Here’s the NY Times account of the performance of Melanie Oudin, a 17-year-old from Marietta, Ga., making history at the US Open:

On Monday, Oudin pulled off this scene again at Arthur Ashe Stadium, not only outlasting No. 13 Nadia Petrova, 1-6, 7-6 (2), 6-3, to carry her incredible run into the quarterfinals, but leaving the 27-year-old Petrova dropping her racket in disgust and muttering to herself during a changeover. Until she pounded her final forehand for a winner, Oudin was the picture of concentration and intensity, betraying nothing of the pressure of being the American darling at a tournament she has taken over with her charm.

“It’s kind of hard to explain how I’ve done it,” Oudin said. “Like today, there are no tears because I believed that I could do it. And it’s like now I know that I do belong here. This is what I want to do, and I can compete with these girls no matter who I’m playing. I have a chance against anyone.”

Petrova became the latest to fall in a pile of defeated women’s seeds, a collection of emotional marshmallows who have wilted under their circumstances. In contrast, Oudin has charged into every match, the word “believe” inscribed in her sneakers, and refused to give in.”
