Emma Raducanu, the 18-year-old British, completed a shocking run through the U.S. Open with a straight-sets victory over Leylah Fernandez of Canada on Saturday for a title that will surely go down as one of the great underdog journeys in the history of sports.

Raducanu, ranked 150th in the world and barely known two weeks ago, became the first player to win a Grand Slam title after surviving the qualifying tournament, a scenario that may very well never be repeated. She also became the first woman from Britain to win a Grand Slam singles title since Virginia Wade won Wimbledon in 1977.

She became the first qualifier in history, male or female, to reach a major final, and win a major title, and the first singles qualifier to ever reach the semifinals at the US Open. She became the first female player since Venus Williams in 1997 to reach the US Open final in her debut appearance. Qualifier is a player who reaches the tournament's main draw by competing in a pre-tournament qualifying competition, rather than automatically by virtue of their world ranking, by being awarded a wild card, or other exemption.
