For the second year in a row, Jannik Sinner took home a record $6 million prize money, as he successfully defended his Six Kings Slam crown by beating top-ranked Carlos Alcaraz 6-2, 6-4 in Saturday’s final of the exhibition event in Riyadh, Saudi Arabia.
Sinner, who also beat Alcaraz in the 2024 final, earned the biggest payout in tennis from the four-day, short-format event where six of the world’s top players – including Novak Djokovic – competed.
The winner of the tournament was assured of $4.5 million prize money while each player received $1.5 million in appearance fee.
Sinner’s improved serve proved to be the gamechanger in the final, as he won 80% of his service points and did not allow Alcaraz a single break point, sealing victory in an hour and 13 minutes.
“I wish I could play like this everywhere,” Sinner said in his on-court interview.
“This season we played many, many times and I also lost many times to Carlos. It is a huge pleasure and honor to share the court with him.”
Sinner and Alcaraz faced off in all four Grand Slam finals this season, as Sinner won the Australian Open and Wimbledon titles, while Alcaraz triumphed at the French Open and the U.S. Open.
There has been a growing rivalry on-court between the world’s top two players, but Sinner said they share a “very special” friendship outside of tennis.
“… You want to get better as a player and you need rivalries in the sport. So it’s nice to have a great rivalry and more importantly a great friendship off the court,” Sinner, 24, added.
“We have a very special friendship and it’s very nice.”
Alcaraz Praises ‘Great’ Sinner
Alcaraz complimented the changes Sinner made to his game, saying the Italian did not let him “get a good rhythm”.
“He was improving a lot, the serve, and I could feel it. No break points today, which for me is something weird, “Alcaraz, 22, said.
“I’m used to at least one break point in the match. But when he’s serving really good it’s really difficult. I couldn’t find a solution today, so I think he deserved it.”
Sinner, who defeated Djokovic in straight sets in the semi-finals, said before the final that he had been working on his serve in the past month, especially after losing the U.S. Open final to Alcaraz.
While winning the Six Kings Slam championship could give Sinner a confidence boost for the final stretch of the 2025 season, the result will not count towards any ATP records or rankings, as it is an exhibition event.
