On this occasion, Jannik Sinner did so against none other than his familiar rival, Carlos Alcaraz (world No. 1), in the highly anticipated final of the Six Kings Slam 2025. The Italian star claimed a commanding victory, sealing the title 6–2, 6–4, in a masterclass that reaffirmed his place among the sport’s elite.
For Sinner, a former world No. 1 himself, this triumph marks not only a successful defense of the crown he earned in 2024—also against Alcaraz—but a historic milestone in tennis.
