Jannik Sinner’s quest to reclaim the ATP World No. 1 ranking has gained fresh momentum following Carlos Alcaraz’s withdrawal from the Shanghai Masters due to a left ankle injury sustained during the Japan Open. With Alcaraz sidelined and Sinner lifting the China Open title in Beijing, the Italian star is now in prime position to challenge for the top spot in the ATP rankings before the end of October 2025.
Sinner, currently ranked World No. 2, defeated 19-year-old American Learner Tien 6-2, 6-2 in the China Open final, marking his third title of the season and his first since Wimbledon. The win not only avenged his 2024 final loss to Alcaraz at the same venue but also added crucial ranking points to his tally. With Alcaraz opting out of Shanghai, Sinner can mathematically reclaim the No. 1 ranking on October 27 if he wins the upcoming ATP 500 events in Shanghai and Vienna.
ATP Rankings Race – October 2025 Scenario
| Player Name | Current Rank | Points (Approx.) | Upcoming Events | Points to Defend | Opportunity to Gain |
|---|---|---|---|---|---|
| Carlos Alcaraz | 1 | 10,260 | Paris Masters, ATP Finals | 1,000 (Paris), 200 (Finals) | Limited due to injury |
| Jannik Sinner | 2 | 9,500 | Shanghai, Vienna, Paris, ATP Finals | 2,830 (Shanghai + Finals) | High if he wins Shanghai & Vienna |
Sinner’s path to the top is not without hurdles. He must win both Shanghai and Vienna to surpass Alcaraz’s points before the Paris Masters. Even then, the lead may be short-lived, as Alcaraz has fewer points to defend at the ATP Finals compared to Sinner’s 1,500 from his 2024 title win in Turin. If Sinner fails to replicate his Finals performance, Alcaraz could reclaim the No. 1 ranking by mid-November.
Jannik Sinner’s 2025 Season Performance

|---|---|---|---|
| Australian Open | Champion | 2,000 | Defeated Novak Djokovic in final |

| US Open | Runner-up | 1,200 | Lost to Alcaraz in final |

| Cincinnati Masters | Retired (Final) | 600 | Illness forced withdrawal |
Carlos Alcaraz, meanwhile, has had a stellar season, winning the US Open and Japan Open, and reaching finals in multiple ATP 1000 events. His decision to skip Shanghai is seen as a strategic move to recover and prepare for the Paris Masters and ATP Finals, where he can consolidate his lead.

The rivalry between Sinner and Alcaraz has defined the 2025 ATP season, with the two sharing all four Grand Slam finals. Their head-to-head record remains evenly matched, and both players have shown maturity beyond their years in handling pressure and expectations.
Sinner’s coach Darren Cahill believes the Italian is ready to embrace the challenge. “Jannik has grown tremendously this season. He’s focused, disciplined, and hungry. The No. 1 ranking is within reach, but we’re taking it one match at a time,” he said.
Social media platforms have been buzzing with excitement over the ranking race, with hashtags like #SinnerVsAlcaraz, #RaceToNo1, and #ATP2025 trending across tennis forums and fan pages.

Tennis analysts suggest that even if Sinner briefly reclaims the No. 1 ranking, the year-end crown will likely depend on ATP Finals performance. With 1,500 points at stake, the Turin showdown could be the decider in one of the most competitive seasons in recent memory.
In conclusion, Jannik Sinner has a realistic shot at reclaiming the World No. 1 ranking from Carlos Alcaraz, especially with the Spaniard sidelined from Shanghai. However, sustaining that position will require consistent victories and a repeat of his ATP Finals triumph. As the indoor season unfolds, fans can expect a thrilling finish to the 2025 ATP calendar.
