Britain's Emma Raducanu (19) defeated Magda Linette 6-2 6-2 to secure her spot in the semi-finals of the Korea Open on Friday, reaching the last-four of a tournament for the first time since her triumph at last year's US Open.
Raducanu won a remarkable 96% of her first-serve points in the quarter-final clash against Poland's Linette.
The teenager is yet to drop a set at the WTA 250 tournament in Seoul.
She will face Jelena Ostapenko, the Latvian defeated Victoria Jimenez Kasintseva.
