Jannik Sinner may surpass Alcaraz to reclaim the world No. 1 spot right after the 2025 Paris Masters.

However, even if Sinner temporarily overtakes his rival, that position might only last briefly. At the ATP Finals in Turin in November, Sinner must defend 1500 points as the reigning champion, while Alcaraz only needs to defend 200 points. This means the Spaniard could reclaim the top spot once the Turin event concludes.

Nevertheless, Sinner remains highly motivated as he seeks to finish the 2025 season by capturing his first Masters 1000 title of the year. The competition between these two promising young players has become a major highlight in the tennis world.

They have faced each other in three of the four Grand Slam finals this season: Roland-Garros, Wimbledon, and the US Open. Alcaraz won at the French Open and US Open, while Sinner made history by winning his first Grand Slam title at Wimbledon.

Although in great form, Sinner has yet to win a Masters 1000 title this year, while Alcaraz has secured three championships in Monte-Carlo, Rome, and Cincinnati.

However, the Italian’s current form is impressive. After his tense victory over Zverev in Vienna, Sinner said, "It feels fantastic. The start of the final was tough; I lost my serve early and missed some chances in the first set. He served very well, but I stayed mentally strong and played my best tennis when needed. The third set was like a roller coaster, but I felt the ball well and seized opportunities to attack. Winning another title is very special."

Sinner also emphasized that resilience was key to his win: "The most important thing is never to give up. I try to observe the situation, make timely decisions, and conserve energy during my service games. Both of us played very well today, and I am satisfied with my performance."

The race for the world No. 1 ranking between Jannik Sinner and Carlos Alcaraz is expected to become even more thrilling at the Paris Masters — where both are eager to end the season with a standout victory.
