The Six Kings Slam 2025 is off and running in Saudi Arabia.
The exhibition tournament was launched last year, when Jannik Sinner beat Carlos Alcaraz to be crowned the inaugural winner, and returns to Riyadh with another lucrative prize on offer.
On top of a reported $1.5 million participation fee, the winner of Saturday’s final is expected to take home $4.5 million – a bigger payout than any of the Grand Slams.
The eye-watering prize fund on offer has attracted the top five ranked players in the world as well as double Grand Slam finalist Stefanos Tsitsipas, who replaced the injured Jack Draper.
Wednesday’s quarter-finals were a little one-sided but more competitive clashes are expected on Thursday in some big semi-final clashes.
RadioTimes.com has rounded up everything you need to know about the star-studded cast of the Six Kings Slam 2025 tennis tournament.

Few embrace exhibition matches quite like World No. 1 Carlos Alcaraz, who certainly makes the most of the opportunity to thrill the crowds without the pressure of big tournaments.
Still just 22, the Spaniard already has six Grand Slams to his name and only needs to win the Australian Open to complete the set.
He has been given a bye straight to the semi-finals, where he will face Taylor Fritz – in a rerun of the recent Tokyo Open final, which Alcaraz won.

Jannik Sinner returns to defend his 2024 title on the back of an eventful year, which has seen him return from suspension to claim the Australian Open and Wimbledon titles.
The Italian’s growing rivalry with Alcaraz has become the big story in men’s tennis and fans will be hoping for another showdown in Saudi Arabia.
Sinner eased past Stefanos Tsitsipas in the quarter-finals and will meet Djokovic, who he beat in the 2024 final, in the last four.

One of three new additions for 2024, Alexander Zverev is a three-time Grand Slam finalist but has yet to win on the biggest stage.
Despite a disappointing run in recent months, the 6ft6in German is third in the world rankings and has vowed to “spoil the party” that Carlos Alcaraz and Jannik Sinner are currently enjoying at the top of men’s tennis.
That won’t happen in Riyadh, however, as Zverev was beaten by Taylor Fritz in the quarter-finals.

World No. 4 Taylor Fritz is another player making his Six Kings Slam debut in Saudi Arabia this week. His strong serving and aggressive style should be well-suited to exhibition play.
Fritz has made it no secret that the potential to walk away with $6 million was a major draw.

This man surely needs no introduction. The 24-time Grand Slam champion is the last of the ‘Big 4’ still standing and at 38, the World No. 5 has shown he can still mix it with the sport’s top players.
Novak Djokovic, who was beaten by Jannik Sinner in the last four last year, has a bye straight to the semi-finals, where he will face the Italian on Thursday.

Stefanos Tsitsipas is the only player outside the top 10 at Six Kings Slam 2025. He got the nod as Jack Draper’s replacement after the British No.1 called time on his season early due to an elbow injury.
The 27-year-old from Greece is down to 24th in the world rankings but has shown his quality in the past – with a career high ranking of No.3, an ATP Finals win in 2019 and final appearances at both the Australian Open and French Open.
Tsitsipas’ challenge did not last long, however, as he was handily beaten by Jannik Sinner in straight sets on Wednesday.
