Defending champ Jannik Sinner drops set for first time since October, but rallies for win; American Danielle Collins plays villain while advancing.

Defending champion Jannik Sinner raced to victory at the Australian Open to sweep into the last 16 as Iga Swiatek demolished Emma Raducanu. Also into the second week is 38-year-old Gael Monfils after he stunned fourth seed Taylor Fritz – with the veteran’s wife Elina Svitolina also enjoying a shock win immediately afterward on the same court.

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.
