ATP Finals 2025: Jannik Sinner victory in Turin keeps Carlos Alcaraz on his toes for 2026

A year which belonged to Jannik Sinner and Carlos Alcaraz had to finish this way.

Another pulsating contest between the preeminent pair on the men's tour - this time with the season-ending ATP Finals trophy at stake - was a fitting conclusion.

For the victorious Sinner, the win perhaps mattered that little bit more. The way the mild-mannered Italian collapsed on his back in celebration after championship point seemed to indicate it did.

"I am very happy. It was a tough match, but it means a lot to me ending the season like this," said 24-year-old Sinner.

Not only did the four-time major champion defend the prestigious trophy in front of passionate home support in Turin, concluding a tumultuous season where he won the Australian Open and Wimbledon but spent three months on the sidelines after being banned for failing two doping tests.

The straight-set success also ensured Sinner kept Alcaraz on a leash.

While the rivals have equally shared the four Grand Slam trophies this season, there was a feeling that Alcaraz had started to gain a slight upper hand in a rivalry which has illuminated the sport.

The 22-year-old Spaniard had already clinched the year-end world ranking going into Sunday's final, while a dominant performance in the US Open's showpiece match gave him a 10-5 lead over Sinner in their head-to-head record.

After losing in New York, Sinner made a revealing remark when he conceded he needed to leave his "comfort zone" in order to truly test Alcaraz.

And, just like he did by beating Alcaraz to the Wimbledon title only 35 days after defeat in their epic French Open final, Sinner showed his remarkable ability to bounce back mentally from tough defeats.

Even his opponent can see it.

"After every loss - you don't have many - you come back stronger," said Alcaraz in his on-court runners-up speech.

"You've had a great year and I hope you will get some rest and be ready for next year - because I will be ready."

As he spoke, Alcaraz flashed the infectious smile which has helped endear him to crowds globally.

Make no mistake, though, there was plenty of intent behind the words.

You can bet Alcaraz and his team - led by former world number one Juan Carlos Ferrero - will be forensically analysing what they can improve when they hit the practice courts.

And that is one of the defining factors of this compelling rivalry: both players pushing each other to greater heights.

When one loses, it leads to some deep soul-searching and a focus on what can be improved - particularly when they next meet each other.

"This is what we get so excited about," said former British number one Laura Robson, who was analysing the match for Sky Sports.

"They bring the best out in each other, they know they have to push each other and improve constantly to outdo one another."

Former world number four Tim Henman said the level of Sinner and Alcaraz is "frightening" for their rivals.

"They are pushing each other higher and higher, better and better, making more improvements, and the gap is wide," he added.

Since the US Open, Sinner has focused on being more aggressive with his serving - which led to him being broken only once during his five matches in Turin - and playing with more variety.

Both facets were evident against Alcaraz.

When Alcaraz had a chance to win the first set at 6-5 on Sinner's serve, the Italian nervelessly sent down a 117mph second serve to his opponent's backhand to save the break point.

A pair of unreturnable first serves followed and enabled Sinner to force a tie-break which he then controlled.

In the second set, with Alcaraz hampered by a hamstring injury which required strapping, Sinner began to use more drop shots and it was notably one which saved a break point in the seventh game.

Breaking Alcaraz again in what proved to be the final game meant Sinner lifted the trophy without dropping a set.

"You are definitely a player I look up to," Sinner, who stretched his unbeaten record indoors to 31 matches, told Alcaraz in his winner's speech.

"[You give me] a lot of motivation - I need this - in every practice session with a big, big purpose.

"I hope to see you again next year with, hopefully, great, great battles ahead of us."

The tickertape had not even settled on the Turin court.

Yet the platitudes exchanged by the pair - who appear to have a genuine warmth in a relationship - indicated they are already looking forward to locking horns again in the 2026 season.

A lot of tennis fans are also licking their lips about seeing Sinner and Alcaraz going head-to-head again - and lamenting it will not happen again for at least another couple of months.

A rendezvous in the Australian Open final, with Sinner looking to defend his Melbourne crown and Alcaraz aiming to become the youngest man to complete the career Grand Slam, would be their dream.

On the evidence of this season and this latest encounter, few would bet against it.
