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.”

Incredible.
