Australian Open 2011

At 38, Hsieh Su-Wei is the second-oldest woman to win a Grand Slam doubles crown after American Lisa Raymond, who was just eight days older when she found success at the 2011 US Open.

The 38-year-old Australian's greatest moment came when she defeated Serena Williams to win the singles crown at the 2011 US Open, which she described as "the pinnacle" of her career.

Comeback queen Petra Kvitova said she was hurting but still felt like a winner.

Novak Djokovic had won the three-day event earlier in 2011, 2012 and 2013 successively stamping his authority.

The assured Dane, a semi-finalist in 2011 who has never quite lived up to the hype in the majors, annihilated 19th-seeded Magdalena Rybarikova 6-3, 6-0 on Rod Laver Arena in her most impressive performance to date.

While Serena Williams will take on her sister Venus in the Australian Open women's final, Roger Federer will be vying against arch rival Rafael Nadal.

Rafael Nadal will be vying for his second Australian Open title against Roger Federer on Sunday.

Novak Djokovic is Andy Murray's nemesis in Australia, beating him in three of his four losses in 2011, 2013 and now 2015, although he mastered the Serb in his two major triumphs at the 2012 US Open and 2013 Wimbledon.

Li Na is a two-time Grand Slam winner and hugely popular at the Australian Open where she won the title last year and reached the final in 2011 and 2013. She unexpectedly retired in September.

Dual Australian Open champion Azarenka and 2008 French Open champion Ana Ivanovic confirmed their entry alongside five-time Grand Slam winner Sharapova and Australia's 2011 US Open title-holder Sam Stosur.

Serena Williams stretched her career record over Samantha Stosur to 7-3. The Australian stunned Williams in the final of the 2011 US Open, but Williams has now won all three of their meetings since.

Australian Samantha Stosur, who won the U.S. Open women's singles in 2011, won a Grand Slam mixed doubles title for the third time, including with Bob Bryan at Wimbledon in 2008.

Li Na, the 2011 winner and reigning Australian Open champion, went down 7-5, 3-6, 6-1 to France's 103rd-ranked Kristina Mladenovic in the French Open, her first opening-round defeat in eight visits.

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 quarterfinal loss to Agnieszka Radwanska of Poland.
