The conditions were so punishing that the players were granted a break in the locker room before the third set, and when they returned to the court Wozniacki wasted little time, breaking Sharapova to love in the fourth game for a 3-1 lead. She broke the Russian superstar again in the final game to seal the victory and a chance to play 13th-seeded Italian Sara Errani for a semi-final berth.
