Jannik Sinner: This curious situation raises more than a few doubts—fans are worried

The end of the global tennis season is turning into a complex game of interlocking pieces, numbers, and projections. With Jannik Sinner sidelined due to knee discomfort, the race for the top spot in the international rankings has suddenly reopened, and Alexander Zverev—who, like the Italian, had already qualified for the ATP Finals—is the one to benefit, but is now staging a strong comeback in both the ATP Rankings and the Race, thanks in part to Carlos Alcaraz’s elimination in the US Open quarterfinals at the hands of Ben Shelton.
Sinner sits atop the rankings with 11,500 points, but his lead is no longer unassailable. Zverev’s run to the quarterfinals of the US Open, combined with Alcaraz’s surprise elimination, has opened up a huge opportunity for the German: if he wins in New York, he would climb to 9,690 points, narrowing the gap with the Italian to 1,810 points. This is still a significant gap, but it doesn’t tell the whole story.
The real crux of the matter, in fact, is the points set to expire: Sinner must defend 3,550 points from Beijing, Shanghai, Vienna, Paris-Bercy, and the ATP Finals, while Zverev has just 1,080 points to defend. This factor, in the absence of immediate results, could open the door wide for Zverev to overtake Sinner in the ATP rankings. In the Race—which counts only results from 2026—Sinner leads with 7,950 points, but Zverev is hot on his heels with 7,050, a difference of just 900 points. If Zverev reaches the final, he would tie Sinner in points; if he wins the US Open, he would take the lead.
In the event of a tie, to determine who is truly first in the Race, the points accumulated in mandatory tournaments (Grand Slams and Masters 1000 events) would be considered: Sinner has 6,850, while reaching the final in New York would bring Zverev’s total to 7,060, putting him ahead. The overall picture thus reveals a simple truth: Sinner’s lead is no longer secure. The knee injury keeping him sidelined, the crucial points he must defend, and Zverev’s consistency are creating a scenario that worries Italian fans.
The Italian remains in control, but the pressure is real: the fall will be an obstacle course, and every result will carry immense weight. The good news is that Sinner has already qualified for the Finals, and once he’s recovered, he’ll be able to return to the court with the confidence of someone who has proven himself to be the best in the world. The bad news is that the margin between him and Zverev leaves no room for missteps.
