Bouchard through to semi-finals

Canadian teenager Eugenie Bouchard will clash with fourth seed Li Na in the semi-final of the Australian Open.

The 19-year-old Bouchard recovered from losing the first set to oust Ana Ivanovic, while Na, last year's beaten finalist, recorded a comprehensive win over Flavia Pennetta in the last eight.

Bouchard, who was named the 2013 WTA newcomer of the year, held her nerve to record a hugely impressive in a 5-7 7-5 6-2 victory.

Ivanovic had gone into the game on the back of tough wins over Sam Stosur and Serena Williams - and the Serb needed lengthy injury time-out in the second set.

Bouchard, though, took full advantage to reach her maiden grand slam semi-final.

"I feel like she was playing really well and I had to keep fighting and playing aggressive," she said.

"I feel like I stepped it up in the second and third sets."

Li remained on course for a third Australian Open final appearance with a 6-2 6-2 win over Pennetta.

The 31-year-old, who lost to Victoria Azarenka 12 months ago, needed just an hour and seven minutes to complete a one-sided victory.

Li, who saved a match point against Lucie Safarova in the third round, said: "I've got a lot of confidence because I was match point down, I came back to win the match.

"I even more believe in myself. I wish I can take one more step this year."
