 |  World No. 1 and defending champion  Dinara Safina was knocked out in the second round of the Toray Pan Pacific Open  yesterday by Taiwanese qualifier Chang Kai-chen (張凱貞) only hours before her  fellow Russian Svetlana Kuznetsova was ousted in another upset result. Safina was serving for the match in the third set when she double-faulted to  give up a break. Chang, ranked 132nd and playing only for the fourth time in a  WTA main draw, held her own serve and then broke Safina again for a 7-6 (7/5),  4-6, 7-5 win to reach the third round of the US$2 million  tournament. |
