Some of the other big hitters coasted through to the third round
Women's sixth seed Petra Kvitova was the biggest name to fall on day three of the Australian Open.
The two-time Wimbledon champion was beaten in straight sets by Australian Daria Gavrilova losing 6-4, 6-4.
However, there were no problems for Serena Williams, Maria Sharapova, Agnieszka Radwanska, Novak Djokovic, Roger Federer and Jo-Wilfied Tsonga, who are all safely through to the third round.
Meanwhile, Venus Williams was fined for skipping her post-match press conference after her shock first round loss to Britain's Johanna Konta yesterday.
The US tennis star has to pay a record $5,000, which is the most that a women's player has had to pay for that transgression.
