Defending champion Angelique Kerber survived an upset from fellow German Carina Witthoeft to advance to the Australian Open third round.
The women’s No 1 seed defeated Carina Witthoeft 6-2 6-7 6-2 but another second set collapse similar to her first round slump against Lesia Tsurenko will have been a concern.
The German said: “I’m trying to play more aggressive but today I was doing a few more mistakes. I was not finding my rhythm from the first ball.
“It was not so easy. The conditions were a little bit difficult today and I was a bit too defensive. At the end I won and this is all that counts for me.”
Angelique Kerber, who was 29 on Wednesday, will face Czech Kristyna Pliskova in the next round.
Unseeded Witthoeft had previously lost twice to her compatriot Kerber at Wimbledon, including an embarrassing ‘double bagel’ in 2015.
