Jannik Sinner is set to immediately lose part of his prize money after defeating Carlos Alcaraz in straight sets to win the ATP Finals tournament.
Alcaraz and Sinner renewed their rivalry at the top of tennis with a memorable meeting in the ATP Finals on Sunday, with Sinner winning 7-6, 7-5 in Turin.
The Italian needed a tiebreak to win the first set, winning it by seven points to four.
In the second set, he immediately had his serve broken by Alcaraz, but broke back to level at 3-3.

Alcaraz was then 40-30 up to level the set at 6-6 and force another tiebreak, but Sinner won three consecutive points to secure victory in dramatic fashion in the country of his birth.
The new titans of tennis have met 16 times in their career, putting on clinics in the biggest tournaments in the world since their first encounter in 2021.
Alcaraz has the edge on the overall record though, winning the Grand Slam trilogy by emerging victorious in the US Open final, following up his triumph in Roland Garros and avenging his loss at Wimbledon.
Last year Sinner went all the way and defeated Taylor Fritz 6-4, 6-4 without dropping a set, taking a cool $4,881,100 in prize money.
This time around in Turin, the figure for the winner was bumped up to £3.86 million to give the richest payout in the history of the year-end tournament.
The record sum was generated because both players, who squared off for the sixth time in 2025, advanced through their group without losing a game in a perfect run.
How much prize money will Sinner receive?
While the payout for winning the crunch clash at the Inalpi Arena, Sinner will not receive all of the aforementioned winnings because tax comes into play.
Italy taxes athletes who are non-residents with a withholding tax that is normally around 30% - therefore bringing a deduction of £1.34 million to bring the final winnings payment down to £2.52 million.
Sinner is from Italy but has resided in Monte Carlo, Monaco since 2020 and therefore does not appear liable to pay tax on his earnings due to not having fiscal residence in his country of birth.
He is essentially considered a foreign athlete and pays the 30% but being a non-French resident, he would avoid paying personal income tax on his prize money in Monaco.
Between them, Alcaraz and Sinner have made close to £100 million in prize money following their excellent performances on the court.
