Sinner steps up a gear to reach the third round

Jannik Sinner continues her journey in New York.

Moving up another notch, the world number 1 never gave Alex Michelsen a moment's peace, winning in just over an hour and a half (6-4, 6-0, 6-2).

After a very average first act, in which he twice conceded his first set, the Transalpine totally dominated the match, losing only 2 of the last 16 games.

After a reassuring match, Sinner will challenge O'Connell for a place in the second week.
