There will be two first-time quarterfinalists vying for one of the final four spots at this year’s unpredictable U.S. Open. Well, at least on the women’s side.

Denmark’s Caroline Wozniacki held her nerves to edge former champ Svetlana Kuznetsova 2-6, 7-6 (5), 7-6 (3). So, it will be a battle of teenagers when Wozy faces American sensation Melanie Oudin.

Imagine that. Who ever would’ve believed it? One will make the semis and play either Yanina Wickmayer or Kateryna Bondarenko guaranteeing that someone will be a first time slam finalist.

Pretty exciting stuff. We’re going to check out the men’s Round of 16 match-up between Novak Djokovic and Radek Stepanek.

We’ll have more later on Wozniacki’s big win, beating one of the best players on the WTA Tour.
