Going into the tournament with her lowest seeding at a major in five years, Stosur cut a relaxed figure in the opening rounds, and looked particularly impressive in dispatching the in-form Monica Puig for the loss of just two games.
The Turning Point
Victory for the Australian, who was a runner-up in Paris four years ago, maintained her unbeaten record against Cibulkova, whom she has now not dropped a set against in five meetings. Stosur's big forehand and heavy topspin have always troubled the Slovak and it was no different in their latest encounter, on Suzanne Lenglen.
Despite surrendering an early break advantage, Stosur played the more assertive tennis in the first set and was rewarded when she closed it out after 45 minutes. There were some fierce exchanges in the second as Cibulkova displayed her fighting qualities but a focused Stosur, who committed just 12 unforced errors, kept her nose in front and converted her second match point with an ace down the T.
By The Numbers
The result, which follows hot on the heels of the exits of Serena Williams, Li Na and Agnieszka Radwanska, throws the draw even wider open and sees Stosur advance to the fourth round of a major since 2012. Underpinning Stosur's success was a dominant serving display that saw her broken just once, win 72% of the points behind her first serve and hit 10 aces.
"It's very pleasing. I'm really happy with the way I played today and I think it's the first time I won three matches in a row for a while, too," Stosur said. "And to keep playing well, you know, when your opponent is putting you under pressure at certain times in the match, it's really amazing to come out of those as well.
"I just love playing here. I've had some really great moments here and some of the best matches of my career actually. Hopefully I can still have a few more matches like this."
