Sinner wastes no time and joins the second week
Jannik Sinner seems to be immune to the wave of surprises sweeping through the New York favorites.
While Djokovic and Alcaraz have already been eliminated, and Ruud and Zverev have found it extremely difficult to get out of tricky matches, the world number 1 continues to string together solid, quiet successes.
With the exception of the first set of his first round, the Transalpine dominates his matches, suffocating his opponents with his precise, powerful strokes.
Thus, against Christopher O'Connell on Saturday, he never really wavered, perfectly dictating the tempo of the match and dominating all aspects of the game (47 winners, 22 unforced errors, 15 aces, 0 break points conceded) to win in less than 2 hours (6-1, 6-4, 6-2).
For a place in the quarter-finals, he will face the winner of the duel between Tommy Paul and one of this tournament's surprise guests, Gabriel Diallo.
