Gauff, the 21-year-old world No. 2, survived another day of subpar serving and scraped herself off the pavement of the Canadian Open to win her second consecutive three-set match, beating Veronika Kudermetova of Russia 4-6, 7-5, 6-2. It was Gauff’s ninth win in 10 three-set matches this season.

Coco Gauff was once again denied a berth in the semifinal of the Canadian Open. This time, the opponent was teen sensation Victoria Mboko, who breezed past the two-time Grand Slam singles champion with a 6-1, 6-4 scoreline.

Victoria Mboko shocked French Open champion Coco Gauff at the Canadian Open on Saturday evening. The 18-year-old defeated the American top seed 6-1, 6-4 in just over an hour to reach her first Canadian Open quarter-final.
