World No. 1 Jannik Sinner left the tennis world gasping for air after the recently concluded 2025 Cincinnati Open. Just a week before his crucial US Open defence, Sinner’s retirement raised big question marks. Will the best player in the world be able to regain his fitness to compete for his third Grand Slam of 2025? Certainly, the timeline seems too short; however, stranger things have happened in tennis. In a slight relief for fans, Sinner’s coach Darren Cahill has given a positive update on the entire situation.

Yesterday I didn’t feel great and I’m really sorry to disappoint you. Thank you so much to everyone supporting me on-site and from home, your support means the world ❤️ Congrats to @carlosalcaraz and his team, you’re having an incredible season and I wish you all the best for… pic.twitter.com/hBxvHixEsH

Coach Darren Cahill Ends the Suspense On Jannik Sinner’s US Open Situation

Jannik Sinner raised many eyebrows after his abrupt retirement. Was he injured or just fatigued, fans wondered. However, Darren Cahill revealed to ESPN that it was neither; Sinner was just sick. “Jannik suffered from a virus that forced him to retire against Alcaraz on Monday,” Cahill said. Later, the coach revealed Sinner’s training plans ahead of the US Open.

“I spoke with him briefly last night. He was a bit better. He’ll take today off as well, that’s the plan, and I hope he’ll be able to take the court tomorrow and start hitting some balls,” Cahill said ahead of the US Open draw release on Thursday. “We are confident that he will be OK.” That will certainly spell hope for fans, as well as the Italian powerhouse himself. The 2025 campaign so far has brought about tremendous highs and equally destructive lows for the 24-year-old.

Sinner started the year with a bang, with his Australian Open win. But that was followed by a three-month suspension for returning positive tests for a banned substance. Then Sinner returned and came within one point of winning the French Open, but fell to Carlos Alcaraz. Later, he got his revenge by beating the 22-year-old at Wimbledon. Sinner started this year with two Grand Slams to Alcaraz’s four, but the gap has now narrowed to just one (Sinner four, Alcaraz five). Could Sinner equal Alcaraz and turn the heat on in this rivalry?

What Could the US Open Win Mean for Jannik Sinner?

Up until now, the rivalry between the top two players in the world has been one of mutual admiration. Though one could assume that Sinner’s “Hard work beats talent” speech may have been a veiled dig at Alcaraz after his Wimbledon win, they are both champion competitors. While the Cincinnati Open ending was anticlimactic, fans can expect to see more fireworks in the US Open. Sinner and Alcaraz headline a long list of title contenders – including Novak Djokovic and Alexander Zverev.

The tournament certainly holds great importance for Sinner. The four-time major champ has shown a successful knack for hard courts (although his US Open record of 17-5 is the worst of all Grand Slams). More importantly, a win here would mean Sinner equals Alcaraz in the Slam count and gains some momentum to surpass him next year. Alcaraz has never won an Australian Open; in fact, he’s won just 73% of his games there. Compare that to 89% wins in the French Open and Wimbledon, and suddenly US Open becomes even more important for both these stars. So who will prevail in this battle of champions? It will be known in just a few days.
