'' Often the butt of Li 's sense of humor , her husband was in the stands as China 's pioneering tennis player revealed the impending arrival of the couple 's first child this summer . After retiring in September 2014 due to chronic knee problems , the tennis star has made having a family a priority , telling CNN 's Pat Cash in an interview on Sunday that `` family for me is the most important thing . '' Li triumphed at both the French ( 2011 ) and the Australian Open ( 2014 ) to become the highest ranked Asian player the world has seen , peaking at number two in the world..

We ca n't wait to become parents and start this new chapter together . '' Referring to the Melbourne crowd , she added : `` It really feels like this baby is going to enter the world already having about 15,000 friends . '' Not just 15,000 friends -- there 's also China 's 1.3 billion population after Li 's sporting success made her a household name in the country of her birth . It 's estimated that over 100 million Chinese watched the live TV coverage of her 2011 French Open win , reportedly the biggest TV audience for a single sports event in China . Back at the Australian Open all eyes were on Li after decision to announce her news at the Melbourne event . `` I look forward to spending a few more days in Australia and wish all of the players and the tournament the best of luck ! I ca n't wait to be back ! '' she added on Facebook .
