SYDNEY (Reuters) - World number seven Angelique Kerber has pulled out of the Sydney International with a gastro-intestinal illness, the latest in a string of withdrawals to hit the Australian Open warm-up.
Organizers announced the German’s withdrawal on the tournament’s Twitter account.
The 27-year-old won her opening match of the tournament on Monday, defeating Ukraine’s Elona Svitolina 4-6 6-0 6-3, after coming off a runner-up finish at the Brisbane International on Saturday.
Defending champion Petra Kvitova also pulled out of the tournament with a stomach bug and world number five Agnieszka Radwanska withdrew with a left leg injury.
World number two Simona Halep, who opens her tournament against Frenchwoman Caroline Garcia later on Tuesday, is the top seed at the event.
