Britain's Emma Raducanu suffered the joint heaviest defeat of her career as second seed Iga Swiatek demonstrated her superiority in a one-sided Australian Open third-round match.
Raducanu, 22, was thrashed 6-1 6-0 in a chastening afternoon on Rod Laver Arena in Melbourne.
The world number 61 lost serve five times in a defeat which took just one hour and 10 minutes.
It was the second time in her career that she lost with only a game to her name, following a 6-0 6-1 defeat by Kazakhstan's Elena Rybakina in Sydney three years ago.
Raducanu was unable to cope with Swiatek's top spin-heavy groundstrokes and athleticism, making a host of errors from the baseline - particularly on the backhand side - as the pressure told.
