Sun Shengnan

Sun Shengnan (; ; born 21 January 1987) is a Chinese former tennis player. Her highest WTA singles ranking is 216th, which she reached on 4 April 2011. Her career-high in doubles is 50th, which she reached on 17 September 2007. By March 2006, Sun had won two ITF singles titles and risen to No. 320 in the WTA rankings, and had earned herself a reputation as 'one to watch', having shown plenty of recent promise of further improvement in the preceding year. Career Sun Shengnan began competing on the ITF Circuit at the age of 15, in May 2002. Over the next few months, she won seven matches (mostly in qualifying draws) and lost just five. However, she did not compete again for a whole year after the beginning of August, and thus gained for herself only a lowly end-of-year foothold on the world ranking list at No. 1031. When August finally came around again in 2003, she returned to competition as a 16-year-old at ITF events; and that October she reached the quarterfinal of a $25k tournament at Beijing after being awarded a wildcard entry into the main draw, before losing to Yuka Yoshida. She finished the year with a 5–5 win–loss record after just a few events played. The record of her year-end ranking seems to have been lost by the WTA, but it was undoubtedly an improvement on her 2002 outcome thanks to the quarterfinal finish at Beijing.
