Belgian wild card Alison Van Uytvanck turned on the style again in front of her home fans as she dispatched world number 39 Ksenia Pervak 6-3 5-7 6-4 in the first round of the Brussels Open.
The world number 450's only previous tour wins had come in the corresponding tournament last year, when she battled through three qualifying rounds to eventually reach the last 16.
And the 18-year-old showed signs of repeating the feat as she kept her nerve to see off her experienced Kazakh opponent in a tight deciding set, grabbing the single crucial break to win in exactly two and a half hours.
Sixth seed Jelena Jankovic was the day's biggest casualty as she fell 6-2 3-6 7-6 (7/3) to Romania's Simona Halep, who held on in a match that saw a total of 13 breaks of serve and lasted six minutes short of three hours.
Fourth seed Dominika Cibulkova beat Christina McHale of the United States 7-6 (7/1) 6-1, 10th seed Nadia Petrova of Russia saw off Ukraine's Kateryna Bondarenko 6-4 6-4, and Bulgaria's Tsvetana Pironkova beat Elena Daniilidou of Greece 6-1 6-4.
