On July 23, Sinner's team confirmed that Umberto Ferrara, who had initially been let go in the wake of the positive Clostebol case, had been rehired as a fitness coach.

After Emma Navarro's withdrawal, Jannik Sinner will make his US Open mixed doubles debut alongside one of the most decorated doubles player of the last decade. World no. 1 will join forces with Katerina Siniakova.

Jannik Sinner has been put on notice about a rising star on the ATP Tour, who could soon make his mark at the top of the sport. Many tennis fans would welcome this change, as the duopoly that has formed at the top of the men’s game is starting to wear a little thin.
