Alex de Minaur has maintained his perfect record at the Australian Open against lower-ranked opponents, outlasting big-hitting Serb Hamad Medjedovic to advance to the third round.
After being stunned by the world No.90 in the first set, de Minaur's superior fitness and class came to the fore as he prevailed 6-7 (7-5) 6-2 6-2 6-1 in three hours and four minutes on Rod Laver Arena.
