Anastasia Pavlyuchenkova completed her giant-killing week at the Open GDF SUEZ in Paris by claiming a three-set win over third seed Sara Errani in Sunday's final.
The 22-year-old Russian defeated seventh seed Carla Suarez Navarro, fourth-seeded Angelique Kerber and top seed Maria Sharapova en route to the final, where she again looked in formidable form as she defeated Errani 3-6 6-2 6-3 for a sixth career WTA title.
It was not all plain sailing for Pavlyuchenkova, with energetic Italian Errani edging the first set on the back of a run of seven straight games which overturned an early 3-1 deficit.
That winning streak also saw Errani move into a 2-0 lead in the second set, but that was the cue for Pavlyuchenkova to respond in kind with seven games in a row of her own to take the match to a decider.
Errani hit back with three successive games to take the initiative in the third set, but another run of games in Pavlyuchenkova's favour - five on this occasion - saw her to a victory in which the powerful right-hander sent down 48 winners.
Pavlyuchenkova told the WTA Tour website: "When I lost seven games in a row I don't really know what happened - maybe I was a little stressed because I was missing some shots and she was so solid.
"Also, I was serving so well throughout the tournament and there were times today where I was really struggling on serve.
"But I knew it was from my side, so if I just focused and kept fighting I could get it back."
