Jannik Sinner defeated Carlos Alcaraz to defend his ATP Finals title in Turin and extend his imperious indoor hard-court winning run to a 31st match.
The young rivals were meeting in their sixth final of the season and Sinner claimed just his second win over Alcaraz in that spell to avenge his defeat in the US Open final two months ago.
After a tight first set, delayed by 11 minutes due to a medical emergency in the crowd, Sinner raised his level to take the decider. Alcaraz received strapping on a right hamstring injury but broke Sinner’s serve for the first time this week in the opening game of the second set.
Sinner broke back thanks to a fortuitous return and finished the match in dominant fashion, ensuring he has now won two ATP Finals in a row without dropping a single set. The 24-year-old Italian also becomes the youngest player to win back-to-back ATP Finals crowns since Roger Federer in 2004.
And after a season where Sinner won the Australian Open and Wimbledon and Alcaraz won Roland Garros and the US Open, the Spaniard warned: “It’s time to rest, hope you’re gonna be ready for next year because I will be ready for more finals against you!”
Carlos Alcaraz provides update as ATP Finals injury risks Davis Cup hopes
Carlos Alcaraz refused to blame a hamstring injury for his defeat to Jannik Sinner in the ATP Finals and is planning on travelling to Bologna to take part in the Davis Cup finals with Spain this week.
The World No 1 took a medical timeout towards the end of the first set and received heavy strapping on his right leg as Sinner won 7-6 7-5 to defend his ATP Finals title and extend his dominant form on indoor hard-courts.
Alcaraz is set to be part of a Spain team that looks to win the Davis Cup, which starts on Tuesday, from an Italy side who will be without Sinner, who announced last month that he will instead start his off-season early.
‘There’s no better ending to the season’
Jannik Sinner, speaking to Sky Sports, after winning the ATP Finals title in Turin:
“There is for sure no better ending for the season. It has been an incredible season, so many ups, difficult moments obviously for various reasons, finishing the season here in Turin in front of the home crowd against the best player in the world, my biggest rival, it’s amazing.
“The level was very, very high, especially the first set. The tiebreak was a key moment I got lucky when I broke him back, which gives you a bit of confidence and belief and I’m extremely happy to finish the season like this.”
