Happy birthday, Li Na! The reigning Australian Open champion turns 32 today. Ranked No. 2 in the world, Li joined the professional ranks in 1999 and became the first Chinese player to win a WTA title in 2004. She has won a total of nine WTA titles, including two Grand Slams (2011 French Open and 2014 Australian Open) and has become one of the most popular public figures in China. Li was one of just four athletes to be named to Time magazine's "100 Most Influential People in the World" in 2013. Due in large part to her affable nature and hilarious post-match interviews, Li is considered among the tour's most well-liked players by fans and peers alike. She is scheduled to compete at Indian Wells, Calif., at the BNP Paribas Open next week.
