Competing at the ATP 250 event, the second-seeded Canadian recovered from a slow start to overcome Australian Jason Kubler, advancing 4-6, 6-1, 6-4 after two hours and 16 minutes.
Auger-Aliassime struggled on return in the first set, winning just 20 per cent (5/25) of his points behind Kubler’s first and second serve. However, he found his range as the match went on, hitting with greater depth and aggression on return in the second and third sets to break the 29-year-old three times.
The 22-year-old, who is up one spot to No. 8 in the Pepperstone ATP Live Rankings, has levelled his ATP Head2Head series against Kubler at 1-1.
Auger-Aliasime will face seventh seed Alejandro Davidovich Fokina or Soonwoo Kwon in his second tour-level quarter-final of the season. The four-time tour-level titlist reached the last eight in Rotterdam last week.
Having defeated then-World No. 9 Auger-Aliassime in Newport last year, Kubler was aiming to earn his second victory against the Canadian and the second Top 10 win of his career. The Australian is up three places to No. 71 in the Pepperstone ATP Live Rankings after beating Aslan Karatsev in the first round in Doha.
