MONTREAL — Coco Gauff overcame 14 more double faults to beat Veronika Kudermetova of Russia 4-6, 7-5, 6-2 on Thursday in the National Bank Open.
Two days after surviving 23 double faults and a third-set tiebreaker against fellow American Danielle Collins, the top-seeded Gauff rallied from a set and break down against Kudermetova to reach the round of 16.
Gauff, No. 2 in the world behind Aryna Sabalenka, entered the week having lost two straight matches since winning the French Open, falling in her opening matches in Berlin and Wimbledon.
McCartney Kessler of the United States upset fourth-seeded Mirra Andreeva of Russia 7-6 (5), 6-4.
