At the Laver Cup last month, Carlos Alcaraz complained that the tennis schedule is "going to kill us". But this week the Spaniard, who has only played two ATP events since the US Open, is playing the £11.5m Six Kings Slam in Saudi Arabia where Rafa Nadal and Novak Djokovic are also competing for the £4.6m first prize.

Rafael Nadal sets off on his pre-retirement farewell tour, starting against Carlos Alcaraz at the Six Kings Slam, an exhibition event in Saudi Arabia. Despite recent controversies, Nadal and Novak Djokovic advance to the semifinals.

Jannik Sinner has won 65 of his 71 ATP Tour-level matches this year, claiming seven trophies, including the Australian Open and US Open. Carlos Alcaraz, meanwhile, won the other two Grand Slam tournam

Rafael Nadal, in his first match since announcing he would be retiring after the Davis Cup next month, lost 6-3, 6-3 to Carlos Alcaraz at the Six Kings Slam on Thursday.
