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.

This time last year, Mboko was ranked outside the top 300. Now, the 18-year-old Canadian is into the quarterfinals of her home tournament.
