All　Chinese　exit　US　Open　tennis

 Peng　Shuai　hits　a　return　during　her　first　round　6-1,　3-6,　4-6　loss　over　Italian　Flavia　Pennetta　at　the　2007　U.S.　Open　tennis　tournament　women's　singles　in　New　York　on　Wednesday,　August　29,　2007.　Aug.　29　-　Chinese　tennisplayer　Peng　Shuai　was　defeated　by　Italy's　Flavia　Pennetta　6-1,　3-6,　4-6　after　the　two　battled　each　other　in　the　first　round　of　the　2007　U.S.　Open　women's　singles　on　Wednesday.　
　With　Peng's　compatriot　Yan　Zi　ousted　by　Russian　Ekaterina　Bychkova　one　day　before,　the　last　Chinese　bowed　out　of　the　annual　Grand　Slam　Tennis.　
　Peng　Shuai　started　with　an　easy　6-1　win　in　the　first　set　of　the　match　despite　being　knocked　out　by　Pennetta　2-6,　3-6　in　the　third　round　of　last　year's　Wimbledon　Open.　
　However,　the　hot　favorite　tennis　player　was　influenced　by　an　unexpected　and　long　medical　treatment　pause　at　the　beginning　of　the　second　set　while　her　opponent　seized　two　break　points,　winning　it　6-3.　
　The　Chinese　girl　faced　tough　challenges　in　the　last　set　competition.　After　four　deuces,　Peng　Shuai　failed　to　save　her　fifth　service　game,　finally　falling　to　a　4-6　loss.　
　The　Italian　winner　will　meet　another　qualifier,　No.　13　seed　Nicole　Vaidisova　of　the　Czech　Republic,　in　the　coming　second　round.
