Italian tennis star Jannik Sinner has announced the end of his coaching partnership with Darren Cahill after more than four years together.
The split comes as Sinner continues his campaign at the 2025 Australian Open, where he reached the semifinals with a victory over Ben Shelton of the United States on January 24 at Melbourne Park.
Cahill, a former professional player and respected coach, joined Sinner's team in 2021 and helped guide the Italian to multiple titles including his first Grand Slam championship at the 2024 Australian Open.
Neither party has disclosed the specific reasons for the separation, which marks the end of one of the most successful player-coach relationships in recent men's tennis.
