Canada's Victoria Mboko stuns No. 1 seed Coco Gauff to reach 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.

Mboko, a rising star who has climbed from a No. 333 ranking to 85th in the world this year, saved all four breakpoints against the world No. 2 Gauff, who committed 22 unforced errors in the fourth-round match at IGA Stadium.

The 18-year-old from Toronto, who entered the tournament as a wild card, is the last Canadian standing in the singles draw, both in Montreal and at the 96-man Masters 1000 event in Toronto.

Mboko became the second youngest Canadian to reach a WTA 1000 quarterfinal since 1990, behind only Bianca Andreescu.

She's also only the second teenager — and first Canadian — to defeat Gauff, as well as the first player this season to not drop a single game on serve against the star American.

After major support for Eugenie Bouchard early in the tournament, the buzz in Montreal shifted around Mboko as the teenage sensation took centre court — and she delivered before a sellout crowd.

"Your support was incredible," Mboko told the crowd in French after a chorus of "Ole, Ole, Ole!" chants echoed around the venue.

"I'm really happy to win today."

Mboko looked ready to meet the moment early, flashing the powerful groundstrokes and blistering serve that have made a mark on the pro tour this season.

Gauff, meanwhile, made unforced error after unforced error, firing some shots long and many more into the net during a swift, 25-minute
