Li Na is a former Chinese professional tennis player, who achieved a career-best ranking of world No. 2 on the WTA Tour on 17 February 2014, but retired from the sport seven months later due to chronic and worsening knee injuries.
Over the course of her career, Li won nine WTA singles titles, including two Grand Slam singles titles at the 2011 French Open and 2014 Australian Open. Li's rise to prominence came after her victory at the former event, which made her the first and only Grand Slam singles champion from Asia. Prior to this, she had already become the first player representing an Asian country to appear in a Grand Slam singles final, a milestone she achieved at the 2011 Australian Open.
Li was also the runner-up at the 2013 Australian Open and 2013 WTA Tour Championships, a three-time quarterfinalist at Wimbledon and a semifinalist at the 2008 Beijing Olympic Games and 2013 US Open. Among her other most notable accolades, she was the first Chinese player to win a WTA tour title at the Guangzhou International Women's Open in 2004, the first to reach a Grand Slam singles quarterfinal at the 2006 Wimbledon Championships, and the first to break into the world's top 10.
Her feats have sparked a major population growth of tennis players in Asia, earning her the reputation as the region's tennis pioneer and trailblazer.
