South Korea's An Se-young won the Olympic badminton women's singles title on Monday in Paris, beating China's He Bingjiao 21-13, 21-16 in the final.
Indonesia's Gregoria Mariska Tunjung won the bronze by default after Spain's Carolina Marin retired from her semifinal through injury.
The 22-year-old An is the dominant force in women's badminton and won eight titles on badminton's world tour last year.
She became South Korea's first Olympic women's singles champion since 1996.
He, who lost the bronze medal match at the Tokyo Olympics three years ago, progressed to the final when her opponent Carolina Marin retired from their semifinal after collapsing with a knee injury.
She was looking to win China's third badminton gold of the Paris Games, following successes in mixed and women's doubles.
He made An work for every point in a fast and furious first game, until the South Korean began to ease ahead towards the finish.
She closed the first game out when He smashed a return into the net.
An quickly gained the upper hand in the second game and her march towards the title began to look inevitable.
He slowed her progress with an incredible smash return midway through the game but An would not be stopped and she sealed the win on her third match point.
