Sinner's Withdrawal and Injury Battle
Jannik Sinner, the 25-year-old Italian who holds the world No. 1 ranking, has pulled out of the Rolex Shanghai Masters, a Masters 1000 event scheduled for October 7-18. The withdrawal, announced on his Instagram story on Saturday, stems from a right knee injury that has troubled him since his Wimbledon triumph in July. Sinner has not competed since that victory, missing the North American hardcourt season, including the US Open, and the ATP 500 tournament in Beijing. In his announcement, he conveyed his disappointment and thanked fans for their support, indicating he looks forward to returning next year.[S1][S2]
The injury has been identified by Italian journalist Gabriele Parpiglia as iliotibial band (ITB) syndrome, a condition where the band slides over the knee, causing inflammation between the fascia and bone. Despite optimism from Italian media about a possible return in Shanghai, Sinner's team has not provided a timeline for his comeback. The knee has not healed as quickly as hoped, leaving the entire Asian swing without the top seed. Sinner had won the Shanghai title in 2024, defeating Novak Djokovic in the final, and his absence is a significant blow to the tournament.[S2]
Zverev's Opportunity to Seize No. 1
Sinner's withdrawal creates a major opening for Alexander Zverev, the German who has emerged as his closest rival. Zverev, the French Open and US Open champion this year, currently sits at 9,670 points, trailing Sinner's 11,000. However, Sinner is defending only 50 points in Shanghai, meaning Zverev could ascend to world No. 1 for the first time if he wins both the China Open in Beijing and the Shanghai Masters. The Shanghai tournament features a strong field led by four-time champion Novak Djokovic, along with Carlos Alcaraz, Daniil Medvedev, Ben Shelton, Felix Auger-Aliassime, and defending champion Valentin Vacherot.[S1][S2]
The ranking implications add a dramatic twist to the ATP season's conclusion. Sinner remains confirmed for upcoming events, including the Vienna Open starting October 24 and the Paris Masters, with four tournaments left on his schedule. His record at these events is impressive: he is a past champion in Vienna (2023 and 2025), Paris (2025), the ATP Finals (2024 and 2025), and the Davis Cup Finals in Bologna, where he helped Italy to titles in 2023 and 2024. Yet, with his knee injury lingering, the immediate focus shifts to Zverev's pursuit of the top spot, which could be decided in the coming weeks.[S2]
