Under pressure Ivanovic advances

Ana Ivanovic admitted that the mental stress she faced on court today far outweighed the physical effort required to defeat Russia’s Nadia Petrova for a place in the Wimbledon quarter-finals.

The 19-year-old Serb progressed to the last eight for the first time in her short career with a 6-1 2-6 6-4 triumph against the 11th seed from Moscow, but the game was a stop-start affair with three rain delays disrupting the flow of the match.
