Jannik Sinner, Novak Djokovic and Carlos Alcaraz are set to be the marquee names at the Six Kings Slam in Riyadh, Saudi Arabia, scheduled for Oct. 21-24. The event brings together some of the biggest stars in men's tennis, with world No. 1 Sinner joined by 24-time major champion Djokovic and seven-time major winner Alcaraz.

Sinner returns to the exhibition after winning last year's title. In that final, he defeated Alcaraz in straight sets and collected a record $6 million prize, a result that added extra attention to the event and raised expectations for this year's edition.

The presence of Sinner, Djokovic and Alcaraz gives the Six Kings Slam a high-profile lineup built around three of the sport's most recognizable names. Riyadh has become an increasingly notable stop for major sports events, and this tournament is again positioned as a headline tennis attraction on the calendar.

With Sinner coming in as the defending champion and Alcaraz looking to reverse last year's result, Djokovic's inclusion adds another major storyline. Their participation ensures that the Six Kings Slam will again be closely watched by tennis fans when play begins in October.
