Australian Open 2019
Venue: Melbourne Park
Dates: Jan 14-27
Wimbledon champion Angelique Kerber was knocked out of the Australian Open by world number 35 Danielle Collins in the biggest shock of the tournament.
The world number two was thrashed 6-0 6-2 in the fourth round in 56 minutes.
The German broke early in the second set but was immediately broken back and dropped serve a further two times.
"I was feeling good but you have sometimes days like this," said Kerber. "I was just trying [but] I couldn't find my rhythm."
Collins will play either American fifth seed Sloane Stephens or Russian Anastasia Pavlyuchenkova in the quarter-finals.
