Six Kings Slam live: Scores and updates as Jannik Sinner headlines first day of big-money Saudi exhibition on Netflix

World No 1 Carlos Alcaraz arrived in Riyadh last night ahead of the start of the Six Kings Slam. Alcaraz has not played since winning the Japan Open in Tokyo, where he defeated Taylor Fritz to win his eighth title of an astonishing season.

Alcaraz withdrew from the Shanghai Masters due to an ankle injury picked up in his opening match in Tokyo.

The Six Kings Slam line-up includes the world’s top-five, plus Stefanos Tsitsipas, who is currently ranked outside the top-20 in the world after a difficult season where he did not make it past the second-round of a grand slam.

But the Greek is a popular player, once tipped to be a future star, and a two-time grand slam finalist. He was called up to the replace the injured Jack Draper after he British No 1 called time on his season following the US Open.

Tsitsipas actually leads the head-to-head with Sinner 6-3, and won their last meeting in the semi-finals of the Monte Carlo Masters in 2024.

Jannik Sinner defeated Carlos Alcaraz in last year’s Six Kings Slam final, having also beaten Novak Djokovic in the semi-finals.

The Italian took home the $6m prize amid a dominant run of form towards the end of the season that included titles at the US Open and ATP Finals.

He returns as the defending champion having retired from his third-round match at the Shanghai Open after struggling physically.

The Wimbledon champion lost in the US Open final to Alcaraz – and could come face to face with the Spaniard in Riyadh for the first time since New York.

The Six Kings Slam will be shown live on Netflix. It is not a ‘pay-per-view’ event and is available to Netflix customers at no additional cost.
