American teenager Coco Gauff recovered from a set down to set up a meeting with defending champion Naomi Osaka in the Australian Open last 32.
World number one Ashleigh Barty also reached the third round on Wednesday.
Japanese third seed Osaka put a "childish" outburst behind her to beat Saisai Zheng 6-2 6-4 before 15-year-old Gauff saw off Romania's Sorana Cirstea.
The world number 67 was 3-0 down in the deciding set but fought back to win 4-6 6-3 7-5 in two hours and six minutes.
