New Haven, Connecticut, Aug 26 : Top-ranked Caroline Wozniacki advanced to the semifinals of the New Haven Open on Thursday with a 7-5, 6-3 win over 19-year-old American Christina McHale.
Wozniacki is undefeated after 15 matches at the WTA's final tuneup before the U.S. Open and is the tournament's three-time defending champion.
She broke McHale, playing in her second career quarterfinal match, to win a close first set, and again in the eighth game of the second set.
China's Li Na endured several hours of rain delays and three sets of tennis before advancing in her quarterfinal, 6-4, 3-6, 6-2, over Russia's Anastasia Pavlyuchenkova. Li will play Czech qualifier Petra Cetkovska who beat fourth-seed Marion Bartoli 7-5, 7-5. AP
