Coco Gauff’s Canadian Open campaign came to an end in the fourth round as she geared up for the US Open. The world number two had not played since her early exit at Wimbledon, where Dayana Yastremska knocked her out in the opening round.

Victoria Mboko, the 18-year-old Canadian tennis player, defeated champion Coco Gauff at the Canadian Open in Montreal on Saturday.

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.
