Steffi Graf defeated Martina Hingis in the 1999 French Open women’s singles final.
Graf recovered to win 4–6, 7–5, 6–2. The victory gave her a sixth French Open singles title and her 22nd—and final—major singles championship. It was also her ninth appearance in a French Open final, matching Chris Evert’s Open Era record.
The result was especially notable because Hingis was the world No. 1 and was trying to complete the career Grand Slam. Graf stopped that attempt in a dramatic final after Hingis had taken the opening set. Graf had also beaten two other top-three players during the tournament: Lindsay Davenport in the quarterfinals and Monica Seles in the semifinals.
This match is often remembered as both a landmark victory and the closing major chapter of Graf’s career. She did not win another Grand Slam singles title after 1999. The answer is not one of the other German names listed: Graf was the champion, while the question asks specifically who won the final against Hingis.
