Samantha Stosur has booked a quarter-final clash with world number two Maria Sharapova at the Pan Pacific Open in Tokyo.
Stosur defeated Slovakia's Dominika Cibulkova in straight sets, 6-4, 7-5 while Sharapova advanced after beating Czech Lucie Safarova 6-2, 7-6 (7-5).
The Australian has won just once in 11 matches against Sharapova, in Istanbul last October, but is confident she can improve on her record.
"I thought I played really quite well, so I'm looking forward to the next one," Stosur said.
"She's one of the players I've struggled with in the past and only beaten her once, so it is always a really good challenge to play her."
Top-seed Victoria Azarenka also eased through to the last eight beating Italy's Roberta Vinci 6-4, 6-2.
In the match of the round, Caroline Wozniacki beat former French Open champion Li Na 4-6, 6-3, 6-4.
Elsewhere, Australians Matthew Ebden and Marinko Matosevic both went out early in Asian tournaments.
Matosevic lost 6-3, 6-4 to Ivo Karlovic in the first round of the Thailand Open and Ebden fell 7-5, 6-2 to French seventh-seed Julien Benneteau in the second round of the Malaysian OpenTags: sport, tennis, japan First posted September 27, 2012 08:34:47
