Jannik Sinner capped off an incredible year by securing the ATP Finals title, defeating Taylor Fritz with a score of 6-4, 6-4 in front of his home crowd in Turin. This victory marks Sinner's third major title of the year, having previously won both the Australian Open and the US Open, and he has also achieved the year-end No. 1 ranking. With this win, Sinner made history as the first Italian to claim the ATP Finals trophy, accomplishing the feat without dropping a single set throughout the tournament—a milestone last achieved by Ivan Lendl in 1986.

Alexander Zverev showcased his impressive form at the ATP Finals, advancing to the semi-finals in Turin with a solid 7-6 (5), 6-4 victory over Spanish world No. 3, Carlos Alcaraz. Following his triumph at the Paris Masters, Zverev, the second seed, has now extended his winning streak to eight matches, having previously defeated Alcaraz, Casper Ruud, and Andrey Rublev in Turin. In the upcoming semi-final, Zverev will face Taylor Fritz, who has had the upper hand in their two Grand Slam encounters this year.
