Italy's Sara Errani showed no signs of ending her giant-killing run at the French Open as she cut 10th seed Angelique Kerber down to size with a 6-3, 7-6 (2) win to reach her first Grand Slam semi-final on Tuesday.
Errani had already dumped out former champions Ana Ivanovic and Svetlana Kuznetsova in the two previous rounds and she proved that those wins were no fluke as she recorded her first win over a top 10 player after 28 failed attempts.
Left-hander Kerber had been bidding to become the first German woman to reach the semis since Steffi Graf in 1999 but she was outwitted and out-punched by the 21st seed.
Errani ended a scrappy second set, which featured six successive breaks and eight in total, with an unreturnable serve to book a semi-final date with 2010 runner-up Samantha Stosur.
Tricks of the trade
Australian sixth seed Stosur had more tricks in her bag as she reached the semi-finals of the French Open for the third time in four years by outfoxing Slovakian 15th seed Dominika Cibulkova 6-4, 6-1.
The US Open champion advanced into the last four without dropping a set.
Stosur, who reached the semi-finals in 2009 and the final in 2010 in the claycourt grand slam, prevailed on composure and tactical finesse, using her kick-serve to stave off nine of 10 break points.
She struggled at first with her opponent's power but Cibulkova collapsed after losing the opening set, with Stosur winning six games in succession to wrap it up after 85 minutes.
