Jannik Sinner became world number one after Novak Djokovic’s worst fears were realised when he had to withdraw from his French Open quarter-final against Casper Ruud with a knee injury.
Sinner only found out the news after his three-set win over Grigor Dimitrov which took him into the semi-finals, where he will face Carlos Alcaraz following the Spaniard’s victory over Stefanos Tsitsipas.
