Canadian teenager Victoria Mboko upset top-seeded Coco Gauff 6-1, 6-4 on Saturday night to reach the National Bank Open quarterfinals.

Victoria Mboko's stellar run at the National Bank Open hit a new level Saturday. The Canadian rolled to a 6-1, 6-4 victory over No. 1 seed Coco Gauff of the United States, winning the women's singles match in just 62 minutes to advance to the quarterfinals at the WTA 1000 tournament.

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.
