Britain's Katie Boulter beat Anna Kalinskaya in the first round of the Gippsland Trophy as players began their Australian Open preparations.
The 24-year-old will play world number 48 Coco Gauff next in Melbourne.
American Gauff, who reached the fourth round of the Australian Open in 2020, battled past Switzerland's Jil Teichmann 6-3 6-7 (6-8) 7-6 (7-5).
Gauff squandered a 4-2 lead in the second set and a 4-1 advantage in the third before eventually winning in two hours and 47 minutes.
British number one Johanna Konta, who had a first-round bye, will play America's Bernarda Pera.
