Paris - Australian veteran Sam Stosur battled into her fourth French Open semi-final on Wednesday, beating 102nd-ranked Bulgarian Tsvetana Pironkova 6-4 7-6(6) after a dramatic turnaround in the second set tiebreak.
Pironkova came close to taking a grip on the match when she held three break points for a 5-2 lead in the first set, but the number 21 seed launched an impressive comeback by winning the next five points.
The 32-year-old Stosur, who lost the 2010 Paris final to Italy's Francesca Schiavone, also showed her greater experience in the second set, winning the decisive tiebreak 8-6 after chasing down a 5-1 deficit.
In the semi-final she will face Spanish fourth seed Garbine Muguruza, who ended the run of another low-ranked player, 108th-ranked American Shelby Rogers.
