Darren Cahill has been crowned Coach of the Year at the 2023 ATP Awards, along with his colleague Simone Vagnozzi. Together, they coach Jannik Sinner, who this year won four titles, including his first Masters 1000 title, was runner-up at the ATP Finals, and finished the year as the World No.4. Previously, Cahill has worked with the likes of Lleyton Hewitt, Andre Agassi and Simon Halep. But, as he explained, producing a Grand Slam champion takes a lot more than it might appear on the outside.
