Great Britain’s Emma Raducanu moved through to the quarter-finals at the Korea Open by beating China’s Yue Yuan in straight sets.

Raducanu, 21, seized control of the match by winning six successive games to wrap up the opening set and then take charge of the second.

The 2021 US Open champion, ranked 70th in the world, eventually took her seventh match point to win 6-4 6-3 and reach the last eight in Seoul.

Raducanu will play Daria Kasatkina on Saturday, with the semi-finals also taking place later that day because rain postponed play on Friday.

Russian top seed Kasatkina, the world number 13, beat American Hailey Baptiste 6-4 6-2.

“I think these courts suit [Kasatkina] because they bounce quite a bit,” Raducanu said.

“But for me, every time I get exposure to that top level of opponent, it’s invaluable. It allows me to build confidence. It’s a match where I don’t really have anything to lose.”
