Iga Swiatek demolished Emma Raducanu on Saturday to sweep into the last 16 of the Australian Open as 38-year-old Frenchman Gael Monfils stunned fourth seed Taylor Fritz.

Later on day seven in Melbourne, Jannik Sinner will step up his title defence and young tyro Learner Tien is also in action.

In a one-sided battle of former US Open champions, Swiatek romped to a 6-1, 6-0 triumph in a statement victory as she pursues a first Melbourne crown.

Emma Navarro, the eighth seed from the United States, joined the Pole in the second week of the first Grand Slam of the year with a gritty three-set win over Ons Jabeur.

Sixth seed Elena Rybakina also advanced despite a back problem.

"I felt like the ball is listening to me," Swiatek said after rattling off 11 straight games in a brutal display against Britain's Raducanu on Rod Laver Arena.

The 23-year-old Swiatek is a five-time major winner but she has never gone beyond the semi-finals at Melbourne Park.

She faces world number 128 German Eva Lys next.
