The 17-year-old qualifier from Atlanta, who was held hostage at the age of seven and whose father who was dug out of the rubble of the 2010 Haiti earthquake, announced herself on the world stage with a stunning 5-7 6-4 6-4 victory.
"I'm very goofy off the court. I think I'm very much a child at heart. But on the court you have to be a warrior because that's just the sport we are in," Duval said after the first-round win.
Duval's father, Jean-Maurice, was courtside at the Louis Armstrong Stadium when his daughter pulled off the first major upset of the tournament.
Three years ago, his legs were broken, his left arm shattered and seven fractured ribs had punctured his lung after the catastrophic earthquake on the Caribbean island.
A tennis connection played an instrumental part in his recovery with an Atlanta family connected with Duval's club paying to airlift him to a Florida hospital.
That only happened after his passport was also dug out of the rubble and the role of the Kitchen family in her father's rescue was not forgotten by Duval in the biggest moment of her fledgling career.
"Emotionally it was hard at first. But he's as happy as he's ever been. He had a couple of surgeries that helped take the pain away," Duval said.
"We're just so happy that, you know, he's in a good state of mind right now. He's here with us, so it's incredible. We're forever grateful to the Kitchens,” she said.
Duval, who will meet Slovakia's Daniela Hantuchova in the second round, said part of her career ambition was to join the likes of Sloane Stephens in restoring the United States to its position as the dominant power in world tennis.
