Li smiling all the way to lounge

The Hisense Arena has become a happy hunting ground for Li Na.

The Chinese star, who always enjoys solid support and boasts a decent record at Melbourne Park, couldn't help but smile on her way back to the players' lounge after beating Olga Govortsova of Belarus to reach the third round at the Australian Open.

"I was so happy that even my coach Carlos and husband, Jiang Shan, felt I was weird after they saw me laughing in the lounge," said a grinning Li on Wednesday after her 6-2, 7-5 victory on a court where she hasn't lost a match since 2005.
