The future faces of tennis squared off on Saturday in Saudi Arabia. Jannik Sinner defeated Carlos Alcaraz in three sets in the finals of the Six Kings Slam: 6-7 (5), 6-3, 6-3.

Jannik Sinner beat Carlos Alcaraz for the championship in the Six Kings Slam exhibition event after Novak Djokovic topped Rafael Nadal for third place in what might have been the final match in one of tennis' great rivalries.

Saudi Arabia’s push into tennis took off last year with its first ATP Tour event –- the Next Gen ATP Finals in Jeddah –- and exhibition matches pitting Djokovic against Alcaraz and Aryna Sabalenka against Ons Jabeur.

Jannik Sinner is the Six Kings Slam champion! World no. 1 faced world no. 2 Carlos Alcaraz in the title clash in Riyadh and produced a 6-7, 6-3, 6-3 victory in two hours and 20 minutes, taking home the biggest prize money in tennis history!

Rafael Nadal starts his pre-retirement farewell tour against Carlos Alcaraz on Thursday at the Six Kings Slam, and Novak Djokovic faces Jannik Sinner at an exhibition event that awards money but no ATP ranking points and is Saudi Arabia's latest foray into tennis.

Novak Djokovic spoilt the Rafael Nadal retirement party by beating the Spaniard in straight sets in their Six Kings Slam third-place match. The Riyadh exhibition played host to potentially Nadal’s last ever singles match and his final ever game against longtime rival Djokovic, who won the match 6-2, 7-6.
