Novak Djokovic delivered a masterclass to beat Carlos Alcaraz in the latest instalment of their burgeoning rivalry to reach the ATP Finals showpiece.
The Serb will aim for a record seventh title on Sunday after a 6-3 6-2 win put him through to face Italian Jannik Sinner in Turin.
Sinner became the first Italian to make the season-ending final with a 6-3 6-7 (4-7) 6-1 win over Daniil Medvedev.
In doubles, Britain’s Joe Salisbury and American Rajeev Ram reached the final.
The defending champions beat French-Mexican pair Edouard Roger-Vasselin and Santiago Gonzalez 7-6 (7-5) 3-6 10-7, and will face Argentina’s Horacio Zeballos and Marcel Granollers of Spain for the title on Sunday.

Djokovic has won three of the season’s Grand Slams, beating Alcaraz in the French Open semi-finals, while Alcaraz won the other major by overcoming the Serb in the Wimbledon final.
The pair traded the world number one ranking through the season but Djokovic sealed the year-end top spot earlier this month for a record eighth time, and his performance on Saturday underlined why he remains the player to beat.
