2011 Australian Open – Women's singles
Kim Clijsters won her first Australian Open title and her fourth Grand Slam overall by beating Li Na 3–6, 6–3, 6–3 in the final to capture the women's singles tennis title at the 2011 Australian Open. Li became the first Asian player to make the final of a Grand Slam in singles. Though she lost in the final, she would go on to win the French Open a few months later. Serena Williams was the two-time defending champion, but a foot injury during the middle of the 2010 season prevented her defending  the title. The fourth round match between Svetlana Kuznetsova and Francesca Schiavone, which lasted 4 hours and 44 minutes, was the longest women's singles match in Grand Slam, with Schiavone winning it in the third set, 16–14. Notably this was the last Grand Slam that two former world No. 1 players Justine Henin and Dinara Safina would ever play, being forced into Henin's second retirement due to an elbow injury and Safina's back injury. This was also the first Grand Slam that Caroline Wozniacki competed as the World No. 1; she lost to Li in the semifinals
