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.

Jannik Sinner stayed on course to defend his ATP Finals title, while Felix Auger-Aliassime claimed the last semi spot.

Canada’s Felix Auger-Aliassime reached the last four of the ATP Finals with a 6-4 7-6(4) round-robin win over two-time winner Alexander Zverev on Friday, and Jannik Sinner extended his indoor hardcourt unbeaten run by beating American Ben Shelton.

Germany’s Zverev and Auger-Aliassime both defeated Shelton and lost to Sinner to set up a winner-takes-all clash for the runners-up spot in the Bjorn Borg Group, and the Canadian clinched a place in Saturday’s semifinal against world number one Carlos Alcaraz.

“You want to be in the final, but I’ll have to go through a great player to do that,” Auger-Aliassime said.

“I will take my chance if I have it.”

Zverev was left to rue his failure to take any of his seven break points against Sinner, and it was a similarly frustrating story against the Canadian.

The German held break points in both sets but again could not make them count, and the Canadian broke Zverev at 5-4 up to take the first set, before going on to win the second set tiebreak.

Auger-Aliassime was put under pressure in the opening set, saving break points at 2-2 and 4-4, while Zverev came back from 0-40 down only to lose serve and hand the Canadian the set.

Zverev spent much of the second set gesturing to his team, with Auger-Aliassime winning his first two service games to love before both players were guilty of throwing away chances to break.

Auger-Aliassime let slip a 2-0 lead in the tiebreak, but when Zverev stepped up to serve at 4-5, the Canadian came through to earn consecutive minibreaks and send the German home.

Sinner stays unbeaten

Sinner is unbeaten in 29 matches on indoor hardcourt after a 6-3 7-6(3) victory over Shelton in their dead rubber round-robin match.

There was a relaxed atmosphere in the Inalpi Arena as the Italian had already secured top spot in the group and a semifinal against Alex de Minaur.

Shelton was broken in the opening and closing games of the first set, unable to take advantage of a break point at 2-1 down, while Sinner was always capable of pulling out an ace at the crucial time, hitting two in that fourth game to hold serve.

The American put up more fight in the second set, serving to love on three occasions, rescuing a match point at 5-4 down and forcing Sinner into a tiebreak for the first time in the last two editions of the season-ending championships, before the Italian sealed the win.

Sinner’s chances of ending the year as world number one evaporated on Thursday when Alcaraz completed a clean sweep in the Jimmy Connors Group with a win over Lorenzo Musetti, leaving little at stake against Shelton apart from his unbeaten run.

Before Sinner and Shelton emerged, Alcaraz was presented on court with the ATP year-end world number one trophy, which the Italian won last year, and the pair may yet do battle one last time in 2025 in Sunday’s final.

“It’s a pleasure being the number one of the world. It’s something that I’m working really hard for every day. It is a goal, to be honest,” Alcaraz said.

“For me, it’s a great achievement. It means the world to me and I’m just really proud and happy.”

Auger-Aliassime quickly found himself 4-1 down in the first set, with Shelton putting the serve and volley to good use, but he broke back as his opponent served for the set.

However, a poor service game handed the initiative – and the opener – to fifth seed Shelton.

Shelton had the only break point of the second set but an increasingly confident Auger-Aliassime saved it, before clinching the tie-breaker on a wild double fault from Shelton.

A tight third set was also decided on the Shelton serve, with Auger-Aliassime converting his third match point.

“He was playing much better than me at the start,” Auger-Aliassime said.

“It was a weird start, but as the match went on I was finding ways to put returns in the court.”

Jannik Sinner begins his ATP Finals title defence with victory against Felix Auger-Aliassime on home soil in Italy.

Italy’s Jannik Sinner began his bid to retain the ATP Finals title with a resounding 7-5, 6-1 win over injury-hit Canadian Felix Auger-Aliassime in their round-robin clash at a packed Inalpi Arena in Turin on Monday.

The pair were meeting for the fourth time since August, and eight days after their last clash, with the outcome the same as Sinner eased into the match before overpowering Auger-Aliassime, who needed medical attention during the second set.

Sinner extended his incredible indoor hardcourt winning streak to 27 matches, his last defeat on the surface coming against Novak Djokovic in the 2023 ATP Finals decider.

The 24-year-old is also in a battle with Carlos Alcaraz to end the year as world number one. Sinner must retain his title in Turin to have any chance, while the Spaniard can secure the prize by winning two more matches after victory in his opener.

Sinner began with intent by winning the first game to love and went on to give up just three points on serve in the opening set while forcing five break points, displaying an impressive mixture of sharp backhand and forehand shots down the line.

Auger-Aliassime hung in, smashing eight aces to Sinner’s one during the first set, often at just the right time as he saved four break points, but the Italian came through when it mattered, breaking to win the set.

“It was a very tough match until 6-5. I had some chances to break,” Sinner said.

“He played some very aggressive tennis, so I’m happy to overcome a very tough test today. Obviously, winning the first match is very important in this competition and this format.”

Sinner stormed into a 3-0 lead in the second, and his opponent took a medical timeout for a problem in his left calf.

“I hope it’s nothing too serious,” Sinner said.

“I wish him obviously a very speedy recovery, and hopefully he is back to 100 percent physically.”

Auger-Aliassime saved two break points to avoid losing touch completely before Sinner sank the Canadian with another break to leave the Italian serving for the match, which he did in style, hammering home an ace to clinch the win.

While the Canadian struggled in the second set, Sinner began to enjoy himself, playing some deft drop shots to the delight of his home crowd, who rose to their feet to acclaim the win.

On Sunday, German Alexander Zverev beat American Ben Shelton 6-3, 7-6(6) in the other Bjorn Borg Group match. All four players in the group will meet each other, with the top two qualifying for the semifinals.

Tuesday’s action features the Jimmy Connors Group, where Alcaraz takes on last year’s finalist Taylor Fritz, with both players on one win each, and Italian Lorenzo Musetti faces Australian Alex de Minaur.
