NEW YORK: Emma Raducanu, an 18-year-old British qualifier, is living a US Open dream as astonishing as anything one might see down the road on Broadway.

Raducanu, ranked 150th, became the first qualifier to reach the US Open women’s semifinals on Wednesday by defeating Swiss 11th seed Belinda Bencic, the Tokyo Olympic champion, 6-3, 6-4 at Arthur Ashe Stadium.
