Jannik Sinner continued his quest to end his stellar season with the ATP Finals title after downing Taylor Fritz in straight-sets to earn his second win of the tournament. 

Sinner emerged a 6-4 6-4 victor in an hour and 40 minutes in Turin, with his latest triumph improving his record to 7-0 on indoor hard courts in 2024. 

The Italian showed his intentions with a love service game to open the first set, but was matched by his American opponent, who was also looking to maintain his perfect start. 

Sinner missed four break points in the eighth game, but made no mistake in Fritz's following service game to claim the early advantage in Turin. 

Fritz again traded blows with the year-end world number one, but would again lose a decisive break late in the second set that put Sinner within touching distance. 

The American exchanged in another pulsating rally with his opponent, but sent a backhand wide to send Sinner through and to the top of the Ilie Nastase Group after two matches.

Up next for Sinner is Daniil Medvedev, who beat Alex de Minaur earlier on Tuesday, while Fritz will face the Australian on Thursday. 

Data Debrief: The Italian Job

In a back-and-forth tussle with Alexander Zverev to end the year with the most wins, Sinner levelled the German with his Tour-leading 67th victory in 2024 on Tuesday. 

He also sealed a 12th win against an American opponent this season, only managing more wins against Ben Shelton (three) this season than Fritz (two, level with Alex Michelsen). 

Sinner (2023-24) is only the third player in the Open Era to claim 47+ ATP match wins on hard court in consecutive seasons after Roger Federer (2005-06) and Novak Djokovic (2012-13, 15-16).

Daniil Medvedev credited his ability to "block out the noise" as crucial in getting his ATP Finals campaign up and running with a straight-sets victory over Alex de Minaur.

Medvedev, who lost his opening game of the tournament to Taylor Fritz, returned to winning ways with a 6-2 6-4 triumph over the Australian in 78 minutes on Tuesday. 

The Russian cut a frustrated figure in his defeat to Fritz on Sunday, breaking his racket and was docked a point after serving a third consecutive double fault during the encounter.

However, the fourth seed produced an expertly measured performance, winning 20 out of 31 baseline points in the opening set to claim the early advantage. 

The second set was more evenly contested, but Medvedev secured a crucial break point in the ninth game, going on to seal his first top 10 win on hard courts since March. 

"After the last match I was too tired to fight mentally the way I do and so, during the match, when it doesn't work your way, you want to win and when you start losing you get frustrated," Medvedev said. 

"So I went into this match thinking, if I lose I go home on Thursday for sure and if I win then I have the chance to have a good feeling. I tried to hit some shots and it worked well and I'm ok with it.

"A lot of football players do it [block the noise]. It's more about social media and for sure after my performance with Taylor and some of my comments ... I tried to read it less.

"I went into this match trying to block the noise even from myself, so no tantrums and I really didn't care what was happening on the court."

Medvedev will seek to bolster his hopes of progressing from the John Newcombe Group when he takes on Jannik Sinner next, with the Italian in action against Fritz later on Tuesday. 

Data Debrief: Cool, calm and collected

Medvedev kept his hopes of sealing a second ATP Finals crown alive with a composed display against De Minaur, improving his record to 45-19 for the season. 

While the Russian produced more unforced errors (18) than De Minaur (15), Medvedev showed his quality by hitting 24 winners, 14 of which came with his forehand. 

Medvedev also claimed his sixth top 10 win of 2024, while also improving his head-to-head record against his Australian opponent to 7-3, avenging his defeat in the French Open round of 16 earlier this year. 

Alexander Zverev insisted improvements needed to be made despite kickstarting his ATP Finals campaign with a straight-set triumph over Andrey Rublev on Monday. 

Zverev, who is going in search of a third crown at the year-end tournament, emerged a 6-4 6-4 victor in 72 minutes in Turin to claim a Tour-leading 67th win of 2024. 

Rublev, however, got off to a blistering start to the encounter, winning each of his 13 points on serve, only for a lapse in the seventh game that allowed Zverev to take the opening set.

Zverev continued to trade blows with his opponent, but he claimed the decisive break point in the ninth game to maintain his dominant record in opening round-robin matches at the event (6-1). 

"I'm looking forward to the next few matches, and hopefully I can improve on a few more things because I don't think this match was perfect to be honest," Zverev said.

"I still think there's a few more things that can be better. I missed a few balls from the baseline and I feel I wasn't as sharp movement-wise as I would like to be."

Zverev joined Casper Ruud at the top of the John Newcombe Group after he had beaten Carlos Alcaraz earlier on Monday, with the Norwegian up next for the world number two.

Data Debrief: Alexander the Great

After winning the ATP Finals in 2018 and 2021, Zverev's performance against the big-hitting Rublev was a sign of his intentions to complete a hat-trick of victories at the year-end tournament. 

The German struck 22 winners compared to his opponents' 10, along with converting both break points he was presented with. 

Excluding the Laver Cup, Zverev also claimed the 50th ATP top 10 win of his career, becoming the first player born since 1990 to achieve the feat.

Carlos Alcaraz revealed that he struggled with illness during his opening game loss at the ATP Finals to Casper Ruud on Monday. 

Alcaraz looked out of sorts as he fell to a 1-6 5-7 defeat to Ruud in just 86 minutes in Turin, and now faces an uphill struggle if he is to progress from the John Newcombe Group.

During the contest, the Spaniard hit 26 unforced errors compared to his opponents' 10, while also failing to save any of the four break points he faced. 

It also marked Alcaraz's first loss against Ruud in their fifth match against each other, with the 21-year-old confirming he had felt unwell leading up to the tournament. 

“I don’t like talking about things like this because it sounds like an excuse and I don’t want to take anything away from what Casper did to win the match,” began Alcaraz.

“Before coming here, I was unwell at home. When I got to Turin, practice was going well; I could handle long rallies, competing and playing.

"And I hoped things would get better as the days went by.

"I don’t know if it was because of the nerves of the first match, but I didn’t feel completely well. My stomach limited my game a lot and made me feel uncomfortable.

"I could’ve done better. I’m not going to feel good in every match I play throughout the year, but it really limited me in terms of my recovery.”

Alcaraz will be back on court on Wednesday, when he takes on the loser of Monday's clash between Alexander Zverev and Andrey Rublev.

Failing to win would see the four-time grand slam champion fall short once again at the year-end tournament, but he was confident of claiming a maiden ATP Finals crown. 

“I don’t want to think much beyond today... Given how I’ve felt, it’s difficult to think about the semis,” said Alcaraz.

“The good thing in this sport is that your game can feel very bad one day and very good the next.

"There have been many players who have lost the first match of the [Nitto] ATP Finals and ended up winning. I reached the semis last year after losing on the first day.

"Now I want to take it day by day, to feel better, and see how the next match is. I’ll approach it as best I can. Let’s hope things turn out well.”

Casper Ruud believes his 50th Tour-level victory of 2024 was one of his best after he upset third seed Carlos Alcaraz in his opening match of the ATP Finals on Monday. 

Ruud, who had registered just two wins since the US Open, sealed a 6-1 7-5 win in just 86 minutes against Alcaraz for his maiden Top 3 triumph on hard courts. 

The Norwegian reeled off five consecutive games from 1-1 to claim the first set at a canter but had to battle from the brink to secure a straight-set victory in Turin. 

Alcaraz had raced into a 5-2 lead in the second set but was unable to hold on, with Ruud roaring back to sit top of the early standings in the John Newcombe Group. 

"It's only one match, but it's one of the best wins of the season in terms of who I am playing and his ranking," Ruud said.

"I feel really happy, of course. I think we have seen Carlos play better tennis, but I took care of my chances. 

"I haven't been boosting with confidence in the last few months so it was a great win for me and I would like to get some more wins in Turin.

"I got a good start, I got a break early and in the second set I managed to turn it around with some good tennis at the end."

Ruud will next seek to earn a second win on Wednesday when he will face either Alexander Zverev or Andrey Rublev, who play later on Monday. 

Data Debrief: Ruud awakening

Although Alcaraz appeared below his physical best during Monday's encounter, Ruud took full advantage to continue his impressive streak against the very best in the world. 

The Norwegian's latest win saw his record against players in the Top 10 of the ATP rankings improve to 5-2, and he was a worthy winner in Turin. 

Ruud converted all four of the break points he was presented with, ending the contest with 10 unforced errors compared to Alcaraz's 26. 

After almost a month out of action, Jannik Sinner was delighted to shake off his rustiness with a straight-sets win over Alex de Minaur at the ATP Finals.

Playing on home soil in Turin, the Italian reeled off a 6-3 6-4 victory over De Minaur in 85 minutes, making a winning start to his bid to escape the Ilie Nastase Group, also containing Taylor Fritz and Daniil Medvedev.

It was Sinner's first match since he won the Shanghai Masters on October 13, but he overcame some early nerves to showcase his impressive power from the baseline.

Asked about the impact of his long wait between matches, Sinner said: "Considering that, I'm very happy. 

"I started off with some unforced errors. He was playing great in the beginning of the match, so I just tried to stay there mentally, knowing that hopefully at some point my tennis would arrive. It arrived quite early, and I started to return very well.

"My serve, for sure I have to improve if I want to win the next match. Against Taylor, today he played really well. Hopefully this can give me confidence for the next one."

Data Debrief: The man for the big stage

Sinner's victory over ninth-ranked De Minaur is his 13th against a top-10 player in ATP events this calendar year, having also done so in 2023.

He is just the fifth player aged 23 or under to reach that mark in back-to-back seasons since 1973, after legendary quartet Bjorn Borg (1977-79), Ivan Lendl (1980-82), Pete Sampras (1993-94) and Rafael Nadal (2008-09)

Taylor Fritz opened his ATP Finals campaign with a straight-sets victory over Daniil Medvedev, then acknowledged his fine serving display was the difference.

Fritz recorded a 6-4 6-3 victory over the fourth seed to make a flying start to his second appearance at the season-ending event in Turin.

With world number one Jannik Sinner and Alex de Minaur – who face off later on Sunday – also lurking in the Ilie Nastase Group, Fritz knew the importance of using his serve as a weapon.

He won 85% (33/39) of his first-serve points to Medvedev's 79% (30/38), also firing off nine aces and not committing a single double fault, compared to eight of each for the Russian. 

"The serve was a big part of it for sure," Fritz said after the match. "He's such a good returner. 

"You can make a lot of first serves, but if they are not very high quality, he just puts so many returns in the court.

"It was huge for me, I hit a lot of lines, a lot of spots to start out games. I got out of a lot of service games with no pressure. 

"Some of the ones we got tight in, I was either able to grind through the long rallies or get myself some free points."

Data Debrief: Fifty up for Fritz

Fritz's win made him just the fourth player to register 50 victories in ATP events this calendar year, putting him in an exclusive club.

Only Alexander Zverev (66), Sinner (65) and Carlos Alcaraz (52) have managed more such wins in 2024.

Carlos Alcaraz said he arrives at the ATP Finals with "a lot of motivation" and is looking to make his mark in Turin next week. 

Alcaraz, who claimed two grand slam titles at the French Open and Wimbledon this year, missed the event in 2022 after picking up an internal oblique muscle tear. 

The Spaniard was then beaten in straight sets by Novak Djokovic in the semi-finals, though the Olympic champion has since withdrawn from this year's tournament with an ongoing injury issue. 

Alcaraz, however, enters the year-end competition with a win-loss record of 52-11, with only Jannik Sinner (12) claiming more top 10 wins in 2024 than the 21-year-old (11). 

“Last year was a difficult end of the year for me,” Alcaraz said. “I could not play at my best.

"The last two matches here were pretty good matches for me, but the previous two, three tournaments I didn’t play at my best, so I realised I had to change a little bit at this time of the year, which I did this year.

“I come here a little bit different. I approach this tournament a little differently, knowing there are things I have to change if I am to have a good result here and go far.

"Last year I didn’t start well from the first matches. I will try to play at the same level and will try to play good tennis. I am coming here with a lot of motivation.”

Alcaraz was drawn in the John Newcombe Group at the ATP Finals alongside Alexander Zverev, Casper Ruud and Andrey Rublev.

He will start against Ruud on Monday, but might face the strongest competition in the group from Zverev, who claimed his seventh Masters 1000 title at the Paris Masters. 

Among the qualifiers for this year's event, Zverev (14) and Daniil Medvedev (11) are the only two to have recorded 10 or more match wins at the ATP Finals.

Alcaraz and Zverev have faced each other 10 times, winning five apiece, though Alcaraz has won the last two, including at Roland-Garros in the French Open showpiece.

“He is one of the toughest players in the world for sure,” Alcaraz said about Zverev.

“I think I return pretty well but he has a really big serve and plays unbelievable from the baseline, which makes him a really tough opponent to face.

“He has won more than 20 ATP Tour titles, lots of Masters titles. He wants a Grand Slam and I told him he is going to get it for sure.

"At the end of his career he will get at least one, let's see if more.

"He deserves it. He is a really hard worker. He has lifted the big trophies. I don’t like to face him because of his serves and shots, but I am trying to find the beauty of playing him.”

The end of the 2024 season is upon us, but before the ATP Tour wraps up until 2025, there is one final big tournament to come.

That season finale is, of course, the ATP Finals, and it kicks off in Turin on Sunday, with eight of the world's top players vying for the prize.

Jannik Sinner is already sure of his place as the year-end number one, but there could be movement in the rankings below him, with Alexander Zverev heading into the tournament as the newly minted world number two, ahead of Carlos Alcaraz.

Reigning champion Novak Djokovic withdrew on Monday, meaning for the first time since 2001, none of the "big three" (Djokovic, Rafael Nadal or Roger Federer) will feature at the ATP Finals.

Djokovic beat Sinner last year to claim his seventh ATP Finals title, which is the most times a player has won the competition.

Sinner, fresh from triumphs at Flushing Meadows and the Shangai Masters, heads to Turin as the favourite, with an eighth title on the line, but let's look ahead to the 2024 ATP Finals with Opta's pre-tournament facts.

Sin(ner) City

Sinner will not only be the firm fan favourite in Turin, he will always be the favourite to claim the crown.

The 23-year-old has already collected a Tour-leading seven titles this season, including the Australian Open and the US Open, and will be out to go one better following his loss to Djokovic in last year's final.

Six of Sinner's victories have come on hard court, with his triumph at the Halle Open the only exception. 

The Italian is only the fifth player aged 23 or under to win at least six Tour-level titles on hard courts in a calendar year after Jimmy Connors (1973), Ivan Lendl (1981), Pete Sampras (1994) and Federer (2004).

Since the ATP's redistribution of ranking points in 2009, only Djokovic (2015) and Nadal (2010) have clinched the year-end number one earlier in a season than Sinner in 2024.

He is out to become the seventh player to win the ATP Finals on home soil in the Open Era, and will be the player to beat in Turin.

Alcaraz and Zverev scrapping for second

Zverev comes into the tournament in excellent form, on the back of winning the Paris Masters.

His triumph in France not only saw him move into second place in the rankings, but also saw him claim his 66th match win, which is more than any other player in 2024 (Sinner is second on 65).

Among the qualifiers for this year's event, Zverev (14) and Daniil Medvedev (11) are the only two to have recorded 10+ match wins at the ATP Finals.

Zverev is only 27, but he is comparatively a veteran at the ATP Finals when stacked up against the other players to have qualified for this year's event. The German will be featuring at the tournament for the seventh time.

Since the rankings were first published in 1973, Boris Becker (four) holds the most wins over the world number one at the ATP Finals – Federer and Zverev have the next-most such wins, with three each.

Among players with multiple matches against the world number one at the ATP Finals, Zverev (3-2) is the only player to hold a winning record.

With Djokovic out of the picture, Alcaraz will be hoping to get back into the top two to end the year.

Only Sinner (12) has claimed more top 10 wins in 2024 than Alcaraz (11), whose last such win came against Sinner in Beijing in September.

Alcaraz is the only player to claim multiple wins over top-five ranked opponents on hard, grass and clay courts in consecutive seasons since the rankings were published in 1973. John McEnroe (1984) is the only other player to achieve the feat in a single year.

The other names in the hat

Who else will be looking for glory next week?

Medvedev comes into the ATP Finals ranked at number four in the world. Only two players won more matches at grand slams in 2024 than the Russian (18), and they are Sinner (23) and Alcaraz (19).

Taylor Fritz reached his first major final earlier this year, losing to Sinner at the US Open. Only two players - Zverev and Sinner - have won more matches on the Tour in 2024 than the American, who has an impressive 49-21 record.

After qualifying for the 2022 ATP Finals, Fritz will become the first American to make multiple appearances at the event since Andy Roddick (2003, 2004, 2006, 2008 and 2010).

Casper Ruud is one of only three players, along with Sinner (eight) and Alcaraz (five), to have reached at least five ATP finals this year.

Alex de Minaur, meanwhile, will become the first Australian to appear at the ATP Finals since Lleyton Hewitt 20 years ago.

Hewitt went on to reach the final, so there is a good omen there for his compatriot.

Novak Djokovic has pulled out of the ATP Finals, which start in Turin later this week.

Djokovic pulled out of the Paris Masters last month, and the world number five will now not feature in the season-ending tournament.

The 37-year-old, who lost to Jannik Sinner in the Shanghai Masters in his last competitive appearance, is sat on 99 ATP Tour-level titles, and his wait for a 100th victory will now roll into 2025.

Djokovic confirmed on Tuesday that he would not be participating in the ATP Finals.

"I was really looking forward to being there, but due to ongoing injury I won't be playing next week," Djokovic said on social media.

"Apologies to those who were planning to see me. Wishing all the players a great tournament. See you soon!"

Jannik Sinner, Alexander Zverev, Carlos Alcaraz, Daniil Medvedev and Taylor Fritz have all qualified for the tournament.

Andrey Rublev, Casper Ruud and Alex de Minaur are the three players contesting for the remaining two spots.

Alexander Zverev downed Holger Rune at the Paris Masters to reach his first hard-court final of the season. 

Zverev recovered from failing to serve out the match at 5-4 in the second set, resisting a late fightback from Rune to earn a 6-3 7-6 (7-4) victory in the French capital. 

The German, who hit 25 winners and won 84% of his first-serve points, also climbed above Carlos Alcaraz in the ATP rankings after securing his 65th win of the season. 

He is a former finalist in Paris, having lost in the title match in 2020 to Daniil Medvedev, but will be hoping to clinch a seventh ATP Masters 1000 crown this time around. 

Zverev will face either home favourite Ugo Humbert or former champion Karen Khachanov in Sunday's showpiece.

Data Debrief: Zverev one away

Zverev's triumph saw him reach a 12th ATP Masters final. Since the format's inception in 1990, the German surpassed Boris Becker (11) for the seventh-most in tournament history.

It was also his 65th win of the season, equalling Jannik Sinner (65) for the most ATP match victories of any player so far this year. 

Alexander Zverev became just the third active player to reach 20 ATP Masters 1000 semi-finals on Friday at the Paris Masters after his victory over Stefanos Tsitsipas. 

Zverev, who is chasing his seventh Masters 1000 title and second of the season, needed an hour and 41 minutes to secure a 7-5 6-4 triumph over his Greek opponent. 

The pair exchanged blows early on, but it would be Zverev who claimed the decisive point, breaking Tsitsipas' serve in the 11th game.

Zverev then saved an immediate break point in the following game, but was able to close out the opener to gain the early advantage in the French capital. 

A break of serve came much sooner for Zverev in the second set, winning the third game to put himself in the driving seat for the remainder of the contest. 

He ended the encounter in style, serving three consecutive love games to seal his progression to the final four, where he will face either Holger Rune or Alex de Minaur. 

Data Debrief: Alexander the Great

Zverev has now reached his 20th ATP Masters 1000 semi-final, equalling Andy Roddick for the seventh-most since the format’s introduction in 1990.

He is just the eighth player in history to reach 20 ATP Masters 1000 semi-finals. Zverev joins Novak Djokovic (78), Rafael Nadal (76), Roger Federer (66), Andy Murray (33), Andre Agassi (32), Pete Sampras (31) and Roddick (20) to hit that total. 

Zverev also became the first player born in the 1990s to earn 100 Top 20 wins (100-101). Daniil Medvedev, born in 1996, is second, holding a 99-73 record.

World number two Carlos Alcaraz admitted that he was "not up to the level" after a defeat to Ugo Humbert saw him crash out of the Paris Masters in the third round. 

Humbert, ranked 18th in the world, posted a 6-1 3-6 7-5 win against the second seed in two hours 17 minutes to reach the quarter-finals of the ATP Masters 1000 event in the French capital. 

"It was a very intense match. I started with some doubts about my game," said 21-year-old Alcaraz after the surprise defeat. 

"Against a player who attacks whenever he can, who hits very aggressively at the slightest opportunity, it wasn't easy to get into the match.

"I was not up to the level he displayed. Ugo's performance was really high. The way he hits the ball is incredible."

Alcaraz had his sights set on a fifth title of the season in Paris but will move on to the Nitto ATP Finals in Turin next, with the season finale to be played from November 10 to 17. 

Humbert, meanwhile, will continue his hunt in the Paris Masters as he preps up to battle Australia's Jordan Thompson for a spot in the semi-finals. 

World number two Carlos Alcaraz crashed out of the Paris Masters after an upset at the hands of 15th seed Ugo Humbert in the third round. 

Alcaraz was aiming for a fifth title of the season in the French capital, but it was the world number 18 who emerged as 6-1 3-6 7-5 winner in two hours 17 minutes. 

The Spaniard had no answer for Humbert in the first set, but fought back to level the proceedings in the second. 

The third set was a tight affair, but it was 26-year-old Humbert who prevailed to take it 7-5 and reach the last eight at the ATP Masters 1000 event. 

Humbert, looking for his third title of the season, will next face Australia’s Jordan Thompson, who progressed to the quarter-final by defeating Adrian Mannarino. 

Alexei Popyrin upset fourth-seeded Daniil Medvedev at the Paris Masters to continue his fine year on the ATP Tour, securing his third career win over a top five opponent.

Popyrin, who improved to 26-21 for 2024 with his latest win, emerged a 6-4 2-6 7-6 (7-4) victor in just under two-and-a-half hours in the French capital. 

The Australian, however, started poorly in the first set, with Medvedev earning an early break in the third game, only for Popyrin to claim the next three in a row. 

Popyrin then missed four chances to close out the eighth game, but held his nerve to take the opener despite some late pressure from his Russian opponent. 

But Medvedev responded emphatically in the second, managing back-to-back break points before taking the enthralling encounter to a decider. 

The pair continued to trade blows in the third set and could not be separated, with a tie-break deciding who would face either Giovanni Mpetshi Perricard or Karen Khachanov in the last 16. 

Popyrin let slip a 4-1 lead in the deciding set, but held his nerve to deal Medvedev his third consecutive opening round loss in Paris. 

Data Debrief: Popping in Paris

Popyrin finally got the better of Medvedev, having lost his previous three matches against him at Wimbledon in 2019, the Australian Open in 2020 and the Miami Open in 2021. 

In defeating Medvedev, Popyrin is the second Australian after Mark Philippoussis to register multiple wins against a top-five player at the Paris Masters. 

The Australian had previously beaten Stefanos Tsitsipas in 2021, who was ranked as the world number three.
