Canadian teenager Eugenie Bouchard continues to exceed expectations after securing an Australian Open semi-final place with a win over Serena Williams' conqueror Ana Ivanovic.
The 19-year-old, who beat Ivanovic 5-7 7-5 6-2, will face China's Li Na in her first Grand Slam semi-final.
In the men's competition Tomas Berdych beat third seed David Ferrer 6-1 6-4 2-6 6-4 and will face either Novak Djokovic or Stanislas Warwrinka in the final four.
Bouchard, ranked 31st in the world, came through her closely contested quarter-final tie in a match which was littered with service errors.
In the end Bouchard capitalised after Ivanovic was forced to leave the court for medical treatment and was able to break the former world No.1 upon her return to take the final set 6-2.
Despite Bouchard's career still being in its early stages, the confident Canadian says she still expects to do well.
"It's something I've been doing since I was five years old and working my whole life for and sacrificing a lot of things for. So it's not exactly a surprise. I always expect myself to do well," she said.
"I'm just happy to have gone through this step. I'm not done. I have a match on Thursday. I'm just looking forward to that."
Ivanovic reflected on her performance saying: "I was battling with my right leg since the beginning of the tournament. Then the left one came on today. Despite all that, I was still on court. I was doing my best. Today she was the better player."
The teenager will now look ahead to her clash with two-time Australian Open finalist and world No.4 Li, who had no problem cruising past Italy's Flavia Pennetta 6-2 6-2 to secure her semi-final spot.
Li, 31, who will play in her fourth semi-final in Melbourne, said: "I've got a lot of confidence because I was match point down and I came back to win that match.
"I believe in myself even more. I hope I can take one more step this year."
Berdych meanwhile beat Ferrer 6-1 6-4 2-6 6-4 to reach his first Australian Open semi-final.
The Czech fought for over three hours to secure his place in the championship semis, which has eluded him on three consecutive occasions at Melbourne Park.
The 28-year-old will face either Wawrinka or Djokovic on Thursday.
