Ninth seed Caroline Wozniacki joined Kim Clijsters, Serena Williams and Yanina Wickmayer in the semifinals of the 2009 US Open, putting an end to Melanie Oudin's fairytale.

Wozniacki defeated Oudin 6-2 6-2 in the quarterfinals, but still, the world No.70 Oudin gave her career a major boost, to the extent that now we’re reading gossip about her family (her father is seeking a divorce from his wife because she cheated on him with Melanie’s tennis coach).

"I've gone from being just a normal-like tennis player to almost everyone in the United States knowing who I am now," said the 17-year-old Oudin, who had defeated four higher-ranked Russians to reach the quarterfinals.

"It's definitely different but I enjoyed it."

Melanie Oudin won’t have the pleasure of meeting yet another Russian at this US Open, as Caroline Wozniacki of Denmark will be her next opponent, who eliminated the last Russian in the draw, sixth seed Svetlana Kuznetsova.

Ninth seed Caroline Wozniacki reached her first Grand Slam quarterfinal by defeating Kuznetsova 2-6 7-6(5) 7-6(3). Wozniacki converted her third match point, having wasted one at 5-4 and one at 6-5 in the third set.

"I hit too many unforced errors and I couldn't control my emotions. And I wanted it so much, so it was pretty hard to control," world No.6 Kuznetsova said. "All credit to her. But you can't win against anybody with those errors. No chance."

Denmark’s Caroline Wozniacki defended a title for the first time in her career by defeating Russia's Elena Vesnina 6-2 6-4 and winning the New Haven title for the second year in a row.

In the Pilot Pen Tennis presented by Schick final, the world No.23 Vesnina hit three times as many winners as Wozniacki, but ruined the advantage with four times as many errors as Wozniacki.

Second seed Caroline Wozniacki and Elena Vesnina won their semifinal matches at the Pilot Pen Tennis presented by Schick, which were moved indoors due to pouring rain in New Haven.

The world No.9 Wozniacki beat third seed Flavia Pennetta by winning eighth of the nine games after being tied at 4-4 in the first set. The world No.32 Vesnina upset eighth seed Amelie Mauresmo in the semifinals, recovering from a tight first set loss to win 5-7 6-1 6-2. By beating the victor over top seed Svetlana Kuznetsova, Vesnina made her second upset of the tournament (after beating ninth seed Samantha Stosur in the second round).

Vesnina will play only her second career final on the Sony Ericsson WTA Tour, at the same time her second this season, while Wozniacki will play her 11th singles final, and seventh this season.

Flavia Pennetta and Caroline Wozniacki, who seems to be the most popular player for the Sony Ericsson stunts, kick started the Pilot Pen Tennis tournament by playing tennis on a historic American football stadium.

The largest tennis court in the world was laid out inside the Yale Bowl and Wozniacki and Pennetta ran tennis balls down the football field.

"If only all tennis courts were as large as the one at Yale Bowl today, then all of our balls will be sure to go in," said the world No.9 Wozniacki after the extraordinary match.

This is the third stunt created by Sony Ericsson this summer. Last week Ana Ivanovic and Caroline Wozniacki stopped traffic to play in one Toronto street, while Kim Clijsters and Elena Dementieva played in the middle of a fountain. (source: Sony Ericsson WTA Tour)
