Halep trying to make Romanian history at French Open
Romania's Simona Halep returns the ball to USA's Sloane Stephens during their French tennis Open round of sixteen match at the Roland Garros stadium in Paris on June 2, 2014 winning 6-4 6-3 - by Patrick Kovarik
The highest ranked player left in the women's draw equalled her best showing at a Grand Slam, as she racked up a perfect six breaks from six opportunities in a match lasting 1hr 18min.
She is attempting to become the first Romanian to reach the final on the Paris clay since her manager Virginia Ruzici lost to Chris Evert in 1980.
That defeat, against the American icon, came two years after Ruzici became the only Romanian woman to lift the French Open title.
"I'm really happy to reach the quarter-finals in Paris for the first time in my life," said Halep, who also reached the same stage at this year's Australian Open where she was beaten by Slovakian Dominika Cibulkova.
"I feel confident and I like the clay but I want to go further even if I know it's going to be very tough in the next round."
She now faces either Russian 2009 French champion Svetlana Kuznetsova or Czech Republic's 24th seed Lucie Safarova for a place in the semi-finals.
