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