Canada's Felix Auger-Aliassime advances to National Bank Open quarters-finals

Canada's Felix Auger-Aliassime is moving on to the quarterfinals at the National Bank Open after a 6-3, 6-4 victory over Britain's Cameron Norrie at IGA Stadium.

The sixth seed from Montreal broke Norrie's serve late in the second set before serving out for the victory.

Norrie, the ninth seed, beat the Canadian in the semifinals last week in Los Cabos, Mexico. It was his first victory over Auger-Aliassime in five tries on the ATP Tour.

Ruud, who will play Auger-Aliassime in the next round, is the highest seed left in the singles draw. Top-seeded Daniil Medvedev of Russia, No. 2 Carlos Alcaraz of Spain and No. 3 Stefanos Tsitsipas of Greece lost their opening matches.

The Ruud-Bautista Agut match was completed over four hours after its initial start time. Mid-afternoon thunderstorms caused a delay of just over an hour.

World No. 1 Iga Swiatek was stunned by Beatriz Haddad Maia 6-4, 3-6, 7-5 on Thursday at the National Bank Open.

The unseeded Haddad Maia had already upset 13th-seeded Leylah Fernandez of Laval, Que., the previous day.

She will face the winner of the Round of 16 match between Belinda Bencic and Garbine Muguruza in a quarterfinal on Friday.

Serving was an issue for Swiatek with nine double faults to Haddad Maia's one.

Haddad Maia, ranked No. 24 in the world heading into the tournament, won the match point when Swiatek put a forehand long and wide.
