Jannik Sinner battles fiercely in Vienna, aiming to preserve his hopes of finishing the year as world No. 1?

Surprisingly, after winning the Golden Ball in Saudi Arabia, Sinner went straight to Austria to take part in the Vienna Open. Other players are fighting hard to earn or guarantee their places in the year-end finals, but Sinner is the sole player competing this week who has already secured qualification.

At present, Sinner stands second on the ATP Turin live ranking list. Alcaraz dominates the battle for the ATP year-end No. 1 honor. Can Sinner mount a strong comeback in the final stretch of the season and snatch this title from his rival?

If Sinner harbors this ambition, he must begin his full sprint starting with this week’s Vienna Open, aiming to advance as far as possible.

Should Sinner perform well in this ATP 500-level Austrian tournament, he could add another 500 points to his PIF ATP Turin Finals qualifying tally this week. This would help narrow the points gap with Alcaraz.

ATP Turin Finals Qualification Points

This is crucial because Sinner cannot afford any mistakes. He currently trails Alcaraz by 2,540 points on the live rankings, which serve as a key indicator in the race for year-end No. 1.

After this week, both Alcaraz and Sinner plan to compete in the Paris Masters (offering up to 1,000 points) and the ATP Finals (offering up to 1,500 points). This means Sinner must fight for every point in the remaining tournaments of the season, while hoping Alcaraz cannot maintain his current excellent form—he holds a 2025 record of 67 wins and 7 losses—

If Sinner claims the Vienna title for the second time and then enters the Paris Masters, the points gap between him and the Spanish player will shrink to 2,040 points, giving him a chance to close the gap even further. Although Alcaraz will still have a clear advantage, the pressure on him will start to mount.

If Sinner fails to win a match in Vienna, he will still be 2,540 points behind entering the final ATP 1000-level event of the season—the Paris Masters. Even if he wins both Paris and Turin, his total points would reach only 11,000, while Alcaraz currently has 11,040. Moreover, in the week between Paris and Turin, Sinner has not registered for tournaments in Athens or Metz.

More importantly, Alcaraz will not be idle during the Paris and Turin events either. Therefore, with Alcaraz resting this week, Sinner’s performance in Vienna carries significant weight.

Both players are chasing their second ATP year-end No. 1 title in their careers: Alcaraz earned this honor in 2022, while Sinner first reached the top last year (2024).
