NEW YORK — American teenager Victoria Duval stunned 2011 U.S. Open champion and No. 11 seed Sam Stosur in the first round Tuesday.
The 17-year-old qualifier, ranked 296th, won 5-7, 6-4, 6-4, leaping in celebration after converting her fourth match point with a forehand winner.
Duval was playing in just her second Grand Slam match. Stosur, a Tampa resident, was Duval's first top-20 opponent.
"I played amazing," Duval said. "The whole match was just an incredible match."
Duval was born in Miami but lived in Haiti until she moved back to the United States at age 8. She eventually moved to Bradenton to train with Nick Bollettieri as an adolescent.
Throughout the match, Duval's father, Jean-Maurice Duval, stood in a corner of the arena, along with 13 members of Duval's friends and family.
"She said to me this morning, 'Dad, we are going to make it. I'm going to play all my game,' " Jean-Maurice Duval said.
Fans migrated toward him to offer congratulations.
"Kenbe l'ale!" a woman said to him, offering her hand.
"It means, 'Keep it going,' " Duval said, translating from Haitian Creole.
With a pipsqueak voice, glasses and a wide grin, Duval's motto is, "have fun." She said Gary the Snail is her favorite character on SpongeBob SquarePants — "Gary doesn't get enough credit," she insists. And she giddily revealed that rap star Lil Wayne mentioned her on Twitter.
"I don't have Twitter," Duval said. "But I'm going to have to look that up."
Stosur had 10 double-faults and 56 unforced errors.
"I'm not going to be a sore loser and say she didn't do anything," Stosur said. "But, you know, I think I certainly helped her out there, that's for sure."
No. 7 seed Petra Kvitova, struggled for a set, but settled down for a 6-2, 3-6, 6-1 victory over Misaka Doi.
Kvitova, a one-time Wimbledon champion who has not found similar love for or success at the Open, explained her struggles with the New York atmosphere: "It's too much crowdy for myself, I think."
In men's play, No. 7 seed Roger Federer got his first Grand Slam victory since losing in the second round at Wimbledon. Federer beat Grega Zemlja 6-3, 6-2, 7-5.
"I was happy the way I played, you know, overall,'' he said. "I mean, it's a first round, after all."
Top-seeded Novak Djokovic saved seven of eight break points in a 6-1, 6-2, 6-2 victory over former junior world No. 1, Ricardas Berankis.
"I played every point like it's a match point," Djokovic said.
No. 14 Jerzy Janowicz was treated for back pain during a 6-4, 6-4, 6-2 loss to 247th-ranked qualifier Maximo Gonzalez.
John Isner of Tampa needed 15 minutes to win the first set and beat Filippo Volandri 6-0, 6-2, 6-3.
