Even if Carlos Alcaraz wins the US Open 2026, he cannot reclaim the World No. 1 ranking. This is a clear conclusion from ATP points analysis, based on official tour data. Alcaraz, the 22-year-old Spaniard, has been sidelined since April 2026 due to a right wrist injury, causing him to miss seven major events, including Roland Garros, Wimbledon, Cincinnati Masters, and Queen's Club. As a result, his total points have dropped sharply from a peak to 7,160 points, ranking him No. 3 on the ATP leaderboard.

Meanwhile, current World No. 1 Jannik Sinner has 12,800 points. Even though Sinner is missing the US Open due to a right knee injury and will drop 1,300 points (the points he earned as runner-up in 2026), he still retains 11,500 points. World No. 2 Alexander Zverev has over 9,000 points and must defend less than 100 points at the US Open.

This means that, even in the best-case scenario – Alcaraz winning the US Open (2,000 points), Sinner losing in the first round (losing all 1,300 defending points), and Zverev losing in the first round – Alcaraz would still only have 7,160 points, while Sinner would have 11,500 and Zverev 9,000. Alcaraz cannot surpass Zverev to reach No. 2, let alone No. 1.

Detailed points structure analysis

Alcaraz's points mainly come from his 2026 US Open title (2,000 points), 2026 Indian Wells title (1,000 points), and 2026 Barcelona title (500 points). However, most of these points were accumulated in Q2 and Q3 of 2026 and are now in the defense window. If Alcaraz cannot participate in the corresponding tournaments in 2026, he will lose points.

Missing seven major events from April to August 2026 cost Alcaraz a total of 5,800 potential points: 2,000 from Roland Garros (2026 champion), 1,300 from Wimbledon (2026 champion), 1,000 from Cincinnati Masters (2026 champion), 500 from Queen's Club (2026 champion), along with points from Barcelona, Madrid, and Rome. This is the largest points loss in Alcaraz's career, reflecting the fragility of the ranking system when a player is sidelined long-term.

Impact of injury

Alcaraz's right wrist injury is the root cause. He has not played since April 2026, and returning to the US Open after more than four months of rest is a huge risk. Medical reports indicate his wrist is not fully healed, and the pressure to defend 2,000 points may push him to overexert. Even though Alcaraz posted 'Here we go' on social media, the reality is that his fitness and form are completely uncertain.

Tournament context

The US Open 2026 is the final Grand Slam of the year, played on hard courts at Flushing Meadows. With Sinner absent, Alcaraz becomes the top seed in one half of the draw, but opponents like Zverev, Novak Djokovic, and Daniil Medvedev remain major obstacles. Djokovic, though 38, is still dangerous on hard courts. Medvedev, a former US Open champion (2026), also has a strong record at the event.

Contrarian perspective

Some argue that Alcaraz's inability to reach No. 1 is due to Sinner's excellence, but the real reason is that Alcaraz cannot defend points due to injury. Even if Sinner lost all his current points (impossible, as they come from multiple events), Zverev remains a barrier. Zverev defends fewer than 100 points at the US Open, because he lost in the second round in 2026. This means Zverev can hold his No. 2 spot even if he loses early.

Risks and opportunities

The risk of reinjury is very high. The hard courts of the US Open place heavy stress on the wrist, and Alcaraz has had no match play to test his fitness since April. If he loses early, his points could drop to around 5,160, pushing him out of the top 5. This would create a paradox: a player of Alcaraz's immense talent could be ranked far below his actual ability.

However, there is also an opportunity. After the US Open, Alcaraz will have no points to defend until Indian Wells 2026 (because he missed the fall 2026 events due to injury). This means, if he fully recovers, he can climb the rankings quickly in 2026, with no defense pressure.

Conclusion

Data is never in a hurry. Those who rush are the ones who make mistakes. Carlos Alcaraz cannot reclaim World No. 1 at the US Open 2026, regardless of the outcome. This is a mathematical fact, not a subjective opinion. But the real story here is Alcaraz's return from injury, and whether he can maintain top form to win a second Grand Slam of the year. The US Open will be the ultimate test of the Spaniard's resilience and fitness.

Every shot is a hypothesis. xG is how we test it. In tennis, points are the ultimate measure. And at this moment, the measure shows that Alcaraz is still far from the summit. But like all great champions, he will come back stronger. The question is: when?
