Caroline Wozniacki US Open
Caroline Wozniacki will be desperate for a place in the US Open finalReuters

Caroline Wozniacki has finally started to show the kind of form which made her the world number one for quite a while not too long ago. That heartbreak with Rory McIlroy now put on the back burner, the Dane has produced some outstanding tennis to zoom all the way into the semifinals of the US Open.

Standing in her way of a Grand Slam final is Peng Shuai, looking to fly the China flag in the absence of the much-loved and equally-successful Li Na.

Wozniacki, seeded tenth, blew away No.13 seed Sara Errani in the quarterfinals, dropping just one game in a mighty impressive performance. Wozniacki probably got the belief and confidence needed to go all the way in a Grand Slam after defeating Maria Sharapova in the fourth round, and if the 24-year-old can stay in the same rhythm then the US Open final will certainly beckon.

"I feel confident and I feel comfortable out there," said Wozniacki. "I have been playing well in these last few months. It's just nice that it's paying off here."

The former world number, who lost in the semifinals in New York to Serena Williams three years ago, though, will know Peng is on an impressive run of her own. Her most impressive win came in the second round, when she put away fourth seed Agnieszka Radwanska, and that too in straight sets.

The 28-year-old is yet to drop a set in the tournament, and Wozniacki will know she will have to be at the top of her game to prevent another semifinals defeat.

"She's been playing well," said Wozniacki. "She's playing aggressively. She she's strong from both sides. She's been serving well. It's going to be a difficult match.

"It's going to be a different match than against Sara. Sara runs a lot of balls down, doesn't make many mistakes. Peng is closer to the baseline, going for her shots more. It's going to be a hard one, but, again, it's going to fun."

Peng, once more, can go into the match with that nothing-to-lose feeling, but it remains to be seen if nerves might play a part in her first ever Grand Slam singles semifinal.

"I dream about it," said Peng ahead of her big semifinal. "Because everybody was like asking me all week, maybe you have a chance to get to quarters, so I was really happy first time in the quarters. And I went to the semis. Of course it is exciting, it is surprising, but it is not like I feel like I cannot."

Wozniacki heads into the semifinal as the clear favourite, but this US Open has already shown the favourite tag means little to nothing.
