Jannik Sinner is constantly working on improving his tennis with his coaches, Simone Vagnozzi and Darren Cahill. During a recent interview, the Italian player explained how he has improved his serve.

“I think we have improved a lot the serve. I still have days where I struggle a little bit more. I have days where I serve very well. But still, there is a lot of work to do. We tried to find the right motion, the right toss and the right tempo, no, to serve every ball in the same motion, no, and then changing the ball a little bit,” said Jannik.

“There is a lot of work to do still, but considering last year and this year, I feel like I have a different serve.”
