World No. 1 Jannik Sinner ended his 2026 season on 6 October to treat knee inflammation, ruling himself out of the ATP Finals he won the past two years.
What Happened
World number one Jannik Sinner has ended his 2026 tennis season early because of a knee problem, ruling himself out of the ATP Finals in Turin, where he was the two-time defending champion. The Italian's management team announced on Tuesday, 6 October 2026, that he would undergo treatment for inflammation in his knee on the advice of his medical team. The decision came after he had already missed several events, including the US Open, the China Open in Beijing and the Shanghai Masters, which is under way this week. "At the moment, I also need to think about my long-term career," Sinner said in a video message.
Key Facts
- Sinner's team announced on 6 October 2026 that his season is over so that he can treat inflammation in his knee.
- He will miss the ATP Finals in Turin, scheduled for 15 to 22 November, where he had won the title the previous two years.
- He had earlier withdrawn from Cincinnati, the US Open, the China Open and the Shanghai Masters.
- The exact nature of the knee problem has not been formally confirmed by Sinner or his team.
- Sinner said he needed to think about his long-term career.
- Because he cannot defend ranking points from this part of last season, Alexander Zverev has a clearer path to overtake him in the rankings, according to reports.
- In Shanghai, Carlos Alcaraz opened his campaign on 10 October with a 6-3, 6-3 win over Juan Manuel Cerundolo.
Why It Matters
Sinner has been the dominant figure in men's tennis, and his absence changes the shape of the season's final weeks. The ATP Finals will go ahead without the man who won it in each of the last two years and who would have been the home favourite in Turin. Italian fans who bought tickets to see him have reportedly started reselling them.
The decision also says something about how top players now manage their bodies. Rather than rushing back for the last big events of the year, Sinner has chosen to stop, treat the problem properly and aim for the 2027 season.
For the rankings race, the effect is direct. Points earned at a tournament are defended a year later; a player who misses that event loses them. With Sinner out, rivals led by Alexander Zverev can close the gap at the top, and the race for the year-end number one position is now open in a way few expected earlier in the season.
| Event | Sinner's status |
|---|---|
| US Open | Withdrew |
| China Open, Beijing | Withdrew |
| Shanghai Masters | Withdrew |
| ATP Finals, Turin (15-22 November) | Will miss; season ended |
Impact
Short-term: The ATP Finals field opens up for another qualifier, and players chasing the year-end top ranking, including Zverev and Alcaraz, gain from Sinner's absence. Tournament organisers in Turin lose their biggest home draw.
Long-term: If treatment works, Sinner returns for the 2027 season with a fresh start, but the length of his absence and his eventual ranking will depend on how his knee responds.
Who is affected: Sinner and his team, rivals in the rankings race, ATP Finals organisers and ticket holders, and tennis fans around the world.
Key Takeaway
Jannik Sinner ended his 2026 season on 6 October to treat knee inflammation, missing the ATP Finals he won twice and opening the race for the year-end number one ranking.
