Dinara Safina has staged another remarkable comeback to reach the semi-finals of the French Open with a 4-6 7-6 6-0 win over fellow Russian Elena Dementieva.
Two days after Marat Safin's younger sister knocked out world number one Maria Sharapova in the fourth round, she knocked out seventh seed Dementieva in almost identical fashion.
In both matches, Safina was a set and 5-2 down before she broke, then saved a match point on her serve at 5-3, broke again, and then won the ensuing tie-break.
The 13th seed, who prevailed after a two hour 36 minute-battle, will meet compatriot and fourth seed Svetlana Kuznetsova for a place in Saturday's final.
Fourth seed Kuznetsova earlier beat Kaia Kanepi of Estonia 7-5 6-2.
