Kalinskaya will face Leylah Fernandez, the Canadian, in the final. Fernandez was Raducanu’s opponent at the US Open final, with the Briton defeating her 6-4 6-3 on Arthur Ashe Stadium to clinch the title. Raducanu’s next focus is on Montreal, where she faces Elena-Gabriela Ruse in the first round of the WTA 1000 event.

On a muggy day with the temperature topping 90 degrees Fahrenheit (32 Celsius), Raducanu took a medical timeout while reeling off the last five games of the match after trailing 5-2 in the second set.

Britain's Emma Raducanu qualifies for the semi-finals of the Washington Open after beating wildcard Maria Sakkari in straight sets.
