Ivanovic defeats Sharapova in Rome
Maria Sharapova was sent tumbling out of Rome by Ana Ivanovic, who trounced the Russian 6-1 6-4 in the third round.
The Serbian 11th seed beat Sharapova, seeded eighth, for the first time in seven years with a blistering display of power to reach her sixth quarter final of 2014.
Ivanovic will face Carla Suarez Navarro in the semis after the Spaniard was granted a walkover against fourth-seeded Romanian Simona Halep, who pulled out with an abdominal strain.
The last time Ivanovic, 26, beat the Russian was in the semi-finals of the 2007 French Open. She went on to lose the final to Justine Henin.
