It's been 23 years since an Australian man has won a grand slam title. When Lleyton Hewitt won Wimbledon in 2002, his second major at 21 years of age, there looked to be plenty of Aussie success to come at grand slams.

Alex de Minaur, the world No. 8, and Nick Kyrgios, who is back after a two-year battle with knee and wrist injuries, are the headliners for their country at Melbourne Park. Kyrgios emceed the night session on John Cain Arena Monday, before De Minaur headlines Rod Laver Arena, the pantheon of Australian tennis Tuesday night.

After telling fans on the weekend his "legs are back", Alex de Minaur proved it on his way to the Australian Open quarterfinals.

Alex de Minaur busted through his Australian Open fourth-round ceiling with a brutal display against Alex Michelsen. Now, a date with world No. 1 Jannik Sinner looms.

Novak Djokovic's former strategist Craig O'Shannessy believes Alex de Minaur has his best chance yet to topple defending Australian Open champion Jannik Sinner.

Alex De Minaur kept the home flag flying at the Australian Open as he beat rising American Alex Michelsen 6-0 7-6(5) 6-3 to reach the quarter-finals for the first time on Monday. The 25-year-old has now reached the last eight at every Grand Slam and will face top seed and defending champion Jannik Sinner for a place in the semis.

Home favourite Alex De Minaur will face Jannik Sinner in the quarterfinals of the Australian Open after the world number eight beat world number 42 Alex Michelsen of the US 6-0 7-6 6-3 in the round of 16 Monday.
