De Minaur aiming to smash through barrier after reaching last 16

MELBOURNE :Surviving home hope Alex De Minaur has his eyes on breaking through his fourth-round barrier for the first time at the Australian Open after reaching last 16 without losing set.

The 10th seed crushed Italian qualifier Flavio Cobolli 6-3 6-3 6-1 on Friday to continue an impressive start to the season which included a win over Novak Djokovic at the United Cup.

"I'm hoping I can break that barrier and go one further."

None of De Minaur's matches so far have gone beyond two hours, leaving him fresh for his clash with tenacious Russian fifth seed Andrey Rublev after he beat American Sebastian Korda to take his place in the fourth round.

"Physically I'm feeling great. Now it's just about giving all my energy for what's to come."

The hard work starts now for De Minaur if he is to finally make his mark at a Grand Slam after a rather
