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

Emma Raducanu booked her place in the semi-final of the Washington Open for the first time with a 6-4, 7-5 victory over Greece’s Maria Sakkari. The victory, on a day where both players had to battle high temperatures, means Raducanu will overtake Katie Boulter as British No 1 on Monday.

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.
