Emma Raducanu reached the semifinals at the D.C. Open — the biggest tournament where she’s made it that far since her surprising 2021 U.S. Open title — by eliminating Maria Sakkari 6-4, 7-5 on Friday.

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.

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