The tennis world got a jolt on Friday, August 7, as World No. 1 Jannik Sinner officially withdrew from the Cincinnati Open. The defending champion and top seed is battling a recurrence of the hip issue that derailed his spring - and he's putting his US Open title hopes first. Here's everything you need to know about the massive withdrawal, what it means for the ATP rankings, and when we might see Sinner back on the court.
This isn't a panic move - it's a calculated one. Sinner's 2026 season has been nothing short of spectacular: a 42-4 record and five titles, including the Australian Open and Wimbledon. But that glittering résumé comes with a cost. His body is screaming for a timeout. The Italian superstar hasn't played a competitive match since his Wimbledon quarterfinal loss on July 8, and now we know why. The hip that betrayed him in the spring is acting up again, and he's refusing to risk his biggest prize of the summer.
The Injury: A Flare-Up in the Hip, Not a Tear
This isn't a new problem. Sinner is dealing with a flare-up of the iliopsoas tendinopathy in his right hip - the same injury that forced him to miss the French Open earlier this season. An MRI on August 6 in Monaco showed mild inflammation, but crucially, no new structural tear. His medical team has ordered 10 days of complete rest.
That timeline is crucial. With the US Open starting on August 24, the rest period means his participation in New York is "probable but not guaranteed." Sinner will be "day-to-day" when practice sessions begin on August 18. The good news for fans? This is not a severe setback - but it's a warning sign that the tendinopathy is still lingering.
📊 42-4 win-loss record in 2026 - The World No. 1 has been nearly untouchable this season, with five titles including two Grand Slams.
The Priority is Clear: Flushing Meadows
In his statement posted on Instagram, Sinner made his intentions obvious. "After consulting with my doctors in Monaco, we decided it is best to skip Cincinnati to guarantee full recovery. The US Open is the priority." That's a clear message: the 22-year-old is protecting his shot at a second Grand Slam title of the year. It's a smart long-term play, but it leaves Cincinnati without its biggest draw.
Ranking Fallout: Sinner Stays No. 1, But Alcaraz Closes In
Even without playing a single match in Ohio, Sinner will retain his World No. 1 ranking after the tournament wraps up. However, his lead at the top is about to get a lot tighter. Before the withdrawal, Sinner held a 1,850-point buffer over No. 2 Carlos Alcaraz. After the August 17 ATP rankings update, that lead will shrink to just 1,240 points.
Table: ATP Top 3 Rankings Projection (Post-Cincinnati)
| Rank | Player | Points (Projected) | Change |
|---|---|---|---|
| 1 | Jannik Sinner | ~12,540 | -610 |
| 2 | Carlos Alcaraz | ~11,300 | +0 |
| 3 | Novak Djokovic | ~8,890 | +0 |
That puts Alcaraz in a prime position to pounce. If Sinner struggles in New York - or worse, pulls out before the US Open - the race for year-end No. 1 becomes incredibly compelling. For now, though, Sinner's dominance keeps him comfortably on top.
What Happens Now in Cincinnati? The Draw Shake-Up
Sinner's exit sends ripple effects through the Cincinnati draw. As the No. 1 seed and defending champion, his removal is a major blow to the tournament's star power. Here's the logistical impact:
