Oudin is out as Wozniacki reaches first Grand Slam semi-final

 IT'S hard to dislike a Dane - especially Caroline Wozniacki - but the world number nine is now public enemy number one in New York.

NEW GROUND: Caroline Wozniacki will make her Grand Slam semi-final debut at the US Open in New York

Wozniacki, 19, ended the improbable run of American teenager Melanie Oudin the quarter-finals of the US Open at Flushing Meadow.

She booked her first appearance in a Grand Slam final with a 6-2, 6-2 win over the 17-year old.

And she will now face another teen, unseeded Belgian Yanina Wickmayer, who beat Kateryna Bondarenko 7-5, 6-4.

"She had the entire crowd on her side, so maybe I'm not very popular right now," joked Wozniacki.

"I've never passed the fourth round before. When I made the quarter-finals I was so happy. Now I'm in the semi-finals and hopefully I can try and win the next match so this just keeps getting better."

Oudin, who leaves New York with the big-name scalps of Elena Dementieva, Maria Sharapova and Nadia Petrova, insisted she had no complaints with her defeat.

"This has been a great experience for me, I've had a great run," she said.

"Caroline played a fantastic match, she's such a strong player and gives you nothing for free. I hope to come back next year and do even better."

Wozniacki will start favourite in the semi-final against the unknown Wickmayer - who had been overshadowed by fellow Belgian Kim Clijsters in this tournament.

Clijsters, in a comeback slam after two years on the sidelines, plays Serena Williams in her quarter-final later tonight.

"Playing semis in a Grand Slam is amazing," said Wickmayer,

"Before this my best was second round but when you get to the fourth round you start surprising yourself and I've been staying pretty calm. Hopefully that continues."

Elsewhere, Guernsey's Heather Watson joins former junior Wimbledon champion Laura Robson in the next round of the girls' singles.

Watson beat American teen Courtney Dolehide 6-3, 6-2 while Robson plays Belgian 12th seed Tamaryn Bendler for a quarter-final place later today.
