TENNIS SHOWDOWN: CARLOS ALCARAZ AND JANNIK SINNER FIGHT FOR WORLD NO.1
Jannik Sinner reclaims the world No. 1 ranking after winning the Paris Masters. The battle with Carlos Alcaraz for the year-end top spot now intensifies heading into the ATP Finals in Turin.
Jannik Sinner has returned to the top of the world rankings after winning consecutive ATP Tour titles.
Following his victory in Vienna last weekend, Sinner defeated Felix Auger-Aliassime at the Paris Masters to win his fifth ATP championship of 2025 and to reclaim the top spot in the rankings for the first time since the US Open.
Although Carlos Alcaraz still leads going into the ATP Finals, the Italian's prospects of securing back-to-back year-end world No. 1 finishes have suddenly increased. Here, we examine how the matchup between the two is developing.
As of right now, Alcaraz's unexpected loss in the second round and Sinner's march to his fifth Masters 1000 triumph in Paris have put the Italian back at the top of the rankings on Monday.
Alcaraz is now behind him in the ATP Rankings with 11,250 points, while he has 11,500 points.
Alcaraz still holds a sizable lead in the ATP Race to Turin, which only tracks points earned in 2025, despite losing his position as the world No. 1 ranking.
With Sinner on precisely 10,000 points following his romp to the victory in Paris, the Spaniard has amassed 11,050 points this season.
Alcaraz is in a strong position to win the year-end No. 1 rating, even if the gap has narrowed considerably over the last week.
In Turin, what does Alcaraz need?
Alcaraz will once again take Sinner's spot as the world No. 1 when the points from the ATP Finals from the previous year are eliminated before this year's competition.
Alcaraz will drop just 200 points despite winning just one group stage match a year ago, while Sinner will drop back to 10,000 points ahead of the event after securing a full 1,500 ranking points for an undefeated run to the final in 2024.
Alcaraz will now have 11,050 points as the world number one and be very close to finishing at the top of the rankings for the first time since 2022.
Sinner would return to 11,500 points following Turin, 450 points higher than Alcaraz's pre-Turin total, if he were to win the title without losing.
This indicates that the Spaniard may easily secure the top spot at the conclusion of the year with just 451 points.
Every Turin round-robin game is worth 200 ranking points, so if Alcaraz wins every group stage, he will have 600 points, which will guarantee him the top slot at the end of 2025, regardless of how he and Sinner perform.
Alcaraz would need to hope he advances and wins his semi-final in order to gain an additional 400 points if he were to achieve 400 points for a 2-1 record in the round-robin round.
If Alcaraz advances and wins in the semi-final, he could still earn the year-end No. 1 ranking even if he just wins one group stage match.
In Turin, what does Sinner need?
For Sinner to have a genuine chance at ending 2025 as the year-end No. 1, he should ideally win the title again without dropping a match.
If Alcaraz were to win two group stage matches and not advance, or win two group stage matches and then lose in the semi-final, the Italian would secure the year-end No. 1 ranking if he were to win the title with a perfect 1,500 points.
Sinner would need Alcaraz to either win one group stage match and lose his semi-final, or win one group stage match and not advance, if he were to win the title after a 2-1 group record and 1,300 points.
In the end, the Spaniard would only need one round-robin victory to secure year-end No. 1 if the Italian lost two group stage games and won the title, earning 1,100 points.
To have any chance of securing the year-end No. 1 finish, Sinner needs to win the title; any other outcome would ensure Alcaraz would take first place.
BREAKING: AUSTRALIAN OPEN SEEDING AT RISK! CHECK THE NEW 18-TOURNAMENT RANKING RULE NOW
The 2026 ATP season begins with a major rule change. Rankings now count only 18 tournaments, causing points to drop for the Top 10.
The 2026 ATP Tour season kicks off with the United Cup this Friday. Everyone's watching to see what happens in men's tennis this year.
There's a ranking rule change that started late in 2025 that everyone will be dealing with.
Here’s a breakdown of the change and who it's impacting:
What's the New Rule?
Before 2026, a player's ATP ranking could include points from 19 tournaments: the four Grand Slams, the eight mandatory Masters 1000 events, and their next seven best results.
These could be from the Monte Carlo Masters, ATP 500, ATP 250, or Challenger events. Qualifying for the ATP Finals was a bonus.
Now, only 18 events count. Rankings will only include the four Grand Slams, eight mandatory Masters events, and a player's six best results, plus the ATP Finals if they qualify.
Also, the top 30 players only need to play four ATP 500 events, instead of five.
Who's Affected in the Top 10?
This change took place recently, and seven players in the top 10 lost points. Their positions stayed the same this time, except for the players who are stated.
Carlos Alcaraz, Jannik Sinner, and Jack Draper were not affected.
Alexander Zverev lost 50 points, Novak Djokovic dropped 10, Felix Auger-Aliassime lost 55, Taylor Fritz dropped 50, Alex de Minaur lost 55, Lorenzo Musetti dropped 50, and Ben Shelton lost 10 points.
What About the Rest of the Rankings?
The top players are mostly okay, but the further down the rankings you go, the more change you'll see.
In the top 20, Jiri Lehecka is the only one impacted. He lost 10 points and fell to No. 18. Karen Khachanov moved up to 17th.
Luciano Darderi and Tallon Griekspoor switched places and are now ranked 25th and 26th. These were the only changes in the top 30.
Outside the top 30, there were bigger moves.
Jaume Munar jumped three spots to No. 33, and Corentin Moutet moved up to 34th. Brandon Nakashima and Stefanos Tsitsipas each fell two spots.
Now ranked 35th and 36th, Nakashima and Tsitsipas might have a harder time getting seeded for the Australian Open.
Pablo Carreno Busta dropped the most, falling from 89th to 93rd.
IMMEDIATE: SHOCKING DETAILS BEHIND CARLOS ALCARAZ-FERRERO SPLIT; WILL HE JOIN RIVAL JANNIK SINNER
World No. 1 Carlos Alcaraz has shocked tennis by splitting with Juan Carlos Ferrero. Learn the real reason behind the breakup.
Tennis fans were shocked when Carlos Alcaraz and his long-time coach, Juan Carlos Ferrero, split. Ferrero has now said whether they've talked since.
Even though Alcaraz is only 22, his time with Ferrero is one of tennis' best. The 2003 French Open champ started coaching Alcaraz, who was a young, promising player in 2019.
With Ferrero's help, Alcaraz became a superstar and one of the most exciting players to watch. He's won six Grand Slams and finished 2025 as the world's top player, ahead of Jannik Sinner.
The only major title they didn't win together was the Australian Open. Even though it's still a few weeks away, people recently saw Alcaraz's outfit for the 2026 tournament in Melbourne. It's bright and colourful.
Alcaraz had a great 2025, winning two more Grand Slams, so the split was even more surprising. It sounds like disagreements between Ferrero and others close to Alcaraz caused the change.
In an interview, Ferrero answered a question everyone's been asking: Have he and Alcaraz been in touch since they stopped working together?
We haven't talked yet because he needs to relax so he can train. Once things calm down, we'll talk, and everything will be fine.
Ferrero's nice words about Alcaraz suggest they'll talk again. He thinks they can still be friends after all they've achieved.
I've learned a lot from Carlos. He's a kid with amazing charisma. He's always loyal and honest, tells the truth, and works really hard. I'm happy because once things settle, I'm sure we'll keep talking, remembering all the things we did together, and stay friends.
It must be tough for Ferrero not to be coaching Alcaraz after working so hard to make him one of the best. Taking some time before talking to the 22-year-old might also be good for him.
Juan Carlos Ferrero was also asked about coaching Jannik Sinner after splitting from Carlos Alcaraz.
Since 2024, one of Ferrero's main jobs has been helping Alcaraz figure out how to beat Jannik Sinner. Together, they've won every men's singles Grand Slam in the last two seasons.
Now that Ferrero isn't Alcaraz's coach, he was asked if he'd consider joining Sinner's team, which would be a huge change in tennis.
Ferrero didn't say no. Instead, he said he needed time to get used to not coaching Alcaraz. Sinner is still coached by Simone Vagnozzi and Darren Cahill, after Cahill changed his mind about retiring at the end of 2025.
