"I try not to think about the score," Raducanu said. "I just try to focus on collecting points. I'm always concerned when things are going well. I always feel like something could go wrong."
Sixth-ranked Simona Halep withdrew because of a right thigh injury before facing Veronika Kudermetova. Halep won last week in Toronto.
