Jannik Sinner does not betray. On the New York hard court where Carlos Alcaraz and Novak Djokovic have already fallen, the 23-year-old from South Tyrol continues on his way, in a crescendo of condition and play. Round of 16 reached, without too many worries: the Australian Christopher O’Connell, fresh from the success against Bellucci, is unable to oppose the blows of the blue, who closes it in less than two hours with a score of 6-1 6-4 6- 2.
