The 2026 edition of the Six Kings Slam will proceed in Riyadh, Saudi Arabia, from October 21 to October 24, following a high-profile change to the player roster. Learner Tien has been confirmed as the replacement for Jannik Sinner, who withdrew from the exhibition tournament due to injury, according to reports confirmed by multiple outlets including Tennis Actu and Puntodebreak.
Tournament Dates and Venue in Riyadh
The event is scheduled to take place over three days in late October: October 21, 22, and 24. Players will gather in the Saudi capital for the high-stakes exhibition. The schedule was finalized recently, with organizers confirming the lineup despite the abrupt late-season changes to the professional tour, as noted by Tennis Actu.
Learner Tien Replaces Jannik Sinner
The withdrawal of Jannik Sinner, who has announced he will not compete in any further tournaments for the remainder of the 2026 season, created an immediate vacancy in the Six Kings Slam draw. Organizers selected 20-year-old American Learner Tien to fill the spot. According to reports from Puntodebreak, the selection process was complicated by ATP regulations, which restrict players from participating in “special events” or exhibitions during weeks when they are officially entered into ATP tour tournaments. Tien, currently ranked 17th in the ATP standings, will make his debut at the event, facing a potential path that includes a quarterfinal match against Alex de Minaur.
Djokovic and Alcaraz Enter Six Kings Slam Semifinals
The Six Kings Slam utilizes a knockout format designed to feature top-tier talent. Novak Djokovic and Carlos Alcaraz have been granted direct entry into the semifinals due to their Grand Slam title counts. The remaining players compete in the quarterfinal round to determine who advances to face them. Regarding the financial stakes, reports indicate that each participant receives a significant base appearance fee. The ultimate winner of the tournament is set to earn a substantial prize, as reported by Tennis Actu.

Status of Alex de Minaur
The participant list remains subject to further adjustments. Alex de Minaur, who is slated to face Learner Tien in the opening round, was forced to retire during the final of the ATP 500 event in Beijing. As of the latest updates, his participation in the Six Kings Slam is considered uncertain, and organizers may need to secure an additional replacement should he be unable to compete, according to Tennis Actu and Puntodebreak.
Schedule of Matches
The tournament structure is organized as follows:
- Wednesday, October 21: Alexander Zverev vs. Taylor Fritz; Learner Tien vs. Alex de Minaur.
- Thursday, October 22: Carlos Alcaraz vs. the winner of Zverev/Fritz; Novak Djokovic vs. the winner of Tien/de Minaur.
