Serbian fifth seed Jelena Jankovic was outfoxed by Romanian teen-ager Sorana Cirstea's devastating net play Monday and lost 3-6, 6-0, 9-7 in the French Open fourth round.
Jankovic, who had reached the Roland Garros semi-finals for the past two years, stormed through the first three games before being broken in the seventh. She immediately broke back and claimed the set when 19-year-old Cirstea hit long.
The former world number one, who received treatment for a blister on a toe on her left foot while trailing 3-0, never got into the second set as Cirstea made regular charges to the net to send a series of winners past her.
Jankovic served for the match in the 11th game of the third but the tenacious world number 41 broke when the Serb hit long. Cirstea unleashed a sizzling crosscourt backhand to reach her first Grand Slam quarter-final against Australian 30th seed Samantha Stosur, who beat France's Virginie Razzano 6-1, 6-2.
