Leylah Fernandez battled back to upset Elena Rybakina and Anna Kalinskaya ousted a resurgent Emma Raducanu to set up the DC Open final.

Raducanu effectively overtook Boulter with her victory over Naomi Osaka, the four-time major winner, in the second round in Washington. It followed a similarly impressive victory over the seventh-seeded Ukrainian Marta Kostyuk in Raducanu’s first match.
