World No. 1 Jannik Sinner cruised to a 6-3, 6-2, 6-1 quarterfinal triumph against home favourite Alex de Minaur to keep alive his hopes of lifting back-to-back titles at the hard-court major in Melbourne. Sinner, who entered the match having dropped just one set in nine previous ATP head-to-head meetings with De Minaur, motored to a one-hour, 48-minute victory with a clinical display of baseline hitting inside Rod Laver Arena as per ATP stats.
