NEW YORK (Reuters) -British teen Emma Raducanu became the first qualifier to reach a Grand Slam final by beating Greece's Maria Sakkari 6-1 6-4 in her U.S. Open semi-final on Thursday.

With British tennis royalty Tim Henman and Virginia Wade looking on, Raducanu fended off seven break points across her first two service games and capitalized on a trio of double faults from Sakkari on the way to a 5-0 lead in the first set.
