"Another curve ball" - Paul McNamee offers his take on Jannik Sinner's coach Darren Cahill's US Open absence after Umberto Ferrara’s rehiring

Sports Administrator and former player Paul McNamee shared his thoughts on Jannik Sinner's coach, Darren Cahill, who will not be present with the Italian during his battle in the 2025 US Open. The Australian former tennis star further reflected on Cahill's absence, as he has taken a short break from coaching.

Sinner has become the World No.1 singles player under the tutelage of Darren Cahill and Simone Vagnozzi, who have been coaching him since 2022. The 23-year-old, right-handed star has won 20 ATP Tour singles titles, including four major titles. He won the US Open in 2024 by defeating Taylor Fritz in the final.

The Italian recently rehired his former fitness coach, Umberto Ferrara, who was involved in the 2024 doping case along with his physiotherapist, Giacomo Naldi. Considering the absence of Cahill from Sinner's 2025 US Open tournament journey, the Australian former World No. 1 in the doubles category, Paul McNamee, added his thoughts on the matter via X, writing:

"Darren missing the US Open is another curve ball… knowing Darren, he wouldn’t do it without good reason"

Jannik Sinner recently won the Wimbledon men's singles by defeating Carlos Alcaraz in the final for his fourth Grand Slam title.

Jannik Sinner's co-coach, Simone Vagnozzi, reflected on Cahill's importance and future with the team, as per the ATP Tour's official site. He shed light regarding his growth with Cahill and their mutual goal of making Sinner the top-seeded player. He told the ATP Tour:

“I have to say that I’m so lucky to have met someone like Darren, both professionally and personally. We connected immediately, and that undoubtedly helped us in our journey. It’s never easy to find that chemistry, but we’ve always prioritised Jannik’s interests."

He continued:

“In practice, we have different roles; I’m responsible for the more technical and tactical side of things, and he is more in charge of the mental and emotional aspects. Of course, we share everything, and the most important thing is that the player always hears one united voice. Honestly, nothing’s certain at the moment. But we’ll all be happy if Darren stays.”

Jannik Sinner will not grace the court of the 2025 Canadian Open due to health reasons.
