The women's doubles Olympic champion, who made the history for China pairing with compatriot Li Ting in Athens 13 months ago, converted two match points to win here on Tuesday, beating the 1.54-meter-tall Tatiana Panova from Russia 6-3, 6-4.
Panova committed five double-faults in the second set, while the much taller Sun stormed to win using her advantage on serve.
The most wasted of all days is one without laughter....
Even if you're on the right track, you'll get run over if you just sit there
Enjoy This Moment!!
HEALTH and HAPPINESS to EVERYONE
