Australian Samantha Stosur booked her place in the French Open semi-finals with a 6-1, 6-3 victory over Romanian high school student Sorana Cirstea on Wednesday.
The 30th seed, a Grand Slam quarter-final debutante like her opponent, dominated from the start and was gifted her first break in the second game when Cirstea double-faulted and she then cruised through the rest of the first set.
The 19-year-old Romanian seemed more daunted by the occasion than Stosur and failed to find a breakthrough despite finding herself 0-40 on Stosur's serve in the second game of the second set.
Her chance missed, the world number 41 dropped her serve the following game and Stosur held her nerve to set up a last-four date either with world number two Serena Williams or Russian seventh seed Svetlana Kuznetsova.
