Swiatek has become the fourth-youngest multiple Roland-Garros champion in the Open Era after Monica Seles, Steffi Graf and Chris Evert and is the youngest to claim two majors since Maria Sharapova in 2006.
She is the first woman to win six titles in a row since Justine Henin in 2007/2008 and hasn't lost a match since February.
The 21-year-old has not conceded a set or more than five games in her past nine finals and in a remarkable display of poise she never needed to deviate too far from her assertive game plan on Court Philippe-Chatrier to extend that record.
“I’m pretty happy every piece has finally come together... Two years ago winning this title was something amazing,” Swiatek said.
“Honestly, I wouldn’t expect it ever but this time I feel like I worked hard, did everything to get here. Even though it was pretty tough, the pressure was big…
“Really I have extra motivation every time I’m coming here, so I love to be back.”
