She then headed to Melbourne for the Australian Open, where she was the No. 11 seed. In her opening match, she faced qualifier Katarzyna Piter, defeating the Pole in 54 minutes, dropping just one game throughout the whole match. She next faced the American Varvara Lepchenko where she dropped the first set, but easily won the next two sets. In the third round, she defeated the qualifier Zarina Diyas in two sets, setting up a fourth-round meeting with Jelena Janković. Halep defeated the former number one in the world in three sets and qualified for the first time in her career in the quarterfinals of a Grand Slam.  Halep then lost to eventual finalist Dominika Cibulková. With the points gained at the Australian Open, she moved to number 10 in the WTA Rankings, becoming only the third Romanian player to enter the Top 10, after Virginia Ruzici and Irina Spîrlea.  (Magda Rurac was also ranked in the top 10 in unofficial world rankings in 1948 and 1949, before the existence of WTA rankings).
