The action at the 2025 Six Kings Slam tournament is underway and attention will soon turn to the second round of the exhibition event.
Six of the world's top players entered the event and are competing in Riyadh, Saudi Arabia from Wednesday October 15 - Saturday October 18 for a lucrative winning prize total of $6m.
Reigning champion Jannik Sinner returned for the second edition of the event, as did fellow major champions Carlos Alcaraz and Novak Djokovic.
The trio were joined in the Saudi Arabian-capital by Alexander Zverev, Taylor Fritz and Stefanos Tsitsipas, with the latter being a late entry after Jack Draper withdrew from the event due to nursing a season-ending arm injury.
