The 17-year-old from Bruges beat the 15-year-old Australian Koharu Nishikawa (ITF 143) with a score of 6-4, 3-6 and 6-2. Her next opponent will be either the American Claire An (ITF 56) or the German Sonja Zhenikhova (ITF 37).
Vandromme plays his first Australian Open. The winner of the last Astrid Bowl was a quarter-finalist last year at Roland Garros and Wimbledon, made the round of 16 at the US Open in her first three Grand Slam tournaments and was again a finalist at the Junior Masters.
