PRAGUE, Czech Republic - Samantha Stosur's solid run continues at the J&T Banka Prague Open, dismissing Denisa Allertova, 6-4, 6-4, edging into the quarterfinals.

"My serve proved really important," Stosur said during her on-court interview. "I thought I served really well the whole match. I only got broken that one time at the start of the second set. I was really pleased to be able to break back and keep the form going on serve."

Stosur came to Prague having lost her last four matches, causing her to fall outside the world's Top 50 for the first time since 2009. Outlasting an injured Daria Gavrilova in the first round, the Aussie veteran used the experience that took her to a career-high of No.4 to navigate past Allertova.

Playing in front of her home crowd, the 25-year-old Czech star aimed to push Stosur into a deciding set as she took a 4-1 lead in the second. The former US Open champion dug in her heels from there, rolling through the final five games to reach her first WTA quarterfinal of 2018.

It was an impressive display from Stosur, who struck 26 winners to 17 unforced errors and dropped just seven points on serve in the hour and 16 minute clash. By contrast, Allertova hit 13 winners to 25 unforced errors.

Up next for the Aussie is an arguably even bigger hitter in Italy's Camila Giorgi. Giorgi reached the quarterfinals in Prague for a second straight year on Wednesday, defeating lucky loser Tamara Korpatsch, 6-4, 6-2.

"I know she plays very big tennis, absolutely goes for it, and hits the ball very hard," Stosur said. "I saw her play Strycova yesterday, and it was very up and down, so I'm expecting a tough match tomorrow."
