Title favourite Angelique Kerber withstood the unique challenge of Hsieh Su-Wei to move into the Australian Open quarter-finals. Her scalps in Melbourne had already included Wimbledon champion Garbine Muguruza and Agnieszka Radwanska, and for a long time it looked like Kerber might join them. The 2016 champion seemed close to losing it as Hsieh continued to spin her magic late in the second set, and the Kerber of last year would surely have crumbled. Keys, who hit 32 winners compared to just nine for her opponent, said: 'I'm feeling really good. I think I just played really solid and smart.'
