World number one Jannik Sinner has paid tribute to departing coach Darren Cahill, confirming the end of their partnership after a season that "didn't end the way we wanted." The Italian star posted a message to the Australian coach on Friday, November 6, 2026, marking the conclusion of a collaboration that began in 2022.
Cahill, a former world number 22 and respected coach who previously guided Lleyton Hewitt and Simona Halep to Grand Slam titles, joined Sinner's team alongside Simone Vagnozzi. Under their guidance, Sinner captured his first two major titles at the 2024 Australian Open and 2024 US Open, ascending to the top of the ATP rankings.
The 23-year-old Sinner acknowledged the disappointment of how the season concluded, though specific details about the final tournaments were not disclosed in his message. The partnership's end comes despite Sinner's historic breakthrough year, which included eight tour-level titles and a 70-6 match record.
Cahill's departure leaves Vagnozzi as Sinner's primary coach heading into the 2027 season. The Italian federation and Sinner's management have not yet announced a replacement for the experienced Australian mentor.
