Minnen won 6-4, 6-4 over Margarita Gasparyan in the second round of 's-Hertogenbosch on Wednesday.
Minnen, ranked No. 139, has had some success on the ITF level this season, but she's making a breakthrough at the WTA level in Netherlands after a nice win over the No. 63-ranked Russian. The 21-year-old Belgian, along with everyone else remaining in the bottom half of the draw, is unseeded.
