Lexington: American Coco Gauff entered the Top Seed Open quarterfinals as she outclassed No. 2 seed Aryna Sabalenka with 7-6 (2), 4-6, 6-4 scoreline.
The 16-year-old Gauff hit 10 double-faults and was broken seven times.
Gauff was able to hang in there with steady baseline play against the hard-hitting Sabalenka, who had 14 double-faults, including four in one game.
She will next face No. 8 seed Ons Jabeur, who produced 10 aces while eliminating Olga Govortsova 3-6, 6-2, 6-4. Govortsova had been seeking her first WTA quarterfinal since 2014.
The other quarterfinal on that side of the draw will be Marie Bouzkova against Jennifer Brady, who beat No. 6 seed Magda Linette 6-2, 6-3 in Wednesday’s last match.
Bouzkova followed up her upset of No. 3 Johanna Konta in the first round by defeating Anna Blinkova 6-4, 6-2 on Wednesday.
