Defending champion Jannik Sinner has moved into the quarterfinals at the Australian Open after beating Holger Rune during a match slowed down by medical timeouts for each player and a delay because the net got knocked loose.

World No.1 and defending champion Jannik Sinner, Iga Swiatek, Elina Svitolina, Elena Rybakina and other big players will be in action on Day 9 of the hard court major at the Melbourne Park.

The World No. 1, despite feeling unwell in sweltering conditions, kept up his title defense with a four-set triumph.
