SAM STOSUR is aiming to at least match her breakthrough performance at last year’s French Open, having yesterday claimed her second career singles title in her first claycourt tournament since making the semi-finals at Roland Garros.The Queenslander will play just four claycourt tournaments culminating with next month’s return to the scene of her best grand slam result. She confirmed her credentials on what has quickly become a favourite surface by dominating Russian Vera Zvonareva 6-0, 6-3 in the final of the $US700,000 ($764,000) Family Circle Cup in Charleston, South Carolina. Stosur, 26, returned to the top 10 at Kim Clijsters’s expense on the strength of her performance on American green clay, and will now move to the red dirt of Europe for this weekend’s Fed Cup tie against the Ukraine – general flight availability permitting in the wake of the volcanic eruption in Iceland – before completing her build-up to the French Open, starting on May 23. Last year in Paris, the 30th-seeded Stosur held a break point against eventual champion Svetlana Kuznetsova at 2-2 in the third set before losing 6-4, 6-7 (5-7), 6-3.”I don’t want to get ahead of myself or anything like that, but having made the semis last year I’ve got to at least think I can try and do that again,” Stosur told the Herald from Charleston. ”And playing this well at the moment, if I can keep that going and keep improving my game leading into the French then I’d like to think I’ve got a good chance.”Grand slams are very different to normal weeks out on tour but I’ll be definitely at least trying to replicate that result I got last year and if I was able to do that then I’d be happy.”Stosur’s second WTA Tour title came six months after her maiden success in Osaka, and is the most prestigious of her career.
