Camila Giorgi produced an inspired performance to end a struggling Caroline Wozniacki’s dominance of the Tokyo Open and will face Victoria Azarenka in the quarter-finals.

Wozniacki won the tournament in each of the last two years, but the world number two’s poor form continued as Giorgi marched into the last eight with a 6-2, 2-6, 6-4 victory.

The unseeded Giorgi had not beaten the Australian Open champion for four years, but the sprightly Italian outplayed the top seed with an outstanding display on Thursday.
