Li Na is a maverick. Who else would stand up to the centralized Chinese sports system as Li did, back in 2008, when she pushed for more control over her career? Li persuaded the Chinese Tennis Association (CTA) to start the “fly alone” policy, which gives players more independence. Now they keep more of their money, giving just a fraction of their earnings to the CTA, compared with the bulk before. Rather than let the bureaucrats pick her coach, Li went with Jiang Shan, who is now her husband. Li has soared. She’s ranked fifth in the world and won the 2011 French Open, becoming the first Asian-born player to win a Grand Slam singles tournament.

Tennis has exploded in China. The country now has some 15 million tennis players; 116 million people watched Li win the French Open. That kind of exposure is crucial to our sport, and it never would have happened without Li. At tournaments, I’ve seen her charm the crowds. When she smiles, everyone melts. She’s such a breath of fresh air. And like Billie Jean King and Martina Navratilova before her, Li Na has transcended her sport.
