Ana Ivanovic's Toronto Cup title defence came to an abrupt end with a 6-3 6-1 second-round loss to qualifier Yan Zi of China. The Serb was joined at the exit door by Russian fifth and eighth seeds Anna Chakvetadze and Elena Dementieva and Czech No. 16 Lucie Safarova.

Fresh from collecting her second title of the season in Los Angeles on Sunday, Ivanovic was unable to carry the momentum to Canada, the 169th-ranked Yan disposing of the world number four in just 65 minutes.
