Stan Wawrinka reflected on a "really tough year" after racking up a new ATP 1000 milestone with his first-round victory over Giovanni Mpetshi Perricard at the Shanghai Masters.

The three-time grand slam champion secured a 7-6 (7-2) 7-6 (8-6) victory in China in what was the first ATP meeting between the two.

According to Opta Ace, it represented Wawrinka's landmark 100th hard-court victory in ATP 1000 events, becoming the 12th player to do so.

Speaking on court after the victory, the veteran 39-year-old said: "It's been a really tough year so far, but I'm not getting younger so I'm trying to keep pushing myself.

"I'm happy with the match. I think it was a really good level. I was playing really good, one of the best matches of the year for me.

"He's such an aggressive player. It was great to be here, so much support here, so I'm enjoying my time in China."

Wawrinka, who only had five ATP wins this year before featuring in Shanghai, next faces  Flavio Cobolli in round two.

Jannik Sinner began his Cincinnati Open campaign with a hard-fought 6-4 7-5 win over Alex Michelsen, bouncing back from his injury scare at the Canadian Open last week.

Sinner fell to a quarter-final defeat to Andrey Rublev in Montreal last time out, appearing to struggle with a hip issue throughout that loss after missing the Paris Olympics due to a bout of tonsillitis. 

However, the Italian played down any concerns over his fitness ahead of his last-32 match in Cincinnati, where he was pushed all the way by Michelsen but held firm to advance.

Sinner had to save eight break points in one hour and 52 minutes on court, committing as many unforced errors (19) as his American opponent.

However, breaks in the very first game of the opener and the penultimate game of the second set proved decisive for the Australian Open winner, who will now face either Sebastian Baez or Jordan Thompson for a quarter-final place.

Meanwhile, Stefanos Tsitsipas bounced back from his first-round Canadian Open exit at the hands of Kei Nishikori, fighting from a set and a break down to beat Jan-Lennard Struff 4-6 6-4 6-3.

Speaking after his win, Tsitsipas – who will face Jack Draper or Jaume Munar next – said: "I was down a break, and I managed to keep on fighting and get the break back. 

"Suddenly I felt like I was starting to figure out what really worked behind his serve. He made a few double faults, and I took that chance, got myself in the lead, and I think once I started reminding myself of my best qualities as a player, these things really started working."

Data Debrief: Sinner looking to stay perfect

Sinner's victory improved his record on hard courts to 25-2 for the season, and a first quarter-final berth at Cincinnati is now within his sights.

He has reached at least the last eight at all five ATP 1000 Masters tournaments he has played this year, though his only such title came in Miami in March.

Alexei Popyrin declared his victory at the Canadian Open “means the world” after he defeated Andrey Rublev in straight sets to claim his maiden ATP 1000 title.

Popyrin won 6-2 6-4 to become the first player to win the Canadian Open title in their first main draw appearance in 17 years. The last player to do so was 24-time Grand Slam singles winner Novak Djokovic in 2003.

The 25-year-old defied the odds to beat favourite and world number six Rublev in his third defeat of a top-10 opponent in Montreal.

For the current world number 62, it was a sign that all the effort had been worth it.

"It means the world, for all the hard work I've put in over the years, all the sacrifices I have made," said Popyrin.

"Not just me, but my family, my girlfriend, my team, everybody around me. They have sacrificed their whole lives for me and for me to win this for them is just amazing."

The victory also makes Popyrin the first Australian to win a Masters 1000 since Lleyton Hewitt won Indian Wells in 2003.

He became the fourth-lowest ranked ATP Masters 1000 champion, just two weeks after being defeated by Alexander Zverev on clay courts in the round of 16 in the Olympics men’s singles.

Popyrin fared better against Rublev, who remained optimistic about his performance despite the upset.

“It's a very positive and really good week. [It’s a] really big step forward, and I feel proud of myself that I was able to be really good all the week mentally,” reflected Rublev.

“If we compare my match against him at Monte-Carlo when I was losing, I was behaving 10 times more, and it was first round.

“Here it was a final. Much more pressure. Yes, I still showed a bit emotions today, but compare the matches when I was losing the same way, I think I did much better job.

“That's why I had a little chance in the second set, but it was just not my time I guess.”

Step aside Novak Djokovic, Rafael Nadal and Carlos Alcaraz, tennis has a new world number one on the block in Jannik Sinner.

The 22-year-old, born in San Candido, ended a 51-year wait for Italy to boast the ATP's best player in the world rankings after moving to top spot this month.

Sinner overtook Djokovic at the summit of the men's game after his French Open performance, reaching the Roland-Garros final before falling in a five-set thriller to the battling Alcaraz.

Having already secured his first major at the Australian Open earlier this year, Sinner's remarkable rise continued in Paris – but how has the Italian managed to do so?

Here, we unpack the best of the Opta data to delve into Sinner's surge to world number one.

Major champion in Australia

Sinner was crowned a grand slam champion for the first time in his career back in January, defeating Daniil Medvedev in the final after overcoming a two-set deficit in Melbourne.

Sweeping aside Djokovic in the last four and Andrey Rublev in the quarter-finals, his route to glory was far from straightforward, too.

Aged 22 years and 165 days at the time of his Melbourne Park triumph, Sinner became the youngest-ever player to achieve successive ATP top-five wins in the quarter-finals, semi-finals and final of a major, surpassing Michael Stich – 22 years and 262 days at Wimbledon in 1991.

That Medvedev victory, at the time, also marked Sinner's fourth top-five scalp of 2024.

Since 1973, Sinner is the only fourth player aged under 23 to claim four such wins in the opening three months of a season, after Bjorn Borg (1978-79), Miloslav Mecir (1987) and Andy Murray (2007 and 2009).

Special 2023 sets tone for this year's success

Sinner enjoyed a remarkable campaign last year, winning his first Masters 1000 title at the Canadian Open and finishing the season by reaching the showpiece of the ATP Finals.

He finished with a win-loss record of 64-15 in 2023, breaking the Open Era record previously held by Corrado Barazzutti (55, 1978) for most ATP match wins by an Italian in a calendar year.

En route to the Indian Wells semi-final defeat to Alcaraz, Sinner also claimed a 19th consecutive ATP match win after overcoming Jiri Lehecka, breaking Adriano Panatta's record for the longest winning streak at ATP level of any Italian in the Open Era.

It is hard to argue with his position at the top, too.

Sinner became only the fifth player before turning 23 to defeat the men's world number three times in a calendar year, having overcome Alcaraz and Djokovic (twice) in a remarkable 2023 season.

The Italian also helped his country lift the Davis Cup, though major individual honours were always around the corner for the excellent right-hander.

The best in the world

Australian Open successes and a fine 2023 campaign brought Sinner to his crowning moment in June as he became the first Italian to reach world number one since the ATP rankings started in 1973.

Sinner is one of four players in the past two decades to hold the ATP's number-one ranking before the age of 23, along with Roger Federer, Nadal and Alcaraz.

Since 2000, Sinner is also just the third male player taller than 188 centimetres to reach the summit of tennis before turning 23, along with Andy Roddick and Marat Safin.

Alexander Zverev claimed his second Italian Open title following a 6-4 7-5 victory over Nicolas Jarry in the final.

The German, who also triumphed in Rome seven years ago, captured his first silverware of the season - and sixth of his career in an ATP Masters event.

Having dropped just a single set on the way to his 11th Masters final, Zverev continued his impressive form by winning 95 per cent of his first-serve points (37 out of 39) and committing just eight unforced errors.

Jarry had enjoyed an impressive fortnight in Rome, defeating Stefanos Tsitsipas and Tommy Paul on the way to becoming the first Masters finalist from Chile since Fernando Gonzalez (also at the Italian Open) in 2007.

However, just two break points were enough to deny the 21st seed a fourth career ATP title, with Zverev eventually converting his fourth championship point to ensure a return to the winner's circle.

Data debrief

Zverev joins Rafael Nadal (10) and Novak Djokovic (six) as one of only three players since 2000 to win the Italian Open on multiple occasions.

Landing his second crown in Rome seven years after his first, it marks the longest gap in seasons between two men's singles titles at the event in the Open Era.

Meanwhile, Zverev became the most successful German male in ATP Masters events since the format's introduction in 1990, with his sixth such success seeing him eclipse Boris Becker's total of five.

Nicolas Jarry defeated Tommy Paul in three sets on Friday to set up a showdown with Alexander Zverev in the Italian Open final.

The men's world number 24 prevailed 6-3 6-7 (3-7) 6-3 in a little under three hours in Rome to reach his first ATP Masters 1000 final.

Jarry earned the only break of serve in the eighth game of the opening set, but Paul - who dropped just one set in four matches en route to this stage - hit back in the second.

Birthday boy Paul lost serve to trail 4-2 at one stage, but he produced one of the shots of the tournament at the ideal moment and soon dragged it back to 4-4.

A gruelling set concluded with Paul taking the tie-break 7-3, but Jarry was unperturbed and won the deciding set with his fifth match point to see off Paul in a gruelling contest.

Data Debrief: 

Jarry is the third male Chilean in the Open Era to reach the singles final of the Italian Open after Marcelo Rios (1997-98) and Fernando Gonzalez (2007).

The 28-year-old registered 13 aces against Paul to his opponent's seven and hit 35 winners to 19 in a deserved victory.

Alexander Zverev fought back from the brink to reach the Italian Open final on Friday, overcoming Alejandro Tabilo by a 1-6 7-6 (7-4) 6-2 scoreline in the last four.

Zverev was punished for a slow start as Tabilo took the opener within 32 minutes, but the German fought back in a one-hour, 15-minute slog of a second set.

The 2017 Italian Open champion put his foot down from 3-3 in the second-set tie-break, with Tabilo potentially feeling the effects of a fine run that included a last-32 upset of Novak Djokovic.

Zverev upped the intensity in the final set and won a huge 94 per cent of points behind his first serve as his opponent wilted, the third seed reaching the Rome final for a third time. 

Data Debrief: Zverev draws level with Becker

Zverev will now face either Nicolas Jarry or Tommy Paul in Sunday's final, which will be his 11th at ATP 1000 Masters level.

That tally pulls him level with Boris Becker for most such finals by a German player since the format's 1990 introduction.

Alexander Zverev moved a step closer to his second Italian Open title with a hard-fought 6-4 6-3 quarter-final win over Taylor Fritz, overcoming an injury scare en route to the last four.

Zverev – who triumphed on the clay in Rome back in 2017 – produced a dominant serving performance against another heavy hitter in Fritz, but only after an awkward fall early on.

The German sought medical attention after falling on his stomach in the third service game of the match, the slip leaving him bleeding from both hands. 

However, he soon shook off that knock and did not allow Fritz a single break point in a deeply impressive display, setting up a semi-final meeting with Chile's Alejandro Tabilo – the conqueror of Novak Djokovic – for Friday.

Data Debrief: Zverev gathering momentum

Zverev, the lone former champion remaining in the men's draw, is surely the favourite to win a tournament characterised by unfortunate withdrawals and shock defeats for the biggest names.

Seven of Zverev's 21 tour-level titles have come on clay, and he is yet to drop a single set in Rome this year. His three-year wait for an ATP 1000 title could soon be over.

Rafael Nadal will do everything he can to play at the French Open this month, but he admits he has a decision to make on his involvement after crashing out of the Italian Open on Saturday.  

Nadal – a 10-time champion in Rome – suffered a resounding 6-1 6-3 defeat against Hubert Hurkacz on the clay, the Pole producing a polished performance to halt his run in the second round.  

The Spaniard has said he will likely call time on his glittering career at the end of the season, having been troubled by hip and abdominal injuries in recent years.

The 37-year-old was also beaten by Jiri Lehecka in the last 16 at the Madrid Open last month, and he acknowledges he is currently some way short of the level required to challenge for a record-extending 15th French Open title.

Speaking after Saturday's defeat, Nadal said: "The time has come to make a decision, in case I might not play Roland-Garros. 

"One is to say, 'okay, I am not ready, I am not playing well enough'.

"Another is to accept how I am today and work the proper way to try to be in a different way in two weeks. If I have to say which side I lean towards, it's to try to play it and give my best.

"Physically I have some issues, but probably not enough to say no to playing in the most important event of my tennis career."

The year's second grand slam begins at Roland Garros on May 20, with the men's singles final taking place on June 9. 

Daniil Medvedev and Noami Osaka both advanced at the Italian Open with straight-sets wins on Saturday, the former eliminating Britain's Jack Draper with a 7-5 6-4 success.

Second seed Medvedev – who won the Rome event last year – was tested by Draper, the world number four saving seven of 10 break points faced in a one-hour, 47-minute contest.

Draper was in the ascendency when he broke Medvedev's serve to make it 5-5 in the first set, but Medvedev hit straight back before serving out the opener.

The Russian stepped things up from there and raced into a 5-1 lead in the second set, one Draper was unable to overturn as Medvedev teed up a last-32 clash with Hamad Medjedovic for Sunday.

In the women's draw, four-time grand slam champion Osaka overcame 10th seed Daria Kasatkina in another impressive straight-sets triumph, two days after recording her first clay-court win over a top-20 opponent in Marta Kostyuk.

She eased to a 6-3 6-3 victory in Saturday's last-32 encounter and will now face China's Qinwen Zheng for a place in the quarter-finals on Monday.

Data Debrief: Osaka's new love for clay

Coming into this year's Italian Open, Osaka was 0-8 throughout her career against top-20 opponents on clay, but she has now recorded two such wins in a row for the very first time.

Rafael Nadal is out of the Italian Open after he was defeated in straight sets by Hubert Hurkacz in Rome on Saturday.

Nadal is a 10-time Italian Open champion, but his chances of an 11th and likely final title in Rome were ended in ruthless fashion by Hurkacz, who dominated on his way to a comfortable 6-1 6-3 triumph.

While Nadal held in his first service game of the second-round match, Hurkacz quickly took over and broke his 37-year-old opponent twice as he controlled the opening set.

Nadal showed some resolve in the second set, but a break of his serve in the third game left him with an uphill battle.

World number nine Hurkacz was in charge, and it was a position of control he would not relinquish as he broke Nadal once more to clinch victory.

Hurkacz will now take on Tomas Martin Etcheverry as he bids to reach the fourth round for the maiden time in Rome. For Nadal, who has indicated he will retire after the 2024 season, this will not have been how he wished to bow out in Rome as he prepares for the start of the French Open later this month.

Data debrief

Hurkacz became just the third player to concede fewer than five games en route to victory over Nadal on clay at ATP level, along with Olivier Rochus (Mallorca round of 16 2002) and Gaston Gaudio (Hamburg round of 16 2003).

Hurkacz dominated his contest with Nadal, winning all eight of his service games and breaking the 22-time grand slam champion on four occasions as he eased into the fourth round.

Carlos Alcaraz has withdrawn from next week's Italian Open due to the arm injury that troubled him at the Madrid Open, where Andrey Rublev and Felix Auger Aliassime will face off in Sunday's final.

Alcaraz saw his bid for a third successive Madrid Open crown halted by Rublev in the quarter-finals on Wednesday, the Spaniard being pegged back after taking the opening set in a 4-6 6-3 6-2 loss.

The two-time grand slam champion – who had won his previous 24 matches at Spanish clay-court events – looked tired throughout that match and has now withdrawn from next week's ATP 1000 Masters event in Rome.

In a post to X, Alcaraz wrote: "I felt pain after playing in Madrid, discomfort in my arm. 

"Today I had some tests and I have muscle edema in the pronator teres, a consequence of my last injury. Unfortunately I won't be able to play in Rome. I need rest to recover and be able to play 100 per cent pain-free." 

Alcaraz only has limited time to recover if he is to feature at the year's second major, with the French Open due to begin on May 20.

Alcaraz's conqueror Rublev advanced to the final of the Madrid event on Friday, producing a commanding performance to beat American Taylor Fritz 6-4 6-3 in the last four.

Rublev entered the Madrid Open on a run of four straight losses, but he is now into his third ATP Masters 1000 final since the start of 2023 – a tally only bettered by Alcaraz and Daniil Medvedev (four apiece).

His opponent in Sunday's showpiece match will be Auger Aliassime, who progressed by virtue of a walkover on Friday after semi-final opponent Jiri Lehecka was forced to retire through injury.

Lehecka left the court for treatment on a back injury after just six games, with Auger Aliassime having held serve for 3-3. He only managed to play three further points on his return before calling the match to a halt in a disappointing ending to the night session.

Data Debrief: Lucky Auger Aliassime

Auger Aliassime would surely have preferred to win his semi-final the traditional way, but the Canadian should be fresh for Sunday's final after spending very limited time on court.

He has progressed through three rounds at this year's Madrid Open courtesy of a retirement or walkover, with Jakub Mensik and Jannik Sinner also stricken.

He is the first player since 1990 to progress through three rounds via retirement or walkover at a single ATP Masters event.

Jannik Sinner has withdrawn from the Madrid Open due to a hip injury ahead of his scheduled quarter-final clash with Felix Auger Aliassime.

The world number two was due to face Auger Aliassime for a place in the semi-finals after fighting back to overcome Karen Khachanov in three sets on Tuesday.

However, the Italian has been advised to withdraw to avoid aggravating an issue with his right hip, which he says has troubled him throughout the tournament. 

Sinner, who is 28-2 for the season and won his first grand slam title at the Australian Open earlier this year, wrote on X: "Very sad to have to withdraw from my next match here in Madrid. 

"My hip has been bothering me this week and has slowly been getting more painful. Taking the advice from the doctors, we decided it's best to not play further and make it worse."

Sinner's withdrawal means Auger Aliassime will advance to his first ATP Masters 1000 semi-final since 2022, with Daniil Medvedev or Jiri Lehecka – who eliminated Rafael Nadal on Tuesday – up next for the Canadian. 

On the other side of the draw, two-time defending champion Carlos Alcaraz suffered a surprise exit at the hands of Andrey Rublev on Wednesday, with the Russian set to face either Taylor Fritz or Francisco Cerundolo in the last four.

Carlos Alcaraz saw his hopes of a third straight Madrid Open crown dashed on Wednesday, as Andrey Rublev fought back to seal a statement quarter-final win over the defending champion.

Alcaraz had been pushed close in the last 16 by Jan-Lennard Struff on Tuesday, requiring two tie-breaks to see off the German in three sets, and those exertions seemed to take their toll as he produced a below-par display on Wednesday.

Seven unforced errors from Rublev helped the home favourite take the opener, but he appeared to tire from there as his seventh-seeded opponent fired in 27 winners in a 4-6 6-3 6-2 victory.

Rublev broke Alcaraz's serve in the first and fifth games of the decider, also serving impressively to deny the Spaniard a single break point after a nervous first hold. 

Alcaraz's exit ended home interest in the tournament, just one day after five-time champion Rafael Nadal was dumped out in the last 16 by Jiri Lehecka.

Speaking to Sky Sports Tennis, Rublev said: "I can't believe that I was able to stay calm throughout the match. I didn't say a word and even I'm impressed by that!

"I want to believe that I have been working on this because if not, then I'm stupid. I just thought to myself to keep trying, keep fighting, keep believing in yourself."

Data Debrief: Major scalp for Rublev

To say Rublev entered Wednesday's match as the underdog would be an understatement. Alcaraz was looking to become the first player to win three straight Madrid Open singles titles, and was 24-0 in Spanish clay-court events since the start of 2022.

Rublev, though, was not overawed by the occasion and punished a sluggish performance from the world number three. Wednesday's win was his first over a top-three opponent since 2022, and he will now face either Taylor Fritz or Francisco Cerundolo in the last four.

Daniil Medvedev overcame a stern test against Sebastian Korda at the Madrid Open on Monday, fighting back from the brink of defeat to seal a 5-7 7-6 (7-4) 6-3 win and reach the last 16.

The world number four was staring at an early elimination when Korda took the opening set and put himself within two points of victory on two occasions, at both 5-4 and 6-5 up in the second.

However, Medvedev twice held firm on his own serve to force a tie-break, and the pair exchanged mini breaks before the 2021 US Open champion seized control to take it 7-4.

Medvedev's performance was error-strewn in parts, but he found more consistency in the third set, claiming the all-important break eight games in after repeatedly testing Korda's forehand. 

Medvedev will now face Alexander Bublik for a place in the quarter-finals on Tuesday after the 17th seed overcame Ben Shelton in three sets.

Data Debrief: Medvedev overcomes awkward opponent 

Medvedev has not always had things all his own way against Korda, who eliminated him from the Australian Open and the Shanghai Masters in 2023.

Prior to Monday's match, he was 23-2 versus American players since the start of 2021, with both losses coming against Korda. However, having also beaten Korda en route to the Indian Wells Open final last month, he seems to have put that hoodoo behind him.
