The world No.80, who has played three three-setters this week at Melbourne Park, saw off for the 23rd seed Anastasia Pavlyuchenkova in the first round.
The world No. 258 Simona Halep, who beat Bethanie Mattek-, is to be Wickmayer’s fourth round opponent. The Romanian beat the American Bethanie Mattek-Sands in two sets 6-4, 7-5 on Friday.
A former US Open semi-finalist, Wickmayer has won all three of their previous meetings - although admittedly they came in 2010-12.
