The highly anticipated Six Kings Slam is set to commence tomorrow in Riyadh, Saudi Arabia. Earlier today, Jannik Sinner and Stefanos Tsitsipas were the first to arrive, receiving a warm welcome from the organizers who presented them with bouquets.

Both players will compete against each other in the quarterfinals, while Alexander Zverev is scheduled to face Taylor Fritz in the other match. The victors of these encounters will meet Carlos Alcaraz and Novak Djokovic, respectively, in the semifinals, as they are the seeded players for this exhibition event.

On that note, let us review some of the key stories of the day:

1. Emma Raducanu sustains injury during Ningbo Open defeat

Emma Raducanu experienced a potential back injury as she was eliminated in the first round of the Ningbo Open. The British player has faced physical challenges since the start of her campaign in China, even undergoing a blood pressure check during the tournament.

In the second set of her match, Raducanu requested a medical timeout to address her pain. Ultimately, she lost to the Chinese wildcard, Zhu Lin, with a score of 3-6, 6-4, 6-1. Fans expressed their disappointment regarding her recent performances.

2. Nick Kyrgios asserts that ATP is ‘protecting’ Jannik Sinner

Nick Kyrgios has alleged that the ATP is shielding Jannik Sinner amid his doping controversy. The Australian has consistently criticized the Italian and recently reiterated this claim, suggesting that the ATP’s main officials are all compatriots of Sinner.

Nick Kyrgios has asserted that the ATP is providing protection to Jannik Sinner amid his doping controversy. The Australian has consistently criticized the Italian player and recently reiterated this assertion, indicating that the ATP’s key officials are all from Sinner’s home country.

In an appearance on the Unscripted Podcast hosted by Josh Mansour, Kyrgios remarked: “He’s the number one player in the world [at the time of his positive test], and there’s no doubt he’s an exceptional player who will be a significant figure in the sport for the next 10 to 15 years alongside Alcaraz. Therefore, it is evident that they are offering him some level of protection. The CEO and all the key figures within the ATP are Italian.”

Sinner made his return from a three-month suspension in May 2025, competing at the Italian Open.

Currently on a break from the court to recuperate from a knee injury, Casper Ruud has voiced his thoughts on Novak Djokovic’s remarks regarding the lack of unity among players, as they expressed their concerns about the demanding tennis schedule. Having previously discussed the rigorous nature of the calendar, Ruud responded to Djokovic’s comments in an interview with Bolavip, stating, “Certainly, Novak has a valid point… Yes, players can select their participation to some extent, as we are not employed by the ATP; we manage our own schedules. What I criticized and addressed during the French Open was the economic incentive to compete and the pressure to not miss any Masters 1000 events due to the bonuses and other factors.”
