SAM Stosur will try to blast slightly built Italian Sara Errani off the court in tonight's French Open semi-final.
Chasing a spot in her second final at Roland Garros, the Australian No.6 seed used her excellent serve and dominant forehand again to brush aside diminutive Slovakian Dominika Cibulkova 6-4 6-1 in yesterday's quarter-final.
In what might have been a back-handed compliment, Cibulkova said Stosur played more like a man.
"Her topspin and her serve, she played like a man, and it's really hard to play against a man," the 15th seed said. "It was driving me crazy on the court today. So it was really, really hard. Really tough."
Errani is only slightly taller than Cibulkova but used plenty of guile to overcome her quarter-final opponent, German 10th seed Angelique Kerber, 6-3 7-6.
Errani made the semi-final at this year's Australian Open, but had an appalling 0-28 record against Top 10 players before downing Kerber.
Acknowledging she didn't have the power to go head-to-head against Stosur, the Italian said she would have to "think more" in the semi-final.
The Australian, who was beaten in straight sets by Francesca Schiavone in the 2010 French Open final before winning the US Open final last year, hasn't dropped a set in the tournament.
Stosur has a 5-0 record against Errani, but said she wouldn't take her opponent lightly.
"She's going to be tough," Stosur said.
"She's not very tall, but it doesn't mean that it's easy.
"She's played very well to get to this point so you have to be ready."
In tonight's men's semi-final, top seed Novak Djokavic and Roger Federer will clash after both players survived massive scares in their quarter-finals.
Djokavic saved four match points against Frenchman Jo-Wilfried Tsonga before winning 6-1 5-7 5-7 7-6 6-1.
And Federer had to come from two sets down to get past his 2009 US Open conqueror Juan Martin Del Potro in five sets, 3-6 6-7 6-2 6-0 6-3.
