And she made a fast start to life in Seoul on Wednesday, with a routine 6-3, 6-4 win over Romania’s Jaqueline Cristian, the world No41.
She wobbled in the first set, though, fighting back tears on court after a rash of missed serves, before rallying back to a comfortable victory.
Raducanu said afterwards: “I’m happy to have won today. It hasn’t been easy, you know. I’m super pleased with how I came through. Tough conditions, very slow long rallies, long points.”
Krejcikova sits at No39 globally, and launched her own Korea Open campaign with a one-sided opener against Tatiana Prozorova, whom she dispatched in just 76 minutes 6-1, 6-2.
