World number one Simona Halep fended off teenage wildcard Destanee Aiava to reach the Australian Open second round.
Halep saved two set points before beating the 17-year-old Australian 7-6 (7-5) 6-1 after medical timeouts for both players.
The Romanian, who plays Eugenie Bouchard next, had her ankle strapped in the second set, while Aiava left the court when leading 5-2 in the first.
Petra Kvitova was knocked out by Andrea Petkovic after an 88-minute final set.
The Czech 27th seed twice served for the match, at 6-5 and 8-7, while Petkovic could not convert three match points when serving for the match herself at 5-4.
However, a Kvitova double fault eventually handed victory to the 30-year-old German, 6-3 4-6 10-8.
Reigning Wimbledon champion Garbine Muguruza, seeded third, brushed aside her recent injury problems as she beat Jessika Ponchet 6-4 6-3 to book a second-round meeting with Su-Wei Hsieh of Taiwan.
Sixth seed Karolina Pliskova progressed with a 6-3 6-4 win over Paraguay's Veronica Cepede Royg on Rod Laver Arena.
Angelique Kerber, the 2016 champion, made it 10 singles wins in a row this year by seeing off fellow German Anna-Lena Friedsam 6-0 6-4. She will face Croatia's Donna Vekic in the next round.
French eighth seed Carolina Garcia beat Germany's Carina Witthoeft 7-5 6-3 and will face Czech Marketa Vondrousova next.
