In a bad day for the women’s seeds, 2011 Brisbane International champion Petra Kvitova has fallen to Russian Anastasia Pavlyuchenkova in straight sets 6-4, 7-5.
The Czech sixth seed had beaten the young Russian on her way to the 2011 title but could not find a way through on Showcourt 1.
Pavlyuchenkova awaits the winner of fourth seed Angelique Kerber and Monica Puig in the quarterfinals.
