Third-seeded Alexander Zverev overcame a sluggish start to defeat Canada’s Gabriel Diallo 6-7(1), 6-1, 6-4, 6-2 on Sunday night, securing his place in the second round of the Australian Open for the 10th time.
After dropping a one-sided opening-set tiebreak, the German world number three completely took over the contest, finding the elite level that saw him reach the final in Melbourne last year. Zverev’s resurgence was built on an impenetrable service game; following the first set, he was nearly untouchable on his own delivery, winning 88% of his service points across the second, third, and fourth sets – losing just 7 points in total during that span. This stood in stark contrast to a shaky opening frame where he lost 16 points on serve (16 out of 39).
This dominant performance allowed him to dismantle Diallo’s resistance, breaking the Canadian six times while surrendering only one break point of his own throughout the nearly three-hour encounter.
Having efficiently navigated his opening test, he now awaits the winner of Monday’s match between Australian favorite Alexei Popyrin and France’s Alexandre Muller.
