

Second seed Rublev was the latest scalp of Cerundolo's fine run of form, the Argentine making it seven consecutive wins by wrapping up a 6-4 6-2 success in just an hour and a half in Germany.

Having furthered his momentum with a second top-10 win in as many weeks, Cerundolo said: "It is the first time it has happened for me. I am playing against the top guys and I am playing well, it is unbelievable."

Cerundolo will face Aslan Karatsev in the last eight after he recovered from a set down to beat Daniel Elahi Galan 3-6 6-3 6-4.

World number six Alcaraz fared better than Rublev, registering a 7-6 (7-4) 6-3 win over Krajinovic to tee up a final-four meeting with Karen Khachanov, who beat Fabio Fognini in straight sets.

Meanwhile, a host of big names including Casper Rudd and Matteo Berrettini reached the last eight of the Swiss Open in Gstaad, as Dominic Thiem continued his revival with a win over Federico Delbonis.

Thiem reached his second quarter-final in as many weeks with an impressive 7-6 (8-6) 6-3 triumph despite letting a 5-2 lead slip in the opener, registering his first tour-level straight-sets victory since May 2021.

Having set up a meeting with Juan Pablo Varillas, the 2020 US Open champion beamed: "I have won two matches which means a lot to me right now, I really need those ranking points. Every match win is something very special."

The Austrian will be joined in the next round by first and second seeds Ruud and Berrettini, who eased past Jiri Lehecka and Richard Gasquet respectively.

Spanish duo Albert Ramos-Vinolas and Pedro Martinez also both progressed to the last eight despite dropping a set, with the latter setting up an enticing clash with Berrettini on Friday.

The men's tennis tour has scrapped plans to stage four tournaments in China later this year as the pandemic continues to take its toll on the sporting calendar.

Mandatory quarantine rules make it unfeasible for international players and tour officials to travel to the events, including the Shanghai Masters, a top-tier ATP 1000 tournament.

The lucrative Shanghai event had been due to run from October 9-16 and would have featured many of the world's top players.

Also cancelled are the Chengdu Open and the Zhuhai Championships, which were scheduled to begin on September 26, and the China Open, billed for the following week.

The ATP said it had cancelled the three-week China swing "due to ongoing restrictions related to COVID-19".

It marks a third successive year in which the run of tournaments has had to be cancelled, with China last hosting ATP events in 2019, before the pandemic hit.

At the same time as it cancelled the tournaments in China on Thursday, the ATP made provision for its players to keep earning by announcing six new events to take place in September and October.

Those events will be played in San Diego, Seoul, Tel Aviv, Florence, Gijon and Naples, the ATP said, with all at ATP 250 level, the lowest rung of the main tour.

The WTA, which runs the women's tour, announced last December it would be suspending all its tournaments in China due to concerns over the wellbeing of Peng Shuai, a professional tennis player who appeared to allege she had been sexually assaulted by a powerful former government official.

Former doubles world number one Peng has since denied making the accusations, yet the WTA has remained concerned for her safety and freedom.

Novak Djokovic must be allowed to play at the US Open because a ban over his COVID-19 vaccination refusal would be "crazy", according to John McEnroe.

The Serbian won his seventh Wimbledon title this month, but the All England Club event was just his second major of the year after missing the Australian Open in January.

Djokovic was not permitted to play in the opening major of 2022, where issues surrounding his visa ended with him being deported from Melbourne on public health grounds due to not taking the vaccine.

The 35-year-old hopes to compete at Flushing Meadows in August but has insisted he will not take the vaccination, while the United States is refusing to allow unvaccinated foreigners to enter the country.

The USTA confirmed it would adhere to US rulings surrounding coronavirus protocols, despite including Djokovic on the entry list for the final slam of the year on Wednesday.

Seven-time major champion McEnroe has previously suggested Djokovic should be allowed to compete and reiterated his calls for the 21-time slam winner to be exempt from vaccination regulations.

 "I mean, we have to find a way to get Novak into the US Open," McEnroe told Tennis365.

"How can he not be there? He has just won Wimbledon, he is a great champion and he should be in the US Open.

"I don't agree with his decision not to get vaccinated, but I respect it. He is one of the fittest guys in the world and everything he puts into his body, he is watching carefully.

"Now we are saying that because of his choice, he can't play at the US Open. I mean, come on. He has already been deported from Australia for the same reason and here we are again."

For Djokovic to be allowed into the United States, it would require a change of tack from law-makers, or he would have to be considered suitable for an exemption.

Among those who would be eligible for such an exemption are "persons whose entry would be in the national interest".

"I hope someone finds a way to sort this out," McEnroe said. "It's crazy that Novak misses the US Open at this stage."

Pablo Carreno Busta saw his title defence at the Hamburg European Open come to an early end as he crashed out on Wednesday, while Andrey Rublev progressed with ease.

Carreno Busta fell to a 6-3 1-6 7-6 (7-5) second-round defeat against Slovakian Alex Molcan, who progressed to a fourth ATP Tour quarter-final this season.

World number 48 Molcan will next meet Borna Coric after the Croatian eased past Tallon Griekspoor 6-3 6-4, registering back-to-back tour-levels wins for the first time in 17 months.

Second seed Rublev coasted through his first-round clash with Ricardas Berankis, triumphing 6-3 6-4 as he improved his record at the ATP 500 clay-court event in Germany to 10-2.

"I am happy with my performance. Ricardas is a really tough player," said world number eight Rublev, who is aiming for his fourth title of the season after success in Marseille, Dubai and Belgrade.

"He hits the ball really hard and plays fast, so I had to bring intensity from the first game. I am really happy with how I was serving today and I hit some great shots from the baseline.

"The game he broke me in the second set he played really well. He returned really aggressively and I don’t think I made one first serve. But then I kept [my] focus and broke him straight away again."

Alejandro Davidovich Fokina was another comfortable winner, easing past Jozef Kovalik 6-2 6-2 to set up a quarter-final contest with Lorenzo Musetti, who beat Emil Ruusuvuori 6-4 7-5.

Play was suspended early at the Swiss Open due to bad weather, with Spaniard Jaume Munar downing Alexander Ritschard 6-3 6-3 in the only match of the day to reach the last eight.

That meant top seed Casper Ruud will have to wait until Thursday to face Jiri Lehecka in Gstaad, with third favourite Roberto Bautista Agut also seeing his match with Juan Pablo Varillas pushed back a day.

Novak Djokovic looks set to miss the US Open after the USTA confirmed it would respect the United States government's policy regarding unvaccinated travellers from outside the country. 

Djokovic has already missed one grand slam this year, with the 21-time major champion absent from the Australian Open after a protracted saga surrounding his visa ended with him being deported on public health grounds. 

The Serbian was permitted to play at the French Open and Wimbledon, winning the latter for the seventh time in his career, despite being unvaccinated against COVID-19. 

However, he is unlikely to have a chance to compete for a fourth singles title at Flushing Meadows. 

Djokovic was included on the entry list for the final slam of 2022, but the U.S. government does not permit unvaccinated non-U.S citizens to enter the country. 

In a statement released alongside the entry lists, the USTA said: "Per the ITF Grand Slam rulebook, all eligible players are automatically entered into the men's and women's singles main-draw fields based on ranking 42 days prior to the first Monday of the event. 

"The US Open does not have a vaccination mandate in place for players, but it will respect the U.S. government's position regarding travel into the country for unvaccinated non-U.S. citizens." 

Should Djokovic miss the New York major, it will mean he will not get the chance to play in a grand slam until the 2023 French Open. 

Having had his visa to enter Australia cancelled, Djokovic is banned from re-applying for three years. Unless that ban is reversed or reduced, the 35-year-old may well have played his final Australian Open. 

Djokovic is one major title shy of Rafael Nadal's record of 22 following his four-set win over Nick Kyrgios in the Wimbledon final. 

He reached the final of last year's US Open but lost to Daniil Medvedev in straight sets, preventing him from claiming the calendar Grand Slam. 

A month later, the White House issued a presidential proclamation declaring that non-U.S. citizens must be vaccinated to enter the country, effectively ending his hopes of going one better in 2022. 

Carlos Alcaraz was made to come from a set down but finally overcame Nicola Kuhn in the first round of the Hamburg European Open.

The highly rated Spanish teenager eventually downed the German wildcard 3-6 6-1 7-6 (7-3).

Kuhn, ranked 259 in the world, was aggressive early on against Alcaraz, and was rewarded with the first set.

But the 19-year-old – playing as top seed in an ATP Tour event for the first time – rallied to ease through the second set, before being made to work much harder to clinch the win on a tie-break.

Alcaraz will now play Filip Krajinovic in the second round after the Serbian also won in a third-set tie-break against Sebastian Baez 6-1 4-6 7-6 (8-6).

Three seeded players crashed out on Tuesday in straight sets, with third favourite Diego Schwartzman losing against Emil Ruusuvuori 7-5 6-4, sixth seed Nikoloz Basilashvili beaten by Aslan Karatsev 6-4 6-0, and eighth seed Holger Rune going down 7-6 (10-8) 7-5 to Tallon Griekspoor. 

Fourth seed Pablo Carreno Busta eased through against Luca Nardi 6-2 6-1, while there were also wins for Fabio Fognini, who sealed his 400th career victory, as well as Daniel Elahi Galan, Borna Coric and Francisco Cerundolo.

At the Swiss Open in Gstaad, sixth seed Cristian Garin lost 6-3 6-4 to Yannick Hanfmann and seventh favourite Hugo Gaston fell to Dominic Thiem despite winning the first set, losing 1-6 6-1 7-6 (9-7).

Elsewhere, Frenchman Richard Gasquet beat Roberto Carballes Baena 7-5 6-4, while his compatriot Benoit Paire retired hurt when a set and a break down against Elias Ymer.

A tight game between Swiss pair Dominic Stricker and Marc-Andrea Huesler saw the former prevail 6-7 (2-7) 7-6 (7-2) 6-4, and an all-Spanish affair was similarly close as Jaume Munar defeated Bernabe Zapata Miralles 6-3 3-6 7-5.

There were also wins for qualifiers Juan Pablo Varillas and Nicolas Jarry against Lorenzo Sonego and Thiago Monteiro respectively.

Alejandro Davidovich Fokina sprung a surprise in the first round of the Hamburg European Open as he knocked out fifth seed Botic van de Zandschulp.

Van de Zandschulp reached the round of 16 at Wimbledon before losing Rafael Nadal, and he was undone by another Spaniard on the clay in Germany.

Davidovich Fokina broke Van de Zandschulp's serve six times en route to a 6-4 6-4 victory.

He will next face qualifier Jozef Kovalik, who also progressed on Monday alongside Slovakian compatriot Alex Molcan.

Lorenzo Musetti prevailed in three sets against Dusan Lajovic, while Karen Khachanov went the distance in beating Jan-Lennard Struff.

There was a shock at the Swiss Open Gstaad as home wild card Alexander Ritschard knocked out eighth seed Joao Sousa in straight sets.

Fifth seed Pedro Martinez beat fellow Spaniard Carlos Taberner, while there were also wins for Federico Delbonis and Jiri Lehecka.

Maxime Cressy staged an impressive fightback in the Hall of Fame Open final to outlast Alexander Bublik and scoop his first ATP Tour title.

When he trailed by a set and 3-0, Cressy's hopes looked almost forlorn, yet the French-American came back to win 2-6 6-3 7-6 (7-3) in two hours and 23 minutes.

The run of six consecutive games in the second set saved Cressy's skin, before he edged a decider against Russian-born Kazakh rival Bublik in which neither man could force a break of serve.

Cressy had a brief injury timeout near the end of the third set, before sweeping through the tie-break.

The grass-court tournament in Newport, Rhode Island, earlier saw Lleyton Hewitt inaugurated to the International Tennis Federation's Hall of Fame, with the former US Open and Wimbledon champion on hand to receive the accolade.

Hewitt won the last ATP title of his career at the Hall of Fame Open in 2014, having lost in the final in the previous two seasons.

The 41-year-old Australian described the Hall of Fame entry on Sunday as "an incredible honour", saying he had previously considered it out of his reach and "for the people that were my idols growing up and the absolute legends of the sport".

Francisco Cerundolo claimed his first ATP title with a straight-sets victory over fellow Argentinian Sebastian Baez at the Swedish Open.

Cerundolo had lost his only previous final, again against a fellow countryman in the form of Diego Schwartzman at last year's Argentina Open.

But he was not to be denied this time around on the clay in Bastad on Sunday.

The two players went into this tournament with just five places separating them in the ATP rankings, and they proved to evenly matched in the first set.

World number 34 Baez struck with a break in the opening game only for the 39-ranked Cerundolo to immediately hit back in kind.

Cerundolo saved six break points to hold for a 6-5 lead but then saw two set points go begging.

He dominated the subsequent tie-break, however, and maintained the momentum in the second, serving out a 7-6 (7-4) 6-2 win to love.
