The 23-year-old Canadian, who had not won back-to-back matches since Indian Wells, rallied from a break down in a tight first set before racing through the second by winning the final six games.
“I need results like this,” said Auger-Aliassime, after backing up his win over Aleksander Vukic in the first round. “I believe in my game and I believe in myself that I have what it takes to win at this level. I have done it before but it is about doing it and having a lot of belief and a positive mind. I am happy that my level is translating to the match court after a couple of months.”
Zhang fired 10 aces and broke serve three times to avenge his defeat to the 11th-ranked Hurkacz in Shanghai last week.
Nao Hibino of Japan followed her victory over top-seeded Beatriz Haddad-Maia in the first round with a 6-3, 7-5 win over Kimberly Birrell. The 93rd-ranked Hibino will play Diana Shnaider in Friday’s quarterfinals after the Russian advanced when Vera Zvonareva retired due to illness when trailing 6-3, 0-1.
