Naomi Osaka used her experience of previous struggles to swiftly dispatch Chinese Taipei’s Hsieh Su-wei and seal her place in the Australian Open semi-finals.

Osaka’s 6-2 6-2 win over her unorthodox opponent provided a stark contrast to her victory over same player en route to the title in 2019, when she had been forced to rally from a set and a break behind.
