Stosur likes odds as Serena Grand Slam spoiler

Samantha Stosur, the last woman to beat Serena Williams at the US Open, likes her chances of disrupting the American star's calendar Grand Slam bid if she gets the chance.

"I've always actually quite enjoyed playing Serena. I've got a game that disrupts her," Stosur said Wednesday. "You have to have the game. My game matches up well against Serena. I've got the kind of weapons that can bother her."

And the 31-year-old Australian advises rivals to play their own games and keep the pressure on the world number one if they hope to derail her bid for a fifth Slam title in a row when the Flushing Meadows fortnight begins August 31. "No doubt she is going to be feeling the pressure, as much as you can when you've won four Slams in a row and going for a fifth," Stosur said. "You know she wants to get that calendar Slam. She's not immune to the nerves and pressure. "You have to go after it. Whatever it is you do, you have got to bring that at the big moments and make it happen." Coming off a clay-court title at Bad Gastein, second seed Stosur advanced to the quarter-finals of the WTA and ATP Washington Open with a 6-1, 7-5 victory Wednesday over American Irina Falconi.
