Five of the world’s top 10 men’s players will compete at a lucrative exhibition event in Saudi Arabia this week.
There is a reported $4.5m (£3.4m) in prize money on offer at the Six Kings Slam, with some players also likely to have been paid seven-figure sums to appear.
Reports say the winner could take home up to $6m (£4.5m).
For context, the US Open men’s singles champion won $5m (£3.8m), with £3.5m on offer at the Australian Open, £3m at Wimbledon and 2.5m euros (£2.2m) at the French Open.
The world’s top two players – Carlos Alcaraz and Jannik Sinner – are competing, alongside third-ranked Alexander Zverev, 24-time Grand Slam champion Novak Djokovic, world number four Taylor Fritz and two-time major finalist Stefanos Tsitsipas.
Britain’s Jack Draper was due to play but ended his season early because of an arm injury.
It is the second time the event has taken place, with Sinner beating rival Alcaraz in last year’s final.
The event is held over three days, over a three-set format, and will be streamed live on Netflix – having been shown on DAZN last year.
It begins at the quarter-final stage, with four-time Grand Slam champion Sinner playing Tsitsipas and Zverev facing Fritz. Djokovic and six-time major champion Alcaraz have been given byes through to the semi-finals.
As it is an exhibition, there are no ATP ranking points on offer. Results also do not count towards official head-to-head records., external
Matches will take place on Wednesday, Thursday and Saturday as, under ATP rules, players cannot compete on three consecutive days at exhibitions.
The event is held at The Venue, an 8,000-seater arena, as part of Saudi Arabia’s annual ‘Riyadh Season’ – which sees sporting tournaments and concerts held in the country’s capital.
