Jannik Sinner has continued his stunning season with another trophy, having triumphed at the Six Kings Slam.
Sinner beat Alcaraz in the final of the Six Kings Slam, which represented a repeat scenario of last year’s final in Riyadh.
This time around, the Italian defeated the Spaniard 6-2, 6-4 to claim the title and the $6million in prize money.
The victory does, however, have no impact on their official head-to-head or world rankings given it was not affiliated with the ATP Tour.
Earlier in the day, Taylor Fritz defeated Novak Djokovic in the third place playoff, in which the Serbian retired after losing the first set 6-7(4-7).
Mark Petchey claims Jannik Sinner has a ‘nightmare’ shot for everyone on the ATP Tour
Sinner plays next in Vienna, where Emma Raducanu’s former coach Mark Petchey believes he will continue to be a real threat because of one particular shot.
At 4-3, 15-0 in the second set, he said on the coverage on Netflix: “That serve is a nightmare for everybody going forward. How do you get back to neutral? It’s going short and wide. You are outside the doubles line.”

Concurring, Feliciano Lopez replied: “There is no way to neutralise that serve and if you are able to put the ball in play you are so far off the court.”
The serve in discussion went out wide to Alcaraz’s backhand, with the point finished off with a drive volley.
Where does Jannik Sinner rank among the ATP service leaders in 2025?
While the statistics don’t reveal everything, they certainly help detail just how deadly Sinner is with his serving.
Only Giovanni Mpetshi Perricard and Taylor Fritz boast a better serve rating than the Italian on the ATP Tour in 2025.
| Rank | Player | Serve rating | % 1st serve | % 1st serve points won | % 2nd serve points won | % service games won | Avg. aces/match | Avg. double faults/match |
| 1 | Giovanni Mpetshi Perricard | 298.7 | 65.4% | 78.9% | 54.4% | 89.6% | 14.6 | 4.2 |
| 2 | Taylor Fritz | 296.9 | 64.1% | 79.8% | 54.2% | 89.3% | 11.3 | 1.8 |
| 3 | Jannik Sinner | 295.1 | 60.5% | 78.7% | 59.4% | 91.5% | 6.4 | 1.4 |
| 4 | Alexander Zverev | 294.8 | 71.5% | 74.7% | 54.9% | 88.0% | 7.7 | 2.0 |
| 5 | Novak Djokovic | 292.9 | 66.6% | 76.5% | 55.2% | 88.5% | 8.2 | 2.1 |
But Sinner’s name rises to the top of the pile when it comes to % service games won, while he’s also first for % 2nd serve points won.
The four-time Grand Slam champion is clearly enjoying his tennis in that specific area and indeed others right now, and is undoubtedly one of the two players to beat on the ATP Tour alongside Alcaraz.
