Jannik Sinner has decisively put to rest any speculation about proposing to his model girlfriend, Laila Hasanovic, following his impressive showing at the ATP Tour Finals.

On Sunday, Sinner emerged victorious in the latest chapter of the ‘Sincaraz’ rivalry for 2025, defeating the top-seeded Spanish player 7-6 (4), 7-5. This marked their sixth encounter this year, as both players continue to dominate the men’s tennis scene.

Sinner successfully defended his title in front of his enthusiastic home crowd in Italy, securing only his second win over Alcaraz this year after their clash in the Wimbledon final.

The Italian tennis star went public with his relationship with Danish model Laila Hasanovic, who has previously been linked to Mick Schumacher, earlier this year.

“It was an incredible season,” Sinner remarked. “Ending it like this, in front of my Italian supporters, is truly special for me.”

While Sinner’s performance on the court earned him high praise from tennis experts, questions arose about his relationship when Hasanovic posted a mysterious photo of a ring on social media over the weekend.

‘The ring Laila showed on social media? Did I have a hand in it? No, no,’ he said.

Alcaraz had already secured the year-ending No. 1 ranking and was contesting his first final at the event for the year´s top eight players.

Alcaraz still leads his career meetings with Sinner, 10-6.

Sinner and Alcaraz have met in the last three Grand Slam finals. Alcaraz beat Sinner in a fifth-set tiebreaker to win the French Open; Sinner gained a measure of revenge at Wimbledon; then Alcaraz again came out on top at the U.S. Open.

They also clashed this year in the Italian Open final (won by Alcaraz) and the Cincinnati Open final (won by Alcaraz when Sinner retired due to illness).

‘I hope you are going to be ready for next year because I will be ready to hopefully play more finals against you,’ Alcaraz said during the trophy ceremony.

To which Sinner added that he hopes they have ‘great, great battles ahead of us.’

Sinner also won the Australian Open – beating Alexander Zverev in the final – so he and Alcaraz each won two majors this year.

In all, Alcaraz has won six majors and Sinner has won four.

Already early in the first set, the pro-Sinner crowd chanted its customary ‘Ole, Ole, Ole, Ole; Sin-ner, Sin-ner.’

One fan even held up an image of Sinner depicted as a saint.

Sinner saved a set point at 5-6 in the tight first set with a big second serve that Alcaraz couldn´t return. Then the Italian took control of the tiebreaker by running down a drop shot and responding with a lob that led to an overhead put away.

‘I´m extremely happy with how I handled the situation,’ Sinner said of saving the set point.

Added Alcaraz, ‘He came up with a second serve 185-190 kph (115-118 mph) that surprised me.’

Alcaraz had his right thigh treated by a trainer on two occasions – and got it wrapped after the first set.

‘Didn´t affect me too much, to be honest, because I could run well,’ Alcaraz said.

Alcaraz broke Sinner´s serve in the opening game of the second set but Sinner then evened it at 3-3.

Sinner then got the crowd going again in the next game when he won a long rally and held his finger to his ear – signaling for more noise inside the Inalpi Arena.

Sinner broke Alcaraz again to close it out when the Spaniard missed a backhand wide – then fell down to the court on his back in relief.

But Sinner emphatically quashed rumours he has popped the question to his new girlfriend

‘It was a huge emotion,’ said Sinner, who was banned for three months earlier in the year after settling a doping case.

Alcaraz led 28-25 in winners but also had more unforced errors, 26-24.

Sinner said he wanted to improve his serve after the loss to Alcaraz at the U.S. Open and he led 8-5 in aces but also had five double-faults to Alcaraz´s none.

It was Sinner´s 10th straight win at the finals stretching back to his loss to Novak Djokovic in the 2023 final. What´s more is that Sinner hasn´t lost a set in that stretch.

Sinner also extended his winning streak on indoor hard courts to 31 matches.

In the doubles final, Harri Heliovaara and Henry Patten beat Joe Salisbury and Neal Skupski 7-5, 6-3.
