Montreal's Eugenie Bouchard is out of the Australian Open.
China's Li Na defeated Bouchard 6-2, 6-4 on Thursday in the semifinal of the tournament.
The 19-year-old Bouchard is the first Canadian woman to reach the semifinals of a Grand Slam tournament in 30 years.
No. 4-seeded Li, the 2011 French Open champion, is the only major winner and the highest-ranked player still in contention after the fourth-round upsets of Serena Williams and Maria Sharapova and defending champion Victoria Azarenka's quarter-final loss to Agnieszka Radwanska of Poland.
No. 5-seeded Radwanska was playing Dominika Cibulkova in the second semifinal later Thursday.
Li, who lost last year's final to Azarenka, was aggressive from the start against Bouchard, who started nervously and didn't win a point in her first three service games.
