19-year-old Eugenie Bouchard has qualified for her first ever Grand Slam semi-final after a 5-7 7-5 6-2 win over Ana Ivanovic in Melbourne.

The Canadian teenager found it hard against the woman who conquered Serena Williams last week, but found an advantage following a medical time out to set up a semi-final against fourth seed Li Na.

Two-time finalist Na had an easier time in her quarter-final, playing out a straight sets win over 28th seed Flavia Pennetta. The 2013 finalist now believes that she can make the final again this year, after almost crashing in her third round match against Lucie Safarova last week.

"I've got a lot of confidence because I was match point down and I came back to win that match," said the 31-year-old, according to BBC Sport.

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

In today's men's singles quarter-final, Tomas Berdych got the 6-1 6-4 2-6 6-4 win over world number three David Ferrer to reach his first Australian Open semi-final.

He will face the winner of the evening session clash between defending champion Novak Djokovic and eighth seed Stanislas Wawrinka. And, the Swiss star is certainly giving the world number two a run for his money, having moved into a two sets to one lead.
