Day nine at Melbourne Park and that can only mean one thing: quarter-finals! Four of them to be exact, two in the womenâ€™s singles and two on the menâ€™s side.
First up, Naomi Osaka, the third seed, gets another chance to display her title credentials. But it wonâ€™t be plain sailing into the last four – evergreen dangerwoman Hsieh Su-wei lies in wait first up on Rod Laver.
To follow, itâ€™s menâ€™s 18th seed Grigor Dimitrov against Aslan Karatsev, before arguably the biggest matchup of this Open so far featuring Serena Williams and Simona Halep. And if that isnâ€™t enough, menâ€™s No 1 Novak Djokovic stares down sixth seed Alex Zverev in the final match of the day on centre.
