Alex de Minaur ticked off yet another milestone in his illustrious career Monday, taking down American Alex Michelsen to qualify for the quarter-finals of the Australian Open for the very first time.

Pressure is said to be a privilege, and this has never been lost on Alex de Minaur, but the world number eight has become accustomed to bearing the weight of expectation.

Alex de Minaur overcame a one-set deficit and his own serving yips Saturday afternoon to defeat 31st-seed Francisco Cerundolo in a marathon third-round Australian Open match.

Alex de Minaur will be aiming to make the Australian Open quarter-finals for the first time when he takes on American talent Alex Michelsen at Rod Laver Arena on Monday night. The Australian eighth seed has reached the fourth round on four occasions but has never made it through to the last eight at Melbourne Park.

He’s shown what an incredible tennis player he is, and he’s ranked (in) top 10 in the world, and has been there for a whole year, which is not an easy thing to do. I’ve learnt so many different ways of becoming a better tennis player.
