NEW DELHI: Jannik Sinner, the defending champion, admitted that a lengthy break when he unintentionally broke the net was "big, big luck" after overcoming dizzy spells in the sweltering heat on Monday to advance to the Australian Open quarterfinals.
On Rod Laver Arena, the world number one lost a set once more before defeating Danish 13th seed Holger Rune 6-3, 3-6, 6-3, 6-2, with both players requiring medical care.
