Britain’s Cameron Norrie has been knocked out of the National Bank Open at the last-16 stage following a 6-2 7-6 (10-8) defeat by Arthur Fils in Montreal.

The French 18th seed looked dominant early on in the Montreal contest, utilising his powerful serve well to wrap up the first set without much hassle.

Norrie stepped up a gear in the second, matching Fils’ power to force a tie-break.

Despite creating two set-point opportunities, Norrie was ultimately unable to convert when it mattered and Fils sealed the win in one hour and 43 minutes.

Norrie knocked out third seed Alex de Minaur in the round prior, turning the tables from match-point down by winning 11 out of the next 13 games to beat the Australian 5-7 7-6 (7-5) 6-1 – a victory that saw him become British No 1 again in place of Arthur Fery – but he was unable to build on that win.

Fils will face Spain’s Rafael Jodar in the quarter-finals, after he upset eighth-seed Jiri Lehecka in straight sets.

Brandon Nakashima and Luciano Darderi also progressed to the next round with gruelling three-set victories over Arthur Rinderknech and Nuno Borges, respectively.

World No 1 Sabalenka suffers US Open build-up setback as Alexandrova beats her in Toronto

World No 1 Aryna Sabalenka suffered a setback in her US ‌Open build-up when she was beaten 7-6 (7-3) 4-6 6-4 by Russia’s Ekaterina Alexandrova in ‌the fourth round of the Canadian Open in Toronto.

The 16th-seeded ​Alexandrova fought a hard battle lasting nearly two-and-a-half hours to secure her quarter-final ​berth.

Sabalenka, a four-time Grand Slam champion and ‌reigning US Open winner, recovered from a set down to force a ​decider but was unable to halt Alexandrova’s aggressive shot-making in the final set.

The Belarusian broke early in the opening set ​before Alexandrova rallied to force a tie-break, ⁠which the Russian won to ⁠move ahead.

Sabalenka responded by seizing control of the second set with a break for a ‌4-3 lead before serving out to level the match.

Alexandrova held her nerve in the decider as Sabalenka’s error count rose. ‌Serving to stay in the match at 4-5, the top seed saved two match points, but a double fault on the third handed victory to the Russian.

“I just tried to play ⁠every single point as if it was ​the last one because with her, you don’t [get] ​a lot of chances during the match,” Alexandrova ​said in her on-court interview.

“Honestly, I was trying not ⁠to think about the score or anything. Just hit the ball, and that’s it.

“I’m super happy that I could win because ⁠after the second set, I thought [the ​chance] was already past me.”

Alexandrova will face Ukraine’s Elina ​Svitolina, who defeated American eighth seed Amanda Anisimova 6-2 6-4, for a place in the ‌semi-finals

Women’s world number one Aryna Sabalenka suffered a surprise defeat in the Canadian Open weeks before she begins her US Open title defence, while Britain’s Cameron Norrie also bowed out in the last 16.

Sabalenka lost 7-6 (7-3) 4-6 6-4 to Russia’s Ekaterina Alexandrova in a match lasting almost two and a half hours in Toronto.

The Belarusian recovered from a set down to force a decider, but a double fault when serving to stay in the match handed the number 16 seed victory.

It is the latest defeat in what has been a difficult summer for Sabalenka, who was knocked out in the quarter-finals and last 16 of the French Open and Wimbledon respectively.

“I just tried to play every single point as if it was the last one because with her, you don’t [get] a lot of chances during the match,” Alexandrova said.

“I’m super happy that I could win because after the second set, I thought [the chance] was already past me.”

The Russian will face Ukraine’s Elina Svitolina for a place in the semi-finals, after she defeated American eighth seed Amanda Anisimova 6-2 6-4.

Third seed Jessica Pegula suffered a first career loss to Diana Shnaider, as the 22-year-old finished both sets strongly to win 6-3 6-3.

The Russian will face Iga Swiatek in the semi-finals, after the seventh seed overcame opening set service troubles to defeat 10th seed Marta Kostyuk 3-6 6-1 6-2.

The six-time Grand Slam winner retired to the locker room after Kostyuk broke her serve four times during a shambolic a 39-minute opening set, but looked much improved when she returned.

In the men’s event in Montreal, British number two Cameron Norrie spurned two set-point opportunities as he was defeated 6-2 7-6 (10-8) by 18th seed Arthur Fils.

Norrie saved three match points in the second set to force a tie-break, but the Frenchman broke his serve to win in one hour and 43 minutes.

Fils will meet Spanish teenager Rafael Jodar in the quarter-finals, after the 19-year-old upset eighth seed Jiri Lehecka 6-3 6-3.

Brandon Nakashima and Luciano Darderi also progressed to the next round with gruelling three-set victories over Arthur Rinderknech and Nuno Borges respectively.

Italian Darderi used a mid-match changeover to enjoy an espresso as he battled to a 4-6 6-3 7-5 win.
