In the form of her life and with an inviting draw, Sam Stosur has been presented with a golden opportunity to add a Roland Garros crown to the US Open title she won in 2011.

Stosur’s French Open love affair continued on Tuesday, with Australia’s last remaining hope boldly brushing aside world No.6 Simona Halep to end a four-year Grand Slam quarterfinal wait.

In a match which was stretched out over three days due to repeated rain delays, Stosur, a finalist in 2010, wound back the clock with a brutal display to take the fourth-round clash 7-6(0) 6-3.

And Halep believes if conditions stay the same, as they are forecast to do for the rest of the week, Stosur has the game to go all the way.

“If the courts stay like this she has a chance to go till the end, in my opinion,” Halep said.

“She played really well today, and her ball was heavy today, heavier (than normal).

“(The conditions were) good for her.”

Having dispatched the past two beaten finalists Stosur will now face Bulgarian Tsvetana Pironkova for a semifinal berth.

Stosur owns a 3-1 head-to-head record over the world No.102, who came from a set and a break down to eliminate world No.2 Agnieszka Radwanska 2-6 6-3 6-3.

Despite toppling two high seeds Stosur says she won’t be taking her foot off the pedal on Wednesday – but admits she can take confidence from her historical dominance.

“I know certain things that are going to work very well against her,” Stosur said.

“(But) she’s made quarters of a Grand Slam before and had big wins in her career.

“You can’t take anything lightly (although) it looks like a good matchup. Playing a confident player in the quarters of a slam is never easy no matter what your record is.”

Victory there would set up a semifinal showdown with either fourth-seeded Spaniard Garbine Muguruza or world No.108 Shelby Rogers.
