And he was installed as the tournament favorite immediately after the draw, when he landed on the opposite side to top-ranked Nadal, Wimbledon champion Andy Murray and 17-time major winner Roger Federer. Nadal plays 22-year-old Bulgarian Grigor Dimitrov in the quarterfinals on Wednesday, when Murray and Federer go head-to-head.
Berdych, the 2010 Wimbledon finalist, reached his first Australian Open semifinal when he beat No. 3-seeded David Ferrer 6-1, 6-4, 2-6, 6-4. Ferrer, a semifinalist here in two of the previous three years, was clearly frustrated at times, yelling at himself after points and bumping into a line judge after breaking Berdych in the sixth game of the third set.
The 31-year-old Spaniard said it was an accident in a "nervous moment," as he went for his towel, saying "It was nothing ... I say to him excuse me after that."
He could face a sanction for coming into contact with a match official.
On the women's side, 19-year-old Canadian Eugenie Bouchard reached the semifinals in her first trip to the Australian Open, beating Ana Ivanovic 7-5, 5-7, 6-2 to set up a showdown with two-time finalist Li Na.
Ivanovic had beaten top-ranked Serena Williams in a massive upset in the previous round, and No. 3 Maria Sharapova was also out in the fourth round. Two-time defending champion Victoria Azarenka is into the quarterfinals on Wednesday.
Bouchard, the first Canadian to reach the Australian Open semifinals, played with real composure against former 2008 French Open champion Ivanovic, who started the season with a title at Auckland, New Zealand.
That result means two-time Australian Open finalist Li, who beat Flavia Pennetta 6-2, 6-2 in an earlier quarterfinal featuring two women who'll turn 32 next month, will have to face a teenager for the third time in the tournament.
Bouchard went to the net 24 times and won 19 of those points. She broke Ivanovic's serve seven times, including the last game, and had to sit through a lengthy time out when she was leading 4-3 in the second set while her opponent received treatment.
"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," she said. "I always expect myself to do well. "
