Carlos Alcaraz takes on Jannik Sinner in the final of the 2025 Six Kings Slam on Saturday. It’s the second staging of the Saudi-backed tournament featuring six of the biggest names in men’s tennis. With a whopping £5 million up for grabs for the winner, it’s a nice Brucie bonus for the guys who have excelled as the season draws to a close.
It’ll come as no surprise to hear the pair have looked imperious leading up to the final. Sinner dispatched both Tsitsipas and Djokovic in straight sets, and Alcaraz was afforded the luxury of a bye into the semi-finals, where he waltzed past American Taylor Fritz in a little over an hour. It sets up the showdown that fans and sponsors would have wanted, as the pair meet after going head-to-head in three of the four major finals already in 2025.

*Odds correct as of 10:30 BST on 17/10/2025. Odds subject to change.
Bet 1: Carlos Alcaraz to Win – 10/11
Alcaraz has dominated Sinner this season, winning four of the five meetings and, more importantly, two of the three major finals (US Open and Roland Garros). The Spaniard will also benefit from having played one match fewer. While Sinner’s quarter-final with Tsitsipas was hardly gruelling, lasting just 76 minutes in a 6-2, 6-3 victory, it does all add up, especially at this point in busy seasons for the pair.
The bookies have this close to a coin flip, which is generous for Alcaraz. Odds of 10/11 for the Spaniard to continue his incredible form and dominating record over the Italian is the first value bet of the day.
Bet 2: Over 23.5 Total Games – 10/11
For the over 23.5 total games mark to land, we’re basically saying that this will go to a third-set decider. Given the quality of the two players, it feels like a no-brainer here and looks a great value bet at 10/11.
In the last five meetings in best-of-three sets, the over 23.5 mark has been passed four times (80%). These are two of the best in the world, so it could come down to an absolute marathon in Riyadh. The odds of 10/11 for a line with a historical success mark of 80% are too tempting to turn down.
Bet 3: 5+ Aces for Each Player – 4/6
These two are low-key exceptional servers. Their groundwork is so good that it often gets overlooked in their games. Sinner is slightly stronger this season, averaging 5.8 aces per match, and Alcaraz is a hair behind at 5.0. Elite numbers, by all accounts.
The Spaniard fired six aces in his semi-final with Fritz, and Sinner dominated the service games against Djokovic, with 10 aces across two sets. 5+ for each player is the final play in our Six Kings Slam bet builder.
