Coach who helped Sinner to the top set to depart

The coach who helped guide Jannik Sinner to five Grand Slam titles and the world number one spot is to leave the player's camp at the end of the year.

Australian Darren Cahill, 61, joined the Italian's team in June 2022 when Sinner was just outside the world's top 10 and had never progressed beyond the quarter-finals of a Grand Slam tournament.

But, together with Italian coach Simone Vagnozzi, Cahill has helped Sinner to go on to win five Slams and occupy the world number one spot for 95 weeks.

Injury has meant the 25-year-old has not played since winning Wimbledon for the second year in a row in July, which led to Alexander Zverev recently overtaking him at the top of the rankings.
