American Teenager Victoria Duval Stuns Open Champion Sam Stosur

American teenager Victoria Duval stunned everyone on Tuesday when she defeated 2011 US Open champion Sam Stosur.

Playing in the first round, the 17-year-old American, who is ranked 296th, completed the match with a final score of 5-7, 6-4, 6-4.

The victory arrived during the second Grand Slam match of her career. Last year, Duval lost to another US open champ, Kim Clijsters.

Tuesday’s match was the first time in her career that Duval has faced a top-20 opponent.

After the match, Duval gave her props to Stosur:

“I know she didn’t play her best today, and this is the best I’ve played in my career, so I’m really excited. I just tried to stay in the moment.”

Duval told reporters that while she works hard on the court she’s a total goofball off the court:

“I am very goofy off the court. I think I’m very much a child at heart. On the court, you have to be a warrior because that’s just the sport we are in. Off the court, I think it’s important to have fun and be a good role model for other people. My motto is: Have fun.”

In her last three trips to the US Open, the 11th-seeded Stosur has reached at least the quarterfinals.

Duval was born in Miami but lived in Haiti until she was 8-years-old. Duval now trains in Bradenton, Florida.

It was a tough day for tennis’ top ranked women as number 7 seed Petra Kvitova barely etched out a win against 92nd-ranked Misaki Doi. Kvitova eventually prevailed with a final match score of 6-2, 3-6, and 6-1.

It was a windy day at Arthur Ashe Stadium, a fact that seemed to help younger, less experienced players.

Do you think Victoria Duval has what it takes to claim her first grand slam title?
