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

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.
