Emma Raducanu has been inflicted with the joint-heaviest defeat of her career as second seed Iga Swiatek showcased her superiority in a one-directional Australian Open third-round match.
Britain's Raducanu was bashed 6-1 6-0 in a hot afternoon on Rod Laver Arena.
The world number 61 lost serve five times as Swiatek used barely 70 minutes to secure victory.
It is the second time Raducanu has won just one game in a match, having lost 6-0 6-1 to Kazakhstan's Elena Rybakina in Sydney three years ago.
"She played very well, but I also think I didn't play very well. It's just not a great combination," Raducanu, 22, said.
Five-time Grand Slam champion Swiatek has never gone past the Melbourne semi-finals but her level against Raducanu sent another warning to her title rivals.
The 23-year-old Pole has not dropped a set or even a service game in her first three rounds in Melbourne.
"If a top player is playing perfect, it's already going to be a difficult match," Raducanu added.
